Chinese Medicine Plaster as A New Treatment for Surgical Site Infection in Patients with Cesarean Delivery: A Randomized, Double-Blind, Controlled Trial / 中国结合医学杂志

OBJECTIVE@#To evaluate the efficacy of Chinese plaster containing rhubarb and mirabilite on surgical site infection (SSI) in patients with cesarean delivery (CD) by performing a randomized controlled trial.@*METHODS@#This randomized controlled trial included 560 patients with CD due to fetal head descent enrolled at a tertiary teaching center between December 31, 2018 and October 31, 2021. Eligible patients were randomly assigned to a Chinese medicine (CM) group (280 cases) or a placebo group (280 cases) by a random number table, and were treated with CM plaster (made by rhubarb and mirabilite) or a placebo plaster, respectively. Both courses of treatment lasted from the day 1 of CD, followed day 2 until discharge. The primary outcome was the total number of patients with superficial, deep and organ/space SSI. The secondary outcome was duration of postoperative hospital stay, antibiotic intake, and unplanned readmission or reoperation due to SSI. All reported efficacy and safety outcomes were confirmed by a central adjudication committee that was unaware of the study-group assignments.@*RESULTS@#During the recovery process after CD, the rates of localized swelling, redness and heat were significantly lower in the CM group than in the placebo group [7.55% (20/265) vs. 17.21% (47/274), P<0.01]. The durution of postoperative antibiotic intake was shorter in the CM group than in the placebo group (P<0.01). The duration of postoperative hospital stay was significantly shorter in the CM group than in the placebo group (5.49 ± 2.68 days vs. 8.96 ± 2.35 days, P<0.01). The rate of postoperative C-reactive protein elevation (≽100 mg/L) was lower in the CM group than in the placebo group [27.6% (73/265) vs. 43.8% (120/274), P<0.01]. However, there was no difference in purulent drainage rate from incision and superficial opening of incision between the two groups. No intestinal reactions and skin allergies were found in the CM group.@*CONCLUSIONS@#CM plaster containing rhubarb and mirabilite had an effect on SSI. It is safe for mothers and imposes lower economic and mental burdens on patients undergoing CD. (Registration No. ChiCTR2100054626).

Bowel preparation before elective surgery for colorectal cancer / 中华胃肠外科杂志

For elective surgery of colorectal cancer, current evidence supports preoperative mechanical bowel preparation combined with oral antibiotics. Meanwhile, for patients with varied degrees of intestinal stenosis, individualized protocol is required to avoid adverse events. We hereby summarize recent high-quality evidences and updates of guidelines and consensus, and recommend stratified bowel preparation based on the clinical practice of our institute as follows. (1) For patients with unimpaired oral intake, whose tumor can be passed by colonoscopy, mechanical bowel preparation and oral antibiotics are given. (2) For patients without symptoms of bowel obstruction but with impaired oral intake or incomplete colonoscopy due to tumor-related stenosis, small-dosage laxative is given for several days before surgery, and oral antibiotics the day before surgery. (3) For patients with bowel obstruction, mechanical bowel preparation or enema is not indicated. We proposed this evidence-based, individualized protocol for preoperative bowel preparation for the reference of our colleagues, in the hope of improving perioperative outcomes and reducing adverse events.

Risk factors of postoperative surgical site infection in colon cancer based on a single center database / 中华胃肠外科杂志

Objective: To explore the incidence and risk factors of postoperative surgical site infection (SSI) after colon cancer surgery. Methods: A retrospective case-control study was performed. Patients diagnosed with colon cancer who underwent radical surgery between January 2016 and May 2021 were included, and demographic characteristics, comorbidities, laboratory tests, surgical data and postoperative complications were extracted from the specialized prospective database at Department of General Surgery, Peking Union Medical College Hospital. Case exclusion criteria: (1) simultaneously multiple primary colon cancer; (2) segmental resection, subtotal colectomy, or total colectomy; (3) patients undergoing colostomy/ileostomy during the operation or in the state of colostomy/ileostomy before the operation; (4) patients receiving natural orifice specimen extraction surgery or transvaginal colon surgery; (5) patients with the history of colectomy; (6) emergency operation due to intestinal obstruction, perforation and acute bleeding; (7) intestinal diversion operation; (8) benign lesions confirmed by postoperative pathology; (9) patients not following the colorectal clinical pathway of our department for intestinal preparation and antibiotic application. Univariate analysis and multivariate analysis were used to determine the risk factors of SSI after colon cancer surgery. Results: A total of 1291 patients were enrolled in the study. 94.3% (1217/1291) of cases received laparoscopic surgery. The incidence of overall SSI was 5.3% (69/1291). According to tumor location, the incidence of SSI in the right colon, transverse colon, left colon and sigmoid colon was 8.6% (40/465), 5.2% (11/213), 7.1% (7/98) and 2.1% (11/515) respectively. According to resection range, the incidence of SSI after right hemicolectomy, transverse colectomy, left hemicolectomy and sigmoid colectomy was 8.2% (48/588), 4.5% (2/44), 4.8% (8 /167) and 2.2% (11/492) respectively. Univariate analysis showed that preoperative BUN≥7.14 mmol/L, tumor site, resection range, intestinal anastomotic approach, postoperative diarrhea, anastomotic leakage, postoperative pneumonia, and anastomotic technique were related to SSI (all P<0.05). Multivariate analysis revealed that anastomotic leakage (OR=22.074, 95%CI: 6.172-78.953, P<0.001), pneumonia (OR=4.100, 95%CI: 1.546-10.869, P=0.005), intracorporeal anastomosis (OR=5.288, 95%CI: 2.919-9.577,P<0.001) were independent risk factors of SSI. Subgroup analysis showed that in right hemicolectomy, the incidence of SSI in intracorporeal anastomosis was 19.8% (32/162), which was significantly higher than that in extracorporeal anastomosis (3.8%, 16/426, χ(2)=40.064, P<0.001). In transverse colectomy [5.0% (2/40) vs. 0, χ(2)=0.210, P=1.000], left hemicolectomy [5.4% (8/148) vs. 0, χ(2)=1.079, P=0.599] and sigmoid colectomy [2.1% (10/482) vs. 10.0% (1/10), χ(2)=2.815, P=0.204], no significant differences of SSI incidence were found between intracorporeal anastomosis and extracorporeal anastomosis (all P>0.05). Conclusions: The incidence of SSI increases with the resection range from sigmoid colectomy to right hemicolectomy. Intracorporeal anastomosis and postoperative anastomotic leakage are independent risk factors of SSI. Attentions should be paid to the possibility of postoperative pneumonia and actively effective treatment measures should be carried out.

