Impairment of oxygen transfer in the lung by increasing oxygen concentration during halothane and trichloroethylene anaesthesia.
Two groups of 10 patients were studied during artificial ventilation with a mixture of oxygen, nitrogen and either halothane or trichloroethylene. Arterial blood and respiratory gas smapling was performed at FIO2 values of 0.33, 0.5 and 0.75. The efficiency of oxygen transfer, expressed as the difference between pulmonary end-capillary and arterial oxygen content, was found to decrease progress...
متن کاملRelationships between inspired oxygen concentration and venous admixture during nitrous oxide-oxygen-halothane anaesthesia.
The inspired oxygen concentration (F/O2) was changed on 43 occasions at about 30-min intervals in 13 patients during artificial ventilation with mixtures of nitrous oxide (N2O), oxygen and halothane. Ventilator settings remained unchanged for each patient and at the end of each period, samples of arterial and central venous blood (and, in six patients, pulmonary arterial blood) and inspired and...
متن کاملCerebral Blood Flow during Trichloroethylene Anaesthesia: a Comparison with Halothane.
Cerebral blood flow has been measured in dogs using the method of Ingvar and Lassen (1962) in which flow is calculated from the rate of clearance from the exposed cerebral cortex of krypton 85 after its injection into the carotid artery. It was found that the addition of trichloroethylene in concentrations of 0.4-0.9 per cent to a nitrous oxideoxygen anaesthetic mixture did not alter the cerebr...
متن کاملThe influence of halothane anaesthesia on oxygen toxicity.
Twelve dogs were anaesthetized with halothane and allowed to breathe spontaneously gas comprising either 100 per cent oxygen at 2 ATA (the test group) or 40 per cent oxygen/60 per cent nitrogen at 1 ATA (the control group). The control group survived to 24 hours without undergoing any significant change in cardiac output, pulmonary shunt ratio or A-a Po2 difference. The test group of animals di...
متن کاملThe effect of enteral oxygen administration on the hepatic circulation during halothane anaesthesia: clinical observations.
A study of the estimated hepatic blood flow (EHBF) using a colloidal gold technique in 28 patients undergoing saphenous vein stripping, showed that the EHBF decreased to 68% of its initial value during the period of halothane anaeshtesia and operation. When enteral oxygen was added EHBF increased to 82% of its initial value. An investigation in 14 other patients under going upper abdominal oper...
