Manejo cirúrgico de ferimento auto-infligido por arma de fogo em região maxilofacial / Surgical management of self-inflicted injury by gun in the maxillofacial region

INTRODUÇÃO: O manejo dos pacientes vítimas de PAF possui vertentes divergentes a respeito do tratamento cirúrgico, que pode ser realizado de forma imedata ou tardia. Em lesões auto-infligidas, a distância entre a arma e a região acometida é menor, causando consequências estéticas e funcionais mais devastadoras. Aliado ao fato desse tipo de trauma criar uma ferida suja devido à comunicação com a cavidade oral e seios paranasais, o manejo das lesões representam um desafio mesmo à cirurgiões experientes. OBJETIVO: Estre trabalho relata o manejo cirúrgico de uma ferida auto-infligida por arma de fogo que resultou em avulsão dos tecidos moles na região maxilofacial. DESCRIÇÃO DO CASO: Paciente do sexo masculino, 35 anos, vítima de projétil de arma de fogo auto-infligido em região maxilofacial, cursando com extenso ferimento em região de língua e mento. Clinicamente, o paciente não apresentava sinais de fratura em ossos da face. Ambos os ferimentos apresentavam secreção purulenta e o paciente manifestava disfonia devido a grande destruição tecidual. CONSIDERAÇÕES FINAIS: O tratamento de ferimentos por arma de fogo não só é um grande desafio para o cirurgião, como para toda a equipe multidisciplinar requerida para tais casos, visto que não há protocolos bem definidos para o tratamento dessas lesões(AU)

INTRODUCTION: The management of patients who are victims of FAP has divergent aspects regarding surgical treatment, which can be performed immediately or late. In self-inflicted injuries, the distance between the weapon and the affected region is smaller, causing more devastating aesthetic and functional consequences. Allied to the fact that this type of trauma creates a dirty wound due to the communication with the oral cavity and paranasal sinuses, the management of injuries represents a challenge even for experienced surgeons. OBJECTIVE: This paper reports the surgical management of a self-inflicted gunshot wound that resulted in soft tissue avulsion in the maxillofacial region. CASE DESCRIPTION: Male patient, 35 years old, victim of a self-inflicted firearm projectile in the maxillofacial region, coursing with extensive injury in the region of the tongue and chin. Clinically, the patient did not show signs of facial bone fractures. Both wounds had purulent secretion and the patient had dysphonia due to extensive tissue destruction. FINAL CONSIDERATIONS: The treatment of gunshot wounds is not only a great challenge for the surgeon, but also for the entire multidisciplinary team required for such cases, since there are no well-defined protocols for the treatment of these injuries(AU)

Autologous platelet-rich plasma treatment for infected deep second-degree burn wounds: a case report / 中国输血杂志

【Objective】 To explore the feasibility of using autologous platelet-rich plasma (PRP) in the treatment of deep second-degree burns complicated with wound infection. 【Methods】 A retrospective analysis was conducted on the treatment process of a patient with deep second-degree burns and bacterial infection on the wound using autologous PRP. Clinical treatment highlights and outpatient follow-up were combined to discuss the feasibility and clinical effects of using autologous PRP in the treatment of burn wounds complicated with infection. 【Results】 The patient had a deep second-degree burn with a coagulase-negative Staphylococcus infection on the left lower limb. After one week of conventional wound dressing and antibiotic treatment, the patient's body temperature returned to normal. However, wound healing was slow and yellow secretion persisted. Subsequently, the burn wound was treated combined with topical autologous PRP. The wound pain score gradually decreased from 8 to 1. After 2 weeks, the bacterial culture of the wound secretion was negative, and the wound healed completely after 18 days. The wound scar score decreased from 5 to 2 at 1, 3 and 6 months after PRP treatment, and no obvious scar formation was observed. In the course of PRP treatment, there were no adverse reactions such as increased wound inflammation, abnormal blood routine and liver and kidney function test results. 【Conclusion】 For deep second-degree burn patients with localized wound bacterial infections who either refuse surgery or are not suitable for surgery, autologous PRP is a safer alternative that can effectively promote tissue regeneration and wound healing. The patient in this case achieved a curative effect in a short period of time.

