Destroying the Dogma
Lidocaine with epinephrine can be used on the fingers, toes, and the nose and down below.
Advising parents to put antibiotic ointment on absorbable sutures is okay. It will not weaken the strength of the suture.
Remember to always calculate the maximum dose of lidocaine that can be given, especially for kids
3mg/kg = Lidocaine without epinephrine max dose
7mg/kg = Lidocaine with epinephrine max dose
SHORTCUT FOR MAX mLs
Max mLs = max Lido/Epi mg/kg X (weight in kg/10) X (1/concentration of lidocaine)
Let's Practice! Calculate the maximum mLs of 1% lidocaine with epineprine for a 20kg patient
7mg/kg (max dose of Lido/Epi) X 20kg/10 X 1 (concentration of Lido/Epi) =
Most Important Part of Wound Prep?
Irrigate, irrigate, oh and remember to irrigate. You can’t clean too much!
Don't Fear the Deep...
Deep sutures are your friend. Remember- this is the strength layer. The wound should look almost closed after placing deep sutures. If you think it might need a deep, it needs a deep. Too much tension on the superficial sutures leads to worse looking scars in the future!! For a quick review, check out the video below!
Keep It Simple!
For nearly all situations in the emergency department, simple interrupted sutures (video below) are the only sutures you will need to close the superficial layer.

Braids for Hair, Not for Sutures
Although stronger, braided sutures have a higher risk of infection. The braids are a nidus of seeding bacteria. When closing wounds in the ED, try to avoid them, especially with a dirty wound.
Choose the Right Suture for the Job
It's Okay to Glue
Dermabond is an appropriate alternative for holding the nail or aluminum in place after a nail bed repair instead of suturing it in place. Be sure that the the nail or aluminum is splinting the eponychail fold to allow the new nail to grow properly.

Can't Miss Exam Findings in Hand Trauma
If you see either of the below findings on the physical exam, the next step should be to call the hand surgeon.
Scissor/overlapping fingers when making a fist
Fingers are crossed or shortened at neutral position
A True Emergency: Flexor Tenoxynovitis
A word about flexor tenosynovitis… though rare in children, missing this diagnosis can mean big problems for that finger later on! It is a true surgical emergency!
Mechanism (penetrating trauma to tendon sheath) + pain on passive extension = calling the experts to evaluate.
