Intensive Care Unit (ICU) patients almost uniformly suffer from sleep disruption. Even though the role of sleep disturbances is not still adequately understood, they may be related to metabolic, immune, neurological and respiratory dysfunction and could worsen the quality of life after discharge. A harsh ICU environment, underlying disease, mechanical ventilation, pain and drugs are the main reasons that underlie sleep disruption in the critically ill. ⋯ Delirium is strongly related to increased ICU morbidity and mortality, thus the resolution of sleep disruption could significantly contribute to improved ICU outcomes. An early evaluation of delirium is strongly recommended because of the potential to resolve the underlying causes or to begin an appropriate therapy. Further studies are needed on the effects of strategies to promote sleep and on the evaluation of better sleep in clinical outcomes, particularly on the development of delirium.

Randomized Controlled Trial Multicenter Study Comparative StudySufentanil-propofol vs remifentanil-propofol during total intravenous anesthesia for neurosurgery. A multicentre study.
In a randomised, prospective multi-centre study, we compared the intraoperative and postoperative effects of two opioids: sufentanil and remifentanil, in combination with propofol in two groups of patients undergoing neurosurgery. ⋯ There were no significant differences between the groups in the duration of surgery and anesthesia, mean arterial pressure, heart rate, time to eye opening or extubation. The incidence of vomiting, respiratory depression and shivering was similar in both groups. Postoperative pain requiring supplemental analgesics was significantly lower in the sufentanil group (P<0.05). Although there were no significant differences between the groups in postoperative behavioural examinations by Rancho Los Amigos Test, patients anesthetised with sufentanil had significantly better Short Orientation-Memory-Concentration Test values at 15 and 180 min postoperatively (P<0.05). CONCLUSION. We conclude that remifentanil and sufentanil are suitable adjunct to propofol for total intravenous anesthesia (TIVA). Patients receiving sufentanil have reduced analgesic requirements and better cognitive function postoperatively than those who received remifentanil.

ReviewHypothermia for brain protection in the non-cardiac arrest patient.
This review focuses on the potential application of hypothermia in adults suffering traumatic brain injury (TBI). Hypothermia is neuroprotective, reducing the damaging effects of trauma to the brain in a variety of experimental situations, such as brain ischemia and brain injury, but it has failed to demonstrate outcome improvement in a major controlled, randomized trial. ⋯ However, evidence does suggest that hypothermia is effective in reducing intracranial hypertension after head injury. Since hypothermia has important side effects, further work is necessary before introducing this procedure into clinical practice for TBI.

A significant number of patients that have been critically ill require mechanical ventilation for extended periods of time as they progress towards recovery. Many of these patients can be cared for outside of the Intensive Care Unit in facilities focused on stabilizing the underlying medical problems, managing ventilatory support, and planning for rehabilitation and home care. ⋯ In the present article, a relevant literature review is presented concerning the outcome of patients undergoing prolonged mechanical ventilation. The main focus of the research was to address how to alleviate the burden of prolonged critical illness on mechanically ventilated patients who may eventually die after a great deal of suffering, and to identify the tangible emotional and financial costs to these patients, their families, and society.
