PRIMARY SURVEY AND RESUSCITATION 117<br />

observation in unit capable of close nursing observation<br />

and frequent neurological reassessment for at least the<br />

first 12 to 24 hours. A follow-up CT scan within 24 hours<br />

is recommended if the initial CT scan is abnormal or<br />

the patient’s neurological status deteriorates.<br />

Management of Severe Brain Injury<br />

(GCS Score 3–8)<br />

Approximately 10% of patients with brain injury who<br />

are treated in the ED have a severe injury. Such patients<br />

are unable to follow simple commands, even after<br />

cardiopulmonary stabilization. Although severe TBI<br />

includes a wide spectrum of brain injury, it identifies<br />

the patients who are at greatest risk of suffering<br />

significant morbidity and mortality. A “wait and see”<br />

approach in such patients can be disastrous, and prompt<br />

diagnosis and treatment are extremely important.<br />

Do not delay patient transfer in order to obtain a<br />

CT scan.<br />

The initial management of severe brain injury is<br />

outlined in (n FIGURE 6-11). (Also see Initial Management<br />

On admission to the ED, obtain a brief history and<br />

ensure cardiopulmonary stability before neurological<br />

assessment. Obtain a CT scan of the head and contact a<br />

neurosurgeon or a trauma center if transfer is necessary.<br />

All patients with moderate TBI require admission for<br />

PREVENTION<br />

Primary Survey and<br />

Resuscitation<br />

Brain injury often is adversely affected by secondary<br />

insults. The mortality rate for patients with severe brain<br />

injury who have hypotension on admission is more than<br />

double that of patients who do not have hypotension.<br />

The presence of hypoxia in addition to hypotension<br />

is associated with an increase in the relative risk of<br />

mortality of 75%. It is imperative to rapidly achieve<br />

cardiopulmonary stabilization in patients with severe<br />

brain injury. n BOX 6-2 outlines the priorities of the<br />

initial evaluation and triage of patients with severe<br />

brain injuries. (Also see Appendix G: Disability Skills.)<br />

A patient with a<br />

GCS score of 12<br />

deteriorates to a<br />

GCS score of 9.<br />

• Reevaluate the patient<br />

frequently to detect any<br />

decline in mental status.<br />

• Use narcotics and sedatives<br />

cautiously.<br />

• When necessary, use<br />

blood gas monitoring or<br />

capnography to ensure<br />

adequate ventilation.<br />

• Intubate the patient when<br />

ventilation is inadequate.<br />

Airway and Breathing<br />

Transient respiratory arrest and hypoxia are common<br />

with severe brain injury and can cause secondary brain<br />

injury. Perform early endotracheal intubation in<br />

comatose patients.<br />

Ventilate the patient with 100% oxygen until blood<br />

gas measurements are obtained, and then make<br />

appropriate adjustments to the fraction of inspired<br />

oxygen (FIO2). Pulse oximetry is a useful adjunct,<br />

and oxygen saturations of > 98% are desirable. Set<br />
