QUOTE FOR WEDNESDAY:

“Kidney failure is a condition in which one or both of your kidneys no longer work on their own. Causes include diabetes, high blood pressure and acute kidney injuries. Symptoms include fatigue, nausea and vomiting, swelling, changes in how often you go to the bathroom and brain fog. Treatment includes dialysis or a kidney transplant.”

Cleveland Clinic (Kidney Failure: Stages, ESRD, Causes, Symptoms & Treatment)

Part IIIA March is kidney month – Chronic Kidney Failure: When it happens, causes, the symptoms, how its diagnosed and treated!

 

Chronic Renal or Kidney Disease (CRF):

In giving a short and easily understandable definition Chronic kidney disease happens when your kidneys no longer filter your blood the way they should, so wastes (toxins, usually end products of an acid) build up in your blood. This has probably been going on for years, and it may keep getting worse over time. Just like a car engine damaged but still using the car without getting the engine repaired sooner or later in time the engine no longer functions the same with any organ of the body getting damaged by some long term condition. If your disease gets worse and worse over time, you could have kidney failure or some multi organ failure, depending on the condition causing this.

Regarding Chronic Kidney Failure the causes can be:

** Diabetes (uncontrolled diabetes (Type 1 or 2) for many years.

** High blood pressure for many years.

These are the top 2 causes of most chronic kidney disease. Controlling these diseases can help slow or stop the damage to the individual’s kidneys who has one of these, if not both.

Other common causes of chronic renal failure (CRF) include:

-recurring pyelonephritis (kidney infection)

-polycystic kidney disease (multiple cysts in the kidneys

-autoimmune disorders such as systemic lupus erythematosus.

-hardening of the arteries, which can damage blood vessels in the kidney.

-A narrowed or blocked renal artery. A renal artery carries blood to the kidneys. Know this for starters, each of your kidneys has about a million tiny filters, called nephrons. The nephron is the tiny filtering structure in your kidneys. Each of your kidneys contain more than a million tiny filtering nephrons that help clean your blood removing toxins dumping them into your urinary bladder so you can evacuate them though urine (urea, urine; get it). Your nephrons play a vital role to our essential daily living. If over a long time you have a renal artery blocked the nephrons stop their function and die.

Remember the nephrons help all humans do the following if there kidneys or one kidney is functioning properly:

-Remove excess water, wastes (like urea, ammonia, etc.) & other substances from your blood.

-Return substances like sodium, potassium or phosphorus to the body whenever any of these substances run llow in your body or do the opposite if they run high to evacuate them through voiding dumping the sodium or phosphorus or potassium in the urinary bladder through the tube from the kidneys to the urinary bladder called ureters.

**If nephrons are damaged by the high sugar content or high blood pressure in the kidneys, they stop working. For a while, healthy nephrons can take on the extra work or overload. But if the damage continues, more and more nephrons shut down. After a certain point, the nephrons that are left cannot filter your blood well enough to keep you’re blood filtered properly to keep you healthy. Just like running from a bear in the street chancing you. We can run only so long but sooner or later we will run out of energy and not be able to run anymore, same concept for the kidney nephrons when they run out of enough energy due to the kidneys not properly working.**

The symptoms can be:

Urinate less than normal.

Have swelling and weight gain from fluid buildup in your tissues. This is called edema.

Feel very tired or sleepy.

Not feel hungry, or you may lose weight without trying.

Often feel sick to your stomach (nauseated) or vomit.

Have trouble sleeping.

Have headaches or trouble thinking clearly.

So what will you do GO TO A DOCTOR OR CALL 911 AND GO TO THE ER:

Your doctor will do blood and urine tests to help find out how well your kidneys are working. These tests can show signs of kidney disease and anemia. (You can get anemia from having damaged kidneys.) You may have other tests to help rule out other problems that could cause your symptoms.

To diagnose chronic renal failure is pretty much the same tests that are listed above on acute renal failure plus:

Chronic kidney disease is also called chronic renal failure or chronic renal insufficiency.There are five stages of kidney disease, from kidney damage with normal GFR to kidney failure.  So GFR will help the MD rule out acute versus chronic to give the MD direction on Rx.Your doctor will ask questions about any past kidney problems. He or she will also ask whether you have a family history of kidney disease and what medicines you take, both prescription and over-the-counter drugs.

