Epidemiology and risk prediction of patients with severe burns admitted to a burn intensive care unit in a burn center in beijing: A 5-year retrospective study

Esketamine use for primary intelligent analgesia in adults with severe burns: A double-blind randomized trial with effects on analgesic efficacy, gastrointestinal function and mental state

BACKGROUND

Opioid consumption for analgesia in burn patients is enormous. Non-opioid analgesics for burn pain management may result in opioid sparing, reducing opioid-related adverse reactions and drug tolerance or addiction.

METHODS

A dual-center, randomized controlled trial assessed Esketamine for the perioperative period in patients with severe [20-50 % total body surface area (TBSA)] and extensive (≥ 50 % TBSA) burns, comparing analgesia with standard anesthesia. Sixty patients were randomly allocated (1:1 ratio) to two arms. In the Treatment Arm, patients received intra-operative Esketamine and postoperative intravenous primary intelligent analgesia pump with Esketamine. Patients in the Control Arm received the same intervention as Treatment Arm without Esketamine. The primary endpoint was subjective analgesic efficacy (SAE) evaluated on Day 28 or the day before hospital discharge. Secondary outcomes included the postoperative Numeric Pain Rating (NPR) Scale at rest (NPRr) and during movement (NPRm) and opioid consumption. Gastrointestinal dysfunction Scores (GIDS) and serum markers of intestinal injury [intestinal fatty acid-binding protein 2 (iFabp2) and apolipoproteinA2 (ApoA2)] were measured in the 1st and 4th post-injury weeks. Depression and sleep quality were assessed by relevant questionnaires.

RESULTS

Fifty-five patients were included in the analysis. Esketamine-treated Arm recorded a better analgesic efficacy than the Control Arm (proportion of patients with Grade 1 or 2 SAE scores, 67.9 % vs. 40.7 %, p = 0.022). Esketamine-treated patients had lower NPRm values (p = 0.033) and lower daily opioid consumption (p = 0.033) when compared with Controls. Esketamine-treated patients showed comparable gastrointestinal recovery to those in the Control Arm. The overall sleep quality might be improved in the Treatment Arm.

CONCLUSIONS

Esketamine use is safe for perioperative primary intelligent analgesia of severe burns, resulting in improved resting pain control and lower opioid requirements.

TRIAL REGISTRATION

The trial was registered at the Chinese Clinical Trial Registry (www.chictr.org.cn/) (ChiCTR2000034069).

Epidemiological and clinical characteristics of severe burns in adults: A retrospective study at a burn centre in Suzhou, China

Severe burns lead to malformations and higher mortality and have long-term social consequences. We aimed to analyse the epidemiologic characteristics and clinical outcomes of severe burn patients hospitalized in a major burn centre in Eastern China. This study included severe burns patients hospitalized in our hospital from 2017 to 2022. We extracted all data from electronic medical records for retrospective analysis. Burn scoring systems were calculated for all patients. The median age of the patients was 49.00 years, with 62.13% of them aged between 30 and 59 years. Of the 375 adult patients, 256 were male and 119 were female. The major cause of burns was flame (46.1%), followed by explosion (35.2%). The median total body surface area was 40%. Sixty-three percent of patients suffered an inhalation injury and 125 patients (33.3%) developed complications during hospitalization. The average mortality was 5.3%. Higher mortality rates are associated with advanced age, flame burns, larger full-thickness burns area and total body surface area, inhalation injuries and combined burn complications. Severe burns often occur in middle-aged men. Governments and companies need to improve the safety of living and working environments. It is essential to develop treatment strategies based on risk factors for burn deaths and improve the quality of medical care.

Epidemiological and clinical characteristics of burns in adults: a 6-year retrospective study in a major burn center in Suzhou, China

Background

Burns are a prevalent form of unintentional injury and a significant public health concern in developing countries. We aimed to investigate the epidemiological and clinical characteristics of adult burn patients at a major center in Eastern China.

