Background and Aims: Obesity is associated with restrictive ventilatory pattern which causes rapid oxygen desaturation. Although obesity is considered as a risk factor for difficult airway management, failure to achieve effective bag mask ventilation (BMV) can be catastrophic. This study tried to assess the effect of both propofol and sevoflurane on the efficacy of BMV during anesthetic induction in obese patients. Patients and Methods: A total of 200 cases were included, and they were randomly divided into two equal groups; Group S which included 100 cases who underwent sevoflurane induction, and Group P which included the remaining 100 cases who underwent propofol induction. Results: No statistically significant difference was detected between the two groups regarding patient and air way characteristics (P > 0.05). Difficult BMV (DBMV) was encountered in 19% and 37% of cases in Groups S and P, respectively. The incidence of DBMV was significantly increased in the P group (P = 0.005). Furthermore, the severity of difficulty was more marked in the P group. Logistic regression analysis revealed that thyromental distance, presence of macroglossia, presence of beard, lack of teeth, history of snoring, as well as propofol induction were risk factors for DBMV. Conclusion: Sevoflurane can facilitate BMV and provide better intubation conditions in comparison to propofol during anesthetic induction in morbidly obese patients. Moreover, decreased thyromental distance, presence of macroglossia and beard, lack of teeth, and history of snoring are considered preoperative indicators of DBMV.
