The original version of this Article contained an error in the third sentence of the 'Animal studies' section of the Methods, which incorrectly read 'The sheep anesthesia was initiated with ketamine (25 mg kg-1 ) and then maintained by continuous intravascular (IV) infusion of propofol (800 mg kg-1  h-1 ) during imaging.' The correct version states '800 µg kg-1  h-1 ' in place of '800 mg kg-1  h-1 '. This has been corrected in both the PDF and HTML versions of the article.

PURPOSE: Currently, there is a concern at the national level of the overuse of both prescription and nonprescription opioid use. The purpose of this study was to identify whether the use of the intravenous (IV) formulation of acetaminophen (Ofirmev; Mallinckrodt Pharmaceuticals, Staines-upon-Thames, United Kingdom) is an effective tool in the reduction of postoperative pain, with a secondary goal of reduction of postoperative narcotic use. MATERIALS AND METHODS: A total of 72 patients with previously diagnosed either partial bony or complete bony impacted third molars were selected with care to avoid long-acting local anesthetics or dissociative anesthetic agents...

Cortical release of the neurotransmitter dopamine has been implied in adapting cortical processing with respect to various functions including coding of stimulus salience, expectancy, error prediction, behavioral relevance, and learning. Dopamine agonists have been shown to modulate recurrent cortico-thalamic feedback, and should therefore also affect synchronization and amplitude of thalamo-cortical oscillations. In this study we have used multitaper spectral and time-frequency analysis of stimulus-evoked and spontaneous current source density patterns in primary auditory cortex of Mongolian gerbils to characterize dopaminergic neuromodulation of the oscillatory structure of current sources and sinks...

Increasing evidence indicate that pain is insufficiently treated following surgical procedures. It is essential that pain treatment is effective with a minimum of side effects in order to promote postoperative rehabilitation. Multimodal analgesia is most likely an important strategy in reducing postoperative pain. Combinations of different analgesics with different mechanisms of action may have an additive analgesic effect with fewer side effects compared to using a single drug. However, there is still a pronounced lack of documentation for the effect and side effects of these multimodal analgesic regimes...

BACKGROUND: Delirium is a neurobehavioural syndrome that frequently develops in the postoperative setting. The incidence of elderly patients who develop delirium during hospital stay ranges from 10 to 80% (Schonauer et al., J Pept Sci. 2017). Delirium was first described more than half a century ago in the cardiac surgery population (Blachy and Starr, Am J Psychiatry 121:371-5, 1964), where it was already discovered as a state that might be accompanied by serious complications such as prolonged ICU and hospital stay, reduced quality of life and increased mortality...

BACKGROUND: Pain management is important in pre-hospital care of patients with extremity trauma (ET). The goal of this study was to establish a rat model of ET for pre-hospital pain research, and validate it using pain behaviors and analgesics. METHODS: Rats were anesthetized using isoflurane and ET was induced in one hindlimb via clamping retrofemoral tissues for 30 sec, followed by closed fibula fracture. Rats regained consciousness after ET. Pain responses in the injured hindlimb to thermal hyperalgesia (paw withdrawal latency, PWL), mechanical allodynia (paw withdrawal pressure, PWP), and weight bearing (WB) were determined before and 90 minutes after ET...

BACKGROUND: Previous studies have evaluated prehospital analgesia during combat operations in Iraq and Afghanistan, but were limited to the adult population. However, a significant portion of the casualties of those conflicts were children. We describe the prehospital analgesia administered to wartime pediatric trauma patients. METHODS: We queried the Department of Defense Trauma Registry (DODTR) for all pediatric patients (<18 years of age) admitted to United States and Coalition fixed-facility hospitals in Iraq and Afghanistan from January 2007 to January 2016...

