Incidence of anesthesia related complications in multiple gestation patients undergoing cesarean delivery has not been reported in Thailand. The aim of this study is to identify complications that occur which may derived from different anesthetic techniques used, such as hypotension, uterine atony, postpartum hemorrhage, rate of hysterectomy, blood transfusion and fetal outcome.

Nowadays, the rate of multiple gestations is increasing considerably due to the prevalence of assisted reproductive technology. As physiologic changes from multiple gestations differ from singleton pregnancy, multiple gestations are considered a high risk pregnancy. A number of complications can occur from prenatal period such as preterm labor and increase rate of maternal beta agonist usage e.g. ritodrine, terbutaline and salbutamol. These drugs cause maternal tachycardia, hypokalemia and pulmonary edema. Multiple gestations increase rate of cesarean delivery and intraoperative complications such as postpartum hemorrhage and hysterectomy can be found 3.7 times and 2.3 times respectively higher than that of singleton pregnancy. Spinal anesthesia is the anesthetic technique of choice for parturients undergoing cesarean section, owing to its rapid onset of action, reliability, superior postoperative pain control and lower mortality rate than general anesthesia. However, the most important complication is maternal hypotension, especially in multiple gestations that may derive from more aortocaval compression comparing with singleton pregnancy. Nevertheless, some patients having contraindications for regional anesthesia e.g. thrombocytopenia, coagulopathy or pulmonary edema make anesthesiologists decide to put these patients under general anesthesia for cesarean section. General anesthesia for cesarean section in singleton pregnancy has been proved that can cause higher incidence of postpartum hemorrhage and higher rate of blood transfusion compared to regional anesthesia. Incidence of anesthesia related complications in multiple gestation patients undergoing cesarean delivery has not been reported in Thailand. The aim of this study is to identify complications that occur which may derived from different anesthetic techniques used, such as hypotension, uterine atony, postpartum hemorrhage, rate of hysterectomy, blood transfusion and fetal outcome.
