ABSTRACTIntroduction: Multimodal analgesia associated to adjuvants like intravenous lidocaine is the current recommendation for postoperative pain in burned patients. The aim was to compare the intensity of postoperative pain in burned patients treated with multimodal analgesia with and without intravenous lidocaine. Material and methods: An observational study was performed in postoperative pain through the Visual Analogic Scale registered in records of burned patients to compare three schemes of multimodal analgesia: Non-lidocaine group, Intraoperative lidocaine group and Postoperative lidocaine group. Results: When comparing Intraoperative lidocaine group versus the Postoperative lidocaine group, the first one found lower pain intensity at all times of the records, but the difference was statistically significant in background pain (p = 0.01), at 24 hours (p = 0.002), 32 hours (p = 0.03), 40 hours (p = 0.002), 48 hours (p = 0.003), 56 hours (p = 0.002), 72 hours (p = 0.03), at the first (p = 0.02), second (p = 0.002) and the third postoperative day (p = 0.01). Conclusions: Burned patients treated with intravenous lidocaine infusion during surgery at dose of 2 mg/kg ideal body weight/hour as a component of a multimodal analgesia scheme presented lower intensity of postoperative pain.
