Abdominal compartment syndrome
نویسنده
چکیده
Various systems are involved in this syndrome. First, the increased intra-abdominal pressure is transmitted to the pleural space so that lung compliance decreases. Hypoventilation and alteration of ventilation/perfusion distribution lead to hypoxemia and hypercapnia. When mechanical ventilation is applied, very high inspiratory pressures are often required to deliver tidal volume. Second, the combined increase in abdominal pressure and pleural pressure leads to a decrease in venous return, direct compression of the heart, and increased afterload (especially in the right ventricle). Third, perfusion to the intra-abdominal organs can be critically reduced by the combined effects of the decreased cardiac output, increased interstitial pressure, and increased outflow pressure. This can lead to oliguria and renal failure. Splanchnic ischemia can also occur as reflected by a decreased mucosal pH [1,2] , decreased liver metabolism [3], and bacterial translocation [4]. In addition, perfusion of the abdominal wall may be decreased, so that wound healing may be impaired. Finally, intracranial pressure may also be increased due to the decrease in cerebral venous return and increased venous pressure.

Comparison of Intra-abdominal Pressure Measurement and Physical Exam for Diagnosis of Surgery Indication in Patients with Abdominal Compartment Syndrome due to Blunt Trauma
Background & Aims: Increase in abdominal pressure can lead to the so-called intra–abdominal compartment syndrome (ACS) that is often observed during the first 24 hours after sever abdominal trauma and surgery. Measurement of the intra abdominal pressure through the bladder as a non-invasive measurement can provide a quick and accurate assessment of abdominal pressure changes. This study was per...

متن کاملAbdominal compartment syndrome in children.
Abdominal compartment syndrome is defined as sustained intra-abdominal pressure greater than 20 mm Hg (with or without abdominal perfusion pressure <60 mm Hg) associated with new organ failure or dysfunction. The syndrome is associated with 90% to 100% mortality if not recognized and treated in a timely manner. Nurses are responsible for accurately measuring intra-abdominal pressure in children...
متن کاملAbdominal Compartment Syndrome
Abdominal compartment syndrome is a potentially lethal condition caused by any event that produces intra-abdominal hypertension; the most common cause is blunt abdominal trauma. Increasing intraabdominal pressure causes progressive hypoperfusion and ischemia of the intestines and other peritoneal and retroperitoneal structures. Pathophysiological effects include release of cytokines, formation ...
متن کاملDevelopment of a Rodent Model for the Study of Abdominal Compartment Syndrome
Background: The clinical pertinence of increased abdominal pressures has gained attention with the high correlation with damage control surgery in trauma. Increasing abdominal compartmental pressures have been associated with an increased rate of multiple organ dysfunction in several studies. This led to the 2004 consensus conference of the World Society on Abdominal Compartment Syndrome (WSACS...
