Amiodarone and Adenosine for Pediatric Supraventricular Tachycardia: A Systematic Review

A review of the literature was made to find and choose research papers, on drugs (amiodarone and adenosine) used for managing supraventricular tachycardia (SVT) in children and infants (one hour to 17 years of age) with no structural heart disease by PRISMA guideline. Our team conducted an exhaustive systematic literature review (SLR), utilizing an extensive search methodology across recognized databases like PubMed, PubMed Central, Google Scholar, Web of Science, and The Cochrane Library. We included 10 scholarly articles that satisfied our rigorous selection criteria including systematic reviews/meta-analysis, and randomized control trials, shedding light on treatment with amiodarone and adenosine for SVT in pediatric patients. There is no first-or second-line treatment for SVT in pediatrics, and drug effectiveness can vary significantly between patients. Adenosine has a shorter half-life than other drugs, instead, it is safer and more valuable when an electrocardiogram is uncertain, it is recommended as an acute management, and it continues as the first-line option for paroxysmal SVT. Amiodarone management patients with acute STV within, its use showed better results when administered 48 hours after diagnosis. Furthermore, it is recommended to reduce the incidence of junctional ectopic tachycardia (JET), by pre-operative prophylaxis, also for chronic control in this and other types of SVT. In none of the evaluated studies were documented significant adverse effects in pediatric patients. Side effects that did occur were mild and easily managed. The studies also emphasize that although both amiodarone and adenosine can successfully convert SVT to sinus rhythm, better results have been observed when using combined therapies of each recommended medication. Therefore, more randomized clinical trials, meta-analyses, and systematic reviews are needed to solidify and possibly standardize an effective and safe pharmacological treatment for SVT and its types in pediatric patients.
