The newborns of the study group showed all different kinds of cord entanglements (CE, N = 3430); neonates without CE were used as controls (N = 7144).

The numerical value of AVD-pH seems to be a function of the clinical condition of the newborn: maximum value (mean = 0.113) was reached at Apgar 7; increasing neonatal distress was accompanied by low AVD-pH-values. This phenomenon was due to a decrease of actual pH in UA-blood and an increase in UV-blood; the latter was statistically feasible (P = 0.025) only in neonates with Apgar 8. AVD-pH-values of neonates above the 75. weight-centile showed a different reaction-pattern in individual Apgar-scores when compared with infants below the 25. centile: They remain constant or are slightly increased. We concluded, that blood-flow reduction in the umbilical vessels leads to a flow-dependent improvement of fetal pCO2-excretion at the placental level, which counteracts the developing metabolic fetal acidosis.(ABSTRACT TRUNCATED AT 250 WORDS)</p>","PeriodicalId":23919,"journal":{"name":"Zeitschrift fur Geburtshilfe und Perinatologie","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1993-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"19467265","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}

For that reason the electron microscope method with an optically higher resolution was chosen for this thesis. In total, 20 umbilical cords were recovered, and in each case one of the two umbilical cord arteries was kept in a condition of non-contraction by means of perfusion fixation immediately after the omphalotomy. After the necessary preparation longitudinal, diagonal and cross-sections of both non-contracted and fully contracted umbilical arteries as well as of the folds of Hoboken, which occur in the arteries postnatally, were investigated by the scanning electron microscope. During this examination the following findings were made: The media in the wide umbilical cord artery consists of two layers. The outer layer accounts for some three quarters of the wall and is composed of lamellae of parallel muscle fibres which surround the vessel alternatively in gently rising and falling thread-like turns. The inner layer accounts for the remaining quarter and also consists of lamellae the thread-like turns of which, however, run at a much higher pitch. Exactly subendothelial, a very thin layer of irregularly arranged fibres with longitudinal main direction can be clearly identified. The folds of Hoboken are caused by local media contraction in the course of which the outer media restructures itself, thus being the main carrier of the fold.(ABSTRACT TRUNCATED AT 250 WORDS)</p>","PeriodicalId":23919,"journal":{"name":"Zeitschrift fur Geburtshilfe und Perinatologie","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1992-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"12464279","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}
