Early excision and autografting are standard care for deeper burns. However, donor sites are a source of significant morbidity. To address this, the ReCell

Autologous Cell Harvesting Device ...(ReCell) was designed for use at the point-of-care to prepare a noncultured, autologous skin cell suspension (ASCS) capable of epidermal regeneration using minimal donor skin. A prospective study was conducted to evaluate the clinical performance of ReCell vs meshed split-thickness skin grafts (STSG, Control) for the treatment of deep partial-thickness burns. Effectiveness measures were assessed to 1 year for both ASCS and Control treatment sites and donor sites, including the incidence of healing, scarring, and pain. At 4 weeks, 98% of the ASCS-treated sites were healed compared with 100% of the Controls. Pain and assessments of scarring at the treatment sites were reported to be similar between groups. Significant differences were observed between ReCell and Control donor sites. The mean ReCell donor area was approximately 40 times smaller than that of the Control (
P
< .0001), and after 1 week, significantly more ReCell donor sites were healed than Controls (
P
= .04). Over the first 16 weeks, patients reported significantly less pain at the ReCell donor sites compared with Controls (
P
≤ .05 at each time point). Long-term patients reported higher satisfaction with ReCell donor site outcomes compared with the Controls. This study provides evidence that the treatment of deep partial-thickness burns with ASCS results in comparable healing, with significantly reduced donor site size and pain and improved appearance relative to STSG.
Traumatic insults, infection, and surgical procedures can leave skin defects that are not amenable to primary closure. Split-thickness skin grafting (STSG) is frequently used to achieve closure of ...these wounds. Although effective, STSG can be associated with donor site morbidity, compounding the burden of illness in patients undergoing soft tissue reconstruction procedures. With an expansion ratio of 1:80, autologous skin cell suspension (ASCS) has been demonstrated to significantly decrease donor skin requirements compared with traditional STSG in burn injuries. We hypothesized that the clinical performance of ASCS would be similar for soft tissue reconstruction of nonburn wounds.
A multicenter, within-patient, evaluator-blinded, randomized-controlled trial was conducted of 65 patients with acute, nonthermal, full-thickness skin defects requiring autografting. For each patient, two treatment areas were randomly assigned to concurrently receive a predefined standard-of-care meshed STSG (control) or ASCS + more widely meshed STSG (ASCS+STSG). Coprimary endpoints were noninferiority of ASCS+STSG for complete treatment area closure by Week 8, and superiority for relative reduction in donor skin area.
At 8 weeks, complete closure was observed for 58% of control areas compared with 65% of ASCS+STSG areas (p = 0.005), establishing noninferiority of ASCS+STSG. On average, 27.4% less donor skin was required with ASCS+ STSG, establishing superiority over control (p < 0.001). Clinical healing (≥95% reepithelialization) was achieved in 87% and 85% of Control and ASCS+STSG areas, respectively, at 8 weeks. The treatment approaches had similar long-term scarring outcomes and safety profiles, with no unanticipated events and no serious ASCS device-related events.
ASCS+STSG represents a clinically effective and safe solution to reduce the amount of skin required to achieve definitive closure of full-thickness defects without compromising healing, scarring, or safety outcomes. This can lead to reduced donor site morbidity and potentially decreased cost associated with patient care.Clincaltrials.gov identifier: NCT04091672.

ABRUPT was a prospective, noninterventional, observational study of resuscitation practices at 21 burn centers. The primary goal was to examine burn resuscitation with albumin or crystalloids alone, ...to design a future prospective randomized trial.
No modern prospective study has determined whether to use colloids or crystalloids for acute burn resuscitation.
Patients ≥18 years with burns ≥ 20% total body surface area (TBSA) had hourly documentation of resuscitation parameters for 48 hours. Patients received either crystalloids alone or had albumin supplemented to crystalloid based on center protocols.
Of 379 enrollees, two-thirds (253) were resuscitated with albumin and one-third (126) were resuscitated with crystalloid alone. Albumin patients received more total fluid than Crystalloid patients (5.2 ± 2.3 vs 3.7 ± 1.7 mL/kg/% TBSA burn/24 hours), but patients in the Albumin Group were older, had larger burns, higher admission Sequential Organ Failure Assessment (SOFA) scores, and more inhalation injury. Albumin lowered the in-to-out (I/O) ratio and was started ≤12 hours in patients with the highest initial fluid requirements, given >12 hours with intermediate requirements, and avoided in patients who responded to crystalloid alone.
