Application of Multifunctional Intelligent Suspension Treatment Beds in Nursing Care of Patients with Extensive Burns

The nursing care of patients with extensive burns by using multifunctional intelligent suspension treatment beds was studied. 40 patients, including 30 males and 10 females, with extensive burns were nursed using multifunctional intelligent suspension treatment beds. First of all, the patients were given psychological care, which was patiently explained, so that they can overcome their fears and be treated with peace of mind. Second, the room temperature and bed temperature were closely monitored. Finally, special attention was paid to the adjustment of rehydration volume, regular detection of plasma electrolytes, prevention of electrolyte disorder, and dehydration. Besides, disinfection and isolation should be performed when using. The results showed that 4 cases (20%) were positive in group A and 8 cases (40%) were positive in group B on the 10th day after injury X 2 = 4.005 , and the incidence of wound infection in group A was significantly lower than that in group B. The use of suspension beds in patients with extensive burns makes them safe and comfortable, and the whole body wound scabs healed faster, as well as the infection was minimized. A suspended bed is especially suitable for the clinical treatment of patients with extensive burns. The advantages of suspended bed can be fully realized by summarizing clinical experience.

Surviving an Extensive Burn Injury Using Advanced Skin Replacement Technologies

There have been significant improvements in the technology available for treating extensive burns in the past decade. This case presents two unique, skin replacement technologies that were used to treat an 86% surface area flame burn in a pediatric patient. A temporary dermal replacement, known as “Novosorb™ Biodegradable Temporizing Matrix” was first used to stabilize the burn injury and remained in place for approximately three months. Given the large burn size and lack of available donor skin for grafting, a permanent skin replacement product known as “Self-Assembled Skin Substitute (SASS)” was then utilized to cover the burns. SASS is a novel technology that was developed to replace skin as an autologous skin graft and is currently available in Canada through a clinical trial for major burns. Ultimately, the concurrent use of these two technologies allowed for the unprecedented survival of a child following an extensive and life-threatening burn injury.

Adipose tissue versus stem cell-derived small extracellular vesicles to enhance the healing of acute burns

Aim: Proper healing of extensive burns remains a healthcare challenge. In the present study, we proposed a distinct therapeutic application of adipose tissue and small extracellular vesicles isolated from human menstrual blood-derived mesenchymal stem cells (MenSC) small extracellular vesicles (sEVs) to enhance the repair of third-degree burn injury. Materials & methods: Mouse model of third-degree burn was used. Adipose tissue in the form of Nano-fat (NF) and MenSC-sEVs was injected subcutaneously at the site of injuries. Results: NF and sEVs were capable of enhancing wound closure and increasing neoangiogenesis. NF was also effective in accelerating the formation of granulation tissue and boosting the thickness of the new epithelial layer. Conclusion: This study demonstrates the effectiveness of NF and MenSC-sEVs as promising therapeutic approaches to facilitate the repair of skin burns.

Retrospective Evaluation Of The Accuracy Of Five Different Severity Scores To Predict The Mortality In Burns Patients

Background Patients with great clinical impairment, due to extensive burns, need to be admitted to intensive care units, in these treatment sites, indices are used to classify the severity of patients. The aim of the study was to compare the accuracy of the FLAMES score in relation to the Acute Physiologic and Chronic Health Evaluation II (APACHE II), the Simplified Acute Physiologic Score II (SAPS II), the Logistic Organ Dysfunction System (LODS) and the Abbreviated Burn Severity Index (ABSI) applied to the severe burn patient facing mortality in an ICU of a reference center for burns in Brazil. Methods A retrospective study conducted in ICU comparing the accuracy the APACHE II, SAPS II, LODS, ABSI and FLAMES instruments were applied to all the selected medical records. To evaluate the accuracy of the SIs, the Receiver Operating Characteristic curve was calculated and the area under the curve (AUC). Results Among the 574 patients included in the study, male individuals (70.13%), with an average age of 44.01 ± 28.64 prevailed and the majority of the burns were caused by accidents (76.53%). The outcome accounted for 35.29% of deaths. It was observed that the FLAMES and ABSI presented the two largest areas under the ROC curves and the highest sensitivities (96% and 89%, respectively). The APACHE II, SAPS II and LODS presented sensitivities equal to or greater than 80%. Conclusions It has been demonstrated that indices specifically developed for burn patients, specifically the FLAMES and ABSI indices, presented better accuracies and prediction performances.

Combined Complex Skin Repair in Patient With Extensive Burns: A Case Report

Auto-skin grafting is the current treatment of choice for extensive burns. Nevertheless, the lack of donor sites for skin grafting remains one of the greatest limiting factors for the treatment of extensively burned patients. We present the case of a 53-year-old male patient with deep and full thickness burns on 91% of the total body surface area. We used the Meek technique for split-thickness skin graft expansion to treat this patient. In order to obtain sufficient skin for grafting, we repeatedly harvested the same anatomical areas. Acceleration of burn wounds, recipient, and donor site healing was achieved by systemic treatment with recombinant human growth hormone and topical recombinant human epidermal growth factors. This combined, complex treatment modality contributed to the successful skin repair in this patient.

Local microbiological monitoring as a basis for determining etiological significance of conditional pathogens: data from a burn intensive care unit

Objective. To assess the etiology of infections, microbial associations and antimicrobial resistance in a burn intensive care unit. Materials and Methods. A microbiological study of 1322 biological samples from 195 patients with extensive burns included 479 blood samples, 82 respiratory samples, 326 urine samples, and 435 wound samples. Antimicrobial susceptibility testing was performed, and coefficients of constancy and associativity (CA), as well as the Jaccard coefficient were calculated. Results. The etiology of infections was represented by: Pseudomonas aeruginosa – 23%, Acinetobacter baumannii – 19.1%, Enterococcus faecalis – 18.6%, Klebsiella pneumoniae – 8.2%, CoNS (coagulasenegative staphylococci) – 8.2%, Staphylococcus aureus – 7.1%, Candida albicans – 7.1%, Candida non-albicans – 3%, other species were isolated with a frequency of less than 2%. Majority of the above mentioned pathogens showed high associativity: non-fermenting rods (NFR), S. aureus, Enterobacterales, E. faecalis, Candida non-albicans formed associations in 60.0%, 88.8%, 83.0%, 83.3% and 65% of cases, respectively. The prevalence of methicillin-resistant strains of S. aureus and CoNS was 71% and 81%, respectively. CoNS showed higher resistance to fluoroquinolones and gentamicin compare to S. aureus: 42% vs 23%, 46% vs 29%, respectively (χ2 = 6.91; p = 0.086; χ2 = 6.58; p = 0.013). E. faecalis showed high resistance rates to aminoglycosides and fluoroquinolones (> 60%). All Gram-positive isolates were completely susceptible to vancomycin, linezolid, tigecycline, and teicoplanin. Resistance rates of Gram-negative bacteria (NFR, K. pneumoniae) to penicillins, cephalosporins, carbapenems (for NFR), and aminoglycosides were high (from 60% to 100%). The most active antimicrobial against NFR was colistin. Resistance of K. pneumoniae isolates to carbapenems was 23%, while other enterobacteria were highly susceptible to carbapenems. Conclusions. The implementation of the local microbiological monitoring made it possible to characterize the qualitative pathogen structure and antimicrobial resistance in our burns intensive care unit. This data will serve as the basis for improving of the infection control and antimicrobial stewardship.
