Objective:To investigate the clinical effect of self-designed modified rhomboid flap in repairing rhomboid, round, and teardrop-shaped wounds on the face.Methods:A retrospective observational study was conducted. From August 2018 to April 2020, 30 patients with facial lesions admitted into Ruijin Hospital Affiliated to Shanghai Jiao Tong University School of Medicine and the People's Hospital of Jianchuan County in Yunnan province met the inclusion criteria, including 16 males and 14 females, aged 23 to 88 years. The wound area ranged from 1.0 cm×1.0 cm to 7.0 cm×5.0 cm, with 10 cases of rhomboid wounds, 12 cases of round wounds, and 8 cases of teardrop-shaped wounds. The self-designed modified rhomboid flaps were applied to repair the wounds and after that, the patients were followed up for 1 to 18 months to record the survival of flaps, wound tension, scar formation and complications after surgery.Results:No necrosis or blackening was observed at the tip of the flaps after surgery. All the flaps survived and the wounds healed well with little tension, minimal scars, and no complications.Conclusions:The self-designed modified rhomboid flap is especially suitable for facial wounds with multiple important organs, multiple anatomical subunits, and areas with large changes in soft tissue tension, which can reduce not only the rotation of the flap, but also unnecessary excision of normal skin and soft tissue.

The ideal wound dressing should have the functions of keeping wound moist and warm, preventing and treating wound infection, promoting wound healing, and so on; However there is no such ideal wound dressing in clinic. Dressings are likely to capable application to different kinds of wounds with multi-functions in the future. For the purpose of good tissue compatibility and permanent wound cover, auto- or allo- skin living cells should be integrated with biological dressings as real artificial skin by employing tissue engineering technology. Clinical application of smart dressings can enable wound management more personalized, effective, optimized, and convenient.

Since the mechanisms of scar formation are not fully understood, at least to date, there is no ideal method to prevent and treat scar after burn. In recent years, on the basis of conventional treatments, such as pressure therapy, external use of silicone gel, and intralesional injections of corticosteroids, the therapeutic approaches of fractional carbon dioxide laser treatment, injection of anti-vascular endothelial growth factor antibody, autologous fat transplantation, injection of botulinum toxin A, radiation therapy etc., have been gradually applied to treat burn scars. It is very important to select various methods individually and comprehensively according to the specific conditions of patients and scars. Meanwhile, it is necessary to continue to study and explore the possibility of targeted therapy in scar management.

The prevalence of carbapenems-resistant Klebsiella pneumoniae (CRKP) in burn wards has become one of the most troublesome issues in current management of bacterial infections.It is necessary for us to reconsider the epidemiology,risk factors and clinical characteristics of CRKP infection as well as therapeutic options.Formulating the principles of antimicrobial therapy of CRKP infection and combined antibiotics therapy and implementing appropriate dosage regimens designed by pharmacokinetic and pharmacodynamic profiles will be of importance.Common antimicrobial agents for the treatment of CRKP infection include polymyxins,tigecycline,fosfomycin,and carbapenems.Infection control measures such as contact isolation,active screening,and environmental surface disinfection must be integrated with antimicrobial stewardship to effectively curb and prevent the spread of CRKP.

Sepsis remains a major cause of death in severe burns. The effect of sepsis management is influenced by its complicated pathophysiologic changes. In order to improve the outcome of burn sepsis, the predisposing factor of sepsis after burn analyzed by advanced technology, the early prevention, antibiotics therapy, and combined treatment in severe burns with sepsis are discussed using the concept of holistic integrative medicine.

The incidence and mortality of infective endocarditis (IE) in patients with severe burn remain high, which are attributed to invasive procedures, bacteremia, and wound infection after burns. Clinical clues for IE in burns are usually masked by burn-related manifestations, so the diagnosis of IE may be delayed or missed. For burned patients with persistent bacteremia of unknown source, especially Staphylococcus aureus-induced bacteremia, the diagnosis of IE should be considered according to the Duke criteria, and early echocardiography performance is particularly important. Antibiotic therapy is the mainstay initial management, and early surgical intervention is strongly recommended once IE is clearly diagnosed in patients with burns. In order to lower the incidence and mortality of IE in burns, it is very important to take prophylactic procedures along with the whole course of burn management.

