Intravenous oxygenation with lactated Ringer's solution.
This experimental work was performed on 4 rabbits to demonstrate that administrations of oxygenated Ringer's lactate through the central venous infusion could be used as a means of oxygenation. The oxygen tensions of Ringer's lactate were determined upon changing the amount of oxygen being bubbled and the solutions with the mean PO2 and pH of 575.5 mmHg and 6.34 were used in this study. We did not use the solutions having the values below 416.6 mmHg PO2 and pH 6.08. After the infusion of the oxygenated solution through central vein, PaO2 values throughout the 1 hour experimental procedure were significantly increased above the control value. Other parameters such as pH, PaCOs, HCO3-, BE, O2 saturation did not show any statistically significant changes. Some degree of oxygenation could be obtained by infusing the oxygenated Ringer's solution. This suggested that oxygenation by infusion through the central venous line could used clinically in the treatment of some forms of hypoxia with hypovolemia.
