PurposeWe retrospectively analyzed the efficacy of abdominal peripheral nerve block (PNB) and caudal block (CB) in patients undergoing robot-assisted laparoscopic radical prostatectomy (RARP).MethodsPatients who underwent elective RARP at our hospital (Jan. 2015-Sept. 2016) were enrolled. We reviewed the 188 patients' anesthesia charts and medical records and divided the patients into three groups based on the anesthesia used in their cases: 76 patients in the total intravenous anesthesia (TIVA) group, 51 patients in the TIVA + abdominal PNB group (TI-PB group), and 61 patients in the TIVA + abdominal PNB + CB (TI-PB-CB group). We compared the groups' amounts of anesthetic drug usage, anesthesia times, and the presence/absence of additional opioid administration in the recovery room.ResultsThe perioperative opioid use during anesthesia was significantly greater in the TIVA group than in the TI-PB-CB group. The total amount of muscle relaxant was significantly higher (p < 0.001) in the TIVA group than the TI-PB-CB group: 60.0 (50.0-70.0) mg vs. 50.0 (40.0-60.0) mg. Although there were no significant differences in the operation time, the frequency of the use of additional opioid administration was significantly higher (p < 0.01) in the TIVA group than the TI-PB group: 23.7% vs. 2.0%, respectively.ConclusionsAlthough there was no influence on the anesthesia time, the muscle relaxant dose and the perioperative amount of opioid use were significantly less in the combined PNB + CB group. Our analyses suggest that not only PNB but also CB was useful for perioperative management in RARP.Clinical Trial Registration2016-1059.
