静脉留置针操作与维护【护理ppt课件】
留置针谁都会打，但堵管、静脉炎、外渗这些并发症，全部都出在细节上。
回血不等于穿刺成功，回血只说明针尖入血管，但软管可能还没跟上，必须压低角度再进1-2mm，确认软管完全入血再退针芯。贴膜必须无张力，拉紧贴就是张力性水泡，从中心往四周自然抚平。冲管要脉冲式，匀速推冲不干净，推一下停一下形成湍流才管用。封管边推边拔，松手再夹夹子负压回血直接堵管。
红线别碰：堵管严禁硬冲，血栓入肺就是栓塞，抽不出回血直接拔了重打；1级静脉炎见红即拔，没得商量；消毒液没干透别穿刺，不然化学性静脉炎等着你。选针原则是在满足治疗的前提下最细最短，导管外径不超过静脉内径1/3，留够血流空间，静脉炎几率将会大幅下降
