Choosing the appropriate crystalloid solution depends on the patient's condition and clinical needs:
Normal Saline: Often used for general fluid resuscitation, dehydration, and metabolic alkalosis. Lactated Ringer's: Preferred in surgical and trauma patients due to its electrolyte composition that closely mimics plasma. Dextrose in Water: Suitable for providing free water for renal excretion of solutes, but not ideal for volume resuscitation as it quickly diffuses out of the vascular space. Half-normal saline: Used for patients with hypernatremia or as a maintenance fluid.
