Objective: A prospective randomized trial was organized to compare the effectiveness of
general and regional anesthesia for cesarean section (CIS).
Method: Three hundred and forty-one patients were randomized into the general anesthesia
group (GA), epidural anesthesia group (EA) and spinal anesthesia group (SA). The effectiveness
of interest was success rate, blood loss and patient satisfaction.
Result: We found that the success rates of EA and SA were lower than GA. Success in EA
should be improved by using an epidural catheter to add more local anesthetic drug instead of a
single shot; and the surgeon should allow more time for the block to work adequately. Success
in SA should be improved by using bupivacaine instead of lidocaine. GA resulted in significantly
more blood loss, lower postoperative hematocrit, and higher proportion of patients who had postoperative
hematocrit
