Burn management in sub-Saharan Africa: Opportunities for implementation of dedicated training and development of specialty centers

Background

In low- and middle-income countries burn injuries remain responsible for a large burden of death and disability. Given an annual worldwide incidence of almost 11 million new individuals affected per year, major burn injuries have a higher annual incidence than HIV and tuberculosis combined.

Methods

A survey instrument was adapted for use as an international assessment tool and then used to measure the availability of personnel, materials, equipment, medicines, and facility resources in nine Rwandan hospitals, including three referral centers.

Results

Forty-four percent of surveyed hospitals had a dedicated acute-care burn ward, while two-thirds had intensive care options. Relevant wound-care supplies were widely available, but gaps in the availability of critical pieces of equipment such as monitors, ventilators, infusion pumps, electrocautery, and dermatomes were discovered in many of the surveyed institutions, including referral hospitals. Early excision and grafting were not performed in any of the hospitals and there were no physicians with specialty training in burn care.

Conclusions

Whereas all surveyed hospitals were theoretically equipped to handle the initial resuscitation of burn patients, none of the hospitals were capable of delivering comprehensive care due to gaps in equipment, personnel, protocols, and training. Accordingly, steps to improve capacity to care for those with thermal injury should include training of physicians specialized in critical care and trauma surgery, as well as plastic and reconstructive surgery. Consideration should be given to creation of national referral centers specializing in burn care.     

Antibiotic resistance and OXA-type carbapenemases-encoding genes in airborne Acinetobacter baumannii isolated from burn wards

The study was conducted to investigate drug resistance, OXA-type carbapenemases-encoding genes and genetic diversity in airborne Acinetobacter baumannii (A. baumannii) in burn wards. Airborne A. baumannii were collected in burn wards and their corridors using Andersen 6-stage air sampler from January to June 2011. The isolates susceptibility to 13 commonly used antibiotics was examined according to the CLSI guidelines; OXA-type carbapenemases-encoding genes and molecular diversity of isolates were analyzed, respectively. A total of 16 non-repetitive A. baumannii were isolated, with 10 strains having a resistance rate of greater than 50% against the 13 antibiotics. The resistance rate against ceftriaxone, cyclophosvnamide, ciprofloxacin, and imipenem was 93.75% (15/16), but no isolate observed to be resistant to cefoperazone/sulbactam. Resistance gene analyses showed that all 16 isolates carried OXA-51, and 15 isolates carried OXA-23 except No.15; but OXA-24 and OXA-58 resistance genes not detected. The isolates were classified into 13 genotypes (A-M) according to repetitive extragenic palindromic sequence PCR (REP-PCR) results and only six isolates had a homology ≥90%. In conclusion, airborne A. baumannii in the burn wards had multidrug resistance and complex molecular diversity, and OXA-23 and OXA-51 were dominant mechanisms for resisting carbapenems.     

Neutrophil gelatinase associated lipocalin as an indicator of acute kidney injury and inflammation in burned children

Introduction

Neutrophil gelatinase associated lipocalin (NGAL) is a novel predictor of acute kidney injury (AKI), which increases with inflammation. We aimed to assess whether serum NGAL (SNGAL) and urine NGAL (UNGAL) can predict AKI in burned children.

Methods

Patients were referred within the 12 h of burn to our center. Serum samples for SNGAL, C-reactive protein (CRP), procalcitonin (PCT) and urine for UNGAL, microalbumine (Umalb), creatinine (Ucr) were obtained at both admission and the 5th day after burn. Blood urea nitrogen (BUN) and serum creatinine (Scr) were examined daily.

Results

Twenty-two subjects were enrolled and six (27.2%) of them developed AKI within the 48 h of injury. Burn size and abbreviated burn severity index (ABSI) were significantly increased in patients with AKI. CRP, PCT, SNGAL and UNGAL levels at admission and day 5 were significantly higher in patients with AKI than in those without AKI and controls. Scr was not significant between AKI and non-AKI groups at hospital days 1 and 5. A SNGAL level of 315 ng/ml and a UNGAL level of 100 ng/ml were determined as predictive cut-off values of AKI at admission (sensitivity and specificity: 71.4%, 83.3% and 93.3%, 93.7%, respectively). SNGAL and UNGAL were positively correlated with CRP, PCT, ABSI and Umalb/Ucr.

Conclusion

SNGAL and UNGAL are good early predictors of AKI in children with severe burn. NGAL might reflect the severity of burn insult and also could be used as an indicator of inflammation in burn children.     

Influencing factors of the quality of life in Chinese burn patients: Investigation with adapted Chinese version of the BSHS-B

Objective

The study aims to evaluate the quality of life (QOL) in burn patients in China and find out principal influencing factors, so as to provide evidence for interventions.

Methods

A total of 271 burn patients in three major burn units in China were asked to fill in the adapted Chinese version (ACV) of the Burn Specific Health Scale-Brief (ACV BSHS-B) in order to seek out the principal influencing factors in combination with a self-designed demographic and disease condition questionnaire. Multivariable linear regression was used to analyse the principal influencing factors.