Treatment and Chest Reconstruction for Mediastinitis Following Sternotomy for Cardiac Surgery at the Heart Institute of the University of São Paulo Medical School

Abstract This study presents the method used for chest reconstruction and treatment of mediastinitis following cardiac surgery at the Heart Institute of the University of São Paulo Medical School. After infection control with antibiotic therapy associated with aggressive surgical debridement and negative pressure wound therapy, chest reconstruction is performed using flaps. The advantages and disadvantages of negative pressure wound therapy are discussed, as well as options for flap-based chest reconstruction according to the characteristics of the patient and sternum. Further studies are needed to provide evidence to support the decisions when facing this great challenge.

Patients Submitted to Myocardial Revascularization with the Use of Bilateral Internal Thoracic Arteries: Diabetics vs. Non-Diabetics

Abstract Introduction: Use of bilateral internal thoracic artery (BITA) as graft in coronary artery bypass grafting (CABG) is controversial because it is related to higher in-hospital mortality, incidence of sternal wound-related infection, and an increase in surgical time. The primary objective of this study is to evaluate in-hospital mortality and mortality within 30 days from discharge. The secondary objective is to evaluate the occurrence of deep sternal wound infection in a 90-day follow-up. Methods: This is a retrospective review of the medical records of 152 patients undergoing elective CABG with the use of BITA and cardiopulmonary bypass (CPB). These patients were divided into two groups, diabetics and non-diabetics. Patients with acute myocardial infarction and concomitant valvular disease were not included in the sample. Results: Preoperative characteristics did not show significant differences between the groups, which allowed a comparative analysis. The variables electrocardiography time and aortic clamping time were higher in the diabetic group, with a significant statistical difference (P<0.0001). In-hospital mortality occurred in three patients, and there was no mortality up to 30 days in both groups. There was no significant difference in the primary end point between groups (P=0.56). Deep sternal wound infection was present in only one patient and showed no significant difference in the secondary outcome between groups (P=0.40). Conclusion: We did not observe a higher mortality and occurrence of deep sternal wound infection with the use of BITA in diabetic patients compared to non-diabetics, even with greater CPB and aortic clamping times in diabetics.

Infección nosocomial por Cronobacter sakazakii tras cirugía de tobillo en un paciente adulto inmunocompetente / Nosocomial Cronobacter sakazakii Infection after Ankle Surgery in an Immunocompetent Adult Patient

RESUMEN Cronobacter sakazakii es una bacteria Gram negativa que pertenece a un grupo emergente de patógenos oportunistas de la familia de los Enterococos, que causa infecciones nosocomiales. Afecta típicamente a los recién nacidos de bajo peso; puede causar graves infecciones como meningitis, sepsis o enterocolitis necrotizante, potencialmente mortales, aunque la gran mayoría de las infecciones se producen en pacientes ancianos, en los que son mucho más leves. Se reporta el primer caso confirmado de infección de herida quirúrgica en España causada por C. sakazakii en un adulto inmunocompetente(AU)

ABSTRACT Cronobacter sakazakii is a Gram negative bacterium that belongs to an emerging group of opportunistic pathogens of the Enterococci family, which causes nosocomial infections. It typically affects low birth weight newborns. It can cause serious infections such as meningitis, sepsis, or life-threatening necrotizing enterocolitis, although the vast majority of infections occur in elderly patients, where they are much milder. We report the first confirmed case of surgical wound infection in Spain, caused by C. sakazakii in an immunocompetent adult(AU)

