Prolonged per-laryngeal endotracheal intubation in children: 40 years on.

Because tracheostomy has a very high complication rate in small children, prolonged mechanical ventilation was not performed satisfactorily in infants until a technique was developed that allowed prolonged per-laryngeal endotracheal intubation in children. Plastic polyvinyl chloride endotracheal tubes were introduced in the 1950s; they soften at body temperature, and are much less likely to cause subglottic stenosis than endotracheal tubes made from metal or rubber. The first account of prolonged per-laryngeal intubation of infants using polyvinyl chloride tubes was written by Dr Bernard Brandstater, and this remarkable document is reproduced here. It sets out all the important principles of endotracheal intubation in children: the tube must fit easily through the cricoid ring, it must be firmly fixed in place with the tip in the mid trachea, meticulous humidification and suction are essential, and the tube should be changed only if there are signs of obstruction.
