IntroductionResuscitation guidelines emphasize minimal interruption of compressions during cardiopulmonary resuscitation. Point-of-care ultrasound (POCUS) enables the clinician to visualize cardiac contractility and central artery pulsatility. The apical 4-chamber (A4), subxiphoid (SX), and femoral artery views may be used when defibrillator pads or active compressions preclude parasternal cardiac views. We hypothesized that clinicians can rapidly obtain interpretable POCUS views in healthy children from the A4, SX, and femoral positions.MethodsA prospective study of pediatric emergency medicine providers in an urban academic hospital was performed. Stable patients of 12 years or younger were scanned. Sonologists were each allotted 10 seconds to acquire A4, SX, and femoral views. Two attempts at each view were allowed. The primary outcome was whether cardiac and femoral artery scans were interpretable for contractility and pulsatility, respectively. The secondary outcome was whether cardiac scans were interpretable for effusion or right ventricular strain. A POCUS expert reviewed scans to confirm interpretability.ResultsTwenty-two sonologists performed a total of 50 scans on 22 patients. A view that was interpretable for contractility was obtained on the first attempt in 86% of A4 and 94% of SX scans. A femoral view that was interpretable for pulsatility was obtained on the first attempt in 74% of scans. Expert review was concordant with sonologist interpretation.ConclusionsPediatric emergency medicine physicians can obtain interpretable cardiac and central artery views within 10 seconds most of the time. Point-of-care ultrasound has the potential to enhance care during pediatric resuscitation. Future studies on the impact of POCUS pulse checks in actual pediatric resuscitations should be performed.Copyright © 2022 Wolters Kluwer Health, Inc. All rights reserved.
