  Ultrasonography use for the evaluation of gastric contents

Study Details

Perioperative aspiration of gastric contents is a rare but serious adverse event. The risk of aspiration can be estimated by perioperative evaluation of stomach contents with ultrasound using a validated technique and scoring system. A lack of knowledge or familiarity is frequently cited by anesthesia providers as a rationale for not performing perioperative ultrasound assessments. The purpose of this study is to determine whether novice ultrasonography users (medical students, undergraduates, or inexperienced anesthesiologists) can be effectively taught a technique to evaluate stomach contents as compared to experts in ultrasonography.

Arms

• Other: Healthy adult volunteers
  Novice ultrasonographers will be taught to assess gastric contents with a short and simple educational program. Each novice will assess the gastric contents of 3 healthy adult volunteers using the clinical algorithm for gastric ultrasound and aspiration risk assessment - giving an antral grade for each subject (a score of 0-2). Each novice ultrasound assessment will be video recorded. In the weeks following this evaluation, expert ultrasonographers will observe each video and give their own scores for each subject using the antral grading system.
• Other: Pediatric patients
  Novice ultrasonographers will be taught to assess gastric contents with a short and simple educational program. Each novice will assess the gastric contents of 3 pediatric patients undergoing surgery in the preoperative area or the in-patient unit using the clinical algorithm for gastric ultrasound and aspiration risk assessment - giving an antral grade for each subject (a score of 0-2). Each novice ultrasound assessment will be video recorded. In the weeks following this evaluation, expert ultrasonographers will observe each video and give their own scores for each subject using the antral grading system.

Primary Outcome Measure

Novice vs Expert Ultrasonographers Gastric Evaluation [ Time Frame: Novice ultrasonographers: for pediatric patients - after anesthesia induction and before the procedure start, for healthy volunteers - hours following signing the consent form. Expert ultrasonographers: weeks following the initial evaluation by novices. ]
