Brief Summary

Reusable laryngoscope blades, which are the most commonly used devices for airway management, have been reported to be frequently contaminated and a possible source of infection. Although disposable laryngoscope blades are recommended to reduce the risk of infection, there are studies suggesting increased failed intubation attempt rates. The major cause of anesthesia-related mortality and morbidity is the failure of airway management. The incidence of difficult airway is reported to be 1-4% in normal population while it ranges up to 12-20% in obese patients. Following the introduction of disposable blades and considering the increased rate of failed intubation in obese patients with these devices, the investigators aimed to make a comparison of successful intubation rates of plastic and metallic disposable blades in morbidly obese patients

Conditions

Intubation;Difficult; Morbid Obesity

Keywords

Intubation; obesity; disposable blade

Outcome Measures

Primary Outcomes (1)

• comparison success rate of intubation in three different blades

  The investigators compared reusable metal, single-use metal and single-use plastic blades for their effectiveness in laryngoscopy and intubation in morbid obese patients.
