Free Flow-through Anterolateral Thigh Flaps for Wrist High-tension Electrical Burns:A Retrospective Case Series

Objective The objective of this report was to demonstrate the clinical application of free flow-through anterolateral thigh flaps for the treatment of high-tension electrical wrist burns.Methods We collected the data of 8 patients with high-tension electrical wrist burns admitted to Beijing Jishuitan Hospital from January 2014 to December 2018.The clinical and pathological data were extracted from electronic hospital medical records.We obtained follow-up information through clinic visits.Results The injury sites for all 8 patients were the wrists,specifically 5 right and 3 left wrists,all of which were on the flexor side.Five patients had ulnar artery embolism necrosis and patency,with injury to the radial artery.Two patients had ulnar and radial arterial embolization and necrosis.The last patient had ulnar arterial embolization and necrosis with a normal radial artery.After debridement,the wound area ranged from 12 cm×9 cm to 25 cm×16 cm.The diagnoses for the eight patients were type II to type III high-tension electrical wrist burns.Free flow-through anterolateral thigh flaps(combined with great saphenous vein transplantation if necessary)were used to repair the wounds.The prognosis for all patients was good after six months to one year of follow-up.Conclusion Treating wrist types II and III high-tension electrical burns is still challenging in clinical practice.The use of free flow-through anterolateral thigh flaps(combined with great saphenous vein transplantation if necessary)to repair the wound and to restore the blood supply for the hand at the same time is a good choice for treating severe wrist electrical burns.

Descriptive epidemiological study of burn admissions to the Burns Intensive Care Unit of the Komfo Anokye Teaching Hospital, Kumasi-Ghana, 2009–2016

Objective: To determine the trends in burn admissions, and aetiology, severity and mortality of patients admitted to the Burns Intensive Care Unit of the Komfo Anokye Teaching Hospital from May 2009 to April 2016 (7 years). Methods: Patients' data used in this longitudinal and retrospective study were accessed from the records of the Reconstructive Plastic Surgery and Burns Unit. Processed data were depicted in tables and figures as appropriate. Univariate and multivariate analysis and Pearson's rank correlation were used in comparing relevant groups. Data analysis was conducted using Excel version 2013 and SPSS version 17.0. Results: A total of 681 patients, with a male to female ratio of 1.1:1.0, were analysed. The average annual incidence was 97.28 with a progressive decline in incidence. Mortality rate was 24.2%. Majority of the patients were children less than 10 years (43.5%) with scalds as the main aetiology in this group. Open flame was the major aetiology of burns (49.9%). Majority of the patients spent less than 10 days on admission (67.1%). Mean total body surface area was 30.54%. There was correlation between TBSA and disposition, total body surface area and aetiology and number of days in the Burns Intensive Care Unit, total body surface area and aetiology, and aetiology and number of days in the Burns Intensive Care Unit. Conclusions: Children below 10 years were the main victims. There was a shift from scald to open flame burns in this current study. Mean total body surface area and mortality rate have increased. There is urgent need for prevention campaign of flame burn and first aid education on intensive burns.

Changes of thromboxane and prostacyclin in the pathogenesis of multiple organ failure in severe burns

Fifty-seven severely burned patients were divided into 2 groups:16 withmultiple organ failure（MOF）,and 41 without MOF.It was found that the levelof thromboxane B2（TXB2）and the ratio between TXB2 and 6-keto-prostaglandinF1α(TBX2/6-keto-PGF1α)in plasma and in visceral tissues were increased and re-mained significantly high in the first 5～7 d postburn in patients with MOF but notso in those without MOF.The circulatory platelet aggregate ratio（CPAR）wasmarkedly decreased in the same period in MOF group.Myocardial enzymes（CPK,LDH,and GOT）were markedly increased in the first 3d and remainedsignificantly high within 7 d postburn.Degeneration,structural destruction,edema,hemorrhage and thrombosis were revealed in cardiac,pulmonary,renal andhepatic tissues succumbing to functional failure.Thirteen out of the 16 cases de-veloped MOF during the 3rd to 7th day posthurn and 11 died in that period.These findings substantiate that persistent increase of thromboxane andthromboxane/prostacyclin ratio is closely related to the origin and development ofMOF after burn injury.

