生物测力仪(TOCO应变仪技术)提供宫缩频率和分娩收缩的大致持续时间，但经常出现信号丢失，需要护士重新定位，在肥胖患者中可能失败。另一种有创宫内压力导管(IUPC)更可靠，增加了收缩压力信息，但需要破裂的胎膜，并引入了很小的感染和早剥风险。子宫电描记术(EHG)通过放置在产妇腹部的电极报告子宫的电活动。这项研究比较了三种同时检测分娩妇女宫缩的方法。经同意后，对分娩妇女同时进行TOCO、EHG和IUPC监测。EHG的收缩曲线是实时生成的，所有三条曲线都以电子方式存储。收缩检测算法被用来比较不同方法的频率和时序。73名受试者参加了这项研究；14人因一个或多个设备的硬件故障(12人)或数据收集持续时间不足(2人)而被排除在外。与黄金标准宫内节育器相比，EHG在收缩一致性指数(CCI)方面明显优于TOCO。EHG的平均CCI为0.88±0.17，而TOCO的CCI为0.69±0.27(p<；0.0001)。与TOCO相比，EHG没有受到肥胖的显著影响。TOCO与黄金标准的IUPC相关性不好，在肥胖患者中失败的频率更高。EHG提供了一种可靠的、非侵入性的替代方案，不受身体习惯的影响。
Tocodynamometry (Toco—strain gauge technology) provides contraction frequency and approximate duration of labor contractions, but suffers frequent signal dropout necessitating re-positioning by a nurse, and may fail in obese patients. The alternative invasive intrauterine pressure catheter (IUPC) is more reliable and adds contraction pressure information, but requires ruptured membranes and introduces small risks of infection and abruption. Electrohysterography (EHG) reports the electrical activity of the uterus through electrodes placed on the maternal abdomen. This study compared all three methods of contraction detection simultaneously in laboring women. Upon consent, laboring women were monitored simultaneously with Toco, EHG, and IUPC. Contraction curves were generated in real-time for the EHG and all three curves were stored electronically. A contraction detection algorithm was used to compare frequency and timing between methods. Seventy-three subjects were enrolled in the study; 14 were excluded due to hardware failure of one or more of the devices (12) or inadequate data collection duration(2). In comparison with the gold-standard IUPC, EHG performed significantly better than Toco with regard to Contractions Consistency Index (CCI). The mean CCI for EHG was 0.88 ± 0.17 compared to 0.69 ± 0.27 for Toco (p<.0001). In contrast to Toco, EHG was not significantly affected by obesity. Toco does not correlate well with the gold-standard IUPC and fails more frequently in obese patients. EHG provides a reliable non-invasive alternative regardless of body habitus.
