Detailed explanation-1: -Isotonic IV fluids include normal saline, 5% dextrose solutions dissolved in water, and Lactated Ringer’s solutions. These are used for dehydration caused by electrolyte imbalances as well as fluid loss from diarrhea and vomiting.
Detailed explanation-2: -For severe dehydration, start IV fluids immediately. If the patient can drink, give ORS by mouth while the IV drip is set up. Ringer’s lactate IV fluid is preferred. If not available, use normal saline or dextrose solution.
Detailed explanation-3: -The simplest approach is to replace dehydration losses with 0.9% saline. This ensures that the administered fluid remains in the extracellular (intravascular) compartment, where it will do the most good to support blood pressure and peripheral perfusion.
Detailed explanation-4: -Isotonic IV Fluids Isotonic IV fluids are used to increase fluid volume due to blood loss, surgery, or dehydration . There are many different types of common isotonic fluids, such as: 1. Normal Saline (0.9% NaCl, NS) 2. 5% Dextrose in Water (D5W) 3.
Detailed explanation-5: -Isotonic solutions are used: to increase the EXTRACELLULAR fluid volume due to blood loss, surgery, dehydration, fluid loss that has been loss extracellularly.