Role of first day levels and subsequent trends of serum proteins in acute burns

Objective: To explore the role of first day levels and subsequent trends of serum proteins as prognostic indicators in acute burns. Methods: This prospective observational study was carried on 100 burn patients (18-60 years with 20% to 60% total burned body surface area). Serum albumin, globulin and total protein were estimated on alternate days starting from first day of burn. The first day value and the trend of serial values throughout the clinical course were compared between survivor and non-survivor groups. Results: Mean day 1 serum values of albumin, globulin, and total protein were significantly higher in the survivors compared to non-survivors (P<0.0001). Univariate logistic regression showed that increase in day one value of serum albumin, globulin and total protein by 10g /L each, significantly decreased risk of mortality by 99.4%, 98.3% and 96.6%, respectively. The serial serum values of albumin, globulin and total protein showed rising and declining trends in survivors and non-survivor respectively. Based on the ROC curve, the cut off values at any point during the course below which the prognosis was poor were 16.0 g/L, 18.0 g/L and 39.0 g/L for albumin globulin and total protein, respectively. Conclusions: The study highlights the prognostic importance of day one value and trend of serum albumin, serum globulin and total protein in acute burns. The trend of serum proteins over the course of burns should be monitored for better patient management.

A new classification of respiratory failure in severe burns

Reviewing the clinical data of 57 burn cases,the authors suggested that the postburnrespiratory failure could be classified,according to the time it occurred,into 3 types:(1)Earlytype,occurring in the shock stage with severe inhalation injury being its main cause.(2)Delayedtype,developing in the postburn acute infection stage.Its clinical course was similar to that ofadult respiratory distress syndrome,and severe shock and systemic infection were the maincauses.(3)Late type,occurring in the stages of wound healing and rehabilitation.Its etiologi.calfactors included severe hypoproteinemia,malnutrition,infection and pulmonary embolism due tothrombosis of the inferior vena cava.The new classification was proposed because it was be-lieved to be helpful in the prevention and treatment of respiratory failure in different stagespostburn.

Systemic treatment for severe concentrated sulfuric acid burns in an adult male at high altitude:A case report

BACKGROUND The aim of this study was to report a case of a patient who suffered from severe concentrated sulfuric acid burns while working at high altitude.This patient recovered after systemic treatment.We also provide a literature review for a better understanding of the disease.CASE SUMMARY A 30-year-old male,who was working in a local chemical plant in Xining at an altitude of 2261 m,suffered from 85%burns(Ⅲ°70%,deep Ⅱ°15%)after a tank containing 80%concentration of sulfuric acid exploded.The patient immediately received a series of first aid treatments,as well as rigorous wound managements after admission,which included protection for the whole body and organs,prevention and treatment of eye burns,and the appropriate oxygen therapy.After 65 d of treatment,the burn wounds had completely healed,and the patient was transferred to another specialized hospital for further eye treatment.The first aid before admission and the emergency treatment of wounds following admission were appropriate.No severe complications of sepsis,severe renal insufficiency,septic costal chondritis,corneal perforation or other burns occurred during the treatment.CONCLUSION The main causes of concentrated sulfuric acid burns consisted of accidental burns at work,accidents in the outside,factitious injuries and improper laboratory operations.The clinical manifestations were mostly deep Ⅱ°and Ⅲ°burns,with a formation of brown-black,leather-like eschar on the wound surface and locally embolized dendrite-like vessels.The clear cause of the injury and typical clinical manifestations in this case made it easy to diagnosis.However,adult cases with severe concentrated sulfuric acid burns in high altitude areas are rare,so the successful treatment of this case is of great significance.

Scald Burns in Children. An Analysis with Special Attention to the Roma Ethnic Group in East Slovakia

Objectives: A retrospective analysis of scald burns in children in a region with a significant prevalence of Roma ethnicity living in poor socioeconomic situation. Patients: During 3 year period 273 children were admitted to the Clinic of Burns and Reconstructive Surgery of our hospital;201 of them were with scald burns accounting for 73.6% of all pediatric burn admissions. More than half (58.7%) of the 201 children with scald burns were of Roma ethnicity. Results: The average BSAB of the children with scald burns was 10.8%;mean length of hospital stay 11.5 days. 58.7% of the children with scald burns was of Roma ethnicity. The non-scald admissions of children had a similar pattern but these children were older and with an even higher prevalence of Roma patients (75%), a slightly lower average BSAB (9.8%) and a significantly longer need of hospital treatment (average 15.7 days). Conclusion: The frequency of scald burn injuries in very young Roma children in our region is very high. Prevention of scald burns is possible only through targeted and well-organized education of this vulnerable population.

