【Abstract】 Investigation on bacterial and HBsAg contamination of disinfectant solution in use was carried out in hospitals of Linyi Prefecture. Of 384 samples examined, rate of bacterial contamination beyond permissible limit was 22.14%(total bacterial count exceeding 250/ml was considered as beyond permissible limit), and positive rate for HBsAg was 17.19%. It was indicated in the investigation that:(1) the contamination in hospitals of villages and towns was heavier than that in hospitals of cities;(2) among solutions of various disinfectants such as bromogeramine, ethyl alcohol, tinctura iodi, peracetic acid and sodium dichloroisocyanurate, the solutions of ethyl alcohol and peracetic acid were most frequently contaminated;(3) the longer the duration of use, the heavier the contamination;(4) the chance of contamination would increase if the container had not been cleaned and disinfected during change of disinfectant solution;(5) the HBsAg positive rate of the disinfectant solution used to disinfect invasive instruments was higher than that used to disinfect ordinary instruments(25.83% vs 8.63%) because the HBV in patient blood was likely to be carried into the disinfectant solution in the former case.更多还原
