Shivering management during therapeutic temperature modulation: nurses' perspective.
Therapeutic temperature modulation, which incorporates mild hypothermia and maintenance of normothermia, is being used to manage patients resuscitated after cardiac arrest. Methods of modulating temperature include intravenous infusion of cold fluids and surface or endovascular cooling. During this therapy, the shiver response is activated as a defense mechanism in response to an altered set-point temperature and causes metabolic and hemodynamic stress for patients. ⋯ Once shivering is detected, treatment is imperative to avoid deleterious effects. The Bedside Shivering Assessment Scale can be used to determine the efficacy of interventions intended to blunt thermoregulatory defenses and can provide continual evaluation of patients' responses to the interventions. Nurses' knowledge and understanding of the harmful effects of shivering are important to effect care and prevent injury associated with uncontrolled shivering.

National survey of central venous catheter flushing in the intensive care unit.
Evidence is needed on the best solution for flushing central venous catheters. ⋯ Flushing practices for central venous catheters vary widely. A randomized controlled trial is needed to determine the optimal flushing solution to maintain short-term patency.

The tele-intensive care unit (tele-ICU) uses sophisticated telemedicine technology and a remote team of critical care experts, including nurses, to provide continuous monitoring, assessment, and interventional services to a large number of patients across multiple ICUs. This new practice environment offers experienced critical care nurses an opportunity for career and knowledge expansion while reducing some of the physical and emotional risks encountered at the bedside. ⋯ The transition from the bedside into the tele-ICU role can be complex as tele-ICU nurses encounter ICU acceptance barriers and a lack of or a change in professional identity. A formal orientation program focused on competency is necessary for the successful transition from bedside nurse to tele-ICU nurse.
