- Classic dogma teaching that epinephrine should not be used in the fingers, nose, penis, and toes when performing local anesthesia due to concerns for ischemia is wrong
- This has been well documented in multiple literature reviews
- A prospective, randomized double-blind study compared lidocaine vs lidocaine with epinephrine for finger injuries and the use of epinephrine was associated with less bleeding and better anesthesia
Editor’s note: in the lidocaine without epinephrine group, 5 (not 7) needed additional dosing of local anesthesia. The groups were also split 29 for lidocaine alone and 31 for lidocaine with epinephrine but we’re in a pandemic so who is noticing anyways
