Several studies worldwide have shown a higher Caesarean section rate in diabetic compared with non-diabetic women. Local audit conducted at our hospital revealed an emergency Caesarean section rate of 37.4% compared with 13.2% for non-diabetic women. We have investigated whether there is an intrinsic contractility problem in the myometria of pregnant diabetic women.
Methods: Myometrial biopsies were obtained during term elective Caesarean section from 20 diabetic and 68 non-diabetic women and were subjected to in-vitro laboratory testing. All the diabetic women had good antenatal glycaemic control. Contractility was measured simultaneously with intracellular calcium signalling using fluorescent Indo-1. Contractility was also measured in 0-glucose solutions and with the addition of 700 pM insulin. Myometrial glycogen content was measured in millimoles.
Results: The entire set of
