静脉炎的护理措施有哪些
参考答案：答：预防静脉炎的方法有严格无菌技术操作，对血管壁有刺激性的药物应充分稀释后再应用，放慢点滴速度，并防止药液漏出血管外。同时，有计划地更换输液部位，以保护静脉。一旦发生静脉炎，可采取以下方式处理：①停止在此部位静脉输液，并将患肢抬高、制动；局部用50％硫酸镁或95％乙醇溶液行湿热敷，每日2次，每次20分钟。⑦超短波理疗。⑧中药治疗，如意金黄散外敷，每日2次。④如合并感染、遵医嘱给予抗生素。

| The moon is the earth's largest and only natural satellite. A satellite is a small body that goes around a planet. The first man-made satellite went into the orbit in 1957. By 1968 there were over three hundred satellites in the orbit. Some satellites send back weather pictures. Others send out radio waves. Some satellites are what we call "junk". In 1963, the United States put millions of small pieces of wire into orbit. They were used to carry radio waves. Many of these wires may still be there. Some space junk was not put in the orbit. For example, one piece of space junk is a glove lost by an astronaut! Space is very big. Does it matter if there is junk in the orbit? Many scientists think so. They say we must pay much attention to how we use this new resource. They think anything man puts into space should be made to come back to earth when its work is done. They say it's dangerous to have space junk, because it's possible for spacecraft to collide with the junk. |
