Starting IVs and drawing blood requires precise finger dexterity and touch sensation. You need to feel the vein, stabilize the site, and guide the needle — all while protecting yourself from needlestick injury and the patient from contamination.
Traditional gloves provide barrier protection but reduce tactile sensitivity. Some clinicians develop techniques to maximize their sense of touch through gloves, but there's a learning curve and some procedures remain challenging.
The Dexterity Challenge
Self-adhering tape provides a different option for finger protection. Thin wraps on fingertips offer some barrier protection while preserving more tactile sensation than gloves. It's not a replacement for gloves when full barrier protection is needed, but it can supplement protection in specific situations.
When Tape Helps
Self-adhering finger tape is useful for protecting cracked skin during procedures, adding grip on difficult venipunctures, protecting fingertips when palpating for vessels, and providing a reminder barrier to avoid touching face or mucous membranes.
It's not appropriate as primary barrier protection for bloodborne pathogen exposure — gloves remain necessary for that purpose.
