PiCCO GEDVI may better inform preload assessment than PAC CEDVI in cardiac surgery; hypothesis-generating and requires randomized confirmation before practice change.
Does GEDVI by PiCCO or CEDVI by PAC better correlate with transoesophageal echocardiography for assessing left ventricular preload changes after fluid replacement in cardiac surgery patients?
GEDVI assessed by the PiCCO system correlates better with echocardiographic changes in left ventricular preload following fluid replacement than CEDVI measured by a modified pulmonary artery catheter.