Results

The findings showed that there were seven principal influencing factors for the overall ACV BSHS-B score. They were: percent total body surface area (TBSA) burned (with the standardised regression coefficient being −0.594), burn area of lower limber (0.241), itch level (−0.227), pain level (−0.220), gender (0.217), mechanical ventilation (0.216) and hand deformity (−0.141).

Conclusion

QOL decreased in burn patients to different degrees depending on the intensity of burns. With a better understanding of influencing factors of burn patients’ QOL, the medical and nursing staff can take specific countermeasures to help patients gain a higher QOL.     

Spread of extended-spectrum β-lactamase genes of bla OXA-10, bla PER-1 and bla CTX-M in Pseudomonas aeruginosa strains isolated from burn patients

BackgroundPseudomonas aeruginosa is resistant to many antibiotics due to production of different classes of extended spectrum β-lactamases (ESBLs). Prevalence of ESBLs among P. aeruginosa has been increased in recent years, demonstrate a serious health problem especially in burn units worldwide.ObjectivePresent study was designed to determine the ESBL producing strains and identify the genes encoding three different ESBLs of bla PER-1, bla OXA-10 and bla CTX-M genes in P. aeruginosa isolates from burn patients.MethodsIn total 185 clinical isolates of P. aeruginosa were collected from infectious wounds of hospitalized burn patients. Antimicrobial susceptibility testing and phenotypic detection of ESBL were performed by disk diffusion method and Double disk Synergy Test (DDST). Polymerase Chain Reaction (PCR) was done for detection of bla OXA-10, bla PER-1 and bla CTX-M ESBL encoding genes.ResultsIn total, 176 (95.13%) isolates were multidrug resistant. The DDST demonstrated 96 (51.9%) isolates as putative ESBL producers with 100% or highly resistance to ofloxacin, cephalexin, aztreonam (97.57%) and ceftriaxone (91.6%). By PCR amplification, bla PER-1, bla OXA-10 and bla CTX-M genes were detected in 52 (54.16%), 66 (68.75%) and 1 (1.04%) isolates of ESBL producers respectively. Forty-three isolates (44.79%) were simultaneously positive for both bla OXA-10 and bla PER-1 related genes.ConclusionThe rate of ESBL producing P. aeruginosa was notable in present study. Since there are only limited effective antibiotics against the bacterium, therefore all isolates must be investigated by antimicrobial susceptibility testing, which limits resistance development in burn units and helps the management of treatment strategy.     

Treatment of sandal burns of the feet in children in a moist environment

Burns to children's feet are often due to scalds, from hot tap water, as an infant's skin is thinner and hence more susceptible to a full-thickness injury.     

A novel rapid and selective enzymatic debridement agent for burn wound management: A multi-center RCT

Objectives

Excisional debridement followed by autografting is the standard of care (SOC) for deep burns, but is associated with serious potential complications. Conservative, non-surgical and current enzymatic debridement methods are inefficiently slow. We determined whether a non-surgical option of rapid enzymatic debridement with the debriding enzyme NexoBrid™ (NXB) would reduce need for surgery while achieving similar esthetic and functional outcomes as SOC.

Methods

We conducted a multi-center, open-label, randomized, controlled clinical trial including patients aged 4-55 years with deep partial and full thickness burns covering 5-30% of their total body surface area (TBSA). Patients were randomly assigned to burn debridement with NXB (applied for 4 h) or SOC, which included surgical excisional or non-surgical debridement.

Results

NXB significantly reduced the time from injury to complete débridement (2.2 vs. 8.7 days, P < 0.0001), need for surgery (24.5% vs. 70.0%, P < 0.0001), the area of burns excised (13.1% vs. 56.7%, P < 0.0001) and the need for autografting (17.9% vs. 34.1%, P = 0.01). Scar quality and quality of life scores were similar in both study groups as were the rates of adverse events.

Conclusions

Enzymatic débridement with NXB resulted in reduced need for and extent of surgery compared with SOC while achieving comparable long-term results in patients with deep burns.

Development of an inter-professional clinical practice guideline for vocational evaluation following severe burn

Purpose

To develop an inter-professional clinical practice guideline for vocational evaluation following severe burn.

Methods

The Canadian Medical Association's (CMA) handbook on clinical practice guideline and the appraisal of guidelines for research and evaluation (AGREE) were used to develop the guideline. The following steps from the CMA handbook were followed: (1) identifying the guideline's objective and questions; (2) systematic literature review; (3) study selection and quality appraisal and (4) development of clear recommendations by key stakeholders. The international classification of function and disability was used as a guiding theoretical framework.

Results

The guideline includes recommendations within seven domains: (1) establishing evaluation purpose and consent; (2) history taking and information gathering; (3) assessment of functional systems: body systems and structures; (4) assessment of functional systems: activity limitations and participation restrictions; (5) identification of key personal and environmental factors; (6) analysis and synthesis; (7) development of evaluation recommendations.

Conclusions

This guideline insures that vocational evaluators use an evidence-based approach to systematically assess elements within the individual, the work, workplace, personal and environmental facilitators and barriers to work participation. The guideline may be useful to clinicians, healthcare teams, employers and individuals with severe burns. Future steps will include guideline pilot testing and endorsement.
