Analysis of early treatment of multiple injuries combined with severe pelvic fracture.

PURPOSE

To summarize and analyze the early treatment of multiple injuries combined with severe pelvic fractures, especially focus on the hemostasis methods for severe pelvic fractures, so as to improve the successful rate of rescue for the fatal hemorrhagic shock caused by pelvic fractures.

METHODS

A retrospective analysis was conducted in 68 cases of multiple trauma combined with severe pelvic fractures in recent 10 years (from Jan. 2006 to Dec. 2015). There were 57 males and 11 females. Their age ranged from 19 to 75 years, averaging 42 years. Causes of injury included traffic accidents in 34 cases (2 cases of truck rolling), high falling injuries in 17 cases, crashing injuries in 15 cases, steel cable wound in 1 case, and seat belt traction injury in 1 case. There were 31 cases of head injury, 11 cases of chest injury, 56 cases of abdominal and pelvic injuries, and 37 cases of spinal and limb injuries. Therapeutic methods included early anti-shock measures, surgical hemostasis based on internal iliac artery devasculization for pelvic hemorrhage, and early treatment for combined organ damage and complications included embolization and repair of the liver, spleen and kidney, splenectomy, nephrectomy, intestinal resection, colostomy, bladder ostomy, and urethral repair, etc. Patients in this series received blood transfusion volume of 1200-10,000 mL, with an average volume of 2850 mL. Postoperative follow-up ranged from 6 months to 1.5 years.

RESULTS

The average score of ISS in this series was 38.6 points. 49 cases were successfully treated and the total survival rate was 72.1%. Totally 19 patients died (average ISS score 42.4), including 6 cases of hemorrhagic shock, 8 cases of brain injury, 1 case of cardiac injury, 2 cases of pulmonary infection, 1 case of pulmonary embolism, and 1 case of multiple organ failure. Postoperative complications included 1 case of urethral stricture (after secondary repair), 1 case of sexual dysfunction (combined with urethral rupture), 1 case of lower limb amputation (femoral artery thrombosis), and 18 cases of consumptive coagulopathy.

CONCLUSION

The early treatment of multiple injuries combined with severe pelvic fractures should focus on pelvic hemostasis. Massive bleeding-induced hemorrhagic shock is one of the main causes of poor prognosis. The technique of internal iliac artery devasculization including ligation and embolization can be used as an effective measure to stop or reduce bleeding. Consumptive coagulopathy is difficult to deal with, which should be detected and treated as soon as possible after surgical measures have been performed. The effect of using recombinant factor VII in treating consumptive coagulopathy is satisfactory.
