Abstract

OBJECTIVE: Microcirculatory perfusion disturbances following hemorrhagic shock and fluid resuscitation contribute to multiple organ dysfunction and mortality. Standard fluid resuscitation is insufficient to restore microcirculatory perfusion, however, additional therapies are lacking. We conducted a systematic search to provide an overview of potential non-fluid based therapeutic interventions to restore microcirculatory perfusion following hemorrhagic shock.

METHODS: A structured search of PubMed, EMBASE and Cochrane Library was performed in March 2020. Animal studies needed to report at least one parameter of microcirculatory flow (perfusion, red blood cell velocity, functional capillary density).

RESULTS: The search identified 1269 records of which 48 fulfilled all eligibility criteria. In total, 62 drugs were tested of which 29 were able to restore microcirculatory perfusion. Particularly complement inhibitors (75% of drugs tested successfully restored blood flow), endothelial barrier modulators (100% successful), antioxidants (66% successful), drugs targeting cell metabolism (83% successful) and sex hormones (75% successful) restored microcirculatory perfusion. Other drugs consisted of attenuation of inflammation (100% not successful), vasoactive agents (68% not successful) and steroid hormones (75% not successful).

CONCLUSION: Improving mitochondrial function, inhibition of complement inhibition and reducing microvascular leakage via restoration of endothelial barrier function seems beneficial to restore microcirculatory perfusion following hemorrhagic shock and fluid resuscitation.
