Abstract: 【Abstract】〓Objective〓To observe the clinical effect of reinforced laryngeal mask airway on neurointerventional emergency operation. Methods〓Sixty patients scheduled for neural interventional treatment under general anesthesia were randomized into two groups: group T (tracheal intubation) and group L (reinforced laryngeal mask airway)..SBP,.HR, SPO2 and BIS in both group were recorded at different time points as following: immediately before and after anesthesia induction (T1 and T2),.1 min after endotracheal tube placement or laryngeal mask airway insertion (T3), femoral artery puncture (T4), the end of the operation (T5) and immediately after extubation (T6). Emergence time from anesthesia, consumption of propofol and remifentanil, the success rate of first insertion and total insertion were recorded or calculated. Also,.the occurrence of possible adverse effects such as bucking, regurgitation and aspiration,.laryngeal spasm and emergence agitation were recorded..Results Compared with group T, the value of SBP and HR of group L decreased significantly at T3, T6 (P<0.05). In group T, at the time points T3 and T6, the value of SBP was obviously higher and HR was significantly faster than that at T1 (P<0.01), while there was no such difference in group L. Compared with group T, the recovery time was significantly shorter (P<0.05), and the consumption of propofol and remifentanil,the incidence of postoperative bucking and emergence agitation were reduced obviously in group L, (P<0.05), while the value of SPO2 and BIS, the success rate of first insertion and total insertion, along with the incidence of regurgitation and aspiration, laryngeal spasm had no statistically difference between two groups. Conclusion〓The application of reinforced laryngeal mask airway in neurointerventional emergency treatment can not only maintain the stability of hemodynamics during intubation and extubation, but also shorten recovery time with less adverse effects.
