Evaluating the association between time to skin grafting for truncal burn patients and complications: a comparative cohort study using the National Trauma Data Bank. Int J Surg 2024; 110:4581-4587. [PMID: 39143705 PMCID: PMC11325990 DOI: 10.1097/js9.0000000000001461] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2024] [Accepted: 03/31/2024] [Indexed: 08/16/2024]
Abstract
BACKGROUND The split-thickness skin graft (STSG) procedure is frequently used in the reconstruction of burn-injured patients. This study assessed the impact of graft timing on associated skin complications in patients with torso burns using a comprehensive national database. METHODS Truncal burn (2nd-degree and 3rd-degree burns covering 20-89% TBSA) patients who underwent STSG in the National Trauma Data Bank from 2011 to 2015 were studied. The outcomes examined were graft-related complications (superficial surgical site infections, deep surgical site infections, and graft failure), overall mortality and hospital length of stay (LOS). Patients were compared based on the presence or absence of grafting complications. A linear regression model was used to assess the relationship between hospital LOS and graft timing, considering other variables. RESULTS Among the 853 studied patients, the cohort with graft complications exhibited a significantly prolonged time to STSG (413.0 h compared to 264.6 h, P<0.001) and a higher percentage of patients with pre-existing diabetes (18.5 vs. 8.0%, P=0.008). The multiple logistic regression analysis revealed that both the extended time to STSG (odds=1.001, P=0.003) and pre-existing diabetes (odds=2.790, P=0.010) significantly elevated the likelihood of complications associated with STSG. Notably, this delay did not elevate mortality risks. A positive relationship was found between grafting delay and LOS. CONCLUSION The findings underscore that a prolonged duration to skin grafting contributes to extended hospital stays and increased graft-related complications. However, the role of grafting delay in influencing the mortality of truncal burn patients appeared inconsequential, indicating that mortality may be influenced by various factors.

Abstract
Burns generate every year an important burden of morbidity, being a major global public health problem through prolonged hospitalization, complications, and increased mortality. This study's purpose was to evaluate the serum levels of three adipokines and to establish significant correlations with other circulating molecules and with some clinical parameters. We evaluated 32 children with severe burns (over 25% total burned surface area-TBSA) at 48 h, day 10, and day 21 post burn, and 21 controls. The serum levels of adiponectin, resistin, leptin, tumor necrosis factor-α (TNF-α), plasminogen activator inhibitor-1 (PAI-1), and C-reactive protein (CRP) (among nine other biochemical parameters) were detected by Multiplex technique. Significant statistical differences were obtained for resistin and leptin compared to the control group, in different moments of measurements. Adiponectin serum levels presented statistically significant correlations with hot liquid mechanism of burn, the Revised Baux score, TBSA, resistin, PAI-1, CRP, TNF-α, and triglycerides (TGLs) serum levels. Resistin serum levels presented statistically significant correlations with adiponectin, CRP, PAI-1, leptin, and TNF-α. Additionally, we found statistically significant correlations between leptin serum levels and length of hospitalization, TNF-α, resistin, adiponectin, and PAI-1 serum levels. In severely burned children, adiponectin, resistin, and leptin specifically correlate with clinical parameters and with proteins involved in the systemic inflammatory response and the hypermetabolic response.

Burns 2024:S0305-4179(24)00201-8. [PMID: 39317547 DOI: 10.1016/j.burns.2024.07.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/29/2024] [Revised: 05/20/2024] [Accepted: 07/04/2024] [Indexed: 09/26/2024]
Abstract
BACKGROUND Despite all advances in burn prevention, treatment, acute care, and rehabilitation, burn injuries continue to cause significant mortality and disability in Ethiopia. Thus, this review and meta-analysis aimed to assess the pooled prevalence and the determinants of mortality in Ethiopia. METHODS This systematic review was conducted according to the guidelines of Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). A structured search of databases (Medline/PubMed, Google Scholar, CINAHL, EMBASE, HINARI, and Web of Science) was undertaken. Selection, screening, reviewing, and data extraction were done by independent reviewers using a Microsoft Excel spreadsheet. The quality of the included studies was assessed using the Joanna Briggs Institute (JBI) critical appraisal tool. A random-effects meta-analysis model with a 95 % confidence interval was computed to estimate the pooled effect size (i.e., prevalence and odds ratio). Publication bias was checked using the funnel plot, Egger's, and Begg's tests. The heterogeneity of studies was assessed using I2 statistics. Subgroup analysis based on the region and age group was done. RESULTS This systematic review and meta-analysis included a total of ten studies. The pooled prevalence of mortality among patients with burn injuries in Ethiopia was found to be 6.01 % (95 % CI: 2.75, 9.26). Subgroup analysis based on the region showed that the pooled prevalence of mortality was highest in the Oromia region (12.02 %), followed by the Amhara region (8.5 %). Additionally, subgroup analysis based on patients' ages revealed that the pooled estimates of mortality among all age groups and children were 5.18 % and 7.91 %, respectively. The meta-analysis demonstrated that the extent of burn > 10 % TBSA (OR = 5.04, 95 % CI: 2.72, 9.35), presence of comorbidity (OR = 4.01, 95 % CI: 1.44, 11.18), and presence of a 3rd degree burn (OR = 10.64, 95 % CI: 2.82, 40.16) were significantly associated with mortality among burn patients. CONCLUSION AND RECOMMENDATIONS The national prevalence of mortality among burn patients in Ethiopia was high. The extent of burn, presence of comorbidity, and 3rd degree burns were significant predictors of mortality. We strongly recommend that health care workers give special attention to burn patients with greater extent and depth of burn, and for those who have comorbid diseases.

