Craniotomy and Craniectomy Scott 181 Views • 2 years ago

http://www.nucleushealth.com/ - This 3D medical animation depicts two operations, called craniotomy and craniectomy, in which the skull is opened to access the brain. The normal anatomy of the skull and tissues surrounding the brain are shown, including arteries and veins. The animation lists the common reasons for these procedures, and briefly introduces intracranial pressure.

Video ID: ANH13109

Transcript:

Your doctor may recommend a craniotomy or a craniectomy procedure to treat a number of different brain diseases, injuries, or conditions.

Your skull is made of bone and serves as a hard, protective covering for your brain. Just inside your skull, three layers of tissue, called meninges, surround your brain. The thick, outermost layer is the dura mater. The middle tissue layer is the arachnoid mater and the innermost layer is the pia mater. Between the arachnoid mater and the pia mater is the subarachnoid space, which contains blood vessels and a clear fluid called cerebrospinal fluid. Blood vessels, called bridging veins, connect the surface of your brain with the dura mater. Other blood vessels, called cerebral arteries, bring blood to your brain.

Inside your skull, normal brain function requires a delicate balance of pressure between the blood in your blood vessels, the cerebrospinal fluid that surrounds your brain, and your brain tissue. This is called normal intracranial pressure. Increased intracranial pressure may result from: brain tumors, head injuries, problems with your blood vessels, or infections in your brain or spinal cord. These conditions put pressure on your brain and may cause it to swell or change shape inside your skull, which can lead to serious brain injury.

Your doctor may recommend a craniotomy to remove: abnormal brain tissue, such as a brain tumor, a sample of tissue by biopsy, a blood clot, called a hematoma, excess cerebrospinal fluid, or pus from an infection, called an abscess.

A craniotomy may also be done to: relieve brain swelling,
stop bleeding, called a hemorrhage, repair abnormal blood vessels, repair skull fractures, or repair damaged meninges.

Finally, a craniotomy may also be done to: treat brain conditions, such as epilepsy, deliver medication to your brain, or implant a medical device, such as a deep brain stimulator.

The most common reason for a craniotomy is to remove a brain tumor.

How to Know If You Have a Hernia DrPhil 273 Views • 2 years ago

Do you think you have a hernia?
What are hernias?
The hernias we address in this http://DoctorsExpressHartsdale.com Medical Minute are inguinal, or groin, hernias. More common in men than women, an inguinal hernia can occur when part of the small intestine protrudes through a weakness or tear in the area between your abdomen and your thigh- or your groin. It's possible for anyone to get an inguinal hernia, but it is more commonly found in males.

Hernias form a bulge and can be accompanied by pain. Men have an approximate 26% lifetime risk of having hernia at some point in their life, where as women have a much lower chance of one- only about 3% of women will experience a hernia at some point in their life. There are other types of hernias, such as abdominal, or "hiatal" hernias but groin hernias outnumber abdominal hernias by about 3 to 1.

What causes a hernia?
The cause of a hernia is not always known, but hernias are often the result of weak spots in the abdominal wall. Weaknesses can be due to congenital defects (present at birth) or formed later in life. Some risk factors for inguinal hernia include:
• fluid or pressure in the abdomen
• heavy lifting
• straining during urination or bowel movements
• obesity
• chronic cough
• pregnancy

Hernias often form in people with weakened abdominal muscles or in those who do a lot of heavy lifting or straining, which is why we see it quite often in young men. Physiology plays a part: men have testicles and scrotum which descend through the inguinal canal-much larger in men than in women. That is part of the reason men tend to be more susceptible to hernias than women.

Symptoms of hernia

Symptoms of inguinal hernia usually include a bulge in the groin area and pain, pressure, or aching at the bulge—especially when lifting, bending, or coughing. These symptoms usually subside during rest periods. Men may also experience swelling around the testicles.

Screening and Diagnosis of Hernias
If you are having abdominal pain or pelvic bulge and pain, you want to see physician, and he or she will do an exam. They will use their finger, to see if you have a bulge in your scrotum or on your groin and they'll see if its reducible or not. If the exam doesn't give them the answer, they can then perform an ultrasound, an inexpensive test that can tell you the same day whether a hernia is present.

What to do if you think you have a hernia
Most of the time hernias do not cause problems. People often live with hernias their entire life without them becoming aggravated or painful. When they do cause pain though, there is concern that complications may have arisen. Most common hernias are what we call reducible; you can take your finger or you can lie down in bed and due to the effects of gravity, the bulge in the groin will actually disappear, which means the intestinal contents actually go back into the abdominal cavity or to the correct location. If it's not reducible by lying down or using a finger or having a physician trying to reduce it, then there are concerns about complications such as strangulation, or incarceration occurring. If those concerns are there, then you need to see a surgeon, and there may be a need for surgery.

How to Treat a Hernia
As stated earlier, hernias can often be watched for years without being treated. If however, they are causing pain, we generally refer you to a surgeon who can do a very simple laparoscopic surgery.

If you suspect a hernia, but have not been diagnosed, you should see your doctor, and of course, we are happy to see you here at Doctors Express

How to Start an IV | IV Catheter Insertion & Flush Technique in Hand | Nursing Skill nurse 173 Views • 2 years ago

How to start a peripheral IV in the dorsum of the hand: clinical nursing skill technique.

Starting an IV (intravenous catheter) can be an intimidating experience for nurses, especially nursing students and new nurses. However, nurses will perform IV insertions often, so this is an important nursing skill to learn.

Before starting an IV, always follow the protocols of your facility, as well as manufacturer's instructions for any supplies used.

In this video, Nurse Sarah demonstrates how to start a peripheral IV in the dorsum of the hand. Prior to inserting the IV, you'll want to do the following:

-Gather supplies
-Perform hand hygiene
-Prepare supplies (including priming the saline flush, removing air from extension tubing, opening packages, completing labels, and any other steps required by your facility.
-Locate a suitable vein
-Perform hand hygiene
-Don gloves

If the patient has a lot of hair, you might want to use clippers to trim the hairs prior to starting the IV. You may also apply a tourniquet to help veins move near the surface of the skin.

Next, you'll want to clean the site using the cleaner that came in the IV start kit, such as ChloraPrep.

Once the site has dried completely, you can insert the IV. Stabilize the vein with your non-dominant hand, and insert the IV's needle into the vein, watching carefully for blood return (or a blood flash) in the chamber. Advance the IV around 2mm more to ensure the plastic cannula is in the vein, then thread the cannula into the vein and press the needle safety button.
