Critically ill infants are subjected to many painful experiences that, if inadequately treated, can have severe physiological and psychological consequences. Optimal management of pain relies on the adequacy of nurses' assessment; this, however, is complicated by another common condition, agitation. A multidimensional assessment is therefore necessary to adequately identify pain and agitation. ⋯ Nurses used cues specific to the critically ill rather than the less sick infant. Results of this study also show the difficulty of differentiating between pain and agitation. Further research on ways of distinguishing between the construct of pain and agitation needs to be undertaken.

Turning a ventilated patient into the prone position can greatly enhance arterial blood oxygenation independent of ventilator parameters. This article explores the physiology relating to pulmonary ventilation, highlighting an overall improvement in ventilation/perfusion matching as a result of the prone position. A series of small studies seems to suggest that prone positioning can have a dramatic effect on life-threatening hypoxia, including adult respiratory distress syndrome (ARDS) but as yet there have been no large, randomised, multi-centre trials to put beyond doubt the benefits of prone ventilation. ⋯ Many are practical problems and the article goes on to explore a variety of these, including turning and positioning the patient, emergencies and access and the psychological effects of being in the prone position. It is important that nurses understand the physiological basis for any actions, including turning the patient prone, but it is also important that nurses doctors and other professionals appreciate the practical difficulties that this form of management can produce. All team members must work together to ensure a safe, cohesive approach to turning and caring for the ventilated patient in the prone position.

Secondary brain injury is associated with a reduction in cerebral blood flow, oxygenation and perfusion related to hypotension, hypoxemia and raised intracranial pressure. This has been confirmed on autopsy and is associated with a higher mortality rate, as supported by many studies. The primary goal of nursing management in severe head trauma is to maintain adequate cerebral perfusion and improve cerebral blood flow in order to prevent cerebral ischaemia and secondary injury to the brain. ⋯ The majority of the evidence was derived from class II and class III classifications, which provide guidelines and options for practice. Nursing and medical management were found to overlap, with the focus for the nurse being an integrated balance of scientific, technical and humanistic management. The nurse's role is extremely important because the expert nurse cognitively manipulates many variables over a continuum of care and, if such tasks are skillfully and successfully performed, the incidence of secondary brain injury is reduced.

The medical emergency team (MET) at Liverpool Hospital superseded the cardiac arrest team in 1990 and can be summoned by any staff member who identifies a patient at risk according to preset criteria; for example, severe hypotension. Weekly reviews of MET calls have identified clinical antecedents present prior to the patient's condition deteriorating to a critical level. This study assessed the responses of nurses in the presence of these warning signs. ⋯ The predominant response to a clinical antecedent was to call the MET (68.4 per cent). Other responses resulted in delays of 1 hour (18 per cent) and up to 3 hours (8 per cent) on some wards before treatment specific to the clinical antecedent commenced. A need to educate health professionals regarding the warning signs of acute severe illness and when to summon assistance has been identified.

Technological advances in health care have made it possible to restore and prolong life for patients who would have died in the past. Unfortunately, one consequence of this is that some patients linger in intensive care units (ICUs), dependent on the technologies but with no hope of recovery. Therefore, decisions regarding withdrawal of life-support treatment are increasingly being faced by the health-care team. ⋯ The study highlighted the importance of honest communication during the processes of decision-making and withdrawal of treatment. It was important for these nurses to be sure that family members were well-informed regarding the process of withdrawal of life-support treatment and that they could provide support and ensure that the patient's comfort and dignity were maintained during the process. The need to debrief after the event became evident but formal debriefing processes were rarely undertaken.
