Comparison of tramadol versus tramadol with paracetamol for efficacy of postoperative pain management in lumbar discectomy: A randomised controlled study.

PURPOSE

Despite developments in the treatment of pain, the availability of new drugs or increased knowledge of pain management, postoperative pain control after different surgeries remains inadequate. We aimed to compare the postoperative analgesic efficacy of tramadol versus tramadol with paracetamol after lumbar discectomy.

DESIGN, SETTING, PARTICIPANTS: Sixty patients undergoing lumbar discectomy were randomly assigned into two groups.

METHODS

Patients in Group T (n = 30) received tramadol (1 mg/kg), and patients in Group TP (n = 30) received tramadol (1 mg/kg) with paracetamol (1 g) 30 minutes before the end of surgery and paracetamol was continued during the postoperative period at 6 hours intervals for the first 24 hours. Patient-controlled analgesia with tramadol was used during the postoperative period.

MAIN OUTCOME MEASURES

Duration, postoperative pain scores, Ramsay sedation scores, analgesic consumption, and side effects were recorded in all patients during the postoperative period. Continuous random variables were tested for normal distribution using the Kolmogorov-Smirnov test, than Student's t-test was used for means comparisons between groups. For discrete random variables chi-square tests and McNemar test was used.

RESULTS

Demographic data, mean duration of anaesthesia and surgery were similar in both groups. Postoperative pain scores were significantly higher in Group T than Group TP at 5; 15; 20; and 30 minutes (P = .021, P = .004, P = .002, P = .018). Late postoperative pain scores were similar. Total tramadol consumption in Group T (106.12 ± 4.84 mg) was higher than Group TP (81.20 ± 2.53) during the 24 hours postoperative period. However, continuing the paracetamol at 6 hours interval did not change late postoperative pain scores.

CONCLUSION

The administration of tramadol with paracetamol was more effective than tramadol alone for early acute postoperative pain therapy following lumbar discectomy. Therefore, while adding paracetamol in early pain management is recommended, continuing paracetamol for the late postoperative period is not advised.
