Clinical Trial
The prediction of extubation success of postoperative neurosurgical patients using frequency-tidal volume ratios.
The process of discontinuing neurological patients from mechanical ventilation is still controversial. The aim of this study was to report the outcome from extubating patients undergoing elective craniotomy and correlate the result with the measured f/V (t) ratio. ⋯ The f/V (t) ratio does not predict extubation failure in patients who have undergone elective craniotomy. Patients who fail extubation present higher incidence of pneumonia, tracheostomy and higher mortality rate.

Temperature regulation in humans is controlled by the hypothalamus. After death by neurological criteria, the hypothalamus ceases to function and poikilothermia ensues. Preservation of normothermia in those patients destined to become organ donors is an important part of maintaining the normal physiology of the organs and organ systems. Typical means of achieving normothermia include increasing the temperature of the ambient air, infrared warming lights, instillation of warmed intravenous fluids, and warm air or water blankets. ⋯ Intravascular warming is a viable method for the maintenance of normothermia in organ donors. The experience here provides some insight into the ability of these devices to warm patients in other clinical situations.

No proven treatments exist for intracerebral hemorrhage (ICH). Carefully selected patients may benefit from surgery, and an international multicenter trial is ongoing. We sought to determine how many patients in a population-based ICH cohort would have been eligible for surgery using the Surgical Trial in Intracerebral Hemorrhage II (STICH II) criteria. ⋯ In this population-based ICH cohort, 7.7% (22 of 286) of ICH patients would have qualified for STICH II enrollment. Other treatment options need to be explored for most ICH patients.

Multicenter Study
Aggressive red blood cell transfusion: no association with improved outcomes for victims of isolated traumatic brain injury.
Clinical studies have caused blood transfusion practices in critically ill patients to become more conservative in the last decade. However, few studies have focused on trauma patients, particularly those with severe isolated traumatic brain injury. ⋯ Our results suggest that a restrictive transfusion practice is safe for severely head-injured patients.

To describe the reasons for and methods of resolution of ethics consultations conducted in neurological and neurointensive care units affiliated with a single health care facility. ⋯ Although there may be a role for ethics consultations in neurological practice, future studies are needed to better clarify how to optimize their use.
