Patient Safety: Safety of DOACs in Needle EMG
June 28, 2021
Limited data is available regarding the risk of bleeding with EMG in patients taking DOACs. One small retrospective study looked at the risk of bleeding after EMG in this patient population and in those taking warfarin, using ultrasound of studied muscles. Nine patients out of the 58 included had hemorrhagic complications, six of which were classified as clinically relevant non-major bleeding and three as asymptomatic bleeding, with a higher incidence of hemorrhage in the DOAC group as compared to the warfarin group. No cases of major bleeding were found.