Low-cost wound protector for laparoscopic surgeries / Protetor de ferida operatória de baixo custo para cirurgias laparoscópicas

ABSTRACT The role of wound protectors in laparoscopic surgeries is highly controversial in the literature. Some studies demonstrate their benefit in reducing the rate of surgical site infections; however, these results are not reproducible across all procedures. In addition to protecting the operative wound, these devices can be used at sites of surgical specimen extraction in laparoscopic procedures. Several commercially available devices serve this purpose but are scarcely available in resource-limited settings. One of the reasons for this limitation is the cost of the device. In this technical note, we aim to provide a cost-effective option utilizing materials readily available in the operating room and with a simple fabrication process.

RESUMO O papel dos protetores de ferida operatória em cirurgias laparoscópicas é bastante controverso na literatura. Alguns estudos demonstram seu benefício na redução da taxa de infeções de sítio cirúrgico, porém esses resultados não são reprodutíveis em todos os procedimentos. Além da proteção da ferida operatória, esses dispositivos podem ser utilizados nos sítios de extração de peças cirúrgicas em procedimentos laparoscópicos. Há vários dispositivos comercialmente disponíveis para esse fim, entretanto são pouco disponíveis nos serviços com menos recursos. Um dos motivos dessa limitação é o custo do dispositivo. Nesta nota, buscamos oferecer uma opção barata que utiliza materiais amplamente disponíveis no centro cirúrgico e cuja confecção é simples.

Microbiological profile and antibiotic sensitivity of maxillofacial infections in an emergency hospital

Aim: To investigate the bacteriological profile of oral and maxillofacial infections and the pattern of sensitivity to a specific group of antibiotics in a reference emergency hospital in Brazil. Methods: This is a prospective cohort institutional study that studied patients affected by oral and/ or maxillofacial infections in a Brazilian emergency hospital, over a 12-month period, of different etiologies, through data collection, culture and antibiogram tests, and monitoring of the process of resolution of the infectious condition. The variables were analyzed using the chi-square and Mann-Whitney tests, using a significance level of 5%. Results: The sample consisted of 61 patients, 62.3% male. The mean age of participants was 34.3 years. Odontogenic infection was the most frequent etiology and the submandibular space was the most affected. The bacterial species Streptococcus viridans was isolated in 21.6% of cases. Levofloxacin, vancomycin and penicillin were the antibiotics with the highest frequency of bacterial sensitivity, while clindamycin and erythromycin showed the highest percentages of resistance. Conclusions: The results suggest that, among the most used antibiotics for the treatment of these infections, penicillin remains an excellent option of choice for empirical therapy

Fatores de Risco para Infecção da Ferida Operatória em Pacientes Submetidos à Cirurgia Cardíaca Pediátrica / Risk Factors for Surgical Site Infection in Patients Undergoing Pediatric Cardiac Surgery

Resumo Fundamento A infecção do sítio cirúrgico (ISC) é uma importante complicação no pós-operatório de cirurgia cardíaca pediátrica associada ao aumento da morbimortalidade. Objetivos Identificar fatores de risco para a ISC após cirurgias cardíacas para correção de malformações congênitas. Métodos Este estudo caso-controle incluiu 189 pacientes com um ano completo e 19 anos e 11 meses, submetidos à cirurgia cardíaca em hospital universitário terciário de cardiologia de janeiro de 2011 a dezembro de 2018. Foi realizado registro e análise de dados pré, intra e pós-operatórios. Para cada caso foram selecionados dois controles, conforme o diagnóstico da cardiopatia e cirurgia realizada em um intervalo de até 30 dias para minimizar diferenças pré e/ou intraoperatórias. Para a análise dos fatores de risco foi utilizado o modelo de regressão binária logística. Significância estatística definida como valor de p<0,05. Resultados O estudo incluiu 66 casos e 123 controles. A incidência de ISC variou de 2% a 3,8%. Fatores de risco identificados: faixa etária de lactentes (OR 3,19, IC 95% 1,26 - 8,66, p=0,014), síndrome genética (OR 6,20, IC 95% 1,70 - 21,65, p=0,004), RACHS-1 categorias 3 e 4 (OR 8,40, IC 95% 3,30 - 21,34, p<0,001), o valor da proteína C reativa (PCR) de 48 horas pós-operatórias foi demonstrado como fator protetor para esta infecção (OR 0,85, IC 95% 0,73 - 0,98, p=0,023). Conclusão Os fatores de risco identificados não são variáveis modificáveis. Vigilância e medidas preventivas contínuas são fundamentais para reduzir a infecção. O papel do PCR elevado no pós-operatório foi fator protetor e precisa ser melhor estudado.

