An interventional study of apnoeic in Obese, sponsored by Henan Provincial People's Hospital. Recruiting at 1 site in China. Open to male participants aged 18 Years to 80 Years, including healthy volunteers. Per ClinicalTrials.gov, last updated 2024-09-20.

There is a risk of airway-related incidents during anaesthesia associated with obesity. High-flow nasal oxygen is advocated for perioperative preoxygenation in obese patients to reduce airway adverse reactions. However, there have been no reports on whether smoking behaviors have an impact on obese men's Apnoeic oxygenation with high-flow nasal.This study compared the effects of smoking on the duration of safe apnoea times in obese males.
All patients were were divided into two groups based on smoking status: smokers(S groups), and never smokers(NS groups). Those in the smoking group were current smokers, while those in the nonsmoking group had never smoked. Both groups of patients were induced with intravenous anesthesia and received 5 minutes of high flow nasal oxygen (60 L min) prior to induction.After induction of anaesthesia, the patients were apnoeic until peripheral oxygen saturation decreased to 95 %.
6,297 studies on the registry are indexed under Obesity; 1,693 are open to participants now.
This study's planned enrollment of 60 is below the median of 78 across 4,879 interventional studies indexed under Obesity.
