A multicentre randomised controlled trial of the McGrath ™ Mac videolaryngoscope versus conventional laryngoscopy
Authors' conclusion
This study demonstrates that using McGrath videolaryngoscopy compared with direct laryngoscopy improves first-pass tracheal intubation success in patients having elective surgery.
