The advantage of the method is its minimal invasive character and the continuous monitoring of oxygen saturation. The pulse oximeter (N 400, Nellcor) had been blinded for the investigation following criteria met by FDA, so that the investigator could not read the saturation values. Preliminary results of more than 120 hours of monitoring intervals of 10 seconds show the following saturation values (median): 55% under normal CTG (10. perc. 36%, 90. perc. 73%), 42% during episodes of variable decelerations (10. perc. 22%, 90. perc. 63%), 53% during episodes of early decelerations (10. perc. 39%, 90. perc. 74%). Due to pathological fetal heart rate patterns 42 fetal blood analysis were performed. Because of these spectrophotometric saturation measurements (ABL 330, OSM 3, Radiometer) the deviation of the two methods could be calculated. The values of pulse oximetry were 5% higher than those of spectrophotometry. Correlation of both methods was r = 0.64.","PeriodicalId":23919,"journal":{"name":"Zeitschrift fur Geburtshilfe und Perinatologie","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1994-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19017808","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Measuring a hepatic vein directly before entering the inferior vena cava we found a characteristic blood flow pattern with a moderate foreward flow during systole and a small foreward flow during early diastole and a very small reverse flow because of atrial contraction during late diastole. We found changes in this flow pattern with reduction of the mean velocity in cases of high risk pregnancies with intrauterine growth retardation. Comparing normally developed fetuses with growth-retarded fetuses and vaginal delivery or caesarean sections without fetal distress with caesarean sections because of fetal distress we found significant differences with lower mean velocities in the precardiac veins of the latters. Comparing the precardiac venous flow velocities with the umbilical artery flow velocities and the fetal descending aortal flow velocities we found similar results of statistical values predicting growth retardation and caesarean section because of fetal distress. We concluded that venous Doppler flow velocity analysis is also able to predict perinatal risks like intrauterine growth retardation or caesarean section because of fetal distress as good as flow velocimetry of the umbilical artery or the fetal aorta; if it is impossible to demonstrate the fetal descending aorta or the vena cava inferior sonographically correctly the investigation of the hepatic vein may give you more reliable Doppler values for your clinical management.","PeriodicalId":23919,"journal":{"name":"Zeitschrift fur Geburtshilfe und Perinatologie","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1994-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19017859","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Adjuvant antibiotic treatment can improve the prolongative effects of tocolysis in patients with preterm labour. This study was conducted to evaluate the effectiveness of screening for infection and of antibiotic treatment in reducing postpartal infectious complications in patients with so called idiopathic preterm labour being treated with tocolysis intravenously. At the time of admission, we obtained cervical swabs of 138 patients for bacteriological investigation. 23 of the 37 patients with pathologic cervical colonisation were treated with antibiotics in addition to tocolysis. In women in preterm labour with pathologic cervical microbial colonisation, the frequencies of infectious complications in the puerperium were markedly increased compared to women without cervical colonisation. Adjuvant antibiotic therapy during pregnancy significantly reduced such complications. Additional antibiotic treatment of patients in idiopathic preterm labour with indicators of silent intrauterine infection seems beneficial not only for prolongation of gestation, but also for the reduction of postpartal infectious morbidity.","PeriodicalId":23919,"journal":{"name":"Zeitschrift fur Geburtshilfe und Perinatologie","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1994-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19017813","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"[Risk of neonatal acidosis and maternal respiration during labor].","authors":"V M Roemer, Y Vogel","doi":"","DOIUrl":"","url":null,"abstract":"Background: The reported incidence of neonatal acidosis varies++ significantly in different obstetrical departments. We wanted to investigate to which extend neonatal acidosis is depended on maternal respiration patterns during the third stage of labor.Methods: Maternal arterial blood gas analysis was performed in 101 term pregnancies. Fetal acid-base parameters from arterial and venous umbilical blood were assessed simultaneously. SPEARMAN rank correlation (rs) was used to investigate the statistical relationship of maternal and fetal blood gas parameters and pH-values. Moreover a computer model was developed to describe the influence of maternal respiration on neonatal acidotic risk figures.Results: A highly significant correlation was established between corresponding variables in maternal arterial blood and in venous umbilical blood (rs > or = 0.500, 2P < 0.001). These correlations were not as striking when comparing maternal parameters with corresponding variables in arterial umbilical blood. The partial oxygen pressure in arterial and venous umbilical blood did not show any correlation with the variables of the maternal acid-base status. In the computerized simulation model mild maternal hyperventilation during the third stage of labor decreased the risk of neonatal acidosis (pH, UA < 7.100%) by approximately 25% without evidence of lack of fetal oxygen supply.Conclusions: A mild maternal hyperventilation synchronized with uterine contractions during the third stage of labor in combination with rapid breathing when delivering the fetal head has a favourable influence on the neonatal acid-base balance. In this study there is no indication that such an obstetrical management results merely in a laboratory artifact, because according to our data there was indeed no indication of compromised fetal oxygen supply. Routine fetal blood sampling also from venous umbilical blood appears to be useful in differentiating between combined feto-maternal and isolated fetal variations in actual pH-values.","PeriodicalId":23919,"journal":{"name":"Zeitschrift fur Geburtshilfe und Perinatologie","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1994-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19158166","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore the purpose of our study was to investigate if quantitative determination of Il-1 beta, Il-6, Il-8 and TNF-a in amniotic fluid may be a practicable method to diagnose intraamniotic infection. Since invasive amniocentesis doesn't allow repeated cytokine detection, in case of preterm rupture of fetal membranes, amniotic fluid also was obtained by placing a sterile gauze and cotton pad into the women's vagina, absorbing draining amniotic fluid for cytokine detection. Our results clearly indicate that Il-1 beta and TNF-a are not detectable in normal pregnancy, while Il-6 and Il-8 are produced in low, but constant levels. In contrast, in amniotic fluid of patients with intraamniotic infection high amounts of Il-6 and Il-8 were found, while Il-1 beta and TNF-a bioactivity became measurable, indicating that biosynthesis was activated. These results demonstrate, that infection associated cytokines detectable in amniotic fluid are highly sensitive markers for intraamniotic infection. In case of preterm rupture of fetal membranes recovery of amniotic fluid from a vaginal pad allows monitoring of cytokine bioactivity in daily intervals to control success of antibiotic treatment.","PeriodicalId":23919,"journal":{"name":"Zeitschrift fur Geburtshilfe und Perinatologie","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1994-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19158164","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
