Active clinical trials for "Respiratory Aspiration of Gastric Contents"

Pulmonary aspiration of gastric contents is a complication causing significant morbidity and mortality related to anesthesia. Ultrasound examination of the gastric antrum allows the detection of preoperative gastric contents contributing to the preoperative assessment of pulmonary aspiration risk. In particular, this examination is based on the qualitative analysis of gastric contents performed in the supine and in the right lateral decubitus, using a qualitative score which makes it possible to discriminate a low liquid content of a large liquid volume. This score has been described in patients and volunteers installed on a bed without elevation of the upper section of the bed. However, in several studies, this qualitative score has been achieved in the 45° semirecumbent position, which may have affected the diagnostic performance of the examination thus performed, as suggested by the results of a study recently conducted by the investigating team. This study therefore aims to compare the diagnostic performance of the qualitative analysis of the gastric antrum performed in the supine and the right lateral decubitus for the diagnosis of gastric volumes higher than 50 ml and 100 ml, according to the bed angle: 45 ° elevation or no elevation of the upper section of the bed.

The aim of this study is to compare the residual gastric volumes in non-labouring parturients prior to elective Caesarean delivery when fully fasted as per European Society of Anaesthesia pre-operative fasting guidelines against the 'Sip Til Send' fasting guideline via a paired cohort study. The primary hypothesis is that 'Sip Til Send' would be non-inferior to standard fasting at minimising the residual gastric volume prior to surgery.

This study is designed to evaluate the occurrence of gastric insufflation and the critical volume of the stomach after three different modes of positive pressure ventilation during induction (Manual-controlled, volume-controlled and pressure-controlled ventilation)

Point-of-care gastric ultrasound will be used to measure stomach contents postoperative in patients who underwent colorectal surgery. Stomach volume and status (empty or full) will be compared retrospectively to the standard clinical criteria for diet advancement to determine if stomach volume via ultrasound is associated with successful diet advancement, nausea/vomiting, nasogastric tube replacement, length of stay, and other clinical outcomes. Clinicians performing clinical care will be blinded to the ultrasound exam results.
