ObjectiveTo determine the incidence, indicators and clinical impact of difficult tracheal intubations in the neonatal intensive care unit (NICU).DesignRetrospective review of prospectively collected data on intubations performed in the NICU from the National Emergency Airway Registry for Neonates.SettingTen academic NICUs.PatientsNeonates intubated in the NICU at each of the sites between October 2014 and March 2017.Main Outcome MeasuresDifficult intubation was defined as one requiring three or more attempts by a non-resident provider. Patient (age, weight and bedside predictors of difficult intubation), practice (intubation method and medications used), provider (training level and profession) and outcome data (intubation attempts, adverse events and oxygen desaturations) were collected for each intubation.ResultsOut of 2009 tracheal intubations, 276 (14%) met the definition of difficult intubation. Difficult intubations were more common in neonates <32 weeks, <1500 g. The difficult intubation group had a 4.9 odds ratio (OR) for experiencing an adverse event and a 4.2 OR for severe oxygen desaturation. Bedside screening tests of difficult intubation lacked sensitivity (receiver operator curve 0.47-0.53).ConclusionsDifficult intubations are common in the NICU and are associated with adverse event and severe oxygen desaturation. Difficult intubations occur more commonly in small preterm infants. The occurrence of a difficult intubation in other neonates is hard to predict due to the lack of sensitivity of bedside screening tests.© Author(s) (or their employer(s)) 2019. No commercial re-use.
