Interleukin-10 release related to cardiopulmonary bypass in infants undergoing cardiac operations
peer reviewed / To evaluate cytokine balance related to cardiopulmonary bypass, we prospectively investigated 11 infants undergoing cardiac operations for congenital heart disease. Proinflammatory cytokines (tumor necrosis factor- α and interleukin-8) and the antiinflammatory cytokine interleukin-10 were measured at multiple time points before, dur...
Pituitary-adrenal activity and opioid release in ponies during thiopentone/halothane anaesthesia
The effect of thiopentone/halothane anaesthesia on the release of endogenous opioid, adrenocorticotrophin, arginine vasopressin, cortisol and catecholamine was investigated in ponies. The contribution made by halothane itself was studied by maintaining six ponies with a constant 12 per cent end tidal halothane concentration and five with a concentr...

Epidural anesthesia impairs both central and peripheral thermoregulatory control during general anesthesia.
BACKGROUND: The authors tested the hypotheses that: (1) the vasoconstriction threshold during combined epidural/general anesthesia is less than that during general anesthesia alone; and (2) after vasoconstriction, core cooling rates during combined epidural/general anesthesia are greater than those during general anesthesia alone. Vasoconstriction ...
Clonidine and ketanserin both are effective treatment for postanesthetic shivering.
BACKGROUND: Although meperidine is an effective treatment of postanesthetic shivering, its mechanism of action remains unknown. Investigation of other drugs might help clarify the mechanisms by which shivering can be controlled. Accordingly, we investigated the efficacy of clonidine, an alpha 2-adrenergic agonist, and ketanserin, a 5-hydroxytryptam...
Halothane is less suppressive than pentobarbital on reflex and neural activation of pancreatic F-cell.
To determine the suitability of halothane anesthesia for studies of parasympathetic control of the endocrine pancreas in dogs, we assessed the effect of halothane on reflex, direct neural, and direct chemical activation of the parasympathetic input to the islet. Levels or output of pancreatic polypeptide (PP), an islet hormone under predominant cho...
Measurement of endocardial viability ratio (E.V.R.) during anesthesia for cardiac surgery
Since sub-endocardial ischemia is the consequence of a discrepancy between the blood demand and supply of oxygen at this level, the study of the myocardial performance by the measurement of the endocardial viability ratio (E.V.R.) is both useful and possible during anesthesia. E.V.R. is the ratio between the oxygen supply and demand of the myocardi...
