Clues as to the causation and treatment of hypotension during general anesthesia were sought in a study of the concentration of catechol amines in the plasma. An initial blood sample was taken just before induction and a second sample about an hour after the induction of light surgical anesthesia. The concentrations of epinephrine and norepinephrine in the plasma were determined thus in 47 patients who received general anesthesia and in 9 who received spinal anesthesia. Because of the magnitude of the normal variations and the smallness of the groups, however, no statistically valid conclusions were possible. The data obtained in this study did not confirm the reports of earlier investigators. The rises in catechol amine levels with use of ether and halothane were only suggestive, and the data did not afford any basis or theories as to the hemodynamic effects of the anesthetics used. |
