目的探讨紫外线空气消毒机应用于连台手术间隙空气消毒的效果。方法选择医院2013年1月-2014年1月连续2台手术且手术时间为2~3 h的择期手术120例为对象,随机分别为实验组与对照组,实验组应用紫外线空气消毒机在连台手术间隙对手术间进行空气消毒,对照组不做消毒处理。分别在前一台手术结束后、消毒后30 min,第二台手术切皮时,第二台手术开始后30 min,第二台手术结束时分别对空气进行采样。结果两组在前一台手术结束时菌落数比较没有统计学意义,在消毒后30 min,实验组为73.88±15.76 cfu/m3,对照组为142.75±33.91 cfu/m3,两者比较差异具有统计学意义(P<0.05)。结论紫外线空气消毒机应用于连台手术间隙空气消毒具有很好的效果,可以提高空气洁净度,对手术部位感染预防与控制具有重要意义。
Objective To investigate the effect of ultraviolet air disinfection machine on air disinfection even with the operation of the gap. Methods A total of 120 elective surgery patients from January 2013 to January 2014 in our hospital from January 2013 to January 2014 were enrolled in this study. 120 patients undergoing elective surgery between 2 and 3 hours were randomly divided into experimental group and control group. The experimental group was treated with ultraviolet air disinfector Taiwan surgery gap between the air disinfection of surgery, the control group does not do disinfection. At the end of the previous surgery, 30 min after disinfection, the second surgical incision, the second after the start of surgery 30 min, the second end of the surgery when the air sampling. Results The number of colonies in the two groups was not statistically significant at the end of the previous operation. At 30 min after disinfection, the experimental group was 73.88 ± 15.76 cfu / m3, while the control group was 142.75 ± 33.91 cfu / m3. The differences between the two groups were statistically significant Significance (P <0.05). Conclusion The application of UV-air disinfector has the good effect of air disinfection even with the surgical gap, which can improve the cleanliness of the air and is of great significance for the prevention and control of infection in the surgical site.
