Intra- & Interrater Reliability of Quantitative Ultrasound Assessment of

Status Completed

Clinical Trial Summary

The presence of solid food or fluid residue in the stomach is always a major concern when patients require medical procedures under sedation or general anesthesia, due to the high risk of pulmonary aspiration of the stomach contents. This is especially important in emergency procedures, when a fasting period could not be observed. Pulmonary aspiration of gastric content is a serious perioperative complication of obstetric anesthesia, and it is associated with morbidity and mortality. Information from a bedside ultrasound assessment of the stomach may be a very useful resource to decide whether it's safe to proceed, cancel or delay a surgical procedure. The ultrasound assessment of the stomach content has shown to be very feasible and practical in non-pregnant patients. However, it has not been determined whether the competence reached by anesthesiologists in non-pregnant subjects can be transferred to the obstetric population, especially in term pregnant patients where it could be difficult to identify the stomach because of the presence of the gravid uterus. Although quantitative assessment of the gastric antrum cross-sectional area in terms of intra- and interrater reliability has been evaluated in non-pregnant adults, it remains to be evaluated in pregnant patients. Furthermore, it has not been determined whether the performance of novice operators is comparable to expert operators in the gastric quantitative assessment. This study aims to determine whether trained anesthesiologists can reliably assess the stomach content of pregnant patients by ultrasound, evaluating the inter- and intra-rater reliability of quantitative gastric ultrasound in term pregnant patients comparing anesthesiologists of different level of expertise. The investigators hypothesize a substantial to almost perfect agreement in the intra- and interrater reliability of the antral cross-sectional area among raters in term pregnant patients scheduled for elective cesarean delivery.

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