Abstract Background Surgical site infection is an important complication after pediatric cardiac surgery, associated with increased morbidity and mortality. Objectives We sought to identify risk factors for surgical site infection after pediatric cardiac surgeries. Methods A case-control study included patients aged between 1 year and 19 years and 11 months of age, submitted to cardiac surgery performed at a tertiary cardiac center from January 1 st , 2011, through December 31, 2018. Charts were reviewed for pre-, intra, and postoperative variables. We identified two randomly selected control patients with the same pathophysiological diagnosis and underwent surgery within thirty days of each index case. Univariate and multivariate logistic regression analyses were performed to identify risk factors. Statistical significance was defined as p<0.05. Results Sixty-six cases and 123 controls were included. Surgical site infection incidence ranged from 2% to 3.8%. The following risk factors were identified: Infant age (OR 3.19, 95% CI 1.26 to 8.66, p=0.014), presence of genetic syndrome (OR 6.20, CI 95% 1.70 to 21.65, p=0.004), categories 3 and 4 of RACHS-1 (OR 8.40, CI 95% 3.30 to 21.34, p<0.001), 48 h C-reactive protein level range was detected as a protective factor for this infection (OR 0.85, 95% CI 0.73 to 0.98, p=0.023). Conclusions The risk factors defined in this study could not be modified. Therefore, additional surveillance and new preventive strategies need to be implemented to reduce the incidence of surgical site infection. The increased CRP in the postoperative period was a protective factor that needs further understanding.

Identification of Bacterial Isolates and Their Antimicrobial Susceptibility Pattern from Wound/Pus Sample in a Tertiary Care Hospital, Gwalior, India

Objective: The goal of this investigation was to look at the frequency and dispersal of bacteria isolated from pus/wound, as well as their susceptibility patterns. Materials and Methods?A study was conducted on 175 patients who provided pus and/or wound discharge samples in different wards (outpatient department or inpatient department). MacConkey agar and blood agar plates were immediately inoculated with samples and incubated at 37°C for 24?hours. The Gram stain and biochemical tests were used to identify all isolates after incubation. Kirby–Bauer's disc diffusion method was used to perform sensitivity tests on Mueller–Hinton agar plates. Results?This study covered 175 patients, with a bacterial isolation rate of 102 (58.28%). Males outnumbered females in the samples (M:F?=?1.8:1), with a median age of 45 years as majority were in the age group of 40 to 60 years which was 41 (40.20%). Total 90.1% samples showed monomicrobial infection, whereas 9.8% showed polymicrobial infection, and total 112 bacterial strains were isolated. Conclusion?Escherichia coli was the most prevalent isolate in present investigation, followed by Pseudomonas aeruginosa. Chloramphenicol is the only antibiotic which is effective for both gram-negative bacilli and gram-positive cocci. This report's susceptibility statistic may be worth considering for developing empiric treatment regimens for pyogenic infections.

