Preoperative use of incentive spirometry does not affect postoperative lung function in bariatric surgery.
Morbidly obese patients undergoing general anesthesia for laparoscopic bariatric surgery are considered at increased risk of a postoperative decrease in lung function . The purpose of this study was to determine whether a systematic use of incentive spirometry ( IS ) prior to surgery could help patients to preserve their respiratory function better in the postoperative period . Forty-one morbidly obese ( body mass index [ BMI ] > 40 kg/m² ) c and i date s for laparoscopic bariatric surgery were consented in the study . All patients were taught how to use an incentive spirometer but then were r and omized blindly into 2 groups . The control group was instructed to use the incentive spirometer for 3 breaths , once per day . The treatment group was requested to use the incentive spirometer for 10 breaths , 5 times per day . Twenty experimental ( mean BMI of 48.9 ± 5.67 kg/m² ) and 21 control patients ( mean BMI of 48.3 ± 6.96 kg/m² ) were studied . The initial mean inspiratory capacity ( IC ) was 2155 ± 650.08 ( SD ) cc and 2171 ± 762.98 cc in the experimental and control groups , respectively . On the day of surgery , the mean IC was 2275 ± 777.56 cc versus 2254.76 ± 808.84 cc , respectively . On postoperative day 1 , both groups experienced a significant drop of their IC , with volumes of 1458 ± 613.87 cc ( t test P < 0.001 ) and 1557.89 ± 814.67 cc ( t test P < 0.010 ) , respectively . Our results suggest that preoperative use of the IS does not lead to significant improvements of inspiratory capacity and that it is a not a useful re source to prevent postoperative decrease in lung function
