A patient with long bone fractures above and below the diaphragm is at increased risk for associated internal torso injuries. Severe crush injuries cause the release of __________________________ from the muscle, which can precipitate in the renal tubules and result in renal failure. ____________________________, an uncommon but highly lethal complication of long-bone fractures, can lead to pulmonary failure and impaired cerebral function Severe crush injuries cause the release of myoglobin from the muscle, which can precipitate in the renal tubules and result in renal failure. Fat embolism, an uncommon but highly lethal complication of long-bone fractures, can lead to pulmonary failure and impaired cerebral function Appropriate __________________________ fractures can significantly decrease bleeding by reducing motion and enhancing the tamponade effect of the muscle and fascia. Appropriate splinting of fractures can significantly decrease bleeding by reducing motion and enhancing the tamponade effect of the muscle and fascia. Assess injured extremities for _________________________________________________________________________________________________ Assess injured extremities for external bleeding, loss of previously palpable pulse, and changes in pulse quality, Doppler tone, and ankle/brachial index. The ankle/brachial Index is determined by taking the systolic blood pressure value at the ankle of the injured leg and dividing it by the systolic blood pressure of the uninsured arm.