Risk factors for multiple debridements of the patients with deep incisional surgical site infection after spinal surgery / 北京大学学报(医学版)

OBJECTIVE@#To investigate the risk factors that contribute to multiple debridements in patients suffering from deep incisional surgical site infection after spinal surgery and advise medical personnel to pay special attention to these risk factors.@*METHODS@#We retrospectively enrolled 84 patients who got deep incisional surgical site infection after spinal surgery from Jan. 2012 to Dec. 2017. The infections occurred within 30 days after the surgery, and the identification met the criteria of deep incisional surgical site infection of Centers of Disease Control (CDC). Early debridement with first stage closure of the wound and a continuous inflow-outflow irrigation system was used, and reasonable antibiotics were chosen according to the bacterial culture results. During the treatment, the vital signs, clinical manifestations, blood test results, drainage fluid colour and bacterial culture results were acquired. If the infection failed to be controlled or relapsed, a second debridement was performed. Of the 84 cases, 60 undergwent single debridement which included 36 male cases and 24 female cases, and the age ranged from 36 to 77 years, with a mean of 57.2 years. Twenty four had multiple debridements (twice in 14 cases, three times in 6 cases, four times in 1 case, five times in 2 cases, six times in 1 cases) which included 17 male cases and 7 female cases, and the age ranged from 21 to 70 years, with a mean of 49.5 years. Risk factors that predispose patients to multiple debridements were identified using univariate analysis. Risk factors with P values less than 0.05 in univariate analysis were included together in a multivariate Logistic regression model using back-forward method.@*RESULTS@#Multiple debridements were performed in 28.6% of all cases. The hospital stay of multiple debridements group was (82.4±46.3) days compared with (40.4±31.5) days in single debridement group (P=0.018). Instrumentation was removed in 6 cases in multiple debridements group and 4 cases in single debridement group (P=0.049). Flap transplantation was performed in 7 cased in multiple debridements group while none in single debridement group (P < 0.001). Diabetes, primary operation duration longer than 3 hours, primary operation blood loss more than 400 mL, bacteriology examination results, distant site infection were significantly different between the two groups in univariate analysis. In multivariate analysis, primary operation duration longer than 3 hours (OR=3.60, 95%CI: 1.12-11.62), diabetes (OR=3.74, 95%CI: 1.06-13.22), methicillin-resistant Staphylococcus aureus (MRSA) infected (OR=16.87, 95%CI: 2.59-109.73) were the most important risk factors related to multiple debridements in the patients with deep incisional surgical site infection after spinal surgery.@*CONCLUSION@#Diabetes, primary operation duration more than 3 hours, MRSA infected are independent risk factors for multiple debridements in patients suffering from deep incisional surgical site infection after spinal surgery. Special caution and prophylaxis interventions are suggested for these factors.

Silvoflurano tópico en infección superficial por SARM tras artroplastia de rodilla: caso clínico / Topical sevoflurane for superficial MRSA infection after knee arthroplasty: case report

Intentar el tratamiento retentivo de material protésico ante heridas quirúrgicas infectadas por gérmenes resistentes es objeto de debate, especialmente cuando el agente causal es un Staphylococcus aureus resistente a meticilina (SARM). Una paciente diabética y con obesidad tipo I sufrió infección de la herida quirúrgica tras artroplastia de rodilla que no evolucionó bien con antibioterapia empírica y terapia hiperosmolar. Se planificó una reintervención que fue demorada por motivos extramédicos (falta de terapia de presión negativa para cubrir la herida postoperatoria, pues se preveía no poder realizar cierre primario). Mientras se conseguía este material, y tras obtener el consentimiento de la paciente, se iniciaron irrigaciones de la herida con sevoflurano tópico off-label, pues ese fármaco ha mostrado capacidad antimicrobiana. La evolución clínica fue excelente desde el inicio a pesar de que en el cultivo se aisló un SARM resistente a la antibioterapia empírica, por lo que se desestimó la reintervención y se continuó con sevoflurano tópico junto a la antibioterapia dirigida por antibiograma, lográndose la curación completa de la herida tras 6 semanas. Durante ese tiempo, la paciente no experimentó ningún efecto adverso atribuible al sevoflurano. El sevoflurano tópico aparece como una valiosa nueva opción terapéutica ante heridas postoperatorias infectadas, especialmente cuando los gérmenes causantes son resistentes a los antibióticos convencionales.

It is challenging to try a retentive treatment of prosthetic material superinfected by resistant microorganisms, especially when the causative agent is a methicillin-resistant Staphylococcus aureus (MRSA). A diabetic, obese female patient suffered from a postoperative wound infection after a knee arthroplasty. Initial treatment with antibiotics and hyperosmolar therapy failed and clinical evolution was no good. Surgery was scheduled, but it was delayed due to nonmedical reasons (lack of negative-pressure therapy to cover the wound since primary wound closure was anticipated to be very improbable to perform). While waiting for this therapy, off-label irrigations with topical sevoflurane were started after obtaining written consent, since this drug has exhibited antimicrobial properties. Clinical evolution turned out to be excellent since the very beginning, even though a MRSA resistant to the antibiotics empirically administered was isolated. Thus, surgery was discarded, and culture-guided antibiotic therapy was added to topical sevoflurane, which was followed by a complete healing of the wound after 6 weeks. Sevoflurane treatment was well tolerated as the patient reported no adverse effects. Therefore, treating postsurgical wounds with topical sevoflurane appears as a valuable new alternative, especially when infections are caused by microorganisms resistant to conventional antibiotics.

