改良式骨牵引装置在下肢骨牵引患者中的应用

Application of modified bone traction device in patients with lower limb bone traction

目的探讨改良式骨牵引装置用于下肢骨折患者的效果。方法选取2021年3月至12月在上海交通大学医学院附属第六人民医院行下肢骨牵引的患者120例,采用随机数字表法将其分为改良组和对照组,每组60例。对照组采用传统骨牵引装置进行骨牵引,改良组采用改良式骨牵引装置进行骨牵引。采用数字评定量表(NRS)评估两组牵引前及装、卸牵引弓时的疼痛程度,采用舒适状况量表(GCQ)评估两组牵引前后的舒适度,比较两组骨牵引装置的操作时间、渗血量、压力性损伤发生率及住院患者的满意度。结果两组装、卸牵引弓时的NRS评分均高于本组牵引前,改良组装、卸牵引弓时的NRS评分低于同期对照组,差异统计学意义(P<0.05)。牵引后,两组GCQ评分均低于牵引前,改良组高于对照组,差异有统计学意义(P<0.05)。改良组骨牵引装置操作时间短于对照组,渗血量低于对照组,住院患者满意度优于对照组,差异有统计学意义(P<0.05)。两组压力性损伤发生率比较,差异无统计学意义(P>0.05)。结论改良式骨牵引装置应用于下肢骨牵引患者可减轻疼痛,节约操作时间,提高舒适度与满意度。

Objective To explore the effect of modified bone traction device on patients with lower limb fractures.Methods A total of 120 patients who underwent bone traction of lower limb in the Sixth People’s Hospital Affiliated to the Medical College of Shanghai Jiao Tong University from March to December 2021 were selected and divided into improved group and control group by random number table method,with 60 cases in each group.The control group used traditional bone traction device for bone traction,and the improved group used modified bone traction device for bone traction.Numeric rating scale(NRS)was used to evaluate the pain level before traction,loading,and unloading of traction arch,and general comfort questionnaire(GCQ)was used to evaluate the comfort of the two groups before and after traction.The operation time of bone traction device,the amount of bleeding,the incidence of pressure injury,and the satisfaction of hospitalized patients were compared between the two groups.Results The NRS scores of the two groups during loading and unloading of the traction arch were higher than those before traction,and the NRS scores of improved group were lower than those of the control group during loading and unloading of the traction arch,and the differences were statistically significant(P<0.05).After traction,the GCQ scores of the two groups were lower than those before traction,and the GCQ scores of the improved group were higher than those of the control group,and the differences were statistically significant(P<0.05).The operation time of the bone traction device in the improved group was shorter than that in the control group,the amount of bleeding was lower than that in the control group,and the satisfaction of hospitalized patients was better than that in the control group,and the differences were statistically significant(P<0.05).There was no significant difference in the incidence of pressure injury between the two groups(P>0.05).Conclusion The application of modified bone traction device in patients with lower limb bone traction can reduce pain,save operation time,and improve comfort and satisfaction.
