If the artery were severed, blood would flow out unimpeded, although the artery wall would contract in an effort to stop the bleeding. After losing >30% of one's blood volume blood pressure would start dropping, and with less pressure the rate of bleeding would go down. At this stage if the blood loss wasn't replaced the person could die. Losing halve to two thirds of one's blood volume is considered to be fatal even if later on blood transfusion is attempted. One's total blood volume at 70ml/kg is estimated to be between 5 to 7 liters, so that makes a blood loss of between 2,5 to 4,7 L.

Thoracentesis is a procedure used to obtain a sample of fluid from the space around the lungs. Normally, only a thin layer of fluid is present in the area between the lungs and chest wall. However, some conditions can cause a large amount of fluid to accumulate. This collection of fluid is called a pleural effusion.

A ventricular septal defect (VSD) is an opening or hole in the wall that separates the two lower chambers of the heart. This wall is called the ventricular septum. The hole causes oxygen-rich blood to leak from the left side of the heart to the right side. This causes extra work for the right side of the heart, since more blood than necessary is flowing through the right ventricle to the lungs. The hole is usually closed with surgery. However, in certain situations, your child's cardiologist and surgeon may think it is best to close the hole with a special device. This procedure is done in the heart catheterization lab.

Surgical site infections (SSIs) remain a prevalent threat to patient safety. Proper surgical hand scrub or rub techniques are essential to decreasing the incidence of SSIs. This video provides instructions on the anatomical surgical hand scrub procedure using the brushstroke method.

Spinal stenosis can put pressure on the spinal cord and the nerves within the spine. It commonly occurs in the neck and lower back. The condition is often caused by age-related wear and tear. Symptoms, if they occur, include pain, numbness, muscle weakness, and impaired bladder or bowel control. Treatment includes medication, physical therapy, and possibly surgery

he inflatable penile prosthesis consists of two attached cylinders -- a reservoir and a pump -- which are placed surgically in the body. The two cylinders are inserted in the penis and connected by tubing to a separate reservoir of saline. The reservoir is implanted under the rectus muscles in the lower abdomen.

esophago-gastro- duodinoscopy
Gastroduodinoscopy requires special training and considerable experience but affords valuable information.
By its implement the whole of the interior of the stomach as well as esophagus, the first part and the proximal section of the second part of the duodenum and both efferent and afferent loops of the gastrojujenostomy if present can be scrutinized.
Gastroscopy is valuable in the diagnosis of gastric ulcers, in checking the results of medical treatment of chronic gastric ulcer. Gastroduodinoscopy is valuable in differential diagnosis between chronic peptic ulcer and gastric carcinoma, in diagnosis of small gastric neoplasm, in the detection of certain forms of gastritis, in examination of a stoma, in cases of gastrojujenostomy, in cases of duodinitis and duodenal ulcer.

Focal seizures (also called partial seizures [citation needed] and localized seizures) are seizures which affect initially only one hemisphere of the brain. [citation needed] The brain is divided into two hemispheres, each consisting of four lobes – the frontal, temporal, parietal and occipital lobes.

This medical animation shows laparoscopically assisted gallbladder removal surgery, or cholecystectomy. The animation begins by showing the normal anatomy of the liver and gallbladder. Over time, gallstones form within the gallbladder, blocking the cystic duct, and causing the gallbladder to become enlarged and inflamed. The procedure, sometimes called a "lap-chole", begins with the insertion of four trocar devices, which allow the physician to see inside the abdomen without making a large incision. Air is added to the abdominal cavity to make it easier to see the gall bladder. Next, we see a view through the laparascope, showing two surgical instruments grasping the gallbladder while a third severs the cystic duct. After the gallbladder is removed, the camera pans around to show that the cystic artery and vein, have already been clipped to prevent bleeding.

Restrictive cardiomyopathy (RCM) is a rare form of heart muscle disease that is characterized by restrictive filling of the ventricles. In this disease the contractile function (squeeze) of the heart and wall thicknesses are usually normal, but the relaxation or filling phase of the heart is very abnormal.

