Clinical Hemorheology and Microcirculation
|September 28, 2015
Summary
Monitoring intensive care unit patients is crucial. This review explores microcirculation assessment, including serum lactate limitations and newer diagnostic tools for better patient outcomes.
Area of Science:
- Critical Care Medicine
- Physiology
- Biomedical Engineering
Background:
- Microcirculation monitoring is vital for intensive care unit (ICU) patient outcomes.
- Microcirculatory disorders, including capillary flow issues and altered perfused vessel density, significantly impact patient prognosis.
- Serum lactate is a common but limited marker for microcirculatory alterations.
Purpose of the Study:
- To review clinical correlates of microcirculatory disorders in critically ill patients.
- To provide an overview of novel diagnostic devices for evaluating microcirculation.
- To highlight the importance of microcirculation assessment for guiding individualized patient therapy.
Main Methods:
- Review of existing literature on microcirculation assessment in ICUs.
- Evaluation of clinical parameters and their correlation with microcirculatory dysfunction.
- Survey of emerging non-invasive diagnostic technologies for microvascular perfusion.
Main Results:
- Serum lactate has significant limitations in reflecting true microcirculatory status.
- Intravital microscopy has shown potential in risk stratification and outcome prediction.
- Newer diagnostic tools offer promising avenues for direct or indirect microcirculation evaluation.
Conclusions:
- Optimizing organ perfusion and oxygenation through microcirculation surveillance can lead to individualized therapy.
- Advanced diagnostic methods are essential for accurate assessment and management of microcirculatory disorders in ICUs.
- Further research into novel diagnostic devices is warranted to improve patient care and outcomes.
