目的 探讨大号腕部固定支具应用于经肱动脉冠状动脉介入术后上肢制动的效果。方法 选取2012-2016年经肱动脉 冠状动脉介入术的50例病人,分为对照组和实验组各25例， 对照组介入术后, 拔出鞘管，压迫穿刺处止血，然后用 绷带环形加压包扎穿刺点，肘关节制动8小时，8小时后拆除绷带。实验组同样方法加压包扎穿刺点后，将患者穿刺 侧上肢以肘关节为中心置入制动支具内，根据患者臂围调节支具的松紧度，8小时后拆除支具和绷带。结果 两组的 舒适度、焦虑程度有明显的统计学差异(P<0.05)。结论 大号腕部固定支具应用于经肱动脉冠状动脉介入术后的上 肢制动，提高了患者的舒适度，减轻了患者的焦虑程度，提高了患者的遵医行为，减少了穿刺处出血血肿的并发 症。

Objective To investigate the effect of large-scale wrist fixation brace on brachial artery brachial artery intervention. Methods Fifty patients with brachial artery coronary intervention were divided into control group and experimental group. Twenty-five patients were divided into control group and experimental group. In the control group, the sheath was pulled out and the puncture was stopped. Then, Pressure bandage puncture point, elbow brake 8 hours, 8 hours after the removal of the bandage. The same method of the experimental group after compression banding puncture point, the patient's puncture side of the upper limb to the elbow as the center into the brake brace, according to the patient's arm to adjust the tightness of the brace, 8 hours after the removal of braces and bandages. Results There were significant differences in the degree of comfort and anxiety between the two groups (P<0.05). Conclusion The large wrist fixation is applied to the brachial brachial artery brachial arterial intervention, which improves the patient's comfort, reduces the anxiety of the patients, improves the patient's compliance behavior and reduces the bleeding Hematoma complications.
