Changes in heart rate variability (HRV) and electroencephalographic (EEG) background are promising tools for risk stratification and outcome prediction in children seen in the Emergency Department (ED). Novel monitoring technologies offer an opportunity for determining the clinical value of these physiologic variables, however, studies evaluating these measurements obtained in the Pediatric ED are sparse. The current study used a single center, prospective, observational cohort study of HRV and EEG as early predictors of outcome in children with acute trauma. ECG and HRV data were successfully collected in 167 subjects and simultaneous collection of ECG and EEG data using a wireless monitoring device was piloted in 17 patients with 15 patients having EEG data rated as appropriate for clinical interpretation. The mean time from ED arrival to ECG and EEG recording start was 7.5 (SD 11.6) and 34.5 (SD 15.5) minutes, respectively. The mean time required for EEG electrode placement was 9.3 min (SD 5.8 min). Results showed recording early HRV and EEG is feasible in children with acute injury seen in the ED. This study suggests that high consent rates are possible with the adequate research infrastructure and physiologic variables may offer an early, non-invasive marker for injury stratification and prognosis in children.

心率变异性 (HRV) 和脑电图 (EEG) 背景的变化是急诊科 (ED) 儿童风险分层和结果预测的有希望的工具。新的监测技术为确定这些生理变量的临床价值提供了机会，但是，评估在儿科 ED 中获得的这些测量值的研究很少。目前的研究使用 HRV 和 EEG 的单中心、前瞻性、观察性队列研究作为急性创伤儿童预后的早期预测指标。成功收集了 167 名受试者的心电图和 HRV 数据，并在 17 名患者中试行了使用无线监测设备同时收集心电图和脑电图数据，其中 15 名患者的脑电图数据被评为适合临床解释。从 ED 到达 ECG 和 EEG 记录开始的平均时间分别为 7.5 (SD 11.6) 和 34.5 (SD 15.5) 分钟。EEG 电极放置所需的平均时间为 9.3 分钟（标准差 5.8 分钟）。结果表明记录早期 HRV 和脑电图对于急诊室中出现急性损伤的儿童是可行的。这项研究表明，在足够的研究基础设施和生理变量下，高同意率是可能的，并且可以为儿童的损伤分层和预后提供早期、非侵入性的标志物。
