Cardiology News in 2004 published the results of a study in which one or more antibiotic-resistant pathogens were found in 77% of the ECG leads. Therefore, when using repetitive ECG leads, it is very important to clean and disinfect the lead wires.
For reusable ECG leads, we must disinfect and clean them before and after each use to minimize cross-infection. When cleaning, we must strictly follow the usage requirements. Because inappropriate methods may lead to lead wire can not be used or shorten the lead wire life.
Before cleaning the ECG leads, the reusable ECG leads must be removed from the machine. At the same time, care must be taken during the cleaning process, as there is a possibility that the copper wires of the lead wires may be damaged or pulled out.
For general cleaning, use mild soapy water to lightly wipe wires and cables. Then wait to air dry. But in order to achieve the purpose of disinfection, we must use disinfectant water. Regarding the concentration of disinfectant, we must make proportional dilutions in accordance with the APIC Guidelines for the Selection and Use of Disinfectants (1996). 5.2% household bleach, we can dilute it to between 1:500 and 1:10, then soak a soft, lint-free cloth and wring it dry before wiping.
Since the hardware parts at both ends may be corroded when they come into contact with the disinfectant, which will affect the transmission signal, it is necessary to always pay attention not to let the disinfectant splash into the connector during disinfection. After disinfection, wipe off the disinfectant with a clean damp cloth, dry the ECG leads with a clean cotton cloth, and let it dry for at least 30 minutes (the drying time may vary due to different ambient humidity).
When it comes to sterilization of repetitive leads, we usually think of ETO sterilization. If you want to achieve the ideal sterilization effect, you must use ETO sterilization, but frequent use is not recommended, because ETO sterilization will also shorten the life of the lead wire. Sterilization with ethylene oxide gas (ETO) at a maximum temperature of 50°C/122°F is recommended.
Disinfection and sterilization cannot guarantee 100% removal of pathogens on ECG leads. For the intensive care unit, it is recommended to use disposable ECG leads to reduce cross-infection. Yumai Medical provides compatible disposable lead wires, which are compatible with most electrocardiographs on the market. If you need, you can contact us!
