Abstract: To assess clinical correlation between pathological changes of the RCF (fetal heartbeat) - during labor and maternal-fetal changes depending on time of extraction the fetus (cesarean). The correlation between fetal suffering and installation time intervention (birth or cesarean operation) was studied on 33 parturient SUUB hospitalised in the period 2005-2008, which presented as common feature seriously altered fetal status at birth (Apgar score <7) - translated by severe respiratory distress that required ventilation. Blood samples were taken from the radial artery immediate postpartum and then every 8 hours. Of the 33 ventilated newborn babies, 28 were recovered and 5 died, noted that one infant was premature, others had normal birthweight. The exitus occurred in 24-72 hours post partum, Apgar score ranged 1-3 1 ‘and did not exceed 3 to 5’. Changes recorded in FHR: tachycardia - 3 cases, moderate bradycardia - 7, severe bradycardia - 3, early deceleration - 1, late deceleration - 19. Time to acidosis in 50% of fetuses is significantly shorter in case of late deceleration (115 min) than in the case of variable deceleration (145 min) or flat route (185 min). This study confirms the temporal relationship between the onset of pathological changes of the FHR and metabolic acidosis. The longer the extraction time the worse fetal prognosis.
