Levobupivacaine versus Levobupivacaine Plus Dexmedetomidine in Transversus Abdominis Plane Block in Patients Undergoing Abdominal Aortic Surgery.

Background: Severe postoperative pain is a major dilemma for patients undergoing abdominal aortic surgery. Transversus abdominis plane (TAP) block has been described a successful pain management technique after major abdominal surgery. Dexmedetomidine was proved to enhance the analgesic action of local anesthetics.

Efficacy of Dexmedetomidine versus Propofol in Patients Undergoing Endoscopic Transnasal Transsphenoidal Pituitary Tumor Resection.

Background: Dexmedetomidine is associated with good perioperative hemodynamics together with decreased opioid requirements. Furthermore, propofol has been used to achieve hypotensive anesthesia as a part of total intravenous anesthesia.

Aims: This study was performed to compare dexmedetomidine and propofol on the adequacy of hypotensive anesthesia during transsphenoidal resection of pituitary tumors.
