Dabin Cheng, Lu Liu, Zheng Hu
OBJECTIVE: Propofol is a new anesthetic agent in clinical practice, but randomized double-blinded prospective studies on its role in pediatric anesthesia remain limited. We aimed to compare the preventive effects of pre-injected lidocaine or ketamine and its pre-mixture on the anesthesia-induced injection pain of propofol using a randomized double-blinded prospective method, and to compare the outcomes with those of medium-/long-chain propofol (M/LCT). METHODS: A total of 360 pediatric patients (aged 5-12 years old) who received elective surgery were randomly divided into six groups (n= 60) as follows...

BACKGROUND: This study examined variation between users of 'club' and 'hard' drugs in Taiwan in terms of prevalence of use and demographics and psychosocial characteristics. METHODS: Data were derived from a survey of 17,837 Taiwanese civilians, aged 12-64 years, using stratified, multi-stage, random sampling. Participants completed a computer-assisted self-interview on tablet computers which covered use of legal substances, sedatives/hypnotics and prescription analgesics; use of illicit drugs/inhalants, risky sexual experiences; expectations of drugs; and psychological distress...

BACKGROUND: Nonconvulsive status epilepticus (NCSE) is a diagnosis that is often challenging and one that may progress to refractory NCSE. Ketamine is a noncompetitive N-methyl-d-aspartate antagonist that increasingly has been used to treat refractory status epilepticus. Current Neurocritical Care Society guidelines recommend intravenous (IV) ketamine infusion as an alternative treatment for refractory status epilepticus in adults. On the other hand, enteral ketamine use in NCSE has been reported in only 6 cases (1 adult and 5 pediatric) in the literature to date...

This chapter summarizes recent developments in preclinical and clinical research on Chinese herbal medicines and their neurochemical mechanism of action for the treatment of drug addiction. We searched Chinese and English scientific literature and selected several kinds of Chinese herbal medicines that have beneficial effects on drug addiction. Ginseng (Renshen) may be clinically useful for the prevention of opioid abuse and dependence. Rhizoma Corydalis (Yanhusuo) may be used to prevent relapse to chronic drug dependence...

Introduction Select units in the military have improved combat medic training by integrating their functions into routine clinical care activities with measurable improvements in battlefield care. This level of integration is currently limited to special operations units. It is unknown if regular Army units and combat medics can emulate these successes. The goal of this project was to determine whether US Army combat medics can be integrated into routine emergency department (ED) clinical care, specifically medication administration...

BACKGROUND: Intraoperative hypothermia and postoperative pain control are two important clinical challenges in anesthesiology. Transient receptor potential vanilloid 1 has been implicated both in thermoregulation and pain. Transient receptor potential vanilloid 1 antagonists were not advanced as analgesics in humans in part due to a side effect of hyperthermia. This study tested the hypothesis that a single, preincision injection of a transient receptor potential vanilloid 1 antagonist could prevent anesthesia-induced hypothermia and decrease the opioid requirement for postsurgical hypersensitivity...

Sickle cell crises occur frequently during pregnancy and are difficult to treat, even with high-dose opioids. Analgesia with ketamine has been suggested as an alternative, but its use during pregnancy is underreported. Two pregnant patients with uncontrolled sickle cell pain were treated with ketamine. Patient A reported no decrease in her pain, but her opioid requirements decreased. Patient B's pain resolved during ketamine administration. No serious maternal or neonatal adverse effects occurred. Ketamine may be considered as an adjunct analgesic in pregnant patients with sickle cell pain, although prospective clinical data are needed to fully assess its efficacy...

The long-term effects of opioids on sensitization processes are believed to be mediated through the NDMA receptor. QST changes observed following a ketamine infusion have been previously described but the effect that chronic opioids will have is not known. The results of this prospective randomized factorial trial compared the thermal QST changes observed following a 0.05 mg/kg ketamine infusion or a saline placebo in chronic pain subjects who were either opioid-naïve or were chronically using opioids for chronic non-cancer pain are presented...

Short and long acting NMDA receptor (NMDAR) antagonists exert their antidepressant-like effects by activating signaling pathways involved in the synthesis of synaptic proteins and formation of new synaptic connections in the prefrontal cortex (PFC) of rats. The blockade of the ERK pathway abolishes ketamine and Ro 25-6981 antidepressant potency. However, the role of ERK in the antidepressant-like activity of short acting NMDAR antagonists is still unclear. More puzzling is the fact that the precise role of ERK role in the short and long lasting effects of long-acting NMDAR antagonists is unknown...

