The Effect of Mask Combined With High Flow Oxygen on Preoxygenation During Induction of General Anesthesia in Obese Patients
A study testing apnoeic in people with Obese, run by Henan Provincial People's Hospital at 1 site in China.
Trial 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. Read more about this study

About this study
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.
Read the 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 %.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
apnoeicDevice
In group S, High-Flow Nasal Oxygen was performed after the patient lost spontaneous breathing until the end-expiratory oxygen concentration reached 95 %.
| Study group | Role | What they receive |
|---|---|---|
| Smoking group | Experimental | In the Smoking group, the HFNC was performed after the patient lost spontaneous breathing until the end-tidal oxygen concentration reached 95 %. record the patient 's safe apnea time. Receives: Device: apnoeic |
| never smoking | No intervention | no intervention |
What is being measured
The primary outcome is the main question the study is designed to answer.
the safe apnoea times
Investigators will record the time of oxygen saturation drop to 95 % during intubation.
Measured: 5-minute
Secondary outcomes (1)
the Pao2 levels
the Pao2 levels after 5-minute pre oxygenation with high flow nasal oxygen in two groups of patients.
Measured: 5-minute

What does the primary outcome measure?
the safe apnoea times (time frame: 5-minute). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
