‘Less invasive surfactant application’ requires insertion of a thin catheter into the trachea during laryngoscopy. Thin catheters cannot be used to give positive pressure ventilation, so their correct placement is determined by seeing them enter the trachea, rather than by other means (eg, detection of breath sounds, ‘misting’ in the tube or exhaled carbon dioxide). Videolaryngoscopy (VL) allows for confirmation of correct catheter insertion by multiple observers. Some thin catheters are pliable and require a Magill’s forceps for insertion,1 while other semirigid catheters do not.2 We rarely use Magill’s forceps at our hospital, so we studied five thin catheters that may be inserted without their use. Two …
