Which of the following is a colloid of choice for Tactical Combat Casualty Care?

Hextend is a colloid solution that is specifically designed to expand intravascular volume and is particularly beneficial in the context of Tactical Combat Casualty Care (TCCC). It contains hydroxyethyl starch, which acts to maintain osmotic pressure and draw fluid into the vascular space, helping to treat or prevent hypovolemic shock in trauma patients. The additional benefit of Hextend is its relatively low volume requirement to achieve effective volume expansion compared to crystalloids, making it advantageous in field situations where fluid resuscitation needs to be efficient and rapid.

This characteristic, along with its longer-lasting effects compared to other fluids, allows TCCC providers to stabilize patients while transport or surgical intervention is arranged. Its use helps maintain hemodynamic stability and can be crucial in tactical scenarios where resources may be limited, and rapid decision-making is essential.
