Is Tegaderm®️ An Adequate Probe Cover For Ultrasound-Guided Procedures?
We posted a POLL on LinkedIn on whether Tegaderm® is an adequate barrier protection for ultrasound-guided nerve blocks. The poll results indicate that 56% of respondents feel that Tegaderm® is adequate protection.
While many folks think of nerve blocks as a minor intervention with no risk of blood contamination, the reality is different. Here’s just one of many examples in pictures I collected suggesting that Tegaderm® and occlusive dressings are NOT adequate as body fluids/blood barrier protection for ultrasound-guided procedures where the skin is breached with a needle.
In this example, it is clear that:
- The Ultrasound transducer is protected from the blood by Tegaderm but,
- Ultrasound probe cable is contaminated and,
- Leaving the blood-contaminated probe cable on the ultrasound machine contaminated the ultrasound machine as well.
Based on the responses on the LinkedIn page HERE, some of the reasons for using Tegaderm®️ instead of a dedicated probe cover are: Tegaderm®️ is ubiquitously available, it is cheaper than probe covers, and Tegaderm®️ is faster to apply and remove from the ultrasound probe, compared with probe covers that are specifically developed for ultrasound-guided procedures. However, in an abstract we presented at ESRA, we demonstrated that the application and removal of Tegaderm®️ requires the same or more time as application and removal of the full size probe covers.
In this video, we feature “a race” – among two common probe covers (Safersonic and EZCOVER®️) and Tegaderm®️. We were not surprised with the outcome that application of the Tegaderm is not more time-efficient, but also Tegaderm does not protect the ultrasound probe cable from contamination with the patient’s bed, skin, or blood associated with the procedure.
