A Newly Invented Antibacterial in Decontamination of Reusable Hospital a Device

Abstract

Hospitals have sanitation protocols regarding uniforms, equipment sterilization, washing, and other preventive measures. Thorough hand washing and/or use of alcohol rubs by all medical personnel before and after each patient contact is one of the most effective ways to combat nosocomial infections. More careful use of antimicrobial agents, such as antibiotics, is also considered vital. We collected a variety of previously used medical devices, 18 pieces (tubing system of ventilator, face masks , blades of laryngoscope and stethoscope bell & diaphragm).After These devices had been cleaned ,rinsed then immersed in bleach ,we tested their decontamination using a newly invented antibacterial; we  used  different weight of Sidr leaves aqueous extract 50g/L, 62.5 g/L, 75g/L and 87.5 g/L  (w/v) and a mixture of the two chemicals ;the extract and hydrogen peroxide 1.5% while normal saline 0.9% was used as control. . The process of testing decontamination was repeated as the period of contact between the devices and any of the fourth disinfectants was increased starting at 5 ,then increasing to 15and 30 minutes successively . Loopful swabs were taken from the devices before and after contact with the disinfectants and repeated as the period of contact was increased to 15 then 30 minutes.

Mixing hydrogen peroxide 1.5% (v/v) and aqueous sidr extract 62.5 g/L(w/v) was effective in eradicating contamination of used contaminated medical devices after a period of contact of 30 minutes.

The new antibacterial agent is effective in decontaminating reusable medical devices after 30 minutes of contact.
