Effects of Nonsteroidal Anti-Inflammatory Drugs as Patient Controlled Analgesia on Early Bowel Function Recovery after Radical Cystectomy.

This study aimed to evaluate the effects of ketorolac, a commonly used non-steroidal anti-inflammatory drug (NSAID) as patient controlled intravenous infusion analgesia (PCIA) for the patients underwent radical cystectomy (RC) due to bladder cancer regarding post-operational indices of recovery. Total seventy patients who underwent radical cystectomy for the treatment of bladder cancer were included in the study. 35 patients received ketorolac as PCIA (NSAIDS group) and 35 patients had morphine infusion as PCIA (morphine group). Pain intensity, bowel function recovery and length of hospital stay were evaluated. Early postoperative complications were analyzed according to surgical types (robot RC vs. open RC). Demographics were similar between two groups. NSAIDS group showed a significant reduction in postoperative vomiting (p = 0.001), time to flatus (p = 0.028), time to first bowel movement (p = 0.001) and time to first clear liquid diet (p = 0.002) compared with morphine group. No statistically significant differences were observed between two groups regarding length of hospitalization, and postoperative complications. For 48 hours after RC, pain relief was slightly better in morphine group (p < 0.001). Both open RC and robot RC cases showed significantly better bowel function recovery with NSAIDS groups. Ketorolac as PCIA is relatively effective in pain management with better gastrointestinal recovery after RC.
