Gastropathy Clinical Trial
Official title:
IMPACT OF ALVEOLAR RECOVERY MANEUVER ON PULMONARY FUNCTION AND RESPIRATORY MECHANISM IN PATIENTS SUBMITTED TO BARIATRIC SURGERY ASSESSED BY ELECTROMAT IMPEDANCE TOMOGRAPHY: A RANDOMIZED CLINICAL TRIAL
Worldwide there is a high prevalence of morbid obesity with a progressive increase in incidence in recent years, causing serious consequences for the health services. Approximately 12% of the world population is obese and Brazil is in 77º without world ranking of countries in cases of obesity. In this context, bariatric surgery appears as an effective method of treating refractory obesity. Support of high fractions of oxygen administered during anesthesia is produced, it accepts the use of Positive Positive Positive Pressure (PEEP) through the Alveolar Recruitment Maneuver (ARM), which has been used allowing small fractions inspired by oxygen, which reduces intra-and postoperative atelectasis and optimizes gas exchange during anesthesia. In order to better monitor ventilatory mechanics, Electrical Impedance Tomography (EIT) appears as a cheap imaging method when compared to a non-invasive magnetic resonance imaging (CT) or MRI, with no side effects and recent studies shown in its life as pneumothorax , MRA monitoring, collapse detection, and PEEP titration. The aim of this study is to evaluate the impact of ARM and its repercussions on lung function and respiratory mechanics. This is a randomized controlled clinical trial with patients undergoing videolaparoscopic gastroplasty surgery, of both sexes. Patients were randomly assigned to Control Group and Experimental Group. Patient evaluation is performed without before, during and postoperative, through a pulmonary function test and EIT.
