Raj Gupta (@dr_rajgupta) and Eric Schwenk (@ESchwenkMD) discuss the value and risks of additives used to extend analgesia with peripheral nerve blocks. Our guests for this show are Chad Brummett (@drchadb) from the University of Michigan and Brian Williams (williamsba@umpc.edu) from the University of Pittsburgh Medical Center and the VA Pittsburgh Healthcare System.