Antibacterial Activity of Lawsonia inermis Leaf Extracts against Multidrug-resistant Pseudomonas aeruginosa from Infected Wounds

Background: Wound infection comprises numerous different organisms that have the ability to surface colonization of wounds. Multidrug-resistant Pseudomonas aeruginosa is one of the pathogenic bacteria associated with wound infections. Aim: This study isolated and identified multidrug-resistant Pseudomonas aeruginosa from infected wounds and determine the antibacterial activity of Lawsonia inermis leaf extracts against it. Design: This is a Clinical and laboratory-based study involving patients with defined cases of wound infections. Place and Duration of Study: This study was conducted in the Microbiology (Bacteriology) laboratory of Specialist Hospital, Bauchi, Nigeria, from February to November 2021. Methods: Twenty-eight (28) Pseudomonas aeruginosa isolates were recovered from 179 wound swabs using standard laboratory procedures and were screened for multidrug-resistant patterns according to the Kirby-Bauer disc diffusion method. Antibacterial efficacy of the aqueous, ethanolic, and methanolic leaf extracts of Lawsonia inermis was tested against the multidrug-resistant isolates using agar well diffusion techniques. The zone of inhibition was measured and the differences between means were statistically analyzed (p<0.05). Results: A total of twenty-eight (28) multidrug-resistant Pseudomonas aeruginosa were confirmed, showing resistance to Amoxicillin (64.3%), Ceftazidime (85.71%), and Cefotaxime (78.57%) but sensitivity to Imipenem (95.5%). The phytochemical screening revealed the presence of flavonoids, glycosides, saponins, steroids, and tannins among others. MDR P. aeruginosa was inhibited at varied concentrations of the extracts with the diameter mean zone of inhibition increasing as the concentration increased. The Methanol extracts showed the highest antibacterial activity against MDR P. aeruginosa with a mean zone of inhibition of 9.500±0.288mm at 400mg/ml. Conclusion: These results indicated that Lawsonia inermis leaf extracts possess antibacterial activities on Multidrug-resistant Pseudomonas aeruginosa which could be a good source for the production of plant-based antibacterial drugs., although somewhat less than the synthetic standard drugs (Imipenem) having a mean of 13.83±0.288mm.

Removal Rate of the Tomofix® System after High Tibial Osteotomy is Higher Than Reported / A taxa de remoção do sistema Tomofix® após a osteotomia tibial alta é superior à relatada

Abstract Objective Medial open wedge high tibial osteotomy (MOWHTO) significantly relieves pain in the medial joint line in medial compartment osteoarthritis of the knee. But some patients complain of pain over the pes anserinus even 1 year after the osteotomy, which may require implant removal for relief. This study aims to define the implant removal rate after MOWHTO due to pain over the pes anserinus. Methods One hundred and three knees of 72 patients who underwent MOWHTO for medial compartment osteoarthritis between 2010 and 2018 were enrolled in the study. Knee injury and osteoarthritis outcome score (KOOS), Oxford knee score (OKS), and visual analogue score (VAS) were assessed for pain in the medial knee joint line (VAS-MJ) preoperatively, 12 months postoperatively, and yearly thereafter; adding VAS for pain over the pes anserinus (VAS-PA). Patients with VAS-PA ≥ 40 and adequate bony consolidation after 12 months were recommended implant removal. Results Thirty-three (45.8%) of the patients were male and 39 (54.2%) were female. The mean age was 49.4 ± 8.0 and the mean body mass index was 27.0 ± 2.9. The Tomofix medial tibial plate-screw system (DePuy Synthes, Raynham, MA, USA) was used in all cases. Three (2.8%) cases with delayed union requiring revision were excluded. The KOOS, OKS, and VAS-MJ significantly improved 12 months after MOWHTO. The mean VAS-PA was 38.3 ± 23.9. Implant removal for pain relief was needed in 65 (63.1%) of the103 knees. The mean VAS-PA decreased to 4.5 ± 5.6 3 months after implant removal (p < 0.0001). Conclusion Over 60% of the patients may need implant removal to relieve pain over the pes anserinus after MOWHTO. Candidates for MOWHTO should be informed about this complication and its solution.

