Neurocritical care
-
Acute ischemic stroke is a neurological emergency that can be treated with time-sensitive interventions, including intravenous thrombolysis and endovascular approaches. Extensive study has demonstrated that rapid assessment and treatment are essential for improving neurological outcome. For this reason, acute ischemic stroke was chosen as an Emergency Neurological Life Support protocol. The protocol focuses on the first hour following the onset of neurological deficit.

Intracerebral hemorrhage (ICH) is a subset of stroke due to bleeding within the parenchyma of the brain. It is potentially lethal, and survival depends on ensuring an adequate airway, reversal of coagulopathy, and proper diagnosis. ICH was chosen as an Emergency Neurological Life Support protocol because intervention within the first critical hour may improve outcome, and it is critical to have site-specific protocols to drive care quickly and efficiently.

Acute non-traumatic weakness may be life threatening if it involves the respiratory muscles or is associated with autonomic dysfunction. Most patients presenting with acute muscle weakness have a worsening neurological disorder that requires a rapid, systematic evaluation, and detailed neurological exam to localize the disorder. ⋯ Causes of acute non-traumatic weakness are discussed by both presenting clinical signs and anatomical location. For each diagnosis, key features of the history, examination, investigations, and treatment are outlined in the included tables.
-
Subarachnoid hemorrhage (SAH) is a neurological emergency because it may lead to sudden neurological decline and death and, depending on the cause, has treatment options that can return a patient to normal. Because there are interventions that can be life-saving in the first hour of onset, SAH was chosen as an Emergency Neurological Life Support protocol.

Decompressive craniectomy (DC) has been used for many years in the management of patients with elevated intracranial pressure and cerebral edema. Ongoing clinical trials are investigating the clinical and cost effectiveness of DC in trauma and stroke. While DC has demonstrable efficacy in saving life, it is accompanied by a myriad of non-trivial complications that have been inadequately highlighted in prospective clinical trials. ⋯ Overall, one of every ten patients undergoing DC may suffer a complication necessitating additional medical and/or neurosurgical intervention. While DC has received increased attention as a potential therapeutic option in a variety of situations, like any surgical procedure, DC is not without risk. Neurologists and neurosurgeons must be aware of all the potential complications of DC in order to properly advise their patients.
