OBJECTIVE
To determine whether short time variation (STV) of fetal heart beat correlates with scalp pH measurements during labor.
PATIENTS AND METHODS
From 1279 deliveries, 197 women had at least one fetal scalp pH measurement. Using the CTG-Player, STVs were calculated from the electronically saved cardiotocography (CTG) traces and related to the fetal scalp pH measurements.
RESULTS
There was no correlation between STV and fetal scalp pH measurements (r=-0.0592).
CONCLUSIONS
Fetal STV is an important parameter with high sensitivity for antenatal fetal acidosis. This study shows that STV calculations do not correlate with fetal scalp pH measurements during labor, hence are not helpful in identifying fetal acidosis.
目的
确定胎儿心跳的短期变异（STV）是否与分娩期间头皮 pH 值测量相关。
患者和方法
在 1279 次分娩中，有 197 名女性至少进行了一次胎儿头皮 pH 值测量。使用 CTG-Player，从电子保存的胎心监护图（CTG）迹线上计算 STV，并将其与胎儿头皮 pH 值测量相关联。
结果
STV 与胎儿头皮 pH 值测量之间没有相关性（r=-0.0592）。
结论
胎儿 STV 是产前酸中毒具有高灵敏度的重要参数。本研究表明，STV 计算值与分娩期间的胎儿头皮 pH 值测量不相关，因此对识别胎儿酸中毒没有帮助。
