title: [Validity of cardiotocography in acute fetal hypoxia--neonatal status after cesarean section].
abstract: OBJECTIVE
  Judging the validity of CTG monitoring as a method of acute foetal hypoxia diagnosis (AFH), quantifying the number of cesarean section (SC), performed from the indication of acute fetal hypoxia and point out a number of surgeries based on false positive CTG results.
  
  
  METHODS
  Retrospective study.
  
  
  METHODS
  1st Department of Obsterics and Gynaecology Faculty of Medicine MU, Brno.
  
  
  METHODS
  100 women, patients of the 1st Department of Obstetrics and Gynaecology in Obilní trh, Brno, who had cesarean section due to foetal hypoxia indicated on the base of pathological or suspect CTG, were involved in the collection. In the next stage newborns were divided into 2 clinical groups: "Acidosis" and "Normal" depending on the pH value from a. umbilicalis and statistically analysed.
  
  
  RESULTS
  From 100% suspect or pathological CTG, only 36.19% were valid (newborns showed depression after birth). Remaining 63.18% of newborns, although showed CTG signs of hypoxia were born normal and probably were not necessary to be born by cesarean section.
  
  
  CONCLUSIONS
  Although CTG investigation is in most places the only "objective" method for diagnosis of AFH, this investigation cannot precisely determinate whether hypoxia is present or it is not. For true objectivity of foetal intrauterine condition and correct indication of SC is suitable to use further diagnostic methods of AFH in future, for example intrapartal foetal pulse oximetry or blood analysis from foetal scalp.
