Effect of Hyperoncotic Albumin on Vascular Hemodynamics and Oxygen Delivery Following Orthotopic Liver Transplant

Phase 4
Conditions
Other Complications of Liver Transplant
Interventions
Drug: Saline
Drug: 25% albumin
Registration Number
NCT01328132
Lead Sponsor
McGill University Health Centre/Research Institute of the McGill University Health Centre
Brief Summary

The primary aim of this study is to assess the effect of hyperoncotic albumin on vascular hemodynamics and oxygen delivery after orthotopic liver transplant. The secondary aim is to try to identify the dominant physiological mechanism so that we will be able to better identify patients that may benefit from the use of albumin (25%) boluses in addition to standard care in patients following liver transplantation.

Primary Outcome Measures
NameTimeMethod
Cardiac index (CI)60 minutes after the infusion of the fluid
Secondary Outcome Measures
NameTimeMethod
Cardiac function response30 and 60 minutes after the infusion of the fluid

An improvement in Q due primarily to a change in cardiac function should have an increase in Q of ≥ 0.3 ml/min/m2/mmHg

A decrease in leak and plasma expansion30 and 60 minutes after the infusion of the fluid

A decrease in leak and plasma expansion will be determined by the Harrison formula for calculating a change in plasma volume from the change in Hb and change in Hct

Cardiac output response30 and 60 minutes after the infusion of the fluid

Cardiac output response primarily due to a "volume effect" would be expected to have an increase of CVP of a minimum of 2 mmHg and an increase in CI of \> 0.3 L/min/m2 per mmHg.

Detoxification effect of albumin30 and 60 minutes after infusion

A increase in vascular tone will be identified by an increase in systemic vascular resistance or a rise in blood pressure without a change in cardiac output or a rise in blood pressure with a fall in cardiac output
