[Comparison between computerized cardiotocography analysis in triplet and singleton pregnancies].

OBJECTIVES: Triplet pregnancies have higher perinatal morbidity and mortality rates than singleton pregnancies. In modern perinatology computer cardiotocography is one of the best methods of fetus state assessment. DESIGN: The research was based on computer analysis of cardiotocograph printouts. MATERIALS AND METHODS: The studies were made on 39 pregnant women in 27-36 week of gestation. The women were hospitalized in the Clinic of Perinatology I Department of Gynecology and Obstetrics, Medical University of Lodz and divided into two groups. First consisted of 30 singleton, second of 9 triplet pregnancies. RESULTS: Computer analysis of cardiotocograph printouts was performed and compared between the triplet and singleton pregnancy groups and presented in forms of tables. CONCLUSIONS: In the studded group of triplet pregnancy statistically significant higher number of high episodes, accelerations, fetal movements and signal loss were observed. The Apgar score and arterial cord pH was not different between the both groups.

[Monitoring of labour and delivery in the presence of meconium stained amniotic fluid by pulse oximetry].

OBJECTIVES: Evidence of meconium-stained amniotic fluid during labor suggests implementation of close monitoring of fetal well-being. DESIGN: Our purpose was to compare fetal oxygen saturation between cases with normal and meconium stained amniotic fluid. MATERIALS AND METHODS: Fetal oxygen saturation was continuously recorded with use of Nellcor N-400 fetal pulse oximeter in 30 control cases of term labour of normal, and 30 cases of meconium stained amniotic fluid. Distribution of fetal oxygen saturation values during 5 periods of labour was analyzed and compared between the examined groups, and presented in forms of Tables, together with neonatal umbilical artery pH values, Apgar score, birth weight and percentage of caesarian sections performed. RESULTS: No significant differences in fetal oxygen saturation, neonatal umbilical artery pH, birth weight and caesarian sections rate were observed between analyzed groups. Newborns 1-th minute Apgar score (mean value) and base excess was lower in meconium group compared to control group. CONCLUSIONS: Our data demonstrate, that fetal oxygen saturation trends to decrease during labour in fetuses in both groups.

[Usefulness of the examination of fetal blood oxygen saturation (FSpO2) and fetal heart rate (FHR) as a prognostic factor of the newborn outcome].

OBJECTIVES: Cardiotocography has become the standard for fetal monitoring in labor. False-positive findings during electronic fetal heart rate monitoring may were not associated with neonatal acidemia. Because of the poor specificity of fetal heart rate monitoring in predicting fetal distress, new methods are being investigated as a way to improve the accuracy of assessing the infant's condition during labor. DESIGN: The aim of this study was to determinate the efficiency of fetal blood oxygen saturation (FSpO2) and computer analysis of the fetal heart rate (Co-CTG) in the late 1-st stage of labor as a prognostic factor of newborn acidemia. MATERIALS AND METHODS: Total 62 subjects were studied. During labors and deliveries fetal oxygen saturation was continuously recorded, with use of Nellecor N-400 fetal pulse oximeter and continous CTG were performed by Hewlett Packard 50A. Transdermal fetal oxygen saturation measurements and CTG results obtained during the labors was analyzed using MONAKO system (ITAM Zabrze). The results were compared with the values of pH and base deficit in the umbilical artery measured just after delivery. RESULTS: The sensitivity, specificity, negative, positive predictive values and Youden factor based on FHR and FSpO2, for prognosis of neonatal acidosis were: 65%, 80%, 16%, 97.5% 60% and 0.135 respectively FHR; and 100%, 60%, 100%, 96.8% and 0.968 respectively FSpO2. CONCLUSIONS: 1. The examination of fetal blood oxygen saturation in the labor is a useful prognostic factor of the newborn outcome. 2. The best predictive value for intrapartum fetal asphyxia with metabolic acidosis was found when fetal pulse oximetry is added to cardiotocography.

[Use of oxi-cardiotocography in twin delivery].

The intrapartum management of multiple gestation continues to challenge the obstetrics profession. Electronic fetal heart rate monitoring and fetal pulse oximetry are used in clinical research to assess fetal well-being during labor. The objective of this study was to establish values of fetal arterial oxygen saturation (FSpO2) and some other parameters by dint of computerised analysis of cardiotocogram during twin delivery. 5 cases of vaginal twin deliveries as the Clinic of Perinatology of the Institute of Gynecology and Obstetrics Lodz Mecical University over the years 1988-1999 were reviewed. In four cases vertex-vertex twins were delivered vaginally, while in one case an assisted breech extraction was conducted on vertex-non vertex twins. The foetus was monitored continually with a Oxford S 8000 systems and pulse oximeter Nellcor N-400. the medium parameters of computerised analysis of CTG and FSpO2 during progressive stages of labour were shown. Twin delivery needs modern fetal monitoring tools to provide the obstetrician information on well-being of the foetus. It is possible to monitor fetal oxygen saturation and CTG parameters in both of the twins during labour The ability to measure fetal oxygen saturation especially during the second stage of twin labor adds critical information about fetal status and refines the interpretation of abnormal FHR patterns. Only after examining a large number of twin fetuses we can assess whether pulse oximetry in useful in management of labor.

[Fetal arterial oxygen saturation (FSpO2) during the second stage of labor after training for childbirth].

OBJECTIVE AND DESIGN: The aim of the research was to determine the effects of participating in training program for childbirth in Maternity School in Lódź on the state of the fetus. In the above research, the authors presented the foetal oxygen saturation (FSpO2) during the second stage of labour among the women participating in Maternity School as well as a control group. Our study analysed the neonatal outcome too (umbilical arterial blood pH and 5 min. Apgar score). MATERIAL AND METHODS: The test group consisted of eighty seven (87) healthy primigravidas of whom forty two (42) participated in classes in the Maternity School and forty fifth (45) made up the control group. Validity of the correlation was assessed by means of t-Student's table of N--2 degree of freedom. RESULTS: The medium parameters of FSpO2 values and duration of the second stage of labor in both groups were shown. Statistically significant differences between the groups were found in duration the second stage of labour--in Maternity School group being shorter. Statistically significant differences in FSpO2 values between groups were not observed.

[The effect of umbilical cord encirclement on fetal arterial oxygen saturation values].

AIM: Our purpose was to study fetal arterial oxygen saturation trends by continuous pulse oximetry during labour in subjects with and without umbilical cord encirclement. MATERIAL AND METHODS: The study was carried out in 46 pregnant women in the 38.9 +/- 1.4 weeks of pregnancy and the 15 of them with umbilical cord encirclement, established respectively after delivery. The fetus was monitored continuously with an Oxford S 8000 system and pulse oximeter Nellcor N-400. The medium parameters of FSpO2 values during progressive stages of labour in both groups were shown. The importance of the correlation was assessed using the t-Student's table of N--2 degree of freedom. RESULTS: In those two groups no significant difference between FspO2 value in first stage of labour was found. In second stage of labour our study showed tendency for higher oxygen saturation values in foetuses without umbilical cord compression.
