Current opinion in critical care

The management of sepsis and the multiple organ dysfunction syndrome has traditionally been centered on dysfunction of organs other than the brain (e.g., heart, lungs, or kidneys), although the brain is one of the most prevalent organs involved. Recent studies indicate that nonpulmonary acute organ dysfunction may contribute significantly to mortality and other important clinical outcomes. Acute confusional states (delirium) occur in 10 to 60% of the older hospitalized population and in 60 to 80% of patients in the intensive care unit, yet go unrecognized by the managing physicians and nurses in 32 to 66% of cases. Delirium is an important independent prognostic determinant of hospital outcomes, including duration of mechanical ventilation, nursing home placement, functional decline, and death. Recently, new monitoring instruments have been validated for monitoring of delirium in noncommunicative patients receiving mechanical ventilation. Hence, critical care physicians and nurses should routinely assess their patients for delirium and develop strategies for its prevention and treatment. ⋯ Delirium is extremely common and has significant prognostic implications in critically ill patients. Routine monitoring and a multimodal approach to prevent or reduce the prevalence of delirium are of paramount importance.

ReviewRecent developments in percutaneous tracheostomy: improving techniques and expanding roles.
The purpose of this review is to provide an update of recent developments pertaining to the use of percutaneous tracheostomy. Percutaneous tracheostomy has been established as an alternative to open surgical tracheostomy, but many key questions about the optimal use of this procedure remain unanswered. ⋯ Recent literature suggests that percutaneous tracheostomy is safe to use in an expanding population of patients, including patients with airway compromise and thrombocytopenia. Several methods seem to be safe alternatives to that originally described. Capnography has arisen as an alternative to bronchoscopy for confirmation of tracheal puncture. Recent evidence highlights that although tracheostomy may improve short-term outcome, these critically ill patients have a significant long-term risk of poor outcome. This must be taken into consideration when this procedure is offered.

To investigate the impact of critical illness polyneuropathy and critical illness myopathy on short-term and long-term patient outcome. ⋯ Intensive care unit-acquired critical illness polyneuropathy and critical illness myopathy influence the evaluation of acutely ill comatose patients and may instigate unreasonably pessimistic prognosis. Critical illness polyneuropathy and critical illness myopathy are an important cause of difficult weaning of patients from the ventilator and of persisting muscle weakness and disability after intensive care unit discharge.
