Assessment of fetal reserve in the perinatal period / 中国实用妇科与产科杂志

It is crucial to assess the fetal reserve function and intrauterine health status before and during labor,based on antenatal high risk factors and fetal surveillance methods such as intrapartum electronic fetal monitoring and fetal scalp stimulation,which can guide clinicians to intervene in a timely and effective manner,thus avoiding adverse outcomes due to fetal hypoxia.

Labor Admission Test And Neonatal Outcome

Purpose: Purpose of the study is to study the Mode of Delivery and Perinatal outcome in relation to the admission test in the study group . Method: All women in latent phase of labor were subjected to admission test with CTG machine and tracing recorded. Any complication arising during labor and the perinatal out come were recorded. Results: Incidence of fetal distress, need for operative delivery, low apgar scores, low birth weight, admission to NICU and perinatal deaths are significantly more in non reactive admission test group. Conclusion: Admission test is economical, non invasive, and readily available screening test. Non reactive patterns predicts well the incidence of perinatal complications and Neonatal mortality.

Development and Effects of Supplementary Material about Electronic Fetal Monitoring for Nursing Students

PURPOSE: This study aimed to develop supplementary material about the electronic fetal monitoring for nursing students, and to test the effects on electronic fetal monitoring related knowledge and confidence on nursing performance in delivery room. METHODS: Totally 58 nursing students were recruited either experimental group (n=30) or a control group (n=28). A non-equivalent control group pretest-posttest design was employed to test the effects on fetal monitoring related knowledge and confidence on nursing performance in delivery room. The supplementary material about the electronic fetal monitoring was developed based on Analysis, Design, Development, Implement and Evaluation (ADDIE) model. Fetal monitoring related knowledge and confidence on nursing performance in delivery room were self-reported by the scales that author developed. Data were collected at pre-test and after the 6-week intervention. RESULTS: There was significant difference in confidence on nursing performance in delivery room between two groups after intervention. CONCLUSION: These findings suggest the importance of the supplementary material about the electronic fetal monitoring for nursing students to improve confidence on nursing performance in delivery room.

Nonlinear Dynamic and Chaotic Analysis of Fetal Heart Rate in Fetal Distress / 대한산부인과학회잡지

OBJECTIVES: For estimating the antenatal fetal wellbeing to develop new analysis method of fetal heart rate(FHR) with electronic Fetal Heart Rate Monitoring(eFHRM) and computer. METHODS: Heart rate signal is received from distressed fetus using eFHRM. It is necessary to carry out low pass filtering as a preprocess for the nonlinear method. Nonlinear parameters are calculated and classified to investigate the relations between these parameters and values of umbilical cord blood gas. RESULTS: By dividing values of the umbilical cord blood gas into 5 fetuses of acidemic group and 17 fetuses of non-acidemic group after 22 neonates who presented fetal distress were born, the following results as compared with nonlinear chaotic analysis result were obtained. 1. Delay time through AMI for acidemic group was 16.80+/-3.11, and was higher than 15.41+/-2.27 for non-acidemic group, and is not significant in statistics. 2. Embedding Dimension calculated with FNN method was 5.60+/-2.07 for acidemic group, and 4.71+/-1.26 for non-acidemic group, and it was not significant statistically. 3. Correlation dimension for acidemic group was 1.41+/-0.20, and was higher than 1.10+/-0.38 for non-acidemic group, and is not significant in statistics. 4. Mean crossing value by isoangular return map was 28.80+/-11.34 for acidemic group, and 16.65+/-7.00 for non-acidemic group, and it was significant statistically(P=0.008). 5. In comparison of information entropy in 1-D ED, acidemic group was 6.32+/-0.38 and non-acidemic group was 6.20+/-0.28 and it was not significant statistically. Also, in comparison of value in 2-D ED, acidemic group was 10.20+/-0.34. It was higher than non-acidemic group of 9.51+/-0.43 significantly in statistics(P=0.004). But, in comparison of value in 2-D EP, acidemic group was 8.78+/-0.86 and non-acidemic group is of 9.22+/-0.74 and it wasn't significant statistically. And, 2-D ED(DI) value was 10.64+/-0.14 for acidemic group and 10.51+/-0.18 for non-acidemic group, and it wasn't significant statistically. CONCLUSIONS: By the above result, nonliner dynamics and chaotic analysis of heart rate data with computer can serve as a new diagnosis method which may estimate the fetal wellbeing with real time. Through further studies for establishment of diagnosis standard and computer programming, real time diagnosis method shall be applied to clinical practice.

Correlation of electronic fetal monitoring, amniotic fluid index and doppler velocimetry with cord pH in hypertensive pregnant women (a 3 year review at PCMC)

Forty-four hypertensive patients underewent electronic fetal monitoring, amniotic fluid index assessment and doppler velocimetry studies of the umbilical artery prior to delivery. Cord pH at birth of the babies were correlated with antepartum assessment. Forty five percent of the babies had a cord pH of less than 7.15 correlation of CTG with cord pH had a correlation coefficient of .0752. Amniotic fluid index with cord pH, correlation coefficient was .0344 and Doppler Velocimetry with cord pH, correlation coefficient was 0.024.
