RESUMEN
Objective: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.
