便携式负压创面治疗技术在门诊下肢静脉溃疡患者的应用

目的 探索分析便携式负压创面治疗技术在门诊下肢静脉溃疡患者中的应用效果。方法 选取2021年10月~2022 年 9月南昌大学第二附属医院伤口造口门诊收治的 60例下肢静脉溃疡患者为研究对象，按照入院前后顺序将其分为对照组（30例）和观察组（30例）。对照组采用常规伤口换药护理，观察组采用便携式负压创面治疗技术。治疗1个月后，比较两组患者创面面积、创面治疗疗效、疼痛程度变化。结果 两组患者创面面积变化的时间、组间和交互作用比较，差异有统计学意义（P＜0.05）。进一步进行两两比较，组内比较结果显示：两组治疗后第14、28 d的创面面积均低于本组治疗前，治疗后第28 d的创面面积均低于治疗后第14 d，差异有统计学意义（P＜0.05））。组间比较结果显示。两组治疗前创面面积比较，差异无统计学意义（P＞0.05）。观察组治疗后第14、28 d的创面面积低于对照组，差异有统计学意义（P＜0.05）；观察组的创面治疗疗效总有效率为 90%，高于对照组的 66.67%，差异有统计学意义（P＜0.05）；观察组疼痛评分低于对照组，差异有统计学意义（P＜0.05） 结论 应用便携式负压创面治疗技术对门诊下肢静脉溃疡患者的伤口进行处理，能够加快伤口的愈合、缩小创面面积，增加患者舒适度、减轻疼痛，具有推广应用价值。

APPLICATION OF PORTABLE NEGATIVE PRESSURE WOUND THERAPY IN OUTPATIENT PATIENTS WITH VENOUS ULCER OF LOWER EXTREMITY

Objective: To explore and analyze the application effect of portable negative pressure wound therapy in outpatient patients with venous ulcer of lower extremity. Methods: Sixty patients with venous ulcers of lower extremity admitted to the Wound Ostomy Clinic of the Second Affiliated Hospital of Nanchang University from October 2021 to September 2022 were selected as the research objects, and were divided into control group (30 cases) and observation group (30 cases) according to the order before and after admission. The control group received conventional wound dressing change nursing, and the observation group received portable negative pressure wound therapy. After 1 month of treatment, the changes of wound area, therapeutic effect and pain degree were compared between the two groups. Results: There were statistically significant differences in the time, intergroup and interaction of wound area change between the two groups (P < 0.05). Further pairwise comparison was conducted, and the results of intra-group comparison showed that the wound area of the two groups on the 14th and 28th day after treatment was lower than before, and the wound area on the 28th day after treatment was lower than that on the 14th day after treatment, with statistical significance (P < 0.05). The results of intergroup comparison showed that there was no significant difference in the wound area between the two groups before treatment (P > 0.05). The wound area of the observation group was significantly lower than that of the control group at the 14th and 28th days after treatment (P < 0.05). The total effective rate of wound treatment in the observation group was 90%, significantly higher than that in the control group (66.67%) (P < 0.05). Pain score of observation group was significantly lower than control group (P < 0.05). Conclusion: The application of portable negative pressure wound therapy for the wound treatment of patients with venous ulcer of lower extremity in outpatient department can accelerate the wound healing, reduce the wound area, increase the comfort level of patients and reduce the pain, which has the popularization and application value.
