Accuracy of a Simulation Algorithm for Modelling LV Contractility, Diastolic Capacitance, and Energetics Using Data Available From Common Hemodynamic Monitors and Echocardiography.
To test the hypothesis that a simulation algorithm populated with data readily available from hemodynamic monitors and echocardiography can accurately model cardiac contractility, diastolic capacitance, and energetics. ⋯ These data support the potential for clinical utility of simulation models populated with data readily available at the bedside to characterize left ventricular mechanical performance and energetics.

Randomized Controlled TrialMultilevel Thoracic Paravertebral Block Using Ropivacaine With/Without Dexmedetomidine in Video-Assisted Thoracoscopic Surgery.
Thoracic paravertebral block (TPVB) is reported to have advantages in postoperative pain management in unilateral thoracic surgeries. Previous studies have demonstrated that dexmedetomidine could be used as an adjuvant to local anesthetics, with the aim of prolonging the duration of neural blockade. However, little is known about whether such a combination could improve the quality of postoperative analgesia compared with local anesthetic only when TPVB is used for patients undergoing video-assisted thoracoscopic surgery (VATS). ⋯ Compared with ropivacaine only, the addition of dexmedetomidine, 1 μg/kg, to local anesthetic for multilevel TPVB in patients undergoing VATS prolonged the duration of postoperative analgesia and improved patient satisfaction without serious side effects when combined with postoperative intravenous nonsteroidal anti-inflammatory drug administration.
