- NG tube placement with known varices: In a study of 75 patients with documented esophageal varices, significant coagulopathies, and a high incidence of previous upper gastrointestinal bleeding, no patient developed gastrointestinal hemorrhage as a result of blind NG tube (or esophageal stethoscope) placement
From the World Society of the Abdominal Compartment Syndrome:
- Abdominal compartment syndrome is defined as a sustained intraabdominal pressure (IAP)> 20 mmHg that is associated with new organ dysfunction/failure
The reference standard for intermittent IAP measurements is via the bladder with a maximal instillation volume of 25 mL of sterile saline, and should be measured at end-expiration in the supine position
