Clinical Analysis of Non-specific Antihypertensive Effect after Theoperation of Esophago-Cardiac Cancer by Hypertension

Objective To study the reason and mechanism of nonsecific antihypertensive effect after the operation of esophago-cardiac Cancer by hypertension. Methods Diastolic pressure(Dp) was higher than 14.7kpa or systolic pressare (SP) was higher than 24kpa thay reciped antihyperten sive Drugs before the operation or thay were intravanous dripped Nitrogly-Cerinum.during the operation for deliberate hypotension. Results There were 58 cases in this group after the operation.DP was lowered below 12.6kpa.SP was lowered 12%～18%.The effect were lowered in association with blood prassure of fore-operation. Conclusion The following four were reason and mechanism of non-specific antihypertensive effect after the operation of esophago-cardiac cancer by hypertensicn:①thay were done weay with stressor and stress resspones.②anemia lead to blood wiscosity lowered.③intrapulmonary-stomach stimulused aortic arch and heart lung baroreceptor so antihypertensive reflex increased.④the secrine of vasodilator matter increased and the secrine of vasoconstrictor matter decrased.
