UNASSIGNED: Patients presenting to the emergency department after a submersion event were eligible if a CXR was obtained as part of their care. Emergency medicine residents performed a lung POC ultrasound and provided a \"novice\" interpretation of \"normal\" or \"abnormal,\" which was independently reviewed by a blinded expert sonographer. Patients were contacted 2 weeks after presentation to assess for late sequela.
UNASSIGNED: A prospective convenience sample of 59 patients included 21 adults (36%) and 38 children (64%) enrolled over 17 months with a median age of 6. Twenty-four (41%) patients had abnormalities on CXR. Of these, 20 patients had a positive ultrasound per novice interpretation. Compared to CXR, ultrasound had an overall sensitivity of 83% and a specificity of 66% for detecting pulmonary edema in non-fatal drownings. Notably, out of 35 subjects with a negative CXR, there were 12 (34%) cases with a positive lung ultrasound, 10 of which required hospital admission.
UNASSIGNED: Lung POC ultrasound has a moderate sensitivity and specificity when performed by novice sonographers to detect pulmonary edema presenting to an ED setting after a non-fatal drowning event.
■如果作为护理的一部分获得了CXR,则在浸没事件后到急诊科就诊的患者符合资格。急诊医师进行了肺部POC超声检查,并提供了“新手”解释“正常”或“异常”,“这是由一名失明的超声专家独立审查的。就诊后2周联系患者以评估晚期后遗症。
■59名患者的前瞻性便利样本包括21名成人(36%)和38名儿童(64%),年龄超过17个月,中位年龄为6岁。24(41%)患者的CXR异常。其中,每个新手解释20例患者的超声检查结果为阳性。与CXR相比,在非致命性溺水中,超声检测肺水肿的总体敏感性为83%,特异性为66%.值得注意的是,在35名CXR阴性的受试者中,有12例(34%)肺部超声阳性,其中10人需要住院。
■在非致命性溺水事件发生后,由新手超声医师进行肺POC超声检查以检测ED设置的肺水肿时,肺POC超声具有中等的敏感性和特异性。
