1989年4月至1991年4月施行胎心监护共503例,发现跳跃型胎心监护图20例(孕期18例,产时2例).根据图型情况分为Ⅰ型(完全跳跃型),Ⅱ型(频发跳跃型),Ⅲ型(间发跳跃型).该类图型提示特殊类型的脐带因素存在,由于脐带缠绕胎儿肢体或在羊水过少时脐带被挤在胎儿肢体与躯干之间,胎儿肢体的运动干扰脐带血流可能是导致基线变异增加的原因,然而此种对脐带血流的干扰常不致完全阻断,故胎儿预后好.本文根据图型类别及胎龄情况提出了处理原则.
From April 1989 to April 1991, a total of 503 cases of fetal heart rate monitoring were performed, and 20 cases of skip type fetal heart monitoring chart (18 cases during pregnancy and 2 cases during delivery) were classified according to the pattern type Ⅰ (complete jumping type) , Type II (frequent jumping type), type III (intermittent jumping type) .This type of graph suggests that there are special types of umbilical cord factors, as the umbilical cord wrapping around the fetus or in the case of oligohydramnios is squeezed in the fetal limbs and trunk Interference of fetal limb movement with umbilical cord blood flow may be the reason for the increase of baseline variability, however, the interference of umbilical cord blood flow will not be completely blocked, so the fetus has a good prognosis.This article proposed according to the type of pictorial and gestational age Principles of treatment.
