Objective To assess feasibility of transcutaneous electromyography of the diaphragm (dEMG) as a monitoring tool for vital signs and diaphragm activity in the delivery room (DR). Design Prospective observational study. Setting Delivery room. Patients Newborn infants requiring respiratory stabilisation after birth. Interventions In addition to pulse oximetry (PO) and ECG, dEMG was measured with skin electrodes for 30 min after birth. Outcome measures We assessed signal quality of dEMG and ECG recording, agreement between heart rate (HR) measured by dEMG and ECG or PO, time between sensor application and first HR read-out and agreement between respiratory rate (RR) measured with dEMG and ECG, compared with airway flow. Furthermore, we analysed peak, tonic and amplitude diaphragmatic activity from the dEMG-based respiratory waveform. Results Thirty-three infants (gestational age: 31.7±2.8 weeks, birth weight: 1525±661 g) were included. 18%±14% and 22%±21% of dEMG and ECG data showed poor quality, respectively. Monitoring HR with dEMG was fast (median 10 (IQR 10–11) s) and accurate (intraclass correlation coefficient (ICC) 0.92 and 0.82 compared with ECG and PO, respectively). RR monitoring with dEMG showed moderate (ICC 0.49) and ECG low (ICC 0.25) agreement with airway flow. Diaphragm activity started high with a decreasing trend in the first 15 min and subsequent stabilisation. Conclusion Monitoring vital signs with dEMG in the DR is feasible and fast. Diaphragm activity can be detected and described with dEMG, making dEMG promising for future DR studies. Limited data are available on reasonable request. Unpublished data of the measurements in this cohort are only accessible to the authors of the paper. It is saved in a locked database.

使用经皮肌电图在产房进行心肺监测

目的评估经皮膈肌肌电图（dEMG）作为产房（DR）生命体征和膈肌活动监测工具的可行性。设计前瞻性观察研究。设置产房。患者 出生后需要呼吸稳定的新生儿。干预 除了脉搏血氧饱和度 (PO) 和 ECG 之外，在出生后 30 分钟内还使用皮肤电极测量 dEMG。结果测量 我们评估了 dEMG 和 ECG 记录的信号质量、dEMG 和 ECG 或 PO 测量的心率 (HR) 之间的一致性、传感器应用和第一次 HR 读数之间的时间以及使用 dEMG 和 ECG 测量的呼吸率 (RR) 之间的一致性，与气道流量相比。此外，我们分析了基于 dEMG 的呼吸波形的峰值、强直和振幅膈肌活动。结果纳入33名婴儿（胎龄：31.7±2.8周，出生体重：1525±661 g）。分别有 18%±14% 和 22%±21% 的 dEMG 和 ECG 数据显示质量较差。使用 dEMG 监测 HR 快速（中位数 10 (IQR 10-11) s）且准确（与 ECG 和 PO 相比，组内相关系数 (ICC) 分别为 0.92 和 0.82）。使用 dEMG 进行的 RR 监测显示与气道流量的中等 (ICC 0.49) 和 ECG 低 (ICC 0.25) 一致性。隔膜活性开始高，前 15 分钟呈下降趋势，随后趋于稳定。结论 在 DR 中使用 dEMG 监测生命体征是可行且快速的。可以使用 dEMG 检测和描述膈肌活动，使 dEMG 有望用于未来的 DR 研究。可应合理要求提供有限数据。该队列中未发表的测量数据仅供论文作者访问。它保存在锁定的数据库中。