Resumo Objetivo A osteotomia tibial alta com cunha de abertura medial (MOWHTO, do inglês medial open wedge high tibial osteotomy) alivia de forma significativa a dor na linha articular medial em casos de osteoartrite do compartimento medial do joelho. Alguns pacientes, porém, se queixam de dor nos tendões dos músculos sartório, grácil e semitendinoso (pata de ganso) mesmo 1 ano após a osteotomia, o que pode exigir a remoção do implante. Este estudo define a taxa de remoção do implante após a MOWHTO devido à dor nos tendões dos músculos sartório, grácil e semitendinoso. Métodos Cento e três joelhos de 72 pacientes submetidos à MOWHTO para tratamento da osteoartrite do compartimento medial entre 2010 e 2018 foram incluídos no estudo. A pontuação de desfecho de lesão no joelho e osteoartrite (KOOS, do inglês Knee Injury and Osteoarthritis Outcome Score), a pontuação dejoelho de Oxford (OKS, do inglês Oxford Knee Score) e a escala visual analógica (EVA) de dor na linha articular medial do joelho (EVA-MJ) foram avaliados antes da cirurgia. A EVA nos tendões dos músculos sartório, grácil e semitendinoso (EVA-PA) foi adicionada a essas avaliações, também realizadas 12 meses após o procedimento e, a seguir, anualmente. A remoção do implante foi recomendada em pacientes com EVA-PA ≥ 40 e consolidação óssea adequada em 12 meses. Resultados Trinta e três (45,8%) pacientes eram homens e 39 (54,2%), mulheres. A média de idade foi de 49,4 ±8,0, e o índice de massa corpórea (IMC) médio foi de 27,0 ± 2,9. O sistema placa-parafuso tibial medial Tomofix (DePuy Synthes, Raynham, MA, EUA) foi utilizado em todos os casos. Três (2,8%) casos foram excluídos devido ao retardo de consolidação e à necessidade de revisão. Os resultados nas escalas KOOS, OKS e EVA-MJ melhoraram significativamente 12 meses após a MOWHTO. A EVA-PA média foi de 38,3 ± 23,9. A remoção do implante para alívio da dor foi necessária em 65 (63,1%) dos 103 joelhos. Três meses após a remoção do implante, a EVA-PA média diminuiu para 4,5 ± 5,6 (p < 0,0001). Conclusão A remoção do implante pode ser necessária em mais de 60% dos pacientes para alívio da dor nos tendões dos músculos sartório, grácil e semitendinoso após a MOWHTO. Os candidatos à MOWHTO devem ser informados sobre esta complicação e sua resolução.

Preparação alcoólica para antissepsia cirúrgica das mãos / Alcoholic preparation for surgical hand antisepsy

Introdução: A infecção de sítio cirúrgico é um processo infeccioso que apresenta correlação com falhas na antissepsia cirúrgica das mãos dos profissionais da equipe cirúrgica. Objetivo: Analisar o conhecimento científico a respeito da eficácia da antissepsia cirúrgica das mãos de profissionais de saúde com preparação alcoólica em comparação com a tradicional técnica de lavagem das mãos. Material e Métodos: Revisão integrativa a partir de ensaios clínicos randomizados, estudos quase-experimentais e revisões sistemáticas (com ou sem meta-análise). O processo de busca foi realizado por um pesquisador, que utilizou os seguintes descritores e termos correlatos em português e inglês: "antissepsia" OR "desinfecção das mãos" OR "higiene das mãos" AND "controle de infecções" AND "centros cirúrgicos" OR "cirurgia". Foram consultadas as bases de dados Medical Literature Analysis and Retrievel System Online (MEDLINE/PubMed), Cochrane Database of Systematic Reviews, Literatura Latino-Americana e do Caribe em Ciências da Saúde (Lilacs) e Base de Dados de Enfermagem (BDENF). Outras fontes consultadas foram os sites da Rede Brasileira de Avaliação Tecnologias em Saúde (Rebrats), National Institute for Clinical Excellence (Nice), UpToDate, Registro Brasileiro de Ensaios Clínicos (ReBEC) e Google Acadêmico. Resultados: Os dados analisados indicaram não haver diferença estatisticamente significativa entre as taxas de infecção de sítio cirúrgico nos estudos que compararam a fricção das mãos com solução alcoólica em relação à lavagem com o comparador à base de polivinil pirrolidona iodo ou clorexidina. Conclusão: Apesar da análise dos resultados dos estudos incluídos na amostra não demonstrarem diferença estatisticamente significativa na contagem de unidades formadoras de colônias, a antissepsia cirúrgica das mãos por fricção é recomendada por apresentar fácil aplicação, menor consumo de tempo, baixos níveis de irritações cutâneas e melhor tolerância dérmica.

