title: Comparison of spread of epidural anesthesia in pregnant and nonpregnant women.
abstract: Using a standardized epidural anesthetic technic, we compared levels of sensory anesthesia in patients undergoing cesarean section and in nonpregnant women undergoing elective surgery. When equal volumes of local anesthetic solutions were injected (either 15 ml or 20 ml of 0.75% bupivacaine without epinephrine), there was no statistically significant difference in sensory levels in pregnant and nonpregnant patients.
