  • Title: Calcinosis Cutis as an Unsuspecting Complication of Hyperkalemia Treatment.
    Author: Gresham LN, Alallaf J, Shah J.
    Journal: Cureus; 2021 Aug; 13(8):e17018. PubMed ID: 34522499.
    Abstract:
    Calcinosis cutis is a known but rare complication from the extravasation of intravenous calcium preparations. Calcium gluconate is a commonly used medication to prevent cardiac arrhythmias in the setting of hyperkalemia and cardiac arrest during resuscitation and life support. Extravasation of calcium gluconate may result in skin necrosis and a bullous reaction in its most severe form, which should be promptly recognized so that treatment can be provided. Pediatric patients are more susceptible to this caustic effect while cases in adults are rare. We report the case of a patient who developed bullous skin lesions with skin necrosis and eschar formation after receiving intravenous calcium gluconate for the treatment of hyperkalemia. The patient required an extensive hospital stay and multiple surgical interventions. This case demonstrates that common medications such as calcium gluconate can lead to significant adverse effects that can be mitigated with proper administration and appropriate education about adverse events.