Diagnosis & Treatment (Rx) for Chronic Kidney (Renal) Failure (CRF):

There are things you can do to slow or stop the damage to your kidneys. Taking medicines and making some lifestyle changes can help you manage your disease, prevent further damage to the kidneys, if their functioning at all and make you possibly feel better.

Kidney disease is a complex problem. You will probably need to take a number of medicines and have many tests. To stay as healthy as possible, take your medicines just the way your doctor says to and work closely with your doctor.

Go to all your appointments for the MD to see a increase in function or decrease in function of your kidney or kidneys you have still functioning to a level. To do that you can’t just go every 6 months especially when first diagnosed with it or with a collapse of an exacerbation of kidney failure in a worse level that brought on new symptoms that brought you to the ER.

Lifestyle changes are an important part of your treatment. Taking these steps can help slow down kidney disease and reduce your symptoms. These steps may also help with high blood pressure, diabetes, and other problems that make kidney disease worse or made the kidney disease happen with the secondary diagnosis you had originally for years (ex. Hypertension or Diabetes if not both especially is uncontrolled)

Very hard, never a complete 100 % resolution. It is like emphysema done by smokers the damage is done or like a heart attack the area of the infarction=damage is already done to the heart muscle.

Scared now, understandable but unfortunately the damage is done, so its get the organ to its optimal level of functioning or replace the damaged kidney (s) through a transplant of one.  You need to know this, do it if you want to live LONGER.  Remember fear is fear itself, the fear run it over and deal with what you have and make your life longer & better!  It’s all up to you.  HANDSOME I know you can do it , I am there for you as a good friend and professional RN and I would love you to last longer John!! XO

You may have a test done that lets your doctor look at a picture of your kidneys, such as an ultrasound or CT (Cat Scan of the kidneys). These tests can help your doctor measure the size of your kidneys, estimate blood flow to the kidneys, and see if urine flow is blocked. In some cases, your doctor may take a tiny sample of kidney tissue (biopsy) to help find out what caused your kidney disease.

Chronic kidney disease is caused by damage of the kidneys whether the cause of it be primary a Renal or Kidney problem or a secondary, another disease or disorder that affects the kidneys in doing their job, like hyperglycemia related to a individual with uncontrolled diabetes, for instance.

Chronic kidney disease may seem to have come on suddenly. But it has been happening bit by bit for many years as a result of damage to your kidneys.

One way to measure how well your kidneys are working is to figure out your glomelular filtration rate (GFR). The GFR is usually calculated using results from your blood creatinine test.

Then the stage of kidney disease is figured out using the GFR (glomelular filtration rate). There are five stages of kidney disease, from kidney damage with normal GFR to kidney failure.

Your doctor will do tests that measure the amount of urea (BUN) and creatinine in your blood. These tests can help measure how well your kidneys are filtering your blood. As your kidney function gets worse, the amount of nitrogen (shown by the BUN test) and creatinine in your blood increases. The level of creatinine in your blood is used to find out the glomerular filtration rate (GFR). The GFR is used to show how much kidney function you still have. The GFR is also used to find out the stage of your kidney disease your in if you have it and its to guide decisions about treatment. *

QUOTE FOR TUESDAY:

“Acute kidney injury happens when the kidneys suddenly can’t filter waste products from the blood. When the kidneys can’t filter wastes, harmful levels of wastes may build up. The blood’s chemical makeup may get out of balance.

Acute kidney injury used to be called acute kidney failure. Acute kidney injury is most common in people who are in the hospital, mostly in people who need intensive care.

Acute kidney injury ranges from mild to severe. If severe, ongoing and not treated, it can be fatal. But it also can be reversed. People in otherwise good health may get back typical or nearly typical use of their kidneys.”

MAYO CLINIC (Acute kidney injury – Symptoms and causes – Mayo Clinic)

Part II March is kidney month – Acute Kidney Damage

ARF VERSUS CRF1

Acute Renal (Kidney) Failure:

Kidney failure occurs when the kidneys lose their ability to function. To treat kidney failure effectively, it is important to know whether kidney disease has developed suddenly (acute) or over the long term (chronic). Many conditions, diseases, and medicines can create situations that lead to acute and chronic kidney disease. Acute kidney injury, also called acute renal failure, is more commonly reversible than chronic kidney failure since the chronic condition has lasted longer in the body affecting systems for several months to years (some decades). Acute Renal Failure is new to the body as opposed to chronic; making it higher odds this can be treated and cured.

