Capillary leak syndrome is a pathological condition marked by the excessive escape of plasma and proteins from capillaries into surrounding tissues, resulting in significant edema and potential hypovolemia. Not to be confused with hypovolemic shock, where fluid loss occurs due to external bleeding, this syndrome primarily involves fluid redistribution within the vascular and interstitial compartments. It is often associated with critical conditions such as sepsis, severe allergic reactions, and systemic inflammatory response syndrome (SIRS), complicating patient management in emergency medical situations, including those governed by NIMS protocols.
