Peri-operative multimodal pain therapy for caesarean section: analgesia and fitness for discharge.
OBJECTIVE
To compare, the efficacy of a multi-modal analgesic regimen and single drug therapy with iv PCA morphine alter Caesarean delivery with spinal anaesthesia.


METHODS
Forty ASA 1-2 parturients presenting for elective Caesarean section were randomized to receive multimodal pain treatment with intrathecal morphine, incisional bupivacaine and ibuprofen+acetaminophen po until hospital discharge (Group 1) or conventional therapy with iv PCA morphine weaned to acetaminophen+codeine po (Group 2). Both groups received spinal anaesthesia with 1.7 ml hyperbaric bupivacaine 0.75%. Visual analog pain scores at rest (RVAPS) and with movement (DVAPS) were recorded q 2 hr during the first 24 hr, then q 4 hr until discharge. Time to first walking, eating solid food, flatus, bowel movement, voiding and hospital discharge were recorded.


RESULTS
Pain scores were lower in Group 1 patients during the first 24 hr after spinal injection RVAPS 0.6 +/- 0.1 in Group 1 vs 2.1 +/- 0.1 in Group 2 (mean +/- SEM), DVAPS 1.9 +/- 0.1 in Group 1 vs 4.1 +/- 0.1 in Group 2 (P < 0.0001). Times to first flatus, 36.1 hr +/- 2.9 vs 20.5 +/- 1.8 (P < 0.05) and to first bowel movement, 74.8 hr +/- 5.6 vs 57.4 +/- 4.7 (P < 0.0001) were longer in Group 2 patients. There was no difference between groups in time to eating solid food, walking or hospital discharge.


CONCLUSIONS
Multi-modal pain therapy resulted in improved early post-operative analgesia during the first 24 hr after Caesarean delivery. Patients receiving iv PCA morphine followed by acetaminophen+codeine po were more likely to develop decreased bowel mobility. All patients, with one exception, achieved discharge criteria (eating solid food, absence of nausea, normal lochia, dry incision and DVAPS < 4) at 48 hr after spinal injection.