When acute kidney injury (ARF) occurs, the kidneys are unable to remove waste products and excess fluids, which then build up in the body and upset the body’s normal chemical balance.*

The most common causes of acute kidney injury are:

-dehydration

-blood loss from major surgery or injury

-medicines such as nonsteroidal anti-inflammatory drugs (NSAIDs), antibiotics, or the dyes (contrast agents) used in X-ray tests.

Symptoms depend on the cause of acute renal failure and can include:

    • -Little or no urine output.
    • -Dizziness upon standing.
    • -Swelling, especially of the legs and feet.
    • -Loss of appetite, nausea, and vomiting.
    • -Feeling confused, anxious and restless, or sleepy.
    • -Pain in the flank, which is felt just below the rib cage and above the waist on one or both sides of the back.*

If your signs and symptoms suggest that you have acute kidney failure, your doctor may recommend certain tests and procedures to verify your diagnosis. These may include:

  • Urine output measurements. The amount of urine you excrete in a day may help your doctor determine the cause of your kidney failure.
  • Urine tests. Analyzing a sample of your urine, a procedure called urinalysis, may reveal abnormalities that suggest kidney failure.
  • Blood tests. A sample of your blood may reveal rapidly rising levels of urea and creatinine — two substances used to measure kidney function.  Most cases of acute kidney injury occur in people who are already in the hospital for other reasons. In these people, acute kidney injury is usually diagnosed when routine tests show a sudden increase in creatinine and blood urea nitrogen (BUN) levels.   **A buildup of these waste products in the blood points to a loss of kidney function!**
  • With a patient just coming in the first time to an MD with no history of renal disease but has factors or symptoms indicating possible kidney failure involvement don’t be surprised if the doctor orders glomerular filtration rate (GFR); which is a test used to check how well the kidneys are working. Specifically, it estimates how much blood passes through the glomeruli each minute. Glomeruli are tiny filters in the kidneys that filter waste from the blood.
  • Imaging tests. Imaging tests such as ultrasound and computerized tomography may be used to help your doctor see your kidneys.  Also commonly done is an ultrasound of the kidneys which may help determine whether kidney problems are acute or chronic. Normal-sized kidneys may be present in either condition, but when both kidneys are smaller than normal, chronic kidney disease is usually the problem.  This helps rule out acute from chronic.correcting the cause and supporting the kidneys with dialysis until proper functioning is restored.
  • Removing a sample of kidney tissue for testing. In some situations, your doctor may recommend a kidney biopsy to remove a small sample of kidney tissue for lab testing. Your doctor inserts a needle through your skin and into your kidney to remove the sample.

TREATMENT FOR ARF (reversible in most cases):

Treatment for acute kidney failure typically requires a hospital stay. Most people with acute kidney failure are already hospitalized. How long you’ll stay in the hospital depends on the reason for your acute kidney failure and how quickly your kidneys recover.

In some cases, you may be able to recover at home.

Treating the underlying cause of your AKF:

Treatment for acute kidney failure (AKF) involves identifying the illness or injury that originally damaged your kidneys. Your treatment options depend on what’s causing your kidney failure.

Part I March is Kidney Month – The importance of kidneys and know its functions to understand kidney failure.

kidney 3

    kidney failure

The kidneys are important organs with many functions in the body, including producing hormones, absorbing minerals, and filtering blood and producing urine. While they are important and kidney failure can be fatal, a human only needs one healthy kidney to survive.

The kidneys are two bean-shaped organs that extract waste from blood, balance body fluids, form urine, and aid in other important functions of the body.

They reside against the back muscles in the upper abdominal cavity. They sit opposite each other on either side of the spine. The right kidney sits a little bit lower than the left to accommodate the liver.

When it comes to components of the urinary system, the kidneys are multi-functional powerhouses of activity, for if the kidneys aren’t working, meaning they don’t filter toxic wastes out of our blood stream (with other functions it does) than the waste products don’t get dumped into the urinary bladder from the renal tubes, called right and left ureters. In human anatomy, the ureters are tubes made of smooth muscle fibers that propel urine from the kidneys to the urinary bladder. If the kidneys are not working they are not filtering our blood (same principle as filtering beer to make it to perfection, the kidneys do it for our blood to be able to have the cells do their function to the optimal levels with keeping toxins out of the body in preventing many blood problems with more due to acidosis (toxin build up). In the adult, the ureters are usually 25–30 cm (10–12 in) long and ~3–4 mm in diameter.