Ketamine and propofol are both commonly used emergency department (ED) procedural sedation agents. Their concurrent administration, often referred to as "ketofol", is widely used for procedural sedation. A simple google search can lead to a lot of opinions on why we should use propofol, ketamine, or ketofol in a given situation for moderate or deep procedural sedation in the ED, but finding evidence that supports differences these opinions assume is much harder to come by.

We reviewed the participation of the septohippocampal system in an animal model of schizophrenia that was acutely induced by systemic injection of an N-methyl-d-aspartate (NMDA) receptor antagonist such as phencyclidine, MK-801 and ketamine. The NMDA receptor antagonist-induced model of schizophrenia is characterized by behavioral and electrophysiological disruptions, including a decrease in prepulse inhibition of the acoustic startle response (PPI), hyperlocomotion, decrease in gating of hippocampal auditory evoked potentials and robust increase in hippocampal gamma (30-100Hz) oscillations...

Glutamatergic dysfunction is implicated in many neuropsychiatric conditions, including post-traumatic stress disorder (PTSD). Glutamate antagonists have shown some utility in treating PTSD symptoms, whereas glutamate agonists may facilitate cognitive behavioral therapy outcomes. We have developed an animal model of PTSD, based on conditioning of the rabbit's eyeblink response, that addresses two key features: conditioned responses (CRs) to cues associated with an aversive event and a form of conditioned hyperarousal referred to as conditioning-specific reflex modification (CRM)...

A brief burst-suppressing isoflurane anesthesia has been shown to rapidly alleviate symptoms of depression in a subset of patients, but the neurobiological basis of these observations remains obscure. We show that a single isoflurane anesthesia produces antidepressant-like behavioural effects in the learned helplessness paradigm and regulates molecular events implicated in the mechanism of action of rapid-acting antidepressant ketamine: activation of brain-derived neurotrophic factor (BDNF) receptor TrkB, facilitation of mammalian target of rapamycin (mTOR) signaling pathway and inhibition of glycogen synthase kinase 3β (GSK3β)...

OBJECTIVES: Obesity increases the risk of complications during pediatric procedural sedation. The risk of being underweight has not been evaluated in this arena. We therefore investigated the association of BMI with sedation dosing and adverse events in children across a range of BMIs. METHODS: A total of 1976 patients ages 2 to 21 years old with oncologic diagnoses underwent lumbar punctures and/or bone marrow aspirations. All children received a standard adjunctive dose of ketamine before sedation with propofol...

Chronic abuse of methylphenidate (MPH) often causes neuronal cell death. Topiramate (TPM) carries neuroprotective effects, but its exact mechanism of action remains unclear. In the present study, the role of various doses of TPM and its possible mechanisms, receptors and signaling pathways involved against MPH-induced hippocampal neurodegeneration were evaluated in vivo. Thus, domoic acid (DOM) was used as AMPA/kainate receptor agonist, bicuculline (BIC) as GABAA receptor antagonist, ketamine (KET) as NMDA receptor antagonist, yohimbine (YOH) as α2 adrenergic receptor antagonist and haloperidol (HAL) was used as dopamine D2 receptor antagonist...

BACKGROUND AND AIMS: Paediatric cardiac surgery with cardiopulmonary bypass (CPB) is associated with a marked inflammatory response and triggers release of inflammatory cytokines. The aim of this study was to study the effect of ketamine on the inflammatory response during correction of congenital cyanotic heart diseases. METHODS: Sixty-six patients with congenital cyanotic heart diseases scheduled for cardiac surgery were randomised into three groups. Group A patients did not receive ketamine (control group), Group B patients received 2 mg/kg ketamine intravenous (IV) and Group C patients received ketamine 2 mg/kg IV and an IV infusion of ketamine (50 μg/kg/min)...

Ketamine inhibits pentameric ligand-gated ion channels (pLGICs), including the bacterial pLGIC from Gloeobacter violaceus (GLIC). The crystal structure of GLIC shows R-ketamine bound to an extracellular intersubunit cavity. Here, we performed molecular dynamics simulations of GLIC in the absence and presence of R- or S-ketamine. No stable binding of S-ketamine in the original cavity was observed in the simulations, largely due to its unfavorable access to residue D154, which provides important electrostatic interactions to stabilize R-ketamine binding...
