摘要:

Abstract.During the past four years, an attempt has been made in MalmO to reduce the frequency of preterm termination of twin pregnancies. For this purpose, the entire pregnant population of this medium‐sized city was subjected to general ultrasonic screening in the second trimester. This detected 88 per cent of the twin pregnancies. The screening had a methodological error of 2 per cent. Eightysix of the women with twin pregnancy were subjected to bedrest in hospital for more than two weeks in the second half of gestation. The incidences of twins born with birth weight below 1500 g and of twins light‐for‐gestational‐age were reduced compared with those a decade earlier. Also the group of twins born before the 37th week decreased, and the perinatal mortality rate fell to the same level as in singleton pregnancies. Early detection of twin pregnancies followed by rest for the pregnant women seems to contribute to an improved outcome of these ges

摘要:

Abstract.The Hb level during pregnancy was followed in 113 non‐anaemic women with uncomplicated pregnancy and birth weight of the baby above the 2.5th percentile. There was an inverse correlation close to statistical significance between the birth weight of the baby and the lowest Hb level reached during pregnancy as well as the Hb level in late pregnancy (38th week). A group of seven non‐anaemic women with birth weight of the baby below the 2.5th percentile had a significantly higher (p<0.001) Hb level in late pregnancy than the normal group. Four of these cases had a statistically significant higher Hb level already in the second trimester. Trends in the reproductive history, complaints in the present pregnancy as well as results of hormone assays and the condition of the baby indicated that the seven cases represented a pathological group with fetal growth retardation. None of the women in the two groups were treated with diuretics. All had iron supplementation in high do

摘要:

Abstract.Nausea and vomiting during pregnancy (NVP) has been associated with favorable pregnancy outcome, though little is known about factors influencing its occurrence. In this study, information on NVP in 210 patients at a west coast health maintenance organization was obtained. Smoking and alcohol consumption before and during pregnancy were also estimated in two personal interviews during gestation. In all, 72% of the subjects had NVP in the first 4 months of pregnancy. Smokers had significantly less NVP than non‐smokers (52% vs. 79%). Furthermore, NVP in smokers was negatively associated with alcohol consumption before and during pregnancy, with the stronger relation being for alcohol reported in the 6 months before pregnancy; only 46% of smokers drinking more than 1 fl. oz. of absolute alcohol daily in this period reported NVP, while 68% of smokers drinking less had NVP. For non‐smokers, there was no relation between alcohol use in any period and NVP. The risk of NVP associated with pre‐pregnancy drinking was not related to any change in alcohol consumption after conception. These results suggest an interaction between NVP, smoking, and reported alcohol consumption. The association of favorable pregnancy outcome with NVP may be in part a reflection of moderation in maternal alcohol and tobacc

摘要:

Abstract.In normal, primigravidae red cell 2.3‐diphosphoglycerate (2.3‐DPG) concentration was found to be increased significantly from the third month of pregnancy. The 2.3‐DPG concentration remained elevated throughout pregnancy. Increase in the 2.3‐DPG concentration leads to a decrease in the oxygen affinity of the maternal red cells. The combination of low pC02and low oxygen affinity of the maternal blood facilitates the transport of oxygen as well as that of carbon dioxide across the placenta. The weight of the delivered children was not significantly correlated to the 2.3‐DPG changes, and no significant variation of the measured variables could be detected in 9 women with abnormal pr

摘要:

Abstract.The use of oral prostaglandin E2(PGE2) tablets is an effective and safe adjunct to low amniotomy for the induction of labour at term. Routine use of this regimen and the use of oral PGE2tablets for augmentation of spontaneous labour has shown that the method is very effective in multiparous patients, but much less so in primiparous patients. Success or failure could not be predicted by the pre‐induction Bishop score. The incidence of gastro‐intestinal side effects is dose dependent, but is low in multiparous patie

摘要:

Abstract.The concentrations of plasmatic fibrinogen and its degradation products (FDPs), and the paracoagulation test using serial dilution of protamine sulphate (SDPS) were determined during the third trimester of pregnancy, labor, and puerperium. Significant increases in the concentrations of fibrinogen and FDPs were observed throughout the process of pregnancy and birth, combined with both positive and negative SDPS tests. We suggest that these findings do not indicate a process of physiological DIC.

摘要:

Abstract.A series of 193 cases of abruptio placentae in a hospital population of 35 217 is described. This is an incidence of 0.55%. In the series both age and parity, but not pre‐eclarapsia or anaemia, are significant associated factors. The recurrence rate of abruptio placentae was 5.6%. There were no maternal deaths and the perinatal mortality was 35%. Epidural analgesia does not abolish the pain of the abruptio placentae in spite of abolishing the pain of labou

摘要:

Abstract.Abruptio placentae was a common cause of perinatal death in Addis Ababa, Ethiopia in 1974–1975 with a frequency of 5.5/1000 births. The disorder had its peak frequency at term. No abnormalities were found in the placentas to explain the placental abruptions but there were other clues to their genesis. There was a strong association of the fatal abruptions with severe poverty in the mothers. These poor mothers were both undernourished and malnourished during pregnancy. Their fetuses and neonates who died had multiple evidences of undernutrition including a relative undergrowth of adrenals, spleens and livers and a relative acceleration of lung maturation. These findings support observations in more prosperous nations that poor nutrition of the gravida may have an important role in the genesis of abruptio placenta

摘要:

Abstract.30 parturient women were randomized into a group receiving paracervical block (PCB) and a control group. The infants were tested by a neurobehavioral examination immediately after birth, after 3 hours and 3 days. The examiner was unaware of the obstetrical management of the patients. No clinically significant differences could be detected between the two groups. Arterial and venous pO2, pCO2and pH from the umbilical cord showed no differences between the groups.