Prevention and treatment of gastrointestinal dysfunction following severe burns: A summary of recent 30-year clinical experience

AIM: To sum up the recent 30-year experience in the prevention and treatment of gastrointestinal dysfunction in severe burn patients, and propose practicable guidelines for the prevention and treatment of gastrointestinal (GI) dysfunction. METHODS: From 1980 to 2007, a total of 219 patients with large area and extraordinarily large area burns (LAB) were admitted, who were classified into three stages according the therapeutic protocols used at the time: Stage 1 from 1980 to 1989, stage 2 from 1990 to 1995, and stage 3 from 1996 to 2007. The occurrence and mortality of GI dysfunction in patients of the three stages were calculated and the main causes were analyzed. RESULTS: The occurrence of stress ulcer in patients with LAB was 8.6% in stage 1, which was significantly lower than that in stage 1 (P < 0.05). No massive hemorrhage from severe stress ulcer and enterogenic infections occurred in stages 2 and 3. The occurrence of abdominal distension and stress ulcer and the mortality in stage 3 patients with extraordinarily LAB was 7.1%, 21.4% and 28.5%, respectively, which were significantly lower than those in stage 1 patients(P < 0.05 or P < 0.01), and the occurrence of stress ulcer was also significantly lower than that in stage 2 patients (P < 0.05). CONCLUSION: Comprehensive fluid resuscitation, early excision of necrotic tissue, staged food ingestion, and administration of specific nutrients are essential strategies for preventing gastrointestinal complications and lowering mortality in severely burned patients.

Potentially fatal electrolyte imbalance caused by severe hydrofluoric acid burns combined with inhalation injury: A case report

BACKGROUND Hydrofluoric acid(HF)is one of the most common causes of chemical burns.HF burns can cause wounds that deepen and progress aggressively.As a result,HF burns are often severe even if they involve a small area of the skin.Published cases of HF burns have mostly reported small HF burn areas.Few cases of HF inhalation injury have been reported to date.CASE SUMMARY A 24-year-old man suffered from extensive hydrofluoric acid burns covering 60%of the total body surface area(TBSA),including deep second degree burns on 47%and third degree burns on 13%of the TBSA,after he fell into a pickling pool containing 15%HF.Comprehensive treatments were carried out after the patient was admitted.Ventricular fibrillation occurred 9 times within the first 2 h,and the lowest serum Ca2+concentration was 0.192 mmol/L.A dose of calcium gluconate(37 g)was intravenously supplied during the first 24 h,and the total amount of calcium gluconate supplementation was 343 g.Extracorporeal membrane oxygenation(ECMO)was applied for 8 d to handle the acute respiratory distress syndrome(ARDS)induced by the HF inhalation injury.The patient was discharged after 99 d of comprehensive treatment,including skin grafting.CONCLUSION Extensive HF burns combined with an inhalation injury led to a potentially fatal electrolyte imbalance and ARDS.Adequate and timely calcium supplementation and ECMO application were the keys to successful treatment of the patient.

Long-term medical treatment of patients with severe burns at exposed sites

BACKGROUND Body parts such as the face and hands are highly exposed during daily life and burns may accumulate in these areas.In addition,residual wounds,scar hyperplasia and contracture often exist in the late stage of a deep burn in these areas,which may affect patients’appearance,movements,and mental health.However,inadequate attention has been paid to this issue which can result in problems,such as difficulty in healing,possibility of carcinoma,chronic pain and a heavy mental burden.AIM To investigate the long-term medical treatment of patients with severe burns at exposed sites following a mass burn casualty event.METHODS A retrospective analysis of 13 patients with severe burns at exposed sites was performed to determine their respective long-term medical treatment.A combined wound dressing scheme consisting of traditional Chinese and Western medicine was introduced to repair residual wounds.Active and passive functional exercises with massage,Chinese herbal baths and compression fixation were proposed to ameliorate the condition of the hands.A combination of physical,chemical and photoelectrical measures was adopted for anti-scar treatment.A psychological intervention and recovery guide was provided which corresponded to the patients’psychological status.RESULTS Compared to patients who did not simultaneously receive the same treatment,patients who underwent systematic treatment recovered with a lower woundinfection rate(P<0.05),a shorter healing time(13.6±3.2 d)compared with(19.1±3.5 d)and more bearable pain during wound dressing at three days,one week and two weeks after a Chinese herbal bath(P<0.05).Satisfactory results were achieved with regard to restored function of patients’joints and blood supply to nerve endings,closure of the eyelids and the size of mouth opening tended to be normal,and only 7.1%of patients were diagnosed with severe scar hyperplasia and contracture deformity compared with 30.7%in the control group.In addition,the color,thickness,vascular distribution and softness score of the scars improved(P<0.01),and the effects of the psychological intervention was remarkable as shown by the Self-Rating Anxiety Scale and Self-Rating Depression Scale.CONCLUSION A better prognosis can be achieved in patients in the late stage of a burn with active residual wound repair,limb functional exercise,anti-scar and psychological rehabilitation.

