Magnitude And Associated Factors Of Difficult Airway In Adult Patients Who Underwent Elective Maxillofacial Operation With Endotracheal Intubation At Selected Public Hospitals Addis Ababa Ethiopia 2021 Cross-sectional Study.

Background: Difficult airway is a phenomenon in which there is a problem in maintaining gas exchangernvia a mask, an artificial airway or both. Degree of difficulty is associated with patient‟s airway anatomyrnand health status, clinical settings, surgical procedures that are being performed and experience of thernpractitioner. It results morbidity and mortality specifically in developing countries where equipment thatrnaids for difficult airway management is not accessible. rnObjective: To assess magnitude and associated factors of difficult airway in adult patients whornunderwent elective maxillofacial operation with endotracheal intubation at selected public hospitals,rnAddis Ababa, Ethiopia, 2021: A cross-sectional study.rnMethods: A cross-sectional study was conducted from January 22/2021 to May 21/2021 on 208rnparticipants at three selected public hospitals in Addis Ababa that provide maxillofacial surgery.rnHospitals were selected purposively. A review of logbook showed that 216 patients underwent surgery inrnfour consecutive months before data collection process. Actual study participants who met inclusionrncriteria were (n = 208). Data were analyzed using SPSS version 24. Binary and multivariate logisticrnregression were used to measure association between the factors and outcomes at 95% CI using AOR. Prnvalue below 0.05 was considered as statistical significance. rnResults: A total of 208 participants were investigated. We found that magnitude of difficult airway, difficultrnlaryngoscopy, difficult intubation, difficult mask ventilation and failed intubation were 23.1%, 17.8%, 16.3%,rn5.3 and 0.96% respectively, but there were no cases with „Can‟t Ventilate Can‟t Intubate‟ situation. Upper lip rnbite test class III, oropharyngeal view class IV, sternomental distance below 12cm, thyromental distancernbelow 6cm, body mass index above 30kg rn rn, age above 55 years and history of snoring were anrnindependent predisposing factors for difficult airway. rnConclusion and Recommendations: The extent of the problem was considerably high; thus, wernrecommend anesthesia providers and hospital administrators to give emphasis. Availability of fullyrnequipped facilities, appropriate use of alternative techniques and laryngeal manipulation are highlyrnrecommended to decrease the incidence.
