Effectiveness of Postoperative Analgesia in the Management of Acute Pain in Day-Case Surgeries

BACKGROUND: Surgery is the most common source of acute pain. AIM: To determine the intensity of acute pain following day case surgery and evaluate the effectiveness of the prescribed analgesics. METHODS: A descriptive observational study carried out at the main operating and the Urology Outpatient theatre suites of the University College Hospital, Ibadan. Seventy consecutive adult patients presenting for day case surgeries between July and September 2013 were recruited. The procedures were stratified as follows: peripheral, groin/perineal, urologic/endoscopy or orthopedic/plastic surgeries. The prescribed postoperative oral analgesics were paracetamol alone or in combination with diclofenac, tramadol or both. Postoperative pain intensity was assessed on arrival in the recovery room and at 6, 12, 24, 48, & 72 hours using the Verbal Intensity Pain Scale (VIPS). The pain scores were presented as mean±SD at different time intervals for each stratified surgical procedures and analgesics using tables and frequency bar charts. A mean pain score of less than 2 for each category of surgical procedures or analgesics group was considered as satisfactory pain control and thus effective analgesia. RESULT: The overall prevalence of moderate to worst possible pain after surgery in this study was 54.3% on arrival in the recovery room. The mean pain score was greater than 2 at 6 hours postoperative in all surgical categories except in patients who had peripheral surgeries irrespective of single or combination analgesic therapy. CONCLUSION: A high proportion of patients arrived in the recovery room with a high pain score; measures to improve intraoperative analgesia should be employed.
