Intradermal injections: Traditional bevel up versus bevel down

Abstract 

This study used qualitative and quantitative methods to examine differences regarding correct placement of injectate, leaking or bleeding, time to administer injection, and comfort of person administering, and receiving an intradermal injection. Each (N = 98) administered and received two injections. Subjects evaluated their comfort on a Likert scale. After second injection, each reported which was better. Most of the time (82%), a wheal was produced. Leaking or bleeding occurred a fourth of the time. Subjects rated the first injection better (p < 0.05) with no preference regarding technique. Subjects administering injections reported bevel up more comfortable (p < 0.01). Bevel up was significantly faster.
