Intraop Ventilation Management & Postop Pulmonary Complications in High

Status Active, not recruiting

Clinical Trial Summary

Lung protective ventilation (LPV) has been proposed to reduce the incidence of postoperative pulmonary complications (PPCs), and protect against ventilator induced lung injury (VILI).

Clinical Trial Description

LPV was first introduced in the intensive care units but has been recently adopted in the operating rooms. Obstructive sleep apnea (OSA) is a widely prevalent condition in obese patients and requires special attention in the operating room. Screening for OSA risk in surgical patients is a common practice. The STOP-BANG questionnaire is a common screening tool for OSA (Snoring, Tiredness, Observed apnea, high blood Pressure, BMI, Age, Neck circumference, and male Gender). The American Society of Anesthesiologists practice guidelines for the perioperative management of patients with OSA do not recommend any specific ventilation strategy to prevent PPCs in this population. To the knowledge of the investigators, the association between intraoperative ventilation strategies and PPCs in laparoscopic bariatric surgery patients, who have a high STOP-BANG score, has not been adequately investigated. The investigators propose a retrospective chart review of patients, 18 years of age and older, who underwent laparoscopic bariatric surgery, in reverse Trendelenburg position, using pressure controlled ventilation (PCV/PCV-VG) at the Ohio State University Wexner Medical Center, between January 01, 2012 and November 22, 2016, to determine whether intraoperative driving pressure is a predictor of postoperative pulmonary complications. No procedures will be done for the sake of conducting this study except for a retrospective review of patient charts. Preoperative and intraoperative variables will be collected to determine their predictive value of postoperative complications. No risks to the patients' health or well being are anticipated due to the conduct of the proposed study. No immediate benefits to the patients from whom data was collected is anticipated either. Results obtained from this study may provide valuable information on the preferred ventilation strategies in the operating room for future patients who have a high risk of postoperative lung complications. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

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.
