Abstract:

Objective　 To evaluate application of videolaryngoscopy in patients with an abnormal anatomy in airway who suffer cerebral aneurysm embolization.　Methods　30 patients suffered emergency cerebral aneurysm embolization, ASA II or III, and with Mallampati airway (grade III～IV), were randomly divided into two groups: UE videolaryngoscopy (group A, n=15) and Macintosh direct laryngoscopy (group B, n=15). Tracheal intubation time, success rate of intubation, SpO2, HR, SBP and DBP: before tracheal intubation(T0)，tracheal intubation(T1)，1（T2）、3（T3）and 5（T4） minutes after tracheal intubation were investigated. The adverse reactions were also recorded during tracheal intubation.　Results　HR、SBP、DBP and PaCO2 in group B were higher at T1, T2,T3 than group A (P<0.05). HR,SBP and DBP in group B were higher at T4 than group A (P>0.05). Tracheal intubation time in group B was longer than group A. The ratio of adverse reactions in group A was lower than group B.　Conclusion　UE videolaryngoscopy can reduce stress reactions of tracheal intubation in patients with an abnormal anatomy in  airway who suffer cerebral aneurysm embolization, and effectively protect the safety of patients around anesthetic time.
