Abstract
The majority of hospitalized burn patients experience pain, agitation, and delirium. The development of each one of these conditions can also lead to, or worsen, the others. Providers, therefore, need to thoroughly assess the underlying issue to determine the most effective treatment. Multimodal pharmacologic regimens are often used in conjunction with non-pharmacologic strategies to manage pain, agitation, and delirium. This review focuses on the pharmacologic management of these complicated patients in a critical-care setting.

Abstract
Burn injury in children can cause severe and chronic physical and mental sequelae. Opioids are a mainstay in burn pain management but increasing utilization in this country has led to concern for their continued use and potential for dependence. Methadone is a long-acting analgesic that targets the N-methyl-D-aspartate (NMDA) receptor in addition to the mu opioid receptor and has benefit in adult burn patients. However, its use in the pediatric burn population has been less robustly studied. This is a retrospective cohort study at a single Level 1 Burn Center whose primary aim is to compare opioid utilization 36 hours postoperatively between pediatric burn patients who received intraoperative, intravenous methadone and those who did not. Secondary aim was to describe differences in methadone-related complications between the cohorts. There was decreased opioid utilization measured by median morphine equivalents per kilogram (ME/kg) postoperatively in the methadone cohort compared to the control cohort (0.54mg/kg v. 0.77mg/kg, p = 0.18). No adverse events were noted upon chart review. The data suggests methadone use is beneficial in pediatric burn patients, but further prospective studies are warranted on a larger population.

Abstract
The ABA pain guidelines were developed 14 years ago and have not been revised despite evolution in the practice of burn care. A sub-committee of the American Burn Association's Committee on the Organization and Delivery of Burn Care was created to revise the adult pain guidelines. A MEDLINE search of English-language publications from 1968 to 2018 was conducted using the keywords "burn pain," "treatment," and "assessment." Selected references were also used from the greater pain literature. Studies were graded by two members of the committee using Oxford Centre for Evidence-based Medicine-Levels of Evidence. We then met as a group to determine expert consensus on a variety of topics related to treating pain in burn patients. Finally, we assessed gaps in the current knowledge and determined research questions that would aid in providing better recommendations for optimal pain management of the burn patient. The literature search produced 189 papers, 95 were found to be relevant to the assessment and treatment of burn pain. From the greater pain literature 151 references were included, totaling 246 papers being analyzed. Following this literature review, a meeting to establish expert consensus was held and 20 guidelines established in the areas of pain assessment, opioid medications, nonopioid medications, regional anesthesia, and nonpharmacologic treatments. There is increasing research on pain management modalities, but available studies are inadequate to create a true standard of care. We call for more burn specific research into modalities for burn pain control as well as research on multimodal pain control.

Abstract
Abstract
Opioids are the mainstay of pain management after burn injury. The United States currently faces an epidemic of opioid overuse and abuse, while simultaneously experiencing a nationwide shortage of intravenous narcotics. Adjunctive pain management therapies must be sought and utilized to reduce the use of opioids in burn care to prevent the long-term negative effects of these medications and to minimize the dependence on opioids for analgesia. The purpose of this review was to identify literature on adjunctive pain management therapies that have been demonstrated to reduce pain severity or opioid consumption in adult burn patients. Three databases were searched for prospective studies, randomized controlled trials, and systematic reviews that evaluated adjunctive pain management strategies published between 2008 and 2019 in adult burn patients. Forty-six studies were analyzed, including 24 randomized controlled trials, six crossover trials, and 10 systematic reviews. Various adjunctive pain management therapies showed statistically significant reduction in pain severity. Only one randomized controlled trial on music therapy for acute background pain showed a reduction in opioid use. One cohort study on hypnosis demonstrated reduced opioid use compared with historical controls. We recommend the development of individualized analgesic regimens with the incorporation of adjunctive therapies in order to improve burn pain management in the midst of an abuse crisis and concomitant national opioid shortage.

Abstract
Acute pain is a prevalent issue for patients recovering from surgical procedures. Methadone has been recognized as a unique option for treatment of surgical pain due to its multiple mechanisms of analgesia and its potential to decrease tolerance to other opioids. Studies of methadone use in postoperative settings are sparse in part due to safety concerns, such as complex pharmacokinetics, risk of respiratory depression, and association with arrhythmias. In this case study of a 70-year-old male with postsurgical abdominal pain, methadone utilization over a period of 9 days resulted in patient-reported analgesia and aided in de-escalating overall opioid use. More studies are needed to develop guidance on how methadone can be used to relieve pain following surgical procedures.

Abstract
BACKGROUND Methadone is effective for the treatment of chronic pain, but its unique pharmacology requires additional considerations with dosing and monitoring. OBJECTIVE The study objective was to evaluate methadone prescribing for pain and subsequent monitoring. METHODS This retrospective chart review at a single center reviewed patients who received methadone over a two-year period. RESULTS Of the 100 patients, most were noncancer cases (60%) with unspecified pain (50%). The majority of methadone treatments were initiated by medicine service (37%), followed by burn service (27%), and trauma (10%). Forty-two percent of the patients were being followed by the palliative care team, primarily for the medicine patients (80%). Patients on the burn service had significantly higher oral morphine equivalent (χ2 = 10.6, p = 0.01) and longest length of stay (χ2 = 37.9, p = 0.0001). Patients on medicine service were significantly more likely to have an outpatient discharge plan for methadone starts in the hospital (odds ratio = 3.7, confidence interval: 1.4, 9.7). Only 45% of patients had an electrocardiogram (EKG) checked seven days before methadone start and 37% of those have a measured corrected QT (QTc) of greater than 450 milliseconds. Electrolytes (potassium and magnesium) were not consistently checked and, of those that were evaluated, 15-20% were abnormal. There was an average of 2.6 severe or major drug interactions per patient related to methadone, with the most common being related to concomitant sedatives and other medications that prolonged the QTc. CONCLUSIONS Prescribing guidelines for methadone would provide a consistent approach for all practitioners involved in using methadone safely and effectively for chronic pain.

