低位腹主动脉间歇性阻断技术的临床应用

Clinical use of intermittent block of lower abdominal aorta

目的 回顾低位腹主动脉间歇性阻断技术在骶骨肿瘤切除、骨盆严重损伤合并其它器官裂伤修复术中的临床应用效果。方法 术中应用消毒皮管加粗鞋带套结法间歇性阻断腹主动脉 9例。结果 术中失血量得到有效控制 ,输血量减少 ,手术野清晰 ,缩短了术中止血时间 ,且生命体征较稳定。术后观察及长期随访未发现因血管阻断而出现的各种并发症。结论 低位腹主动脉间歇性阻断技术 ,操作简便 ,血流阻断范围广 ,技术可靠 ,能有效减少失血量。

Objective To review the clinical effect of the intermittent block of lower abdominal aorta in resection for sacral tumor and treatment of serious pelvis injury complicated with ruptured visceras. Methods 9 patients lower abdominal aortas were intermittent strapped and blocked by sterilized rubber tube and shoelace during operations. Results The technique could evidently decrease bleeding and blood transfusion during operations. The field of vision in operations was clear,the stanching bleeding time was shortened and the life sign was stable. The patients were followed up postoperatively for a long time and no complications occured because of the block. Conclusion The technique of the intermittent block of lower abdominal aorta is easily handled.The range of blood blocked is wide . The technique is reliable,and can reduce hemorrhage effectively.
