Bedside Ultrasound of Gastric Contents in Pediatric Populations
What this study is about
Perioperative aspiration of gastric contents is a rare but serious side effects. 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.
View original scientific description
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.

Primary outcome measures
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.
The gastric evaluation of novice and expert ultrasonographers will be compared based on a 3-point numerical evaluation.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
