oa Southern African Journal of Anaesthesia and Analgesia - Relative hypovolaemia : review



Extracted from text ... REVIEW Southern African Journal of Anaesthesia & Analgesia - May 2005 68 Relative Hypovolaemia Normovolaemia with ECF and ICF depletion Plasma volume is frequently well maintained by oncotic forces even in the presence of significant extracellular and intracellular fluid losses. Intracellular fluid depletion develops relatively slowly and can lead to significant total body fluid depletion. Although not primarily hypovolaemia, induction of anaesthesia can markedly inhibit the protective reflexes that maintain ECF at the expense of the ICF and lead to rapid development of hypovolaemia without any apparent volume loss. There are a number of situations in which such intracellular ..
