LET Gel Effective for Laceration Repair

“Getting stitches” can almost seem like a rite of passage for kids. Skin lacerations requiring sutures account for 8.2% of all visits to hospital emergency departments. While providers seek to reduce patient pain during repair, subcutaneous injection of anesthetic is often uncomfortable for patients, particularly children. (1)

A 2020 study included 59 children between the ages of 3 and 16 with skin lacerations. The study compared the use of lidocaine-epinephrine-tetracaine (LET) gel with EMLA plus mepivacaine infiltration.  LET gel was administered to 37 children; 22 received EMLA plus mepivacaine. “Pretreatment was significantly less painful in LET versus the local anesthetics group,” the study reported. Both groups showed similar efficacy in terms of procedure time, need for secondary infiltration, and infection rate. Pain was measured using the faces pain rating scale (visual analogue scale.) (2)

Beyond use in pediatric cases, a retrospective chart review of 89 patients, with a mean age of 33, found that only 24% of patients with lacerations who received topical LET gel required additional anesthesia. Those who required the additional anesthesia were mostly patients with longer lacerations or in painful locations, such as extremities, trunk, fingers, and toes. (1)

A Cochrane review of 25 randomized controlled trials including 3,278 patients compared LET gel with infiltrated anesthetics and found that topical anesthetics provided effective control, with similar efficacy to infiltrated anesthesia, with no complications. (3)
