SummaryWe compared the times to intubate the trachea using three techniques in 60 healthy patients with normal airways: (i) ®breoptic intubation with a 6.0-mm reinforced tracheal tube through a standard laryngeal mask airway (laryngeal mask)®breoptic group); (ii) ®breoptic intubation with a dedicated 7.0-mm silicone tracheal tube through the intubating laryngeal mask airway (intubating laryngeal mask)®breoptic group); (iii) blind intubation with the dedicated 7.0-mm silicone tracheal tube through the intubating laryngeal mask airway (intubating laryngeal mask)blind group). Mean (SD) total intubation times were signi®cantly shorter in the intubating laryngeal mask)blind group (49 (20) s) than in either of the other two groups (intubating laryngeal mask)®breoptic 74 (21) s; laryngeal mask)®breoptic group 75 (36) s; p < 0.001). However, intubation at the ®rst attempt was less successful with the intubating laryngeal mask)blind technique (15 ¤ 20 (75%)) than in the other two groups (intubating laryngeal mask)®breoptic 19 ¤ 20 (95%) and laryngeal mask)®breoptic 16 ¤ 20 (80%)) although these differences were not statistically signi®cant. We conclude that in this patient group, all three techniques yield acceptable results. If there is a choice of techniques available, the intubating laryngeal mask)blind technique would result in the shortest intubation time.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
