McGrath Series 5 Videolaryngoscope for Double-lumen Tube Intubation

July 10, 2014 updated by: Wenlong Yao, Huazhong University of Science and Technology

Evaluation McGrath Series 5 Videolaryngoscope for Double-lumen Tube Intubation

  1. Double-lumen tube intubation is difficult, compared with single lume tube.
  2. McGrath Series 5 videolaryngoscope hase been used in difficult airway management, both in anesthetized and awake patients.
  3. But there was little information about McGrath Series 5 videolaryngoscope for double-lumen tube intubation.
