Brief Summary:
Hypotension during anesthesia often occurs because reduced systemic vascular resistance and blocked sympathetic nervous system by anesthetic drugs. In patients who are taking hypertension medication, blood pressure drops are exaggerated by inadequate compensation mechanism due to decrease of blood vessel elasticity and desensitization of baroreceptors. In one-lung ventilation (OLV) during thoracic surgery, persistent perfusion of non-ventilatory lungs can lead to increased intra-pulmonary shunt and hypoxemia. As a compensatory mechanism, the gravitational effect and hypoxic pulmonary vasoconstriction occur. Among these, hypoxic pulmonary vasoconstriction is associated with pulmonary vascular resistance. Norepinephrine and vasopressin, which are commonly used in patients with hypotension, affect systemic and pulmonary vascular resistance. However, no studies have been done on lung oxygenation and pulmonary mechanics of these vasoactive drugs in patients undergoing surgery on one lung. Therefore, the purpose of this study is to investigate the effects of vasoactive drugs, norepinephrine and vasopressin, in patients with hypertension.
