近年来,随着人们对休克发病机理的认识加深,多巴胺在抗休克治疗中应用越来越广。多巴胺有直接兴奋β受体,增强心肌和心排出量,改善重要脏器循环的作用,比单纯使用去甲肾上腺素的作用效果好。但如果使用不当,也可发生一些副作用。近半年,我院在抢救休克病人时,曾发生4例患者注射部位局限性组织坏死。现将2例典型病例详述如下。例1,男,50岁,因胆道休克,急性胆囊炎、胆石症入院。在抗休克过程中,我们用多巴胺80mg加入5％葡萄糖500ml中,经左臂桡静脉输液。8小时后,患者穿刺部位的近心端,包括腕背与桡侧沿着头静脉的走向周围出现了大片红斑,红斑边
In recent years, with the deepening of people’s understanding of the pathogenesis of shock, dopamine is more and more widely used in anti-shock therapy. Dopamine has a direct excitement β receptor, enhance myocardial and cardiac output, improve the role of important organs circulation, than the simple use of norepinephrine effect is good. However, if used improperly, some side effects can also occur. Nearly six months, our hospital in the rescue of patients with shock, there have been four cases of patients with localized tissue necrosis at the injection site. Now 2 cases of typical cases are as follows. Example 1, male, 50 years old, due to biliary shock, acute cholecystitis, cholelithiasis admitted. In the anti-shock process, we use dopamine 80mg added to 500ml of 5% glucose, the left arm radial vein infusion. After 8 hours, the patient’s puncture site near the proximal end, including the dorsal and radial along the direction of the cephalic vein appeared large erythema, erythema side