Negative pressure wound therapy in the treatment of surgical site infection in cardiac surgery / Terapia de presión negativa en el tratamiento de la infección del sitio quirúrgico en la cirugía de corazón / Terapia por pressão negativa no tratamento de infecção do sítio cirúrgico em cirurgia cardíaca

ABSTRACT Objectives: to describe the relationship between epidemiological and clinical characteristics of postoperative cardiac surgery patients undergoing negative pressure wound therapy for the treatment of surgical site infection. Methods: an observational, cross-sectional analytical study including a convenience sample consisting of medical records of patients undergoing sternal cardiac surgery with surgical site infection diagnosed in medical records treated by negative pressure wound therapy. Results: medical records of 117 patients, mainly submitted to myocardial revascularization surgery and with deep incisional surgical site infection (88; 75.2%). Negative pressure wound therapy was used on mean for 16 (±9.5) days/patient; 1.7% had complications associated with therapy and 53.8% had discomfort, especially pain (93.6%). The duration of therapy was related to the severity of SSI (p=0.010) and the number of exchanges performed (p=0.045). Conclusions: negative pressure wound therapy has few complications, but with discomfort to patients.

Endophthalmitis after cataract surgery: results from seven years of epidemiological surveillance / Endoftalmites após cirurgia de catarata: resultado de sete anos de vigilância epidemiológica

Abstract Purpose: This study aims to describe the incidence, clinical presentation, and evolution of endophthalmitis cases occurred at an ophthalmologic center in Brazil. Methods: This is a review of medical records of patients undergoing cataract surgery from 2008 to 2014. Clinical variables associated with the outcome of postoperative endophthalmitis were evaluated. Results: during the study period, 27,609 cataract surgeries were performed. It was identified 35 cases of endophthalmitis. The overall incidence of endophthalmitis was 0.13%, with an annual variation from 0.04% to 0.27%. The main signs and symptoms in patients with endophthalmitis were ocular pain and low visual acuity associated with conjunctival hyperemia and hypopyon. Gram-positive microorganisms were the most frequent etiological agents. All patients received an intra-vitreous injection of antibiotics as immediate treatment. The final visual acuity was equal to or worse than the ability to count the examiner's fingers in 57.1% of the patients. Evisceration or enucleation was required in 3 patients. Conclusion: The incidence of endophthalmitis and the majority of signs and symptoms found in this study were in agreement with literature in the field. Although the incidence rate is low, the loss of vision experienced by most patients with endophthalmitis after cataract surgery highlights the need for efforts to prevent infection and early diagnosis to avoid such complications.

Resumo Objetivo: Descrever a incidência, a apresentação clínica e a evolução dos casos de endoftalmites ocorridos em um centro oftalmológico no Brasil. Métodos: Trata-se de uma revisão de prontuários dos pacientes submetidos à cirurgia de catarata no período de 2008 a 2014. Foram avaliadas as variáveis clínicas associadas ao desfecho de endoftalmite pós-operatória. Resultados: durante o período do estudo, foram realizadas 27.609 cirurgias de catarata. Foram identificados 35 casos de endoftalmite. A incidência global de endoftalmite foi de 0,13%, com variação anual de 0,04% a 0,27%. Os principais sinais e sintomas em pacientes com endoftalmite foram dor ocular e baixa acuidade visual associado à hiperemia conjuntival e hipópio. Os microrganismos gram-positivos foram os agentes etiológicos mais frequentes. Todos os pacientes receberam uma injeção intravítreo de antibióticos como tratamento imediato. A acuidade visual final foi igual ou pior que a capacidade de contar os dedos do examinador em 57,1% dos pacientes. Evisceração ou enucleação foi necessário em 3 pacientes. Conclusão: A incidência de endoftalmite e a maioria dos sinais e sintomas encontrados neste estudo estão de acordo com os reportados na literatura. Embora a taxa de incidência seja baixa, a perda de visão experimentada pela maioria dos pacientes com endoftalmite após a cirurgia de catarata destaca a necessidade de esforços para medidas de prevenção de infecção e diagnóstico precoce para evitar tais complicações.

