Case Reports
[Repeated electrical cardioversions and amiodarone for recurrent neonatal atrial flutter].
Perinatal atrial flutter is a serious arrhythmia. Its management continues to pose a challenge during the fetal period but also, in rare intractable cases, during the postnatal period. This report describes the case of a neonate who required multiple electrical external cardioversions and amiodarone to resolve a recurrent atrial flutter. This case report suggests that neonatal atrial flutter may be recurrent at short term, that repeated electrical cardioversions with low energy are safe for a neonate, that amiodarone is effective as a premedication before cardioversion and in maintaining sinus rhythm afterward, and finally that the long-term prognosis is good, even when the arrhythmia is initially refractory to therapy.

In neonates, paracetamol is mainly used for its analgesic action. This drug is actually preferred by neonatologists because of its broad therapeutic index. Recently, it has been demonstrated that paracetamol is also an anti-cyclooxygenase (COX) medication through its inhibitory action on the peroxidase arm of central and peripheral COX (Boutaud et al., 2002; Toussaint et al., 2010; Graham et al., 2013; Hinz et al., 2008; Hinz and Brune, 2011). ⋯ Indeed, recent epidemiology studies have pointed out immune deviations in children repeatedly exposed to paracetamol earlier in life. Consequently, this is actually the new discovery of an old drug. From these new data on paracetamol, a more focused pharmacovigilance on the long-term effects of paracetamol repeatedly given in the early stage should be urgently initiated.
