经桡动脉径路冠状动脉介入术后气囊压迫器不同压迫时间的止血效果比较

目的 观察桡动脉压迫器(TR-Band止血气囊)在桡动脉径路介入术后的止血效果并探讨最适止血时间.方法 将266例经桡动脉行冠状动脉造影术并用TR-Band止血气囊压迫止血的患者,按压迫时间随机分为A、B、C3组.A组90例压迫8h,B组87例压迫10h,C组89例压迫12h,比较3组出血情况、血氧饱和度的变化情况和手部肿胀情况.结果 A、B、C3组出血率分别为16.7％、3.4％、9.0％,3组比较差异显著；术后手部肿胀发生率A、B、C3组分别为27.8％、12.6％、21.3％,3组比较差异显著；3组术后末梢血氧饱和度比较差异无统计学意义.结论 桡动脉径路冠状动脉介入术后应用气囊压迫器止血效果较好,以压迫10h效果最好,且不良反应少.

Comparison of the hemostatic time of the radial hemostatic compression device after transradial coronary intervention

Objective To investigate the hemostatic effect of the radial hemostatic compression device(TR Band hemostatic gasbag)after transradial coronary intervention and discuss the optimal hemostasis time.Methods 266 patients who received transradial coronary angiography and used TR Band hemostatic gasbag for hemostasis were divided into group A,B and C,according to the compression time,the compression time in group A (90 cases)was 8 h,10 h in group B (87cases),12 h in group C (89 cases).The condition of bleeding,changes in blood oxygen saturation,and hand swelling in each group were compared.Results The bleeding rates of group A,B and C were respectively 16.7％,3.4％ and 9.0％,the difference was statistically significant.The incidence of hand swelling after operation in group A,B and C were respectively 27.8％,12.6％ and 21.3％,the difference was statistically significant.No significant difference was seen in blood oxygen saturation between three groups.Conclusions Application of radial hemostatic compression device after transradial coronary intervention proved good hemostasis effect,compression time for 10 h has the best effect and less adverse effect.
