ABSTRACT
On August 2nd, 2014, 35 patients with extremely severe burns involved in August 2nd Kunshan factory aluminum dust explosion accident, including 18 males and 17 females, aged from 21 to 50 years, were admitted to our unit. According to the patient′s condition, the rescue members divided the participants into groups according to their characteristics, and used the multi-disciplinary cooperative treatment and management mode of integrating critical care medicine, anesthesia, traditional Chinese medicine, rehabilitation, and nursing led by burn medicine. Totally 27 patients were successfully treated, with a success rate of 77.14%.
ABSTRACT
Objective@#To summarize the measures and experience in diagnosis and treatment of extremely severe burn patients with severe inhalation injury in dust explosion accident.@*Methods@#The medical records of 13 patients with extremely severe burn complicated with severe inhalation injury in August 2nd Kunshan factory aluminum dust explosion accident who were treated at the First Affiliated Hospital of Soochow University (hereinafter referred to as our hospital) on August 2nd, 2014, were retrospectively analyzed. All the patients were transferred to our hospital 3-8 hours after injury under the condition of inhalation of pure oxygen. Twelve patients underwent tracheotomy within 5 hours after admission, while 1 patient underwent tracheotomy before admission. All the patients were in ventilator-assisted respiration, with synchronized intermittent mandatory ventilation combined with positive end expiratory pressure. All the patients underwent thorax or limbs escharotomy on the second day after admission, so as to reduce the restrictive ventilatory dysfunction caused by the contraction of thorax eschar and the terminal circulation disorder caused by the contraction of limbs eschar. All the patients underwent electronic bronchoscopy within 48 hours after admission, airway secretion were cleared and airway lavage were carried out under electronic bronchoscope according to the patients′ condition, and the sputum, lavage solution, pathological tissue were collected for microbiological culture. All the patients underwent chest X-ray examination on the second day after admission and reexamination as required. Patients were all treated with a combination of broad-spectrum antibiotics early after admission to control lung and systemic infection. One patient was treated with extracorporeal membrane oxygenation for acute respiratory distress syndrome 1 week after admission.@*Results@#One patient suffered from cardiopulmonary arrest during tracheotomy, which recovered autonomous respiration and cardiac impulse after cardiopulmonary resuscitation. Three patients showed decreased pulse oxygen saturation (SpO2) within 48 hours after injury, and the SpO2 returned to normal after sputum aspiration, scab removal and lavage under electronic bronchoscope. During the course of disease, bacteria were cultured from wound exudate of 7 patients, bacteremia occurred in 10 patients, and sputum microbiological culture results of 13 patients were positive. Eight of the 13 patients in this group survived, and 5 died. One patient died 19 days after injury, and 4 patients died 33-46 days after injury. The main cause of death was multiple organ dysfunction syndrome induced by severe septic shock eventually.@*Conclusions@#For this batch of patients with extremely severe burn complicated with severe inhalation injury caused by dust explosion accident, the treatment and cure measures including early definite diagnosis and timely tracheotomy, the application of effective ventilation, the effective treatment of respiratory system complications, and rational use of antibiotics for the control of lung infection obtained quite good curative effect.
