Analysis of the clinical effect for laryngeal mask ventilation combined with epidural anesthesla in anesthesia surgery

OBJECTIVE To evaluate the advantages for laryngeal mask ventilation combined with epidural anesthesia in anesthesia surgery.METHODS 80 patients with line of elective surgery from January 2009 to September 2011 were chosen.They were randomly divided into laryngeal mask anesthesia combined with epidural anesthesia group with 40 cases and tracheal intubation combined epidural anesthesia group with 40 cases.Continuously monitored on patients during surgery including blood pressure(BP),heart rate(HR),electrocardiogram(ECG),oxygen saturation(SPO2),end-tidal carbon dioxide partial pressure(PetCO2);recorded whether it was quiet when extubation or laryngeal mask was given,patients with or without cough,laryngospasm and vomiting,observed with or without throat ache.RESULTS After induction of anesthesia,MAP and HR in the two groups were significantly lower(P﹤0.05),after catheterization and giving laryngeal mask,MAP and HR were not different in laryngeal mask ventilation combined with epidural anesthesia group before and after the induction(P﹥0.05).MAP and HR increased rapidly(P﹤0.05)in endotracheal intubation combined with epidural anesthesia groupafter induction,there was a significant difference between the two groups(P﹤0.05).During the surgery:the values of MAP and HR were stable,recovered from anesthesia before induction,the difference between the two groups was not significant(P﹥0.05).Removing the catheter or the laryngeal mask:increase of MAP and HR was not obvious in laryngeal mask ventilation combined with epidural anesthesia group,and which were significantly higher than before induction in endotracheal intubation anesthesia combined with epidural anesthesia group(P﹤0.05),there was a significant difference between the two groups(P﹤0.05).The number of cases with quiet extubation in laryngeal mask ventilation combined with epidural anesthesia group was significantly more than in tracheal intubation combined with epidural anesthesia group,the former adverse reactions was significantly less than the latter.CONCLUSION The effect of laryngeal mask airway combined with epidural block anesthesia for surgery is effective,can maintain intraoperative ventilation and fewer complications,can be widely used in surgical anesthesia.
