How to Disinfect a Stethoscope from COVID-19
Now more than ever, sterilising your stethoscope between patients is a step you cannot miss. Stethoscopes come into direct contact with every patient you examine, and are very likely to be the source of patient-to-patient COVID-19 infection if not disinfected after each contact.
So how do you clean your stethoscope to prevent COVID-19 transmission? Which sterilizing agents definitely kill COVID-19? Firstly, here are a few ways you should certainly NOT clean or sterilize a stethoscope:
- DO NOT IMMERSE OR SOAK YOUR STETHOSCOPE IN ANY LIQUID
Liquid can enter the tubes and chestpieces and affect its performance both in the short and longer term. Once liquid enters the stethoscope it can also be difficult to dry and promote further bacterial growth.
- DO NOT USE HAND SANITIZER GEL
Many hand gel sanitizers contain additives or solvents that can damage parts of the stethoscope and accelerate degradation.
- DO NOT USE HEAT STERILIZATION METHODS
This includes autoclave sterilizers and any boiling sterilization methods. Autoclave machines subject equipment to pressurised steam at 121 °C (250 °F) and several parts of the stethoscope can degrade when exposed to such high temperatures for prolonged periods.
- DO NOT USE OIL BASED CLEANING SOLVENTS
Oil-based cleaning solvents slowly degrade stethoscope tubing, especially stethoscope tubes made from natural rubber latex. Oils released from human skin can likewise affect the integrity of stethoscope tubing, so wearning your stethoscope over a collar rather than on direct skin can prolong its life and prevent discoloring.
Now that we know what not to do, what can you actually use to sterilise a stethoscope without causing any damage?
