S. Klinzing et al., One-lung flooding for video-assisted thoracoscopic surgery in animal experiments on pigs - oxygenation and intrapulmonary shunt, RES EXP MED, 199(6), 2000, pp. 333-340
Unilateral flooding of the lung after intubation with a double-lumen tube m
akes intraoperative sonography of the lung during video-assisted thoracosco
pic surgery possible. After flooding with 15 ml/kg, the arterial partial ox
ygen pressure (with FiO(2)=1.0) is higher than that in total atelectasis by
about 100 mmHg, while it is only slightly less than that during bilateral
lung ventilation. Compared to total atelectasis, lung flooding reduces the
pulmonary right-to-left shunt volume. The pulmonary function normalizes wit
hin 8 h after the operation.
