Summary

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.

Detailed description

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 %.

Conditions

• Obese

Interventions

Type	Name	Description
DEVICE	apnoeic	In group S, High-Flow Nasal Oxygen was performed after the patient lost spontaneous breathing until the end-expiratory oxygen concentration reached 95 %.
