摘要目的:探讨自制系带固定器在肢体骨折术后切口周围全纱带覆盖时引流管二次固定中的临床应用效果。方法:选取2019年10月至2020年6月创伤外科收治的120例肢体骨折行内固定术后切口周围全纱带覆盖的留置引流管患者，采用抽签法分为对照组50例和试验组70例。对照组使用传统3M胶带高举平台法固定引流管，试验组使用自制系带固定器固定引流管。观察并比较2组固定效果的不同。结果:试验组患者导管相关风险事件发生率为1.4%（1/70），低于对照组14.0%（7/50），差异有统计学意义（ χ2值为7.408， P=0.009）；固定材料更换间隔时间（5.10 ± 0.39）d，明显高于对照组（1.68 ± 0.23）d，差异有统计学意义（ t值为60.168， P<0.001）；固定材料复用率为97.1%（68/70）、舒适度为97.1%（68/70），均高于对照组0、48.0%（24/50），差异有统计学意义（ χ2值为112.00、39.37， P<0.001）。 结论:自制系带固定器在肢体骨折术后切口周围全纱带覆盖时引流管二次固定中，固定效果可靠，可有效减少导管相关风险事件的发生，具有可行性和安全性。

abstractsObjective:To investigate the clinical application effect of self -made frenum fixator in the secondary fixation of drainage tube with full gauze coverage around the incision after limb fracture surgery. Methods:120 cases of patients with limb fracture treated by trauma surgery from October 2019 to June 2020 were selected and divided into control group (50 cases) and experimental group (70 cases) by drawing lots. The control group used the traditional 3M tape platform method to fix the drainage tube, and the experimental group used the homemade lace up fixator to fix the drainage tube. The difference of fixtion effect between the two groups was observed and compared.Results:The incidence of catheter-related risk events was 1.4% (1/70) in the experimental group, which was lower than 14% (7/50) in the control group (2 value was 7.408, P = 0.009); the change interval of fixation materials was (5.10±0.39) d, which was significantly higher than (1.68±0.23) d in the control group ( t value was 60.168, P<0.001); the fixed material reuse rate was 97.1% (68/70) and comfort 97.1% (68/70), which were higher than 0 and 48.% (24/50) in the control group, the differences were statistically significant (2 values were 112.00 and 39.37, P<0.001). Conclusion:The self -made lace up fixator has reliable fixation effect and can effectively reduce the occurrence of catheter -related risk events. It is feasibility and safety.
