COMPARISON OF FLOW AND VOLUME ORIENTED INCENTIVE SPIROMETRY ON LUNG FUNCTION AND DIAPHRAGM MOVEMENT AFTER LAPAROSCOPIC ABDOMINAL SURGERY: A RANDOMIZED CLINICAL PILOT TRIAL

Objective: This study was designed to evaluate the efficacy of two types of incentive spirometer (flow and volume) on pulmonary function and diaphragm excursion in patients who underwent laparoscopic surgery . Materials and Methods : Twenty sample sizes with eleven men and nine women who underwent laparoscopic surgery were randomly divided as follows: 10 subjects performed flow oriented incentive spirometer g roup, and other 10 subjects performed volume oriented incentive spirometer group. (Other therapies like br onchial hygiene therapy, Thoracic mobility exercise and mobilization performed both group) . All of them und erwent evaluations of pulmonary function test with measurement of forced vital capacity (FVC), forced expir atory volume in the first second (FEV1), FEV1/FVC ratio, peak expiratory flow (PEF) and diaphragm movement by ultra songraphy before the operation and first, second postoperative day(POD). Results: pulmonary function and diaphragm movement values between preoperative and postoperative (first, second) days were found to be higher in the volume oriented incentive spirometer group when compared to flow oriented incentive spirometer group. Conclusions: volume oriented incentive spirometry contributed towards early recovery of pulmonary function and diaphragm movement among patients who had undergone laparoscopic abdominal surgery
