Aim. The evaluation of the effect of transfer and its distance with respect to the cardiovascularsystem and its complications such as peri/intraventricular haemorrhages.Material and methods. Enrolled in the study were all preterm newborns with the developmentlevel of ≤30. week of gestation (g.w.), born from 01/06/2006 to 31/12/2008 and admitted tothe Clinic within the first 72 hours of life. For the purpose of the comparison of the quali-tative variables Fisher’s test of the chi-square test for trend were applied, while for quanti-tative variables – Student t test was used. The model of logistic regression was also estimated.Results. Cardiovascular insufficiency eligible for treatment was diagnosed in 50 patients, whichto 65% of the examined population. The risk of cardiovascular insufficiency is 3,77-fold higherfor newborns transferred over a distance of < 20 km and 5.28-fold higher for newborns trans-ferred over 20-100 km as opposed to newborns transferred within a distance < 1km. In neo-nates affected by cardiovascular insufficiency peri/intraventricular haemorrhages occurred atrate higher with a statistical significance, including the most severe cases, i.e., of the III orIV degree (48%) as opposed to 4% in a group who did not require any treatment (p<0,001).Conclusions. The key risk factors of hypotension include: gestational age, body weight as wellas transfer of newborns; This demonstrates the necessity to perform transfer “in utero” in caseof pregnancies below < 30. week of gestation. In a group of newborns affected by cardiova-scular insufficiency IVH of the III or IV degree, likely to affect the infants’ further develop-ment, occurred at a rate higher with statistical significance.