ABSTRACT
Objective@#To investigate the clinical characteristics of extremely severe burn patients complicated with severe inhalation injury caused by dust explosion.@*Methods@#The medical records of 13 extremely severe burn patients complicated with severe inhalation injury in August 2nd Kunshan factory aluminum dust explosion accident, who were admitted to the First Affiliated Hospital of Soochow University on August 2nd, 2014, were retrospectively analyzed. The following indicators were collected: (1) Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) score and Sequential Organ Failure Assessment (SOFA) score at post admission hour (PAH) 24. (2) Prognosis, death time, causes of death, and the mortality of patients with different sexes. (3) The number of times of airway electronic bronchoscopy, airway characteristics, and the corresponding onset time. (4) The number and result of microorganism culture of lesion tissue during the leukoplakia formation stage. Detection of Pseudomonas aeruginosa in patients with and without leukoplakia in airway mucosa. Fisher′s exact probability test was used to detect the mortality of patients with different sexes. Kappa test was used to detect the relevancy between leukoplakia and Pseudomonas aeruginosa.@*Results@#(1) The APACHE Ⅱ score of patients of this group at PAH 24 was (19±3) points, and the SOFA score was (12±3) points. (2) Eight patients survived, while 5 patients died, and the time of death was 19-46 (34±10) d after injury. The main cause of death was multiple organ dysfunction syndrome, which was secondary to severe infection. One of the 7 male patients and 4 of the 6 female patients died, but there was no significantly statistical difference in mortality between patients of the two sexes (P>0.05). (3) Airway electronic bronchoscopy was performed 4-25 (10±5) times among patients of this group. Hyperemia and edema were found in the airway mucosa of all the 13 patients 2-3 weeks after injury; ulcer was found in the airway mucosa of 5 patients 2-4 weeks after injury; leukoplakia was found in the airway mucosa of 7 patients 4-14 weeks after injury; granulation formed in the airway mucosa of 7 patients 10-15 weeks after injury, and airway patency was affected, which was solved after local clamping or replacement of lengthened tracheal cannula. (4) During the leukoplakia formation stage, 19 cases of microorganism culture were performed basing on airway lesion tissue, and the results were 15 cases of Pseudomonas aeruginosa, 5 cases of Acinetobacter baumannii, 2 cases of Serratia marcescens, as well as 1 case of Stenotrophomonas maltophilia, Burkholderia cepacia, and Proteus mirabilis each. Among 7 patients with airway mucosa leukoplakia, 6 patients were detected with Pseudomonas aeruginosa. Among 6 patients without airway mucosa leukoplakia, 1 patient was detected with Pseudomonas aeruginosa. The appearance of leukoplakia was consistent with the detection of Pseudomonas aeruginosa (Kappa=0.69, P<0.05).@*Conclusions@#Most of these extremely severe burn patients complicated with severe inhalation injury caused by dust explosion survived, and there was no significant gender difference in mortality. Electronic bronchoscopy showed that the early manifestations of airway mucosa were hyperemia and edema, followed by varying degrees of erosion, ulcer, leukoplakia, and granulation formation, etc. Leukoplakia may be relevant to Pseudomonas aeruginosa infection.
ABSTRACT
Objective@#To analyze effects of cooperation between physicians in department of burn surgery and department of intensive care medicine on rescue and treatment of severe mass burn patients involved in August 2nd Kunshan factory aluminum dust explosion accident.@*Methods@#On August 2nd, 2014, 15 extremely severe burn patients involved in August 2nd Kunshan factory aluminum dust explosion accident were admitted to temporary burn treatment center established in Department of Critical Care Medicine of the Second Affiliated Hospital of Soochow University. The 15 patients were equally divided into 3 groups, with 5 patients in each group. Fifteen surgeons and 30 nurses from department of burn surgery and 15 physicians and 30 nurses from department of intensive care medicine from different hospitals in China were divided into 3 groups, with 5 physicians and 10 nurses from department of burn surgery and 5 physicians and 10 nurses from department of intensive care medicine in each group. Each group of physicians and nurses were responsible for treatment of 5 patients. Treatment of patients was leaded by surgeons from department of burn surgery, who were responsible for wound dealing and operation. Physicians from department of intensive care medicine were responsible for systemic treatment and adjustment of relevant equipment's parameters. Volume of fluid infusion and urine output in shock period, severe systemic complication during period of treatment, using time and kind of antibiotics, death in 1 month after admission, length of hospital stay, and survival of patients were monitored.@*Results@#Volume of fluid infusion of 15 extremely severe burn patients within the first 24 hours post injury was 10 360-17 162 (12 998±1 811) mL, including (1.62±0.23) mL·% total body surface area (TBSA)-1·kg-1 electrolyte and colloid and (2 850±232) mL glucose, with electrolyte and colloid ratio of (1.76±0.23)∶1.00. Volume of urine output within the first 24 hours post injury was (2 384±1 242) mL, with (99±52) mL in each hour. Volume of fluid infusion of 15 extremely severe burn patients within the second 24 hours post injury was 8 720-11 616 (9 406±1 277) mL, including (1.04±0.22) mL·%TBSA-1·kg-1 electrolyte and colloid and (2 910±187) mL glucose, with electrolyte and colloid ratio of (1.53±0.31)∶1.00. Volume of urine output within the second 24 hours post injury of patients was (2 299±1 362) mL , with (108±61) mL in each hour. One patient had pulmonary infection, and 7 patients had fungal infection, and no patient had gut microbiota dysbiosis. Patients were treated with combined 2 kinds of antibiotics for 21-85 (50±16) d. No patient died within 1 month after admission. The length of hospital stay was 53-132 (98±44) d. Ten patients survived finally.@*Conclusions@#After being treated by cooperation between physicians in department of burn surgery and department of intensive care medicine, severe mass burn patients involved in August 2nd Kunshan factory aluminum dust explosion accident had hemodynamic stability and could stably experience shock period, with less complication, shorter length of hospital stay, no death within 1 month after admission, more survived patients, which can provide reference for rescue and treatment of severe mass burn patients.
