Abstract
Rodenticides are utilized worldwide. Specific types of rodenticide exposures critical care physicians commonly encounter vary regionally. In the USA, before 1976, anticoagulant rodenticides contained warfarin. However, rodents developed resistance to warfarin, leading to the manufacture of more potent, longer lasting superwarfarins, also known as second-generation anticoagulants or long-acting anticoagulant rodenticides (LAAR). In the USA, the most common rodenticides involved in human poisonings are anticoagulant agents, specifically superwarfarin products. Annual reports of the American Association of Poison Control Centers (AAPCC) Toxic Exposure Surveillance System (TESS) reported ten deaths involving LAAR from 2002 to 2013. Superwarfarins are commonly present in homes throughout the United States, and exposure to them occurs frequently in the pediatric population [1–3]. The amount ingested is usually limited, and coagulopathy from single pediatric ingestions is rare [1–4].
