Does laparotomy under general anaesthesia reduce pulmonary function in patients undergoing open abdominal surgery?
Does laparotomy under general anaesthesia reduce pulmonary function in patients undergoing open abdominal surgery?
Pulmonary function is drastically reduced on the second postoperative day following laparotomy under general anesthesia.
Marked postoperative pulmonary decline after laparotomy may warrant monitoring; leaves open need for targeted interventions in future trials.
Objectives: 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 [FEV 1 ], Peak expiratory flow [PEF], Forced expiratory flow at 25% to 75% [FEF 25%-75% ] and blood gas analysis (pO 2 , pCO 2 ) preoperatively and on the second postoperative day using RMS MEDSPIROR and capillary blood gas analysis. Results: There was a decrease in FVC, FEV 1 , PEF, FEF 25%-75% , pO 2 , pCO 2 to 65%, 67%, 65%, 66%, 92% and 99% of the preoperative value respectively. Conclusions: Pulmonary function is drastically reduced after laparotomy.
