Pituitary apoplexy resulting from hemorrhage or necrosis of a pituitary tumor with subsequent compression of the optic nerves and cavernous sinuses is a life-threatening condition. The diagnosis is made clinically by the sudden onset of headache, meningismus, visual impairment, and ocular abnormalities, Modern surgical techniques seem to have reduced morbidity. Nevertheless, it is evident that not every patient requires surgical decompression after pituitary apoplexy because of spontaneous resolution after hormonal replacement therapy. We report an 84-year-old man who had pituitary apoplexy presenting with headache, ptosis and eyelid swelling. A good result has been achieved with immediate replacement of steroid.

Background: During adult general anesthesia, we used 3~5 L/min of fresh gas flow(FGF) but low FGF are employed, the amount of anesthetic consumption and air contamination can be reduced. The aim of this study was to determine the minimal appropriate inflow rate of oxygen and nitrous oxide during semiclosed circle technique. Methods: We selected 40 patients, ASA group l or 2, scheduled for elective, nonabdominal surgery under general anesthesia with semiclosed circle system. Anesthesia was maintained with 50% oxygen, nitrous oxide and enflurane, controlled ventilation was used; rate of 10/min, tidal volume of 10 ml/kg. After induction and vital signs stabilized, FGF was changed to 4 L, 3 L, 2 L and 1L/min at interva1 of 30 minutes. We observed mean airway pressure and arterial blood gas tensions. Results: The changes of mean airway pressure did not correlated with fresh gas inflow rate. In arterial blood gas analysis, PaO showed a decreasing tendency significantly according to decreasing fresh gas inflow rate(p$lt;0.01) but there were no clinical hypoxemia in all patients. There were no significant changes in pH, PaCO₂ and base excess. Conclusions: We consider that FGF of 1-2 L/min is appropriate during adult general anesthesia because of economic and ecological advantages. Also, we consider low flow technique with below 1L/min can be used safely and effectively under proper gas monitoring such as oxygen analyzer capnometer.
