手指大部分离断伤非显微外科治疗效果观察

目的探讨在无显微外科条件下手指大部分离断伤的治疗方法。方法回顾了1996年～2001年经筛选的34例伴有双侧指动脉损伤的手指大部分离断伤患者的临床资料。急诊手术时采用了避免医源性扩创、最大限度保护伤指远近端连系部的原则，术后采用热疗、山莨菪碱等措施挖掘连系部微血管的供血潜力，复苏伤指远端的休克状态。结果所有伤指在急诊手术后甲床毛细血管充盈试验由0分上升为1分，伤指远端组织获得复苏且成活，28例伤口愈合良好，6例伤口边缘干性坏死，切除坏死部分后瘢痕愈合。随访到31例，骨折愈合后均行指神经、肌腱二期修复术，保存了手指长度，恢复了基本功能。结论采用非显微外科方法并配合其他改善微血管供血、纠正休克状态等措施，治疗手指大部分离断伤是可行的，尤其适合在无显微外科条件的基层医疗单位采用。

CLINICAL EFFICACY OF NON-MICROSURGICAL TREATMENT FOR MOSTLY-ISOLATED FINGER WITH ITS BILATERAL ARTERIA INJURY

Objective To explore a method to treat the mostly isolated finger with its bilateral arteria injury without microsurgery. Methods To avoid exacerbating iatrogenically the wound, the methods of therapy mainly included the following procedures: debriding carefully, suturing the cutis and subcutaneous layer to fix internally the fracture without Kirschner wire, and not suturing the broken finger nerve or the broken tendon which had rebound. It was used in the emergency operation. After operation, heat therapy and Anisodamine were used to dilate capillary and micrangium of the unbroken soft tissue of the wounded finger, which was anatomically the only base of blood supply of pars of the wounded finger. Results In the 34 cases, main blood supply of the wounded finger was restored. The wound healed well in 28 cases. In 6 cases of necrosis in the edge of the wound, the necrosis were excised and the cicatricial healing was achieved. In 31 patients followed up, after the fracture had healed, the nerve and tendon were repaired. Conclusion The methods above should be available for the mostly isolated finger, especially in a hospital without microsurgery.