Complicaciones infecciosas graves luego de la ligadura con banda elástica para hemorroides: reporte de un caso y revisión de la literatura / Acute infectious complications after ligation with elastic band for hemorrhoids: a case report and literature review

Introducción: La ligadura con banda elástica es un procedimiento efectivo y de bajo costo, para el manejo de hemorroides grado I-III, que no requiere internación. Sus complicaciones, cuando presentes, son habitualmente leves. Aunque poco comunes, existen complicaciones graves asociadas a este procedimiento. El objetivo de este estudio es realizar una revisión de las complicaciones infecciosas pelvi-perineales de la ligadura con banda elástica, características comunes de presentación y alternativas de tratamiento en aquellos que sufren estas complicaciones. Descripción del caso: Se expone el caso de un hombre de 71 años de edad que presentó una sepsis pelviana severa posterior a la realización de una ligadura con banda elástica. A las 48 horas del procedimiento consulta por dolor perianal, dificultad miccional y fiebre. Se realiza el drenaje quirúrgico de ambas fosas isquiorrectales, luego de lo cual intercurre con shock séptico, realizándose una laparotomía, drenaje de retroperitoneo, colostomía sigmoidea. Posteriormente, debido al desarrollo de un síndrome compartimental abdominal, el abdomen se dejó abierto y contenido con una malla. Discusión: Se han descripto complicaciones sépticas posteriores a escleroterapia y crioterapia hemorroidal, ligadura con banda elástica, hemorroidectomia convencional y con sutura mecánica. Se exponen 20 casos de sepsis pelviana post-ligadura con banda elástica. La relación hombre:mujer fue de 3:1, con un amplio rango de edad (27-82 años). Sólo 2 tenían antecedentes de inmunosupresión. La progresión o la persistencia del dolor asociado a fiebre, dificultad miccional, edema perineal y/o genital fueron signos y síntomas comunes que se manifestaron dentro de los 14 días posteriores a la ligadura. Tal como en el caso aquí referido como en otros ya publicados, la realización de imágenes ayudó al diagnóstico y a la planificación quirúrgica. Todos recibieron antibioticoterapia de amplio espectro y 13 requirieron además cirugía. El espectro de tratamientos quirúrgicos fue desde el drenaje incisional hasta la amputación rectal. Ante la progresión del cuadro séptico, la realización de una ostomía fue la conducta más usual. Cinco pacientes requirieron más de una cirugía, y 8 fallecieron. Conclusión: Es importante conocer las complicaciones infecciosas mayores y su presentación clínica, para realizar un diagnóstico y tratamiento precoz de las mismas, con el fin de disminuir su elevada morbilidad o mortalidad.

Background: Rubber band ligation is an effective, low-cost procedure for grade I-III hemorrhoids, and does not require hospitalization. Its complications, when present, are usually mild. Although rare, there are serious complications associated with this procedure. The purpose of this review was to identify common presenting features and treatment alternatives in those who suffer pelviperineal infectious complications after rubber band ligation. Case Report: The present case is that of a 71-year-old man who presented severe pelvic sepsis after rubber band ligation. He complained of perianal pain, voiding difficulties and fever 48 hours after the procedure. Surgical drainage of both ischiorectal fossae was carried out. He developed septic shock. Laparotomy, retroperitoneal drainage and sigmoid loop colostomy were performed. In a subsequent operation due to abdominal compartment syndrome, the abdomen was left open and contained with a mesh. Discussion: Septic complications have been described after sclerotherapy, cryotherapy, rubber band ligation, conventional hemorrhoidectomy and stapled haemorrhoidopexy. We describe 20 cases of pelvic sepsis after rubber band ligation. The male: female ratio was 3: 1, with a wide age range (27- 82 years). Only 2 had a history of immunosuppression. The progression or persistence of pain associated with fever, voiding difficulties, perineal and / or genital edema were common signs and symptoms that appeared within 14 days after rubber band ligation. In the case here referred to as in others already published, imaging studies helped the diagnosis and surgical planning. All received broad spectrum antibiotic therapy and 13 required surgery. The spectrum of surgical treatments ranged from incisional drainage to rectal amputation. In view of the progression of the septic condition, performing an ostomy was the most usual conduct. Five patients required more than one surgery, and 8 died. Conclusion: It is important to acknowledge the major infectious complications and their clinical presentation, to help with an early diagnosis and treatment, in order to reduce their high morbidity and mortality.

Surgical treatment for congenital heart defects in down syndrome patients

Abstract Objective: To analyze data related to surgical treatment in patients with congenital heart defects (CHD) and Down syndrome (DS) based on information from International Quality Improvement Collaborative Database for Congenital Heart Disease (IQIC). Methods: Between July 1, 2010 and December 31, 2017, 139 patients with CHD and DS underwent surgery at Hospital de Base and Hospital da Criança e Maternidade de São José do Rio Preto (FUNFARME)/Faculdade de Medicina de São José do Rio Preto - SP (FAMERP). A quantitative, observational and cross-sectional study was performed in which the pre, intra and postoperative data were analyzed in an IQIC database. The data included gender, age, prematurity, weight, preoperative procedures, diagnosis, associated cardiac and non-cardiac anomalies, Risk Adjustment for Congenital Heart Surgery (RACHS-1), type of surgery, cardiopulmonary bypass (CPB), perfusion time, aortic clamping time and CPB temperature, bacterial sepsis, surgical site infection and other infections, length of stay in intensive care unit (ICU), length of hospital stay and in-hospital mortality. Results: The most prevalent procedures were complete atrioventricular septal defect repair (58 - 39.45%), followed by closure of ventricular septal defect (36 - 24.49%). The RACHS-1 categories 1, 2, 3 and 4 were distributed as 22 (15%); 49 (33.3%); 72 (49%) and 4 (2.7%), respectively. There were no procedures classified as categories 5 or 6. Bacterial sepsis occurred in 10.2% of cases, surgical site infection in 6.1%, other infections in 14.3%. The median length of ICU stay was 5 days and the median length of hospital stay was 11 days. In-hospital mortality was 6.8%. Conclusion: Surgical treatment in patients with CHD and DS usually does not require highly complex surgical procedures, but are affected by infectious complications, resulting in a longer ICU and hospital length of stay with considerable mortality.

