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...
Introduction. Intradialytic hypotension (IDH) is a common complication during hemodialysis which may increase mortality risks. Low dose of Korean red ginseng (KRG) has been reported to increase blood pressure. Whether KRG can improve hemodynamic stability during hemodialysis has not been examined. Methods. The 8-week study consisted of two phases: observation phase and active treatment phase. A...
We have examined the safety of induced hypotension produced by extradural anaesthesia in patients with medically controlled hypertension. The haemodynamic response to induced hypotension was assessed in 38 non-hypertensive and 31 controlled hypertensive patients. All received extradural anaesthesia to T4 or above which decreased mean arterial pressure to 52 mm Hg and 55 mm Hg in normotensive an...
hypotension occurs during spinal anesthesia. Only one prior case has been published describing profound hypotension in a parturient with bipolar disease, controlled with lithium and risperidone, undergoing spinal anesthesia for Cesarean delivery. The patient was refractory to conventional treatment with ephedrine and iv fluids, and eventually responded to large doses of phenylephrine.2 The trea...
1. A progressive but incomplete adaptation of the aortic baroreceptor was observed after 1 and 6 h of hypotension in rats subjected to controlled bleeding. Administration of phenoxybenzamine produced a greater downward displacement of baroreceptor activation range. 2. Complete adaptation was observed after 48 h of maintained hypotension in rats treated with reserpine. 3. The range of the aortic...
Background: Blood loss is one of the most critical problems in major surgery. Spinal surgery usually associated with considerable blood loss and allogenic transfusions. Controlled hypotension is one of efficient methods for decreasing operative blood loss. The objective of this study was evaluation of the efficacy of magnesium sulfate in comparison with remifentanil for induction of relative hy...
Introduction: Abdominal aortic aneurysm is a multifactorial condition which associated with aging and atherosclerosis. During aneurysm surgery, hypotension after aortic clamp removing occure commonly that require specific treatments. This case report showes administration of blood and hemodynamic control methods after aortic unclumping during aortic aneurysm surgery. Patient: A 75–years-o...