Methods

This 6-year retrospective study analyzed patients with varying degrees of burns between January 2017 and December 2022 at the Suzhou Burns and Trauma Center. The study extracted demographic, clinical, and epidemiological data from electronic medical records for analysis.

Results

The study included 3,258 adult patients, of which 64.3% were male. The largest age group affected 30-59-year-old adults (63.04%). Scalds were the leading cause of burns (1,346, 41.31%), followed by flames (1,271, 39.01%). The majority of burn hospitalizations were those with moderate burns (1791, 54.97%). The morbidity rate was low at 0.68%, while mortality was strongly associated with age, etiology, and total body surface area. Patients with certain types of burns, such as explosions, hot crush injuries, and electric burns had more operations, longer lengths of hospital stay, and higher costs compared to those with scalds and flame injuries.

Conclusion

Different prevention strategies should be formulated according to different etiologies, ages, and genders.

Why do people get burned? Qualitative analysis of the causes of burns in a large survey of burn survivors

BACKGROUND

Understanding the national epidemiology of burns is necessary for effective planning of prevention and treatment services. However, epidemiological studies of burns have often focused on short-term and retrospective investigations of a specific group of burned patients in Iran. Therefore, we conduct a comprehensive study from August 2016 to October 2017, in the Burn Research Center of Iran University of Medical Sciences on approximately 1700 hospitalized burn patients at Motahari Hospital to identify the underlying causes of burns. In this study, an open-ended question was asked about how the burn occurred in the patients. The current study was designed and conducted for the qualitatively analyzing of the responses to this question, using the content analysis method, in order to maximize its use in policymaking and prevention.

METHODS

Content analysis of written responses to open-ended questions was done as a part of a large questionnaire survey. This survey was conducted by face-to-face interview at a national referral center for burn injuries.

RESULTS

Answers from 1595 patients were coded and the underlying causes of injury were categorized into three themes and 43 subthemes. These underlying causes were lack of knowledge and awareness, inappropriate equipment, and inevitable accidents. The underlying cause of lack of knowledge and awareness had the highest proportion in causing burns in both men and women. The most common subthemes in descending order included lack of skills, dangerous actions, improper location of hot liquids, individual mistakes, and improper use of flammable materials. The top five subthemes with the highest average percentage of burn in patients in descending order were deficiency of residential equipment, self-immolation, accidents, inappropriate location of flammable materials, and unsafe kitchen appliances.

CONCLUSION

The focus of prevention programs on educating and increasing awareness of individuals, preferably women, is suggested. Educational programs, tailored to occupational standards and workplace and household equipment, are recommended for men in work environments.

A comparative study of the predictive value of four models for death in patients with severe burns

OBJECTIVE

To assess the prognostic value of the Ryan score, Belgian Outcome of Burn Injury (BOBI) score,revised Baux (rBaux) score, and a new model (a Logit(P)-based scoring method created in 2020) for predicting mortality risk in patients with extremely severe burns and to conduct a comparative analysis.

METHODS

A retrospective analysis was conducted on 599 burn patients who met the inclusion criteria and were admitted to the burn unit of the First Affiliated Hospital of Nanchang University from 2017 to 2022. Relevant information was collected, and receiver operating characteristic (ROC) curves, calibration curves, and decision curve analysis (DCA) were plotted for each of the four models in assessing mortality in these burn patients using both age-stratified and unstratified forms. The ROC curve section was further compared with the area under the curve (AUC), optimal cutoff value, as well as its sensitivity and specificity. Additionally, the quality of the AUC was assessed using the Delong test.

