What is the first fluid choice for IV resuscitation after acute blood loss?

• A. Colloids (e.g., albumin)
• B. Blood
• C. Crystalloids (saline)
• D. Dextrose

Answer: (C)

Initial fluid resuscitation after acute blood loss focuses on rapidly restoring intravascular volume with isotonic crystalloids. Solutions like normal saline or lactated Ringer’s expand the circulating volume effectively, are quick to administer, and remain safely within the extracellular space to improve preload and perfusion without needing crossmatching. If bleeding persists or oxygen delivery remains inadequate, blood transfusion is indicated to restore hemoglobin and oxygen carrying capacity. Colloids aren’t the first choice due to cost and potential risks, and dextrose solutions don’t provide meaningful intravascular volume expansion for resuscitation.
