To compare the clnical data of general and regional anesthesia for cesarean section in patients with systemic hypertension.

We conducted a retrospective survey with the medical records of the patients with hypertensive disorders in pregnancy, who under went cesarean section from January 1998 to December 2012. We collected data including patients' demographics, anesthesia and maternal and neonatal outcome. According to anesthetic method, the subjects were divided into general anesthesia and regional anesthesia group and the clinical outcome were compared. We reclassified the patients according to the use of magnesium sul fate (MgSO₄) and compared the clinical outcomes.

Of the 1,050 hypertensive parturients, 848 (80.8%) patients went through cesarean section. Three hundred and sixty three patients (42.8%) underwent epidural anesthesia, general and spinal anesthesia were used in 268 (31.6%), and 217 (25.6%) patients, respectively. There was no significant difference in maternal and neonatal outcome according to anesthetic method. In the patients administered MgSO₄, 1 minute Apgar score was lower and maternal gestational age and birth weight were less than the patients not receiving MgSO₄.

Anesthetic methods did not have effect on outcome of cesarean section of the patients with hypertensive disorder of pregnancy.
