In the theoretical part of the workshop, doctors will become familiar with the "up-to-date" changes in international recommendations in the care of vascular accesses, with methods of assessing flow during hemodialysis, but also with the preoperative examination protocol or with the rules for vascular puncture under sonographic control, focusing on "tips and tricks". In the practical part, participants will try out the discussed material in small groups. You will find all the information and the contact for registration here.
