Q—SyteTM分隔膜无针接头在术后留置中心静脉导管患者中的应用

目的观察Q SyteTM分隔膜无针密闭式输液接头在外科大手术后中心静脉置管患者中的应用效果。方法将112例应用中心静脉导管（CVC）进行输液的患者，按随机数字表法随机分为观察组和对照组各56例。观察组使用Q SyteTM接头，对照组使用原装肝素帽。观察两组发生管腔回血、管腔堵塞、管道脱落、导管感染、意外针刺伤及液体流速等情况。结果观察组在管腔回血、管腔堵塞、导管感染、管道脱落发生等方面均低于对照组，差异具有统计学意义（χ2=27.24，4.35，5.49，7.73；P〈0.05或P〈0.01）。观察组护士的意外针刺伤发生率为0.00%，护理时间为（2.2±0.7）min，分隔膜无针接头的留置时间为（7.7±2.1）d，对照组分别为10.71%，（6.7±1.2）min，（4.1±1.8）d，两组比较差异均有统计学意义（χ2=4.4，t值分别为24.4，-9.7；P〈0.05）。结论Q SyteTM分隔膜无针输液接头能有效阻止中心静脉导管血液回流、降低感染率、避免护士针刺伤，且方便连接和操作，在临床静脉输液中值得推广和应用。

Application of Q-SyteTM split septum needleless connector in patients with detained central venous catheter after surgery

Objective To study the application of Q-SyteTM split septum needleless closed style transfusion connector in patients with detained central venous catheter （CVC） after surgery. Methods 112 patients using central venous catheter for transfusion were randomly divided into two groups, the observation group and the control group, each with 56 cases each. Q-SyteTM and Heparin cap were used in the observation group and the control group respectively and their effect on the back blood, obstruction, infusion tube shedding, catheter infection, pricking wound and liquid flow rate was observed and compared. Results The incidence rates of back blood, obstruction, catheter infection, infusion tube shedding were all statistically significantly lower in the observation group compared to the control group （ χ2 = 27.24, 4.35, 5.49, 7.73, respectively ; P 〈 0. 05 or P 〈0.01 ）. The incidence rate of pricking wound, nursing time and detaining duration of the connector were 0.00%, （2.2 ± 0.7 ） min and （7.7 ± 2.1 ） d respectively, in the observation group, while those in the control group were 10.71%, （6.7 ± 1.2）min and （4.1 ± 1.8）d, respectively, and the differences were statistically significant （ χ2 = 4. 4 ; t = 24. 4, - 9. 7, respectively; P 〈 0. 05 ）. Conclusions Q-SyteTM is worthy of application and popularization in clinical intravenous transfusion as it can effectively prevent the back blood in central venous catheter, reduce infection incidence rate, avoid pricking wounds, and is easy to operate.
