[Theoretical basis and clinical assessment of fluid evacuation from the lungs during bronchoalveolar lavage in children]. / Teoreticheskoe obosnovanie i klinicheskaia otsenka évakuatsii zhidkosti iz legkikh pri bronkhoal'veoliarnom lavazhe u detei.

The authors discuss the theoretical aspects of the process of lavage fluid absorption from bronchial and alveolar spaces during broncho-alveolar lavage. It is shown that pressure in the vessels of pulmonary circulation, the blood colloid osmotic pressure, and permeability of the alveolar-capillary barrier play an important role in the dynamics of changes of the absorption process. Methods for correcting the intensity of absorption (use of solutions of different osmotic force for lavage) are suggested. Data gained in observation over the use of therapeutic lavage in children confirm the theoretical conclusions and demonstrate the favourable results of lavage in children with atelectases.
