The choice between colloids and crystalloids is a longstanding debate in medical circles. Colloids, such as albumin and hydroxyethyl starch, are often considered in situations where rapid blood volume expansion is needed. They remain in the circulation longer than crystalloids, which can be beneficial in preventing hypovolemia. However, crystalloids are much cheaper and have a lower risk of adverse reactions. The decision usually depends on the clinical scenario and the patient's specific needs.
