Abstract: Objective To analyze dialysis device adverse events via intensive monitoring. Methods To monitor 9 second-class hospitals randomly in Guangdong province, and to record the information of equipments and materials used by each dialysis patients in details with excel software and then to analyze the statistics. Results There are altogether 51 adverse events among 40 120. The main manifestations are dysarteriotony, suppression in the chest, vomiting, blood coagulation and air embolism. It is suspected that they are mainly caused by equipment materials and failures as well as irregular visits by the patients. Usually the measures taken to handle these performances are to terminate dialysis and ask the patients to have a good rest. Till now no death occured. Conclusion There has been no adverse events in Guangdong province till now. But as a regular treatment, with its increasing application and popularization of dialysis, suspected dialysis adverse events will increase, which will directly affect the life quality and even safety of patients. But because of medical workers' different views and vague understanding of adverse events, they may underreport or even fail to report these adverse events. Therefore, vocational training of monitoring workers at the grassroots level has to be strengthened, discriminating and analyzing ability of dialysis medical workers have to be improved and monitoring work has to be continued. So that administrative departments can take relevant executive measures to tackle potential events and offer scientific evidence for these measures. Ultimately adverse events can be timely and effectively controlled and prevented.