Introduction: Surgical site infection is an infectious process often associated with lapses in surgical hand antisepsis among healthcare professionals. This study aims to scrutinize the scientific knowledge regarding the effectiveness of surgical hand antisepsis with alcoholic preparation compared to the traditional handwashing technique. Objective: To assess available evidence through an integrative review encompassing randomized clinical trials, quasi-experimental studies, and systematic reviews, to evaluate the efficacy of surgical hand antisepsis. Materials and Methods: A comprehensive search was conducted in Medical Literature Analysis and Retrievel System Online (MEDLINE/PubMed), Cochrane Database of Systematic Reviews, Health Science Latin-American and Caribean Literature (Lilacs), and Nursing Database (BDENF) databases. Descriptors in Portuguese and English, including "antisepsis" OR "hand disinfection" OR "hand hygiene" AND "infection control," AND "surgical centers" OR "surgery," were employed. Additionally, other sources such as Rede Brasileira de Avaliação Tecnologias em Saúde (Rebrats), National Institute for Clinical Excellence (Nice), UpToDate, ReBEC, and Google Scholar were consulted. Results: The analyzed data indicated no statistically significant differences in SSI rates between studies comparing hand friction with alcoholic solution versus washing with Povidone-Iodine or chlorhexidine. Despite the absence of statistical differences in colony-forming unit counts, surgical hand antisepsis through friction is recommended due to its ease of application, shorter execution time, low levels of skin irritation, and better dermal tolerance. Conclusion: Although the results did not demonstrate a statistically significant difference in colony-forming unit counts, surgical hand antisepsis through friction is advised due to its practicality, time efficiency, low rates of skin irritation, and enhanced dermal tolerance.

Regional analgesia and surgical site infections after colorectal surgery: a retrospective cohort analysis

Abstract Background The effect of regional analgesia on perioperative infectious complications remains unknown. We therefore tested the hypothesis that a composite of serious infections after colorectal surgery is less common in patients with regional analgesia than in those given Intravenous Patient-Controlled Analgesia (IV-PCA) with opiates. Methods Patients undergoing elective colorectal surgery lasting one hour or more under general anesthesia at the Cleveland Clinic Main Campus between 2009 and 2015 were included in this retrospective analysis. Exposures were defined as regional postoperative analgesia with epidurals or Transversus Abdominis Plane blocks (TAP); or IV-PCA with opiates only. The outcome was defined as a composite of in-hospital serious infections, including intraabdominal abscess, pelvic abscess, deep or organ-space Surgical Site Infection (SSI), clostridium difficile, pneumonia, or sepsis. Logistic regression model adjusted for the imbalanced potential confounding factors among the subset of matched surgeries was used to report the odds ratios along with 95% confidence limits. The significance criterion was p < 0.05. Results A total of 7811 patients met inclusion and exclusion criteria of which we successfully matched 681 regional anesthesia patients to 2862 IV-PCA only patients based on propensity scores derived from potential confounding factors. There were 82 (12%) in-hospital postoperative serious infections in the regional analgesia group vs. 285 (10%) in IV-PCA patients. Regional analgesia was not significantly associated with serious infection (odds ratio: 1.14; 95% Confidence Interval 0.87‒1.49; p-value = 0.339) after adjusting for surgical duration and volume of intraoperative crystalloids. Conclusion Regional analgesia should not be selected as postoperative analgesic technique to reduce infections.

