Case ReportsARDS with severe hypoxia--aeromedical transportation during prone ventilation.
Severe hypoxia, despite maximal conventional respiratory support, is one of the few remaining limitations to aeromedical transportation. A case of a 35-year-old female, who was referred 36 hours following major trauma for transfer by air to a tertiary center, is presented. At the time of referral the PaO2/FiO2 ratio was 48. ⋯ The patient was turned and subsequently transported prone with resultant improvement in PaO2/FiO2 ratio to 260. There were no patient- or transport-related adverse events. The implication of prone positioning during aeromedical transportation is discussed.

Biography Historical Article Classical ArticleProlonged 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.

Severe cardiac failure associated with presumed jellyfish sting. Irukandji syndrome?
We present a retrospective review of twelve cases of Irukandji syndrome associated with pulmonary oedema. This is a life-threatening envenoming due to a presumed jellyfish sting throughout Northern Australia, although only one case occurred outside North Queensland. Patients presented with significant and ongoing pain, tachycardia and hypertension. ⋯ There was no death reported due to pulmonary oedema, but one patient died of intracerebral haemorrhage. We believe patients may develop a toxin associated cardiomyopathy, and jellyfish other than Carukia barnesi may be responsible. As there is confusion with nomenclature, Carukia barnesi should be known as the Barnes jellyfish, and the diagnosis of cardiotoxic marine envenoming is suggested for any patient who has been stung by a jellyfish, develops no or minimal skin markings, and develops cardiogenic pulmonary oedema associated with Irukandji syndrome.
