Abstract
- Mean arterial pressure, PaO2, PaCO2, pH, bicarbonate and base-excess in connection with disease and anesthetic periods were measured in 49 cases of open heart anesthesia which were perfarmed between 1976 and 1979 in the Department of Anesthesiology, Kyungpook National University School of Medicine. The following results were obtained in the mean values of total cases. Mean arterial pressure was decreased but PaO2 was progreasively increased with increased anesthetic time. PaCO2, was slightly decreased following anesthetic time, especially on total bypass. The pH was progressively increased from the time of partial bypass. Base excesa and bicarbonate were decreased before bypass but gradually increased from partial bypass and reached a peak after bypass. The TOF group showed the lowest values of mean arterial pressure, PaO2, and pH among the other groups, and resulted in the poorest patient's condition. In the other hand, the miscellaneous group showed the lowest values of PaCO2, no increased bicarbonate, and became the best condition among the other groups. Metabolic acidotic change persisted during the initial period but gradually changed to an alkaIotic tendency after bypass.
