ClinConnect Summary

This clinical trial is studying how to safely and effectively help patients with obesity during a procedure called intubation, which is when a tube is placed in the airway to help with breathing. Bariatric surgery patients often have difficulties with intubation due to factors like extra weight and limited neck movement. The researchers will compare two special devices, the CMAC D-Blade and the CMAC Video stylet, to see which one works better for patients who may have a challenging airway, as identified by a tool called the Simplified Airway Risk Index (SARI).

To be eligible for this trial, participants must be adults aged 18 or older, have a body mass index (BMI) of 35 or higher, and have a SARI score of 4 or more, indicating a higher risk for difficult intubation. Those who are scheduled for elective bariatric surgery and meet these criteria can potentially take part in the study. It’s important to note that people with certain conditions, like a history of airway surgery or emergency surgery needs, cannot participate. If enrolled, participants can expect careful monitoring and evaluation to determine which intubation device works best for their unique situation.
