NCT05753046

Brief Summary

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).

Outcome Measures

Primary Outcomes (1)

  • Compare laparoscopic-guided TAP block timing (at initiation "early" or conclusion "late" of procedure) on the postoperative pain levels reported in patients following robot assisted laparoscopic radical prostatectomy (RALP).

    Comparison of patient reported pain scales, based on a score from 0 to 10. Where 0 is no pain and 10 is the worst pain.

    24 hours after RALP

Secondary Outcomes (7)

  • Compare the effects of TAP Block timing on total opioid consumption

    7 days after RALP with TAP Block

  • Compare the effects of TAP Block timing on hospital length of stay

    7 days after RALP with TAP Block

  • Compare the effects of TAP Block timing on return of bowel function

    7 days after RALP with TAP Block

  • Compare the effects of TAP Block timing on postoperative nausea/vomiting

    7 days after RALP with TAP Block

  • Compare the effects of TAP Block timing on ambulation

    7 days after RALP with TAP Block

  • +2 more secondary outcomes

Study Arms (2)

Early TAP Block

EXPERIMENTAL

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).

Drug: Early TAP Block

Late TAP Block

EXPERIMENTAL

For treatment delivery, subjects will receive 60 mL of 0.25 percent ropivacaine with 4 mg of dexamethasone either at the conclusion of the procedure (immediately preceding removal of the robotic / laparoscopic camera port).

Drug: Late TAP Block

Interventions

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.

Model Details: Patients who meet all eligibility criteria will be enrolled in the study and randomized (1:1) to receive either early or late TAP block. The subject and biostatistician will be blinded to the group allocation throughout the study. Research staff responsible for obtaining consent. To maintain the blind, initial analysis of the data performed by the biostatistician will not include group assignment.
