冠脉造影术后拔除动脉鞘管的时间与血肿关系观察

目的：观察冠脉造影术（CAG）毕动脉鞘管拔除时间与血肿发生率的关系。方法：将403例CAG患者随机分为实验组和对照组，实验组在CAG后30-40min拔除动脉鞘管，对照组在术后立即拔除动脉鞘管；拔管后均以股动脉压迫止血器止血：观察两组患者CAG后血肿发生率。结果：实验组血肿的发生率为3．81％，对照组为8．81％，实验组较对照组显著降低（P〈0．05）。结论：CAG后30～40min拔除动脉鞘管较术后立即拔除动脉鞘管可明显降低血肿的发生率。

Effect of different time of arterial sheaths extubation on incidence of hematoma in patients with coronary angiography

Objective：To study the influence of different time of arterial sheaths extubation on the incidence of hematoma in the patients with coronary angiography（CAG）. Methods：403 cases were randomly divided into experimental group and control group. The arterial sheaths were extubated 30-40 min after CAG in the experimental group, while those were extracted instantly after CAG in the control group. After that,femoral artery compression apparatus were used to prevent bleeding in both groups. Finally, the incidence of hematoma in each group was observed. Results：The incidence of hematoma was 3.81% in the experimental group and 8.81% in the control group.The incidence of hematoma in the experimental group was significantly lower than that in the control group （P〈0.05）. Conclusion： Extubating the arterial sheaths 30-40 min after CAG can lower the incidence of hematoma compared with immediate extubation after CAG.
