Muscarinic receptor subtypes modulate the release of [3H]-noradrenaline in rat spinal cord slices.

Spinal muscarinic receptors are involved in the mediation of antinociceptive effects. The modulation of noradrenaline (NA) release on muscarinic receptor subtypes in the rat spinal cord was investigated in in vitro perfusion experiments. After rat spinal cord slices were preincubated in [3H]NA, the slices were perfused with a superfusion apparatus.

[Bispectral index monitoring during anesthesia with propofol for electroconvulsive therapy].

We studied the changes in the bispectral index (BIS) of 22 patients during electroconvulsive therapy (ECT) under propofol and succinylcholine anesthesia. BIS values (mean+/-SD) were 94+/-4 before anesthesia, 51+/-15 before ECT, 49+/-20 after ECT, and 60+/-17 at complete re-awakening. The BIS values at re-awakening were significantly different from those before anesthesia (P<0.

Endogenous opioids and epinephrine in nitroglycerin provocation tilt test in patients with neurally mediated syncope.

Endogenous opioids and catecholamines are involved in autonomic activity. Nitroglycerin provocation tilt is a useful modality for evaluating neurally mediated syncope. Endogenous opioids and epinephrine might play an important role in nitroglycerin provocation tilt.

[The effectiveness of perioperative intravenous flurbiprofen in minor ear, neck and nose surgery].

To evaluate the effect of perioperative intravenous administration of flurbiprofen, a nonsteroidal anti-inflammatory drug, on the postoperative pain after minor ear, neck and nose surgery, eighty patients were randomly allocated into three groups. Control group of 40 patients, received a placebo. The second group (n = 20) received 1 mg.

[The changes of bispectral index induced by administration of midazolam during propofol anesthesia].

The effect of the additional administration of midazolam or flumazenil on bispectral index (BIS) during propofol anesthesia was investigated in 22 scheduled surgical patients. Midazolam 10 or 30 micrograms.kg-1, or flumazenil 6 or 12 micrograms.
