[Intrapulmonary blood shunting during surgical interventions in children].
It has been observed that controlled lung ventilation during surgery in children is accompanied by an increase in intrapulmonary blood shunting, which averages 7.3% in urological surgery, 12% in abdominal surgery and 16.8% in thoracic surgery. The shunting is caused by ventilation-perfusion disturbances. The use of high-frequency jet ventilation, i.e. application of 16.7 Hertz oscillatory modulations together with conventional controlled lung ventilation enables one to decrease intrapulmonary shunting, reduce the signs of circulatory hyperdynamia and the load on the heart ventricles and leads to normalization of pulmonary flow in thoracic surgery.
