ASSESSMENT OF STANDARD ANTHROPOMETRIC AIRWAY CHARACTERISTICS RELEVANT FOR AIRWAY MANAGEMENT OF PATIENTS WITH OBSTRUCTIVE SLEEP APNEA SYNDROME DURING SLEEP BREATHING DISORDER SURGERY: A RETROSPECTIVE, SINGLE CENTER STUDY.
The aim of this study was to explore standard anthropometric airway characteristics of patients with obstructive sleep apnea syndrome (OSAS) and determine the incidence and risk factors for difficult airway management. Final analysis included 91 patients with polysomnography-verified diagnosis of OSAS who underwent sleep breathing disorder surgery under general anesthesia with direct laryngoscopy oroendotracheal intubation. The incidence of difficult manual mask ventilation during anesthesia induction, difficult intubation and immediate postextubation respiratory complications was 17.6%, 7.7% and 7.7%, respectively. ⋯ The OSAS patients with difficult intubation had more Cormack-Lehane score ≥3 (p=0.002) in comparison to those without difficult intubation. Our study demonstrated that manual mask ventilation during anesthesia induction was the most troublesome airway management task in OSAS patients during sleep breathing disorder surgery. Cormack-Lehane score was a relevant determinator of difficult mask ventilation and difficult intubation, while Mallampati score and BMI were relevant determinators only for difficult manual mask ventilation.
