Abstract:
Objective To explore the effects of two kinds preoperative fasting and liquid-fasting time before caesarean section on blood glucose of puerperae with GDM before and after the operation,intra-operative complications and on blood glucose of neonates.Methods With prospective study method,162 puerperae with GDM admitted to obstetrical department of Peking University First Hospital and received cesarean section under combined spinal-epidural anesthesia between April 1st and Sep. 30th in 2015,were selected as the research object,and were divided into the control group (admitted on odd-numbered days) and the observation group (admitted on even-numbered days). Puerperae in the control group were forbidden to eat solid food for 8 h and drink transparent liquid for 6 h before the operation,while those in the observation group were forbidden to eat solid food for 6 h and drink transparent liquid for 2 h before the operation. Puererae in two groups were compared about their preoperative blood glucose,incidence of intraoperative nausea and vomiting or aspiration,intra-operative quality of bleeding,postoperative exsufflation time and blood glucose half an hour after the operation, meanwhile,neonates in two groups were compared about their Apgar scores 1 min and 5 min after birth,and their blood glucose half an hour after birth. Statistical analysis was done by independent-samplest test,Mann-WhitneyU test and χ2 test.Results Difference of preoperative blood glucose of puererae in two groups was statistically significant (P<0.01). Differences of intraoperative bleeding of puererae in two groups and blood glucose of neonates half an hour after birth in two groups were statistically significant (P<0.05). There was no statistic difference in the incidence of intraoperative nausea and vomiting or aspiration,postoperative exsufflation time of puererae,or Apgar scores 1 min and 5 min after birth of neonates in two groups(P>0.05).Conclusions The scheme of forbidding puererae from eating solid food for 6 h and drinking transparent liquid for 2 h before cesarean section can reduce the incidence of preoperative hypoglycemia,maintain a smooth post-operative blood glucose, reduce intraoperative bleeding without increasing the incidence of intraoperative complications like nausea,vomiting or aspiration,or hypoglycemia of the neonates. The new fasting and liquid-fasting scheme is safe and feasible,which makes it worth promoting in clinic.
