Question: Does eMLA cream prior to digital nerve block for ingrown nail surgery reduce pain at injection of anesthetic solution?
Answer: We found no clinical benefit in using EMLA during digital nerve block. Although the digital nerves are not deeply located in the small subcutaneous space of the digit, topical anesthesia may not reach them. Moreover, swelling due to injection of the anesthetic product in this small space may also amplify the sensation of pain.
Output:
no
