目的比较普鲁卡因贯续支气管动脉栓塞术与单纯支气管动脉栓塞术治疗老年性患者大咯血的临床疗效。方法63例老年性大咯血患者随机接受普鲁卡因贯续支气管动脉栓塞术与单纯支气管动脉栓塞术治疗，普鲁卡因贯续支气管动脉栓塞术27例，单纯支气管动脉栓塞术治36例。比较两组的止血率、死亡率、并发症，复发率和治疗费用。结果普鲁卡因贯续支气管动脉栓塞术治疗组中止血26例（96.30%），其中单纯应用普鲁卡因未行介入治疗15例(55.56%)，支气管动脉栓塞组止血34例(94.44%)，两组止血率、死亡率、复发率比较差异无显著性(>0.05)。普鲁卡因联合支气管动脉栓塞组治疗费用两组比较具有显著性差异(0.05) . However, the cost of treatment was significantly dif erence ( <0.05). Conclusion Procaine continued with bronchial artery embolization was a massive hemoptysis clinical use prefer ed drug program, and the cost of treatment significantly decreased.