Albumin use is associated with older age, larger and deeper burns, and more severe organ dysfunction at presentation. Albumin supplementation is started when initial crystalloid rates are above expected targets and improves the I/O ratio. The fluid received in the first 24 hours was at or above the Parkland Formula estimate.
The objective of this multicenter observational study was to evaluate resuscitation volumes and outcomes of patients who underwent fluid resuscitation utilizing the Burn Navigator (BN), a ...resuscitation clinical decision support tool. Two analyses were performed: examination of the first 24 hours of resuscitation and the first 24 hours postburn regardless of when the resuscitation began, to account for patients who presented in a delayed fashion. Patients were classified as having followed the BN (FBN) if all hourly fluid rates were within ±20 ml of BN recommendations for that hour at least 83% of the time; otherwise, they were classified as not having followed BN (NFBN). Analysis of resuscitation volumes for FBN patients in the first 24 hours resulted in average volumes for primary crystalloid and total fluids administered of 4.07 ± 1.76 ml/kg/TBSA (151.48 ± 77.46 ml/kg) and 4.68 ± 2.06 ml/kg/TBSA (175.01 ± 92.22 ml/kg), respectively. Patients who presented in a delayed fashion revealed average volumes for primary and total fluids of 5.28 ± 2.54 ml/kg/TBSA (201.11 ± 106.53 ml/kg) and 6.35 ± 2.95 ml/kg/TBSA (244.08 ± 133.5 ml/kg), respectively. There was a significant decrease in the incidence of burn shock in the FBN group (P < .05). This study shows that the BN provides comparable resuscitation volumes of primary crystalloid fluid to the Parkland formula, recommends total fluid infusion less than the Ivy index, and was associated with a decreased incidence of burn shock. Early initiation of the BN device resulted in lower overall fluid volumes.
•Demographic data and burn specific data for Native American and non-Native American burn patients were collected and reviewed.•Significant differences in a variety of data points between the two ...groups were identified reflecting health care disparity.•The disparities identified were most likely related to socioeconomic factors between the two groups.
Native Americans (NAs) have worse healthcare outcomes over some measures than non-Native Americans (non-NAs) (i.e., lower life expectancy, higher heart disease and psychiatric disease rates). Little data exists to show if there are differences in the hospital course of burned NAs versus non-NA patients. The purpose of this study is to analyze the epidemiology, clinical course, and outcomes of NA burn injury in Arizona.
We conducted a retrospective database review of all burn center burn admissions from 2000 to 2015. This initial dataset of 12,724 patients included all initial presentations for burns, non-burns, and readmissions. From this database, we extracted all patients who were new admissions for burn injuries only. This resulted in 10,521 patients of which 9555 patients were non-NA patients and 966 were NA patients. The burn center collects sixty-eight data points to populate our burn database; of these data points, we reviewed twenty-nine to assess if differences existed.
Statistically significant differences exist between the two groups with regard to age, geographic locality at time of burn, circumstances surrounding the injury, etiology of the injury, method of transport to the regional burn center, total length of stay, Injury Severity Score on admission, total percent total body surface area burned, month of year of burn injury, hospital charges, payor source for medical costs, and the final disposition. NA burn patients were more often burned at recreational than occupational sites and while participating in non-work related activities. Burn etiologies in NA patients were more frequently due to contact and flame. NA burn patients tended to have greater hospital length of stays and greater charges, and were less likely to be discharged home.
Our data demonstrate that NAs have a different experience with the healthcare system than non-NAs after a burn injury. The majority of these issues revolve around socioeconomic differences between the two groups.
This article summarizes research conducted over the last decade in the field of inhalation injury in thermally injured patients. This includes brief summaries of the findings of the 2006 State of the ...Science meeting with regard to inhalation injury, and of the subsequent 2007 Inhalation Injury Consensus Conference. The reviewed studies are categorized in to five general areas: diagnosis and grading; mechanical ventilation; systemic and inhalation therapy; mechanistic alterations; and outcomes.