Effective administration of cranial drilling therapy in the treatment of fourth degree temporal,facial and upper limb burns at high altitude:A case report

BACKGROUND Fourth degree burns damage the full thickness of the skin and affect underlying tissues.Skin grafting after debridement is often used to cover the wounds of salvageable severe burns.A granulation wound can be formed by drilling the skull to the barrier layer to solve the problem of skull exposure.Low oxygen levels present at high altitudes aggravate ischemia and hypoxia which can negatively impact wound healing.The impaired healing in such cases can be ameliorated by hyperbaric oxygen therapy.CASE SUMMARY We describe a patient who presented with fourth degree burns to the left temporal and facial regions upon admission in December 2018.The periosteum of the skull and the deep fascia of the face were exposed.After the first stage of debridement and skin grafting,the temporal skin did not survive well.Granulation was induced by cranial drilling,and then a local flap was transferred to cover the wound.The left temporal and facial wounds were completely covered and the patient recovered well.CONCLUSION Skin grafting and flap transfer after early debridement to cover the wound and control infection were of great significance.In the later stages of the patient's treatment,survival of the skin graft and skin flap was observed.The second stage repair was performed to achieve successful skin grafting by cranial granulation.Granulation was formed by drilling the skull,and then the wound was closed,which is suitable for cases with skull exposure and wounds with poor blood supply.We consider that hyperbaric oxygen treatment and improving tissue oxygen supply were beneficial in this patient.

The Burns Menace: Antibiotics for the Fight against Burns Bacterial Infection, a Systemic Review

Burn wound infection delays wound healing, leading to varying degrees of morbidity and mortality. Various antibiotics are administered to burn patients in burn wound management. The emergence of antibiotic resistance is a menace that costs families and the country. This review seeks to expound on infections related to burn wounds, common bacteria of burn wound infections and choice of antibiotics in burns treatment. Words such as burns, wound infection, burns injury and antibiotics were put into the Google search engine. Only articles related to the subject of burns, burn wound infection and antibiotics were used to write the review. Articles obtained included case reports on burns, research articles, review articles, short notes, briefs, literatures and other articles relating to burns. We found that the choice of antibiotics in the management of burns is an issue of major concern due to the evolution of pathogens causing these infections. The challenge of antibiotic resistance still persists in burns wound management. The commonly used topical antimicrobials included silver sulphadiazine, silver nitrate solution, silver impregnated dressings and mafenide acetate. Mafenide acetate has a wide antibacterial activity and also acts against the usual wound pathogens that were identified: Pseudomonas aeruginosa and Staphylococcus aureus. The role of antibiotic resistance is of major concern. Antibiotics must be administered after culture evidence in order to reduce the chance of increasing evolution of resistant strains of bacteria.

Imaging C-Fos Gene Expression in Burns Using Lipid Coated Spion Nanoparticles

MR imaging of gene transcription is important as it should enable the non-invasive detection of mRNA alterations in disease. A range of MRI methods have been proposed for in vivo molecular imaging of cells based on the use of ultra- small super-paramagnetic iron oxide (USPIO) nanoparticles and related susceptibility weighted imaging methods. Al-though immunohistochemistry can robustly differentiate the expression of protein variants, there is currently no direct gene assay technique that is capable of differentiating established to differentiate the induction profiles of c-Fos mRNA in vivo. To visualize the differential FosB gene expression profile in vivo after burn trauma, we developed MR probes that link the T2* contrast agent [superparamagnetic iron oxide nanoparticles (SPION)] with an oligodeoxynucleotide (ODN) sequence complementary to FosB mRNA to visualize endogenous mRNA targets via in vivo hybridization. The presence of this SPION-ODN probe in cells results in localized signal reduction in T2*-weighted MR images, in which the rate of signal reduction (R2*) reflects the regional iron concentration at different stages of amphetamine (AMPH) exposure in living mouse tissue. Our aim was to produce a superior contrast agent that can be administered using sys- temic as opposed to local administration and which will target and accumulate at sites of burn injury. Specifically, we developed and evaluated a PEGylated lipid coated MR probe with ultra-small super-paramagnetic iron oxide nanoparti- cles (USPION, a T2 susceptibility agent) coated with cationic fusogenic lipids, used for cell transfection and gene de- livery and covalently linked to a phosphorothioate modified oligodeoxynucleotide (sODN) complementary to c-Fos mRNA (SPION-cFos) and used the agent to image mice with leg burns. Our study demonstrated the feasibility of monitoring burn injury using MR imaging of c-Fos transcription in vivo, in a clinically relevant mouse model of burn injury for the first time.