Infecção de sítio cirúrgico após cirurgia bariátrica: resultados de uma abordagem com pacote de cuidados / Surgical site infection in bariatric surgery: results of a care bundle

RESUMO Objetivo: apresentar uma análise descritiva dos resultados de um pacote de cuidados aplicado em pacientes obesos submetidos à cirurgia bariátrica, no que diz respeito ao controle de infecção. Métodos: um pacote de cuidados foi estruturado, visando a conter as taxas de infecção de sítio cirúrgico (ISC) em pacientes submetidos à cirurgia bariátrica. O pacote incluiu interrupção de tabagismo, banho com clorexidina 4% duas horas antes da cirurgia, cefazolina 2g em bolus na indução anestésica associada à administração da mesma droga com dose de 1g em infusão contínua, tricotomia apropriada, controle glicêmico, oxigênio suplementar, normotermia, controle da dor com morfina intrarraquidiana e remoção do curativo estéril 48 horas após a cirurgia. Todos os pacientes foram seguidos por 30 dias. Resultados: entre os 1.596 pacientes incluídos, 334 (20,9%) foram submetidos à cirurgia aberta e 1.262 (79,1%) à cirurgia videolaparoscópica. As taxas de ISC foram de 0,5% no grupo submetido à cirurgia laparoscópica e de 3% nos submetidos à cirurgia aberta. A incidência geral de ISC foi de 1%. Infecções intra-abdominal, do trato respiratório e do trato urinário ocorreram em 0,9%, 1,1% e 1,5% da amostra, respectivamente. Faixas mais elevadas de índice de massa corporal foram associadas a maiores incidências de ISC (p=0,001). Entre os pacientes com diabetes, 2,2% desenvolveram ISC, enquanto a taxa de infecção entre os não diabéticos foi de apenas 0,6%. Conclusão: o pacote de cuidados instituído, estruturado por estratégias centrais baseadas em evidências, associadas à medidas secundárias, foi capaz de manter baixas taxas de ISC após cirurgia bariátrica.

ABSTRACT Objective: to present a descriptive analysis of the results of a care bundle applied to obese patients submitted to bariatric surgery, regarding infection control. Methods: a care bundle was designed to control surgical site infection (SSI) rates in patients undergoing bariatric surgery. The bundle included smoking cessation, bathing with 4% chlorhexidine two hours before surgery, cefazolin (2g bolus) in anesthetic induction associated with a continuous infusion of the same drug at a dose of 1g over a two-hour period, appropriate trichotomy, glycemic control, supplemental oxygen, normothermia, intraspinal morphine for the relief of pain, and sterile dressing removal 48 hours after surgery. All patients were followed up for 30 days. Results: among the 1,596 included patients, 334 (20.9%) underwent open surgery and 1,262 (79.1%) underwent videolaparoscopic surgery. SSI rates were 0.5% in the group submitted to laparoscopic surgery and 3% in the one submitted to open surgery. The overall incidence of SSI was 1%. Intra-abdominal, respiratory tract, and urinary tract infections occurred in 0.9%, 1.1%, and 1.5% of the sample, respectively. Higher body mass index was associated with higher incidence of SSI (p=0.001). Among patients with diabetes, 2.2% developed SSI, while the rate of infection among non-diabetics was only 0.6%. Conclusion: the established care bundle, structured by core evidence-based strategies, associated with secondary measures, was able to maintain low SSI rates after bariatric surgery.

Post-surgical atypical mycobacteriosis in 125 patients in Rio de Janeiro

Abstract INTRODUCTION: The growing incidence of post-surgical atypical mycobacteriosis (PSAM) may be related to the increased use of low- and medium-complexity video-assisted surgery. METHODS: Between April 2007 and June 2009, 125 patients were referred from the State Health Department of Rio de Janeiro for the treatment of confirmed, probable, or suspected PSAM. RESULTS: Laparoscopic cholecystectomy was the most frequent surgical procedure (48.8%) among patients. Clarithromycin, ethambutol, and terizidone were used to treat 113 patients for a mean duration of 226 days. CONCLUSIONS: Despite the need for multidrug therapy and long treatment duration, most included patients adhered to treatment and experienced cure without relapse.

