Abstract: OBJECTIVE:To assess the effect of transnasal humidified rapid-insufflation ventilatory exchange (THRIVE) on gastric insufflation during general anesthesia induction in obese patients.
METHODS:Ninety obese patients (BMI 30-39.9 kg/m
RESULTS:The incidence of gastric insufflation was significantly higher in Group M and Group M+T than in Group T (
CONCLUSIONS:Ultrasound monitoring of the comet tail sign and the changes of CSA-GA in the gastric antrum is feasible and reliable for detecting gastrointestinal airflow, and in obese patients, the application of THRIVE for induction of anesthesia can ensure the oxygenation level without further increasing gastric insufflation.
