Efficacy and feasibility of opioids for burn analgesia: An evidence-based qualitative review of randomized controlled trials.

Opioids are commonly used for burn analgesia, but no comprehensive reviews have been published on such use. We aimed to assess the literature regarding the effectiveness and side effects of opioids both in adult and pediatric burn patients. We conducted a systematic search of the PubMed, Embase, Cochrane, and Web of Science databases. Information on study characteristics, results, and interventions was extracted. The review identified nine studies that satisfied the inclusion criteria. Burn sizes of patients ranged from 1% to 62% of the body. The examined studies showed that dressing or cream containing morphine could potentially decrease pain, use of analgesics, and side effects associated with systemic opioid medications compared with control groups. Oral transmucosal fentanyl citrate (OTFC) was equivalent, or even preferable, to oral morphine, hydromorphone, and oxycodone in provision of analgesia for burn wound care in pediatric patients. Intranasal fentanyl (INF) was equivalent to oral morphine in burn wound care both in adult and pediatric patients. OTFC and INF could be considered as viable non-invasive analgesic alternatives to oral opioids for procedural burn pain. However, the level of evidence still seems quite uncertain because of the limited sample size.
