Digital tracheal intubation and finger palpation to confirm endotracheal tube tip position in neonates: A systematic review and meta-analysis.

Abstract

BackgroundTo evaluate digital tracheal intubation (DTI) when compared to laryngoscope‐assisted TI; finger palpation of endotracheal tube (ETT) tip position when compared to any standard method.DesignA systematic review of Medline, Embase, CENTRAL, and CINAHL with synthesis of data using meta‐analysis was performed.Main outcome measureThe proportion of successful TI and correct ETT tip positioning were the main outcome measures.ResultsFive studies (one observational study and four RCTs) enrolling 310 neonates were included. 94% (81%–98%) of the DTI were successful on the first attempt (certainty of evidence [CoE]: low). The proportion of successful intubation on the first attempt was higher with DTI when compared to laryngoscope‐assisted TI (RR 95% CI: 1.81 [1.18; 2.76]) (CoE: very low). Time to successful TI with DTI was 7.4 (95% CI: 6.3, 8.5) s (CoE: low). Time to successful TI was significantly shorter with DTI when compared to laryngoscope assisted TI (MD [95% CI]: −4.9 [−7.3, −2.4] s) (CoE: very low). There was a trend towards a higher proportion of correct ETT tip positions with finger palpation when compared to weight‐based formulae alone (RR 95% CI: 1.12 [0.96; 1.31]) (CoE: very low).ConclusionsDTI and finger palpation to ascertain ETT tip position in neonates are promising strategies. Future studies with emphasis on their learning trajectory and generalizability are needed.
