Abstract

Increased numbers of adrenaline auto-injectors (AAIs) are in circulation in the UK. The rate of accidental auto-injection injuries has increased during this time. Various treatment strategies are described in the literature. We present the case of a 32-year-old, right-hand-dominant man who sustained an unintentional AAI injury to the volar aspect of his right thumb. On presentation to the emergency department, the thumb was ischaemic. There was no improvement with simple conservative measures (warm soaks). The patient was referred to our tertiary hand surgery service and a digital block using 2% lidocaine promoted reversal of ischaemia within 2 hours with no long-term sequelae. Phentolamine rescue, on standby, was not necessary in this case. In this case report, we highlight the therapeutic challenges associated with managing AAI injury and propose an evidence-based treatment algorithm to prevent risk of severe adverse outcomes such as digital necrosis.
