Ultrasound-guided left lateral transversus abdominis plane block combined with rectus sheath block in peritoneal dialysis catheter placement

Abstract

This study assessed the utility of ultrasound-guided lateral transversus abdominis plane (TAP) block combined with rectus sheath (RS) block for peritoneal dialysis catheter placement surgery. Thirty consecutive patients with end-stage renal disease scheduled to have peritoneal dialysis catheter placement received a left lateral TAP block combined with RS block performed under ultrasound guidance. The TAP and RS blocks were, respectively, conducted with 15 ml of 0.5% ropivacaine and 10 ml of 0.5% ropivacaine. Pain intensity was evaluated by verbal rating scale during operation, and the degree of patient and surgeon satisfaction was qualified by a categorical scale. Twenty-nine patients received successful blocks without any other adjuvant anesthetic drugs. One patient required rescue analgesia with lidocaine infiltration. No complications related to regional anesthesia were noted. Ultrasound-guided left lateral TAP block combined with RS block can serve as the primary anesthetic modality for peritoneal dialysis catheter placement surgery.
