Clinical Trial Summary

The investigators plan to compare insufflation pressures during robotic assisted laparoscopic prostatectomy (RALP). Standard pressure is typically 15 mmHg, while in a previous study the investigators determined that 6 mmHg is possible routinely. Therefore, the investigators plan to compare the clinical outcomes of participants at a pneumoperitoneal pressure of 15 versus 6 mmHg.


Description:

The investigators to examine the impact of low pressure during robotic assisted laparoscopic prostatectomy (RALP) with the intention of identifying whether lower pressures might benefit participants. The investigators hypothesize that a low insufflation pressure may provide an improvement in postoperative pain and abdominal distension in addition to potential physiologic benefits, and that these factors might then allow a shorter hospital stay. The investigators previously initiated a protocol in September of 2016 (IRB# 1066864) to perform RALPs at an insufflation pressure of 6 mmHg with the intention of increasing the pressure as needed on an individual participant level. In order to determine whether this might allow earlier discharge when successful, the investigators began allowing for same-day discharge in participants meeting appropriate criteria. Having now demonstrated feasibility in over 300 consecutive participants using this ultralow pneumoperitoneum protocol, the investigators now plan to conduct a randomized trial to compare a pressure of 6 mmHg with participants having RALP at a standard pressure of 15 mmHg to determine whether there is a true benefit.

Outcome

Type Measure Description Time frame Safety issue
Primary Postoperative Pain Medication Use The cumulative dose (milligrams) of each opioid medication administered was calculated and converted to milligram morphine equivalents (MME) for each participant. Through 1 week postoperatively
Secondary Post Operative Pain Scores Each participant was asked to rate their pain on a 0-10 scale, with higher numbers representing worse pain. Patients rated their pain at the following time points: in the post-anesthesia care unit (PACU) upon waking from anesthesia, at hours 4, 12, 16, and 20 after transfer to the floor, and immediately prior to discharge. The pain scores for each patient were averaged. Through discharge (post-operative day 0 or post-operative day 1)
Secondary Operative Ventilation Average tidal volume (ml) Intraoperatively
Secondary Discharge Day (Post-operative Day 0 or 1) The day of discharge (post-operative day 0 or post-operative day 1) was recorded for each participant Through discharge (post-operative day 0 or 1)
