又到了寒冷的冬季,尤其是在北方,刺骨的寒冷让人们不要说献血,就是出门也带着几分犹豫。根据以往的经验,我国北方很多地方因为人们不愿意献血而导致供血紧张。然而病人需要输血却不会因为冬天而停止,仍然需要我们挽起袖子去拯救生命。那么,这个季节献血需要注意那些问题呢?有些什么讲究呢?冬季温度的降低必然导致血管收缩,而天冷人们活动量减少也是一个原因,这就增加寻找血管的难度。因此献血前要想办法扩张血管,在温度较低的环境下献血,献血者可以饮上一杯热水以促进血液循环,或者轻轻拍打肘部使血管充盈。由于天气寒冷,因此献血后,除了常规注意事项外,一定注意不要着凉,避免感冒。
It was cold winter, especially in the north, where the biting cold kept people from giving blood, leaving home with a bit of hesitation. Based on past experience, blood supply was strained in many parts of northern China because people did not want to donate blood. However, patients who need blood transfusions will not stop because of the winter and still need us to roll up their sleeves to save lives. Well, blood donation this season need to pay attention to those issues? What are some stress? Winter temperatures will inevitably lead to vasoconstriction, and cold weather is also a reduction in activity is one reason, which increases the difficulty of looking for blood vessels. Therefore, before blood donation to find ways to dilate blood vessels, donate blood in a lower temperature environment, blood donors can drink a cup of hot water to promote blood circulation, or gently tap the elbow to fill the blood vessels. Due to the cold weather, blood donation, in addition to the usual precautions, must be careful not to catch cold and avoid cold.
