Comparison of time for endotracheal intubation with flexible tip bougie versus standard bougie during videolaryngoscopy in simulated cervical spine immobilization in adult patients – A randomized control trial
Authors' conclusion
FTB and SB guided total intubation time and number of intubation attempts with CMAC videolaryngoscope by the experienced anesthesiologists were comparable in simulated cervical spine stabilization. However, FTB insertion was significantly easier and shorter than SB insertion.
