慢性伤口感染病原菌分布与银离子抗菌敷料应用探讨

Study on Application of Chronic Wound Infection Bacterial Distribution and Silver Ions Antibacterial Dressings

目的分析慢性伤口感染病原菌分布情况,观察应用银离子抗菌敷料治疗的效果。方法整群选择该院2016年1—12月接收的慢性伤口感染患者362例,均收集伤口标本给予病原菌检测,并利用银离子抗菌敷料治疗,观察检测结果及治疗效果。结果经检测,检出病原菌230株,检出率63.5%(230/362)。230株病原菌中,革兰阴性菌119株,占51.8%;革兰阳性菌104株,占45.2%;真菌7株,占3.0%。经治疗,治疗有效率96.1%(348/362);感染控制时间(11.7±2.6)d;换药次数(5.2±0.9)次;局部症状消退时间(4.8±1.6)d;住院时间(10.2±1.5)d。结论慢性伤口感染主要病原菌为革兰阴性菌,利用银离子抗菌敷料治疗后,可有效消除感染症状,促进伤口愈合。

Objective To analyze the chronic wound infection bacterial distribution and the treatment effect of silver ions antibacterial dressings. Methods Group selection 362 cases of patients with chronic wound infection admitted and treated in our hospital from January to December 2016 were selected and the wound specimens were collected and given the bacterial test, and treated with silver ions antibacterial dressings, and the test results and treatment effect were observed. Results 230 strains of pathogenic bacteria were tested and the test rate was 63.5%(230/362), of 230 strains of pathogenic bacteria, there were 119 strains of gram negative bacteria, accounting for 51.8% and 104 strains of gram positive bacteria, accounting for45.2% and 7 strains of fungi, accounting for 3.0%, after treatment, the treatment effective rate, infection control time, frequency of dressing change, local symptoms subsided time and length of stay were respectively 96.1%(348/362),(11.7±2.6)d,(5.2±0.9)times,(4.8±1.6)d,(10.2±1.5)d. Conclusion The main pathogenic bacteria of chronic wound infection is gram negative bacteria, and the treatment of silver ions antibacterial dressings can effectively eliminate the infection symptoms and promote the wound healing.
