Abstract
Difficulties in mask ventilation have been associated with serious complicationsthat may result in death.Predictions may reduce the risks considerably. Our study aims were to assess the incidence and predictive values of anatomical parameters for difficult mask ventilation among patients who underwent elective surgeries.Cross sectional study was conducted on 278 patients. Patient demographics, incidence and predictive values of anatomical parameters fordifficult mask ventilation were studied.Our findings showed the incidence of difficult mask ventilation (grade III) as 2.2 %andimpossible mask ventilation (grade IV) as 0.4%. Highest percent of difficult mask ventilation (grade III) was occurred in patients with obstructive sleep apnea, BMI ˃26kg/m2, Mandibular Protrusion Class B andC, Neck cercumfrence˃40cm, history of snoring, and Modified Mallampatti Class III.All together, we conclude that Modified Mallampatti class III andMandibular protrusion class B & C are highly accurate parameters with high specificity, negative predictive value and positive predictive value for difficult mask ventilation (grade III) compared with other parameters.
