There are several different types of IV fluids and trained medics determine which is most suitable in any given case. The precise IV solution will vary depending on your medical condition and needs. Doctors take into account body size and age to ensure the right amount of IV fluid is given.
Normal saline is one of the most common IV fluids and nurses administer it for most hydration needs. For example, it can be a lifesaver after a haemorrhage, vomiting, diarrhea, metabolic acidosis, or shock.
IV fluids can also be nutrient solutions containing dextrose, glucose and levulose and water. Electrolyte solutions contain substances that are used to replace fluid and electrolytes in patients with continuing losses.
Lactated ringers is the IV fluid of choice for burn and trauma patients. It’s also used for acute blood loss, electrolyte imbalance and metabolic acidosis.
