Abstract
Background: The ultrasound-guided transversus abdominis plane (TAP) block has been demonstrated as a useful analgesia technique in lower-abdomen surgeries. We hypothesized that it could be the principal anesthesia technique for end-stage renal disease (ESRD) patients undergoing peritoneal dialysis (PD) catheter (PDC) implantation using the open dissection method. Methods: This was a single-center, prospective, randomized, and double-blinded study. All eligible patients were randomized into 2 groups: the TAP block group (n = 20) and the local anesthetic infiltration (LAI) group (n = 20). Results: Compared with the LAI group, the TAP block group revealed a remarkably lower visual analogue score, lower switching rate into general anesthesia, higher satisfaction rate, and less rescuing analgesic consumption during operation (p < 0.05). Both PD- and anesthesia-related complications were rare in the 4-week follow-up. Conclusions: The ultrasound-guided TAP block had better analgesic effect than LAI and can be used as a principal anesthesia technique for PDC implantation in ESRD patients without previous abdominal surgery.
