What this Trial Is About
Researchers are evaluating the effects of different inhalational anesthetics on lung function in obese patients undergoing bariatric surgery. The study focuses on comparing pulmonary function before anesthesia and after awakening, specifically examining the impact of sevoflurane versus desflurane during general anesthesia. It is known that pulmonary function often declines after anesthesia, and this study aims to clarify how these two anesthetics influence lung function in this patient group. Participants will be randomly assigned to receive general anesthesia with either sevoflurane or desflurane as the volatile agent during their bariatric surgery. The study monitors several anesthesia-related measures continuously during the procedure, including heart rate, oxygen saturation, carbon dioxide levels, and blood pressure. Lung function tests, such as forced vital capacity and peak expiratory flow, will be conducted three months before surgery and at 10 and 30 minutes after awakening from anesthesia. During the study, participants will undergo continuous monitoring of vital signs and anesthesia depth throughout surgery. Lung function assessments will be performed at set times before and after the procedure. Researchers will measure various lung function parameters to evaluate respiratory health changes related to the anesthetic used. The total participation includes preoperative assessments, surgery with monitored anesthesia, and short-term postoperative lung function tests to understand recovery dynamics.

Your Study Journey
Duration - 2 to 4 weeks
Participants are screened for eligibility to participate in the trial.
1 visit (in-person)
Duration - Duration of surgery and anesthesia
Participants undergo bariatric surgery under general anesthesia with either desflurane or sevoflurane. Pulmonary function and vital signs are monitored continuously during anesthesia.
1 surgery visit with continuous monitoring during anesthesia
Duration - 3 months before surgery through immediate post-anesthesia period
Pulmonary function tests are performed 3 months before surgery and repeated 10 and 30 minutes after emergence from anesthesia to assess recovery.
3 visits (1 before surgery, 2 shortly after surgery)
