THE EFFECT OF USING PACKED GAUZE IN THE EACH BUCCAL CAVITY OF EDENTULOUS PATIENTS ON FACILITY OF BAG MASK VENTILATION AFTER REMOVING DENTURES.

In the edentulous patients some authors suggest to leave dentures in when ventilating with bag-mask. In this research, we suggest a more efficient method.

Materials & Methods: In the prospective blind randomized clinical trial we included 200 patients (age≥55) into two groups. After induction of anesthesia in all groups, in the group I, we placed folded gauze in each buccal cavity, and then placed an oral airway. In group II, we placed only an oral airway after removing dentures. Then both of groups were ventilated with face mask and bag and successful bag-mask ventilation was assessed in each group. Success rates were recorded and compared using independent T-Test in SPSS 16.

Results: Successful bag-mask ventilation was achieved in 41 of 100 (41%) of group II compared with 91 of 100(91%) in group I. (odds ratio 0.06, 95% CI= 0.03–0.15, P= 0.0001).

Conclusion: Placing the packed gauze in buccal cavity after induction of anesthesia improves bag mask ventilation significantly.
