Evaluation of continuous wound infusion with local analgesics in postoperative renal transplantation patients: A retrospective study.

OBJECTIVES

The objective is to evaluate the efficacy of the continuous wound infusion (CWI) with Ropivacaine (naropeine 2 mg/ml) on postoperative pain, analgesics consumption, and bowel function in renal transplantation patients.

MATERIALS AND METHODS

A retrospective study trial including 79 patients who underwent renal transplantation. Patients were separated into two groups (catheter or without catheter). We identified 52 (65.8%) patients who received catheter wound infusion during the first 48 h postoperatively. On the other hand, 27 (34.1%) patients received standard without catheter anesthetic technique. Catheter wound infusion was achieved through a 12 cm catheter, inserted subcutaneously after abdominal closure. The catheter was placed above the external oblique aponeurosis. All postoperative data were examined to evaluate the first postoperative 48 h. This study aims to assess three variables: postoperative pain analysis through a visual analog scale, analgesics consumption, and bowel function.

RESULTS

The overall score of the three variables was studied. Regarding pain assessment, we have determined that the group of patients with catheter scored better than patients without catheter with borderline significance (66.3 vs. 61.2 consecutively; = 0.0843). An early bowel function was noted in patients with catheters on the 2 postoperative day ( = 0.0209). Moreover, patients without catheter consumed more painkillers with nonsignificant difference ( = 0.2499).

CONCLUSION

Patients with catheter showed earlier bowel function than the noncatheter group on the 2 postoperative day. The catheter group had better pain evaluation.
