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.

Decontamination issues and perceived reliability of the laryngoscope--a clinician's perspective.
The laryngoscope is identified as a potential vector for cross-infection. Case reports are presented, as are reports of bacterial and occult blood contamination of laryngoscope blades and handles. ⋯ Repeated decontamination of laryngoscope blades has resulted in a perceived decrease in reliability. This is reflected in a departmental survey where 86% of respondents consider the standard laryngoscope is only intermittently reliable and that there is room for improvement.

A number of European studies have documented the ability of procalcitonin (PCT), a novel inflammatory marker, to discriminate patients with sepsis from those with other causes of systemic inflammatory response syndrome (SIRS). The aim of this study was to assess procalcitonin's performance in an Australian intensive care unit (ICU) setting to examine whether it could discriminate between these two conditions. One hundred and twenty-three consecutive adult ICU patients fulfilling criteria for SIRS were enlisted in the study. ⋯ Utilizing both tests resulted in a more sensitive screen than either one alone, while PCT was a more accurate diagnostic test for bacteraemia than CRP. The PCT value also differed between those who died in hospital and those who survived. Measurement of PCT alone or in combination with CRP can aid discrimination of septicaemia/bacteriemia with associated SIRS from non-infectious SIRS in an Australian ICU setting.

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.
