腹主动脉阻断术的临床应用研究

Clinical research on temporary blockage of abdominal aorta

目的 探讨腹主动脉阻断技术的临床适用性。 方法 通过 2 0例腹主动脉阻断术的临床应用 ,对术中出血量进行评估 ,观察血压、心率及血氧饱和度 (SaO2 )变化情况 ,并行术后随访。 结果 应用腹主动脉阻断术可使术中患者减少出血量 5 0 0～ 15 0 0ml,术中生命体征平稳 ,术后无并发症发生。 结论 腹主动脉阻断术是一种预防骨盆及骶尾部手术中出血。

Objective To study the clinical application of temporary blockage of abdominal aorta. Methods Twenty patients with sacral tumor or pelvic disease received temporary blockage of abdominal aorta. We monitored the changes of blood pressure, heart rate and SaO 2 during the operation and followed up all the cases. Results The mean volume of bleeding was decreased from 500 ml to 1 500 ml. Statistical data indicated that there was no significant difference between pre blockage and post blockage ( P >0.05). No complications were found during follow up after the operations. Conclusions Temporary blockage of abdominal aorta is effective in controlling the bleeding in the operations of sacralis and pelves. It is safe and reliable in clinical application without complications.