Infecciones asociadas a diálisis peritoneal en el paciente pediátrico: diagnóstico y tratamiento / Peritoneal dialysis-related infections in pediatric patients: diagnosis and treatment review

Resumen Las infecciones asociadas a diálisis peritoneal (DP), corresponden a la principal complicación de los pacientes pediátricos en esta terapia de reemplazo renal, disminuyendo la sobrevida de la membrana peritoneal y empeorando el pronóstico del paciente. El reconocimiento precoz y un tratamiento oportuno de éstas son fundamentales para preservar esta modalidad dialítica. Se presenta una revisión actualizada de la literatura científica, con el fin de entregar recomendaciones reproducibles en los distintos centros pediátricos que realizan diálisis peritoneal crónica en niños.

Peritoneal dialysis-related infections are the main complication in pediatric patients undergoing this renal replacement therapy, associating a high rate of morbidity, generating also a decreasing survival of the peritoneal membrane and worsening the patient outcome. We describe the recommended diagnostic and therapeutic modalities to treat dialysis-related in children.

Profilaxis antibiótica intravaginal del absceso de cúpula en histerectomía / Intravaginal antibiotic prophylaxis of dome abscess in total hysterectomy

Introducción: La histerectomía es uno de los procedimientos quirúrgicos que con más frecuencia se realiza en Ginecología. La frecuencia de aparición de absceso de cúpula varía desde un 0,7% a un 14%. La infección generalmente es polimicrobiana y los gérmenes implicados son los de la flora vaginal y endocervical de la mujer sana. En el Hospital Aeronáutico Central, desde el año 2007, además de la profilaxis intraoperatoria con cefalosporinas de primera generación, se realiza en las 12 horas previas a la cirugía programada, profilaxis con óvulos vaginales polivalentes. Objetivos: Evaluar la disminución de la incidencia de absceso de cúpula vaginal post cirugía ginecológica, que implique la manipulación de la vagina, con administración pre-quirúrgica de óvulos vaginales polivalentes. Material y Método: Estudio observacional, descriptivo y retrospectivo. Se incluyeron 220 pacientes que se les realizaron 220 histerectomías totales: 202 por vía abdominal, 5 laparoscópicas y 13 vaginales. Se realizó profilaxis intraoperatoria con cefalosporinas de 1º generación. Se les administró por vía vaginal un óvulo polivalente compuesto por: metronidazol 300 mg, miconazol nitrato 100 mg, neomicina sulfato 48,8 mg, polimixina b sulfato 4,4 mg, centella asiática 15 mg y excipientes. Se evaluó la aparición de absceso de cúpula vaginal en los 6 meses posteriores a la cirugía. Resultados: Se hallaron complicaciones post quirúrgicas en 10 pacientes (4.5%): 4 pacientes (1,8%) con infección del tracto urinario, 3 pacientes (1,4%) con infección de herida quirúrgica, 1 paciente (0,4%) con fístula vesico-vaginal, 1 paciente con Tromboembolismo pulmonar, 1 paciente con granuloma de cúpula vaginal y 1 paciente con absceso de cúpula vaginal. Esta paciente no recibió el óvulo vaginal polivalente. Conclusión: De los datos obtenidos de las 220 pacientes analizadas, y teniendo en cuenta la bibliografía consultada, podemos concluir que las pacientes que son sometidas a histerectomías totales con técnica de cúpula vaginal cerrada y que reciben como profilaxis preoperatoria un óvulo vaginal polivalente, presentan menor incidencia de complicaciones post operatorias, principalmente a nivel de la cúpula vaginal, y en particular abscesos de cúpula.

Introduction: Hysterectomy is one of the surgical procedures most frecuently performed in gynecology. Vault abscess frequency of appearance varies from 0.7% to 14%. The infection is usually polymicrobial and involved germs are those from vaginal and endocervical flora of the healthy woman. In the Hospital Aeronáutico Central, since 2007, in addition to intraoperative prophylaxis with first-generation cephalosporins, prophylaxis with polyvalent vaginal ovules is performed within 12 hours prior to scheduled surgery. Objectives: Evaluate the decrease in the incidence of vaginal vault abscess after gynecological surgery, involving the manipulation of the vagina, with pre-surgical administration of polyvalent vaginal ovules. Material and Method: Observational, descriptive and retrospective. 220 patients who underwent 220 total hysterectomies were included: 202 abdominal via, 5 laparoscopic and 13 vaginal. Intraoperative prophylaxis was performed with 1st generation cephalosporins. They were administered through vaginal via with Polyvalent ovule composed of: metronidazole 300 mg, miconazole nitrate 100 mg, neomycin sulfate 48.8 mg, polymyxin b sulfate 4.4 mg, gotu kola 15 mg and excipients. The appearance of vaginal dome abscess was evaluated in the 6 months following surgery. Results: Post-surgical complications were found in 10 patients (4.5%): 4 patients (1.8%) with urinary tract infection, 3 patients (1.4%) with surgical wound infection, 1 patient (0.4%) ) with vesico-vaginal fistula, 1 patient with pulmonary thromboembolism, 1 patient with vaginal vault granuloma and 1 patient with abscess of vaginal vault. This patient did not receive the polyvalent vaginal ovum. Conclusion: Data obtained from the 220 patients analyzed, and taking into account the bibliography consulted, we can conclude that patients who undergo total hysterectomies with a closed vaginal vault technique who receive a polyvalent vaginal ovum as a preoperative prophylaxis, present a lower incidence of post-operative complications, mainly at the level of the vaginal vault, and in particular dome abscesses

