Medications used in paediatric intensive care by continuous infusion: Do the technical aspects of the package inserts corroborate scientific evidence?

WHAT IS KNOWN AND OBJECTIVE: Hospitalized paediatric patients are three times more likely to experience medication errors with the potential to cause harm, when they are compared to adults. The lack of research in paediatrics, difficulties that are derived as indications and the parameters of safety and effectiveness of pharmacological therapy in children. To analyse whether the technical and legal aspects of the package insert for medicines used in paediatric intensive care units (ICU) using a continuous infusion (CI) pump corroborate the recommendations of clinical protocols and legal provisions. METHODS: A documentary study, in which technical and legal information contained in the package inserts of medications commonly used via CI in neopediatric ICUs was analysed. The consultation of the medication package insert was carried out through the electronic portal of the National Health Surveillance Agency (Agência Nacional de Vigilância Sanitária - ANVISA). Information on the use of medications in the neonatal and paediatric populations via CI was sought in the medication package insert. To analyse the legal aspects, ANVISA's RDC no. 47/2009 was used. In order to compare the technical information, the Micromedex NeoFax®, Micromedex Paediatrics®, and Lexicomp® databases were consulted. RESULTS AND DISCUSSION: Of the 13 medications analysed, 46% (n = 6) had some non-compliance with RDC 47/2009. Only 46% (n = 6) of the medications are indicated for paediatric use and only the medication package insert for midazolam (7.7%) contained the information considered essential for use via CI in paediatrics. WHAT IS NEW AND CONCLUSION: This is an innovative study that identifies the weaknesses of the medication package inserts for medications used by CI in paediatric ICUs. Failure to comply with legal recommendations can make medication administration difficult and increase the probability that errors will occur; and the absence of specific technical information can make care difficult and compromise patient safety. It is important that there is supervision by regulatory agencies and the contribution of health professionals so that non-conformities are reported and corrected, to guarantee safe care for paediatric patients in intensive care.

Enfisema pulmonar congênito: relato de caso / Congenital pulmonary enphysema: case report

Introdução: O enfisema pulmonar congênito (EPC) é uma doença rara, possuindo uma incidência de 1:20-30 mil nascimentos, é mais comum no sexo masculino do que no feminino, em uma razão de 3:1 e sua etiologia permanece desconhecida. Um terço dos casos são sintomáticos ao nascer e praticamente todos são diagnosticados nos primeiros seis meses de vida. Relato de Caso: Recém-nascido (RN) do sexo masculino, evoluiu com desconforto respiratório precoce, sendo encaminhado ao centro de terapia intensiva. Após uso de continuous positive airway pressure (CPAP) e cateter nasal de oxigênio de 12 horas, resultou em bom padrão respiratório e boa saturação. Após realização de tomografia computadorizada, foi diagnosticado o EPC. Conclusão: O EPC é uma patologia rara e deve ser suspeitado em RN com desconforto respiratório, atribuindo-se importância aos vários diagnósticos diferenciais possíveis. Apesar da etiologia incerta, é de fácil diagnóstico e possui opções de manejo clínico e cirúrgico.

Introduction: Congenital pulmonary emphysema (EPC) is a rare disease, with an incidence of 1:20-30 thousand births, it is more common in males than in females, in a ratio of 3:1 and its etiology remains unknown. One third of the cases are symptomatic at birth and practically all are diagnosed in the first six months of life. Case Report: Newborn (NB) male, developed early respiratory distress, being referred to the intensive care unit. After using continuous positive airway pressure (CPAP) and a 12-hour oxygen nasal catheter, it resulted in a good breathing pattern and good saturation. After performing computed tomography, EPC was diagnosed. Conclusion: EPC is a rare pathology and should be suspected in newborns with respiratory distress, with importance being given to the various possible differential diagnoses. Despite its uncertain etiology, it is easy to diagnose and has options for clinical and surgical management.

Efficient extraction method using magnetic carbon nanotubes to analyze cocaine and benzoylecgonine in breast milk by GC/MS.

AIM: The increasing use of cocaine (COC) during breastfeeding has led to growing concern about exposure of infants. Therefore, to study this exposure, a new method to analyze COC and benzoylecgonine in breast milk was developed. METHODOLOGY: A new extraction method was used for the first time to analyze COC and its major metabolite, benzoylecgonine, in breast milk using magnetic carbon nanotubes partially doped with nitrogen. RESULTS: The calibration curves were linear in the range 5.0-180.0 ng ml-1. The limit of quantification was 5.0 ng ml-1. Coefficients of variation were between 3.2 and 13.9%. Recovery was between 89.6 and 99.2%. CONCLUSION: The proposed method is simple, efficient and suitable to determine analytes in breast milk.

Proteinose alveolar pulmonar: Relato de caso / Pulmonary alveolar proteinosis: Case report

A proteinose alveolar pulmonar (PAP) é rara e caracterizada por preenchimento alveolar com material lipoproteináceo. A proteinose alveolar é caracterizada por um alvéolo com material eosinofílico, acelular, finamente granular, com fendas de colesterol. Este relato de caso descreve um paciente do sexo masculino, 2 anos, portador de hipogamaglobulinemia. O paciente foi internado com quadro compatível com Stevens- Johnson após uso de amoxicilina e clavulanato para quadro de otite média aguda. Posteriormente, foi encaminhado à unidade de terapia intensiva devido à piora respiratória clínica e radiológica. Biópsia pulmonar: proteinose alveolar com alvéolos distendidos por material proteináceo, eosinofílico e grumoso com infiltrado linfo- histiocitário local. A proteinose alveolar pulmonar é rara e o diagnóstico correto deve ser realizado para que seja realizado tratamento adequado e acompanhamento da evolução. Deve-se atentar para complicações, especialmente infecções oportunistas.
