Randomized trial of low versus high carbon dioxide insufflation pressures in posterior retroperitoneoscopic adrenalectomy

In posterior retroperitoneoscopic adrenalectomy, greater insufflation pressures are associated with greater partial pressure of arterial CO2 and end-tidal CO2 and lesser pH at 60 minutes, be significant. Commencing with lesser CO2 insufflation pressures decreases intraoperative acidosis.
