Circulatory effects of controlled arterial hypotension with trimetaphan during nitrous oxide-halothane anaesthesia.
Studies were made in ten patients of the circulatory changes occurring during the administration of trimetaphan to produce hypotension during nitrous oxide/halothane anaesthesia. Ventilation was spontaneous throughout. There were significant falls in arterial pressure and peripheral resistance. Cardiac output was relatively unaffected. Heart rate sometimes increased and this was associated with...
متن کاملCirculatory effects of pentazocine and pethidine during general anaesthesia with nitrous oxide, oxygen and halothane.
Pentazocine 30 mg and pethidine 30 mg were given intravenously to two groups of patients receiving general anaesthesia with nitrous oxide, oxygen and halothane. The injections were repeated after 10 minutes. The effects on cardiac output, arterial blood pressure, heart rate and central venous pressure were measured. Both drugs caused a transient fall (approximately 20 per cent) in cardiac outpu...
متن کاملEffects of nitrous oxide on respiration during halothane anaesthesia in the dog.
The pattern of ventilation was studied in eight greyhounds anaesthetized with halothane in 50% oxygen with nitrogen and in eight with the same concentration of halothane in 50% oxygen with nitrous oxide. There was a significant reduction in both inspiratory and expiratory times in the animals breathing nitrous oxide and an increase in the negative pressures developed in the obstructed airway du...
متن کاملCerebral circulatory and metabolic effects of hypotension produced by deep halothane anaesthesia.
Hypotension to a mean blood pressure of 33 mmHg for periods of 70 to 187 minutes was induced by increasing the inspired halothane concentration in 11 baboons which were already anaesthetized with 0·5% halothane, nitrous oxide, and oxygen. During hypotension, cerebral blood flow, measured by Xenon clearance and by a carotid electromagnetic flowmeter, decreased by more than half, and sagittal sin...
متن کاملSystemic effects of nitrous oxide when used with halothane and oxygen anaesthesia at normal body temperature.
driven in until it strikes the trachea, it is then withdrawn 0.5 cm and directed in the same direction as the trachea. Figure 3 in the article makes this point easier to follow. It is possible then to have a bicarotid and a superior vena caval cannula in the one animal. I am interested to hear that little postoperative respiratory trouble occurs in experimental pigs in England. This is probably...
