Why should you let the alcohol dry before giving injection in intradermal location?
- Pain reduction: Alcohol can cause a stinging sensation when it comes in contact with the skin. Allowing the alcohol to dry before the injection can help minimize this discomfort.
- Evaporation: Alcohol evaporates quickly, so waiting a few seconds after applying it to the skin ensures that it has completely evaporated. This helps to reduce the risk of introducing any alcohol into the injection site, which could cause irritation or pain.
- Accuracy: When the skin is wet with alcohol, it can be difficult to accurately assess the location for the injection. Allowing the alcohol to dry helps ensure that the injection is given at the correct depth.
- Infection prevention: Alcohol has antiseptic properties that help to kill bacteria on the skin. Allowing the alcohol to dry ensures that the area is fully disinfected before the injection, reducing the risk of infection.
In general, it is considered best practice to wait at least 10-15 seconds after applying alcohol to the skin before giving an intradermal injection. This helps ensure that the alcohol has evaporated and that the skin is dry, reducing discomfort, ensuring accuracy, and preventing infection.
