经桡动脉冠脉造影术后绷带拆除时间的比较

目的 研究经桡动脉行冠脉造影术后桡动脉绷带拆除的时间。 方法 选取因冠心病入院行冠脉造影术但未行支架植入的患者300例，根据术后加压包扎的时间分为3组:4 h组100例，6 h组100例，8 h组100例，观察3组患者桡动脉绷带拆除后桡动脉穿刺点出血情况、穿刺侧前臂血肿发生情况、肢体坏死、局部皮肤水疱形成、患者不适感、术前及术后血常规、凝血酶原时间（PT）、活化部分凝血酶原时间（APTT）变化等并发症的发生率。 结果 ①术前3组间血常规、PT、APTT均无显著差异。②术后4 h、6 h和8 h穿刺点出血发生率无显著性差异。三组间穿刺侧前臂血肿发生、肢体坏死发生、局部皮肤水疱形成无显著性差异 ，且4 h组患者不适感明显低于6 h及8 h组。 结论 冠脉造影术后4 h拆除绷带，穿刺点无明显出血发生，患者不适感明显减轻，安全可行。

The research of time of bandage removal after coronary angiography through the radial artery

AIM To study the time of bandage removal after coronary angiography through the radial artery. METHODS 300 patients were selected with coronary heart disease who underwent coronary angiography but without stent implantation were divided into three groups according to postoperative pressurized bandaging time: a 4 h group (100 patients), a 6 h group (100 patients), a 8 h group (100 patients). The present investigation observed incidence of complications, including puncture point bleeding, forearm hematoma, limb necrosis, skin blister formation, discomfort of patients, routine blood work, prothrombin time (PT) and activated partial thromboplastin time (APTT) changes. RESULTS There were no significant differences in routine blood, prothrombin times, and activated partial thromboplastin times between the three groups before operation. There were no significant differences in incidence of bleeding at 4 h, 6 h and 8 h punctures after operation. There were no significant differences in puncture point bleeding, forearm hematoma, limb necrosis or local skin blister formation between the three groups. The discomfort in group 4 h was significantly lower than that in the 6 h and 8 h groups. CONCLUSION Based on the results of this study, bandage removal at 4 h after coronary angiography through the radial artery was safe with no obvious bleeding in the puncture point.
