Ultrasonic study of amnioinfusion. A report of two cases.

Two patients had amnioinfusion with subsequent improvement in fetal heart rate (FHR) patterns. Ultrasound in case 1 showed a pocket of saline around the umbilical cord and improved FHR. Case 2 likewise had an improvement in the FHR without ultrasonic evidence of a protective pocket of fluid. Case 2 actually had a tight true knot in the cord, which explained the abnormal FHR pattern. Amnioinfusion can form a protective pocket of fluid around the umbilical cord in cases of severe oligohydramnios, although in our experience its success rate is low and unpredictable.

Recording maternal vaginal apex pulse.

A photoelectric plethysmographic probe, which emits and receives a low-voltage infrared light was placed in the vaginal apex of 122 high-risk pregnant women. The normal pulse form of the upper vagina does not have a diastolic notch. A study was undertaken to determine whether the vaginal apex pulse recording equals the accuracy, sensitivity, and specificity of the uterine artery Doppler velocimetry, and whether abnormal uterine artery wave forms are fixed. The vaginal apex recordings had greater sensitivity to abnormal outcome than did the uterine artery Doppler technique. The vaginal apex pulse height decreased significantly in a majority of the women undergoing elective cesarean section and during uterine contractions. In patients with abnormal wave forms (diastolic notches) and treated with either terbutaline sulfate or magnesium sulfate, the diastolic notch disappeared in eight out of 14 cases.
