Colloid and crystaloid

Pulmonary edema is among the least frequently diagnosed criteria for severe pre-eclampsia. A higher incidence of pulmonary edema was noted in older patients, multigravidas, and patients with underlying chronic hypertension that developed prior to delivery. The development of pulmonary edema was also associated with the administration of excess colloid or crystaloid infusion. Two hundreds and thirty millions people occupying Indonesia as tropical and coastal country gave rise the problem of highly maternal mortality rate of 225/100,000 deliveries where pre-eclampsia and eclampsia as most possible cause...

The treatment with infusion fluids in perioperative period is a basic therapeutic method. Depending on clinical situation, the doctor has various fluids available, both blood-replacing, and blood-derived. The number of crystaloid and colloidal fluids used has been systematically growing in two last decades. Ever more importance, beside the 0.9% NaCl solution and Ringer's solution used, is gaining 7.5% NaCl solution and hydroxyethyl starch solutions. The production of hydroxyethyl starch solutions in Poland has created an alternative to the use of dextran and gelatin solutions...

Substitutes for whole blood include blood fractions such as plasma, serum albumin and other fluids of various kinds which are not derived from blood but are used as plasma volume expanders; these, include the usual crystaloid intravenous solutions. Since in comparison to blood far more of these later solutions are given intravenously, a thorough knowledge of plasma volume expanders is essential. The first use of such expanders in human patients was by Hogan in 1915. He used colloidal gelatin and noted an improvement in blood pressure in shock...

Reported are three maternal deaths in four patients who presented with a similar syndrome following a normal antepartum course and normal labor and delivery managed by regional or local anesthesia and midline or proctoepisiotomy. Beginning about the second postpartum day, the patients developed unilateral perineal edema and induration which progressed to generalized vulvar, vaginal, perineal, and gluteal edema and induration. These patients developed marked leukocytosis, fever, and ultimately vascular collapse; three of them died...
