BACKGROUND: Rates of completed suicide in the military have increased. Options are limited for acute relief of depression and suicidal ideation. Traditional treatments' effects take weeks to months. A novel, rapid, therapeutic target has emerged with the N-methyl-D-aspartate antagonist ketamine. Previous studies suggest that a single dose of intravenous (IV) ketamine rapidly alleviates depression and suicidality. METHODS: In this proof of concept study, an active duty convenience sample population presenting to the emergency department (ED) meeting criteria for inpatient psychiatric admission as a result of depression and suicidal thinking were randomized to receive either a subdissociative dose (0...

BACKGROUND: Children undergoing computerized tomography (CT) frequently require sedation to allay their anxiety, and prevent motion artifacts and stress of intravenous (IV) cannulation. AIMS: The aim of this trial was to compare the effectiveness of oral midazolam and intranasal dexmedetomidine as sole premedicants in children for carrying out both IV cannulation as well as CT scanning, without the need for additional IV sedatives. METHODS: Fifty-nine children, aged 1-6 years, scheduled to undergo CT imaging under sedation were randomized to receive either 0...

Pain and sedation management for patients undergoing burn dressing change can be challenging. Variations appear to exist in the selection of medications before and during burn dressing change. To determine if institutional variations exist in pain and sedation management for burn dressing change, an online survey was sent to ABA Burn Center nurses and physicians. Three hundred seventy-eight anonymous responses were received from nurses (72%), nurse practitioners (10%), and physicians (18%). Burn centers had adult (22%), pediatric (12%), or pediatric and adult (66%) patients...

BACKGROUND: Ketogenic diet (KD) has been used to treat refractory status epilepticus (RSE). KD is a high-fat, restricted-carbohydrate regimen that may be administered with different fat to protein and carbohydrate ratios (3:1 and 4:1 fat to protein and carbohydrate ratios). Other ketogenic regimens have a lower fat and higher protein and carbohydrate ratio to improve taste and thus compliance to treatment. We describe a case of RSE treated with intravenous KD in the Pediatric Intensive Care Unit (PICU)...

A SPE-LC-MS/MS method for the determination of ketamine (KET) and norketamine (NKET) was developed and validated. Extensive pulverization (25min at 25Hz) of previously cooled samples (5min in liquid nitrogen) allowed for extraction in a phosphate buffer (pH 6) solution after 10min vortex agitation at room temperature, simplifying the coupling of the extraction to an effective mixed-mode SPE (solid phase extraction) clean-up procedure. The extraction optimization was performed with samples fortified by drug incorporation according to a published procedure involving incubation of blank matrices for 16days...

AIM: Ketamine is used for post-operative analgesia. There has been recent disruption in it's supply. It is usually prescribed by patient's weight (3 mg/kg in 50 ml 0.9% saline) at a rate of 1-5 ml/hr (1-5 microgram/kg/minute). To conserve ketamine supplies our policy was changed to a concentrated "standardised" concentration of ketamine (250 mg in 50 ml 0.9% sodium chloride) that could be run for a maximum of 72 hrs. There is evidence demonstrating no relationship between duration of infusion and microbiological contamination for 72 hrs...

Purpose. Methadone, a synthetic opioid agonist, is an effective alternative to strong opioids (morphine, hydromorphone, oxycodone, and buprenorphine) and is widely available as an oral formulation. Few data have been published so far on the use of intravenous (i.v.) methadone for the management of severe or refractory cancer pain. Methods. We followed 10 consecutives cancer patients with severe pain, treated with IV methadone. All had advanced disease and had already received strong opioids, some in association with ketamine...

Sanguinate, a polyethylene glycol-conjugated carboxyhemoglobin, was investigated for cerebral vasoactivity in healthy male Sprague-Dawley rats (Study 1) and for its ability to increase brain tissue oxygen pressure (PbtO2) after controlled cortical impact (CCI) - traumatic brain injury (TBI) (Study 2). In both studies ketamine-acepromazine anesthetized rats were ventilated with 40% O2. In Study 1, a cranial window was used to measure the diameters of medium - (50-100μm) and small-sized (<50μm) pial arterioles before and after four serial infusions of Sanguinate (8mL/kg/h, cumulative 16mL/kg IV), volume-matched Hextend, or normal saline...

BACKGROUND: Ketamine rapidly reduces thoughts of suicide in patients with treatment-resistant depression who are at low risk for suicide. However, the extent to which ketamine reduces thoughts of suicide in depressed patients with current suicidal ideation remains unknown. METHODS: Between April 2012 and October 2013, 14 outpatients with DSM-IV-diagnosed major depressive disorder were recruited for the presence of current, stable (≥ 3 months) suicidal thoughts...

Rhythmic slow waves characterize brain electrical activity during natural deep sleep and under anesthesia, reflecting the synchronous membrane potential fluctuations of neurons in the thalamocortical network. Strong evidence indicates that the neocortex plays an important role in the generation of slow wave activity (SWA), however, contributions of individual cortical layers to the SWA generation are still unclear. The anatomically correct laminar profiles of SWA were revealed under ketamine/xylazine anesthesia, with combined local field potential recordings, multiple-unit activity (MUA), current source density (CSD) and time-frequency analyses precisely co-registered with histology...
