“…6 We did not adopt the extended sternotomy technique (mid-sternotomy incision extended to subcostal incision) described by Budrikis et al, owing to the risk of spread of infection from abdominal cavity to chest cavity. 7 Renal protective measures taken during perioperative period included maintenance of euvolemia, avoidance of hemodilution, maintenance of hemodynamics (mean arterial pressure ≥ 65 mm Hg), maintenance of adequate flow and perfusion during CPB, limiting the duration of CPB, and avoidance of nephrotoxic agents (e.g., aminoglycosides, angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, nonsteroidal anti-inflammatory agents, and contrast agents). Renal near-infrared spectroscopy monitoring would have probably been helpful for prediction of acute kidney injury caused by ischemia, but most studies related to this modality have been done on children.…”
