-Loss of consciousness is always less than 6 hours and is always accompanied by some degree of posttraumatic amnesia.
-No apparent structural injury
-May need to wake q2h to check LOC
- Not detected on scans!
--Concussion patients might be hospitalized overnight
Monitor for signs and symptoms of headache, dizziness, lethargy, irritability, emotional lability, fatigue, poor concentration, decreased attention span, intellectual dysfunction, memory difficulties.
The cause of these symptoms is caused by the brains need for increased energy so that it can heal, but the global decrease in blood flow decreases the fuel available to correct the abnormalities.
Is a late sign of increased intracranial pressure.
Sign of herniation, the shifting of the brain from on compartment of high pressure to one of low pressure, leading to brain death
Signs and Symptoms
-Widening pulse pressure
--Cushing recognized that the body's initial response to rising intracranial pressure is a rise in systolic blood pressure
The rising systolic pressure results in widened pulse pressures, bradycardia and irregular breathing.
the patient experience bradycardia because the body try to compensate and uses every last bit of their epinephrine to compensate for the changes. eventually, the there will be no more supply of the epinephrine and thus, the bradycardia. hope this help.
As intracranial pressure continues to increase, the patient's heart rate will increase, breathing will became shallow, periods of apnea will occur, and blood pressure will begin to fall
Eventually an agonal rhythm will develop as herniation begins, followed soon by cessation of brain stem activity, respiratory arrest and cardiac arrest
