Drugs used to facilitate sexual assaults are typically those that rapidly render the potential victim unconscious or sedated, and produce memory loss or amnesia. Many of these drugs are difficult to detect due to a delay in biological specimen collection. Detection is further hampered as the drugs are often administered in single low doses and are rapidly and extensively metabolized, resulting ...

Seismic analyses of methane hydrate data from the Blake Outer Ridge indicate high Pwave velocity and anomalously low S-wave velocity in sediments containing methane hydrates. In an attempt to explain this observed P-wave and S-wave velocity structure at the transition from gas to hydrates, the effect of different hydrate models on elastic moduli and velocities are explored. After construction o...

UNLABELLED The visually evoked potential (VEP) is an electrical signal generated by the occipital cortex in response to light stimulation of the retina. The clinical importance of the VEP consists in the diagnosis of optic nerve diseases and others ocular diseases. For experimental studies of VEP in experimental animals anesthesia is frequently required. Our study sought VEP changes depending o...

The purpose of this study was to compare the effectiveness of a chloral hydrate/hydroxyzine combination with and without meperidine in the sedation of pediatric dental patients. Twenty children were given 40 mg/kg chloral hydrate and 25 mg hydroxyzine, and 20 children were given 40 mg/kg chloral hydrate and 25 mg hydroxyzine and 0.5 mg/kg meperidine. All children were between the ages of 24 and...

introduction: the increasing use of diagnostic imaging in pediatric medicine has resulted in growing need for procedural sedation and analgesia (psa) to minimize motion artifacts during procedures. the drug of choice in pediatric psa was not introduced till now. the aim of the present study was comparison of oral chloral hydrate (och) and rectal sodium thiopental (rst) in pediatric psa. methods...
