Zusammenfassung
Hintergrund
Schwerbrandverletzte (mehr als 20% verbrannter Körperoberfläche bei Erwachsenen) weisen in der ersten Phase (8–48 h) einen durch das massive Kapillarleck bedingten Verbrennungsschock auf, der einer Infusionstherapie bedarf, um die Hämodynamik wieder herzustellen. Bis in die 80er Jahre stellte eine unzureichende Flüssigkeitstherapie (Unterinfusion) die Haupttodesursache von Verbrennungspatienten dar. Seither ist die übermäßige Flüssigkeitstherapie (Überinfusion) zu einer beachtenswerten Quelle von Komplikationen geworden: abdominales Kompartmentsyndrom, Entlastungsschnitte (Escharotomie), Verschlechterung des Gasaustauschs, Verlängerung der künstlichen Beatmung und des Spitalaufenthalts. Die Überinfusion hat Ende der 90er Jahre begonnen, wo innerhalb der ersten 24 h Flüssigkeitsmengen zugeführt wurden, die weit über den 4 ml/kg/% BSA („burn surface area“) der Parkland-Formel lagen.
Ziel
Dieser Beitrag analysiert die Faktoren, welche zu einer Überinfusion führen können und zeigt Möglichkeiten, dem durch eine strikte Kontrolle der präklinischen Infusionstherapie sowie durch eine permissive Hypovolämie vorzubeugen.
Abstract
Background
Major burns are characterized by an initial capillary leak, which requires fluid resuscitation for hemodynamic stabilization. While under resuscitation was the major cause of death until the 1980s, over resuscitation has become an important source of complications, including abdominal compartment syndrome, escharosis, impaired gas exchange with prolonged mechanical ventilation and hospital stay. Fluid over infusion started in the 1990s with an increasing proportion of the fluid delivered within the first 24 h being well above the 4 ml/kg/% burn surface area (BSA) according to the Parkland formula. The first alerts were published in the form of case reports of increased mortality due to abdominal compartment syndrome and respiratory failure.
Objective
This paper analyses the causes of this fluid over infusion and the ways to prevent it, which include rationing prehospital fluid delivery, avoiding early administration of colloids and prevention by permissive hypovolemia.
