Background: Pediatric emergency medicine (PEM) physicians have variably incorporated point-of-care ultrasound (POCUS) into their practice. Prior guidelines describe the scope of POCUS practice for PEM physicians; however, consensus does not yet exist about which applications should be prioritized and taught as fundamental skills for PEM trainees. Members of the PEM POCUS Network (P2Network) conducted a consensusbuilding process to determine which applications to incorporate into PEM fellowship training.Methods: A multinational group of experts in PEM POCUS was recruited from the P2Network and greater PEM POCUS community if they met the following criteria: performed over 1,000 POCUS scans and had at least 3 years of experience teaching POCUS to PEM fellows, were a local academic POCUS leader, or completed a formal PEM POCUS fellowship. Experts rated 60 possible PEM POCUS applications for their importance to include as part of a PEM fellowship curriculum using a modified Delphi consensus-building technique.Results: In round 1, 66 of 92 (72%) participants responded to an e-mail survey of which 48 met expert criteria and completed the survey. Consensus was reached to include 18 items in a PEM fellowship curriculum and to exclude two items. The 40 remaining items and seven additional items were considered in round 2. Thirty-seven of 48 (77%) experts completed round 2 reaching consensus to include three more items and exclude five. The remaining 39 items did not reach consensus for inclusion or exclusion.Conclusion: Experts reached consensus on 21 core POCUS applications to include in PEM fellowship curricula. P oint-of-care ultrasound (POCUS) has been established in the practice of emergency medicine for over two decades. 1,2 More recently, its use has expanded into the practice of pediatric emergency medicine (PEM). 3 Most PEM fellowship programs now offer formal ultrasound training to their fellows and incorporate POCUS into the care of the pediatric patient. 4,5 In
Objectives:The objective was to use gastric point-of-care ultrasound (POCUS) to assess gastric contents and volume, summarize the prevalence of "full stomach," and explore the relationship between fasting time and gastric contents at the time of procedural sedation.Methods: This was a prospective study of patients aged 2 to 17 years fasting prior to procedural sedation. A single sonographer scanned each patient's gastric antrum in two positions: supine with the upper body elevated and right lateral decubitus (RLD). Gastric content (empty, liquid, or solid) was noted, and the gastric volume (mL/ kg) was estimated from antral cross-sectional area (CSA). "Full stomach" was defined as any solid content or >1.2 mL/kg of liquid gastric content.Results: We enrolled 116 subjects, with a median fasting time of 5.8 hours. Of the 107 with evaluable images, 74 patients, 69% (95% confidence interval [CI] = 60%-77%), were categorized as having a full stomach. Each hour of fasting was associated with lower odds (odds ratio = 0.79, 95% CI = 0.65-0) of a full stomach. However, the knowledge of fasting time alone provides little ability to discriminate between risk groups (C-index = 0.66).Conclusions: Gastric POCUS classified many patients as having a full stomach at the time of expected procedural sedation, despite prolonged fasting times. These findings may inform risk-benefit considerations when planning the timing and medication choice for procedural sedation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
