RESUMO
OBJECTIVE: To investigate in vitro the effect of sugammadex on activated partial thromboplastin time (APTT) and prothrombin time (PT) prolongations with various anticoagulants as well as the neutralizing effect of rocuronium and vecuronium on sugammadex effects on APTT and PT. MATERIALS AND METHODS: We investigated in vitro the effect of sugammadex on APTT and/or PT in plasma of patients on a vitamin K antagonist and with elevated international normalized ratios (INRs), in plasma of healthy subjects spiked with either a low or high concentration of enoxaparin, fondaparinux, rivaroxaban, and dabigatran, and in perioperatively collected patient plasma. In addition, we explored whether the effects of sugammadex persisted in the presence of rocuronium or vecuronium, or whether they were counteracted by these compounds. RESULTS: Sugammadex concentration-dependently increased APTT and PT(INR) in all anticoagulant conditions, mainly in a proportional manner, with no differences between perioperatively collected patient and control plasma. Rocuronium and vecuronium both neutralized the effects of sugammadex on APTT and PT. CONCLUSION: Sugammadex has a transient effect on coagulation and is unlikely to increase bleeding risk, this possibility cannot be excluded for scenarios not clinically studied.
