Aim of investigations was qualification of account between Doppler parameters in estimation of fetal state. Investigations one passed on 30 fetuses and newborn children in pregnancies brought. Doppler parameters one priced at use of sonographic device Toshiba SSH 140 A/G and searchers of type convex about working frequency 3.75 MHz. Following Doppler flow blood parameters were analyzed: maximum blood speed (V1) average blood speed (V2) and minimum blood speed (V3), systolic/diastolic ratio (S/D), resistance index (RI), pulsatile index (PI) and proper flow in umbilical cord vein (MF) in following dishes of feto-placental circulation: middle cerebral artery (MCA) and umbilical cord artery (UA). Acid-base equilibrium and gasometry of blood in umbilical cord dishes one marked at use of device Ciba-Corning 278 Blood Gas System and parameters of oxygenation of blood at use of device Ciba-Corning 270 CO-OXIMETER. At new-born children one priced pH-metry (pH) and gasometry (pO2, pCO2, BAA) in blood umbilical cord arterial and venous were measured. The newborn children were estimated by Apgar score. There were following essential statistical correlations between Doppler parameters of fetal blood flow and with parameters of acid-base equilibrium of new-born child: 1/ between V2 and V3 in UA and with supply of rules (BAA) in UV (p = 0.027; p = 0.009) and UA (p = 0.035; p = 0.003) and venous pH (p = 0.022; p = 0.009); 2/ between RI in UA and BAA in UV (p = 0.006) and UA (p = 0.010); 3/ between PI in UA and BAA in UV (p < 0.0001) and UA (p < 0.0001) and pH venous (p < 0.0001). We can conclude that Doppler investigations only by measure of parameters of blood flow in middle cerebral artery and umbilical artery in expectation of state of birth new-born child priced across parameters of acid-base equilibrium and Apgar score are not very useful, however they are helpful. |
