Multicenter StudyMetropolitan audit of appropriate referrals refused admission to intensive care.
We undertook a three-month prospective cohort study of critically ill adult patients referred to the Intensive Care Units (ICUs) of public hospitals in metropolitan Melbourne and Geelong, Victoria. The aim was to ascertain the prevalence and immediate consequences of "refused" admission amongst patients appropriately referred to the ICU of first choice. Between August 1 and October 31, 1999, 10 (out of 12) public hospitals collected data. ⋯ The reasons for "refusal" were limited staffing (52%) and shortage of beds (46%.) Acute inter-hospital transfer (1.7 per day) was the most common immediate triage outcome (57%). These rates are higher than previously reported figures. We conclude that refused admission to the ICU of first choice, and acute inter-hospital transfer in this region and time period, were common events.

Review Case ReportsSuccessful use of ECMO in adults with life-threatening infections.
Two cases of critically ill patients who received extracorporeal membrane oxygenation (ECMO) using different forms of circuitry and for different indications are presented. Both patients had life-threatening infections with septic shock and were not able to be supported by conventional means. ⋯ The second patient had psittacosis and received venovenous ECMO for respiratory failure. We discuss the expanding indications for this technology and the role it has to play in adult intensive care.

Multicenter Study Comparative StudyThe use of end-tidal carbon dioxide monitoring to confirm endotracheal tube placement in adult and paediatric intensive care units in Australia and New Zealand.
The use of end-tidal carbon dioxide monitoring to assist in confirming endotracheal tube placement is currently not mandatory in intensive care units (ICUs) in Australia and New Zealand. Early detection of failed tracheal intubation is vital to optimize management and to prevent complications. Questionnaires were sent to the lead clinician/head of department of all 66 intensive care units approved for training purposes by the Joint Faculty of Intensive Care Medicine in Australia and New Zealand. ⋯ Thirty-eight respondents (62.3%) thought that end-tidal carbon dioxide monitoring should be mandatory to confirm tracheal intubation in the intensive care unit. If it were available, 42 respondents (68.8%) would use end-tidal carbon dioxide monitoring for confirmation of every intubation. Mandatory end-tidal carbon dioxide confirmation of endotracheal tube placement was policy in 33 (54.1%) of the intensive care units.

Randomized Controlled Trial Clinical TrialGum elastic bougie-guided insertion of the ProSeal Laryngeal Mask Airway.
We tested the hypothesis that gum elastic-bougie-guided insertion of the ProSeal Laryngeal Mask Airway is more frequently successful than introducer tool guided insertion after failed digital insertion. One hundred anaesthetized patients (ASA 1-2, aged 18 to 80 years) were randomized for the second insertion attempt using either the gum elastic bougie-guided or introducer tool techniques. The bougie-guided technique involved priming the drain tube with the bougie, placing the bougie in the oesophagus using laryngoscope guidance, digital insertion along the palato-pharyngeal curve, and bougie removal. ⋯ The aetiology of failed insertion was similar for the digital and introducer tool techniques in 94% (33/35) of patients. There was no blood staining on the bougie, laryngoscope or introducer tool at removal, but blood staining was more common on the ProSeal Laryngeal Mask Airway with the introducer tool technique (9/50 vs 2/50, P=0.03). We conclude that the gum elastic bougie-guided insertion has a higher success rate and causes less trauma than the insertion tool insertion technique after failed digital insertion of the ProSeal Laryngeal Mask Airway.

Comparative StudyDelayed epidural catheter removal: the impact of postoperative coagulopathy.
A retrospective analysis of 413 patients who received postoperative epidural analgesia under a standardized protocol found that 84 (20%) had a duration of epidural catheterization of greater than four days. The most common reasons were significant pain (n=64, 15%) and coagulopathy (n=26, 6%). Risk factor analysis for coagulopathy showed an odds ratio of 10.1 (95% confidence interval 4.2-24.5) for prolonged epidural catheterization among patients undergoing hepatectomy. ⋯ The signs soon resolved in all except two, one of whom had neuropathy related to intraoperative positioning and the other preoperative weakness. Accidental epidural catheter dislodgement occurred in 29 patients (7%) and is potentially hazardous if coagulopathy is unresolved. The risk-benefit ratio and factors complicating catheter removal, especially coagulopathy, should be considered when deciding whether to use epidural techniques.
