Lack of anxiolytic effect of diazepam in pre-anaesthetic medication.
In 30 female patients undergoing elective cholecystectomy, we have compared the anxiolytic effect of diazepam 10 mg with placebo, using measurements of cardiovascular (arterial pressure and heart rate), biochemical (plasma concentrations of noradrenaline, adrenaline, cortisol and dopamine beta-hydroxylase), subjective (visual analogue scale) and behavioural (Hamilton anxiety test) variables. Pr...
متن کاملSpontaneous ventilation with the Bain anaesthetic system.
Measurements of ventilation and of inspired gas composition were made while volunteers breathed a non-anaesthetic gas through a Bain anaesthetic system. It was found that rebreathing occurred when the fresh gas flow was between two-and-a-half and three times the minute volume. Fresh gas flows at least three times the minute volume appear to be necessary to prevent rebreathing when using this sy...
متن کاملLack of correlation between the anaesthetic and anti-convulsant potencies of althesin, ketamine and methohexitone.
Using Sprague-Dawley rats, the anti-convulsant potencies of Althesin, ketamine and methohexitone were determined for bicuculline-and strychnine-induced seizures and compared with their effects on hyperbaric seizures. All three anaesthetics protected against both types of chemical convulsants; the degree of protection varied from 34 to 151%, with Althesin being the most effective. However, there...
متن کاملImproving the efficiency of the drawover anaesthetic breathing system.
We investigated modifications to the reservoir tube usually used in drawover anaesthetic breathing systems as a method of improving its efficiency and performance. The resulting oxygen concentration was recorded at different oxygen flow rates whilst an artificial lung was being ventilated over a range of minute volumes. Addition of a reservoir bag and valves significantly increased the measured...
متن کاملScavenging of anaesthetic gases using the double T-piece system.
fully expected but it is inappropriate, for the following reasons: Considerably less halothane is given when a caudal block is performed than during a general anaesthetic alone. After the blocking procedure, just sufficient general anaesthetic was given to prevent the child from disturbing the surgeon. For this purpose nitrous oxide in oxygen was sufficient in the majority of patients. It does ...
