Minimally Invasive Surfactant Therapy Using a 2.0 mm Uncuffed Endotracheal Tube as the Conduit: An Easily Adaptable Technique

Minimally invasive surfactant therapy (MIST) is the accepted way of surfactant administration in Europe, and in 2018, we reported its successful outcome with three babies in Dubai. Although this procedure minimizes the barotrauma associated with intubation for surfactants, threading the fine infant-feeding tube is perceived to be technically difficult. Semi-rigid catheters like the angiocath and the less invasive surfactant administration (LISA) catheter simplify the procedure. We have used successfully the smallest size of endotracheal tube available (2.0 mm) as a surrogate LISA catheter in our neonatal unit in Dubai. We present herein the simplicity and ease of this procedure versus the conventional LISA or MIST technique.
