ABSTRACT
Objective To investigate the effect of elevating the root of tongue bare-handed to assist ProSeal laryngeal mask airway insertion in patients with tongue body hypertrophy under general anesthesia. Methods Sixty ASAⅠ~Ⅲgrade patients with tongue body hypertrophy undergoing surgery in general anesthesia were randomly divided into two groups:30 cases in each group. After anesthesia induction ,laryngeal mask airway was inserted in the observation group with assistance of elevating the root of tongue bared-handed ,while inserted in the control group by standard method.Insertion time ,success rate of the first and secondary and total insertion ,pharyngolaryneal complications at 24 hours after removal were recorded ,as well as the success rate of gastric tube intubation was recorded. Results Compared with the control group ,insertion time was significantly shortened (P < 0.05). Success rate of the first and total insertion were increased (P < 0.05).Success rate of gastric tube intubation was increased(P < 0.05),and pharyngolaryneal complications were decreased (P < 0.05) in the observation group. Conclusions Elevating the root of tongue bare-handed to assist ProSeal laryngeal mask airway insertion in patients with tongue body hypertrophy is a simple and fast method with high success rate ,good apposition and less complications. Its efficacy is better than that of the standard method.
