Objective To observe the effect on cardiovascular response and sore throat, hoarseness in the patients under lightwand-guided tracheal intubation. Methods 60 selective patients(ASAⅡ~Ⅲ) scheduled for cervical spine under general anesthesia were randomly divided into 3 groups, with 20 cases in each group. These were lightwand-guided(group A), ordinary laryngoscope(group B) and video laryngoscope(group C). HR and SBP were monitored and recorded at the time points of pre-induction(T0), immediately pre-intubation(T1), 1 min(T2), 3 min(T3), 5 min(T4). Cases of sore throat and hoarseness were also recorded at the point of 1 h, 12 h, 24 h postoperation. Results Values of HR and SBP in group A were significantly lower than those in group B and group C at T2(P0.05). Values of HR and SBP in group A were lower than that in group B at T3(P0.05). Cases of postoperative sore throat and hoarseness in group A were significantly lower than that in group B(P0.05). Conclusion Lightwandguided tracheal intubation can effectively suppress cardiovascular responses and reduce the incidence of postoperative sore throat and hoarseness, which can be widely used as a routine method of intubation with cervical spine trauma patients.
