Antiseptics have a major role against the infections and their prevention. The good management of antiseptics allows the reduction of antibiotics use and thus the emergence of resistant bacterial strains. The evaluation of the antibacterial activity of three antiseptics (povidone iodine [PVPI], iodized alcohol and alcohol 70 degrees) used at HMIMV and taken from pharmacy was based on AFNOR method NF T 72-150. The analysis of their chemical properties were done by standardized methods (manganimetry, Bunsen's method, test to determine sodium thiosulfate levels [or sodium thiosulfate test] and Guy Lussac alcoholmeter). Our results were compared with those obtained in another two university hospitals of Rabat: Hospital of Speciality and Ibn Sina. The frequencies of resistant bacterial strains were respectively 4.6%, 30.7% and 15.4% to PVPI, alcohol iodized and alcohol 70 degrees . Our results have shown that the PVPI is the best antiseptic in our hospital.
