Abstract

تهدف هذه الدراسة إلى تقييم مدى فاعلية وتأثير بعض المطهرات والمعقمات المستخدمة في المرافق الصحية، وخصوصًا في مستشفى مصراتة المركزي، بحسب التراكيز المعدّة لهذه المرافق، على مجموعة البكتيريا الزائفة () المعزولة من قسم الولادة ووحدة العناية المركّزة للأطفال حديثي الولادة بمستشفى مصراتة المركزي، في الفترة من 11 أكتوبر2017 إلى 8 مارس 2018، مع العامل الزمني لهذا التأثير، حيث كانت الأنواع المعزولة هي ()، ()، ()، ()، ()، (). وباستخدام أقراص ورق الترشيح المشبعة بالمعقم (Disk diffusion)، وكانت المعقمات والمطهرات، هي: (Ethanol)، (NaClO)، (Propanol AF)، (Desreson AF)، (Cidex)، (Decosept)، (Minuson AF)، (Dettol)، أظهرت النتائج تأخرًا في تأثير هذه المعقمات؛ إذ لم يظهر أي تأثير قبل 20 دقيقة من التعريض، وكان أكثرها فاعلية مطهر (Cidex) عند 20 دقيقة ضد الأنواع الثلاثة () و() و()، ثم بعد 24 ساعة لوحظت فاعلية جيدة على أغلب الأنواع للمعقمات (Decosept) و(NaClO) و(Dettol) و(Derseson)، ولكن ليس على كل الأنواع، مع فاعلية جيدة لمعقم (Propanol) على كل الأنواع، وتأثير خفيف لمطهر (Ethanol) ابتداء من الدقيقة 20، وانعدام أي تأثير لمعقم (Minuson) على هذه الأنواع، حيث تراوح حجم الهالة على هذه البكتيريا من 3 مليمترات إلى 2.5 سنتيمتر.

This study aimed to evaluate the effectiveness and impact of some disinfectants and sterilizers used at health facilities, especially in Misurata Central Hospital, Libya. The study examined the concentrations prepared for usage at these facilities and the time factor of their effectiveness on a group of Pseudomonas bacteria isolated from the Maternity Department and the Neonatal Intensive Care Unit in this Hospital (11 October 2017 to 8 March 2018). The isolated bacteria species were: , , , , , . The study used disinfectants impregnated with filter paper discs (disk diffusion). The disinfectants used were: Ethanol, NaClO, Propanol AF, Desreson AF, Cidex, Decosept, Minuson AF and Dettol. : The results showed a delay in the effectiveness of these sterilizers. None of them showed any effect during the first 20 minutes of exposure. The most impactful disinfectant at 20 minutes was Cidex against the three types of bacteria: , , and . Twenty four hours later, good efficacy was observed for most of the sterilizers such as Decosept, NaClO, Dettol and Desreson AF, but not on all types of bacteria. Propanol AF sterilizer showed good efficacy on all species, while Ethanol showed slight results starting from minute 20. However, Minuson sterilizer showed no effects on these species. The diameter of the inhibition area on these types of bacteria ranged from 3 mm to 2.5 cm.