Objectives We evaluated the use of rocuronium 0.3 mg/kg intravenously (IV) to facilitate tracheal intubation in cats anesthetized for elective ovariohysterectomy. Methods Thirty female cats were randomly allocated to receive rocuronium 0.3 mg/kg IV or an equal volume of normal saline, following induction of anesthesia with ketamine and midazolam. Thirty seconds after induction, a single investigator, unaware of treatment allocation, attempted tracheal intubation. The number of attempts and the time to complete intubation were measured...

BACKGROUND: Acetate-containing colloid infusion solutions are recommended to recover normovolemia during pediatric anesthesia. Until now, no studies investigating the compatibility with common anesthetic drugs were available. AIMS: This in vitro study was conducted to reveal possible incompatibilities between common anesthetic drugs and the acetate-containing colloid infusion solutions 6% hydroxyethyl starch and 4% gelatin with normal saline as control. METHODS: The colloid infusion solutions were mixed 1:1 with 29 common intravenous drugs in concentrations used in daily clinical practice...

Four captive reindeer underwent anaesthesia to allow dehorning or drainage of lymph nodes abscessation. Premedication was based on xylazine (dose range: 0.075- 0.5 mg/kg, IM or IV), with or without ketamine (dose range: 1-2 mg/kg, IM or IV), all of which failed to produce effective sedation without side effects. During anaesthesia, 2 reindeer experienced severe hypoxaemia and hypoventilation. Recovery was smooth in 3 out 4 animals, but delayed in one reindeer sedated with 0.5 mg/kg of xylazine IV; this patient required repeated atipamezole administrations (0...

RATIONALE: Depressive episodes are the leading cause of mental health-related hospital admissions in Australia, and 44% of those admitted have a previous history of hospitalisations for depression (Admitted patient mental health-related care: (Australian Institute of Health and Welfare Aust Hospital Stat 2011-12, 2013). Despite numerous available antidepressant treatments, many patients do not respond to conventional therapy, having what is called 'treatment resistance' (Fava Biol Psychiatry 53:649-659, 2003)...

Volatile agents are widely used to anaesthetise laboratory non-human primates as they allow a rapid induction and recovery as well as an easy adjustment of the anaesthesia plan. Desflurane is currently the volatile agent with the lowest solubility in blood, and hence enables the most rapid onset of anaesthesia and most rapid recovery. This study aimed to investigate the suitability of desflurane for maintenance of general anaesthesia in rhesus macaques undergoing elective experimental neurosurgery. Fourteen primates (five males and nine females) were sedated with ketamine (10 mg kg(-1)) and anaesthesia was induced with propofol (usually 8 mg kg(-1) IV)...

Mast cell (MC) degranulation has been implicated in the side effect profile of a variety of clinically useful agents. Thus, after intrathecal delivery, formation of space-occupying, meningeally-derived masses may be related to local MC degranulation. We systematically characterized degranulating effects of opioid and nonopioid analgesics on cutaneous flares in the dog and in primary human MC (hMC) cultures. METHODS: Dogs were anesthetized with IV propofol and received intradermal (ID) injections (50μL)...

Non-NMDA receptor-mediated vibrotactile responses of neurons from the hindpaw representation were investigated in the rat SI cortex. We recorded single-unit spikes evoked by sinusoidal (duration: 500 ms; frequency: 5, 40, and 250 Hz; amplitude: 100 μm peak-to-peak) stimulation of the glabrous skin. The responses were obtained with microinjection of aCSF (sham), bicuculline, and AMPA near the isolated neurons in anaesthetized rats. Blocking most of the NMDA receptors by ketamine revealed local dynamics differentially modulated by each drug...

BACKGROUND: In order to determine whether a combination of guaiphenesin, ketamine and xylazine can induce safe and satisfactory anaesthesia in mules undergoing field castration, eight healthy adult intact male mules were employed. They were premedicated with intravenous (IV) xylazine (1.3 mg/kg); an additional dose of xylazine (0.3 mg/kg IV) was administered in case of inadequate depth of sedation. Anaesthesia was induced with IV thiopental (6 mg/kg). The quality of sedation and induction was recorded...