The kidneys have multiple functions! Some of the core actions of a healthy kidney or kidneys of a human body include:

  • Waste excretion: There are many things your body doesn’t want inside of it. The kidneys filter out toxins, excess salts, and urea (a toxin), a nitrogen-based waste created by cell metabolism.
  • * Urea is an organic chemical compound and is essentially the waste produced by the body after metabolizing protein. Naturally the compound urea is produced when the liver breaks down protein or amino acids, and ammonia, the kidneys then transfer the urea from the blood to the urine, when they do filtering of the blood.  Urea is a byproduct of protein metabolism, the ending result. Extra nitrogen is expelled from the body through urea because it is extremely soluble (solid); it is a very efficient process. The average person excretes about 30 grams of urea a day, mostly through urine but a small amount is also secreted in perspiration. Synthetic versions of the chemical compound can be created in liquid or solid form and is often an ingredient found in fertilizers, animal food, and diuretics, just to name a few . Urea is what gives our urine the color yellow.         In the gastrointestinal tract, blood proteins are broken down into ammonia (could be due to high protein eating to drugs with actual conditions); and goes to the liver converting it to Urea. It is then released into the blood stream where the kidney’s take it up and eliminate it. Urea is then eliminated by the kidney’s, but not produced by it.  Urea is synthesized in the liver and transported through the blood to the kidneys for removal.
  •  A Healthy Kidney or Kidneys functions in the human body doing:
  • Water level balancing: As the kidneys are key in the chemical breakdown of urine, they react to changes in the body’s water level throughout the day. As water intake decreases, the kidneys adjust accordingly and leave water in the body instead of helping excrete it which aides in electrolyte balancing in the blood with keeping the body hydrated properly.
  • Blood pressure regulation: The kidneys need constant pressure to filter the blood. When it drops too low, the kidneys increase the pressure. One way is by producing a blood vessel-constricting protein (angiotensin) that also signals the body to retain sodium and water. Both the constriction and retention help restore normal blood pressure.
  • Red blood cell regulation: When the kidneys don’t get enough oxygen, they send out a distress call in the form of erythropoietin, a hormone that stimulates the bone marrow to produce more oxygen-carrying red blood cells.
  • Acid regulation: As cells metabolize, they produce acids. Foods we eat can either increase the acid in our body or neutralize it. If the body is to function properly, it needs to keep a healthy balance of these chemicals. The kidneys do that, too.Because of all of the vital functions the kidneys perform and the toxins they encounter, the kidneys are susceptible to various problems.
  • Acute kidney failure is a condition in which the kidneys suddenly lose their ability to function properly. This can occur for many reasons, including:

  • Infection
  • Blood-clotting disorders
  • Decreased blood flow caused by low blood pressure
  • Autoimmune kidney disorders
  • Urinary tract infections
  • Complications from pregnancy
  • Most people are born with two kidneys, but many people can live on just one. Kidney transplant surgeries with live donors are common medical procedures today. *
  • Chronic kidney failure – same as acute in that the kidney (s) loses its function. 
  • DehydrationDiseases and conditions that commonly cause chronic kidney disease include:
  • Type 1 or type 2 diabetes.
  • High blood pressure
  • Glomerulonephritis (gloe-mer-u-lo-nuh-FRY-tis), an inflammation of the kidney’s filtering units (glomeruli)
  • Interstitial nephritis, an inflammation of the kidney’s tubules and surrounding structures
  • Polycystic kidney disease
  • Prolonged obstruction of the urinary tract, from conditions such as enlarged prostate, kidney stones and some cancers
  • Vesicoureteral (ves-ih-koe-yoo-REE-ter-ul) reflux, a condition that causes urine to back up into your kidneys
  • Recurrent kidney infection, also called pyelonephritis (pie-uh-lo-nuh-FRY-tis)
  • A chronic condition caused the failure to happen called a secondary diagnosis.

QUOTE FOR THE WEEKEND:

“National Sleep Awareness Week is March 9 – 15 –You spend about one-third of your life sleeping, but it’s still something many struggle with. Researchers and experts also struggle with it because of the mysteries surrounding how and why we sleep and what happens to us while we do. Fortunately, advances in medical science are helping people find ways to get the sleep they need.

What is sleep?

