Randomized Controlled Trial Clinical Trial
A randomized controlled trial to determine the effect of humidified carbon dioxide (CO2) insufflation on postoperative pain following thoracoscopic procedures.
It has previously been shown that the insufflation of humidified gas during laparoscopy results in less postoperative pain than is observed following the use of dry gas. Experimental evidence also suggests that dry gas insufflation during thoracoscopy results in greater structural injury to the pleura than occurs with the use of humidified gas. The present study was designed to determine the effect of humidified gas insufflation on postoperative pain following thoracoscopic procedures. ⋯ The use of humidified gas appears to reduce postoperative pain but not the rate of respiratory complications.
