Psychiatric Risk Factors and Burn Severity in Self-immolation.

Self-immolation, a form of self-harm involving setting oneself on fire, is associated with high mortality, morbidity, and healthcare burden. This study aimed to characterize potential clinical correlates and predisposing factors for self-immolation based on burn severity using TBSA percentage scoring. Additional objectives included identifying motivational elements, associated risk factors, and clinical characteristics to optimize patient care and reduce future self-immolation incidents. A retrospective review of admissions to the Arizona Burn Center from July 2015 to August 2022 identified 103 self-immolation patients for the study. Burn severity was categorized as mild to moderate (TBSA < 20%) or severe (TBSA ≥ 20%) based on TBSA. This study population had a mortality rate of 21%. Positive urine drug screens were found in 44% of subjects, and 63% having chronic substance use, with methamphetamine (37%) and alcohol (30%), being the most prevalent. Underlying psychiatric illnesses were present in 83% of patients. Suicidal intent strongly predicted severe burns (P < .001) among the 68 severe burn cases identified. In conclusion, this study emphasizes that the presence of suicidal intent among self-immolation patients significantly correlates with burn severity. These findings highlight the importance of involving psychiatric services early in patient care to improve outcomes and reduce the recurrence of self-immolation acts.

Measuring the burden of pediatric burn injury for parents and caregivers: informed burn center staff can help to lighten the load.

This study sought to identify which commonly experienced burn-related issues parents/caregivers of burn-injured youth deemed most stressful, difficult, and disruptive during their child's initial acute burn care hospitalization, and following the child's discharge. Parents completed an 11-item survey, asking them to rate the difficulty of items regarding their child's burn injury. The scale was created by burn doctors, nurses, and psychologists with an average of 10.5 (SD ± 4.8) years of experience. Items selected were among common parental problems reported in the burn literature. Respondents included 69 parents/caregivers of previously hospitalized, burn-injured youth. The majority were mothers, n = 51 (74%), and n = 34 (49%) were Caucasian. The most represented age group was 37 to 45 years, n = 31 (45%). Children were on average, 6.04 years out from their initial injury. All parents reported their child's pain as the most difficult part of the injury, n = 69 (100%). The second most common issue was the child's first hospital stay. The other two items found to be "very hard" or "pretty hard" were the time spent away from their other children, and feelings of hopelessness in being unable to fix everything for their child. In this study, key parental problems occurred during the child's initial hospitalization. Burn staff cannot alleviate all problems, however, staff education regarding distressing problems faced by parents, as well as possible solutions, can be made available.

A multicenter study of preventable contact burns from glass fronted gas fireplaces.

Glass fronted gas fireplaces (GFGFs) have exterior surfaces that can reach extremely high temperatures. Burn injuries from contact with the glass front can be severe with long-term sequelae. The Consumer Product Safety Commission reported that these injuries are uncommon, whereas single-center studies indicate a much higher frequency. The purpose of this multi-institutional study was to determine the magnitude and severity of GFGF injuries in North America. Seventeen burn centers elected to participate in this retrospective chart review. Chart review identified 402 children ≤10 years of age who sustained contact burns from contact with GFGF, who were seen or admitted to the study hospitals from January 2006 to December 2010. Demographic, burn, treatment, and financial data were collected. The mean age of the study group was 16.8 ± 13.3 months. The majority suffered burns to their hands (396, 98.5%), with burns to the face being the second, much less common site (14, 3.5%). Two hundred and sixty-nine required rehabilitation therapy (66.9%). The number of GFGF injuries reported was 20 times greater than the approximately 30 injuries estimated by the Consumer Product Safety Commission's 10-year review. For the affected children, these injuries are painful, often costly and occasionally can lead to long-term sequelae. Given that less than a quarter of burn centers contributed data, the injury numbers reported herein support a need for broader safety guidelines for gas fireplaces in order to have a significant impact on future injuries.

Results of a prospective randomized controlled trial of early ambulation for patients with lower extremity autografts.

It is common practice to keep those patients with lower extremity autografts immobile until post-operative day (POD) 5. There is however inherent risks associated with even short periods of immobility. As of now there are no randomized controlled trials looking at early ambulation of patients with lower extremity autografts in the burn community.The objective of this study was to show that patients who begin ambulation within 24 hours of lower extremity autografting will have no increased risk of graft failure than those patients who remain immobile until POD 5. Thirty-one subjects who received autografts to the lower extremity were randomized after surgery into either the early ambulation group (EAG;17 subjects) or the standard treatment group (STG;14 subjects). Those subjects randomized to the EAG began ambulating with physical therapy on POD 1. Subjects in the STG maintained bed rest until POD 5. There was no difference in the number of patients with graft loss in either the EAG or STG on POD 5, and during any of the follow-up visits. No subjects required regrafting. There was a significant difference in the mean minutes of ambulation, with the EAG ambulating longer than the STG (EAG 23.4 minutes [SD 12.03], STG 14.1 [SD 9.00], P=.0235) on POD 5. Burn patients with lower extremity autografts can safely ambulate on POD 1 without fear of graft failure compared with those patients that remain on bed rest for 5 days.