Abstract
Background: Burns represent a serious health problem, associated with multiple-organ failure, prolonged hospitalization, septic complications, and increased rate of mortality. The main aim of our study was to evaluate the levels of various circulating molecules in children with severe burns (more than 25% TBSA), in three different moments: 48 h, day 10, and day 21 post-burn. Materials and Methods: This study included 32 children with burns produced by flame, hot liquid, and electric arc and 21 controls. Serum plasminogen activator inhibitor-1 (PAI-1), α 1-acid glycoprotein (AGP), C-reactive protein (CRP), and platelet factor 4 (PF4) were detected using the Multiplex technique. Several parameters, such as fibrinogen, leucocyte count, thrombocyte count, triiodothyronine, thyroxine, and thyroid-stimulating hormone were also determined for each patient during hospitalization. Results: Significant statistical differences were obtained for CRP, AGP, and PF4 compared to the control group, in different moments of measurements. Negative correlations between CRP, AGP, and PF4 serum levels and burned body surface, and also the hospitalization period, were observed. Discussions: CRP levels increased in the first 10 days after burn trauma and then decreased after day 21. Serum PAI-1 levels were higher immediately after the burn and started decreasing only after day 10 post-burn. AGP had elevated levels 48 h after the burn, then decreased at 7-10 days afterwards, and once again increased levels after 21 days. PF4 serum levels increased after day 10 since the burning event. Conclusions: Serum CRP, AGP, PAI-1, and PF4 seem to be promising molecules in monitoring patients with a burn within the first 21 days.

Abstract
Pavement burns are more common in locations familiarised with high temperatures and a dry climate zone, but have not previously been reported in temperate climates. We present two cases of patients who suffered pavement burns in the United Kingdom during an unprecedentedly hot day in July 2022. The first case involved a 66-year-old male who suffered partial and full thickness burns requiring excision and skin grafting. The second case involved a 58-year-old female with partial thickness burns also requiring excision and skin grafting. Both patients had pre-existing co-morbidities and their pavement burns were precipitated by heat stroke. Pavement burns represent a mechanism of injury that necessitates increased operative management, length of hospital stay and cost per surface area burned when compared to flame or scald burns (Silver et al., 2015). As a result of global warming, we anticipate extreme heat events, and subsequently pavement burns, to increase in incidence in the United Kingdom. There is opportunity for education of the public and health professionals for prevention.

Abstract
OBJECTIVE Burn bacteremia is related to immune barrier damage, but whether the level of circulating immune cells predicts outcomes in severe burns is still not clear. This study aimed to explore the predictive value of perioperative blood cells of the first surgery after burn for bacteremia and 90-day death. METHODS Data from severe burn patients treated at the First Affiliated Hospital of Sun Yat-sen University from 2011 to 2020 were retrospectively analyzed. Data on monocytes (M), lymphocytes (L), white blood cell-to-platelet ratio (WPR), neutrophil-to-lymphocyte ratio (NLR) in peripheral blood and changes in temperature (T-37) were collected at one day before(X0), the first day after (X1) and the third day after (X3) the primary surgery.Univariate and multivariate logistic regression were used to identify the independent risk factors of bacteremia and death within 90 days, which were used to establish the risk prediction models (xbac and x90d-m) in severely burned patients. Severe burn cases from two other burn centers were selected to verify the prediction models. RESULTS We analyzed 169 severe burn cases in the training dataset, with a 90-day mortality of 21.3% (36/169); 56 (33.1%) patients experienced burn bacteremia. Higher M0, WPR0, NLR0, NLR3, T3-37, ∆M (M0-M3) and lower M3, L3 were associated with higher risk of bacteremia (P < 0.05). Multivariate regression analysis showed that SOFA0, WPR0, M3, and T3-37 were independently associated with bacteremia. The prediction model for bacteremia Xbac = 0.1809 × SOFA0 + 6.532 × WPR0-1.171 × M3 + 0.6987 × T3-37- 2.297. TBSAB, SOFA0, and ∆M (M0-M3) were independently correlated with 90-day mortality. The risk prediction model X90d-m= 0.055 × TBSAB + 0.301 ×SOFA0 + 1.508 × ∆M - 7.196. External validation suggested that the specificity, sensitivity and AUC of the prediction model Xbac was 90.7%, 62.5% and 0.797, respectively; of the prediction model X90d-m was 69.2%, 90.0% and 0.873, respectively. CONCLUSION Peripheral M3, WPR0 and ∆M (M0-M3) during the primary surgery has reasonable predictive ability for bacteremia and 90-day mortality in severe burn patients, which could inform clinical antimicrobial judgment and prognostication.

