Abstract:
The translation of preclinical results into successful clinical therapies remains a challenge in sepsis research. One reason for this lack of translation might be the discrepancy between preclinical models and the clinical reality: nonresuscitated young healthy rodents in contrast to elderly comorbid patients in an intensive care unit. We introduce the mouse intensive care unit (MICU) as a concept to address the lack of resuscitation in preclinical studies as one of the limiting issues in translational research. The MICU reflects standard procedures of the clinical intensive care unit: fluid resuscitation, lung-protective mechanical ventilation, and hemodynamic monitoring and management, all tailored to organ- and function-specific targets. Thus, the MICU gives an experimental animal the intermediate possibility of recovery and survival due to "patient" management, which is not reflected in less complex experimental scenarios, which either result in acute survival or death.
Insights
Translational research in sepsis faces challenges due to unrealistic preclinical models. The mouse intensive care unit (MICU) simulates clinical intensive care, improving sepsis model translatability.
Area of Science:
- Critical care medicine
- Translational research
- Sepsis research
Background:
- Translating preclinical sepsis findings to clinical practice is difficult.
- Preclinical models often lack the complexity of human sepsis patients, particularly regarding resuscitation and comorbidities.
- Existing models do not adequately reflect intensive care unit (ICU) management.
Purpose of the Study:
- To introduce the mouse intensive care unit (MICU) as a novel preclinical model for sepsis research.
- To address the limitations of current preclinical sepsis models, specifically the lack of resuscitation.
- To enhance the translational validity of sepsis research by incorporating clinical ICU procedures.
Main Methods:
- Development of a mouse intensive care unit (MICU) that mimics clinical ICU settings.
- Implementation of key ICU procedures: fluid resuscitation, lung-protective mechanical ventilation, and hemodynamic monitoring.
- Tailoring interventions to organ- and function-specific targets in experimental animals.
Main Results:
- The MICU provides a platform for "patient" management, allowing experimental animals a possibility of recovery.
- This approach bridges the gap between simplified preclinical models and complex clinical realities.
- The MICU facilitates the study of sepsis under conditions more relevant to human ICU patients.
Conclusions:
- The MICU represents a significant advancement in preclinical sepsis research methodology.
- This model enhances the translatability of sepsis research by incorporating critical care interventions.
- The MICU offers a more realistic platform for developing effective sepsis therapies.
