Renal outcomes of intensive care burn patients in an Asian tertiary centre

IntroductionAcute kidney injury (AKI) is a frequent complication of severe burn injury and is associated with a high mortality rate of up to 80%. We aimed to establish the incidence, mortality rate, and factors related to mortality in adult patients with severe burn injury and AKI with renal replacement therapy (RRT) in Singapore.MethodsWe performed a retrospective cohort study of severely burned patients who were admitted to the Burns Intensive Care Unit (BICU) at the Singapore General Hospital (SGH) from January 2008 to December 2016. We compared patients with AKI with RRT who survived with those who did not survive. As there were changes in the protocol for burns management after 2013, we also compared patients with AKI with RRT who survived with non-survivors in each of the 2008–2012 and 2013–2016 cohorts.ResultsData of 201 patients were studied. The incidence of AKI with RRT use in severe burn injury was 21.9% and their mortality rate was 50.0%. The non-survivors had significantly higher median burned total body surface area (p = 0.043), earlier AKI (p = 0.046), earlier use of RRT (p = 0.035), lower rate of renal recovery (p = <0.0001), higher rates of adult respiratory distress syndrome (ARDS) (p = 0.005) and shock with vasopressors (p = 0.009) compared to the survivors. The survival rate was 36.8% in the 2008–2012 cohort, but improved to 60.0% in the 2013–2016 cohort. In the 2008–2012 cohort, the non-survivors developed AKI earlier (day 0 admission vs. day 3 admission, p = 0.039), and were initiated on RRT at lower serum creatinine level (173.5 μmol/L vs. 254.0 μmol/L, p = 0.042), when compared to the survivors in this same cohort. On the other hand, there were no significant differences in the renal status and fluid balance parameters between the non-survivors and survivors in the 2013–2016 cohort.ConclusionsThe incidence of AKI with RRT in the Singapore study cohort was high, but their mortality rate was relatively lower compared to other study cohorts. Severity of AKI and use of RRT were associated with poor prognosis. Large scale study is required to further study the risk factors for mortality in this group of patients and establish cause-and-effect relationship.     

Epidemiology of hospitalized burn patients in a tertiary care hospital in South India

Background

The epidemiological pattern of burns varies widely in different parts of the world. To suggest effective preventive measures, an insight into the pattern of injury is desirable. However, data on burn victims and outcome is limited from this part of the world.

Methods

This study was conducted in the Department of Surgery, from April 2006 to April 2007. All consecutive patients with major burns admitted for in-hospital treatment during the study period were included in the study. The data collected included age, gender, cause and mode of burns, presence or absence of inhalational injury, facial burns, time delay from burn injury to admission in the hospital, burns depth, total body surface area distribution of burns, associated injuries and co-morbid illness, microbiological profile and outcome. Inhalational injury was assessed by clinical examination as bronchoscopy was not available.

Results

A total of 222 consecutive patients admitted for in-hospital treatment of burn injury were included in the study. 177 patients were adults and 45 were <13 years of age. The female:male ratio was 1.7:1. In adults, 52.5% of burns were due to non-intentional injury and 43.9% were due to self-immolation. In patients <13 years of age, 95.6% of cases were due to non-intentional injury. The mean TBSA was 48.75% and 30.18% of patients had predominantly deep burns. The overall mortality was 60.8%. The predominant organisms colonizing the burn wound were Pseudomonas aeruginosa (81.1%) followed by Acinetobacter species and MRSA. Multivariate logistic regression analysis of factors predicting survival in patients with burn injury showed that TBSA > 30%, age > 20 years, female gender and presence of facial injury were statistically significant as predictors of risk of death.

Conclusions

In patients with burns, total body surface area involvement more than 30%, age more than 20 years, female gender and presence of facial injury are statistically significant, as predictors of poor outcome and risk of death. The strongest association was seen with facial injury, which increased the risk of death by fourfold.     

Yeast from burn patients at a major burn centre of China

Aim

This study presents fungi and their characteristics identified from burn patients at a major Chinese burn centre.

Methods

All burns patients admitted to our Burn Research Institute from 2003 to 2006 inclusive were included in this study. Once fungal infection was suspected clinically, samples including wound tissue, blood, urine, stool and sputum were harvested for the culture of yeast. The sensitivities of the identified yeast were determined and the positive samples and cases were analysed.

Results

Out of a total of 3909 cases, 467 patients were clinically suspected of fungal infection, of which 1970 samples were taken for yeast culture. A total of 38 samples and 36 patients tested positive. The three most positive samples were urine, blood and catheter. Candida tropicalis was identified as the most common yeast type (42.1%), followed by Candida albicans (31.6%), Candida famata (T. Famata) (10.5%) and Candida glabrata (T. Glabrata) (7.9%). Except for C. galbrata, most of the yeast strains found in the study were sensitive to the routine antimycotic agents. There were eight deaths in the 36 positive patients. As much as 83.3% of the positive cases suffered burns of more than 50% total body surface area (TBSA) and half of the positive cases were greater than 80% TBSA. A total of 78.95% of the positive samples were taken from patients after 2 weeks post-burn injury.

