Neurocritical care
-
In neurocritically ill patients, one early mechanism behind secondary brain injury is low systemic blood pressure resulting in inadequate cerebral perfusion and consequent hypoxia. Intuitively, higher partial pressures of arterial oxygen (PaO2) could be protective in case of inadequate cerebral circulation related to hemodynamic instability. ⋯ During the first 24 h of ICU treatment in mechanically ventilated brain injured patients, the association between PaO2 and mortality was not different in patients with low compared to normal MAP.

We talk, text, email all day. Do we perceive things correctly? Do we need to improve the way we communicate? It is a truism that providing insufficient information about a patient results in delays and errors in management. How can we best communicate urgent triage or urgent changes in the patient condition? There is no substitute for a face-to-face conversation but what would the receiving end want to know? One starting point for those practicing acute neurology and neurocritical care is a new mnemonic TELL ME (Time course, Essence, Laboratory, Life-sustaining interventions, Management, Expectation), which will assist physicians in standardizing their communication skills before they start a conversation or pick up a phone. ⋯ Perfect orchestration in communication may be too much to ask, but we neurointensivists strive to convey information accurately and completely. Communication must be taught, learned, and practiced. This article provides guiding principles for a number of scenarios involving communication inside and outside the hospital.

Do-not-resuscitate (DNR) orders are commonly used after intracerebral hemorrhage (ICH) and have been shown to be a predictor of mortality independent of disease severity. We determined the frequency of early DNR orders in ICH patients and whether a previously reported association with increased mortality still exists. ⋯ The use of early DNR orders for ICH continues to be a strong predictor of in-hospital mortality. However, patients treated at hospitals with an overall high or low use of early DNR had similar relative risks of death whether or not there was an early DNR order, suggesting that such orders may not be a proxy for less aggressive care as seen previously.

The present study considers patients with spontaneous intracerebral hemorrhage (ICH) admitted to the neurocritical care unit (NCCU) through the Emergency Department (ED). It aims to identify patient-specific clinical variables that can be assessed on presentation and that are associated with prolonged NCCU length of stay (LOS). ⋯ We propose an ICH-LOS model based on neurosurgical intervention, intubation status and GCS at presentation to predict prolonged LOS in the NCCU in patients with ICH. This simple clinical tool, if prospectively validated, could help with medical planning, contribute to patient care-directed conversations, assist in optimizing hospital resource utilization, and, more importantly, motivating patient-specific interventions aimed at optimizing outcomes and decreasing LOS.
