Adenosine is frequently used as first-line therapy for supraventricular tachycardia in both adults and children. A large bore cannula is recommended to ensure a rapid rate of delivery, as adenosine has a relatively short half-life. This may not always be considered in paediatric patients. This case concerns a 15-year-old male patient who presented to the emergency department with a fast heart rate, who had previously required repeated high doses of adenosine. The case reinforces the need for a large bore cannula when giving intravenous adenosine.
腺苷经常被用作成人和儿童的室上性心动过速的一线治疗药物。建议使用大口径套管以确保快速输送速度，因为腺苷的半衰期相对较短。在儿科患者中，这一点可能并不总是被考虑到。本病例涉及一名 15 岁男性患者，他因快速心率来到急诊室，此前曾多次需要大剂量腺苷。该病例强调了在给予静脉内腺苷时使用大口径套管的必要性。
