ABSTRACT
Objective To explore the security of spinal anesthesia by observing the pefioperation serum troponin T in the elderly patients with coronary heart disease who underwent spinal anesthesia.Methods 40 case8 were divided into two groups according to the elderly patients with or without the history of coronary heart disease.Group Ⅰ 0f 20 cases were the patients with the history of coronary heart disease.Group Ⅱ of 20 cases were the patients without the history of coronary heart disease.Both groups were undertaken single spinal anesthesia combined with epidural anesthesia.The blood samples were collected at the time of perioperation,the end of the operation and 24 hours after surgery.The serum troponin T Was tested by Roche fully automated ehemiluminescent analyzer E170.The symptoms and signs of the coronary heart disease in the patient were observed.And the age,operation time,anesthesia lever,the amount of bleeding and transfusion were recorded,and at the same time,electrocardiogram,heart rate,pulse,cerebral oxygen saturation were monitored.Results There was no significant difference between two groups in age,operation time,anesthesia lever,the amount of bleeding and transfusion,heart rate,pulse,cerebral oxygen saturation.There was no significant difference between two groups in seram troponin T.No symptoms and signs of the coronary heart disease were observed in two groups.There Was no significant difference between two groups in constituent ratio of positive rate of serum troponin T.There was one case in each group that serum lroponin T was more than reference value (0.010μg/L)during the perioperation while the patient was no discomfort.Conclusion Spinal anesthesia has no impact on the change of perioperative 8ertlm troponin T in the elderly patients with coronary heart disease.
