The effect of membrane rupture on fetal heart rate in induced labour.

The influence of the state of the membranes on the fetal heart rate was studied in a group of twelve women whose membranes were electively ruptured for oxytocin induction of labour. The results have been compared with a group of eight women of similar gestation and parity whose membranes were kept intact. While membranes were ruptured, there was an increase in the frequency and amplitude of early decelerations thorughout labour. The significance and practical implications of the results are discussed.

Uterine activity in induced labour.

A study was made of the characteristics of oxytocin-induced labour. Twelve patients with, and eight without membrane rupture were closely matched for factors likely to influence the character and duration of labour. In both groups uterine activity increased until a stable state was achieved loowing which there was little alteration until delviery. The duration of labour was shorten in the group with ruptured membranes as compared with intact membranes although, paradoxically, the uterineactivity tended to be greater when the membranes were intact.

Fasting and cognitive function.

The effects of short-term fasting (skipping breakfast) on the problem-solving performance of 9 to 11 yr old children were studied under the controlled conditions of a metabolic ward. The behavioral test battery included an assessment of IQ, the Matching Familiar Figure Test and Hagen Central Incidental Test. Glucose and insulin levels were measured in blood. All assessments were made under fasting and non-fasting conditions. Skipping breakfast was found to have adverse effects on the children's late morning problem-solving performance. These findings support observations that the timing and nutrient composition of meals have acute and demonstrable effects on behavior.
