BACKGROUND Transient global cerebral ischemia/reperfusion (I/R) is a major perioperative complication, and diabetes increases the response of oxidative stress and inflammation induced by I/R. The objective of this study was to determine the protective effect of dexmedetomidine against transient global cerebral ischemia/reperfusion induced oxidative stress(More)
Transversus abdominis plane (TAP) block is an analgesic technique. Adding dexmedetomidine can enhance regional anesthesia. This study’s aim was to evaluate whether dexmedetomidine prolonged analgesic time of TAP block after gastrectomy. Patients scheduled for gastrectomy were randomly assigned to receive a TAP block with saline (group S), ropivacaine (group(More)
Neurogenic pulmonary edema (NPE) is an acute and serious complication after a central nervous system insult with high mortality. The pronounced activation of sympathetic nervous system and the release of vasoactive substances are necessary prerequisites for the development of NPE. We introduce a hypothesis that stellate ganglion block (SGB) may prevent NPE(More)
The aim of this study was to assess the systemic and analgesic effects of epidural dexmedetomidine in thoracic epidural anaesthesia (TEA) combined with total intravenous anaesthesia during thoracic surgery. Seventy-one patients undergoing open thoracotomy were included in this study and randomly divided into three groups: Control group (Group C): patients(More)
