Ｏｂｊｅｃｔｉｖｅ　To observe the success rate of intubation of shaping double-lumen endotracheal tube（DLT） and postoperative hoarseness， sore throat， and to seek better DLT shaping provides the basis for intubation.　Methods　One hundred and sixty patients of ASAⅠ-Ⅲ with elective thoracic surgery under general anesthesia， randomly divided into the shape group and the no shape group to intubate DLT（n=80）. Each group according to each DLT is divided into two groups（group A， B， C， D， n=40）， and according to gender and each is divided into two subgroups（group A1， A2， B1， B2， C1， C2， D1， D2， n=20）. Two groups all use bright trachea intubation through the mouth， shape group adopts the "J" shape of DLT. The data related to intubation and positioning was recorded： intubation time， intubation attempts and the situation of reversing， the incidence and severity of postoperative hoarseness and sore throat were assessed.　Results　Two groups of patients with intubation time were（154±6） s and（185±13） s respectively（P＜0.05）， two groups of patients with intubation attempts were（1.4±0.4） times and（1.7±0.8） times respectively（P＜0.05）， and two groups of patients with the situation of reversing were 3 times and 11 times respectively（P＜0.05）. Comparison between the two groups for intubation time， intubation attempts and the situation of reversing， shape group were less than the no shape group， and has nothing to do with gender， but the left DLT than the right was easy to reverse. Two groups of patients with incidence of postoperative hoarseness is 15/80 and 33/80 respectively（P＜0.05）， two groups of patients with the incidence of postoperative sore throat were 15/80 and 31/80 respectively（P＜0.05）. Incidence of postoperative patients with hoarseness， sore throat， the shape group set lower than the no shape group overall（P＜0.05）， and was associated with gender.　Conclusions　“J” shape DLT intubation has the higher success rate and the smaller stimulation， can reduce the incidence of patients with postoperative hoarseness， sore throat， and has a certain clinical significance.
