Gastropathy clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Gastroplasty and Electrical Impedance Tomography

Start date: March 23, 2018
Phase: N/A
Study type: Interventional

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.
