A comparison of the suction laryngoscope and the Macintosh laryngoscope in emergency medical technicians: a manikin model of severe airway haemorrhage

Emerg Med J. 2012 Jan;29(1):54-5. doi: 10.1136/emj.2010.101816. Epub 2011 Feb 18.


The use of a suction laryngoscope that enables simultaneous suction and laryngoscopy was evaluated. 34 emergency medical technicians intubated the trachea of a manikin with simulated upper airway haemorrhage using the suction laryngoscope and the Macintosh laryngoscope, in random order. When using the suction laryngoscope, the number of oesophageal intubations was lower (3/34 vs 11/34; p=0.021) and the time taken to intubation was shorter (mean (SD) 50 (15) vs 58 (27) s; p=0.041). In cases of airway haemorrhage, the use of the suction laryngoscope might be beneficial.
