Comparison of the Effects of Dexmedetomidine and Labetalol on Controlled Hypotension in Maxillofacial Surgery
Background & objectives: The use of controlled hypotension is important to reduce bleeding in some surgeries. This study aimed to determine the effects of dexmedetomidine (DEX) and labetalol for induced hypotension in maxillofacial fractures surgery. Methods: In this triple-blind randomized controlled clinical trial study, the patients with maxillofacial fractures were randomly divided into two...
متن کاملHaemodynamic effects of labetalol-induced hypotension in the anaesthetized dog.
Central haemodynamic changes and regional blood flow were studied using the microsphere technique, during labetalol-induced hypotension in dogs anaesthetized with pentobarbitone and fentanyl. Labetalol 15 mg kg-1 decreased mean arterial pressure from an average of 88 mm Hg to 47 mm Hg. Mean pulmonary arterial pressure was unchanged. Cardiac output was reduced by decrease in stroke volume, while...
متن کاملEnflurane for controlled hypotension.
Enflurane was substituted for halothane in an established technique of controlled hypotension, involving beta-blockade and sympathetic ganglion blockade, for 2 groups of patients. One group was undergoing major plastic surgery and/or major maxillo-facial surgery and these patients breathed spontaneously. The other group was undergoing major neurosurgery and received intermittent positive pressu...
متن کاملLabetalol infusion for refractory hypertension causing severe hypotension and bradycardia: an issue of patient safety
Incremental doses of intravenous labetalol are safe and effective and, at times, such therapy may need to be augmented by a continuous infusion of labetalol to control severe hypertension. Continuous infusions of labetalol may exceed the recommended maximum daily dose of 300 mg on occasion. We report a case in which hypertension occurring after an abdominal aortic aneurysm repair, initially res...
متن کاملOrgan perfusion during controlled hypotension.
Relatively short periods of unwanted hypotension, such as those associated with "shock" states, may be followed by irreversible organ damage. In contrast, controlled hypotension is rarely followed by organ damage, although minor reversible changes in function may occur (Rollason and Hough, 1960; Enderby, 1961; Linacre, 1961). The usual explanation for this paradox is that in the former situatio...
