RESUMEN
Lacerations are common injuries managed by emergency department practitioners and are mostly witnessed in children. These lacerations usually require wound closure, which may result in one of the most unpleasant and painful childhood experiences. The pain can be minimized through topical anesthesia, such as a combination of lidocaine, epinephrine, and tetracaine (LET) and a eutectic mixture of local anesthetics (EMLA). The current study was carried out to demonstrate the efficacy of EMLA and LET in pediatric wound management. A thorough literature search was carried out without any time limitation on five electronic databases, including PubMed, Medline, Web of Science, Embase, and Google Scholar. Relevant studies from these databases and their references were scoured for additional studies. Study quality appraisal and data analysis were conducted using Review Manager software (RevMan 5.4.1). The literature search yielded 1651 articles of which only eight were eligible for inclusion in the present study. A meta-analysis of results from 3 studies showed that LET had a significant pain reduction than the control interventions (SMD: -0.46; 95% CI: -0.69, -0.23: p<0.0001). However, the pooled effect size of data from 3 studies showed EMLA had an insignificant difference with the control interventions (SMD: -0.79; 95% CI: -1.82, -0.24: p = 0.13). Similarly, no significant difference in the number of adverse reactions was reported in either EMLA (OR: 2.31; 95% CI: 0.67, 7.93; p = 0.18) or LET (OR: 0.99; 95% CI: 0.15, 6.50; p = 0.99) Our study suggests that the topical application of EMLA and LET effectively offers pain-free wound management among pediatric patients. However, the interventions are subject to adverse reactions that should be considered when managing the wounds.