Sleep is a normal body process that allows your body and brain to rest. At first glance, sleep is deceptively simple. For most people, it’s just a matter of getting comfortable, closing your eyes and drifting into slumber. But despite how simple it seems, sleep is one of the most complex and mysterious body processes known to science.”

World Sleep Week Awareness!

Tips to Making Better Sleep

May is Better Sleep Month! Take advantage of this time to create better sleep habits that lead to more restful sleep for a lifetime. We’ve created a list of tips on how to encourage better, healthier sleep at night, naturally. Challenge yourself to put them in practice for the rest of Better Sleep Month—and, hopefully, thereafter.

1.)  Create a Sleep Schedule

Try going to bed at the same time every night and waking up at the same time every morning, even on the weekends. Sticking to a sleep schedule will train your body to recognize your set bedtime and allow you to adapt to a proper waking and sleeping cycle. If you frequently change the time you wake up or go to bed, your body won’t be able to adjust to a regular sleep schedule. Make an effort to schedule times that leave room for about eight hours of sleep each night. To help you stay on track with your new May sleep schedule, mark your calendar with the times you wake up and go to bed each day. Using your sleep calendar to log which days you aren’t falling asleep at the proper time might help you identify the reasons why—for example, drinking too much coffee late in the afternoon or stress from a big day at work. Writing out your sleep schedule and any troubles will help you visualize the steps you can take to improve your sleeping patterns.

2.)  Stick to a Rigid Bedtime Routine

Daily activities impact your circadian rhythm and allow your body to anticipate upcoming events. Our bodies crave consistency, so developing a rigid bedtime routine will help signal to your body when it’s time to rest. Create a bedtime prep checklist to ensure you are preparing your body and brain for sleep the same way nightly. Good nighttime rituals include reading, meditating, brushing your teeth, closing the blinds, and getting under the covers. Your bedtime routine is personal to you, so take some time this month to think about the steps you’ll take to prepare yourself for quality sleep most comfortably.

3.)  Turn Off Electronics

Light cues from your environment can be detrimental to your sleep patterns and circadian rhythm. The light from electronics works as a stimulant in your brain, sending a confusing signal to wake up when it may actually be time for bed. Challenge yourself to keep electronics out of your bedroom this month, and record the nights you are successful on your sleep calendar for motivation. Put your phone and laptop in another room and click off your television before beginning your bedtime rituals. Try using a traditional alarm clock instead of your phone to avoid the temptation to check your texts or emails before bed. Your body and mind will thank you for the opportunity to relax and wind down in a dark space so you can easily fall and stay asleep.

Stop Hitting Snooze

Make May the month you stop hitting the snooze button in the morning. Although getting an extra five minutes of sleep sounds pleasant, it’s actually more harmful than beneficial for your body. Snoozing your alarm is detrimental to your natural sleeping patterns and damages the consistency your body has been working so hard to achieve. It can also make you feel more tired or groggy throughout the day. If you are an avid snoozer, try putting your alarm clock on the other side of the room this month to force yourself to get out of bed to turn it off.

Make Sleep a Priority in your life

Hold yourself accountable to making better sleep a priority today and thereafter. While it’s important to do this always, concentrating on healthy sleep habits for just one month could set you up for a lifetime of quality sleep. If you succeed at doing these sleeping changes, you might just have restful nights and productive days and reach the goal you have wanted for so long, good sleep.

“Key points

  • A TBI affects how the brain works.
  • TBI is a major cause of death and disability.
  • TBIs may be missed in older adults.
  • A TBI may lead to short- or long-term health problems.
  • A TBI during childhood may affect brain development.

There were over 69,000 TBI-related deaths in the United States in 2021.1 That’s about 190 TBI-related deaths every day.

TBIs affect the lives of people of all ages. Anyone can experience a TBI, but data suggest that some groups are at greater risk of dying from a TBI or experiencing long-term health problems after the injury .

Center for Disease Control and Prevention – CDC (Facts About TBI | Traumatic Brain Injury & Concussion )

 

 

 

Part III National Brain Injury Awareness Month!

What are the causes?

Common causes include falls, car or motorcycle crashes, vehicular accidents involving pedestrians, athletics, and assaults with or without a weapon.

Who is affected?

Approximately 1.5 to 2 million adults and children suffer a traumatic brain injury (TBI) each year in the United States. Most people who experience a head injury, about 1.1 million, will have a mild injury that does not require an admission to the hospital. Another 235,000 individuals will be hospitalized with a moderate to severe head injury, and approximately 50,000 will die.

