【摘要】Objective:To assess the effects of lightwand and laryngoscopic intubation

techniques

in

patients

undergoing

laparoscopic

cholecystectomy (LC). Methods: 300 ASA physical status Ⅰ and Ⅱ patients, undergoing LC, were randomly assigned to two groups, with 150 cases in each group. Patients in the LS group underwent endotracheal

intubation

using

a

standard

direct-suspension

laryngoscopic technique. Patients in the LW group were intubated by using transillumination with a lightwand. Mean arterial pressure and heart rate were recorded before induction, and at 1, 3 and 5 min after intubation. The incidence and of sore throat, hoarseness, and dysphagia was assessed twenty-four hours after surgery. Results: This study demonstrated no clinically significant difference in cardiovascular variables between the two techniques. Patients had a significantly lower incidence of sore throat, hoarseness, and dysphagia when the lightwand was used for intubation. Conclusion: This study suggests that lightwand intubation may decrease the incidence of postoperative sore throat,
