ABSTRACT
Objective To investigate the status of treating precision surgical instruments in disinfection supply center,and to provide fundamental data for standardizing treatment procedure.Methods We chose 616 disinfection supply centers in hospitals from 30 provinces,autonomous regions,and municipalities,and sent investigation forms (digital) on treatment of precision surgical instruments,asking head nurses of disinfection supply centers to fill the forms according to real situation.Results Among 616 hospitals receiving treatment of precision surgical instruments,59.74％ had specific cleaning post,69.16％ had specific post for cleaning quality inspection,62.01％ had specific post for assembly and packaging,only 56.33％ had training from manufacturers,48.53％ self-studied instructions provided by manufacturers;18.83％ performed manual cleaning,67.05％ performed manual cleaning followed by ultrasonic cleaning,only 14.12％ performed mechanical cleaning;for method of sterilization,84.10％ used high pressure steam sterilizer,64.61％ used hydrogen peroxide low-temperature plasma sterilization,36.04％ used ethylene oxide sterilization.Conclusion There was a lack of specific posts for precision surgical instruments,especially for cleaning;training for specific posts should be enhanced;cleaning methods were mainly manual and ultrasonic,high pressure steam sterilization was the main method for sterilization.Standardized regulations for cleaning and sterilization are recommended to be made according to different precision surgical instruments.