Clinical Effect of Comprehensive Rehabilitation Treatment for Deep Burns in Different Functional Joint Areas

Objective:To analyse the clinical effect of comprehensive rehabilitation therapy in patients with deep burns at different functional joint areas.Methods:Eighty-one patients with deep burns with different functional joint areas from April 2018 to April 2019 were divided into the conventional and rehabilitation groupings.The conventional group(n=40)received routine treatment and rehabilitation while the rehabilitation group(n=41)was given comprehensive rehabilitation treatment.Thereafter,the recovery of joint function in patients with deep burns in different areas,the combined value of clinical long-term treatment,the recovery of joint function and the score of daily living ability were calculated.Results:The total long-term effective rate of treatment,the recovery of the joint function,and the score of daily living ability of the patients with deep burns in the rehabilitation group were more favourable than those of the conventional group as demonstrated by P<0.05,the index data indicating statistical significance.Conclusion:Comprehensive rehabilitation therapy can reduce complications and improve the quality of life in patients with deep burns in different functional joint areas.

The Treatment of Partial-Thickness Burns with a Hydroconductive Wound Dressing: Clinical and Mechanistic Effects

Objectives: Edema in partial-thickness burn wounds can decrease tissue perfusion, increase tissue ischemia, and deepen the burn injury. We report the results of a clinical trial comparing the effectiveness of a hydro-conductive dressing to our standard burn dressing at removing edema fluid from partial-thickness burns and present the proposed mechanisms of action of the hydroconductive dressing. Methods: An internally controlled comparison of two wound dressings was performed on 10 patients with non-contiguous partial-thickness burns. Each patient served as his/her own control. One burn was treated with our standard burn dressing and the other with hydroconductive dressing. Dressings were weighed prior to application, removed at 24 and 48 hours, weighed, and new pre-weighed dressings applied. Weight gain of each dressing at 24 and 48 hours was determined. Statistics were applied using the Student’s paired T-test. The VAS pain scale was measured prior to, during, and after each dressing change. Results: At 24 hours, the hydroconductive dressing had increased 85.6% ± 29.3% in weight compared with 61.3% ± 32.7% for the control (P = 0.053). For the second 24 hour period, the respective numbers were statistically significantly different at 59.7% ± 23.4% vs. 34.2% ± 19.1% (P = 0.038). Averaging the weight gain over the two dressing periods demonstrated that the differences were highly statistically significant as the hydroconductive dressing increased in weight by 71.0% ± 20.3% compared with 44.5% ± 17.4% for the gauze dressing (P = 0.005). VAS scores revealed no statistical differences. Mechanisms of action included capillary, hydroconductive, and electrostatic actions. Conclusions: A hydroconductive dressing designed to draw off excessive wound fluid removes more wound edema fluid than standard burn gauze dressings.

The Hemeostatic Efficacy of ANKAFERD after Excision of Full Thickness Burns: A Comparative Experimental Study in Rats

Objective: In order to evaluate the effects of Ankaferd blood stopper (ABS) on post-excisional burn wound bleeding via monitoring early blood hemoglobin level changes and to make a comparison with a standart topical treatment, a controlled experimental study was conducted. Design and Interventions: A contact burn model of full-thickness injury with 30% TBSA was used. Following the burn injury, excisions of burned areas were done at postburn 48th hour. 24 male Spraque Dawley rats were divided into control, adrenaline, ABS-solution and ABS-pad treatment groups. In control group no treatment was done for bleeding, but the other three groups had topical treatments. Samples were taken at the begining of the study, just before and 1 hour after the burn wound excisions for measurement of haemoglobine (Hb) levels and additionally the external bleeding amounts were measured by weighing the topical pads. Measurements and main results: Baseline Hb levels of control, adrenaline, ABS-solution and ABS-pad treatment groups were 15.06 ± 0,83, 15,82 ± 0.83, 16.23 ± 1.14 and 15.16 ± 1.46 respectively. At the 48th hour of postburn injury, the Hb levels of these groups were 13.82 ± 0.58, 13.68 ± 1.26, 13.79 ± 0.90 and 13.57 ± 0.89. Mean blood loss amounts (ml) after burn wound excisions in groups were 1.44 ± 0.26, 0.65 ± 0.07, 0.53 ± 0.08 and 0.44 ± 0.09. Conclusions: ABS was found to be as effective as topical adrenaline on reducing excisional bleeding in the experimental burn injury model.

