Mild Head Injury GCS 14 -15

Mild head injury patients usually do not lose consciousness but neurologic function or decreased consciousness without causing other damage to the GCS: 15
Patofisiologi The brain would be functioning very well what if the need for oxygen and glucose are met, because the energy produced in the cells - nerve cells almost entirely through the process of oxidation. The brain does not have a reserve of oxygen, so a lack of blood flow to the brain, although for a while will cause malfunction. Similarly, the need for oxygen as fuel for brain metabolism can not be less than 20 mg% as it would lead to coma, glucose needs as much as 25% of the total needs of the body, so that when the plasma oxygen levels dropped to 70% will be symptom - symptom onset cerebral dysfunction. At the time of hypoxic brain, the body tries to meet the needs of oxygen through the process of anaerobic metabolism that can cause dilation of blood vessels. In the severe contusions, hypoxic brain damage will occur or the accumulation of lactic acid from anaerobic metabolism. This will cause the oxidation of anaerobic metabolism. This will cause acidosis metababolik. Under normal circumstances Cerebral Blood Flow (CBF) is 50-60 ml / min 100 gr. Brain tissue which is 15% of cardiac output.Trauma chief cause changes in heart function sekuncup atypical myocardial activity, changes in vascular pressure and pulmonary edema.
