PCA after subarachnoid block for cesarean section.

We studied the pain control, narcotic side effects, and PCA utilization with intravenous PCA morphine during 24 hours post cesarean section period. Fifty-two consecutive women were included in the study. Each received subarachnoid block with hyperbaric bupivacain with addition of fentanyl. After surgery, the patient received diclofenac suppository and IV-PCA commenced in the recovery room. Severity of pain and sedation was assessed hourly, and maximum pain and sedation scores for each 6-hour period were recorded. Two-third of the patients felt mild to moderate pain during transition from spinal analgesia to IV-PCA. Pain severity steadily improved during four 6-hour periods (p-value <0.001). Highest mean sedation score was noticed during the third six-hour postoperative period. Mean morphine consumption was 50 mg. The ratio between number of time PCA activated and dose received and pain score helped in managing the postoperative pain. Morphine IV-PCA, adequately replaces post cesarean section spinal (bupivacain-fentanyl) analgesia with fewer side effects.
