The paper presents a review of literature concerning the use of Doppler technique in the evaluation of pulmonary blood flow. Especially, it is important to monitor the development of lung in suspicion of lung hypoplasia that closely correlates with abnormal development of pulmonary vessels. In the literature there are single reports pointing on its usefulness in the detection of lethal lung hypoplasia. It has been suggested that this technique may provide valuable information of the development of vascular bed in lung. Recent data concerning Doppler blood flow velocimetry in hypoplastic lung stimulate to further studies suggesting their significant value in the diagnosis and distinguishing the lethal form of pulmonary hypoplasia.

At patients threatened with premature childbirth the influence of glicocorticoids on short and tong-term fetal heart rate variability and the occurrence of respiratory arrhythmia was evaluated. It has been ascertained statistical significant lowering of the incidence of fetal respiratory arrhythmia and short-term variability. Described changes had a temporary character and surrendered of normalization in the course 72 of hours after last use of glicocorticoids. The influence of glicocorticoids on select biochemical and biophysical parameters of state pregnant women was also studied. One specified occurrence of incidental symptoms in road drove of therapy. Pregnant women in road of treatment glicocorticoids have also observed a temporary weakness of feeling of fetal movements.

The use of vesicoamniotic shunt in the case of obstructive uropathy was described. On the base of ultrasound screening it has been diagnosed urethral obstruction. This abnormality of urinary tract was found in male fetus. It has been diagnosed the posterior urethral valve. Qualification to intrauterine therapy was based on normal parameters of renal function. Under ultrasound guidance the vesicoamniotic shunt was installed. The normal drenage was observed within 6 weeks, until it was dislocated. In 36th week of gestation the cesarean section was performed. The indications were signs of urethral obstruction. The boy was born in whom posterior urethral valves were recognized. He was born in good condition without any biochemical features of renal damage as well as signs of hypoplastic lung.