The blue man: burn from muriatic acid combined with chlorinated paint in an adult pool construction worker.

Muriatic acid (hydrochloric acid), a common cleaning and resurfacing agent for concrete pools, can cause significant burn injuries. When coating a pool with chlorinated rubber-based paint, the pool surface is initially cleansed using 31.45% muriatic acid. Here we report a 50-year-old Hispanic male pool worker who, during the process of a pool resurfacing, experienced significant contact exposure to a combination of muriatic acid and blue chlorinated rubber-based paint. Confounding the clinical situation was the inability to efficiently remove the chemical secondary to the rubber-based nature of the paint. Additionally, vigorous attempts were made to remove the rubber paint using a variety of agents, including bacitracin, chlorhexidine soap, GOOP adhesive, and Johnson's baby oil. Resultant injuries were devastating fourth-degree burns requiring an immediate operative excision and amputation. Despite aggressive operative intervention and resuscitation, he continued to have severe metabolic derangements and ultimately succumbed to his injuries. We present our attempts at debridement and the system in place to manage patients with complex chemical burns.

Tracheobronchial protease inhibitors, body surface area burns, and mortality in smoke inhalation.

The objective of this study was to assess tracheobronchial protease inhibitor concentrations longitudinally and determine whether initial concentrations predict subsequent lung injury and mortality in intubated burn victims. Tracheobronchial suction fluid was collected every 2 hours for 36 hours. Alpha-1-antitrypsin (AAT), secretory leukocyte peptidase inhibitor (SLPI), alpha-2-macroglobulin (A2M), and cell and differential counts were assayed. Partial pressure of oxygen in arterial blood/fraction of inspired oxygen (PaO2/FIO2) and peak airway pressure (PAP) were recorded for 72 hours. Standard statistics were used to evaluate cross-sectional relationships; random coefficient (mixed) models were used to evaluate temporal trends in marker concentrations and relation to clinical outcomes. Among 29 patients, 24 (83%) developed hypoxemia (PaO2/FIO2 <200); six died within 2 weeks. When adjusted for gender, age, %TBSA burn, and positive end-expiratory pressure setting, A2M (P = .007) and neutrophils (P = .032) increased linearly during 36 hours, and SLPI decreased (P = .038). Initial SLPI concentration was a negative predictor of maximum PAP (P = .009). None of the markers predicted longitudinal change in PaO2/FIO2. Mean levels of AAT and A2M in initial samples were significantly lower in patients with >35% TBSA burn (P = .010 and .033, respectively), when compared with patients with less severe burns. However, patients with increased A2M in combination with >35% TBSA burn had a 6-fold (95% CI: 1.8-20) increased relative risk of death. Tracheobronchial AAT and A2M levels were significantly lower in patients with more severe burns and increased over time. Initial SLPI levels predicted subsequent PAP. Increased early A2M in combination with extensive burn predicted early mortality.

Tracheobronchial markers of lung injury in smoke inhalation victims.

Although smoke inhalation injury victims frequently develop severe hypoxemia and are at increased risk of acute respiratory distress syndrome (ARDS), no early prognostic tests are currently available. The objectives were to determine early longitudinal changes in tracheobronchial fluid inflammatory markers and assess the value of initial concentrations as predictors of subsequent lung injury. Partial pressure of arterial oxygen (Pao2) and the fraction of inspired oxygen (Fio2) were recorded approximately every 6 hours from intubated smoke inhalation victims admitted to a regional burn center. Tracheobronchial suction fluid was collected every 2 hours and assayed for interleukins (IL-1beta, -8, and -10), tumor necrosis factor-alpha, transforming growth factor-beta1, soluble Fas ligand (sFasL), and complement factor 5a. Temporal trends in marker concentrations during 36 hours and the relations between initial concentrations and lowest Pao2/Fio2 or ARDS within 72 hours were assessed using random coefficients modeling and cross-sectional analysis. In 21 subjects with tracheobronchial samples collected within 6.5 hours of intubation, 14 (66.7%) developed acute hypoxemia (Pao2/Fio2 < or =200) within 72 hours of exposure and nine (42.9%) developed ARDS, as defined by the American-European consensus conference on ARDS. IL-8 increased sharply in the first 6.5 hours postexposure (P < .001), and IL-1beta in the first 6.1 hours (P < .001). No significant temporal trends in IL-10, tumor necrosis factor-alpha, transforming growth factor-beta1, sFasL, or complement factor 5a were found. Only initial IL-8 was associated with increased Pao2/Fio2 (P = .013) and with a minimum Pao2/Fio2 >200 (P = .042) during 72 hours. In smoke inhalation victims, tracheobronchial IL-1beta and IL-8 increase rapidly and high initial IL-8 may predict improved oxygenation.
