Evaluation of various Chemicals and Disinfectants for their Antimicrobial activity.
Pak Armed Forces Med J Jan ;47(2):54-8.

The study was conducted to determine the antibacterial activity of commonly used disinfectants in the generally employed dilutions and the effect of storage on their efficacy. The disinfectants tested were chlorhexidine gluconate, povidone-iodine, ethyl alcohol, 2% glutaraldehyde, phenol, lysol and savlon (cetrimide + chlorhexidine gluconate). Various tests done were the Kelsey Sykes capacity test, Rideal Walker test, quantitative suspension test, in-use test and stability test. The results showed that all these disinfectants were effective in their recommended concentrations. Chlorhexidine gluconate and povidone iodine can be used for the disinfection of skin and scrubbing hands prior to surgery, bladder irrigation & catheterization. 2% glutaraldehyde is cost of fective disinfectant and can be used for the disinfection of medical equipment like cystoscopes, bronchoscopes and decontamination in laboratories. Lysol should be preferred over phenol for cleaning floors, and walls. Savlon is not recommended for the disinfection of skin as it is liable to become contaminated with Pseudomonas aeruginosa. Further studies are required to evaluate these disinfectants when applied to the real life situations.
