Lloyd-Davies Position
Lloyd-Davies position is a medical term referring to a common position for surgical procedures involving the pelvis and lower abdomen. The majority of colorectal and pelvic surgery is conducted with the patient in the Lloyd-Davies position. It was popularised for these procedures by Oswald Lloyd-Davies working at St Marks Hospital London. It is derived from the Trendelenburg position but with the legs abducted to allow access to the perineum. The basic angle is a 30-degree Trendelenburg with the hips flexed at 15 degrees; this can be adjusted with leg supports. Advantages # The position gives good exposure and may minimize pressure area damage in longer surgeries. # It has fewer neuropathological side effects compared with other positions, notably lithotomy position where the hips are almost fully flexed. Disadvantages # Uncommonly it can precipitate compartment syndrome in muscles of calves after 5 or more hours of surgery.http://journals.lww.com/anesthesiology/fulltext/199 ...

Trendelenburg Position
In the Trendelenburg position, the body is lain supine, or flat on the back on a 15–30 degree incline with the feet elevated above the head. The reverse Trendelenburg position, similarly, places the body supine on an incline but with the head now being elevated. The Trendelenburg position is used in surgery, especially of the abdomen and genitourinary system. It allows better access to the pelvic organs as gravity pulls the intra-abdominal organs away from the pelvis. Evidence does not support its use in hypovolaemic shock, with concerns for negative effects on the lungs and brain. The position was named for the German surgeon Friedrich Trendelenburg (1844–1924). Current uses *The Trendelenburg position can be used to treat a venous air embolism by placing the right ventricular outflow tract inferior to the right ventricular cavity, causing the air to migrate superiorly into a position within the right ventricle from which air is less likely to embolise.

Lithotomy Position
The lithotomy position is a common position for surgical procedures and medical examinations involving the pelvis and lower abdomen, as well as a common position for childbirth in Western nations. The lithotomy position involves the positioning of an individual's feet above or at the same level as the hips (often in stirrups), with the perineum positioned at the edge of an examination table. References to the position have been found in some of the oldest known medical documents including versions of the Hippocratic oath (see lithotomy); the position is named after the ancient surgical procedure for removing kidney stones and bladder stones via the perineum. The position is perhaps most recognizable as the 'often used' position for childbirth: the patient is laid on the back with knees bent, positioned above the hips, and spread apart through the use of stirrups. The position is frequently used and has many obvious benefits from the doctor's perspective. Most notably the position ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compartment Syndrome
Compartment syndrome is a condition in which increased pressure within one of the body's anatomical compartments results in insufficient blood supply to tissue within that space. There are two main types: acute and chronic. Compartments of the leg or arm are most commonly involved. Symptoms of acute compartment syndrome (ACS) can include severe pain, poor pulses, decreased ability to move, numbness, or a pale color of the affected limb. It is most commonly due to physical trauma such as a bone fracture (up to 75% of cases) or crush injury, but it can also be caused by acute exertion during sport. It can also occur after blood flow returns following a period of poor blood flow. Diagnosis is generally based upon a person's symptoms and may be supported by measurement of intracompartmental pressure before, during, and after activity. Normal compartment pressure should be within 12-18 mmHg; anything greater than that is considered abnormal and would need treatment. Treatment i ...
