Derangements in pharmacokinetics and pharmacodynamics (PK/PD) of burn patients are poorly understood and lacking consistent data. This leads to an absence of consensus regarding pharmacologic management of burn patients, complicating their care. In order to effectively manage burn critical illness, knowledge of pharmacologic parameters and their changes is necessary.

Background: Frostbite is an insidious disease that normally affects people of cold climates. Winter Storm Uri, which occurred from February 12-20, 2021, created unique metrological conditions for Texas. It caused prolonged sub-freezing temperatures and led to rolling blackouts, affecting 2.

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.

Critical illness caused by burn and sepsis is associated with pathophysiologic changes that may result in the alteration of pharmacokinetics (PK) of antibiotics. However, it is unclear if one mechanism of critical illness alters PK more significantly than another. We developed a population PK model for piperacillin and tazobactam (pip-tazo) using data from 19 critically ill patients (14 non-burn trauma and 5 burn) treated in the Military Health System.

What Is Known And Objective: Timely and appropriate dosing of antibiotics is essential for the treatment of bacterial sepsis. Critically ill patients treated with continuous kidney replacement therapy (CKRT) often have physiologic derangements that affect pharmacokinetics (PK) of antibiotics and dosing may be challenging. We sought to aggregate previously published piperacillin and tazobactam (pip-tazo) pharmacokinetic data in critically ill patients undergoing CKRT to better understand pharmacokinetics of pip-tazo in this population and better inform dosing.

Introduction: Severe burn injury involves widespread skin and tissue damage leading to systemic inflammation, hypermetabolism and multi-organ failure. The hypermetabolic phase of burn injury has been associated with increased systemic antibiotic clearance; however, critical illness in the absence of burn may also induce similar physiologic changes. Continuous renal replacement therapy (CRRT) is often implemented in critically ill patients and may also affect antibiotic clearance.

Background: Following severe burn injury, patients undergo profound metabolic changes, including insulin resistance and hyperglycemia. Hyperglycemia has been linked to impaired wound healing, increased risk of skin graft loss, increased muscle catabolism, increased infections, and mortality. Sitagliptin is a dipeptidyl peptidase-4 (DPP-4) inhibitor that improves glycemic control by slowing the inactivation of incretin hormones, increasing insulin synthesis and release from pancreatic beta cells and lowering glucagon secretion from pancreatic alpha cells.

: Hydroxocobalamin is frequently administered to patients after injures sustained during structure fires or fires in enclosed spaces, prior to confirming inhalation injury with bronchoscopy. Hydroxocobalamin is generally considered safe. However, over the last several years, the safety of hydroxocobalamin has been called into question by case reports of crystalline nephropathy and interference with renal replacement therapies.

Infection is common after burn injury and accounts for the most frequent complications of burn injury. This review describes the effects of burn injury on pharmacokinetics, focusing on the impact of these changes on antimicrobial therapy. The published literature on pharmacokinetics and pharmacodynamics in burn injury of antibiotic use was reviewed.

Patients who suffer hand burns are at a high contracture risk, partly due to numerous cutaneous functional units, or contracture risk areas, located within the hand. Patients who undergo split-thickness skin grafting are often immobilized postoperatively for graft protection. Recent practice at our burn center includes an early range of motion (EROM) following hand grafting to limit unnecessary immobilization.

Animal-assisted interventions have been implemented in both inpatient and outpatient settings and have demonstrated positive outcomes on patients and hospital staff. Animal-assisted interventions have not been previously reported in any burn center. A therapy dog program was established at our burn center with the intent of improving duration and quality of rehabilitation sessions and physical therapy.

Background: The purpose of this study was to examine risk factors for mortality in burned patients with inhalation injury (II). We further sought to compare a cohort of burned military service members to civilian patients with II.

Methods: We identified patients treated at our burn center over a 10-year period.

Nutrition is an essential component of the healing and recovery process after severe burn injury. For many burn patients, nutrition support is necessary to meet nutrition goals. The ratio of carbohydrates and fat is particularly important for burn patients, as an essential fatty acid deficiency can contribute to poor wound healing.

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.

Objective: The current conflicts in Iraq and Afghanistan resulted in an increased incidence of burn injury in the military population. We sought to compare the characteristics and outcomes of this population to a civilian cohort cared for at the same burn center over the same time-period.

Methods: A retrospective review was performed to examine differences in the demographics, etiology, mortality, and functional status over a 12-year period.

Maintaining body temperature is a unique challenge with burn care. We sought to describe core temperature goals in the operating room (OR) and the methods used to achieve and maintain these goals, along with current methods of warming in the intensive care unit (ICU), the perception of effect of increased ambient temperature on work performance, and concerns with contamination of sterile fields due to increased ambient temperature. A 24 question survey was disseminated to burn centers in the United States and Canada.

Background: Ketamine may be used to manage pain and agitation that is refractory to what are usually considered traditional agents such as fentanyl, propofol, benzodiazepines, and dexmedetomidine; however, literature describing the use of ketamine continuous infusions for this purpose in critically ill trauma patients is limited.

Objectives: The primary objective of this study was to determine the impact of the initiation of a ketamine continuous infusion on sedative and analgesic use in critically ill trauma patients. Secondary objectives were to identify the patient population in which ketamine was initiated, assess the proportion of time patients were at their goal level of sedation, and determine the dosing patterns of adjunctive sedative agents.

Objective: Fungal infections remain a major cause of mortality in the burned population. Mafenide acetate/amphotericin B solution (SMAT) has been used topically for prophylaxis and treatment of these infections. Current manufacturer guidelines only guarantee the stability of mafenide solution and amphotericin B at room temperature.