ABSTRACT
Objective@#To explore experience of wound treatment of extremely severe mass burn patients involved in August 2nd Kunshan factory aluminum dust explosion accident.@*Methods@#On August 2nd, 2014, 98 extremely severe burn mass patients involved in August 2nd Kunshan factory aluminum dust explosion accident were admitted to 20 hospitals in China. The patients with complete medical record were enrolled in the study and divided into microskin graft group with 56 patients and Meek skin graft group with 42 patients. Split-thickness skin in area of residual skin were resected to repair wounds of patients in microskin graft group and Meek skin graft group by microskin grafting and Meek miniature skin grafting, respectively. The residual wound size on 28 days post injury and wound infection after skin grafting of patients in the two groups, and position of donor site of all patients were retrospectively analyzed. Data were processed with t test and chi-square test.@*Results@#The size of residual wound of patients in Meek skin graft group on 28 days post injury was (59±13)% total body surface area (TBSA), which was obviously smaller than that in microskin graft group [(70±14)%TBSA, t=4.379, P<0.05]. Twenty-nine patients in microskin graft group and 11 patients in Meek skin graft group suffered from obvious wound infection after skin grafting. Wounds of patients in two groups were repaired with residual skin around wound in head, trunk, groin, armpit, and uncommon donor sites of scrotum (4 patients), vola (10 patients), and toe or finger web (8 patients).@*Conclusions@#Meek skin graft is the first choice for wound repair of extremely severe burn mass patients, with faster wound healing, less wound infection. Uncommon donor sites of scrotum, vola, and toe or finger web can also be used for wound repair in case of lack of skin.
ABSTRACT
Objective@#To summarize the measures and experience of treatment in mass extremely severe burn patients.@*Methods@#The clinical data and treatment of 8 extremely severe burn patients in August 2 Kunshan factory aluminum dust explosion accident who were admitted in the 100th Hospital of PLA on August 2nd, 2014, were retrospectively analyzed. There were 4 males and 4 females, aging 22-45 (34±7) years, with total burn area of 55%-98% [(89±15)%] total body surface area (TBSA) and full-thickness burn area of 45%-97% [(80±21)%] TBSA. All the 8 patients were accompanied with severe shock, inhalation injury, and blast injury. According to the requirements of former PLA General Logistics Department and Nanjing Military Command, a treatment team was set up including a special medical unit and a special care unit, with Chai Jiake from the First Affiliated Hospital of PLA General Hospital as the team leader, Zheng Qingyi from the 175th Hospital of PLA (the Affiliated Dongnan Hospital of Xiamen University) as the deputy leader, the 100th Hospital of PLA as the treatment base, and burn care, respiratory, nephrology, nursing specialists from the First Affiliated Hospital of PLA General Hospital, and the burn care experts and nursing staff from the 180th Hospital of PLA, 118th Hospital of PLA, 98th Hospital of PLA, and 175th Hospital of PLA, and nurses from the 85th Hospital of PLA, 455th Hospital of PLA, 101th Hospital of PLA, 113th Hospital of PLA as team members. Treatment strategies were adopted as unified coordination by the superior, unified responsibility of team leader, division of labor and cooperation between team members, and multidisciplinary cooperation led by department of burns. With exception of one patient who received deep vein catheterization before admission, the other 7 patients were treated with deep vein catheterization 0.5 to 3.0 hours after admission to correct hypovolemic shock as soon as possible. Eight patients received tracheotomy, and 7 patients were treated with mechanical ventilation by ventilator in protective ventilation strategy with low tide volume and low volume pressure to assist breathing. Fiberoptic bronchoscopy was done one to three times for all the 8 patients to confirm airway injuries and healing status. Escharectomy and Meek dermatoplasty in the extremities of all the 8 patients were performed 3 to 6 days after injury for the first time. Escharectomy, microskin grafting, and covering of large pieces of allogeneic skin on the trunks of 4 patients were performed 11 to 16 days after injury for the second time. The broad-spectrum antibiotics were uniformly used at first time of anti-infective therapy, and then the antibiotics species were adjusted in time. The balance of internal environment was maintained and the visceral functions were protected. One special care unit was on responsibility of only one patient. Psychological intervention was performed on admission. The rehabilitative treatment was started at early stage and in company with the whole treatment.