Appendectomy Clinical Trial
Official title:
Ultrasound Assessment of Gastric Content and Gastric Volume Before Crash Induction for Appendectomy
Performing anesthetic induction for appendicectomy has two main risks : first aspiraion of
gastric content causing pneumonia. Otherwise, anaphylactic risk to drugs used during
anesthetic induction. Indeed, the guidelines recommend an anesthetic induction protocol
qualified "full stomach" whatever the patient and the preoperative fasting period are. This
protocol provides the use of fast-acting neuromuscular blocking agents (succinylcholine or
rocuronium). However, these neuromuscular blocking agents are ten times more at allergic
risk than others. Ultrasound assessment of gastric content before rapid sequence induction
of anesthesia is a reproducible, non-invasive, inexpensive and quickly achievable bedside
technique. Furthermore, the correlations between gastric volume and risk of a full stomach
and also between the cross-section antral area (CSA) and the risk of a full stomach have
been validated on several patient cohorts. We formulate the hypothesis that the achievement
of a gastric ultrasound before anesthetic induction for appendectomy could allow to identify
"full stomach" patients who actually justify rapid sequence induction of anesthesia with
exposure to fast-acting neuromuscular blocking agents that implies.
Primary endpoint is to determine te percentage of patients who have a gastric content before
appendectomy. Secondary endpoint is to determine the incidenc of aspiration pneumonia and
anaphylactic shock. Another secondary endpoint is to determine the percentage of patient
with gastric content with the antral grading system (Perlas method) and to evaluate the
concordance between this methode and the cross-section antral area.
