Conventional Ultrafiltration During Elective Cardiac Surgery and Postoperative Acute Kidney Injury.

ABSTRACT:

Objective

Conventional ultrafiltration (CUF) during cardiopulmonary bypass (CPB) serves to hemoconcentrate blood volume to avoid allogeneic blood transfusions. Previous studies have determined CUF volumes as a continuous variable are associated with postoperative acute kidney injury (AKI) after cardiac surgery, but optimal weight-indexed volumes that predict AKI have not been described.

Design

Retrospective cohort.

Setting

Single-center university hospital.

Participants

A total of 1,641 consecutive patients who underwent elective cardiac surgery between June 2013 and December 2015.

Interventions

The CUF volume was removed during CPB in all participants as part of routine practice. The authors investigated the association of dichotomized weight-indexed CU
