Airway obstruction is fatal but common among burn patients in the early period after inhalation injury, during which most tracheotomies are performed within 48 h post-injury. Inflammation is common in laryngoscopy; however, the related gene expression has rarely been studied. In this study, we obtained the data of healthy control and patient samples collected within 8-48 hours post-injury from the Gene Expression Omnibus database and classified them into 10 inhalation-injury patients, 6 burn-only, and 10 healthy controls. Differential gene expression was identified between the patient groups; however, principal component analysis and cluster analysis indicated a similarity between groups. Furthermore, enrichment analysis, Kyoto Encyclopedia of Genes and Genomes, and gene set enrichment analyses showed no significant differences in immune regulation and cell adjustment between the patient groups; but differences were shown when comparing either patient group to the healthy control group, including prominent regulation in inflammatory cells, infection, and cell adjustment. Thus, the gene expression in inhalation injury and burn-only patients does not significantly differ in the early period after injury, especially in inflammation, indicating the absence of specific diagnostic markers or anti-inflammatory treatment in inhalation injury patients, with the potential to identify more subtle differences. Further research is warranted.

Large-volume fluid resuscitation remains irreplaceable in the early-stage management of severe burns. We aimed to explore the relationship between fluid volume and other indicators. Data of severe burn patients with successful resuscitation in the early stage was collected. Correlation and linear regression analyses were performed. Multiple linear regression models, related goodness-of-fit assessment (adjusted R-square and Akaike Information Criterion), scatter plots, and paired t-test for two models, and a likelihood ratio test were performed. 96 patients were included. The median of total burn area (TBA) was 70%TBSA, with full thickness burn area (FTBA)/TBA of 0.4, a resuscitation volume of 1.93 mL/kg/%TBSA. Among volume-correlated indicators, two linear regression models were established (Model 1: TBA x weight and tracheotomy; and Model 2: FTBA x weight, partial thickness burn area (PTBA) x weight, and tracheotomy). For these models, close values of Akaike Information Criterion, adjusted R-squares, outliers of the prediction range, and the result of paired t-test, all suggest similarity between two models estimations, while the likelihood ratio test for coefficients of FTBA x weight and PTBA x weight showed a statistical difference. Inhalational injury and decompression surgery only correlated with volume, while Tracheotomy, TBA x weight, FTBA x weight, and PTBA x weight correlated with and were accepted in linear models of volume. Although FTBA and PTBA differed statistically, there may be no need to distinguish them when estimating the resuscitation volume requirements in this patient set. Further study about different depths fluid should be conducted.

The incidence rate of electrical injury has remained stable, while the absolute case number has increased. Amputations, erosions, occlusions, and delayed blood vessel rupture are the common complications. Ectopic implantation salvage has been performed widely in mechanical trauma patients, to preserve viable or possibly viable tissues and organ, without application in the electrical injury patients to the best of our knowledge. Here, we present a case report involving ectopic implantation salvage of the left thumb before contralateral transplantation to the right hand after high-voltage electrical injury. The patient's left thumb remained viable despite necrosis of the left forearm at 3 weeks postinjury. After debridement, we implanted the left thumb to his thigh where it was anastomosed to the lateral circumflex femoral artery's descending branch and great saphenous vein. We replanted the left thumb on the right hand with fixation 6 weeks later. The reassembled right hand remained well-circulated 11 months postreconstruction. We believe this case supports broadening the indication for ectopic implantation salvage surgeries to patients who sustain electrical injuries.
