Hao Cheng, Zhongmin Li, Nilas Young, Douglas Boyd, Zane Atkins, Fuhai Ji, Hong Liu
OBJECTIVE: The goal of this retrospective study was to investigate the effects of perioperative use of dexmedetomidine (Dex) on outcomes for older patients undergoing cardiac surgery. DESIGN: Retrospective investigation. SETTING: Patients from a single tertiary medical center. PARTICIPANTS: A total of 505 patients (≥65 years old) who underwent coronary artery bypass graft (CABG) or valve surgery. CABG and/or valve surgery plus other procedures were divided into 2 groups: 283 received intravenous Dex infusion (Dex group) and 222 did not (Non-Dex group)...

OBJECTIVE: To determine a dose of MK-467, a peripheral α2 -adrenoceptor antagonist, which, when administered intravenously (IV) concomitantly with 25 μg kg(-1) of dexmedetomidine, will prevent bradycardia without altering sedation in cats. STUDY DESIGN: Prospective, randomized, controlled, blinded, experimental, crossover study. ANIMALS: Eight healthy, adult, purpose-bred cats. METHODS: Cats were administered seven IV treatments were administered at least 2 weeks apart, consisting of dexmedetomidine 12...

PURPOSE: Oxidative renal injury is the mainstay in patients with spinal cord injury (SCI) and it may eventuate to chronic renal failure. In our study, we investigated the potential of α2-adrenoreceptor agonist Dexmedetomidine (Dex) in ameliorating SCI provoked oxidative renal assault. METHODS: Complete SCI was generated by surgical transaction of the cord at the T10-12 level. Dex administration (50 mcg/kg, b.wt, intraperitoneally) was initiated 12 h after the surgery for 10 days...

OBJECTIVES: Acute kidney failure after coronary artery bypass grafting (CABG) is a serious complication that increases morbidity and mortality rates. Early detection and prevention of this complication are very important. A novel biomarker named neutrophil gelatinase-associated lipocalin (NGAL) can play an important role in early diagnosis of acute kidney injury. Recent studies on the favourable effects of Dexmedetomidine on cardiac surgery have been published. The aim of this study is to investigate whether there is a dose-dependent positive effect of Dexmedetomidine on neutrophil gelatinase-associated lipocalin levels and renal functions when used after CABG...

OBJECTIVES: Ischemia/reperfusion (I/R) injury in the kidney during perioperative period remains the leading cause of acute renal failure. The purpose of this experimental study was to determine the role of dexmedetomidine (Dex) on renal I/R injury in rats. MATERIALS AND METHODS: Male Wistar rats, subjected to renal ischemia for 45 min, were either untreated or treated with dexmedetomidine 30 min prior to renal ischemia. A sham-operated group served as the control...

BACKGROUND AND OBJECTIVES: We investigated the effect of dexmedetomidine on ischemic renal failure in rats. METHODS: In the present study, 26 male adult Wistar albino rats weighting 230-300 g were randomly separated into four groups: sham-operated (n=5), ischemia reperfusion (IR) (IR group, n=7), IR/reperfusion treatment with dexmedetomidine (Dex. R group, n=7) and IR/pre-ischemic treatment with dexmedetomidine (Dex. I group, n=7). In the first group, sham operation was achieved and renal clamps were not applied...

INTRODUCTION: Optimal management of sedation, analgesia and delirium offers comfort and security for the critical care patient, allows support measures to be applied more easily and enables an integral approach of medical care, at the same time that lowers the incidence of complications, wich translates in better patient outcomes. OBJECTIVE: To update the Guía de práctica clínica basada en la evidencia para el manejo de la sedoanalgesia en el paciente adulto críticamente enfermo published in Medicina Intensiva in 2007, and give recommendations for the management of sedation, analgesia, and delirium...

BACKGROUND: Cardiac surgery is associated with a high risk of cardiovascular and other complications that translate into increased mortality and healthcare costs. This retrospective study was designed to determine whether the perioperative use of dexmedetomidine could reduce the incidence of complications and mortality after cardiac surgery. METHODS AND RESULTS: A total of 1134 patients who underwent coronary artery bypass surgery and coronary artery bypass surgery plus valvular or other procedures were included...

An 85 year old man with a history of chronic renal insufficiency was admitted to the cardiothoracic intensive care unit after aortic valve replacement. His postoperative course was marked by acute oliguric renal failure for high blood urea nitrogen (BUN) and acute hyperactive delirium. At this time he also developed tremors with muscle twitching; he received no other form of sedatives. A neurology consult made the diagnosis of twitch-convulsive syndrome associated with uremic encephalopathy. While the patient was receiving the dexmedetomidine infusion, the signs of the twitch-convulsive syndrome, particularly the twitching and tremors, disappeared...

We safely administered dexmedetomidine (DEX) for sedation during spinal anesthesia in a very elderly patient. The patient was a 98-year-old woman who had hypertension, renal failure, and first-grade atrioventricular block. She was scheduled to undergo internal fixation for fracture of the femoral neck. Initially, DEX (6.0 μg/kg/h) was administered over 10 min, followed by continuous infusion at a dose of 0.7 μg/kg/h. Consequently, her Ramsay sedation score (RSS) increased to 5, and the patient did not grimace in pain while being turned to the lateral position...

BACKGROUND AND OBJECTIVE: The study investigated the effect of intravenous dexmedetomidine on brachial plexus block in patients with end-stage renal disease sedated with dexmedetomidine or midazolam for the formation of arteriovenous fistula. METHODS: A supraclavicular brachial plexus block was performed in 68 patients scheduled for an arteriovenous fistula formation. A successful block was achieved in 64 patients (94%). Sixty-four patients received either dexmedetomidine (loading dose 1 microg kg 10 min followed by infusion of 0...

BACKGROUND AND OBJECTIVES: Perioperative acute renal failure increases morbidity and mortality. Alpha2-adrenergic agonists used in anesthesia increase urinary output and maintain cardiovascular stability. This study aimed at investigating the effects of dexmedetomidine on renal system and on vasopressin plasma levels in anesthetized dogs. METHODS: This study involved 36 adult mixed-breed dogs anesthetized with propofol, fentanyl, and isoflurane, which were randomly distributed in three groups receiving: G1 -20 mL of 0...

Ischemia-reperfusion (I-R) injury remains the leading cause of acute renal failure. The purpose of this experimental study was to determine the role of dexmedetomidine on histologic alterations induced by renal I-R in rats. In the present study, thirty male Sprague-Dawley rats weighing 200-220 g were randomly assigned into three groups: the sham-control group (group 1, n = 10), the R/untreated group (group 2, n = 10), and the I-R/dexmedetomidine-treated group (group 3, n = 10). For group one, we performed a sham operation...

PURPOSE: About 50 % of indications for dialysis in acute renal failure are related to problems originated during the perioperative period. Intraoperative hemodynamic changes lead to renal vasoconstriction and hypoperfusion. Previous studies have not defined the dexmedetomidine renal role in hemorrhage situations. This study evaluated the effect of dexmedetomidine on renal function and histology after acute hemorrhage in rats. METHODS: Covered study with 20 Wistars rats, anesthetized with sodium pentobarbital, 50 mg...
