High-dose mannitol effectively reduces mortality in acute intracranial hematoma patients. Evidence is limited for continuous mannitol infusion in non-operable cases, but it may improve survival compared to pentobarbital.

Area of Science:

  • Neuroscience
  • Critical Care Medicine
  • Pharmacology

Background:

  • Mannitol is used for acute brain swelling but its long-term efficacy in severe head injury is debated.
  • Prolonged mannitol dosage may lead to increased intracranial pressure due to reverse osmotic shifts.

Purpose of the Study:

  • To evaluate different mannitol therapy regimens for acute traumatic brain injury.
  • To compare mannitol with other intracranial pressure (ICP) lowering agents.
  • To assess mannitol's effectiveness at various stages post-injury.

Main Methods:

  • Systematic review of randomized controlled trials (RCTs) on mannitol in acute traumatic brain injury.
  • Searches included reference lists and author communications.
  • Data extraction and quality assessment by independent reviewers; relative risks (RR) and 95% confidence intervals (CI) calculated.

Main Results:

  • High-dose mannitol reduced mortality (RR=0.55) and death/severe disability (RR=0.58) compared to conventional doses in pre-operative intracranial hemorrhage management.
  • ICP-directed therapy showed a non-significant trend towards reduced mortality (RR=0.83) versus standard care.
  • Mannitol showed a non-significant trend towards reduced mortality (RR=0.85) compared to pentobarbital; pre-hospital use had insufficient data.

Conclusions:

  • High-dose mannitol is preferable to conventional-dose mannitol for pre-operative intracranial hematoma management.
  • Limited evidence exists for continuous mannitol infusion in non-operable raised ICP cases.
  • Mannitol may improve mortality over pentobarbital; ICP-directed therapy shows a small benefit.