How is a diagnosis made?

When a person is brought to the emergency room with a head injury, doctors will learn as much as possible about his or her symptoms and how the injury occurred. The person’s condition is assessed quickly to determine the extent of injury.

The Glasgow Coma Score (GCS) is a 15-point test used to grade a patient’s level of consciousness. Doctors assess the patient’s ability to 1) open his or her eyes, 2) ability to respond appropriately to orientation questions, (“What is your name? What is the date today?”), and 3) ability to follow commands (“Hold up two fingers, or give a thumbs up”). If unconscious or unable to follow commands, his or her response to painful stimulation is checked. A number is taken from each category and added together to get the total GCS score. The score ranges from 3 to 15 and helps doctors classify an injury as mild, moderate, or severe. Mild TBI has a score of 13-15. Moderate TBI has a score of 9-12, and severe TBI has a score of 8 and below.

Diagnostic imaging tests will be performed:

CT of TBI

Figure 3. CT scan shows a blood clot (hematoma) collecting under the bone (red arrows) and displacing brain (yellow arrow) to the other side of the skull.

  • Computed Tomography (CT) is a noninvasive X-ray that provides detailed images of anatomical structures within the brain. A CT scan of the head is taken at the time of injury to quickly identify fractures, bleeding in the brain, blood clots (hematomas) and the extent of injury (Fig. 3). CT scans are used throughout recovery to evaluate the evolution of the injury and to help guide decision-making about the patient’s care.
  • Magnetic Resonance Imaging (MRI) is a noninvasive test that uses a magnetic field and radiofrequency waves to give a detailed view of the soft tissues of the brain. A dye (contrast agent) may be injected into the patient’s bloodstream. MRI can detect subtle changes in the brain that cannot be seen on a CT scan.
  • Magnetic Resonance Spectroscopy (MRS) gives information about the metabolism of the brain. The numbers generated from this scan provide a general prognosis about the patient’s ability to recover from the injury.

What treatments are available?

Mild TBI usually requires rest and medication to relieve headache. Moderate to severe TBI require intensive care in a hospital. Bleeding and swelling in the brain can become an emergency that requires surgery. However, there are times when a patient does not require surgery and can be safely monitored by nurses and physicians in the neuroscience intensive care unit (NSICU).

The goals of treatment are to resuscitate and support the critically ill patient, minimize secondary brain injury and complications, and facilitate the patient’s transition to a recovery environment. Despite significant research, doctors only have measures to control brain swelling, but do not have a way to eliminate swelling from occurring.

Neurocritical care
Neurocritical care is the intensive care of patients who have suffered a life-threatening brain injury. Many patients with severe TBI are comatose or paralyzed; they also may have suffered injuries in other parts of the body. Their care is overseen by a neurointensivist, a specialty-trained physician who coordinates the patient’s complex neurological and medical care. Patients are monitored and awakened every hour for nursing assessments of their mental status or brain function.

Figure 4. In the NSICU, the patient is connected to numerous machines, tubes, and monitors. The monitoring equipment provides information about body functions and helps guide care. Some equipment may take over certain functions, such as breathing, nutrition, and urination, until the patient’s body is able to do these things on its own.

Seeing a patient who has suffered a severe TBI can be shocking. It is possible that your loved one’s appearance will be altered because of facial injury and equipment that is used for monitoring. Numerous tubes, lines, and equipment may be used to closely monitor his or her heart rate, blood pressure, and other critical body functions. (Fig. 4)

ICP monitor

Figure 5. A brain oxygen and cerebral blood flow monitor is inserted into the brain tissue and secured to the skull with a bolt. A catheter is inserted into the ventricle of the brain to monitor intracranial pressure (ICP). If pressure is too high, the CSF fluid can be drained from the ventricles.

