Fluid resuscitation is a medical intervention used to treat patients who are experiencing severe dehydration or hypovolemia (low blood volume). This treatment involves administering fluids intravenously to restore the patient's fluid and electrolyte balance, improve circulation, and support vital organ function. Fluid resuscitation is commonly used in emergency situations such as trauma, sepsis, or severe dehydration, and is essential for stabilizing patients and preventing further complications. Researchers in this area study the most effective types of fluids, optimal dosages, timing of administration, and potential complications associated with fluid resuscitation. The goal of this research is to improve outcomes for patients who require fluid resuscitation and to develop evidence-based guidelines for clinical practice.
