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.

In medicine, the caloric reflex test is a test of the vestibulo-ocular reflex that involves irrigating cold or warm water or air into the external auditory canal.

An abscess is a collection of pus. Pus is a thick fluid that usually contains white blood cells, dead tissue and germs (bacteria). The usual cause of an abscess is an infection with bacteria. Certain bacteria are more likely to be 'pus-forming' as they make chemicals (toxins) that can damage the body's tissues.

Skin changes are among the most visible signs of aging. Evidence of increasing age includes wrinkles and sagging skin. Whitening or graying of the hair is another obvious sign of aging. Your skin does many things. It: Contains nerve receptors that allow you to feel touch, pain, and pressure Helps control fluid and electrolyte balance Helps control your body temperature Protects you from the environment Although skin has many layers, it can generally be divided into three main parts: The outer part (epidermis) contains skin cells, pigment, and proteins. The middle part (dermis) contains blood vessels, nerves, hair follicles, and oil glands. The dermis provides nutrients to the epidermis. The inner layer under the dermis (the subcutaneous layer) contains sweat glands, some hair follicles, blood vessels, and fat. Each layer also contains connective tissue with collagen fibers to give support and elastin fibers to provide flexibility and strength.

One of the criteria to determine brain death is the irreversible absence of cerebral and brainstem reflexes including pupillary, oculocephalic, oculovestibular (caloric), corneal, gag, sucking, swallowing, and extensor posturing. Some of the other criteria for determination of brain death include: 1. Absence of respiratory drive (apnea) off the ventilator for a duration that is sufficient to produce hypercarbic drive (usually 10 to 20 minutes to achieve pC02 of 50 to 60 mmHg) ( 2. Body temperature below 34 C (93.2 F) 3. EEG isoelectric for 30 minutes at maximal gain 4. Absence of cerebral circulation by Doppler or magnetic resonance angiography 5. At least 24 hours of observation in adults with anoxic-ischemic brain damage with a negative drug screen

Purpose: To evaluate the results of LASIK and IntraLASIK treatment in myopic patients with nystagmus. Methods: Eight patients with congenital nystagmus (16 eyes), from 23 to 49 years of age, underwent LASIK surgery. Corneal flaps were created using either the Hansatome microkeratome or the Intral...ase femtosecond laser. The ablations were performed with the Bausch & Lomb excimer laser with an active tracking system. In some patients, the eyes were fixated with forceps or a fixation ring during the laser ablation. Results: The refractive errors were corrected in all cases. There was no decentration or loss of best corrected visual acuity greater than 1 line. In 56% of the eyes, the post-operative uncorrected visual acuity was better than the best spectacle corrected-visual acuity (BSCVA). 62.5% of the eyes improved their BSCVA. The overall visual performance was improved in all the patients. One patient that did not not drive before become eligible to get a driver license after the surgery. Conclusions: Selected patients with myopia and congenital nystagmus may benefit from laser refractive surgery. Laser refractive surgery may be safely and accurately performed by using either the Hansatome microkeratome or the Intralase femtosecond laser and an active tracking system with or without mechanical fixation. Certain patients improve their BSCVA post-operatively.

Ophthalmoscopy - Eye Clinical Examination - OSCE - Dr Gill

Direct Ophthalmoscopy use of the eyes is a very challenging clinical skill, incorporating both the examiner's knowledge of the retina, but also understanding the use of the ophthalmoscope

In this clinical skills tutorial, we look at the use of the direct ophthalmoscope as part of an ophthalmic examination

it should be noted that in the ideal circumstances, the room lights will be dimmed during the examination, and dilating eye drops used to improve the visualisation of the fundus

Though most snakes aren't venomous, the ones with a deadly bite are so scary that many researchers think humans evolved to naturally fear the sinuous creatures. With good reason. In the video, two men milk the venom of a Russell's viper and then show what happens when one drop of that venom mixes with a glassful of human blood. It's terrifying.

The Hypertensive urgency must be distinguished from hypertensive emergency. Urgency is defined as severely elevated blood pressure (ie, systolic >220 mm Hg or diastolic >120 mm Hg) with no evidence of target organ damage.

Each month inside your ovaries, a group of eggs starts to grow in small, fluid-filled sacs called follicles. Eventually, one of the eggs erupts from the follicle (ovulation). It usually happens about 2 weeks before your next period. Hormones Rise After the egg leaves the follicle, the follicle develops into something called the corpus luteum. The corpus luteum releases a hormone that helps thicken the lining of your uterus, getting it ready for the egg. The Egg Travels to the Fallopian Tube After the egg is released, it moves into the Fallopian tube. It stays there for about 24 hours, waiting for a single sperm to fertilize it. All this happens, on average, about 2 weeks after your last period.

