C Elalouf, A-G Le Moing, C Fontaine, A Leke, G Kongolo, J Gondry, P Tourneux
OBJECTIVE: Although ketamine analgesia is effective in reducing pain and facilitating the tracheal intubation of newborns in the delivery room, no data on the neurological effects of this treatment are available. This study compared the neurodevelopmental outcomes at 2 years of age in a cohort of preterm newborns having received ketamine prior to tracheal intubation at birth (the ketamine group) and in a control group. METHODS: We included newborns delivered at less than 33 weeks gestational age (WGA) having undergone tracheal intubation at birth...

PURPOSE OF REVIEW: Complex regional pain syndrome (CRPS) is a painful debilitating neurological condition that accounts for approximately 1.2% of adult chronic pain population. Ketamine, an NMDA receptor antagonist, is an anesthetic agent that has been used by some pain specialists for CRPS. There is a growing body of clinical evidence to support the use of ketamine in the treatment of neuropathic pain, especially CRPS. This meta-analysis study was aimed to examine the efficacy of ketamine in the treatment of CRPS...

Although beneficial in acute and chronic pain management, the use of local anaesthetics is limited by its duration of action and the dose dependent adverse effects on the cardiac and central nervous system. Adjuvants or additives are often used with local anaesthetics for its synergistic effect by prolonging the duration of sensory-motor block and limiting the cumulative dose requirement of local anaesthetics. The armamentarium of local anesthetic adjuvants have evolved over time from classical opioids to a wide array of drugs spanning several groups and varying mechanisms of action...

Fluoroquinolones are widely prescribed antibiotics, used for various infectious etiologies. These antibiotics carry the possibility of the serious adverse effect of peripheral neuropathy, with a true incidence not known owing to its rare existence. Recently, the Food and Drug Administration (FDA) has required alterations to drug labels to highlight this adverse effect of fluoroquinolones. This is a case report of a single patient at an inpatient neurology service at an urban academic medical center in the United States...

Neurologic deterioration following acute injury to the central nervous system may be amenable to pharmacologic intervention, although, to date, no such therapy exists. Ketamine is an anesthetic and analgesic emerging as a novel therapy for a number of clinical entities in recent years, including refractory pain, depression, and drug-induced hyperalgesia due to newly discovered mechanisms of action and new application of its known pharmacodynamics. In this focused review, the evidence for ketamine as a neuroprotective agent in stroke, neurotrauma, subarachnoid hemorrhage, and status epilepticus is highlighted, with a focus on its applications for excitotoxicity, neuroinflammation, and neuronal hyperexcitability...

OBJECTIVES: Currently ketamine is not used often as an analgesic in the emergency department (ED). Nonetheless, it can increase the efficiency of opioids and decrease their side effects. The purpose of this systematic review and meta-analysis was to evaluate whether low-dose ketamine in the ED provides better analgesia with fewer adverse effects. METHODS: The PubMed, EMBASE, and Cochrane Library databases were searched by two reviewers independently (last search performed on January 2016)...

Craniotomy pain may be severe and is often undertreated. Pain management following craniotomy is a balancing act of achieving adequate analgesia but avoiding sedation, respiratory depression, hypercapnia, nausea and vomiting, and hypertension. Opioids are a first-line analgesic therapy; however, concern that opioid-related adverse effects (sedation, respiratory depression) may interfere with neurologic assessment and increase intracranial pressure has limited use of these drugs for intracranial surgery. Non-opioid analgesics avoid these effects and may be useful as part of a multimodal regimen for post-craniotomy pain...

Daily interruption of sedative therapy and limitation of deep sedation have been shown in several randomized trials to reduce the duration of mechanical ventilation and hospital length of stay, and to improve the outcome of critically ill patients. However, patients with severe acute brain injury (ABI; including subjects with coma after traumatic brain injury, ischaemic/haemorrhagic stroke, cardiac arrest, status epilepticus) were excluded from these studies. Therefore, whether the new paradigm of minimal sedation can be translated to the neuro-ICU (NICU) is unclear...

BACKGROUND AND AIMS: Spinal anesthesia for cesarean section (CS) is associated with an incidence of hypotension of 60-94%. This study hypothesizes that intrathecal combination of low-dose ketamine, midazolam, and low-dose bupivacaine improves hemodynamics and postoperative analgesia compared with fentanyl and low-dose bupivacaine during CS. MATERIAL AND METHODS: Fifty parturients undergoing elective CS were randomized equally to receive ketamine (10 mg), midazolam (2 mg) and 0...

