Study Overview
Brief Summary
Pulmonary aspiration of gastric contents is one of the most dreaded complications of anesthesia. It predisposes the patients to lethal consequences secondary to lung injury from aspirated particulate matter, acid, and bacteria. Aspiration pneumonitis or Mendelson’s syndrome is a condition that occurs as a result of aspiration of very acidic sterile gastric fluid of volume >25 ml and pH <2.5 . Hence, preoperative estimation of gastric content volume with ultrasound remains a very valuable asset in assessing and reducing the perioperative risk of pulmonary aspiration.
A prospective, randomized, interventional study will be conducted on 315 ASA I-IV adult patients undergoing endoscopic procedures under mild sedation. Gastric content volume will be first assessed preoperatively with Gastric ultrasonography (GUS). Later, gastric contents will be suctioned by the endoscopist under direct vision. Data collected will be statistically correlated and analysed.
Our aim of study and primary outcome will be to evaluate the accuracy of volume estimated by ultrasonography and its quantitative correlation with gastric contents suctioned via endoscopy. The secondary outcome will be to correlate the residual gastric volume with the duration of fasting for liquids, semisolids and solids.
