Laborde Tracheal Dilator — Three-Bladed Spread

Laborde Tracheal Dilator — Three-Bladed Spread

Jean-Baptiste Laborde (1830-1903), Paris physician at the Hôpital Beaujon and the originator of the “Laborde maneuver” — rhythmic traction of the tongue with forceps to stimulate the gasping reflex in the apparently dead — designed his three-bladed tracheal dilator for the emergency tracheotomy that French physicians of his era often performed for diphtheritic croup obstruction. The three blades open in a tripod configuration, widening the tracheal opening for tube insertion without the lateral-wall pressure that a two-bladed dilator produces.

The diphtheria era

Diphtheria pseudomembrane formation in the larynx and upper trachea was a major cause of paediatric mortality in the pre-antitoxin era (before 1894); the emergency tracheotomy below the obstruction was the rescue intervention. The Laborde dilator was the standard tool for opening the trachea once the surgeon’s incision had been made. The procedure dropped diphtheria-related laryngeal mortality from over 70% to under 30% in the centres that adopted it routinely.

Modern survival

Modern emergency-tracheotomy is performed for trauma, severe burns, and the rare laryngeal obstruction not amenable to intubation. The Laborde three-bladed dilator remains in emergency-airway kits because its tripod geometry holds the airway open during stoma maturation and tube insertion better than the older Trousseau two-bladed design.
