Zusammenfassung: | To describe a case of neonatal atrial flutter after the insertion of an intracardiac umbilical venous catheter, reporting the clinical presentation and reviewing the literature on this subject.
A late-preterm newborn, born at 35 weeks of gestational age to a diabetic mother and large for gestational age, with respiratory distress and rule-out sepsis, required an umbilical venous access. After the insertion of the umbilical venous catheter, the patient presented with tachycardia. Chest radiography showed that the catheter was placed in the position that corresponds to the left atrium, and traction was applied. The patient persisted with tachycardia, and an electrocardiogram showed atrial flutter. As the patient was hemodynamically unstable, electric cardioversion was successfully applied.
The association between atrial arrhythmias and misplaced umbilical catheters has been described in the literature, but in this case, it is noteworthy that the patient was an infant born to a diabetic mother, which consists in another risk factor for heart arrhythmias. Isolated atrial flutter is a rare tachyarrhythmia in the neonatal period and its identification is essential to establish early treatment and prevent systemic complications and even death.
Descrever um caso de flutter atrial neonatal após a inserção de um cateter venoso umbilical intracardíaco, relatando sua evolução clínica, e realizar uma revisão bibliográfica sobre o tema.
Recém-nascido pré-termo tardio de 35 semanas de idade gestacional, filho de mãe diabética, grande para a idade gestacional, com desconforto respiratório precoce e risco para infecção neonatal, que necessitou de cateterização venosa umbilical. Após o procedimento, o paciente apresentou taquicardia. A radiografia torácica evidenciou posição intracardíaca inadequada do cateter umbilical, que foi tracionado, e o neonato permaneceu taquicárdico. O eletrocardiograma permitiu o diagnóstico de flutter atrial. Por conta da instabilidade hemodinâmica foi realizada cardioversão elétrica, com sucesso.
A relação entre arritmias atriais e cateteres umbilicais mal posicionados tem sido descrita na literatura, mas, neste caso, vale ressaltar o fato de o paciente ser filho de mãe diabética, o que consiste em outro fator de risco para as arritmias cardíacas. O flutter atrial isolado é uma taquiarritmia rara no período neonatal, sendo o seu reconhecimento fundamental para um tratamento precoce e para evitar complicações sistêmicas e até mesmo fatais. |
