Hyperglycaemia upon onset of ICU-acquired bloodstream infection is associated with adverse outcome in a mixed ICU population.
This study aimed to assess whether a relationship exists between hyperglycaemia and outcome in a mixed cohort of critically ill patients with nosocomial bloodstream infection (BSI), and to evaluate patterns of blood glucose levels between survivors and non-survivors. A historical observational cohort study was conducted in the intensive care unit (ICU) of a tertiary care referral centre. One-hundred-and-thirty patients with a microbiologically documented ICU-acquired BSI (period 2003 to 2004) were included. ⋯ Multivariate logistic regression showed that APACHE II (P = 0.002), antibiotic resistance (P = 0.004) and hyperglycaemia (> or = 175 mg/dl) upon onset of BSI (P = 0.017) were independently associated with in-hospital mortality, whereas a history of diabetes (P = 0.041) was associated with better outcome. Hyperglycaemia (> or = 175 mg/dl) upon onset of ICU-acquired BSI is associated with worse outcome in a heterogeneous ICU population. Patterns of morning blood glucose levels have only limited value in the prediction of the individual course.

Safety of percutaneous tracheostomy in obese critically ill patients: a prospective cohort study.
Obesity has been described as a relative contraindication for percutaneous tracheostomy. The objective of our study was to examine the safety and complications of percutaneous tracheostomy in obese patients. We conducted a prospective cohort study of all consecutive patients who underwent percutaneous tracheostomy at a tertiary medical-surgical intensive care unit between May 2004 and October 2005. ⋯ Major complications were significantly higher in obese patients (12% vs. 2%, P = 0.04), while the rate of minor complications was not significantly different between the two groups. There were no instances of death or pneumothorax, subcutaneous emphysema or need for surgical intervention during or in the postoperative period in either group. Our study suggests that percutaneous tracheostomy can be performed safely in the majority of obese patients.

Review Case ReportsArterial gas embolism: a review of cases at Prince of Wales Hospital, Sydney, 1996 to 2006.
Arterial gas embolism may occur as a complication of diving or certain medical procedures. Although relatively rare, the consequences may be disastrous. Recent articles in the critical care literature suggest the non-hyperbaric medical community may not be aware of the role for hyperbaric oxygen therapy in non-diving related gas embolism. ⋯ Two remained severely affected with major neurological injury. Both had non-diving-related arterial gas embolism. There was a good outcome in the majority of patients who presented with arterial gas embolism and were treated with compression.

Case ReportsAnaesthesia for excision of an intraoral mass in a neonate: use of a laryngeal mask during removal of congenital epulis.
Congenital epulis is a rare intraoral tumour of the newborn arising from gingival mucosa, most commonly from the alveolar ridge. It may interfere with normal feeding or potentially compromise respiration. ⋯ The lesion was removed one day after delivery, under general anaesthesia using a laryngeal mask airway to control the infant's airway. The rationale for this management plan and alternatives to this strategy are discussed.
