dexmedetomidine ovar*

James Mack Fudge, Bernie Page, Amy Mackrell, Inhyung Lee
OBJECTIVES: This study sought to determine if bupivacaine targeted at specific, potentially painful sites could enhance postoperative analgesia in routine feline ovariohysterectomies. A secondary objective was to assess the utility of multiple acute pain scales for cats in a high-volume surgery setting. METHODS: Two hundred and twelve cats were included in a prospective, randomized, double-blinded, placebo-controlled clinical trial. Anesthesia included buprenorphine, ketamine, dexmedetomidine and isoflurane...

Objective: To observe the effects of dexmedetomidine on cerebral oxygen saturation and postoperative recovery in elderly patients with ovarian cancer. Methods: Sixty elderly patients with ovarian cancer were randomly divided into two groups. Both groups were given total intravenous anesthesia. Patients in group D were given a loading dosage of dexmedetomidine 0.5 μg/kg, followed by continuous infusion 0.2 μg·kg(-1)·h(-1) until 30 minutes before the end of operation. Group C were given normal saline at the same time...

The aim of this study was to determine the efficacy and pharmacokinetics of bupivacaine in combination with epinephrine or dexmedetomidine after intraperitoneal administration in cats undergoing ovariohysterectomy. Sixteen healthy adult cats (3.3 ± 0.6 kg) were included in a prospective, randomized, masked clinical trial after obtaining owners' consent. Anesthetic protocol included buprenorphine-propofol-isoflurane. Meloxicam [0.2 mg/kg body weight (BW)] was administered subcutaneously before surgery. Cats were randomly divided into 2 groups to receive 1 of 2 treatments...

The aim of this study was to evaluate the effects of a low dose dexmedetomidine constant rate infusion (CRI) on cardiopulmonary function, inhalant anesthetic concentration and recovery in isoflurane anesthetized cats. In a prospective, randomized, blinded, controlled design, 12 cats undergoing anesthesia for ovariohysterectomy were administered hydromorphone (0.1mg/kg) intramuscularly, propofol (4.3-7.8mg/kg) intravenously and maintained with isoflurane. During isoflurane anesthesia, the cats were administered either a dexmedetomidine loading dose (0...

This study compared the efficacy of intravenous (IV) fentanyl and ketamine with lumbosacral epidural lidocaine in dogs undergoing ovariohysterectomy. Dogs with esophageal Doppler monitoring ( n = 112) were included in this retrospective study. All dogs were premedicated with dexmedetomidine and methadone, induced with IV propofol or alfaxalone and maintained using isoflurane and IV fentanyl, IV ketamine, or epidural lidocaine. Heart rate (HR), mean arterial pressure (MAP), expired fraction of isoflurane (ETIso), stroke distance (SD), minute distance (MD), peak velocity (PV) and mean acceleration (MA) were recorded before and after ligation of the ovarian pedicle (OvP)...

OBJECTIVES: During this study, we aimed to analyze the correlation between dosages of dexmedetomidine (DEX) and the p38MAPK/NF-κB signaling pathway, and their effects on immune function and tumor growth in rats with ovarian cancer (OC). METHODS: A total of 100 rats were selected for the purposes of the study. The normal group consisted of 20 rats, while the remaining 80 rats were utilized for OC model establishment purposes, and further assigned into the model, 0...

Objectives This was a randomised, blinded trial to investigate the influence of administration rate on the dose of propofol required for the orotracheal intubation of cats. Methods Twenty-four female domestic cats undergoing ovariohysterectomy were premedicated with oral tramadol (6 mg/kg) or intramuscular tramadol (4 mg/kg), and intramuscular dexmedetomidine (0.007 mg/kg). Oral or intramuscular (IM) tramadol was administered 60 or 30 mins prior to induction of anaesthesia, respectively. Dexmedetomidine was administered 30 mins prior to anaesthetic induction...

BACKGROUND: Anti-N-methyl-d-aspartate receptor (NMDA-R) encephalitis is a recently identified but increasingly recognized autoimmune paraneoplastic disease. Because these patients present complex neuropsychiatric symptoms due to NMDA-R dysfunction, the optimal methods of sedation/anesthesia remain controversial. Here, we present animal experiment data, along with a related case report, implying the safe and effective use of dexmedetomidine in patients with anti-NMDA-R encephalitis. FINDINGS: (1) Animal experiment: in order to investigate whether dexmedetomidine may interfere with NMDA-R activity, an NMDA antagonist (MK-801) model in rats was used to simulate anti-NMDA-R encephalitis...

Anaesthetic and analgesic effects of three different injectable anaesthetic combinations for prepubertal gonadectomy (PPG) in cats were studied. One anaesthetic protocol was compared with a similar one for gonadectomy at traditional age (TAG). Kittens were randomly assigned to PPG or TAG. For PPG, three different protocols were compared: (1) intramuscular (IM) administration of 60 μg/kg dexmedetomidine plus 20 μg/kg buprenorphine followed by an IM injection of the anaesthetic agent (20 mg/kg ketamine) (DB-IM protocol); (2) oral transmucosal (OTM) administration of 80 μg/kg dexmedetomidine plus 20 μg/kg buprenorphine followed by an IM injection of 20 mg/kg ketamine combined with 20 µg/kg dexmedetomidine (DB-OTM protocol); (3) IM injection of a 40 μg/kg medetomidine-20 μg/kg buprenorphine-20 mg/kg ketamine combination (MBK-IM protocol)...

Reperfusion has always been "the emergency intervention" to ischemic tissue. For a given period of time, tissue injury due to ischemia and reperfusion is more serious than injury due to ischemia only. Groups were as: Group 1: 25 µg/kg dexmedetomidine + ischemia/reperfusion group. Group 2: 10 mg/kg yohimbine +25 µg/kg dexmedetomidine + ischemia/reperfusion group. Group 3: Ischemia/reperfusion (control) group. Group 4: Healthy rats. Rat ovaries were exposed to a 3-hour ischemia and then reperfusion ensured for 2 hours...
