The use of colloids and crystalloids for resuscitation of bleeding patients has previously remained controversial with no definitive answer for the best course of action [ 1, 2, 3, 4 ]. Saline, which is an aqueous solution of sodium chloride, is a crystalloid. The CRISTAL trial did show a reduced 90-day mortality in patients with hypovolemic shock treated with colloids.1 However, according to a recent Cochrane review, there is no evidence that colloid resuscitation instead of crystalloids reduces mortality following trauma, burns, or surgery.2 One trial suggested that hydroxyethyl starch may actually increase 90-day incidence of death and renal replacement therapy compared to lactate ringers in patients with severe sepsis.3 Several studies have posited that albumin may exert a benefit to the microcirculation in certain conditions such as cirrhosis and spontaneous bacterial peritonitis that could in theory be beneficial in the perioperative period. The key difference between crystalloids and colloids is that the colloids contain much larger molecules than that of crystalloids. crystalloids and colloids please comment for any changes..

This estimate was heavily influenced by the results of the SAFE trial, which contributed 91% of the information (based on the weights in the meta-analysis). that the colloids may have a detrimental effect on renal performance. In general, it may be stated that colloids have a particle size of 1 to 1000 nm (nanometer); few colloids have somewhat smaller size. The particles distribute within the colloidal medium do not settle down if it is left still. Patients assigned to crystalloids received a median (IQR) amount of 3905mL (2880-5288) of crystalloid. 65 This "context sensitivity," with less translocation at lower venous pressures, may explain . Trauma, burns or surgery can cause people to lose large amounts of blood. This definition puts no limitation as to the substances that can behave like a colloid. 2.
