Informed voluntary parturients planned for cesarean delivery will be informed about the study. The parturients will get prepacked glucose drink containing 100 g and 50 g glucose, respectively. They will consume the 100 g of glucose the night before the planned operation and the 50 g on the morning of the planned cesarean delivery. Their blood glucose level will be monitored by percutaneous continuous blood glucose monitoring every 30 minutes for 2 hours following the glucose dose in the evening and for four hours in the morning of the operation.~The subjective well being of these parturients will be also qualitatively assessed.
Diabetic parturients planned for cesarean delivery will be recruited for the study. They will receive a fixed glucose dose to mimize the effects of fasting preoperatively and their blood glucose levels will be monitored.
