Abstract：Objective To investigate the feasibility and safety of VivaSight double-lumen endobronchial tube(VDLT)intubation under visual laryngoscope in lateral position.Mehtods Sixty patients scheduled for elective thoracic surgery in Beijing Aerospace General Hospital from April 2021 to April 2022 were divided into two groups,lateral position intubation group(group L,n=30)and supine position intubation group(group S,n=30),according to random number table mehtod.Patients in group L were placed in lateral position all by themselves and then intubated under general ansthesia.Patients in group S were intubated first and placed in lateral position later.The number of medical workers involved in placing the lateral position and the time needed,Cormach-Lehane grade,intubation attempts and intubation time were recorded.Blood pressure and heart rate before anesthesia induction(T1),immediately before intubation(T2),on exposure of glottis(T3),1 min after intubation(T4),3 min after intubation(T5)and 5 min after intubation(T6)were also recorded.The incidence of VDLT displacement,sore throat and hoarseness of the patients after surgery were evaluated.Results Compared with group S,the number of medical workers involved was fewer,the time needed to place the lateral position was shorter,the incidence of VDLT displacement and postoperative complications related to intubation were less than those in group L(P<0.05).There were no significant difference in the Cormach-Lehane grade,intubation attempts,intubation time,blood pressure and heart rate at T1,T2,T3,T4,T5 and T6 between the two groups(P>0.05).Conclusion VDLT intubation under visual laryngoscope in lateral position is safe and feasible,which can be applied to patients undergoing thoracic surgery.
