The Lund concept offers a therapeutic strategy for elevated intracranial pressure (ICP) by managing intracranial volume. This approach focuses on reducing stress, capillary pressure, and cerebral blood volume, with favorable clinical outcomes.

Area of Science:

  • Neuroscience
  • Physiology
  • Critical Care Medicine

Background:

  • Sustained increase in intracranial pressure (ICP) presents complex therapeutic challenges.
  • The blood-brain barrier (BBB) plays a crucial role in regulating brain volume via controlled water and solute exchange.
  • Disruption of the BBB alters transcapillary water dynamics, influenced by hydrostatic and colloid osmotic pressures.

Purpose of the Study:

  • To present the "Lund concept" as a physiological approach to managing elevated ICP.
  • To outline the four key components of the Lund concept treatment protocol.
  • To review the efficacy of the Lund concept based on experimental and clinical evidence.

Main Methods:

  • The Lund concept involves four strategic interventions: reducing stress response and cerebral metabolism, lowering capillary hydrostatic pressure, maintaining colloid osmotic pressure and fluid balance, and decreasing cerebral blood volume.

  • Efficacy was assessed through experimental studies and clinical evaluations.
  • Intracerebral microdialysis was utilized to examine physiological and biochemical effects.

    • Main Results:

    • Experimental and clinical studies demonstrated the physiological and biochemical effects of the Lund concept.
    • The treatment protocol showed positive impacts on intracranial pressure management.
    • Clinical experiences with the Lund concept have been favorable.

    Conclusions:

    • The Lund concept provides a structured, physiologically-based therapeutic framework for managing elevated ICP.
    • The protocol addresses key factors influencing intracranial volume regulation.
    • Favorable clinical outcomes suggest the Lund concept is an effective treatment strategy for sustained increases in ICP.
