Objectives The primary objective is to demonstrate that in patients undergoing major urologic
surgery, Patient Controlled Analgesia (PCA) opioid consumption in the first 24 hours after
surgery will be significantly less in patients who have had a single shot rectus sheath block
pre-operatively in addition to a post-operative rectus sheath continuous block via surgically
placed catheter versus those who only have post-operative rectus sheath continuous block.
Secondary outcomes will be opioid requirement intra-operatively, Numerical Rating Scale (NRS)
pain scores including maximum pain score in Post Anesthesia Care Unit (PACU) and score at 24
and 48 hours, incidence and severity of nausea, number of vomiting episodes, sedation score,
time to first bowel movement, time to first mobilization and duration of hospital stay.