  • Intracranial pressure (ICP) monitor. A catheter is placed through a small hole in the skull and positioned inside the ventricle (fluid-filled area deep within the brain) to measure pressure inside the head (Fig. 5). The ICP monitor allows the NSICU team to intervene quickly if the pressure becomes too high. Typical intracranial pressure is less than 20 mmHg. However, there are times when a higher number is safe and acceptable.
  • Brain oxygen monitor (Licox). A catheter is placed through a small hole in the skull and positioned within the brain tissue. The Licox measures the oxygen level and temperature within the brain. Adjustments in the amount of oxygen given to the patient are often made to maximize the brain’s oxygen level. A cerebral blood flow monitor, called a Hemedex, is a newer monitor that is placed with the Licox and helps the NSICU team evaluate blood flow through the brain.
  • Ventilator. Some patients may require a ventilator, a machine that helps them breathe. The ventilator is connected to the patient by the endotracheal tube, or ET tube. The tube is placed into the patient’s mouth and down into the trachea, or windpipe. The tube allows the machine to push air into and out of the lungs, thereby helping the patient breathe.
  • Feeding tube. When patients are on a ventilator or have a decreased level of alertness, they may not be able to eat or get sufficient nutrition to meet their needs. A nasal-gastric feeding tube may be inserted through the patient’s nose and passed down the throat into the stomach. It delivers liquid nutrition as well as any medication that is required.
  • Seizures and EEG monitoring. A seizure is an abnormal electrical discharge from the brain. Approximately 24% of patients who suffer a TBI will have a seizure that is undetected unless they are monitored by an electroencephalogram (EEG). Seizures that are not visible to the human eye are referred to as non-convulsive seizures. Because these seizures are serious, all patients with a severe TBI are monitored with continuous EEG for 24 to 72 hours after injury.

Medication

  • Sedation and pain. After a head injury it may be necessary to keep the patient sedated with medications. These medications can be turned off quickly in order to awaken the patient and check their mental status. Because patients often have other injuries, pain medication is given to keep them comfortable.
  • Controlling intracranial pressure. Hypertonic saline is a medication used to control pressure within the brain. It works by drawing the extra water out of the brain cells into the blood vessels and allowing the kidneys to filter it out of the blood.
  • Preventing seizures. Patients who’ve had a moderate to severe traumatic brain injury are at higher risk of having seizures during the first week after their injury. Patients are given an anti-seizure medication (levetiracetam or phenytoin) to prevent seizures from occurring.
  • Preventing infection. Although every attempt is made to prevent infection, the risk is always present. Any device placed within the patient has the potential to introduce a microbe. If an infection is suspected, a test will be sent to a laboratory for analysis. If an infection is present, it will be treated with antibiotics.

Surgery

Surgery is sometimes necessary to repair skull fractures, repair bleeding vessels, or remove large blood clots (hematomas). It is also performed to relieve extremely high intracranial pressure.

  • Craniotomy involves cutting a hole in the skull to remove a bone flap so that the surgeon can access the brain. The surgeon then repairs the damage (e.g., skull fracture, bleeding vessel, remove large blood clots). The bone flap is replaced in its normal position and secured to the skull with plates and screws.

Figure 6. A large decompressive craniectomy is removed and the dura is opened to allow the brain to expand. Blood clots are removed and bleeding vessels are repaired. The bone flap is frozen and replaced about 6 weeks later.

  • Decompressive craniectomy involves removing a large section of bone so that the brain can swell and expand. This is typically performed when extremely high intracranial pressure becomes life threatening. At that time the patient is taken to the operating room where a large portion of the skull is removed to give the brain more room to swell (Fig. 6). A special biologic tissue is placed on top of the exposed brain and the skin is closed. The bone flap is stored in a freezer. One to 3 months after the swelling has resolved and the patient has stabilized from the injury, the bone flap is replaced in another surgery, called cranioplasty.

Other surgical procedures may be performed to aid in the patient’s recovery:

  • Tracheotomy involves making a small incision in the neck to insert the breathing tube directly into the windpipe. The ventilator will then be connected to this new location on the neck and the old tube is removed from the mouth.
  • Percutaneous Endoscopic Gastrostomy Tube (PEG) is a feeding tube inserted directly into the stomach through the abdominal wall. A small camera is placed down the patient’s throat into the stomach to aid with the procedure and to ensure correct placement of the PEG tube (see Surgical Procedures for Accelerated Recovery).

Clinical trials

Clinical trials are research studies in which new treatments—drugs, diagnostics, procedures, and other therapies—are tested in people to see if they are safe and effective. Research is always being conducted to improve the standard of medical care. Information about current clinical trials, including eligibility, protocol, and locations, are found on the Web. Studies can be sponsored by the National Institutes of Health (see clinicaltrials.gov) as well as private industry and pharmaceutical companies (see www.centerwatch.com).

