ABSTRACT
Objetivo: determinar el número de pacientes que desarrollaron una infección postquirúrgica, posibles agentes etiológicos y complicaciones.Métodos : se realizó un estudio retrospectivo observacional que incluye a todos los supervivientes de las cirugías electivas y de emergencia de los servicios de Cirugía I, II y III del Hospital Universitario de Caracas durante el año 2019. Los datos fueron recopilados a través de la revisión de historias médicas. 48 historias cumplieron los criterios de inclusión, en estas se analizaron distintas variables como: días de hospitalización, síntomas, resultados de laboratorio, cultivos microbiológicos y tratamientos. A partir de estas se elaboraron tablas de frecuencia y análisis bivariado (Chi-cuadrado de Pearson) con el programa IBM SPSS Statistics 26.Resultados : la prevalencia de las infecciones postoperatorias fue de 4,69% CI 95% = (2,79-7,16%) en los servicios de Cirugía (I, II y III) del hospital durante el año 2019, la mayoría ocurrieron tras cirugías de emergencia (87,50%) tales como: apendicectomías (45,83%) y colecistectomías (10,41%). Solo al 22,91% de estos pacientes se les realizó cultivo microbiológico donde se encontró:E. coli (10,50%), Enterococcus sp. y Klebsiella pneumoniae (6,24%), Morganella morganii (2,1%) y Streptococcus pneumoniae (2,1%). Conclusión : las infecciones del sitio quirúrgico siguen siendo una de las principales causas de morbi-mortalidad y aumento de la estadía hospitalaria en los servicios de cirugía, son de diversa etiología bacteriana y están mayormente asociadas a cirugías abdominales, de emergencia(AU)
Objective: to determine the number of patients that developed a surgical site infection (SSI), possible etiologic agents and complications.Methods : an observational and retrospective study that includes every patient that underwent and survived a surgical procedure at the general surgery I, II and III services at the University Hospital of Caracas between January and December 2019. The study data were collected through the review of the medical records. 48 medical records that met the inclusion criteria and different variables were analyzed, including: days of hospitalization, symptoms, laboratory results, microbiological cultures and treatments. From those variables, frequency tables and bivariate analysis (Pearson's Chi-Square) were created with the IBM SPSS Statistics 26 program.Results : the SSI prevalence was 4,69% CI 95%= (2,79-7,16%) including the three surgery services (I, II and III) at the University Hospital of Caracas during 2019. Most of these occurred after emergency surgeries (87,50%) among which stand out: appendectomy (45,83%) and cholecystectomies (10,41%). Microbiological cultures were performed only in 22,91% of these patients and the following bacteria were isolated:E. coli (10,50%), Enterococcus sp. plus Klebsiella pneumoniae (6,24%), Morganella morganii (2,1%) and Streptococcus pneumoniae (2,1%). Conclusion : Surgical Site Infection (SSI) continues to be one of the main causes of morbimortality and increased hospital stay in surgical services in the hospital. These infections have a diverse bacterial etiology and are mostly associated with abdominal or emergency surgeries(AU)

Introduction: Surgical site infections are most commonhospitals acquired infections and are an important cause ofmorbidity and mortality. The objective of our study is toconclude the causative bacteria and antimicrobial sensitivityof surgical site infections.Material and methods: A total of 275 various clinicalsamples received in Microbiology Laboratory, GovernmentMedical College, Bettiah (West Champaran) Bihar andAssociated Hospital. from March 2018 to April 2019. Atotal 101 Staphylococcus aureus isolated, were identifiedby standard biochemical methods. Antibiotic susceptibilitytesting was performed by Kirby Bauer Disc Diffusion method.Methicillin resistance was detected by using cefoxitin (30µg)disc diffusion method as per CLSI guidelines 2016.Result: Out of the 275 aerobic bacteria which were isolated,144 were gram positive cocci (52.37%) and 131 were gramnegative bacilli (47.63%). The most common pathogenfollowed by Staphylococcus aureus 101 (36.36%). Otherorganisms were Escherichia, Pseudomonas, Klebsiella,Citrobacter, Proteus, and Enterococcus. The Antimicrobialprofile of 101 Staphylococcus aureus isolates among MRSA,resistance those they were 100% sensitive to linezolidand vancomycin, with moderate sensitivity (71.14%) tocefuroxime, gentamicin and least sensitivity to (23.81%)doxycycline, (20.95%) ciprofloxacin.Conclusion: Isolation of MRSA patients and carriers in thehospitals, regular surveillance, and monitoring of antibioticsusceptibility pattern of the hospital and community of thatregion regularly and formulation of antibiotic policy may helpin reducing the treatment failures.