Objective To determine the independent risk factors for sepsis in patients with large area burns.Methods The study enrolled 307 patients with large area burns treated from June 2014 to June 2015.Related variables included age,gender,visit time,emergency eschar open,burn index,tangential excision of eschar during shock stage,delayed resuscitation during shock stage,oxygen pressure(PaO2),carbon dioxide pressure (PaCO2),assisted ventilation mode,mechanical ventilation time,inhalation injury,prophylactic tracheotomy,continuous lactic acid rise,refractory hypernatremia,heart-lung disease history,and diabetes history.Correlation of the variables with the incidence of sepsis was observed.Independent predictors of sepsis in patients with large burns were differentiated using the Logistic regression analysis.Results Delayed resuscitation during shock period (OR =1.747,95％ CI 1.822-7.431,P ＜ 0.05),continuous lactic acid rise (OR =1.758,95％ CI 1.137-4.002,P ＜ 0.05),refractory hypernatremia (OR =2.985,95％ CI 1.074-6.782,P ＜ 0.05),moderate and severe inhalation injury(OR =14.764,95％ CI 0.892-47.323,P ＜ 0.05) and burn index (OR =5.017,95％ CI 1.075-23.572,P ＜ 0.05) were found be independently associated with sepsis in patients with large burns.Conclusions These independent risk factors for sepsis in large area burn patients deserve more attention.Early and timely treatment measures may reduce the incidence of sepsis.

Burn patients are facing not only their physical recovery but also some complex problems caused by the injury, including pruritus, sleep disorders, pain, and psychological disorders.These problems may bring about challenges for survivors and burn treatment team members who work with them.The purpose of this paper is to improve the understanding and knowledge of these occult problems for clinicians in this field.

The emergence and spread of carbapenems-resistant Klebsiella pneumoniae (CRKP) in burn ward is an important threat to burn management. CRKP isolates are resistant to almost all available antibiotics and are susceptible only to polymyxins and tigecycline. The mechanism of the drug resistance of CRKP is associated with the plasmid-encoded carbapenemase Klebsiella pneumoniae carbapenemase (KPC), a carbapenem-hydrolyzing β-lactamase. Antibiotics which can currently be used to treat CRKP infection include polymyxins, tigecycline, and some aminoglycosides. The efficacy of using antibiotics in combination is better than that of single-agent therapy for the treatment of CRKP infection in bloodstream. In order to control CRKP infection in burn patients, strategies for preventing CRKP dissemination in burn ward are strongly advocated.

OBJECTIVETo explore the relationship between continuous thrombocytopenia and sepsis in patients with severe burns.

METHODSClinical data of 148 severely burned patients admitted to our,two burn centers from January 2007 to December 2011 and conforming to the study criteria were retrospectively analyzed. All patients were divided into sepsis group (n =44) and non-sepsis group (n = 104) according to the presence or absence of sepsis within post burn day (PBD) 30. The data of age, gender, total burn area, full-thickness burn area, fluid infusion volume within post burn hour (PBH) 24, plasma concentration of calcium ion on PBD 1, plasma concentration of albumin on PBD 1, platelet count on PBD 1, acute physiology and chronic health evaluation (APACHE) II score on admission, the presence or absence of hypovolemic shock or inhalation injury on admission, the presence or absence of disseminated intravascular coagulation (DIC) within PBH 48, operation or no operation within PBD 3, thrombocytopenia duration within PBD 10, and mortality were statistically compared between two groups to screen the independent risk factors of sepsis. Data were processed with t test, chi-square test, single factor Logistic regression analysis, and multi-factor Logistic regression analysis.

RESULTSBetween two groups, there were statistically significant differences in total burn area, full-thickness burn area, plasma concentration of calcium ion on PBD 1, plasma concentration of albumin on PBD 1, APACHE II score on admission, presence or absence of hypovolem- ic shock on admission, presence or absence of inhalation injury on admission, presence or absence of DIC within PBH 48, and mortality (with t values from 2.433 to 4.082, χ2 values from 8. 818 to 31.528, P < 0.05 or P < 0.01). Furthermore, the duration of thrombocytopenia within PBD 10 in sepsis group was (5.2 ± 2.4) d, which was significantly longer than that in non-sepsis group [(2.9 ± 1.9) d, t =6. 189, P <0.01]. There were no statistically significant differences in the other indexes between two groups (with t values from 0.971 to 1. 250, χ2 values respectively 0. 054 and 1.529, P values above 0.05). Single factor and multi-factor Logistic regression analysis indicated that APACHE II score on admission and duration of thrombocytopenia within PBD 10 were closely related to occurrence of sepsis (with odds ratio respectively 1. 140 and 1.569, P values below 0.01).

CONCLUSIONSDuration of thrombocytopenia within PBD 10 is one of the risk factors for sepsis in severely burned patients, which can reflect pathophysiological changes in the body, thus providing predictive value for the occurrence of sepsis.
