Effectiveness of Two Different Body Positions During Facemask Ventilation in Obese Patients

Effectiveness of Two Different Body Positions During Facemask Ventilation in Class 3 Obesity Patients: a Randomized Crossover Trial

Sponsor

Mount Sinai Hospital, Canada

Enrollment

50 participants

Start Date

Mar 25, 2024

Study Type

INTERVENTIONAL

Conditions

Obesity

Summary

It is important to provide enough oxygen to the patients who are asleep during surgery. One way to do this is by using a mask placed over the face to help them breathe. When it becomes difficult getting enough oxygen into the patient's body using the mask, it's called difficult mask ventilation. There can be different reasons for this, and having a higher BMI is one of them. Body physique is assessed by Body Mass Index (BMI). This calculation gives an indication of a person's weight relative to their height. There is some evidence in the research literature to suggest that when the patient is positioned in a way that helps their airway, like using a device to lift their head and torso 25 degrees , it might help the process of getting enough oxygen work better. The study aims to determine if patients with high BMI can breathe better using a face mask while they are in a head elevated position compared to lying flat on their back.

Interventions

OTHERHead position for face mask ventilation during induction supine

Participant to be ventilated starting 2 minutes after induction of general anesthesia via a face mask while in supine position. Participants will be crossed over to the head elevated position after the first measurement is obtained.
