Research Article Comparative study of preoperative and postoperative pulmonary function in open abdominal surgeries

To compare the post operative pulmonary function with the preoperative pulmonary functions in patients undergoing laparotomy. Methods: 50 patients undergoing laparotomy under general anaesthesia were tested for pulmonary functions (Forced vital capacity (FVC), Forced expiratory volume at first second (FEV1), Peak expiratory flow (PEF), Forced expiratory flow at 25% to 75% (FEF25%-75%) and blood gas analysis (pO2, pCO2) preoperatively and on the second postoperative day using RMS MEDSPIROR ® and capillary blood gas analysis. Results: There was a decrease in FVC, FEV1, PEF, FEF 25%-75%, pO2, pCO2 to 65%, 67%, 65%, 66%, 92% and 99% of the preoperative value respectively.
