Table 2 Characteristics of the nine studies comparing videolaryngoscopy to direct laryngoscopy
1st author | Journal, year | Setting | Patients’ characteristics | Personnel performing ETI | Videolaryngoscope model | Primary outcome | Comments |
|---|---|---|---|---|---|---|---|
Yeatts DJ et al. [22] | J of Trauma and Acute Care Surg, 2013 | Trauma resuscitation unit | Adult critically ill trauma patients | Emergency medicine residents, anesthesiology residents, attending anesthesiologists, nurse anesthetist | GlideScope | Survival to hospital discharge | No difference in the subgroup with anticipated difficult airways. Higher incidence of severe desaturation and worse mortality in the subgroup of head-injured patients intubated with videolaryngoscope |
Griesdale DEG et al. [23] | Can J Anesth, 2012 | ICU, ordinary ward, ED | Adult critically ill patients | Medical students or non-anesthesiology residents | GlideScope | Number of intubation attempts | No difference in intubation attempts. Significantly better visualization in the videolaryngoscope group, but lowest SaO2 during first attempt |
Kim JW et al. [24] | Resuscitation, 2016 | ED | Adult patients in cardiac arrest | Experienced intubators | GlideScope | Success rate of ETI by the intubator | No difference in the incidence of esophageal intubation and tooth injury. Chest compression interruption during CPR were longer in the direct laryngoscopy group |
Goksu E et al. [25] | Turk J Emerg Med, 2016 | ED | Blunt trauma patients | Residents and attending physicians of the ED | C-MAC | Overall successful intubation | Better glottis visualization and decreased esophageal intubation rate with videolaringoscopy. No difference in success rate even separating easy and difficult intubations |
Janz DR et al. [26] | Crit Care Med, 2016 | ICU | Adult critically ill patients | Pulmonary and critical care fellows | McGrath Mac or GlideScope or Olympus | Intubation on first attempt, adjusted for the operator’s previous experience | Better glottis visualization with videolaryngoscopy. No other differences |
Driver BE et al. [27] | Acad EmergMed, 2016 | ED | Adult critically ill patients | Senior residents | C-MAC | First-pass success rate | No difference in duration of first attempt, aspiration, hospital length of stay. No difference in success rate in the subgroup with anticipated difficult airways |
Sulser S et al. [28] | Eur J Anaesth, 2016 | ED | Adult critically ill patients | Experienced anesthesia consultants | C-MAC | First attempt success rate | Better glottis visualization in the videolaryngoscopy group. No difference in desaturation episodes or complications |
Lascarrou JB et al [29] | JAMA, 2017 | ICU | Adult critically ill | ICU physicians | McGrath Mac | Successful first-pass intubation | Better glottis visualization, but higher number of life-threatening complications with videolariyngoscopy. No difference in success rate even stratified for operator experience and expected difficult airways. No difference in number of intubation |
Silverberg MJ et al. [30] | Crit Care Med, 2015 | ICU and ordinary wards | Adult critically ill patients | Pulmonary and critical care fellows | GlideScope | First-attempt success rate | Better glottis visualization and lower number of attempts in the videolaryngoscopy group. No difference in overall complications rate. Neuromuscular blocking agents were not used |
