Vilela R, Jácomo ADN, Tresoldi AT. Risk factors for central venous catheter-related infections in pediatric intensive care. Clinics. 2007;62(5):537-44. OBJECTIVES:To identify risk factors for short-term percutaneously inserted central venous catheter-related infections in children and to evaluate the accuracy of a mortality score in predicting the risk of infection. METHOD: After reviewing the charts of patients who developed catheter-related infection in a university hospital's pediatric intensive care unit, we conducted a case-controlled study with 51 pairs. Variables related to patients and to catheter insertion and use were analyzed. Risk factors were defined by logistic regression analysis. The accuracy of the Pediatric Risk of Mortality score to discriminate the risk for infection was tested using the Receiver Operating Characteristic curve. RESULTS: Infection was associated with respiratory failure, patient's length of stay, duration of tracheal intubation, insertion of catheter in the intensive care unit and parenteral nutrition. Insertion site (femoral or internal jugular) was unimportant. Multivariate logistic regression analysis identified the following variables. Risk factors included more than one catheter placement (p=0.014) and duration of catheter use (p=0.0013), and protective factors included concomitant antibiotic use (p=0.0005) and an intermittent infusion regimen followed by heparin filling compared to continuous infusion without heparin (p=0.0002). Pediatric Risk of Mortality did not discriminate the risk of infection. CONCLUSIONS: Central parenteral nutrition and central venous catheters should be withdrawn as soon as possible. Femoral vein catheterization carries a risk of infection similar to internal jugular catheterization. The Pediatric Risk of Mortality score should not be used to predict the risk of central catheter-related infections.
Objective: To determine the impact of interdisciplinary interventions on central venous catheter-related bloodstream infections rates in a Pediatric Intensive Care Unit (PICU) and on the bloodstream infection organisms.Methods: Interventional study type before-and-after. An educational program was performed and an interdisciplinary team of interventions was created. This team was formed by nurses and doctors of the PICU and of the Infection Control Committee. The interventions were composed by direct and indirect educational and procedural measures. Task-force
COVID–19 is the disease caused by SARS-COV-2 coronavirus infection (Severe acute respiratory syndrome coronavirus 2). Although its most prevalent symptoms are respiratory, there are descriptions of gastrointestinal manifestations in children, but the presentation as an acute abdomen is rare. We report the case of a 6-month-old infant who was admitted with a diagnosis of intestinal obstruction and generalized peritonitis with no apparent cause, in whom a SARS-CoV-2 rt-PCR search was positive. We have not found descriptions of similar cases in the literature so far.
OBJETIVO: A doença pneumocócica é importante problema de saúde pública e raramente há associação desta infecção com a síndrome hemolítico-urêmica (SHU) grave. O objetivo deste artigo é relatar o caso de um paciente com esta associação. DESCRIÇÃO DO CASO: Criança do sexo masculino, com 17 meses de idade, admitida no hospital com insuficiência respiratória aguda e necessitando de suporte ventilatório. O exame radiológico mostrava extensa opacidade homogênea em hemitórax direito. A hemocultura foi positiva para Streptococcus pneumoniae. Nos exames de admissão, notaram-se: hemoglobina de 6,5g/dL, 38.000 plaquetas/mm³, uréia de 79mg/dL e creatinina de 1,64mg/dL. No primeiro dia, apresentou oligoanúria e hipervolemia, necessitando de hemodiafiltração. Evoluiu com disfunção de múltiplos órgãos e óbito no sétimo dia. A necrópsia mostrou áreas extensas de necrose cortical e tubular renal, com depósito de fibrina nas arteríolas. COMENTÁRIOS: A SHU associada ao pneumococo apresenta morbidade e mortalidade elevadas. Em crianças com doença pneumocócica invasiva e acometimento hematológico ou renal grave, deve-se estar atento a esta rara complicação. Merecem investigação os seguintes aspectos relacionados à doença: a função da detecção precoce de antígenos T ativados no diagnóstico e terapêutica, o papel do fator H na patogênese, o método ideal de substituição renal e a definição do prognóstico em longo prazo.
RESUMOObjetivo: Ressaltar a importância do estridor por anel vascular em recém-nascidos.Descrição do caso: Caso 1: recém-nascido a termo do sexo feminino, com história prévia de poli-hidrâmnio, apresentou estridor na sala de parto e necessidade de intubação orotraqueal com parâmetros ventilatórios moderados. Trouxe melhora do quadro respiratório após a inserçào de cânula traqueal além do habitual, o que motivou a investigação de compressão traqueal extrínseca. Realizado diagnóstico de duplo arco aórtico, seguido de cirurgia corretiva com boa evolução. Caso 2: menina de sete meses com estridor desde o nascimento e diagnóstico prévio de laringomalácia, com diversas internações anteriores por doenças respiratórias. Na última internação, houve melhora dos sintomas após a intubação seletiva do brônquio principal direito, sugerindo compressão extrín-seca da traqueia. Após a confirmação do diagnóstico de anel vascular, foi submetida à correção cirúrgica, porém evoluiu a óbito.Comentários: O anel vascular não é a principal causa de estridor em recém-nascidos, mas deve ser considerado no diagnóstico diferencial. O baixo índice de suspeição dessa alteração leva a atrasos no tratamento e, como consequência, aumenta o risco de traqueomalácia e dismotilidade esofágica mesmo após a correção cirúrgica.Palavras-chave: recém-nascido; sons respiratórios; estenose traqueal; aorta torácica. ABSTRACT Objective:To underline the importance of vascular rings causing stridor in newborns infants.Case description: Case 1: term female newborn infant with prenatal history of polyhydramnios that presented stridor in the delivery room. She was treated with endotracheal intubation and moderate ventilator settings. She improved her respiratory distress after the insertion of the endotracheal tube deeper than usual. This fact prompted the investigation of extrinsic tracheal compression. A double aortic arch was diagnosed, which had satisfactory surgical outcome. Case 2: a seven-month old girl with stridor since birth and previous diagnosis of laryngomalacia had several hospital admissions due to respiratory distress. In her last hospital stay, she improved after a selective intubation of the right main bronchus, suggesting the presence of extrinsic tracheal compression. After the diagnosis of a vascular ring, she was submitted to the surgical correction, but she died soon after surgery.Comments: Vascular rings are not the main cause of upper airway obstruction in newborn infants but they should be considered in the differencial diagnosis. The low index of suspicion delays diagnosis and treatment and increases the risk of tracheomalacia and esophageal dysmotility, even after surgical repair.
