Randomized Controlled Trial Comparative Study Clinical TrialGastric emptying following brain injury: effects of choice of sedation and intracranial pressure.
To compare the effects of opioid and non-opioid sedation on gastric emptying. ⋯ Gastric emptying is not improved in patients with brain injury by avoiding morphine (1-8 mg/h) in the sedative regimen. Intracranial hypertension is associated with reduced gastric emptying.

Comparative Study
Reduction of post-traumatic intracranial hypertension by hypertonic/hyperoncotic saline/dextran and hypertonic mannitol.
Cerebral injury is seen in one of three patients with multiple traumas; thus efficient shock treatment is a most important measure against the development of secondary brain damage. Small-volume resuscitation in severe hemorrhagic shock by hypertonic/hyperoncotic saline/dextran has been shown to instantaneously normalize cardiac output and to raise systemic blood pressure. In this study, the fluid regimen was compared with hypertonic mannitol to investigate their therapeutic efficacy in intracranial hypertension. ⋯ The increase of the cerebral water content of the traumatized hemisphere was associated with a respective increase of the cerebral Na+ content and a (nonsignificant) decrease of the K+ content. The present findings demonstrate that the hypertonic/hyperoncotic saline/dextran was as efficient as the mannitol in reducing ICP that had been increased by a cerebral lesion and a space-occupying mass; the underlying mechanisms responsible for the reduction might differ. Because of the powerful hemodynamic properties of the saline/dextran in circulatory shock, administration of the solution in patients with multiple traumas and head injury might be particularly advantageous for the prevention of secondary ischemic brain damage.

Prediction of outcome in severe head injury based on recognition of sleep related activity in the polygraphic electroencephalogram.
This study shows that the continuing presence of activity similar to normal sleep in the EEG in conjunction with the EEG polygraph (EEGP) can be used to determine the severity of brain damage after head injury. Recordings were taken within seven days of head injury from 154 unselected patients after resuscitation and emergency surgery. Sixteen patients with ongoing seizures were excluded. ⋯ The mean follow up was 21.5 months. Groups 2 and 3 were significantly associated with a good outcome and group 5 with death or a vegetative state. Comparison between the EEG/EEGP findings and the Glasgow coma scale at the time of the recording showed the EEG/EEGP to be the better predictor of outcome, particularly for individual patients.

Seventeen patients with posterior fossa extradural haematoma are presented. While 7 patients had acute course, 6 had subacute and 4 had chronic course. All patients had evidence of occipital injury. ⋯ All patients with subacute and chronic course had good outcome while 43% with acute course succumbed to death. Besides the initial clinical status the co-existing lesions signifying the increased severity of injury have influenced the mortality and quality of outcome. In presence of occipital fracture a careful observation and timely intervention are warranted.
