Abstract

Since Saling's work in 1961, many investigators have attempted to perfect methods to detect fetal acidosis during labor. A system for continuous tissue pH monitoring of the fetus is evaluated in this study of 59 patients. There was poor correlation of tissue pH values and capillary scalp pH values in 19 cases (r = 0.487), and no significant correlation of tissue pH values to the outcome measurements of Apgar scores and cord gas levels. The benefits realized were those of monitoring the trend of tissue pH over time. We believe that a continuous pH monitoring system offers several advantages over intermittent fetal scalp sampling. Further refinement of the technology employed may offer such a system in the future.

摘要

自1961年萨林的研究工作以来，许多研究人员一直试图完善分娩期间检测胎儿酸中毒的方法。本研究对59例患者评估了一种用于连续监测胎儿组织pH值的系统。19例患者的组织pH值与头皮毛细血管pH值之间相关性较差（r = 0.487），且组织pH值与阿氏评分和脐带血气水平等结局指标之间无显著相关性。所实现的益处在于监测组织pH值随时间的变化趋势。我们认为，与间歇性胎儿头皮采样相比，连续pH监测系统具有多个优势。未来，对所采用技术的进一步改进可能会提供这样一种系统。
