Prevalence of Obstructive Sleep Apnea in Patients with Difficult Intubation: Looking for Evidence?

BACKGROUND: The link between obstructive sleep apnea and difficult intubation needs to be fully investigated made clear. If a compromised airway can anticipated managed; it lessen the likelihood of adverse consequences. AIM: aim this study was investigate incidence, severity, possible association in individuals with unexpected endotracheal their associated clinical polysomnographic findings. METHODS: Thirty patients referred for examination after were enrolled group, while 30 cases from laboratory unit database history surgical intervention without randomly selected control group. Documentation obtained office fiber-optic nasopharyngolaryngoscopy assessment by Muller maneuver. inspected upper graded clinically using Modified Mallampati technique. A comprehensive done overnight. available data anesthetic record, as well those derived examination, such age, sex, Body mass index, M score, positive findings, Cormack Lehane grade, Apnea-Hypopnea Index (AHI), desaturation average O2%, statistically analyzed. RESULTS: mean ± SD AHI group (29.7 16.1) (13.1 9.9), difference statistical significance (p < 0.001). grading severity (OSA) significantly different both groups, 53.3% studied having severe OSA rest moderate (26.7%) or mild (13.3%). index higher (28.9 17.4) than (10.2 7.4), O2% saturation lower among (91.8 6.2). modified score grade III-CL, also noticed class IV. CONCLUSION: is major risk factor management are more likely have intubations. Patients who underwent had incidence compared scores independently related.