RESULT

Among the patients who met the inclusion criteria, 532 were in the survival group and 67 in the death group. Irrespective of age stratification, the novel model exhibited superior performance with an AUC of 0.868 (95% CI: 0.838-0.894) among all four models predicting mortality risk in included patients, and also demonstrated better AUC quality than other models; the calibration curves showed that the accuracy of all four models was good; the DCA curves showed that the clinical utility of the novel model and rBuax score were better. In the comparison of four scoring models across different age groups, the new model demonstrated the largest AUC in both 0-19 years (0.954, 95% CI 0.914-0.979) and 20-59 years groups (0.838, 95% CI 0.793-0.877), while rBuax score exhibited the highest AUC in ≥ 60 years group (0.708, 95% CI of 0.602-0.800). The calibration curves showed that the four models exhibited greater accuracy within the age range of 20-59 years, while the DCA curves indicated that both the novel model and rBuax score scale displayed better prediction in both the 20-59 and ≥ 60 years groups.

CONCLUSIONS

All four models demonstrate accurate and effective prognostication for patients with severe burns. Both the novel model and rBaux score exhibit enhanced prediction utility. In terms of the model itself alone, the new model is not simpler than, for example, the rBaux score, and whether it can be applied clinicallyinvolves further study.

The gut microbiota regulates the depressive-type behaviors and inflammatory processes after severe burn injuries in mice

An emerging number of studies have recently revealed the correlation between burn injuries and psychological disorders. Gut microbiota and inflammatory factors may play a vital role in this process. Nevertheless, there are few studies conducted to disclose the potential mechanism of the gut microbiota between depression and burn injuries. In this study, we constructed a burn model of C57BL/6 mice, which showed that the symptom of depression became more and more severe with the burn of mice lasted longer. Meanwhile, there are significant differences of composition of gut microbiota among mice before and after burn. Then, we tested the inflammatory factors in the brain and peripheral blood, which showed an increased expression of Iba1, VWF, TNF-α and IL-6, and a decreased expression of IL-10 in burn mice. In addition, the expression of zonula occludens-1 (ZO-1) in cecum showed a down-regulation in burn mice, which indicated impaired intestinal barrier function. Lastly, the crossing fecal microbiota transplantation (FMT) and cohousing experiment were conducted to determine the functions of cross-transplantation of fecal microbiota on the depressive-type behaviours in burned mice. According to the score of Tail suspension test (TST), the burn mice were divided into two groups: Resilient mice (no-depressed mice) and Abnormal mice (depressed mice). After abnormal mice were transplanted with fecal microbiota of resilient mice, the symptom of depression was improved, and the expression of TNF-α, IL-6 and IL-10 return to normal levels (P < 0.05). On the contrary, after resilient mice were transplanted with fecal microbiota of abnormal mice both the TST scores and inflammatory factor developed depressive-type changes. In conclusion, our study demonstrated the changes of gut microbiota and inflammatory factors in depressed burn mice and non-depressed burn mice. The gut microbiota dysbiosis could impaired intestinal barrier function and lead to neuroinflammation, and this phenomenon could be significantly mitigated by FMT.

Blood Stream Infections in Burns: A 14-Year Cohort Analysis

BACKGROUND

Blood stream infections are a significant cause of morbidity and mortality in burns, and pathogen identification is important for treatment. This study aims to characterize the microbiology of these infections and the association between the infecting pathogen and the hospitalization course.

METHODS

We conducted a cohort study that included records of burn patients treated at the Soroka University Medical Center between 2007-2020. Statistical analysis of demographic and clinical data was performed to explore relationships between burn characteristics and outcomes. Patients with positive blood cultures were divided into four groups: Gram-positive, Gram-negative, mixed-bacterial, and fungal.

RESULTS

Of the 2029 burn patients hospitalized, 11.7% had positive blood cultures. The most common pathogens were Candida and Pseudomonas. We found significant differences in ICU admission, need for surgery, and mortality between the infected and non-infected groups (p < 0.001). Pathogen groups differed significantly mean TBSA, ICU admission, need for surgery, and mortality (p < 0.001). Multivariate analysis showed flame (OR 2.84) and electric burns (OR 4.58) were independent risk factors for ICU admission and surgical intervention (p < 0.001). Gram-negative bacterial infection was found to be an independent predictor of mortality (OR = 9.29, p < 0.001).

CONCLUSIONS

Anticipating specific pathogens which are associated with certain burn characteristics may help guide future therapy.