Measurements and significance of serum gastrin,plasma motilin and serum beta-endorphin in patients with severe burns

To investigate the changes and significance of serum gastrin (GAS),betaendorphin (beta-EP) and plasma motilin (MTL) in patients with severe burns.Methods Blood samples were gotten according to different timepoints from 32 admitted burned patients,and then serum GAS,beta-EP and plasma MTL were determined by radio-immuno assay (RIA).Results In patients with severe burns,serum GAS decreased significantly in early period.And at the timepoint of 8 h,it reached the lowest level.But during 9-24 h it elevated for a while,and then it reached a relatively stable level.MTL reached the highest level at the timepoint of 2 h after burning.Then at the shock stage,it was comparatively lower.And at the timepoint of 8 h after burning,it reached the lowest level,then raised persistently after reabsorption,but still lower than the normal level.At the early stage after burning,beta-EP raised,then reached the highest level at 8 h after burning.GAS and MTL decreased and beta-EP increased significantly with the increase of the burned area.However,when the burned area was over 70% of the total body surface area,there was no relationship between then.Conclusion Blood GAS,MTL and beta-EP have represented regular changes in patients with severe burns at the early stage after burning.And the painstimulus and shock are effective factors.7 refs,3 tabs.

Large-area burns with pandrug-resistant Pseudomonas aeruginosa infection and respiratory failure

Background Infection due to pandrug-resistant Pseudomonas aeruginosa （PDRPA） has become a challenge in clinical practice. The aim of this research was to summarize the treatment of large-area burns （60%-80%） with PDRPA infection and respiratory failure in our hospital over the last two years, and to explore a feasible treatment protocol for such patients.Methods We retrospectively analyzed the treatment of five patients with large-area burns accompanied by PDRPA infection and respiratory failure transferred to our hospital from burn units in hospitals in other Chinese cities from January 2008 to February 2010. Before PDRPA infection occurred, all five patients had open wounds with large areas of granulation because of the failure of surgery and dissolving of scar tissue; they had also undergone long-term administration of carbapenems. This therapy included ventilatory support, rigorous repair of wounds, and combined antibiotic therapy targeted at drug-resistance mechanisms, including carbapenems, ciprofloxacin, macrolide antibiotics and β-lactamase inhibitors.Results Four patients recovered from bums and one died after therapy.Conclusions First, compromised immunity caused by delayed healing of burn wounds in patients with large-area bums and long-term administration of carbapenems may be the important factors in the initiation and progression of PDRPA infection. Second, if targeted at drug-resistance mechanisms, combined antibiotic therapy using carbapenems,ciprofloxacin, macrolide antibiotics and β-lactamase inhibitors could effectively control PDRPA infection. Third, although patients with large-area burns suffered respiratory failure and had high risks from anesthesia and surgery, only aggressive skin grafting with ventilatory support could control the infection and save lives. Patients may not be able to tolerate a long surgical procedure, so the duration of surgery should be minimized, and the frequency of surgery increased.

Extracorporeal membrane oxygenation combined with continuous renal replacement therapy for the treatment of severe burns:current status and challenges

Severe burns often cause various systemic complications and multiple organ dysfunction syndrome,which is the main cause of death.The lungs and kidneys are vulnerable organs in patients with multiple organ dysfunction syndrome after burns.Extracorporeal membrane oxygenation(ECMO)and continuous renal replacement therapy(CRRT)have been gradually applied in clinical practice and are beneficial for severe burn patients with refractory respiratory failure or renal dysfunction.However,the literature on ECMO combined with CRRT for the treatment of severe burns is limited.Here,we focus on the current status of ECMO combined with CRRT for the treatment of severe burns and the associated challenges,including the timing of treatment,nutrition support,heparinization and wound management,catheter-related infection and drug dosing in CRRT.With the advancement of medical technology,ECMO combined with CRRT will be further optimized to improve the outcomes of patients with severe burns.
