Intraoperative management of robotic-assisted versus open radical prostatectomy

Background and Objectives: Minimally invasive surgery has been shown to decrease postoperative morbidity and length of stay for several laparoscopic procedures. We sought to retrospectively compare intraoperative surgical and anesthetic parameters, postanesthetic care unit (PACU) length of stay, and hospital length of stay of patients who underwent roboticassisted laparoscopic radical prostatectomy (RAP) versus open radical retropubic prostatectomy (ORP). Methods: A retrospective investigation was performed using a urologic surgery database and an anesthesia electronic medical record. We queried information regarding 106 ORP patients from 2002 through 2007 and 575 RAP patients from 2007 through 2008. Results: Patients in the RAP group compared with ORP patients had reductions in surgical time, anesthesia time, estimated blood loss, crystalloid administration, and PACU and hospital length of stays. Compared with ORP procedures, intraoperative respiratory rates, peak inspiratory pressures, and arterial pressures in RAP procedures were higher; tidal volumes and heart rates were decreased; but end-tidal carbon dioxide concentrations were not different. In the RAP group, intraoperative complications included severe bradycardia, corneal abrasions, and 2 patients required reintubation. Surgically, no rectal perforations were noted, and no operative mortalities occurred. Conclusions: Our data demonstrate the safety and efficacy of RAP due to a combination of surgical and anesthetic factors.
