Decreased pulses is a critical finding associated with vascular injuries in musculoskeletal trauma because it indicates compromised blood flow to the affected extremity. When a vascular injury occurs, it can lead to disruption of the blood supply, resulting in diminished or absent pulses distal to the injury site. This finding can signal significant trauma, necessitating immediate assessment and potential surgical intervention to restore blood flow and prevent further complications, such as limb ischemia.

In vascular injuries, maintaining adequate perfusion is vital for the health of the tissues, so healthcare providers closely monitor pulse status during the evaluation of musculoskeletal traumas. A notable absence of pulses may also indicate a complete injury to an artery, which demands urgent attention to prevent tissue death.

While other findings such as increased heart rate, swelling, and fever can be present in trauma cases, they are not specific indicators of vascular injury. Increased heart rate may occur due to pain, anxiety, or shock, swelling can arise from soft tissue injury or inflammation, and fever could be an indication of infection rather than vascular compromise. Thus, the presence of decreased pulses is a key diagnostic criterion that highlights the significance of potential vascular injuries in traumatic scenarios.
