چکیده

The effect of isoflurane (Forane) anaesthesia and surgery on thyroid function was investigated in nine male patients. Isoflurane anaesthesia alone for 30 minutes prior to the start of surgery increased plasma triiodothyronine uptake (T3U) and thyroxine (T4) level by 18 and 20 per cent, respectively. Free thyroxine index (FTI) values in blood increased by 62 per cent during the same period. One hour of surgical procedure further elevated these parameters. Our data indicate that isoflurane anaesthesia and surgery increase circulating thyroxine in man.

Effect of isoflurane anaesthesia and surgery on carbohydrate metabolism and plasma cortisol levels in man.

The present study was undertaken to investigate in nine male surgical patients the effects of isoflurane anaesthesia alone on the carbohydrate metabolism by determining plasma growth hormone (GH), insulin, blood glucose, and cortisol, and to compare them with the effects of anaesthesia associated with surgical operations. Determination of plasma GH, insulin, cortisol, and blood glucose were mad...

Brit. J. Anaesth. (1972), 44,841 EFFECT OF ETHER, TfflOPENTONE ANAESTHESIA AND SURGERY ON PLASMA THYROID-STIMULATING HORMONE (TSH) LEVELS IN MAN

The thyroxine responses to ether, thiopentone anaesthesia and surgical operation have been reported by some investigators (Fore, Kohler and Wynn, 1966; Oyama et al., 1969a, b). However, no study has been made to evaluate the influence of these anaesthetic agents and surgery on pituitary thyroidstimulating hormone (thyrotropin=TSH) in man. The synthesis and secretion of thyroxine in the thyroid ...

Effect of althesin (CT-1341) on thyroid-adrenal function in man.

The effects of althesin on adrenocortical and thyroid function were investigated by measuring plasma concentrations of cortisol, thyroxine (T4) and free thyroxine index (FTI) in 29 surgical patients. Althesin did not change the plasma cortisol concentrations from the preanaesthetic control value; however, the concentrations increased significantly after the start of surgery and thereafter. Alth...

Effect of isoflurane on the auditory evoked response in man.

We have examined the effects of isoflurane (0.6-2.9% end-tidal) on the auditory evoked response (AER) in six patients before elective surgery. Isoflurane produced significant dose-related changes in the AER: reductions in amplitude and increases in latency of the cortical waves Pa and Nb, and increases in the latency of the brainstem waves III and V. When isoflurane was compared with halothane ...

Comparison of the effects of propofol and isoflurane anaesthesia on right ventricular function and shunt fraction during thoracic surgery.

I.v. anaesthetic agents, including propofol, have not been shown to inhibit hypoxic pulmonary vasoconstriction (HPV). This may encourage the use of propofol in thoracic surgery where one lung ventilation (OLV) is required. We have compared the effects of maintaining anaesthesia with either isoflurane or propofol infusion on right ventricular function and shunt fraction. We studied 10 patients w...
