Randomized Controlled Trial Comparative Study
Effects of epidural anesthesia on acute and chronic pain after coronary artery bypass grafting.
To evaluate the effects of thoracic epidural anesthesia (TEA) as an adjunct to general anesthesia (GA) on postoperative pain after coronary artery bypass grafting (CABG). ⋯ TEA significantly reduced the intensity of postoperative pain and analgesic consumption in the early postoperative period following CABG. The delivery of effective analgesia along with conventional medications may prevent chronic pain after surgery.

Concerns of increased surgical risks with ascending aortic replacement have led surgeons to manage post-stenotic aortic dilatation more conservatively during aortic valve replacement (AVR). The present study aimed to assess the prognostic implications and surgical risks of replacing the dilated aorta during AVR. ⋯ Concomitant replacement of the dilated ascending aorta during AVR did not increase the immediate postoperative morbidity or mortality risks and tended to exert a long-term beneficial effect on the risk of late mortality.

Near-infrared spectroscopy (NIRS) is a noninvasive continuous monitoring method for measuring the oxyhemoglobin saturation of the brain tissue. NIRS monitoring can suggest neuronal hypoxia in the frontal-brain before irreversible impairment of cellular metabolism. We report two cases of Type B aortic dissection surgery in which spinal regional perfusion monitoring was performed by placing two NIRS sensors on the back-skin through T6-T8 and T9-T11 vertebraes.
