EVALUATION OF BREATHING MECHANICS DURING BARIATRIC PRE-SURGERY OF MODERATE AND MORBID OBESE

Abstract

The present study aims at an evaluation of breathing mechanics through muscular strength (Maximum Inspiratory Pressure - Max IP and Maximum Expiratory Pressure Max EP) and Forced Vital Capacity (FVC) in patients suffering from moderate and morbid obesity, before and after inspirometry of incentive during pre-surgery of bariatric surgery. Eleven patients were evaluated having diagnosed moderate and morbid obesity, associated or not with co-morbidity, from both sexes, with age ranging from 19 to 55, whom were to submit to bariatric surgery at Natal's Surgery Unit (UNICAD), from February 15 to May 23, 2005. A physiotherapeudic evalutation protocol was utilized as a data gathering instrument (Max IP, Max EP, FVC), control record and guidance in breathing exercises based on the UNICAD protocol. The study started upon the signing of free and conscious consent. For interference statistics a 't test' - Student was used, tuned in for  verifying the differences between the average values before and after the utilization of the breathing incentivator on the group to be analysed. As a result, we were able to obtain a marked improvement for IP Max pre motivator  99.09(± 37.27), post motivator 120.45(±43.50) with p=0.048, and FVC pre motivator 3.25(±0.93), post motivator 3.45(±1) with p=0.0009. Resulting from our data analysis we concluded that the practice of incentive inspirometry witheld before bariatric surgeries in obese patients promotes the growth of Max IP, Max EF and FVC values. We would suggest our study's continuity for better validating the benefits promoted by our evaluation and guidance through pre-surgery.
