The effects of indomethacin on intracranial pressure, cerebral

Acta neurochirurgica · Jan 1991

The effects of indomethacin on intracranial pressure, cerebral blood flow and cerebral metabolism in patients with severe head injury and intracranial hypertension.

In five head-injured patients with cerebral contusion and oedema in whom it was not possible to control intracranial pressure (ICP) (ICP greater than 20 mmHg) by artificial hyperventilation (PaCO2 level 3.5-4.0 kPa) and barbiturate sedation, indomethacin was used as a vasoconstrictor drug. In all patients, indomethacin (a bolus injection of 30 mg, followed by 30 mg/h for seven hours) reduced ICP below 20 mmHg for several hours. Studies of cerebral circulation and metabolism during indomethacin treatment showed a decrease in CBF at 2 h. ⋯ In the other patients a return of ICP and CBF to pretreatment levels was observed. In all patients indomethacin treatment was followed by a fall in rectal temperature. These results suggest that indomethacin due to its cerebral vasoconstrictor and antipyretic effect should be considered as an alternative for treatment of ICP-hypertension in head-injured patients.

AbstractIn five head-injured patients with cerebral contusion and oedema in whom it was not possible to control intracranial pressure (ICP) (ICP greater than 20 mmHg) by artificial hyperventilation (PaCO2 level 3.5-4.0 kPa) and barbiturate sedation, indomethacin was used as a vasoconstrictor drug. In all patients, indomethacin (a bolus injection of 30 mg, followed by 30 mg/h for seven hours) reduced ICP below 20 mmHg for several hours. Studies of cerebral circulation and metabolism during indomethacin treatment showed a decrease in CBF at 2 h. After 7 h, ICP remained below 20 mmHg in three patients, and these still had reduced CBF. In the other patients a return of ICP and CBF to pretreatment levels was observed. In all patients indomethacin treatment was followed by a fall in rectal temperature. These results suggest that indomethacin due to its cerebral vasoconstrictor and antipyretic effect should be considered as an alternative for treatment of ICP-hypertension in head-injured patients.
