安全静脉留置针留置时间及相关因素研究

Study on the indwelling time of intravenous catheter system and relatively factors

目的探讨不同因素对静脉留置针留置时间及并发症的影响。方法选择静脉留置针205例,从卧床与非卧床、高渗与低渗、不同封管液及不同部位留置时间及其相关因素进行临床观察。结果留置时间不受体位及穿刺部位的影响(P>0.05);留置时间与液体渗透压及封管液有关(P<0.05);肿胀发生与液体渗透压及体位有关(P<0.05);静脉炎的发生与渗透压有关(P<0.01),与体位无关(P>0.05),且肿胀发生率明显高于静脉炎发生率(P<0.01)。结论静脉留置针不受体位及活动影响,只要治疗及病情需要可随时选择静脉留置;输入高渗液体应3d更换留置部位1次,并适当活动留置肢体,以减少肿胀及静脉炎的发生。

Objective To study the effect of different factor to the time of intravenous catheter system and complication. Methods Choose 205 cases with integrate catheter. Not lie in bed and lie in bed , High exudation and low exudation, different sealing solution and different indwelling position are observed. Result The indwelling time is not affectd by the body position and injection position（ P 〉 0.05 ） ; It is related to the liquid filter press and sealing liquid（ P 〈 0.05） ;The swelling relates to the liquid filter press and （ P 〈 0.05） ; the emergence of the phlebitis relates to high exudation （ P 〈 0.01） ;Having no relations with body position（ P 〉 0.05） ;And the rate of swelling incidence is obviously higher than the phlebitis incidence （P 〈 0.01 ）. The indwelling of intravenous catheter system is not influenced by body position and activity. It can be indwelled at any time for the need of treatment and patient＇s condition .It can indwelling at any time. In order to reduce the emergence of the swelling and phlebitis, the injection location should be changed for every three day and the indwelling limbs should be activated when patient were injected high to exude.