Wound natural healing in treatment of tumor-like hypertrophic scar

Abstract: Background: Surgical sutures, wound tension, additional skin incisions and other factors may result in recurrence of tumor-like scar. Objective: To investigate the role of wound natural healing therapy in tumor-like hypertrophic scar. Methods: In this study, tumor-like hypertrophic scars of 47 cases were excised completely and the residual wounds were treated with natural healing. The short-term and long-term effects of treatment were evaluated. Results: All cases were successfully cured by natural healing therapy. The healing time of the maximum wound (80mm × 20mm) and the minimal wound (5mm× 5mm) was 25 days and 7 days respectively. The size of new skin scars ranged from 3mm to 11 mm. Clinical followed-up was performed in 34 cases for 36 months. Among them, no recurrence happened in 31 cases and new scar size ranged from 2mm to 8mm, while local recurrence happened in 3 cases whose scar size were less than 5 mm. Study Limitations: The cure rate of the therapy was 91.2%. Conclusion: The wound natural healing therapy is effective in treating tumor-like hypertrophic scar, which can prevent recurrence and has good cosmetic results.

Development and validation of a stratification tool for predicting risk of deep sternal wound infection after coronary artery bypass grafting at a brazilian hospital

Abstract Objective: Deep sternal wound infection following coronary artery bypass grafting is a serious complication associated with significant morbidity and mortality. Despite the substantial impact of deep sternal wound infection, there is a lack of specific risk stratification tools to predict this complication after coronary artery bypass grafting. This study was undertaken to develop a specific prognostic scoring system for the development of deep sternal wound infection that could risk-stratify patients undergoing coronary artery bypass grafting and be applied right after the surgical procedure. Methods: Between March 2007 and August 2016, continuous, prospective surveillance data on deep sternal wound infection and a set of 27 variables of 1500 patients were collected. Using binary logistic regression analysis, we identified independent predictors of deep sternal wound infection. Initially we developed a predictive model in a subset of 500 patients. Dataset was expanded to other 1000 consecutive cases and a final model and risk score were derived. Calibration of the scores was performed using the Hosmer-Lemeshow test. Results: The model had area under Receiver Operating Characteristic (ROC) curve of 0.729 (0.821 for preliminary dataset). Baseline risk score incorporated independent predictors of deep sternal wound infection: obesity (P=0.046; OR 2.58; 95% CI 1.11-6.68), diabetes (P=0.046; OR 2.61; 95% CI 1.12-6.63), smoking (P=0.008; OR 2.10; 95% CI 1.12-4.67), pedicled internal thoracic artery (P=0.012; OR 5.11; 95% CI 1.42-18.40), and on-pump coronary artery bypass grafting (P=0.042; OR 2.20; 95% CI 1.13-5.81). A risk stratification system was, then, developed. Conclusion: This tool effectively predicts deep sternal wound infection risk at our center and may help with risk stratification in relation to public reporting and targeted prevention strategies in patients undergoing coronary artery bypass grafting.

Infecciones en cirugía bariátrica / Bariatric surgery infections

Las infecciones de sitio operatorio son eventos adversos frecuentes en cirugía, su presencia determina una mayor morbimortalidad, además de estancia hospitalaria y costos económicos para los afectados. La obesidad constituye un factor de riesgo para dicha enfermedad por aspectos multifactoriales. Considerando la epidemia occidental del sobrepeso y la obesidad, así como la masificación de la cirugía bariátrica, es importante mantener conceptos actualizados. La obesidad determina un estado de respuesta inflamatorio sistémico basal, el cual puede ser descompensado por segundas injurias, dicha descompensación puede determinar en una mayor tasa de infecciones asociadas a la intervención quirúrgica. Existe evidencia que no logra demostrar significación estadística con relación a la presencia de diabetes o H. pylori como factor de riesgo. De forma complementaria, algunos paradigmas como la mayor tasa de infecciones pulmonares o la necesidad de uso de antibiótico-profilaxis en cirugía bariátrica se mantiene.

Surgical site infections are frequent adverse events in surgery, its presence determines increased morbidity and mortality plus hospital stay and economic costs for those affected. Obesity is a risk factor for this disease by multifactorial aspects. Considering the Western epidemic overweight and obesity, as well as the massification of bariatric surgery, it is important to keep updated concepts. Obesity determines a state of basal systemic inflammatory response, which can be decompensated by a second hit, this decompensation can determine a higher rate of infections associated to surgery. There is evidence that fails to demonstrate statistical significance in relation to the presence of diabetes or H. pylori infection as a risk factor. As a complement, some paradigms as the highest rate of lung infections or the need for antibiotic prophylaxis use in bariatric surgery remains.
