AbstractAbstract PDF
Before beginning the extracorporeal circulation, perfusionists should supply oxygen into the oxygenator and establish blood flow through the blood line of the heart-lung machine. But these manipulation can induce severe hypocarbic state of priming solutions due to wash out of CO2 gas in the solution. This study was carried out to examine the relationship of blood gas changes between hypocarbic priming solutions and body circulation in 15 patients undergoing open heart surgery with extracorporeal circulation. PaCO₂, pH, buffer base and PaO2 were measured from priming solutions before and 15 minutes after the extracorporeal circulation. The results were as follows; 1) Before the extracorporeal circulation, mean PaCO₂ level was 12.1±7.8 mmHg in the priming solution. However, 15 minutes after extracorporeal circulation, the PaCO₂ level was maintained at 35.7±5.7 mmHg. 2) pH in the priming solution was variable from 6.93 to 7.99 (mean 7.45±0.29), but after 15 minutes it was ranged from 7.28 to 7.42 (mean 7.35±0.05). 3) Mean buffer base level in the priming solution was 7.9±3.5 mmol/l. but after 15 minutes, it was 19.6±1.2 mmol/l. 4) Mean PaO₂ level in the priming solution was 667.1±45.6 mmHg, but after 15 minutes, it was 280.7±131.7 mmHg.

AbstractAbstract PDF
In the beginning of anesthetic training, one of the clinical practices that anesthetists have to learn is manually controlled ventilator techniques. The popularity of manually controlled ventilatory techniques has been gradually decreased with increased use for anesthetic ventilators. However it is important and basic for the anesthetists to master manually controlled ventilator techniques skillfully. Recently, we analyzed the arterial blood gas in 30 cases before and during general anesthesia, and studied the effects of the manually controlled ventilation on the pulmonary gas exchange. The results were as follow; 1) Mean value of PaCO₂ during the manually controlled ventilation, 29.9±2.0 mmHg was decreased statistically comparing with that of PaCO₂ before the anesthesia, 39.8±2.8 mmHg. 2) Mean values of pH and HCO₃⁻ during the manually controlled ventilation were 7.48±0.03, 22.2±2.4 mEq/1, respectively and values before the anesthesia were 7.41±0.02, 25.2±1.8 mEq/1, respectively. 3) Mean value of PaO₂ and O₂ saturation during the manually controlled ventilation were 270.0±28.8 mmHg, 99.6±0.2%, respectively and values before the anesthesia were 92.5±4.0 mmHg, 96.9±1.0%, respectively. These results indicates that manually controlled ventilation at our department of anesthesiology produced mild hyperventilatory state. However these were no significant changes in cerebral blood flow and other biochemical parameters.