@*Results@#Acute renal injury occurred in 5 patients within 36 hours after injury and their renal function was restored to normal 4 days after injury due to active adjustment of fluid resuscitation program. No pulmonary complications, such as severe pulmonary infection and ventilator-associated pneumonia, occurred in the survived patients. One of the 8 patients died, and the other 7 patients were cured successfully. The wounds were basically healed in 2 patients in 26 or 27 days by 2 or 3 times of operation, and in 5 patients by 4 or 5 times of operation. The basic wound healing time was 26-64 (48±15) days for all the 7 patients.@*Conclusions@#Treatment strategies of unified coordination by the superior, unified responsibility of team leader, division of labor and cooperation between team members, and multidisciplinary cooperation led by department of burns are the bases to successful treatment. Correcting shock as soon as possible is the prerequisite and closing wound as soon as possible is the key to successful treatment. Comprehensive treatment measures, such as maintaining and regulating the function of viscera, improving the body immunity, and preventing and treating the complications, are the important components to successful treatment. It is emphasized that in the treatment of mass extremely severe burn patients, specialist burn treatment should always be in the dominant position, and other related disciplines may play a part in auxiliary function.
ABSTRACT
The Kunshan factory aluminum dust explosion accident in August 2nd, 2014 caused the largest number of serious burn casualties in China in the recent 30 years. With the support of the whole country and the multidisciplinary cooperation, 185 severely burned patients were rescued and treated at 20 hospitals in Jiangsu province and Shanghai with satisfactory results. The rescue and treatment of mass burn is a complicated and systematic project on account of its suddenness, uncertainty, and non-repeatability. The treatment of this explosion accident was reviewed in this paper to explore the treatment model and experience of multidisciplinary cooperation. It is worthy to ponder and explore how to face challenges and strive to improve the treatment level of mass burns.
ABSTRACT
The treatment of mass burn patients is related to social stability, life saving, and disability reducing. It is also an important opportunity to accumulate, summarize, and improve clinical rescue and treatment experience. Aiming at August 2nd Kunshan factory aluminum dust explosion, this article reviews and summarizes experience and problems about rescue reserve, first-aid system, multidisciplinary cooperation, and integration of usual time and emergent time treatment, so as to propose corresponding strategies and provide reference for the treatment of mass burn patients and critically burned patients.
ABSTRACT
Objective To summarize the treatment experience of extensive burn merging smoke inhalation acute lung injury(SIALI)in 32 early stage cases,and to provide a reference for the further improvement of success rate in early stage. Methods A total of 32 cases of extensive burn merging SIALI resulting from mine explosion that received clinical treatment and triage from November to December in 2014 were enrolled for the study. In addition,the experience of triage and prognosis(after injured in a month)to guide therapy was analyzed. Results Two of the 32 patients died from respiratory failure in shock period,after shock period(3 days after injured),19 bad sufferers were cured in the local hospital,and the oth?er 11 cases in stable condition were triaged to the nearby hospital. 1 month follow?up results showed that:patients who received therapy in local hospi?tal,one died from MODS in 3 weeks,one died from kidney failure in 4 weeks. The other 28 patients were alive. Conclusion For these patients who suffering from extensive burn merging SIALI received therapy in early stage,we should not only schedule positive anti?shock,tracheotomy,antibiot?ics,escharectomy and nutritional support or other treatments,but also face to the challenge of lacking medical resources from too more patients. Thus,we suggest to triage the wounded to nearby hospital after anti?shock treatment,so as to improve the success rate in early stage.
