Study on the relationship between skin cleaning status and wound infection after emergency treatment of skin wounds / 中国实用护理杂志

ABSTRACT

Objective:To analyze the relationship between skin cleaning status and wound infection after emergency treatment of skin wounds, so as to provide guidance for clinical work and home care of patients.Methods:Using retrospective research methods, a total of 349 patients with skin wounds admitted to the Department of Emergency Medicine of Lishui People′s Hospital from January 2016 to February 2022 were selected for cross-sectional investigation. And the wound-infected patients were set as the wound-infected group and the non-wound-infected patients were set as the non-wound-infected group. The patients′ clinical data, skin cleaning status and wound infection status were collected to compare the differences in the basic data between the two groups and further analyze whether there was an association between skin cleaning and wound infection using binomial Logistic regression.Results:There were 134 cases of wound infection in 349 patients with skin trauma, accounting for 38.40%, including 66 cases of acute wound infection and 68 cases of chronic wound infection.The cleaning frequency of 1 time/week, 2 times/week and ≥ 3 times/week in open wound bath cleaning was 2.99%(4/134), 0.74% (1/134) and 0 in the wound-infected group, respectively, which was significantly different from 2.79%(6/215), 7.91% (17/215) and 1.86%(4/215) in the non-wound-infected group ( χ2 = 11.42, P<0.05). Multifactorial analysis revealed that trauma area ≥8 cm 2, total cortical damage, long duration of trauma, and antibiotic treatment were independent risk factors for wound infection after emergency management of skin trauma ( OR values were 1.05-2.02, all P<0.05), the protective factors for wound infection after emergency treatment of skin trauma were bath cleaning of open wound and its cleaning times 2 times/week ( OR = 0.54, 0.62, both P<0.05). Conclusions:The choice of warm water bath cleaning after emergency treatment of skin trauma does not increase the risk of wound infection. On the contrary, it helps to prevent wound infection, but it should be noted that local disinfection should be carried out in time after the completion of cleaning.
