Clinical implications of transversus abdominis plane block (TAP-block) for robot assisted laparoscopic radical prostatectomy: A single-institute analysis.

The aim of this study was to evaluate the role of TAP block in improvement of anesthesiological management and perioperative surgical outcomes of robot-assisted laparoscopic radical prostatectomy (RALP).

We consecutive enrolled 93 patients with prostate cancer whose underwent RALP at our department from January 2019 to December 2019. Group A included 45 patients who received bilateral TAP block, and Group B included 48 patients who did not received TAP block. TAP blocks were always performed by a single anesthesia team. An elastomeric pump device was used in all patients for post-operative pain management. TAP block was performed according to Rafi's technique, with Ropivacaine 0.375% and dexamethasone 4 mg. Mean values with standard deviations (±SD) were computed and reported for all items. Statistical significance was achieved if p-value was ⩽0.05 (two-sides).

The two groups showed no difference in the most important demographics and baseline characteristics (p > 0.05). Group A showed a significant longer time of anaesthesia. Moreover, Ketorolac doses (started dose plus continuous post-operative infusion via elastomeric pump) used in Group A were significantly lower than Group B. Despite this, Group B showed statistical significant higher value of NRS PACU and at 12, 24, 48, 72 h than Group A but not at 96 h. Rescue analgesic medication use was significantly higher in the Group B than Group A. Moreover, patency of the intestinal tract and time to ambulation was significantly lower in the Group A.

The use of TAP block during a RALP is a safe procedure that can be applied more appropriately to achieve better pain control. A multimodal protocol that includes locoregional anesthesia, reduction of intra and postoperative use of strong opiates, correct placing of the patient and the use of low pneumoperitoneum pressures should be implemented in order to reach a faster and better post-operative full recovery of patients whose underwent RALP.
