In the United States, a head injury...

In the United States, a head injury flash on the minds every seven seconds and an associated death each five minutes. This affects 200000 folks per year.(1) Almost half of all trauma deaths are fit to head injuries. Equally important is the fact that an uniform larger number of patients with brain injuries--most young and otherwise healthy--are left permanently disabled.(2) An estimated 60% of trauma fatalities come to pass before patients can be admitted to the hospital (ie, 40% at the spectacle 20% in the emergency department). Brain injuries present itself at all ages, but the peak is in young adults between the ages of 15 and 24 years antique with men affected three to four times more frequently than women.(3) The cost of head injuries in times of expense and human misery is go beyonded by few other conditions.

Major strides have been made during the past three decades in reducing the morbidity and mortality of stern head injury from 50% in 1970 to approximately 36% in the 1980s(4) These issues correlate to larger availability and better application of conjuncture medical services and critical care methodologies.(5) In addition, health care providers at the Legacy Emanuel Hospital and Health Center trauma center in Portland, Ore, have noted a dramatic decrease in the incidence of head injury with the enforcement of seat belt and helmet laws.

THE GLASGOW COMA SCALE

From the storming head injury diagnosis and management are linked to patient issues Using the Glasgow Coma Scale (GCS) 80% of all head injuries are classified as mild (ie, GC score between 13 and 15) 10% are classified as moderate (ie, GC score between nine and 12) and the remaining 10% are classified as austere scoring eight or less onward the GCS (Figure 1).(6) A GC score of eight or les has become the accepted definition of a comatose patient.(7) A GC score of three four, or five leads to a mortality rate of 76% as chiefly patients scoring so low have unrelenting cerebral compression and displacement with temporal lobe-tentorial herniation.(8) Patients with accurate head injuries have fixed and dilated pupils, exhibit posturing, are unable to succeed simple commands, and are insensitive to pain, smooth after cardiopulmonary stabilization. With these patients, a "wait and see" approach can be disastrous--prompt diagnosis and treatment are of best importance.

When routine measures fail to alleviate cerebral swelling associated with traumatic brain injury, caregivers have not many management options. Patients most many times will die or survive in an extremely disabled state. Despite advances in understanding, monitoring, and treating cerebral hypertension, the result for patients with severe diffuse post-traumatic Cerebral edema remains poor.(9)

MANAGING exact HEAD INJURIES

greatest in number strategies for managing head injury rely in succession minimizing secondary brain injury by means of lowering intracranial pressure (ICP) and optimizing cerebral perfusion crushing (CPP) to greater than 70 mm Hg (Table 1)(10) Numerous studies report a significant correlation between elevated ICP and gentle CPP with poor outcomes. (11) As elevated ICP is a major predictor of mortality, it is logical that caregivers' maximum effort be directed toward preventing intracranial hypertension and optimizing CPP Treatment options to achieve this include evacuating intracranial masses, using patient positioning, draining cerebral spinal fluid, administering osmotic diuretics, using vasopressors, inducing coma with barbiturates, and performing decompressive craniectomy.

ADULT strict BRAIN INJURY MANAGEMENT

Purpose

To standardize care of the fiercely brain injured patient from pinch room to hospital discharge, making use of the Brain Trauma Foundation 1995 Guidelines for the Management of exact Head Injury and the trauma collaborative practice plan. Standardization of care will allow the greatest in number efficient application of predetermined therapies and interventions from all responsible staff members. Standardization also will allow potential efficacy or harm of recently made known and/or experimental treatment regimens to become more clearly apparent.

I. crisis department

A. Oxygenation

1 Targets: Oxygen saturation by the agency of pulse oximeter [is greater than] 95%/partial hurry of oxygen [is greater than] 70 mm Hg)

2 Methods

a) Patients with Glasgow Coma Scale (GCS) [is les than] 8 should be intubated in the field, en way or as shortly after arrival as is practical.

b) A GC [is greater than] 9: Oxygen supplementation from mask or nasal cannula.

c) A GC between 9 and 12: Monitor carefully for decreasing plain of consciousness, ability to maintain airway, or altered respiratory pattern. Be prepared to intubate patient.

3 Monitors

a) pulsation oximeter on all patients.

b) Arterial vital fluid gases by femoral artery small hole by intern on arrival.

c) Arterial cannulation for all patients with GC [is les than] 8 or in brunt at any time, or placed onward mechanical ventilation for reasons other than behavior control

B Ventilation (partial press of carbon dioxide [Pa[C0.sup.2]]): Exces hyperventilation when used "prophylactically," worsens issue at three and six month Normocarbia should be maintained in the absence of clinical evidence of herniation or cerebral edema (eg pupillary dilatation or asymmetric reactivity, motor posturing, GC [is les than] 6)
