AbstractVasopressor medications for circulatory shock have historically been administered through central venous catheters due to concern for extravasation injury when given peripherally. However, recent studies have demonstrated the safety of peripheral administration of vasopressor medications at lower doses and for a limited duration. Peripheral use of vasopressors is appealing to both patients and providers, as obtaining central access is an invasive procedure associated with the risk of pneumothorax, bleeding, and infection. Furthermore, waiting to initiate these medications until central access is obtained can lead to delays in care. Conversely, valid concerns remain regarding the risk of tissue extravasation associated with peripheral vasopressors, which can be life and limb threatening. We discuss the guidelines and data for optimal dose, duration, intravenous line (IV) size, IV location, and nursing IV site monitoring for peripheral vasopressors. We then explore adverse events associated with peripheral vasopressors. Finally, we describe how this practice change may impact hospital medicine providers.
