Summary

This completed study looked at 135 obese patients to see how different laryngoscopes (video vs. conventional) affect intubation difficulty and heart rate changes. The goal was to find which tool provides better airway visualization and fewer early complications like sore throat or nausea. The results could help guide safer airway management in obese patients.
