BackgroundThere is an unmet need for a reliable method of airway management for patients in the lateral position. This prospective randomized controlled two-center study was designed to evaluate the feasibility of intubation using a flexible fiberoptic bronchoscope in the lateral position during surgery.MethodsSeventy-two patients scheduled for elective nonobstetric surgery in the lateral decubitus position requiring tracheal intubation under general anesthesia at Lishui Central Hospital of Zhejiang Province and Jiaxing First Hospital of Zhejiang Province from April 1, 2015, to September 30, 2015, were enrolled in this study. Patients were randomly assigned to the supine position group (Group S, n = 38) and the lateral position group (Group L, n = 34). Experienced anesthetists performed tracheal intubation with a fiberoptic bronchoscope after general anesthesia. The time required for intubation, intubation success rates, and hemodynamic changes was recorded. Between-group differences were assessed using the Student's t-test, Mann-Whitney U-test, or Chi-square test.ResultsThe median total time to tracheal intubation was significantly longer in Group S (140.0 [135.8, 150.0] s) compared to Group L (33.0 [24.0, 38.8] s) (P < 0.01). The first-attempt intubation success rate was significantly higher in Group L (97%) compared to Group S (16%). Hemodynamic changes immediately after intubation were more exaggerated in Group S compared to Group L (P = 0.02).ConclusionEndotracheal intubation with a flexible fiberoptic bronchoscope may be an effective and timesaving technique for patients in the lateral position.Trial RegistrationChinese Clinical Trial Register, ChiCTR-IIR-16007814; http://www.chictr.org.cn/showproj.aspx?proj=13183.
