Physicians' subjectivity in evaluating oxytocin challenge tests.

Five physicians subspecializing in maternal-fetal medicine individually evaluated 50 oxytocin challenge tests (OCTs), of which 33 were originally read as positive. There was considerable disagreement among the study physicians (SPs) such that 2 SPs would agree, on the average, only 52% of the time on any one OCT. The SPs were also asked to evaluate fetal heart rate (FHR) reactivity patterns, if present. Again, there was great disagreement. When the majority (3 of 5 or more) of SPs agreed on the OCT result and/or reactivity, there was reasonable correlation with neonatal outcome, indicating the validity of the physiologic premise of the test. In particular, the presence or absence of FHR accelerations with fetal motion, regardless of the OCT reading, correlated extremely well with eventual neonatal outcome. This indicates that the most significant variable in antepartum FHR monitoring is the FHR acceleration pattern.

A simple test for predicting pregnancy-induced hypertension.

One hundred thirty-one nulliparous patients between 28 to 34 weeks' gestation with no known history of renal disease or hypertension were placed in the left lateral recumbent position and their blood pressures were taken once and recorded. They then turned to the supine position where another blood pressure was taken within 2 minutes and also recorded. All these patients were then followed routinely throught their pregnancy, labor, delivery, and postpartum period. Of those patients whose diastolic blood pressure during the modified "roll-over" test rose less than 15 mmHg, only 2 of 99 developed pregnancy-induced hypertension (PIH). Of those whose roll-over test showed an increase of more than 15 mmHg, 23 of 32 developed PIH (P less than .000000001). Of those whose blood pressure during the roll-over developed PIH(P less than .00000001). Also, 10 of 11 patients whose diastolic blood pressure increased more than 25 mmHg during the roll-over test developed PIH (P less than .000000001).

Childrens' distress during burn treatment is reduced by massage therapy.

Before dressing changes, 24 young children (mean age = 2.5 years) hospitalized for severe burns received standard dressing care or massage therapy in addition to standard dressing care. The massage therapy was conducted to body parts that were not burned. During the dressing change, the children who received massage therapy showed minimal distress behaviors and no increase in movement other than torso movement. In contrast, the children who did not receive massage therapy responded to the dressing change procedure with increased facial grimacing, torso movement, crying, leg movement and reaching out. Nurses also reported greater ease in completing the dressing change procedure for the children in the massage therapy group. These findings suggest that massage therapy attenuates young childrens' distress responses to aversive medical procedures and facilitates dressing changes.

Constant intravenous insulin infusion during labor and delivery in diabetes mellitus.

We treated 30 diabetic women (31 pregnancies) during the peripartum period with a continuous insulin infusion. A mean infusion rate of 1.0 micron/h maintained the mean plasma glucose concentration below 100 mg/dl in 84% of the patients; the plasma glucose concentration was below 100 mg/dl within an hour of delivery in 71% of the women. Mild hypoglycemia developed during the infusion in three women and after delivery in another patient. Only two infants of the diabetic mothers developed transient and asymptomatic hypoglycemia. We conclude that continuous insulin infusion is a practical, safe, and effective method for treating diabetic mothers during the peripartum period and suggest that this technique may decrease the frequency and severity of neonatal hypoglycemia.
