BACKGROUND: Dexmedetomidine (DEX) has sedative, sympatholytic and analgesic effects and might be beneficial if used as an adjuvant to: improve analgesia; modulate haemodynamic responses to intubation and pneumoperitoneum and; reduce the number of opioid-associated adverse events. The aim of this study was to evaluate the efficacy and safety of DEX infusion during elective laparoscopic cholecystectomy (LC). METHODS: A randomized, single-centre, parallel-group, placebo-controlled study was carried out between May 2016 and June 2017...

OBJECTIVES: To determine whether implementing a guideline to bolus medications from continuous infusions in PICUs affects nursing satisfaction, patient safety, central line entries, medication utilization, or cost. DESIGN: This is a pre- and postimplementation quality improvement study. SETTING: An 11-bed ICU and 14-bed cardiac ICU in a university-affiliated children's hospital. PATIENTS: Patients less than 18 years old admitted to the PICU or pediatric cardiac ICU receiving a continuous infusion of dexmedetomidine, midazolam, fentanyl, morphine, vecuronium, or cisatracurium from May 2015 to May 2016, excluding November 2015 (washout period), were eligible for inclusion...

BACKGROUND: Dexmedetomidine (Dex) is an attractive agent for procedural sedation due to its unique pharmacodynamic profile, specifically affording predictable sedation without concurrent respiratory depression. However, Dex has previously been reported to prevent or terminate arrhythmias. The purpose of this study was to investigate paroxysmal supraventricular tachycardia (PSVT) inducibility and homeostatic stability during electrophysiology studies (EPSs) and ablation when a standardized Dex protocol was used as the primary sedation agent...

Background and Aims: Microlaryngeal surgery is a frequently performed ear, nose, and throat procedure used to diagnose and treat laryngeal disorders. Suspension laryngoscopy causes prolonged stimulation of the deep pressure receptors of the larynx leading to adverse circulatory responses and consequently cardiac complications. In this study, dexmedetomidine infusion was used to assess its effectiveness for attenuation of this hemodynamic stress response. Material and Methods: Sixty patients undergoing elective microlaryngeal surgery randomly received either dexmedetomidine 1 μg/kg over 10 min followed by continuous infusion of 0...

Background and Aims: The synergism between epidural local anesthetic agent and opioids is well established, but evidence for the combination of local anesthetic agent with dexmedetomidine in epidurals is limited. This study evaluates the clinical efficacy of dexmedetomidine versus fentanyl as an additive to ropivacaine for epidural anesthesia. Material and Methods: Patients undergoing infraumbilical surgeries were divided randomly into three groups - Group R (n = 25): received 18 ml of 0...

Background and Aims: Breast cancer surgery can be carried out as day-care procedure to increase patient turnover, decrease disease progression and financial burden. The present study was carried out to assess the role of dexmedetomidine in breast cancer surgery as a day-care procedure. Methods: This prospective randomised, double-blind study was carried out on 100 patients screened for day-care breast cancer surgery. They were divided into two groups of 50 each; who received either normal saline (Group NS) or 0...

Background: The goal of awake craniotomy is to maintain adequate sedation, analgesia, respiratory, and hemodynamic stability and also to provide a cooperative patient for neurologic testing. An observational study carried out to evaluate the efficacy of dexmedetomidine sedation for awake craniotomy. Materials and Methods: Adult patients with age >18 year who underwent awake craniotomy for intracranial tumor surgery were enrolled. Those who were uncooperative and had difficult airway were excluded from the study...

Background: Awake fiberoptic intubation (AFOI) is the gold standard for the management of predicted difficult airway, and inappropriate sedation is a major cause leading to its failure. Aims: The primary objective was to compare the heart rate (HR) changes that accompany AFOI following sedation with dexmedetomidine and fentanyl. Secondary objectives included comparison of changes in blood pressure, patient comfort, ease of intubation, and degree of sedation. Settings and Designs: This prospective double-blinded randomized study was conducted in a tertiary care institution...

BACKGROUND: In patients undergoing total knee arthroplasty under spinal anesthesia, we compared the postoperative analgesic effect of intraoperative sedation with dexmedetomidine versus propofol. We hypothesized that sedation with dexmedetomidine would result in lower postoperative opioid analgesic consumption than with propofol. METHODS: Forty-eight patients were enrolled and randomly assigned to either a dexmedetomidine group (n = 24), which received a loading dose of 1 μg/kg dexmedetomidine over 10 minutes, followed by a continuous infusion of 0...

REVIEW
Kyle J Kramer, Jason W Brady
Oral and maxillofacial surgeons have a variety of anesthetic agents that can be used to provide anesthesia safely and efficiently in the office-based environment. However, it is critical to have a thorough understanding of the particulars for each agent. Commonly used anesthetic agents, administered either individually or in combination, include diazepam, midazolam, propofol, ketamine, opioid agonists such as fentanyl or remifentanil, dexmedetomidine, and inhalational agents, including nitrous oxide and sevoflurane...

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)...

Patient sedation and analgesia on extracorporeal membrane oxygenation (ECMO) is vital for safety and comfort. However, adsorption to the circuit may alter drug pharmacokinetics and remains poorly characterized. This study characterizes drug adsorption of morphine, fentanyl, midazolam, and dexmedetomidine in an ex vivo infant ECMO circuit utilizing polymethylpentene (PMP) membrane oxygenator (MO) with protein-bounded polyvinylchloride (PVC) tubing. Twelve closed-loop ex vivo ECMO circuits were prepared using P...

Mario Arenillas, Ignacio A Gomez de Segura
Alfaxalone is a neuroactive steroid used as a general anaesthetic in several species including dogs, cats, rabbits and ferrets. It has a wide margin of safety and a similar anaesthetic profile to propofol. To increase its aqueous solubility, a new formulation with cyclodextrins has been marketed recently. The objective of this study was to evaluate the anaesthetic effect of several doses of alfaxalone alone, considering differences between sexes, and alfaxalone combined with dexmedetomidine and fentanyl in the rat administered by the intraperitoneal route...

BACKGROUND AND OBJECTIVES: Postoperatively, transplant recipients receive immunosuppressants, as well as sedatives and analgesics. The immunomodulatory effects of these other agents during the induction period following transplantation remain unclear. We aimed to determine whether the agents dexmedetomidine hydrochloride (Dex) and fentanyl (Fen) have immunomodulatory effects during the induction period following heart transplantation (HTx). METHODS: Fifty mice were used for antinociception tests after administration of Dex and Fen, and T cells from 3 naive animals were used for in vitro lymphocyte transformation test (study 1)...