Neonatal resuscitation skills are essential for all health care providers who are involved in the delivery of newborns. The transition from fetus to newborn requires intervention by a skilled individual or team in approximately 10% of all deliveries. This figure is concerning because 81% of all babies in the United States are born in nonteaching, nonaffiliated level I or II hospitals. In such hospitals, the volume of delivery service may not be perceived as sufficient economic justification for the continuous in-hospital presence of personnel with high-risk delivery room experience, as recommended by the American Academy of Pediatrics (AAP) and the American College of Obstetricians and Gynecologists (ACOG). [1] Perinatal asphyxia and extreme prematurity are the 2 complications of pregnancy that most frequently necessitate complex resuscitation by skilled personnel. However, only 60% of asphyxiated newborns can be predicted ante partum. The remaining newborns are not identified until the time of birth. Additionally, approximately 80% of low-birth-weight infants require resuscitation and stabilization at delivery. Nearly one half of newborn deaths (many of which involve extremely premature infants) occur during the first 24 hours after birth. Many of these early deaths also have a component of asphyxia or respiratory depression as an etiology. For the surviving infants, effective management of asphyxia in the first few minutes of life may influence long-term outcome. Even though prenatal care can identify many potential fetal difficulties ante partum, allowing maternal transfer to the referral center for care, many women who experience preterm labor are not identified prospectively and therefore are not appropriately transferred to a tertiary perinatal center. Consequently, many deliveries of extremely premature infants occur in smaller hospitals. For this reason, all personnel involved in delivery room care of the newborn should be trained adequately in all aspects of neonatal resuscitation. Additionally, equipment that is appropriately sized to resuscitate infants of all gestational ages should be available in all delivering institutions, even if the institution does not care for preterm or intensive care infants. Along with the necessary skills, the practitioner should approach any resuscitation with a good comprehension of transitional physiology and adaptation, as well as an understanding of the infant's response to resuscitation. Resuscitation involves much more than possessing an ordered list of technical skills and having a resuscitation team; it requires excellent assessment skills and a grounded understanding of physiology.

Diverticula are small, bulging pouches that can form in the lining of your digestive system. They are found most often in the lower part of the large intestine (colon). Diverticula are common, especially after age 40, and seldom cause problems. Sometimes, however, one or more of the pouches become inflamed or infected. That condition is known as diverticulitis (die-vur-tik-yoo-LIE-tis). Diverticulitis can cause severe abdominal pain, fever, nausea and a marked change in your bowel habits. Mild diverticulitis can be treated with rest, changes in your diet and antibiotics. Severe or recurring diverticulitis may require surgery.

The most frequent incision utilized to open the abdomen for liver surgery is called a chevron incision. In this incision a cut is made on the abdomen below the rib cage. The cut starts under the armpit below the ribs on the right side of the abdomen and continues all the way across the abdomen to the opposite arm pit thereby the whole width of the abdomen is cut to provide access to the liver. The average length of the incision is approximately 24 to 30 inches. This is one of the longest incisions is utilized in abdominal surgery. The incision is frequently associated with significant discomfort after the surgery and in some patients the discomfort can continue for many months, particularly when some of the nerves in the abdominal wall have been cut during the surgery. Laparoscopic surgery provides advantages over open surgery for the liver since the chevron incision is completely avoided and the surgery is performed through tiny incisions. As a consequence the duration of stay in hospital, the amount and duration of post operative discomfort, and the length of recovery is much shorter after the laparoscopic procedure compared to open surgery

A Texas baby, born with part of her heart outside her body ( Ectopia Cordis) , defies the odds and leaves hospital following a successful surgery.

Dilated cardiomyopathy is a disease of the heart muscle, usually starting in your heart's main pumping chamber (left ventricle). The ventricle stretches and thins (dilates) and can't pump blood as well as a healthy heart can. The term "cardiomyopathy" is a general term that refers to the abnormality of the heart muscle itself. Dilated cardiomyopathy might not cause symptoms, but for some people it can be life-threatening. A common cause of heart failure — the heart's inability to supply the body with enough blood — dilated cardiomyopathy can also contribute to irregular heartbeats (arrhythmias), blood clots or sudden death. The condition affects people of all ages, including infants and children, but is most common in men ages 20 to 60.
