T e most common mechanisms o injury or sci include motor vehicle accidents, alls, acts o violence, and sports injuries (fig. 15-4).40 while the relative distribution o these vary by nation and area, in general, motor vehicle accidents account or the majority, and when combined with these other our mechanisms comprise more than 90% o the external causes o traumatic spinal injury. For motor vehicle accidents resulting in traumatic sci, one study ound that 70% involved vehicle rollover, 75% o those injured were not wearing seatbelts, and 39% o those injured were ejected rom the vehicle during the accident.41 in many nations, these numbers are a ected by the high number o motorcycle riders and subsequent accidents, especially in those nations with lesser helmet sa ety laws. Spinal cord trauma can cause epidural hematomas, disc herniation, or bone legions that can damage or put pressure directly or indirectly on the spinal cord. I a patient is suspected o having sustained a traumatic sci, they should be evaluated immediately by emergency services at the point o injury and again 242 ch apt er 15 causes of traumatic spinal cord injury 7.00% 7.30% 35.90% 20.30% 29.50% motor vehicle accidents violence falls sports other/unknown ▲ figure 15-4 causes o spinal cord injury in the united states.39 while the relative contribution o various causes o spinal cord injury are di erent rom nation to nation and region to region and even year to year as a result o di erent sa ety laws, customs, and other considerations, motor vehicle accidents, violence, alls, and sports represent the most prevalent causes o traumatic sci worldwide. Upon delivery to the hospital emergency department. T is assessment should ollow a ls protocol, initiating within an evaluation o the individual’s airway, breathing, and circulation, ollowed by assessment o disability and exposure (abcde). Following this, the spine should be inspected or swelling, bruising, or de ormity to determine the location o injury as quickly and accurately as possible. In order to prevent urther injury and maintain spinal cord stability, patients with suspected traumatic sci should only be log-rolled in order to inspect the back. Clinicians should recognize that many patients who sustain traumatic sci o en have coexisting injuries, which also require care ul recognition, stabilization, and treatment. Following inspection o the back, a nal ull neurological assessment and classi cation o the injury should be made. T is should include testing or reaction to light touch, pin prick, and the presence o voluntary anal contraction. T ere are a variety o tools or this, including the otal motor score, the frankel scale, and the american spinal association (asia) impairment scale (ais). O these, the ais is the most commonly employed in clinical practice (fig. 15-5). An important caveat to the ais is that, while it di erentiates between incomplete and complete sci based on the activity o the sacral nerve, any patient with motor or sensory unction below the level o injury should be considered to have an incomplete sci, as the preservation o such control indicates the unctional maintenance o long white matter tracts through the level o injury. T e tracking o the recovery and progress o those who have su ered an sci is important to both the rehabilitation o the individual as well as the evolution o e ective treatment in the global population.

Acute respiratory acidosis should be treated with naloxone in the case o opiod ingestion and umazenil in the case o benzodiazepine ingestion. Acute uremia in the setting o hypovolemia should be treated aggressively with iv uids and in the setting o chronic kidney disease with dialysis. I neuroimaging is negative or an acute intracranial process, then urther ancillary testing should be considered. Routine or ceeg should be obtained to rule out convulsive or nonconvulsive status epilepticus. I eeg reveals status epilepticus, give iv lorazepam (2 mg every 3–5 minutes, maximum dose 0.1 mg/kg). I no response to lorazepam, administer iv osphenytion (20 pe/kg over 30 minutes). I no response to osphenytoin, consider administration o a second antiepileptic (lacosamide, levetiracetam, valproic acid) or continuous iv in usion o a sedative/hypnotic (midazolam, propo ol), titrated to a burst suppression pattern on eeg. In re ractory status epilepticus, pentobarbital, therapeutic hypothermia, and nondepolarizing muscle agents can be considered. I ebrile, the patient should undergo urgent lumbar puncture to assess spinal uid or in ectious etiologies. I csf is suspicious or meningitis, initiation o broad-spectrum antibiotic and antiviral therapy should be per ormed (ce riaxone, vancomycin, ampicillin, and acyclovir) i neuroimaging reveals evidence o a large intracranial structural lesion (compressive or destructive), interventions to reduce icp should be per ormed as ollows. Elevation o the head o the bed to 30 degrees.

In patients with hemorrhage (edh, sdh, ich, ivh, sah), correction o underlying coagulopathies and e ective blood pressure reduction (goal o 140 mmhg systolic). In cerebral venous sinus thrombosis, treatment with iv un ractionated heparin should be initiated. In acute obstructive hydrocephalus, ventriculostomy placement should be considered (contraindicated in cerebellar mass lesions due to upward herniation risk). In speci c situations such as in large cortical ich, ruptured avm, and malignant mca in arction, acute hematoma evacuation and decompressive craniectomy should be considered. What is the general approach to the xt care o the comatose patient in the neurocritical care unit?. Following stabilization o the comatose patient, it is important to appropriately manage all associated complications. Rans er o the patient to the most readily available neurocritical care unit will provide the greatest probability or a good neurologic outcome. He approach o a neurointensivist to the management o coma is through a detailed and systematic process. On a daily basis, all organ systems are careully examined and treated appropriately. Although speci ic system-based interventions are out o the scope o this chapter, the general approach to the management o the patient should be ollowed as shown (table 36-8). Prognosis and long-term care of the comatose patient c as e 36-8 a 70-year-old man admitted to the hospital su ers acute cardiopulmonary arrest. Return o spontaneous circulation is achieved a ter 15 minutes. A hypothermia protocol is initiated, and neurology is consulted or prognosis. Twenty- our hours a ter arrest, the patient begins to demonstrate myoclonic status epilepticus. Neurologic examination shows absent pupillary responses, positive corneal responses, and no motor response to stimuli. On day 3, the patient continues to show absence o all pupillary ref exes and motor responses. A discussion is had with the amily that given speci c examination ndings, the probability or a good neurologic outcome is low. The amily makes the decision to withdraw care. Survivability and prognosis in coma are ar more di cult to predict than most typical medical diagnoses.