The goal of burn resuscitation is to provide the optimal amount of fluid necessary to maintain end-organ perfusion and prevent burn shock. The objective of this analysis was to examine how the Burn ...Navigator (BN), a clinical decision support tool in burn resuscitation, was utilized across five major burn centers in the United States, using an observational trial of 300 adult patients. Subject demographics, burn characteristics, fluid volumes, urine output, and resuscitation-related complications were examined. Two hundred eighty-five patients were eligible for analysis. There was no difference among the centers on mean age (45.5 ± 16.8 years), body mass index (29.2 ± 6.9), median injury severity score (18 interquartile range: 9-25), or total body surface area (TBSA) (34 25.8-47). Primary crystalloid infusion volumes at 24 h differed significantly in ml/kg/TBSA (range: 3.1 ± 1.2 to 4.5 ± 1.7). Total fluids, including colloid, drip medications, and enteral fluids, differed among centers in both ml/kg (range: 132.5 ± 61.4 to 201.9 ± 109.9) and ml/kg/TBSA (3.5 ± 1.0 to 5.3 ± 2.0) at 24 h. Post-hoc adjustment using pairwise comparisons resulted in a loss of significance between most of the sites. There was a total of 156 resuscitation-related complications in 92 patients. Experienced burn centers using the BN successfully titrated resuscitation to adhere to 24 h goals. With fluid volumes near the Parkland formula prediction and a low prevalence of complications, the device can be utilized effectively in experienced centers. Further study should examine device utility in other facilities and on the battlefield.
Abstract
Mortality associated with burn injuries is declining with improved critical care. However, patients admitted with concurrent substance use have increased risk of complications and poor ...outcomes. The impact of alcohol and methamphetamine use on acute burn resuscitation has been described in single-center studies; however, has not been studied since implementation of computerized decision support for resuscitation. Patients were evaluated based presence of alcohol, with a minimum blood alcohol level of 0.10, or positive methamphetamines on urine drug screen. Fluid volumes and urine output were examined over 48 hours. A total of 296 patients were analyzed. 37 (12.5%) were positive for methamphetamine use, 50 (16.9%) were positive for alcohol use, and 209 (70.1%) with negative for both. Patients positive for methamphetamine received a mean of 5.30 ± 2.63 cc/kg/TBSA, patients positive for alcohol received a mean of 5.41 ± 2.49 cc/kg/TBSA, and patients with neither received a mean of 4.33 ± 1.79 cc/kg/TBSA. Patients with methamphetamine or alcohol use had significantly higher fluid requirements. In the first 6 hours patients with alcohol use had significantly higher urinary output (UO) in comparison to patients with methamphetamine use which had similar output to patients negative for both substances. This study demonstrated that patients with alcohol and methamphetamine use had statistically significantly greater fluid resuscitation requirements compared to patients without. The effects of alcohol as a diuretic align with previous literature. However, patients with methamphetamine lack the increased UO as a cause for their increased fluid requirements.
Negative pressure wound therapy (NPWT) dressings are beneficial tools for promoting granulation tissue and wound healing. An NPWT dressing with instillation and dwell time (NPWTi-d) is becoming more ...frequently used to provide daily, effective wound cleansing between surgical debridement procedures. Either saline or other wound solutions, such has hypochlorous acid wound solution, can be instilled in small volume aliquots to irrigate the wound periodically.
This case series describes the effective use of NPWTi-d in conjunction with hypochlorous acid (HOCl) solution in 10 patients with necrotizing soft tissue infections (NSTIs).
The hospital registry of patients between July 2018 and June 2020 was queried to identify patients older than were 18 years or older, whose wounds were managed intermittently with NPWTi-d using HOCl wound solution, regardless of wound etiology. Wound and patient demographics were reported.
A total of 10 cases in which NPWTi-d was utilized in conjunction with HOCl were identified. Of the 10 patients, 6 were admitted for NSTIs, 2 were admitted for sacral decubitus ulcers, and 2 were admitted for burn injuries. The patients' wounds ranged from 30 cm2 to 1000 cm2, and 80% of patients ultimately underwent skin grafting for wound closure.
This case series highlights the spectrum of wounds that can be managed with NPWTi-d dressings to yield a clean wound environment to promote healing and preparation for wound closure.