Distribution characteristics of pathogenic bacteria in hospitalized HIV/AIDS patients with wound infection in Yunnan / 中国热带医学

@#Abstract: Objective　To analyze the distribution characteristics of the main pathogens of HIV/AIDS patients with wound infections and provide basis for clinical diagnosis and treatment. Methods　The clinical data of 294 patients with positive secretions or pus specimens from 2016 to 2020 were analyzed retrospectively. Results　A total of 357 strains of pathogenic bacteria were isolated from 294 cases, of which 123 strains of Gram-negative bacilli (G-b), accounting for 34.5%, were mainly Escherichia coli (15.4%), Klebsiella pneumoniae (3.9%), and Pseudomonas aeruginosa (3.6%); Gram-positive bacilli (G+b) 14 strains, accounting for 3.9%; 108 Gram-positive cocci (G+c), accounting for 30.3%, of which 44 strains were coagulase-positive Staphylococcus aureus (12.3%), Coagulase-negative staphylococci were mainly Staphylococcus epidermidis (4.2%) and Staphylococcus hemolyticus (2.8%); 37 strains of fungi, accounting for 10.4%, were mainly Candida albicans (5.9%); 75 strains of Mycobacterium, accounting for 21.0%, including 41 strains of Mycobacterium tuberculosis (11.5%) and 34 strains of non-tuberculosis mycobacteria (9.5%). 52 of the 294 HIV/AIDS patients had mixed infections, accounting for 17.7%. There was significant difference in the distribution of G+c, G-b, mycobacteria and mixed infection among different specimen sources (P<0.05), and there was significant difference in the distribution of mycobacteria among different CD4+T lymphocyte counts (P<0.05). There was significant difference in the level of CD4+T lymphocytes between patients of different ages (P<0.05), and there was significant difference in the level of CD4+T lymphocytes from postoperative incision and other parts (P<0.05). Conclusions　Patients with HIV/AIDS are prone to combined wound infections with various pathogenic bacteria. We should strengthen the research on wound infection in HIV/AIDS patients, and timely send patients with a low number of CD4+T lymphocytes for secretion or pus culture, so as to carry out targeted treatment and improve the prognosis of patients.

Study on the relationship between skin cleaning status and wound infection after emergency treatment of skin wounds / 中国实用护理杂志

Objective:To analyze the relationship between skin cleaning status and wound infection after emergency treatment of skin wounds, so as to provide guidance for clinical work and home care of patients.Methods:Using retrospective research methods, a total of 349 patients with skin wounds admitted to the Department of Emergency Medicine of Lishui People′s Hospital from January 2016 to February 2022 were selected for cross-sectional investigation. And the wound-infected patients were set as the wound-infected group and the non-wound-infected patients were set as the non-wound-infected group. The patients′ clinical data, skin cleaning status and wound infection status were collected to compare the differences in the basic data between the two groups and further analyze whether there was an association between skin cleaning and wound infection using binomial Logistic regression.Results:There were 134 cases of wound infection in 349 patients with skin trauma, accounting for 38.40%, including 66 cases of acute wound infection and 68 cases of chronic wound infection.The cleaning frequency of 1 time/week, 2 times/week and ≥ 3 times/week in open wound bath cleaning was 2.99%(4/134), 0.74% (1/134) and 0 in the wound-infected group, respectively, which was significantly different from 2.79%(6/215), 7.91% (17/215) and 1.86%(4/215) in the non-wound-infected group ( χ2 = 11.42, P<0.05). Multifactorial analysis revealed that trauma area ≥8 cm 2, total cortical damage, long duration of trauma, and antibiotic treatment were independent risk factors for wound infection after emergency management of skin trauma ( OR values were 1.05-2.02, all P<0.05), the protective factors for wound infection after emergency treatment of skin trauma were bath cleaning of open wound and its cleaning times 2 times/week ( OR = 0.54, 0.62, both P<0.05). Conclusions:The choice of warm water bath cleaning after emergency treatment of skin trauma does not increase the risk of wound infection. On the contrary, it helps to prevent wound infection, but it should be noted that local disinfection should be carried out in time after the completion of cleaning.

