Determinants of Transcutaneous Ear Lobe CO2 Tension (PtCO2) at 37°C During On-Pump Cardiac Surgery.
There are no available criteria for determining the optimal flow rate and mean arterial pressure level in patients undergoing cardiopulmonary bypass (CPB). Transcutaneous carbon dioxide tension (PtCO2) has been proposed for microcirculation monitoring and it could be useful for guiding hemodynamic optimization under CPB. The goal of this exploratory study was to determine the factors that influence PtCO2 variations during CPB. ⋯ The factors that influence PtCO2 during CPB cardiac surgery are PaCO2, body temperature, and mean arterial pressure. When PaCO2 is normal, a PtCO2 elevation might be explained by insufficient mean arterial pressure. Whether low PtCO2 values during CPB should trigger the administration of vasoconstrictors remains to be evaluated.

Management of LVAD Patients for Noncardiac Surgery: A Single-Institution Study.
To describe the experience regarding the perioperative management of patients with left ventricular assist devices (LVADs) who require anesthesia while undergoing noncardiac surgery (NCS) at a single medical center. ⋯ Noncardiac surgery is becoming more common in patients with LVADs. Anesthetic management of these patients outside of the cardiac operating room is limited. Patients with Heartmate II LVADs can safely undergo noncardiac surgery.
