Videolaryngoscopy Versus Direct Laryngoscopy for Endotracheal Intubation of Obese Patients: a Prospective Randomized Trial

Videolaryngoscopy Versus Direct Laryngoscopy for Endotracheal Intubation of Obese Patients: a Prospective Randomized Trial

Patients were randomly assigned (1:1) to either a Macintosh laryngoscope group ("Macintosh group") or a videolaryngoscope group ("Video group").

In the Macintosh group, intubation was performed with a standard curved Macintosh blade. In the Video group, intubation was performed with the assigned videolaryngoscope. If intubation proved difficult with the initially assigned device, anaesthesiologists could switch to the alternative method at their discretion (rescue technique).

• Inclusion criteria: Adult patients (> 18 years) of both sexes with BMI > 35 kg/m² scheduled for laparoscopic sleeve gastrectomy (ASA < IV).

• Exclusion criteria:

• Patient's refusal to participate.
• Known allergy to drugs used during anaesthesia.
• Chronic pain syndromes.
• Chronic opioid use.
