Multicenter StudyThe Use of Methadone and Ketamine for Intraoperative Pain Management in Cardiac Surgery: A Retrospective Cohort Study.
To evaluate whether the addition of ketamine to intraoperative methadone is associated with superior postoperative pain management and decreased opioid consumption compared with methadone alone in cardiac surgery patients. ⋯ Adding ketamine to methadone prolonged the time to first opioid consumption postoperatively but showed no benefits beyond POD 0. Future studies should consider protocolized dosing to optimize pain control.

Prebypass Critical Closing Pressure Predicts Acute Kidney Injury After Cardiopulmonary Bypass.
Optimal blood pressure goals during cardiopulmonary bypass (CPB) remain uncertain and new metrics to individualize perfusion targets are needed. Critical closing pressure (Pcrit) is a fundamental property of the arterial circulation related to vascular tone and represents the outflow pressure impacting flow across the systemic circulation. We examined Pcrit as a prognostic marker of acute kidney injury (AKI). ⋯ A higher prebypass Pcrit is associated with a significantly higher incidence of postoperative AKI. Future study is warranted to investigate using intraoperative Pcrit to determine a personalized blood pressure goal during CPB.
