Scavenging 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 ...
متن کاملA simple T-piece.
THE value of the T-piece principle in reducing the resistance an anaesthetic apparatus offers to respiration is well established. Unfortunately the commonly used Ayre's (1937) T-piece cannot be connected directly to the endotracheal tube. The angled connectors and pieces of rubber tubing which must be interposed markedly increase the resistance of the apparatus to respiration. To overcome this ...
متن کاملFuzzy logic control of inspired isoflurane and oxygen concentrations using minimal flow anaesthesia.
In order to evaluate the performance of feedback fuzzy logic control of inspired oxygen and isoflurane concentrations, we studied 30 patients undergoing discectomy for lumbar (n = 26) or cervical (n = 4) disc herniation. Patients were allocated random to one of two groups: a standard group (n = 15) with low flow anaesthesia (1.2-1.3 litre min-1) and manual control of gas concentrations; and a f...
متن کاملDomiciliary oxygen concentrators in anaesthesia: preoxygenation techniques and inspired oxygen concentrations.
A conventional preoxygenation technique was compared in two volunteers with two techniques based on a drawover breathing system supplied with oxygen enriched air from a Devilbiss Mini VO2 domiciliary oxygen concentrator. Breathing from a 20-litre bag, filled previously at 2 litre min-1 from the concentrator was as effective as the conventional technique (PaO2 73.2 kPa). Supplying 4 litre min-1 ...
متن کاملInspired oxygen concentrations in semiclosed circle absorber circuits with low flows of nitrous oxide and oxygen.
Fresh gas flows of 1-5 l./min containing oxygen concentrations of 25-50% in nitrous oxide were led into a semiclosed circle absorber circuit. The resulting inspired oxygen concentrations were measured under conditions of spontaneous respiration. The lower the fresh gas flow, the greater was the discrepancy between fresh gas and inspired oxygen concentration. No association between minute volume...
