[Function of the respiratory and circulatory systems in patients with mandibular fractures]

In 178 patients treated for the lower jaw fractures the respiration and gas exchange were studied. Respiratory insufficiency was caused by obstructive events due to bone fragments and maxillofacial soft tissues dislocation with arterial blood levels of oxygen decreased and hemoglobin oxygen saturation lowered. Traumatic stress resulted in hyperdynamic circulatory response correlating with the severity of lesion.
