Renal causes include overuse of diuretics, or trauma or disease of the kidney. … Visa mer WebbCrystalloid solutions for intravascular volume replenishment are typically isotonic (eg, 0.9% saline or Ringer's lactate). Water freely travels outside the vasculature, so as little as 10% of isotonic fluid remains in the intravascular space. With hypotonic fluid (eg, 0.45% saline), even less remains in the vasculature, and, thus, this fluid is not used for resuscitation.