Conclusion

A profile of the fungi isolated from burn patients in a major Chinese burn centre is presented.     

Laparoscopic restorative proctocolectomy: a 10‐year experience of an evolving technique

Aim Restorative proctocolectomy is the definitive procedure for ulcerative colitis. The potential benefits of a minimal invasive approach make it appropriate to consider this approach provided that there are no adverse effects. The aim of the present study was to report our experience of laparoscopic assisted and ‘total’ laparoscopic restorative proctocolectomy (LRPC) and to highlight the difficulties encountered and the functional results obtained. Method Electronic data were prospectively collected from all patients who underwent laparoscopic restorative proctocolectomy (LRPC) from October 1999 to April 2010. Results Seventy‐two (40 male) patients [median body mass index 24 (19–48) kg/m²] underwent LRPC over 10 years. Three had cancer. Forty‐two had undergone a previous colectomy (laparoscopic in 38). There were 40 W‐ and 32 J‐pouch reconstructions; seven were single‐port procedures. The median operation time was 210 (75–330) min. There were five (7%) conversions, one of which resulted in immediate pouch failure. The median time to full diet was 36 (4–168) h, with a median hospital stay of 7 (2–64) days. There were seven (10%) readmissions. Complications were immediate (3%), early (22%) and long term (11%). The incidence of failure (excision or indefinite diversion) was 2.7%. The stoma has been closed in 67 patients. Median frequency of defaecation was 4/24 h, with normal continence in 90% and the ability to defer during the day in 98%. There was no new case of impotence or dyspareunia. Conclusion Laparoscopic restorative proctocolectomy is safe and gives good results when performed by an experienced laparoscopic surgeon.     

Vacuum‐assisted closure therapy for vascular graft infection (Szilagyi grade III) in the groin—a 10‐year multi‐center experience

The aim of the study was to evaluate the benefit of vacuum‐assisted closure (VAC) therapy in the management of deep, alloplastic graft infections (Szilagyi grade III) in the groin. From 2000 to 2009, we identified and included in our study 72 deep inguinal infections in 68 patients, involving native as well as synthetic graft or patch material. There were 29 early graft infections (<30 days after implantation) and 43 late infections (≥30 days after implantation). Among these, 17 cases involved native grafts/patches (12 grafts and 5 patches), while 55 cases involved non‐native grafts/patches [26 polytetrafluorethylene (PTFE) grafts and 24 Dacron grafts (Haemashield, Meadox Medical, Boston Scientific Corporation, Natick, NY; Gelsoft graft, Vascutek, Inchinnan, Renfrewshire, Scotland, UK; Intervascular, Mahwah, NJ); INVISTA, and 5 Vascu‐Guard^? bovine pericardial patches; Synovis Surgical Innovation]. All patients were treated with multiple wound debridements, graft salvage, sartorius myoplasty, intravenous antibiotics and VAC therapy until thorough surface healing was achieved. Exclusion criteria were an alloplastic graft infection with proximal expansion above the inguinal ligament, blood culture positive for septicaemia or septic anastomotic herald or overt bleeding. Nine months after initiation of therapy, overall, graft/patch salvage was achieved in 61 of 72 (84·7%) cases. Of the native graft/patch group, infected graft material was replaced with an autogenous great saphenous vein graft or patch in four patients (23·5%). In the non‐native group, vein or synthetic graft preservation without revision was achieved in 48 of 55 (87·3%) patients. The mean duration of VAC therapy was 16 ± 7·7 days, and postoperative mean hospital stay was 25·3 ± 8·5 days. In 23 of 72 (31·9%) cases, a secondary closure of the wound was achieved; in the other 49 cases, wound healing was achieved by meshed split‐thickness skin grafting. Mean wound healing time for all wounds was 24·3 ± 12·5 days. Specific complications during VAC therapy were wound fluid retention in 2 cases and an increased need for analgesics in 12 cases (16·66%). Negative pressure wound therapy (NPWT) has been reported to be useful in the treatment of severe wound infections. Even in the presence of synthetic vascular graft material, NPWT can greatly simplify challenging wound‐healing problems leading to wound dehiscence and its sequelae. Our long‐term experience demonstrates the safety and effectiveness of VAC therapy in the management of deep graft infections.     

The increasing trend in alcohol-related burns: It's impact on a tertiary burn centre

Introduction

The incidence of alcohol-related hospital admissions is a worldwide problem and currently costs the UK National Health Service approximately 4% of its annual budget. 40% of men and 22% of women drink over the recommended UK weekly allowance. The purpose of our study was to examine the trend in alcohol-related admissions to a tertiary burns unit over a 5-year period.

