ABSTRACT
Objective:
Fetal monitoring is extremely important in perinatal care. Analysis of cardiotocogragh(CTG) can suppose if the fetus is lack of oxygen, distressed, acidosis, etc. in order to take measures timely.Methods:
We have designed Meticare analysis software package to analyze 867 pieces of CTG data, and researched the relationship between short term variation (STV) and basal heart rate(BHR) by statistics, and short time monitoring analysis based on STV.Results:
The amplitude of fetal heart rate curve variation(long term variation) tended to decrease when BHR increasing, with the negative correlation and regression equation STV = 9.866-0.02×BHR. Positive correlation exists between 5 and 10 mimute-STV, with the regression equation STV_(10min)=2.861-0.596×STV_(5min).Conclusion:
STV calculated by 5 minutes CTG data can forecast the one by 10 minutes data as a reference demanded by Dawes & Redman criterion. If fetal doppler contains STV analysis function, out-patient fetal heart auscultation will be more significant. After 30 weeks pregnancy, with the STV decreasing, fetal distress, asphyxia, low birth weight, and even mortality increasing. BHR increasing should cause attention that STV might decrease, when monitoring with no analysis functional devices or fetal dopplars.