PURPOSE OF REVIEW: Deep brain stimulation (DBS) is a well tolerated and efficacious surgical treatment for movement disorders, chronic pain, psychiatric disorder, and a growing number of neurological disorders. Given that the brain targets are deep and small, accurate electrode placement is commonly accomplished by utilizing frame-based systems. DBS electrode placement is confirmed by microlectrode recordings and macrostimulation to optimize and verify target placement. With a reliance on electrophysiology, proper anaesthetic management is paramount to balance patient comfort without interfering with neurophysiology...

One of the most fascinating drugs in the anesthesiologist's armament is ketamine, an N-methyl-D-aspartate receptor antagonist with a myriad of uses. The drug is a dissociative anesthetic and has been used more often as an analgesic in numerous hospital units, outpatient pain clinics, and in the prehospital realm. It has been used to treat postoperative pain, chronic pain, complex regional pain syndrome, phantom limb pain, and other neuropathic conditions requiring analgesia. Research has also demonstrated its efficacy as an adjunct in psychotherapy, as a treatment for both depression and posttraumatic stress disorder, as a procedural sedative, and as a treatment for respiratory and neurologic conditions...

INTRODUCTION: Postoperative delirium is one of the most common complications of major surgery, affecting 10-70% of surgical patients 60 years and older. Delirium is an acute change in cognition that manifests as poor attention and illogical thinking and is associated with longer intensive care unit (ICU) and hospital stay, long-lasting cognitive deterioration and increased mortality. Ketamine has been used as an anaesthetic drug for over 50 years and has an established safety record. Recent research suggests that, in addition to preventing acute postoperative pain, a subanaesthetic dose of intraoperative ketamine could decrease the incidence of postoperative delirium as well as other neurological and psychiatric outcomes...

BACKGROUND: There is an emerging association between ketamine abuse and the development of urological symptoms including dysuria, frequency and urgency, which have a neurological component. In addition, extreme cases are associated with severe unresolving bladder pain in conjunction with a thickened, contracted bladder and an ulcerated/absent urothelium. Here we report on unusual neuropathological features seen by immunohistology in ketamine cystitis. RESULTS: In all cases, the lamina propria was replete with fine neurofilament protein (NFP+) nerve fibres and in most patients (20/21), there was prominent peripheral nerve fascicle hyperplasia that showed particular resemblance to Morton's neuroma...

Neuropathic pain (NP) is a debilitating condition associated with traumatic, metabolic, autoimmune and neurological etiologies. Although the triggers for NP are diverse, there are common underlying pathways, including activation of immune cells in the spinal cord and up-regulation of the N-methyl-D-aspartate receptor (NMDAR). Ketamine, a well-known NDMAR antagonist, reduces neuropathic pain in a sustained manner. Recent study has shown that the novel 11-amino acid peptide erythropoietin derivative ARA290 produces a similar, long-lasting relief of NP...

Ketamine has been the commonest abusive substance used by Hong Kong teenager since 2005. It is also the fourth commonest poison encountered in Hong Kong Poison Information Centre (HKPIC) poisoning data in 2010. From June 2008 to July 2011, HKPIC managed 188 and 96 cases of acute and chronic ketamine poisoning, respectively, which reflect its acute and chronic toxicity pattern. Demographically, there is a male predominance, and the majority is between the ages of 10-39. For the acute cases, 48 % presented with neurological features such as confusion, drowsiness, or transient loss of consciousness which usually subside with supportive care in a few hours...

Chemotherapy-induced peripheral neuropathy (CIPN) is a common, dose-limiting side effect of many chemotherapeutic agents. Although many therapies have been investigated for the prevention and/or treatment of CIPN, there is no well-accepted proven therapy. In addition, there is no universally accepted, well-validated measure for the assessment of CIPN. The agents for which there are the strongest preliminary data regarding their potential efficacy in preventing CIPN are intravenous calcium and magnesium (Ca/Mg) infusions and glutathione...

Ketamine is an N-methyl-D-aspartate receptor antagonist that has been in clinical use in the USA for over 30 years. Its ability to provide profound analgesia and amnesia while maintaining spontaneous respiration makes it an ideal medication for procedure-related pain and trauma. In the chronic pain arena, its use continues to evolve. There is strong evidence to support its short-term use for neuropathic and nociceptive pain, and conflicting evidence for preemptive analgesia. Its potential ability to prevent 'windup' and, possibly, 'reboot' aberrant neurologic pathways in neuropathic and central pain states has generated intense interest...
