Abstract

BACKGROUND
Epidural administration of morphine is a common method for postoperative analgesia in the lower abdominal surgery, but many complications can be produced. Since the pfannenstial incision lies within L1 dermatome, bilateral ilioinguinal and iliohypogastric nerve blocks(IINB) should provide analgesia after surgery through that incision.
METHODS
Forty patients undergoing cesarean delivery or total abdominal hysterectomy(TAH) through a pfannenstiel incision were randomly assigned to one of two groups: epidural morphine group(n=20) received 3 mg of morphine epidurally after surgery with epidural anesthesia; IINB group(n=20) performed IINB with 0.5% bupivacaine, 10 ml to each side after surgery with general anesthesia. Visual analogue scale(VAS) scores at resting and moving state, and complications were checked at 0, 2, 4, 8, 12, 24 hours after surgery.
RESULTS
Postoperative VAS scores did not show significant differences between the two groups at rest after 0, 2, 4, 8, 12, 24 hours and at moving state after 0, 2, 4 hours, but IINB group had less pain with movement than epidural morphine group at 8, 12, 24 hours after surgery(p<0.05). The incidence of pruritus was rare in IINB group(P<.05), but incidences of other complications were not significantly different between the two groups.
CONCLUSIONS
IINB is effective for analgesia after surgery through a pfannenstiel incision because of a lower incidence of complications and less postoperative pain with movement than epidural morphine, and can be performed to patients who have contraindications and difficulty for epidural analgesia.
