Comparison of post operative pulmonary function between open surgeries and laparoscopies

Respiratory function is depressed after abdominal surgery. Less trauma to the abdominal wall results in early postoperative recovery. The study was planned to compare recovery of postoperative respiratory functions between open surgeries and laparoscopic surgeries in the Indian population. 50 patients undergoing open surgery and 50 patients undergoing laparoscopy underwent tests on pulmonary functions (Forced Vital Capacity [FVC], Forced Expiratory Volume in first second [FEV1], Forced Expiratory Flow between 25% and 75% [FEF25%-75%]), Peak Expiratory Flow [PEF]and capillary blood gas analysis (paO2, paCO2) before surgery and after two days following surgery using RMS MEDSPIROR® and blood gas analysis of capillary blood. Change in FVC, FEV1, FEF25%-75%, PEF, pO2 and pCO2 to 65.9%, 66.9%, 66%, 64.9%, 92% and 99% respectively of the preoperative value following open surgery and to 82.5%, 84%, 86%, 82.5%, 97.5% and 102% respectively of the preoperative value following laparoscopic surgery. Respiratory function recovery is better in laparoscopic surgery compared to open surgery.
