Literature review reveals severe microcirculatory shutdown and endothelial failure in septic shock, highlighting tiny vessel preservation as vital for patient survival.

Key Points

To review the pathological mechanisms responsible for microcirculatory impairment during sepsis and endotoxic shock, emphasizing microvascular protection as a key therapeutic target.
Synthesized foundational and modern medical literature regarding vascular responses, cellular dynamics, and endothelial barrier functions during shock.
Extracted consensus findings from basic science investigations, clinical reports, and expert forum reviews on microvascular failure.
Microvascular perfusion decreases precipitously early in sepsis due to reduced systemic perfusion pressure, localized arteriolar constriction, and pathological arteriovenous shunting that bypasses nutritional capillary exchange.
Capillary obstruction worsens as red and white blood cells lose deformability, cellular debris plugs microvessels, and neurohumoral autoregulation fails across disparate tissue beds.
Endothelial dysfunction increases transcapillary fluid extravasation, activates leukocytes, and promotes prolonged capillary stasis, creating an acidic, hypoxic niche that enables tissue destruction.
