Impact of Acetazolamide in Reducing Referred Postoperative Pain

• Status: Recruiting

• Participant gender: Male

Summary

Robotic assisted laparoscopic prostatectomy (RALP) is the standard treatment for prostate cancer, due to the benefits of decreased blood loss and length of stay.The procedure involves removing a man's prostate using a minimally invasive robotic approach under the guidance of a surgeon. In order to gain sufficient access, carbon dioxide (CO2) is used to fill the surgical space in a process termed insufflation. Carbon dioxide is a mainstay in laparoscopic procedures because it is cost-effective, noncombustible and readily excreted via the respiratory system in healthy patients.

Insufflation with CO2, however, has been linked to post-operative referred pain secondary to peritoneal acidosis.This acidosis is suspected to be due to the formation of carbonic acid from the CO2 insufflation.Peritoneal acidosis, and its associated post-operative referred pain, may not be adequately treated with the current standard pain control regimen.
