Crystalloid osmotic pressure

WebThe value of intravenous crystalloid administration in preventing spinal-induced hypotension in the parturient has recently been questioned. Also, the association between increasing crystalloid volume and decreasing postpartum colloid osmotic pressure (COP) raises concern regarding the risk of maternal and fetal pulmonary edema. WebMar 12, 2014 · An iso-osmotic crystalloid fluid (that is, equalling the physiological plasma osmolality of 288 ± 5 mosmol/kg) equally distributes to the intravascular and the interstitial space [ 9 ], because the peripheral endothelial cells allow a more or less unrestricted exchange of water and electrolytes.

WebDec 20, 2024 · Crystalloid fluid administered into the peritoneal cavity increases the intraperitoneal pressure, which is also transmitted to the peritoneal interstitial tissue and will thereby lower the hydrostatic filtration gradient to some extent. WebMay 8, 2024 · Colloid solutions have been developed and used over the past 70 years as expanders of the intravascular space, based on an understanding of Starling's law. Increasing osmotic pressure with colloidal products has remained an attractive theoretical premise for volume resuscitation.

WebSimilar to isotonic and hypotonic crystalloids, the intravascular volume expansion effect of hypertonic saline is transient (<30 minutes) because of the redistribution of electrolytes (i.e., sodium and its associated anions) throughout the extravascular space. 6 The ensuing osmotic diuresis also facilitates excess sodium excretion. To prolong ...
