## **Core Concept**
The target blood pressure for resuscitation in trauma patients, particularly those without head injury, is guided by principles of trauma care and resuscitation. The goal is to ensure adequate perfusion of vital organs without exacerbating bleeding.

## **Why the Correct Answer is Right**
The correct approach for trauma patients without head injury involves maintaining a blood pressure that ensures adequate organ perfusion. The concept of permissive hypotension has been increasingly adopted in trauma care. This approach involves allowing a slightly lower blood pressure during resuscitation to avoid dislodging clots and to minimize ongoing blood loss. A commonly recommended target systolic blood pressure (SBP) is around 90 mmHg, as this balances the need for adequate perfusion with the risk of exacerbating hemorrhage.

## **Why Each Wrong Option is Incorrect**
- **Option A:** A target blood pressure that is too high may dislodge clots and worsen bleeding, while a too low pressure may result in inadequate organ perfusion. Without specifying the exact values, we can infer that very high or very low targets are not ideal.
- **Option B:** Similarly, another non-optimal target that does not align with current trauma resuscitation guidelines.
- **Option D:** This option likely represents a blood pressure target that might be considered too low or too high for a trauma patient without head injury, given the context of current trauma care principles.

## **Clinical Pearl / High-Yield Fact**
A key concept in trauma resuscitation is the idea of permissive hypotension, particularly in patients without head injuries. For these patients, aiming for a systolic blood pressure of approximately **90 mmHg** during initial resuscitation can help balance the need for adequate organ perfusion with the risk of worsening bleeding. This approach does not apply to patients with head injuries, as they require higher blood pressures to ensure adequate cerebral perfusion.

## **Correct Answer:** . 90 mmHg
