Agreement between radial and femoral arterial blood pressure measurements during orthotopic liver transplantation

Abstract

Objective: To study agreement between radial and femoral arterial pressure measurements in orthotopic liver transplantation (OLTx) surgery to determine whether arterial cannulation sites are interchangeable. Design, setting and participants: Prospective observational study of 25 patients undergoing OLTx surgery. Methods: Radial and femoral arteries were cannulated with standardised arterial line kits. Radial and femoral mean arterial pressure (MAP), systolic arterial pressure (SAP), diastolic arterial pressure (DAP) and pulse pressure (PP) were measured at four time points (30 minutes after induction of anaesthesia, 30 minutes after the start of the anhepatic phase, 30 minutes after liver gr..
