Table 5.1. Treatment of elevated ICP
1. Elevation of head and relief of potential venous obstruction
2. Elevation of MAP (if appropriate)
3. PaCO2 of 30-35 mmHg, or 25-30 mmHg if there are signs of brain herniation
4. Mannitol 0.5-1.0 g/kg q. 6 h prn and furosemide 20 mg prn. Keep serum osmolality <320.
5. Maintain hypovolemia; monitor CVP, if possible.
6. Ventriculostomy for drainage of CSF, if applicable.
7. Sedation with opiates, benzodiazepines and/or propofol
8. Fine-tune the level of PEEP, if applicable.
9. Maintain normovolemia.
Aggressive measures (in patients refractory to conventional measures)
1. Induction of hypothermia to 33-34°C
2. Maximal EEG suppression with induction of propofol or barbiturate coma
3. Hyperventilation to PaCO2 of 20-25 mmHg (monitor SjvO2 or PbrO2)
4. Hypertonic saline (3% or 7.5% 25-50 ml/h); monitor serum sodium Extreme measures
1. Decompressive craniectomy
2. Excision of infarcted tissues ± lobectomy
This can be accomplished with maintenance of normovolemia and infusion of phenylephrine at 1-10 ^g/kg/min, or norepinephrine at 0.05-0.2 ^g/kg/min.