Recovery & prevention

The recovery process varies depending on the severity of the injury, but typically progresses through stages: coma, confusion / amnesia, and recovery.

  • When a patient is in a coma, his or her eyes are closed and they show minimal reaction when spoken to or stimulated. Movements that may be seen at this time are basic reflexes or automatic responses to a stimulus. The brain wave activity in a comatose person is very different from that of a sleeping person.
  • When a patient begins to awaken, the first natural response is that of bodily protection. Patients at this stage will move away from any stimulus or tend to pull at items attached to them in an attempt to remove anything that is uncomfortable or irritating. His or her eyes may be open more often, but they may not be aware of their behavior or be able to interact in a meaningful way. It is common for a patient to respond to each stimulus (hearing, seeing, or touching) in the same way. Responses may include increased rate of breathing, moaning, moving, sweating, or a rise in blood pressure.
  • As the patient continues to wake up, their interactions may become more purposeful. They may look at a person and follow them around the room with their eyes, or follow simple commands such as “Hold up your thumb.” Patients tend to be confused and may have inappropriate or agitated behaviors.

Not all head injuries are the same. Patients recover at different rates and to varying degrees. It is difficult to determine at what point a patient will start understanding and interacting with their caregivers or family in a meaningful way. It is important to have patience; recovery from a brain injury can take weeks, months, or even years.

The Family’s Role
Many family members express feelings of helplessness when their loved one is in the NSICU. You are not alone. Please take care of yourself and use your energy wisely.

Visiting hours are limited in the NSICU. Too much stimulation can agitate the patient and raise his or her blood pressure. You can most effectively convey your concern by sitting quietly and holding your loved one’s hand. Be aware that the patient, though silent, may hear anything you say. Never speak as if the patient were not there.

As patients recover, they need help understanding what has happened to them during this “lost period of time.” Keep in mind that the recovery of consciousness is a gradual process – not just a matter of waking up. Progress is usually tracked in three areas: movement, thinking, and interacting. You can help by keeping a diary of their progress. Family photos may help with regaining memory.

Rehabilitation
Most patients are discharged from the hospital when their condition has stabilized and they no longer require intensive care. A social worker will work closely with the family as preparations are made for a return home or for transfer to a long-term care or rehabilitation center.

  • A long-term acute care (LTAC) facility is a place for patients who have stabilized from their initial injury but who still require a ventilator or frequent nursing care. Many patients are discharged to an LTAC to continue being weaned from the ventilator. Once off the ventilator, they can be moved to a rehabilitation or skilled nursing facility.
  • A rehabilitation facility is a place for patients who do not require a ventilator but who still require help with basic daily activities. Physical and occupational therapists work with patients to help them achieve their maximum potential for recovery. Rehab facilities are either Acute Inpatient Rehab that require patients to participate in 3 hours or more of rehab a day or a Skilled Nursing Facility (SNF) that provide 1-3 hours of rehab a day depending on what the patient can tolerate.

Recovering from a brain injury relies on the brain’s plasticity—the ability for undamaged areas of the brain to take over functions of the damaged areas. It also relies on regeneration and repair of nerve cells. And most importantly, on the patient’s hard work to relearn and compensate for lost abilities.

  • A physical therapist helps patients rebuild and maintain strength, balance, and coordination. They can work with the patient in any facility.
  • An occupational therapist helps patients to perform activities of daily living, such as dressing, feeding, bathing, toileting, and transferring themselves from one place to another. They also provide adaptive equipment if a patient has difficultly performing a task.
  • A speech therapist helps patients by monitoring their ability to safely swallow food and helping with communication and cognition.
  • A neuropsychologist helps patients relearn cognitive functions and develop compensation skills to cope with memory, thinking, and emotional needs.

Prevention

Tips to reduce the risk for a head injury:

  • Always wear your helmet when riding a bicycle, motorcycle, skateboard, or all-terrain vehicle.
  • Never drive under the influence of alcohol or drugs.
  • Always wear your seat belt and ensure that children are secured in the appropriate child safety seats.
  • Avoid falls in the home by keeping unsecured items off the floor, installing safety features such as non-slip mats in the bathtub, handrails on stairways, and keeping items off of stairs.
  • Avoid falls by exercising to increase strength, balance, and coordination.
  • Store firearms in a locked cabinet with bullets in a separate location.
  • Wear protective headgear while playing sports.
