BACKGROUND AND OBJECTIVE The combination of alfentanil-propofol or remifentanil-propofol provides adequate conditions for tracheal intubation without neuromuscular blocking drugs in most patients, but hypottension can occur during induction of anesthesia with propofol. We compared clinically acceptable intubating conditions and cardiovascular responses to induction and endotracheal intubation i...

Background: Thiopental has been used as a pharmacological cerebral protection strategy during carotid endarterectomy surgeries. However, the optimal dosage required to induce burst suppression on electroencephalogram (EEG) remains unknown. This retrospective study aimed determine of thiopental non-shunt endarterectomy. Methods: The...

The methanolic leaf extract of Thuja occidentalis was evaluated for possible sedative activities in mice. Sedative activity was evaluated by using hole cross, open field, thiopental sodium-induced sleeping time and elevated-plus maze (EPM) tests at 200mg/kg and 400 mg/kg.  The extract decreased the locomotor activity of mice in hole cross, open field and EPM test and showed the remarka...

Objective: Barbiturates have been demonstrated to reduce intracranial pressure (ICP), but adverse effects, which include hypotension and a long recovery time, make clinical applications difficult. Propofol is also known to have same effect. In the present study, we undertook coma therapy using propofol or barbiturate and compared clinical value in the practical point. Methods: From June 2004 to...

AIMS To determine the effects of premedication with thiopental on heart rate, blood pressure, and oxygen saturation during semi-elective nasotracheal intubation in neonates. METHODS A randomised, placebo controlled, non-blinded study design was used to study 30 neonates (mean birthweight 3.27 kg) requiring semi-elective nasotracheal intubation. The babies were randomly allocated to receive ei...

BACKGROUND Neuronal nicotinic acetylcholine receptors (nAChRs) are widely expressed in the central and autonomic nervous systems. The authors have previously shown that depressant and convulsant barbiturates both inhibit the ganglion-type nAchRs in PC12 cells. However, the central and gangliontype receptors have different subunit composition and pharmacologic properties. In this study, the auth...

BACKGROUND Lethal injection for execution was conceived as a comparatively humane alternative to electrocution or cyanide gas. The current protocols are based on one improvised by a medical examiner and an anesthesiologist in Oklahoma and are practiced on an ad hoc basis at the discretion of prison personnel. Each drug used, the ultrashort-acting barbiturate thiopental, the neuromuscular blocke...
