Complete Atrioventricular Nodal Block After Propofol Administration In An Elderly Patient Undergoing Total Knee Replacement Arthroplasty - A Case Report

Complete atrioventricular (AV) block is defined as a dissociation of atrial and ventricular activities. Complete AV block that occurs during the perioperative period is difficult to reverse and usually requires implantation of a pacemaker. Propofol does not affect a normal AV conduction system but may act as a trigger for AV block. It can also potentiate vagal stimulation factors and reduce sympathetic activity. We report a case of complete AV block that may have been related to administration of propofol.