Abstract
BACKGROUND Many factors make methadone an appealing option for treatment of pain in patients seen by palliative care; however, complex drug-related properties and variable patient response complicate appropriate conversion ratios from other opioids to methadone. Currently, there is no consensus regarding one accepted conversion method. OBJECTIVE Current patterns of prescribing for clinicians at a three-hospital academic health system on initial rotation to methadone for the management of pain were compared with a series of consensus recommendations for methadone dose calculation. DESIGN Retrospective chart review of 98 hospital patients. Settings/Participants: Adult subjects hospitalized in an academic medical center between January 1, 2013, and January 1, 2015, who were initiated on oral methadone for pain during the same admission. MEASUREMENTS Final target daily dose of methadone was calculated using End of Life/Palliative Education Resource Center (EPERC) and Friedman conversion methods based on opioids provided in the prior 24 hours. This was then compared with actual dosing as ordered by clinicians and received by the patient. RESULTS Average range of final daily methadone dose for new starts was 18.1 ± 16.7 mg. Final methadone dose as received by two-thirds of patients was below the dosing target calculated by EPERC and Friedman guidelines by an average of 35 mg. In addition, more than 80% of patients' final methadone doses fell below the range recommended by these two methods. No patients received opioid reversal agents during their index hospitalization. CONCLUSIONS These findings may question the best approach to clinical application of EPERC and Friedman methods and call for more research to determine the safest, lowest, and most effective methadone target dosing selection. Final methadone dosing as received by patients compared favorably with a conservative methadone dosing method that recommends starting doses no higher than 30-40 mg per day.

Abstract
BACKGROUND Continuous opioid infusion therapy is commonly utilized in the pediatric intensive care setting to treat pain and facilitate tolerance of invasive therapies. Transitioning to methadone is one common strategy for weaning from continuous opioid infusions, but in practice this transition can be challenging, and many children still experience iatrogenic withdrawal. AIM We reviewed the literature to evaluate the best available evidence to guide methadone therapy in this setting, and to summarize associated adverse events. METHODS We included all studies of methadone used to facilitate weaning from continuous opioid infusions in pediatric critical care patients, including medical, cardiac, and surgical patients, excluding case reports and studies treating neonatal abstinence syndrome, or acute or chronic pain. Medline, Embase, and CINAHL databases from inception to May 2015 were queried; references of included works and conference proceedings were also reviewed. Two authors independently extracted data from each study. Meta-analysis with fixed- and random-effects models was used to pool results of studies when applicable. RESULTS Twelve studies involving 459 patients met criteria for inclusion. A wide variety of methadone dosing and taper strategies were reported. Mean inpatient methadone taper times varied widely, from 4.3 to 26.2 days. Excessive sedation was the most frequently reported adverse event, occurring in up to 16% of patients. Withdrawal occurred in 27% of patients among studies reporting this outcome. In three of three studies in which a new methadone protocol was introduced, a decreased proportion of patients experienced withdrawal (standardized mean difference, SMD = -0.60, 95% CI = -0.998 to -0.195, P = 0.004). CONCLUSION We did not identify sufficient evidence to recommend any particular methadone weaning strategy, or to recommend methadone over other medications or prescribed infusion weaning, for successful weaning of continuous opioid infusions in the pediatric intensive care setting.

Abstract
PURPOSE Methadone is increasingly used as an analgesic or a bridge to weaning other analgesics and sedatives in critically ill patients. This review discusses the pharmacology of methadone, summarizes available evidence for its use in the intensive care unit setting, and makes suggestions for appropriate use and monitoring. MATERIALS/METHODS Articles evaluating the efficacy, safety, and pharmacology of methadone were identified from a PubMed search through June 2015. References from selected articles were reviewed for additional material. Experimental and observational English-language studies that focused on the efficacy, safety, and pharmacology of methadone in critically-ill adults and children were selected. RESULTS Methadone is a synthetic opioid analgesic with potential advantages over other commonly used opioids. Limited evidence from critically ill pediatric, adult, and burn populations suggests that methadone protocols may expedite weaning opiate infusions, decrease the length of mechanical ventilation, and reduce the incidence of negative outcomes such as opiate withdrawal, delirium, and over-sedation. CONCLUSIONS Data from current literature supports a role for methadone analgesia in weaning opiates and potentially reducing the duration of mechanical ventilation in critically ill patients. More studies are needed to confirm these benefits and determine criteria for patient selection.

Abstract
Thermally injured patients experience tremendous pain from the moment of injury to months or years after their discharge from the hospital. Pain is therefore a critical component of proper management of burns. Although the importance of pain is well recognized, it is often undertreated. Acute uncontrolled pain has been shown to increase the incidence of mental health disorders and increase the incidence of suicide after discharge. Long-term poor pain control leads to an increase in the incidence of persistent pain. Most burn centers have used opioids as the mainstay analgesic, but recently, the significant side effects of opioids have led to the implementation of new and combined therapeutics. Pharmacological agents such as gabapentin, clonidine, dexmedetomidine, and ketamine have all been suggested as adjuncts to opioids in the treatment of burn pain. Nonpharmacological therapies such as hypnosis, virtual reality devices, and behavioral therapy are also essential adjuncts to current medications. This review aims at identifying the currently available pharmacological and nonpharmacological options for optimal pain management in the adult burn population.