Abstract
INTRODUCTION Prognostication of burn injury mortality is challenging. Recent mortality prognostication tools have incorporated the percent of full-thickness surface area (FTSA). We hypothesize that the presence of full-thickness burn injury independently increases in-hospital mortality. METHODS We performed a retrospective review of the National Trauma Data Bank (NTDB) from 2007 to 2019 of adults (≥16 years old) with burn injuries. Variables evaluated included basic demographics, presence of inhalation injury, percent TBSA, and percent FTSA burned. The primary outcome was in-hospital mortality. We performed modified Poisson regression modeling adjusting for significant variables to estimate the relative mortality risk. RESULTS 75,816 patients met inclusion criteria. When controlling for TBSA, the presence of a full-thickness burn had a relative risk of in-hospital mortality of 1.42 (95% CI 1.09-1.85, p = 0.008). The predicted probability of mortality was 100% at 50% FTSA. CONCLUSION The presence of full-thickness burns and the proportion of full-thickness burns independently and significantly increased in-hospital mortality. Therefore, clinicians should utilize prognostication models incorporating percent full-thickness burn area to predict mortality more accurately.

Abstract
PURPOSE To investigate the prognostic value of the factors related to the initial surgical management of burn wounds in severely burned patients. METHODS A total of 189 severely burned adult patients who were admitted to our institute between January 2012 and December 2020 and met the inclusion criteria were recruited. Patients were divided into survival and nonsurvival groups. The patient data included sex, age, total burn surface area (TBSA), burn index (BI), inhalation injury, mechanical ventilation, initial surgical management of the burn wound (including post-injury time before surgery, surgical duration, surgical area, intraoperative fluid replenishment, intraoperative blood loss, and intraoperative urine output), and duration in the burn intensive care unit (BICU). Independent samples t tests, Mann-Whitney U tests, and χ 2 tests were performed on these data. those of which with statistically significant differences were subjected to univariate and multivariate Cox regression analyses to identify independent risk factors affecting the prognosis of severely burned patients. Receiver operating characteristic (ROC) curves were plotted, and the area under the curve (AUC), optimal cut-off value were calculated. Patients were divided into two groups, according to the optimal cut-off value of the independent risk factors. The TBSA, surgical area and survival rates of the two groups during hospitalization were analysed. RESULTS The survival group (146 patients) and the nonsurvival group (43 patients) differed significantly in TBSA, burn index, inhalation injury, mechanical ventilation, initial surgical area, intraoperative fluid replenishment, intraoperative blood loss, and duration in the BICU (P<0.05). Univariate Cox regression analysis showed that TBSA, burn index, mechanical ventilation, initial surgical area, intraoperative fluid replenishment, and intraoperative blood loss were risk factors for death in severely burned patients (P<0.05). Multivariate Cox regression analysis showed that the burn index and intraoperative blood loss were independent risk factors for death in severely burned patients (P<0.05). When the intraoperative blood loss during the initial surgical management of burn wounds was used to predict death in 189 severely burned patients, the AUC was 0.637 (95% confidence interval (CI): 0.545-0.730, P=0.006), and the optimal cut-off for intraoperative blood loss was 750 ml. Kaplan-Meier survival analysis showed that the prognosis of the group with intraoperative blood loss ≤750 ml was better than that of the group with intraoperative blood loss >750 ml (P=0.008). Meanwhile, the TBSA and surgical area in the group with intraoperative blood loss ≤750 ml were significantly lower than that of the group with intraoperative blood loss >750 ml (P<0.05). CONCLUSION The burn index and intraoperative blood loss during the initial surgical management of burn wounds are independent risk factors affecting the outcome of severely burned patients with good predictive values. During surgery, haemostatic and anaesthetic strategies should be adopted to reduce bleeding, and the bleeding volume should be controlled within 750 ml to improve the outcome.