Methodology

All patients admitted were documented for alcohol-related burn, and history of alcohol dependence.

Results

1293 patients admitted between 2003 and 2008 were included in the study. The number of alcohol-related burns were as follows: 2003: 6%; 2004: 10%; 2005: 16%; 2006: 9%; 2007: 19%; 2008: 19%. This increasing trend was highly significant (p < 0.0001). Alcohol-related burns had a higher incidence of flame injury (60%) and a subsequent longer length of stay (12.5 vs. 7.9, p = 0.04). Alcohol dependence was noted in 54% of all alcohol-related burns and in 5% of the non-alcohol-related burns.

Discussion

The number of alcohol-related burns admitted to a tertiary burn unit is increasing and now comprises of nearly 20% of all admissions. This highlights the growing burden of alcohol on health and the need to address it at both a national and regional level.     

Perineal burn contractures: An experience in tertiary hospital of a Himalayan State

Perineal burn contracture is a rare burn sequel. We conducted a retrospective analysis of cases with perineal burn contractures managed in a tertiary care centre of a Himalayan state. We found that all cases sustained burn injury from burning firewood and the time of presentation was two to six years after the burn injury. We analyzed our treatment method and have classified these contractures into two types.     

‘HYPAFIX’: NEW TECHNIQUE OF SKIN GRAFT FIXATION

A new technique for split skin graft fixation using ‘hypafixy’ adhesive dressing is described. Ninety-three patients with bums involving < 20% body surface area grafted at the adelaide children's hospital during february 1985-may 1987 were reviewed. Comparisons were made between the results of standard fixation and hypafix methods. The hypafix technique showed itself to be simple and reliable, affording considerable versatility and allowing early mobilisation without splintage or sedation. The adhesive is readily loosened with ungvita ointment allowing the dressing to be removed painlessly. In this study its use has shortened both the length of inpalient stay and outpatient follow-up in the scar management programme.     

Characteristics of paediatric burns seen at a tertiary centre in a low income country: a five year (2004-2008) study

Background

Children are the most risk prone in cases of burns. The previous epidemiologic study of paediatric burns in Lagos-Nigeria was carried four decades ago. A new study becomes necessary in view of the increasing incidences of petroleum related fire disasters in Nigeria.

Patients and methods

: Children up to the age of 14 years admitted for major burns at the Lagos State University Teaching Hospital (LASUTH), Ikeja-Lagos, Nigeria between January 1, 2004 and December 31, 2008 were studied. Information about the demographics, mechanism/circumstances of burns, associated injuries, surface extent (TBSA) and depth, modes of management and outcome, length of admission, and post mortem findings in cases of death were collected.

Results

: A total of 298 children with major burns were seen; 198 were males and 100 females. The ages ranged from 1 day to 14 years with mean of 4.56 ± 3.95 years. Forty percent of the cases occurred among the toddlers and 25.5% in the 2-5 years age group. Fire was the leading cause of burns, occurring in 198 (66.4%) cases. The TBSA ranged from 1% to 100% with mean of 29.67 ± 21.98. The mortality rate was 29.9%. Autopsy showed asphyxia as the primary cause of death in 14 (48.27%) cases, multiple organ dysfunctions in 27.59% and septicaemia in 13.79%.

Conclusion

This study identifies the main causes of paediatric burns and the major factors responsible for morbidity and mortality at the present time in a low income country. The level of awareness about burns prevention among the populace and health care facilities should be improved.     

Total full-thickness skin grafting for treating patients with extensive facial burn injury: A 10-year experience

IntroductionFacial burns are not only a severe burn injury, but result in psychological disturbance. The improvement of the methods of treating facial burns remains topical. The aim of the study was to evaluate the effectiveness of approach based on full-thickness skin autografting for facial burn injuries.MethodsDuring 2000–2019, ninety seven patients with the facial burn were treated in Burn Center. All patient were divided into two groups. The comparative analysis between groups was done.ResultsGroup A was treated with full-thickness skin grafts (42 patients – 43.3%). Since 2010, total full-thickness skin graft was used in 11 patients from Group A. In group B, 55 patients (56.7%) were treated with split-thickness skin grafts, including 9 patients (16.4%) with total split-thickness skin graft transplantation. Total full-thickness skin graft was performed in case of a deep and extensive facial burn and cicatricial deformities. During the long-term period, a positive cosmetic result and the absence of indications for reconstructive operations were noted.ConclusionThe approach of facial burn treatment based on total full-thickness skin graft allows conditions for engraftment and adaptation of autograft, reduces the risk of scar developing and achieves maximum cosmetic results of treatment.
