Preoperative Ultrasound Evaluation of Gastric Contents in Voluntary Termination of Pregnancy During the First Trimester

Centre Hospitalier Régional Metz-Thionville304 enrolled

Overview

This is an observational, prospective, monocentric, diagnostic study aiming to evaluate the diagnostic properties of the presence of nausea-vomiting in predicting the existence of gastric contents in preoperative surgical abortion.

Most surgical abortions are performed under general anaesthesia. Inhalation of gastric contents is one of the main complications of general anesthesia, in terms of frequency and severity. Patients in the 1st trimester of pregnancy are frequently subject to nausea and vomiting, even on an empty stomach. The presence of nausea and vomiting prior to surgery means that the anesthetic protocol needs to be modified, as there is a greater risk of complications, particularly allergic ones. Preoperative gastric ultrasound is recognized for its ability to predict the risk of gastric inhalation during anesthesia. It is a non-irradiating, non-invasive, painless and rapid examination. There are no data on the association between gestational nausea and vomiting and the risk of inhalation in the context of preoperative fasting. There are no data on the gastric volume of patients in the 1st trimester of pregnancy with or without nausea. Does gestational nausea and vomiting represent an anesthetic risk of gastric inhalation?
