Randomized Controlled TrialEffect of epidural magnesium on the incidence of chronic postoperative pain after video-assisted thoracic surgery.
The aim of this study was to determine whether the epidural administration of magnesium during the perioperative period decreased the incidence of chronic postoperative pain (CPOP) at 3 months after video-assisted thoracic surgery. ⋯ The epidural administration of magnesium from before the induction of anesthesia to 48 hours postoperatively did not decrease significantly the incidence or severity of CPOP in patients undergoing video-assisted thoracic surgery.

Randomized Controlled TrialHigh thoracic epidural analgesia in cardiac surgery. Part 1--high thoracic epidural analgesia improves cardiac performance in cardiac surgery patients.
The purpose of this study was to evaluate the perioperative cardioprotective effect of high thoracic epidural analgesia (HTEA), primarily expressed as an effect on cardiac performance and hemodynamics in patients undergoing cardiac surgery. ⋯ The findings of a higher stroke volume index and central venous oxygenation without an increase in heart rate or mean arterial pressure suggest that HTEA improves cardiac performance in elderly cardiac surgery patients.

Raised jugular venous pressure intensifies release of brain injury biomarkers in patients undergoing cardiac surgery.
Neurologic damage after cardiac surgery with extracorporeal circulation is multifactorial. Despite several studies, its pathophysiology is poorly understood. The purpose of this study was to determine the changes in jugular venous pressure and to analyze their effect on perioperative brain injury measured by biomarkers in patients undergoing coronary artery bypass grafting. ⋯ Cardiac surgery increased JVBP and an increased JVBP > 12 mmHg intensified an increase in brain injury biomarker concentrations.