A liver abscess is a pus-filled mass inside the liver. Common causes are abdominal infections such as appendicitis or diverticulitis due to haematogenous spread through the portal vein. A pyogenic liver abscess (PLA) is a pocket of pus that forms in the liver in response to an infection or trauma. Pus is a fluid composed of white blood cells, dead cells, and bacteria that forms when your body fights off infection.Dec 11, 2015

each type of heart problem requires different treatment but may share similar warning signs. It is important to see your doctor so that you can receive a correct diagnosis and prompt treatment. Learn to recognize the symptoms that may signal heart disease. Call your doctor if you begin to have new symptoms or if they become more frequent or severe. Symptoms of Coronary Artery Disease The most common symptom of coronary artery disease is angina, or chest pain. Angina can be described as a discomfort, heaviness, pressure, aching, burning, fullness, squeezing, or painful feeling in your chest. It can be mistaken for indigestion or heartburn. Angina may also be felt in the shoulders, arms, neck, throat, jaw, or back. Other symptoms of coronary artery disease include: Shortness of breath Palpitations (irregular heart beats, or a "flip-flop" feeling in your chest) A faster heartbeat Weakness or dizziness Nausea Sweating

This video demonstrates Laparoscopic Cholecystectomy Fully Explained Skin-to-Skin Video with Near Infrared Cholangiography performed by Dr R K Mishra at World Laparoscopy Hospital. A laparoscopic cholecystectomy is a minimally invasive surgical procedure that involves removing the gallbladder. It is typically performed using small incisions in the abdomen, through which a laparoscope (a thin tube with a camera and light) and surgical instruments are inserted. The surgeon uses the laparoscope to visualize the inside of the abdomen and to guide the instruments in removing the gallbladder.

Near-infrared cholangiography is a technique that uses a special camera and fluorescent dye to visualize the bile ducts during surgery. The dye is injected into the cystic duct (the tube that connects the gallbladder to the bile ducts) and the camera detects the fluorescence emitted by the dye, allowing the surgeon to see the bile ducts more clearly.

The combination of laparoscopic cholecystectomy and near-infrared cholangiography has become a standard of care in many hospitals and surgical centers. It allows for a more precise and efficient surgery, reducing the risk of complications such as bile duct injury.

The use of indocyanine green (ICG) with near-infrared imaging during laparoscopic cholecystectomy has several advantages. Here are some of them:

Better visualization of the biliary anatomy: ICG with near-infrared imaging allows for better visualization of the biliary anatomy during surgery. This helps the surgeon identify important structures, such as the cystic duct and the common bile duct, and avoid injuring them.

Reduced risk of bile duct injury: With better visualization of the biliary anatomy, the risk of bile duct injury during surgery is reduced. Bile duct injury is a serious complication that can occur during laparoscopic cholecystectomy and can lead to long-term health problems.

Improved surgical precision: ICG with near-infrared imaging also improves surgical precision. The surgeon can better see the tissues and structures being operated on, which can help reduce the risk of bleeding and other complications.

Shorter operating time: The use of ICG with near-infrared imaging can shorten the operating time for laparoscopic cholecystectomy. This is because the surgeon can more quickly and accurately identify the biliary anatomy, which can help streamline the surgery.

Overall, the use of ICG with near-infrared imaging is a valuable tool in laparoscopic cholecystectomy that can improve surgical outcomes and reduce the risk of complications.

Like any surgical procedure, laparoscopic cholecystectomy (gallbladder removal) has potential complications. Here are some of the most common ones:

Bleeding: Bleeding during or after the surgery is a possible complication of laparoscopic cholecystectomy. Most cases are minor and can be easily controlled, but in rare cases, significant bleeding may require a blood transfusion or even additional surgery.

Infection: Any surgical procedure carries a risk of infection. After laparoscopic cholecystectomy, there is a risk of infection at the site of the incisions or within the abdomen. Symptoms may include fever, pain, redness, or drainage from the incision sites.

Bile leakage: In some cases, a small amount of bile may leak from the bile ducts into the abdominal cavity after gallbladder removal. This can cause abdominal pain, fever, and sometimes requires further surgery or treatment.

Injury to nearby organs: During the surgery, there is a small risk of unintentional injury to nearby organs such as the liver, intestines, or bile ducts. This can cause additional complications and may require further treatment.

Adverse reactions to anesthesia: As with any surgery requiring general anesthesia, there is a small risk of adverse reactions to the anesthesia, such as an allergic reaction, respiratory problems, or heart complications.

Most patients recover without complications following a laparoscopic cholecystectomy, but it is important to discuss any concerns or questions with your surgeon beforehand.
