Abstract
BACKGROUND: The ultrasound-guided transversus abdominis plane (TAP) block is generally used for analgesia but not for anesthesia. A TAP block has a partial analgesic effect on the parietal peritoneum in abdominal surgeries. We hypothesized that an ultrasound-guided oblique subcostal TAP block, used as the principal anesthesia technique, could provide a better anesthetic effect on peritoneum stimulation in peritoneal dialysis catheter (PDC) implantation in end-stage renal diseases (ESRD) patients than local anesthetic infiltration (LAI). METHODS:End-stage renal disease patients undergoing PDC implantation were randomized into 3 groups: LAI Group, unilateral TAP group (Uni-TAP Group) and bilateral TAP group (Bi-TAP Group). A 40-mL dose of 0.25% ropivacaine was used for the regional block (LAI or TAP). The quality of anesthesia, visual analogue scale (VAS) of pain, cumulative rescuing sufentanil consumption, and venous plasma ropivacaine concentrations were compared among the 3 groups. RESULTS:Sixty-nine patients were enrolled, and higher 'Satisfied' anesthesia rates from nephrologists and patients were recorded in the 2 TAP groups, compared with the LAI Group. Significantly lower VAS scores were observed in the Uni-TAP Group at a majority of time points compared with the LAI Group. Less cumulative rescuing sufentanil was used in the 2 TAP groups (2.5 ± 2.7 and 3.0 ± 2.8 μg, respectively) compared with the LAI Group (5.8 ± 2.6 μg, p < 0.05). The median peak venous plasma ropivacaine concentrations were below the reported toxic threshold in all 3 groups. CONCLUSIONS: As the principal anesthesia technique, an ultrasound-guided unilateral oblique subcostal TAP block with 40 mL of 0.25% ropivacaine provided better anesthetic effect in PDC implantations in ESRD patients than LAI.
