目的 应用不同冲洗液对慢性创面上应用的封闭负压吸引装置进行冲洗,对比两种冲洗方法的优劣,为临床应用提供参考。方法 对比两组冲洗液冲洗后创面肉芽组织生长情况,疼痛度,堵管率,住院天数,细菌培养及药敏试验结果等情况。结果 呋喃西林组对比于生理盐水组能更好的促进肉芽组织生长[(9.41±1.12) vs (7.76±0.67)],能缩短患者平均住院日[(29.44±1.88) vs (32.79±1.74)]d,但是对于减轻疼痛度、降低堵管率方面两者效果相当(P＞0.01)。同时细菌培养显示创面感染以革兰阴性菌为主,呋喃西林组细菌检出率低于生理盐水组(62.5% vs 82.5%);呋喃西林组部分细菌对呋喃西林产生耐药性,而生理盐水组这种情况较之少见(68% vs 36.36%)。结论 ①呋喃西林冲洗在促进肉芽组织生长,缩短平均住院日方面优于生理盐水组。②两种方法均能有效防止引流管的堵塞情况。③呋喃西林冲洗可降低细菌检出率,但能使部分细菌产生对呋喃西林的耐药性。

Objective: To compare the effects of two different liquid in negative pressure wound therapy for chronic wounds, provide the reference for clinical application. Methods: The growth of granulation tissue, pain degree, plugging rate, average hospitalization days, bacterial culture and drug sensitivity test results were compared after the two liquid was used. Results: Nitrofural group compared with the saline group can promote the growth of granulation tissue[(9.41±1.12) vs (7.76±0.67)], shorten the average days of hospitalization[(29.44±1.88) vs (32.79±1.74)]; but for the relief of pain degree and the plugging rate, the effects was similar(P＞0.01, the difference was not significant). At the same time, bacterial test showed that there were almost gram-negative bacteria, bacteria detection rate (62.5%) in Nitrofural group was less than that in the saline group (82.5%); Nitrofural group has more nitrofurazone resistant bacteria(68%), and the saline group performs not the same(36.36%). Conclusion: ① Furacilin irrigation could promote the growth of granulation tissue, shorten the average hospitalization days. ②The two methods can effectively prevent the blockage of the drainage tube. ② Furacilin irrigation can reduce the detection rate of bacteria, but cannot prevent the resistance of nitrofurazone.

目的 观察重组牛碱性成纤维细胞生长因子应用于治疗浅Ⅱ度烧伤创面的临床效果。方法 选取90例小面积浅Ⅱ度烧伤患者,随机平均分为2组:应用重组牛碱性成纤维细胞生长因子治疗的患者为治疗组,使用碘伏油纱治疗的患者为对照组,观察创面愈合时间、患者疼痛程度及远期色素沉着、瘢痕增生几率情况。结果 重组牛碱性成纤维细胞生长因子治疗组效果优于对照组,治疗组创面愈合时间(8.56±2.51)d短于对照组(12.42±2.13)d(P﹤0.05),平均愈合时间较提前3~5 d;患者疼痛度减轻[VAS评分分别是:(1.66±0.05)和(3.25±0.12),P﹤0.05];部分患者一年后随访发现治疗组远期色素沉着较轻,疤痕增生几率低。结论 应用重组牛碱性成纤维细胞生长因子治疗小面积浅度烧伤能够缩短创面愈合时间,在有效促进烧伤创面愈合同时,可减轻换药时疼痛,减轻远期色素沉着,降低瘢痕增生率。

Objective To observe effect of the recombinant bovine basic fibroblast growth factor in the treatment of superficial Ⅱ degree burn wounds. Methods Ninety cases of small area of superficial Ⅱ degree burn wounds were randomly divided into 2 groups: recombinant bovine basic fibroblast growth factor group(rb-bFGF) and control group (Iodophor gauze group). The wound healing time,patient pain, long-term hyperpigmentation and scar chance of proliferation were observed. Results The effect of rb-bFGF treatment group was better than that of control group. The healing time of the treatment group was (8.56 ± 2.51)d, it was shorter than that of the control group (12.42±2.13)d(P<0.01). The average healing time was 3~5 days, it was ahead of the control group; Compared to the control group, the rb-bFGF group had less pain (VAS scores were: 1.66±0.05 and 3.25±0.12,P<0.01); Some patients were followed up a year later, we found that the treatment group long-term pigmentation was lighter, scar chance of proliferation was lower. Conclusion Application of rb-bFGF in the treatment of small area of shallow Ⅱ degree of burns may shorten the wound healing time. As effective promotion of burn wound healing, it may reduce the pain when dressing, reduce long-term pigmentation and scarring rate.

目的 了解广东地区糖尿病足患者创面病原菌分布及耐药性变迁。方法 回顾性分析A组(2010年1月—2014年12月就诊的糖尿病足患者)和B组(2015年1月—2018年1月就诊的糖尿病足患者)研究者创面病原菌分布及耐药性变迁。结果 B组中创面G⁺菌及G^-菌均有下降趋势且G^-菌下降较快,细菌种类明显增加,真菌及混合感染明显上升,A组以金黄色葡萄球菌、铜绿假单胞菌、大肠埃希菌感染为主;B组以金黄色葡萄球菌、奇异变形杆菌、铜绿假单胞菌及真菌感染为主;B组相对于A组的细菌耐药性增加。结论 近年来糖尿病足患者病原菌种类明显增加且混合感染及真菌感染上升,且其耐药性增加,因此早期经验用药而后根据药敏选择抗菌药物治疗是糖尿病足感染治疗的关键。

Objective To investigate the distribution and drug resistance of pathogenic bacteria in diabetic foot wounds in Guangdong area. Methods Patients with diagnosis of diabetic foot between group A (from Jan 2010~Dec 2014 ) and group B (from Jan 2015 to Jan 2018) were retrospectively analyzed. We studied the bacteria distribution and drug resistance of pathogenic changes of group A and group B. Results In group B, both G+ and G- bacteria had a decreased trend while G- bacteria decreased rapidly, but the species of bacteria increased obviously just as fungi and mixed infection increased obviously. Bacteria infection in group A were mainly about Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli wihle group B were Staphylococcus aureus, Proteus mirabilis, Aeruginosa and Fungal infection; the resistance of group B to A was lower. Conclusion In recent years, kinds of pathogenic bacteria of diabetic foot were significantly increased and the mixed infection and increased fungal infection as well as its drug resistance increased, so the early experience of medication choice of antibiotics based on drug sensitivity and treatment are the key to the treatment of diabetic foot infection.
