Information
The monitoring frequency of glutaraldehyde concentration in use shall refer to the product manual and be determined according to the actual use.
 
In general, when new medical devices are put into use every day, monitor before putting into the device every day to master the change of concentration, and stop using when the concentration is lower than the required concentration; when not new devices are put into use every day, only monitor before putting into the device.
 
As for the monitoring frequency of disinfectants in use, there are some special cases that need to be treated differently. According to the technical specification for cleaning and disinfection of flexible endoscopes in China, "a certain concentration shall be measured after the preparation of disinfectants or disinfectants for repeated use, and monitoring shall be conducted before each use; after the number of disinfected endoscopes reaches half of the specified number, measurement shall be conducted before the disinfection of each endoscope. ”Because some disinfectants (not especially glutaraldehyde) product instructions not only specify the use days, but also specify the use times (i.e. the number of disinfection endoscopes). For example, a product manual stipulates that the disinfectant can be used for 14 days continuously after being prepared, and at the same time, the maximum number of disinfected endoscopes is no more than 25. As the drying treatment before disinfection is impossible to completely remove the residual water, the residual water of each endoscope will continuously dilute the disinfectant. When the disinfection reaches half of the specified number of 25 endoscopes, the probability of unqualified concentration of the disinfectant increases greatly. Therefore, it is required that "after the number of disinfection endoscopes reaches half of the specified number in the manual, the concentration measurement shall be carried out before disinfection of each endoscope "Ding".
 
According to the CDC guidelines for disinfection and sterilization in medical institutions, the frequency of monitoring depends on the frequency of use. Daily use, monitoring before use; not daily use, monitoring before use. When used 30 times a day, monitor every 10 times.
 
In addition, it should be noted that the glutaraldehyde concentration detection indicator card must be used within the validity period, and the chemicals on the indicator card will deteriorate over time. When the indicator card is enabled, the opening time and effective use time after opening (such as 120 days) shall be indicated.
