Performance of the Hypotension Prediction Index in Living Donor Liver Transplantation

Hypotensive events during surgery and anesthesia occur frequently and are associated with complications such as myocardial infarction, acute kidney injury, and increase in mortality. Therefore predicting and preventing hypotension can lead to better outcomes.

The Hypotension Prediction Index is monitored with the Edwards Hemosphere advanced monitoring system in living donor liver transplantation recipients via the radial artery. The monitor is blinded so that the anesthesiologist cannot see the index, and the anesthesiologist manages the blood pressure according to the institution's anesthetic protocol for liver transplantation. After the surgery is done, the Hypotension Prediction Index is analyzed to see how well the index predicted actual hypotension that occured during the liver transplantation surgery. Receiver operating characteristic curves are drawn to show the performance of the Hypotension Prediction Index in liver transplantation.
