Partial liquid ventilation in normal rabbits: comparison of three kinds of perfluorocarbon.
Perfluorocarbon liquids have been used in liquid ventilation studies and considered an effective technique of gas exchange with less barotrauma when compared with gas ventilation. We compared the effects of partial liquid ventilation (PLV) using 3 kinds of perfluorocarbon liquids (Fluorinert FC 43, FC 77 and FC 84) available in Taiwan in normal rabbits. We were able to achieve adequate oxygenation and ventilation during a 2-hour-duration of PLV using FC 43, FC 77 or FC 84. There was no significant difference in hemodynamic status or laboratory findings between control group and PLV groups. There were also no significant differences before LV and after 2 hours of PLV among PLV groups. Histological study of lung tissue revealed intact and well expanded alveoli, and no significant pathological change after 2 hours of PLV. These results show that PLV using FC 43, FC 77 or FC 84 is an effective technique for maintaining adequate pulmonary gas exchange in normal rabbits.
