Wireless communication and data transmission are playing an increasing role in the critical care environment. Early anecdotal reports of electromagnetic interference (EMI) with intensive care unit (ICU) equipment resulted in many institutions banning these devices. ⋯ Restrictions to the use of mobile devices are being lifted, and it has been suggested that the benefits of improved communication may outweigh the small risks. However, increased use of cellular phones and ever changing communication technologies require ongoing vigilance by healthcare device manufacturers, hospitals and device users, to prevent potentially hazardous events due to EMI.

Improvements in the outcome of children with meningococcal disease.
Recent years have seen a marked reduction in the mortality of children with meningococcal disease in paediatric intensive care units (PICU); the reasons for this improvement are multifactorial. The mortality rates for critically ill children overall have improved and reasons for this are probably increased centralisation of PICU services and that fewer critically ill children are now looked after on adult units. Specific treatment pathways for sepsis have improved with the publication of clinical guidelines for children and initiatives such as the Surviving Sepsis Campaign. There is a continuing need to focus on the care delivered to children before reaching PICU and to minimise the morbidity suffered by survivors of this disease.

A body of knowledge exists to suggest an association between nurse staffing and adverse patient outcomes. Hugonnet and colleagues add further evidence by linking nurse staffing to late-onset ventilator-associated pneumonia. Discussed are a number of concerns surrounding the analytic component of this study, including the construction of variables and the statistical models. The authors' estimation that hospitals maintaining a nurse-to-patient ratio above 2.2 could decrease the risk of health care associated infections is based on findings that are potentially biased and unrealistic.

Why is the practice of intensive care so heterogenous? Uncertainty as to 'best practice', conservatism, and complacency may all contribute to our divergent management strategies. The need for further generalisable research, anonymised audit, external peer review and open access databases is discussed.

Corticosteroids to prevent postextubation upper airway obstruction: the evidence mounts.
Intubation of the airway can lead to laryngotracheal injury, resulting in extubation failure from upper airway obstruction (UAO). A number of factors can help to identify patients who are at greatest risk for postextubation UAO. Three randomized controlled trials demonstrate that prophylactic corticosteroids decrease the risk for postextubation UAO and probably the need for re-intubation.
