供应室消毒工作是预防和控制医院感染的必要手段，加强对化学消毒剂的严格管理和合理使用又是取得最佳消毒效果的重要保证。因此在消毒剂的选择和使用上应加强管理，严格把关
Objectives To compare umbilical cord daily care protocol in the current clinical setting in which 75% alcohol sterile is used daily for the umbilical and surrounding skins with the WHO-recommended method (dry and clean). Methods A total of 283 full-term newborns were randomly divided into two groups: the trial group (n=181) receiving WHO “dry and clean” protocol that the umbilical cord was open to air (with losing clothes), cleaned by clear water instead of alcohol. The control group (n=102) used the traditional method that after the newborns’ bathing, the umbilical cord and surrounding skins were sterilized with 75% alcohol. The basic condition of the newborns, umbilical departure time and complications around the navel were assessed. And bacterial culture from the newborns’ skins was observed. Results There were no significant differences in departure time of the umbilical cord (7.64±3.29 day vs. 8.50±3.45 days t=1.82, Pgt;0.05), complications (6 patients with slight omphalitis in the trial group and 2 patients with slight omphalitis in the control group), and the skin flora culture between the two groups. The umbilical cord of the newborns dropped off safely. And no fever was found. Conclusion This study does not support that 75% alcohol can prevent the umbilical cord from being infected. Keeping the umbilical cord and surrounding skins dry is important for infection control.
Objective To find effective ways for controlling the hospital infection to the skeptical gas gangrene patients. Method From May 14th to June 24th, the hospital set up triage spots originally and dealt with the wounded based on their specific conditions in different stages and optimized the flow of admission of the wounded. Owing to correctly treating the wound and screening the skeptical gas gangrene patients, preventing nosocomial infections was shifted forward. Sprending the gas gangrene wound after having flushed it with 3% H2O2. If the wound have been stitched, the stitches should bee taken out, and open the wound and take the debridement for it completely, then treat it with b antibacterial after debridement by sterilization and isolation about operation of gas gangrene. Result Up to June 24th, none of 67 cases of doubtful gas gangrene from the disaster area died and no hospital cross infections happened in courtyard. At present, amomg the 67 cases, 32 were highly suspected of gas gangrene infection, 26 cases were discharged, while 6 cases were undergoing treatment in the hospital. Conclusion Correct management and appropriate treatment are effective ways for controlling hospital cross infection to the skeptical gas gangrene patients.
Objective To provide the evidence for anti-epidemic command and developing response plan through investigation on prophlactical disinfection in Deyang, the worst-hit areas after Wenchuan earthquake. Methods We used convenient sampling together with the report forms and the self-made questionnaire to collect information from 107 villages and 17 settlement spots for the disaster victims in 25 towns in Deyang disaster area. Results There were a total of 6 kinds of disinfectant, including the chlorine disinfectant, 2 kinds of peroxide disinfectant and 2 other types of disinfectant, which were delivered the Deyang disaster area through the National amp; Province CDC system allocation or the None-Goverment Organization donation. From May 17 to June 9, the large-scale preventive disinfection was carried out in the disaster area, covering tap water, the restroom and the latrine pit, trash, environment and sewage. All personnel who conducted the disinfection for prevention and public health in the villages and towns received the technical training for disinfection. Conclusion Various disinfectant types and difference specifications cause trouble in the training of manpower and the use of disinfectant. Preventive disinfection in the most serious disaster areas is better than in serious disaster areas. The main channel of obtaining the disinfectant is through the National amp; Province CDC. The daily-report system of the disinfected areas may monitor the progress of disinfectant use. The suitable disinfection may prevent the public health secondary disaster and protect the environment effectively.
目的 评价LB-SDS2.0型酸性氧化电位水生成机生成的酸性氧化电位水对皮肤（手）消毒的有效性和安全性。 方法 2006年2月－8月将90例健康志愿受试者随机分为3组，各组30例。A组用LB-SDS2.0型酸性氧化电位水生成机生成的酸性氧化电位水（试验产品）消毒2 min，B组用试验产品消毒4 min，C组（对照组）用聚维酮碘溶液擦拭3 min。检测消毒后菌落总数和致病菌，以及受试者不良反应情况。 结果 按照Ⅲ类区域工作人员洗手消毒标准，A、C组合格率均为100%，B组为96.7%；按照Ⅰ、Ⅱ类区域工作人员洗手消毒标准，A组合格率为86.7%；B组合格率为93.3%，C组合格率为100%。各组受试者试验后生命体征均无临床意义的改变，未出现任何不良反应。 结论 试验产品消毒手是安全有效的，可推荐用在Ⅲ类区域工作人员中使用，并进一步观察其安全性和有效性。建议扩大样本含量进一步评价其试验产品是否适用于Ⅰ、Ⅱ类区域工作人员洗手消毒。
目的 分析多功能空气消毒机在普通内科病房的动态消毒效果，为病房空气质量的控制提供参考依据。 方法 2010年9月－2011年4月对普通内科病房在动态状态下进行细菌检测并使用多功能空气消毒机消毒，并就消毒前后的空气细菌菌落总数进行分析比较。 结果 在动态状态下，病房关门关窗并开启空调机时，使用多功能空气消毒机消毒前的空气细菌菌落总数显著高于消毒后，差异有统计学意义（P＜0.05）；病房在开门开窗时，使用多功能空气消毒机消毒前后的空气细菌菌落总数比较，差异无统计学意义（P＞0.05）。 结论 普通内科病房在关门关窗并开启空调机动态状态下，使用多功能空气消毒机可以降低空气细菌菌落总数，改善房间空气质量。
目的 探讨消毒供应中心的管理方法，切实提高其质量。 方法 2008年8月－2010年12月应用PDCA循环管理模式，对消毒供应中心实施标准化、规范化、系统化和科学化的管理。 结果 应用PDCA循环管理模式以来，消毒供应中心的建筑布局及工作流程得以规范；手术器械处置效率、清洗消毒灭菌质量得以提高；手术切口、Ⅰ类手术切口的感染率均得以降低。2009年与2008年、2010年与2008年比较，手术切口感染率均得以降低，差异有统计学意义（χ2=39.95，P＜0.05；χ2=27.80，P＜0.05）；2009年与2010年比较，手术切口感染率差异无统计学意义（χ2=0.02，P＞0.05）。2009年与2008年、2010年与2008年、2010年与2009年比较，Ⅰ类手术切口感染率降低，但差异无统计学意义（χ2=2.83，P＞0.05；χ2=2.21，P＞0.05；χ2=0.05，P＞0.05）。 结论 推行PDCA循环管理模式，促进了消毒供应中心的规范化管理，实现了消毒器械质量控制的前馈控制、过程控制以及反馈控制；拓展了消毒供应专业领域，使医院的现有资源得到了最为高效的利用；使患者安全得到了切实保障。
