Summary
Intravenous furosemide effectively controlled intracranial pressure in severely head-injured patients undergoing surgery. This diuretic may improve cerebral microcirculation by reducing cerebrospinal fluid production and astroglial swelling.
Area of Science:
- Neurosurgery
- Neurology
- Pharmacology
Background:
- Elevated intracranial pressure (ICP) is a critical complication in severe head injuries.
- Managing ICP is crucial for preventing secondary brain damage and improving patient outcomes.
Purpose of the Study:
- To evaluate the efficacy of intravenous furosemide in controlling ICP in severely head-injured patients undergoing surgery for intracranial hematomas.
- To explore the potential mechanisms by which furosemide influences ICP and cerebral microcirculation.
Main Methods:
- Intravenous furosemide was administered to 15 severely head-injured patients undergoing surgery.
- ICP was monitored and maintained below 20 torr.
- Routine pharmacologic and mechanical procedures were employed concurrently.
Main Results:
- Intracranial pressure was successfully maintained below 20 torr in all patients.
- The control of ICP was attributed to diuresis, carbonic anhydrase inhibition, decreased cerebrospinal fluid production, and decreased central venous pressure.
- Furosemide's potential role in improving cerebral microcirculation via inhibition of astroglial swelling was suggested.
Conclusions:
- Intravenous furosemide is an effective adjunct in managing elevated ICP in severely head-injured patients undergoing neurosurgery.
- Furosemide's multifaceted mechanisms, including diuresis and potential effects on cerebral edema, contribute to ICP control.
- Further research is warranted to elucidate furosemide's impact on cerebral microcirculation in this patient population.
