胎心率监护的内测法,筒称胎心率内监护,又称直接法,为侵入性的方法,通过插入官腔导管,胎儿头皮放置电极,可观察产时胎心率与宫缩的关系,描绘出胎心宫缩图(CTG),从而分析胎儿宫内情况。此方法在国外已相当普遍,国内近年来已有个别报道。本文回顾分析了1986年1～12月我院使用山监护的情况,并探讨内测法可能发生的并发症和防治方法。资料和方法 1986年1～12月,我院使用胎心率内监护共32例。使用仪器为美国Corometrics公司115型胎儿监护仪,于宫口开张2～3cm左右,放置螺旋式头皮电极和宫腔导管(以下简称为整套内监护),共12例;宫口大于5cm者,单置头皮电极,宫缩描绘采用外测法探头配合,共20例,现将上述资料进行回顾性分析。
Fetal heart rate monitoring of the internal test method, tube said Fetal heart rate monitoring, also known as direct method, as an invasive method, through the insertion of the bureaucratic catheter, the fetal scalp placed electrodes can be observed during labor fetal heart rate and contractions relationship , Depicting fetal heart contraction (CTG), in order to analyze intrauterine conditions. This method has been quite common in foreign countries and has been reported individually in recent years in China. This article retrospectively analyzed the use of mountain guardianship in our hospital from January to December 1986, and discussed the possible complications and prevention methods of internal control test. Materials and Methods January 1986 to December, our hospital used fetal heart rate monitoring in 32 cases. Instruments used for the United States Corometrics 115 fetal monitor, opened in the mouth about 2 ~ 3cm, placed spiral scalp electrodes and uterine catheters (hereinafter referred to as the whole package of custody), a total of 12 cases; cervix greater than 5cm who single Set scalp electrodes, uterine contraction using external probe with a total of 20 cases, the above data are retrospectively analyzed.
