POCUS gástrico, una herramienta emergente en la valoración del ayuno perioperatorio: revisión narrativa

Abstract

Pulmonary aspiration during anesthetic induction is a serious adverse event that can lead to catastrophic consequences for the patient, including death. To date, the assessment of preoperative fasting has been evaluated with the history using the times recommended by clinical guidelines. This assessment is not objective since the presence or absence of gastric contents cannot be assured. The implementation of bedside gastric ultrasound in a complementary manner prior to anesthetic induction is an objective, simple and rapid tool that helps stratify risk in decision-making. The objective of this review is to summarize the existing literature on gastric POCUS in the assessment of preoperative fasting relevant to anesthetic practice. To this end, a bibliographic review has been carried out in the main databases Pubmed and Embase from 2014 to 2024.
