Transversus abdominis plane (TAP) block for laparoscopic live donor nephrectomy: Continuous catheter infusion provides no additional analgesic benefit over single-injection ropivacaine.

The lower pain score for placebo group at 60-hour postoperative is likely clinically insignificant. The TAP catheter infusion provided no benefit over a single-injection TAP block; thus, the added risk and cost are not supported. Liposomal bupivacaine should be evaluated in future studies.