Continuous deep irrigation combined with vacuum sealing drainage for the treatment of postoperative multidrug-resistant bacterial infections in wounds of patients with major artery injury / 中华创伤杂志

Objective:To compare the efficacy between deep continuous irrigation combined with vacuum sealing drainage (VSD) and routine dressing change in treating multidrug-resistant bacterial infections at the surgical wound site in patients with major vascular injury.Methods:A retrospective cohort study was conducted to analyze the clinical data of 28 patients with surgical wound infections by multidrug-resistant bacteria after major vascular injury treated at the First Affiliated Hospital of Henan University of Science and Technology from March 2015 to December 2021. There were 15 males and 13 females, aged 15-65 years [(41.8±12.9)years]. All patients received vascular graft surgery after major vascular injury. Postoperative microbiological culture indicated that the wound infections were caused by Carbapenem-resistant organisms (CRO) or vancomycin- resistant Enterococci (VRE), with no available sensitive antibiotics for treatment. The patients received surgical debridement every five days after vascular graft surgery and were divided into two groups to receive the subsequent treatments including a routine dressing change (routine dressing group, 14 patients) or a deep continuous irrigation combined with VSD (irrigation combined with VSD group, 14 patients). On the first day post-operation and then every 3 days, inflammatory indicators [white blood cell count, neutrophils, C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and procalcitonin] were observed in the two groups (repeat tests when a patient′s condition changed). Microbiological cultures were applied with patient samples every 5 days to observe the wound and infection control. Comparisons were made between the two groups regarding the duration to normal levels of inflammatory indicators, duration to negative CRO or VRE cultures, visual analogue score (VAS) before and at 1, 2 and 3 hours after changing the irrigation fluid (changing the dressing), conditions of wound skin grafting or flap repair, and incidences of anastomotic fistula.Results:All patients were followed up for 12-24 months [(14.3±2.4)months], during which no wound redness, rupture, purulent discharge or infection recurrence was noted. The duration to normal levels was (9.4±2.4)days for white blood cells, (9.6±2.8)days for neutrophils, (9.8±3.1)days for CRP, (12.2±3.6)days for ESR, and (7.6±1.9)days for procalcitonin in the irrigation combined with VSD group, significantly shorter than those in the routine dressing group [(15.2±3.1)days, (13.6±3.4)days, (14.2±3.9)days, (19.9±3.3)days, and (12.9±4.1)days, respectively] (all P<0.01). The duration to negative CRO or VRE cultures was (13.9±3.1)days in the irrigation combined with VSD group, significantly shorter than that in the routine dressing group [(19.2±6.9)days] ( P<0.05). The VAS before and at 1, 2 and 3 hours after changing the irrigation fluid was (4.2±0.7)points, (4.1±0.9)points, (4.2±0.9)points and (4.1±0.8)points in the irrigation combined with VSD group, respectively, and was (4.3±0.6)points, (6.9±0.7)points, (5.4±0.9)points and (4.5±0.9)points in the routine dressing group, respectively. The VAS score in the irrigation combined with VSD group was significantly lower than that in the routine dressing group at 1 hour and 2 hours after changing the irrigation fluid (all P<0.01), while no significant differences were found before and at 3 hours after changing the irrigation fluid (all P>0.05). After infection control, 5 patients (35.7%) in the irrigation combined with VSD group required skin grafting or flap repair at the wound site, lower than 11 patients (78.6%) in the routine dressing group ( P<0.01). The incidence of anastomotic fistula was 7.1% (1/14) in the irrigation combined with VSD group, lower than 42.9% (6/14) in the routine dressing group ( P<0.05). Conclusion:When multidrug-resistant bacterial infections occur at the surgical wound site after major vascular injury, deep continuous irrigation combined with VSD performs better than routine dressing change in controlling infection as well as in reducing pain, rate of wound skin grafting or flap repair and incidence of anastomotic fistula, without reliance on antibiotics.
