It has been emphasized that continuous monitorings of arterial pressure, central venous pressure, electrocardiogram, blood gas analysis, serum electrolytes, body temperature, hematacrit and urinary output are mandatory for the anesthetic management of pheochromocytoma. In addition, it is necessary for the anesthetists to understand pharmacologic effects of drugs which influence the peripheral vascular tone and cardiac excitability. We experienced recently anesthetic management of two cases of pheochromocytoma; one raised problems of ventricular arrhythmias and hypertension that aggravated nature of arrhythrmias by increasing blood pressure and responded favorably to treatment with propranolol and trimetaphan. Tumor of this case originated from abdominal aortic wall. The other was managed by injection of d-tubocurarine which induced narrowing of pulse pressure by depletion of increasing systolic pressure and accompanied tachycardia without cardiac decompensation. We have reported proper anesthetic managements of two cases of pheochromocytoma with N2O O2-halothane anesthesia and reviewed literatures in discussion.

급성 수혈시 수혈 및 수액요법이 혈액응고기전(血液凝固機轉)에 미치는 영향에 관한 실험적 연구
염광원,김광우,곽일용,장호단 대한마취과학회 1972 Korean Journal of Anesthesiology Vol.5 No.1
Fourty-eightmongrel dogs were bled to half the level of their control aystolic blood pressures and infused with Hartmanns solution, low molecular weight dextran, whole blood, or with Hartmann's solution, low molecular weight dextran (1:1 or 1:3) in the amount equivalent to the blood loss. Bleeding time, coagulation time, platelet count and erythrocyte sedimentation rate were examined 6 hours and 24 hours after the completion of infusion. The results are as follows: 1) No changes in blood coagulability other than due to hemodilution were observed in dogs infused with Hartmann's solution, whole blood, or 1: 1 Hartmann's solution+low molecular weight dextran. 2) Significant changes in blood coagulability were noted, however, in dogs infused with low molecular weight dextran alone or 1:3 Hartmann's solution+low molseular weight dextran. These changes seem to be related rather to decreased platelet function than to the decease in platelet number.

Hdroxyethyl Starch(HES)가 혈액응고에 미치는 영향
신광일,김광우,김용락,곽일용,최수홍,장호단 대한마취과학회 1973 Korean Journal of Anesthesiology Vol.6 No.1
To determine the effects of hydrcxyethyl starch upon liver, kidney, serm electrolytes and particularly upon blood coagulation, 500 ml of 6% HES in saline solution was administered intravenously to 15 patients during elective minor surgery. In all cases weighted blood loss was less than 600 ml without replacement. The following laboratory tests were performed immediately before infusion and again 1 hour, 24 hours, 48 hours, and 1 week after the infusion: RBC, WBC, hemoglobin, hematocrit, ESR, platelet, bleeding time, coagulation time, prothrombin time, total protein, albumin, total bilirubin, direct bilirubin, SGOT, SGPT, alkaline phosphatase, BUN, sodium, potassium, and chloride. The results are as follows: 1) No anaphylactic shock or bleeding tendency characteristic of colloids was encountered. 2) No functional disturbance of liver or kidney directly attributable to HES was identified. 3) All laboratory parameters except WBC and ESR decreased after infusion. The decrease was, however, within the normal range and believed secondary to dilational effect of infusion. WBC increased somewhat, but returned to the preinfusion level in a week. 4) Exceptionally erythrocyte sedimentation rate increased notably during the 24 hour period following infusion. As with dextran, this was interpreted not due to direct effect of HES, but due to increased adsorption of fibrinogen, α-β-γ-glcbulin to red cell surface with changes in electric charge between red cells. 5) Clinical applicability, metabolic aspect, degree of subtitution of hydroxyethyl group and safety with multiple infusion of HES must be carefully determined.
