Determine the impact of a laparoscopic-guided transversus abdominis plane (TAP) block timing (at initiation or conclusion of procedure) on the postoperative pain experience in patients following robot assisted laparoscopic radical prostatectomy (RALP).
TAP block involves the use of a local anesthetic agent injected between the internal oblique and transversus abdominis muscles for the goal of pain relief. Often times these are performed under ultrasound guidance by the anesthesiology team preoperatively. The idea behind this is to provide a neurologic block to the sensory nerve fibers supplying the anterior abdominal wall, between the internal oblique and transversus abdominis muscles. More recently, this technique has been investigated in the setting of robot-assisted laparoscopic radical prostatectomy (RALP) with promising results. There i…

For treatment delivery, subjects will receive 60 mL of 0.25 percent ropivacaine with 4 mg of dexamethasone at the initiation of the procedure (immediately following placement of the robotic / laparoscopic camera port). The TAP block will be performed with 15 mL 2 finger breadths subcostal at the mid-clavicular line and then 15 mL at the level of the umbilicus along the mid-axillary line on each side. Laparoscopic / robotic camera will be used as a visual aid to confirm positioning between the internal oblique and transversus abdominis muscles for the goal of pain relief.
