The application of the jaw support and oropharyngeal airway ventilation in obese patients during the general anesthetic recovery

Objective:To compare the effects of the airway management between the jaw support ventilation and oropharyngeal airway ventilation in obese patients during the general anesthetic recovery.Methods:Forty obese patients scheduled by general anesthesia were randomly divided into the jaw support ventilation group(group A) and oropharyngeal airway ventilation group(group B)(20 cases each group).The group A and B were treated with the jaw support ventilation and oral pharyngeal airway ventilation after tracheal extubation,respectively.Two groups were treated with mask oxygen inhalation(oxygen flow min/2L) until awaking,and the further measures were taken when the pulse oxygen saturation(SpO2) was less than 90%.The changes of SpO2,respiratory rate(RR),mean arterial pressure(MAP),heart rate(HR) were observed,and the occurrence of restlessness,nausea,vomiting and laryngospasm were recorded at the beginning of entering the postoperative recovery room(T1),after 5 min(T2),10 min(T3),20 min(T4) of different modes of ventilation.Results:The levels of RR,MAP,HR and SpO2 were remained in the normal range.The differences of the SpO2 at each time-points between two groups were not statistically significant(P>0.05).The HR in group A was significantly less than that in group B at T2 and T3(P2,T3 and T4(PPP>0.05).Conclusions:The application effects between the jaw support ventilation and oropharyngeal airway ventilation in obese patients during the general anesthetic recovery are same.The effects of the jaw support ventilation on the vital signs and its complication of patients are less.
