摘要:

In The Stockholm Pregnancy and Weight Development Study the relationships between birth weight and maternal initial body weight as well as weight increase during pregnancy were analysed in 2,295 subjects. As expected, the most important predictor of birth weight was total maternal weight increase, followed by initial maternal body weight. However, in women with an initial BMI value above 24 kg/m2, birth weight did not increase significantly in tact with maternal weight. The frequency of cesarean sections, 12% overall, was not significantly increased with maternal body weight. These data show that birth weight increases with maternal weight only up to the upper normal body weight.

摘要:

In 25 normally non‐pregnant women, 543 normally pregnent women and 75 pregnant women with diabetes mellitus or gestational diabetes mellitus, the relationship between the serum concentration of 1,5‐anhydro‐D‐glucitol (1‐deoxy‐glucose) and carbohydrate metabolism was studied. The concentration of 1,5‐anhydro‐D‐glucitol was estimated by means of gas‐liquid chromatography. In normally non‐pregnant women the concentration was found to be 18.6±5.2 mg/l (mean±SD). During the normal pregnancy, from 9 weeks of gestation, a steadily decreasing concentration was observed as the pregnancy progressed and the lowest value (10.214.6 mg/l) was found in the third trimester. After 5 days of puerperium the concentrations were found to be 10.8±3.7 mg/l. On the 30th day postpartum, the level was within the range for non‐pregnant subjects. The values in pregnant women with diabetes mellitus and gestational diabetes mellitus were mostly below 10 mg/l throughout the entire pregnant period. The 1, 5‐anhydro‐D‐glucitol concentration was not affected by meals or oral glucose loading. A concentration below 10 mg/l was found in 36% of the normally pregnant women, where oral glucose tolerance tests and measurement of glycohemoglobin were shown to be within the normal range. The present study suggests that a change of 1,5‐anhydro‐D‐glucitol level during pregnancy may reflect a mild alteration of carbohydrate metabolism that goes undetecte

摘要:

The effects of ritodrine infusion on fetal myocardial function and fetal hemodynamics were studied in 18 singleton, healthy, pregnant women with premature uterine contractions. Ritodrine was given intravenously for 2½h. In 10 cases both M‐mode echocardiographs of the fetal heart and measurements of the blood flow in the fetal descending thoracic aorta were made before and after the infusion. No changes took place in the functional parameters or ventricular size of the fetal heart during the infusion. Fetal heart rate increased significantly. In the aorta both the volumetric flow and time‐averaged systolic peak, mean and end‐diastolic velocities increased significantly, while there were no changes in waveform indices. In 8 other cases, blood velocity waveform indices were measured by color Doppler flow mapping from the fetal middle cerebral, renal and umbilical arteries. During the infusion the waveform indices decreased significantly in the middle cerebral and renal arteries. There was no change in the indices of the umbilical artery. Ritodrine did not cause any unfavorable changes in the fetal myocardial function or blood flow in the aorta and umbilical artery. The decreased waveform indices in fetal middle cerebral and renal arteries might indicate decreased vascular resitance in these v

摘要:

A method is described for recording blood flow velocity waveforms from fetal cerebral vessels during labor, using a 2 MHz pulsed Doppler ultrasound technique. Fifteen healthy women with uncomplicated pregnancies and labor without signs of fetal distress participated in the study. With membranes ruptured and cervix orifice open 4‐9 cm, the Doppler transducer was placed transvaginally on the fetal skull and the Doppler shift signals from the middle cerebral artery were located. The maximum velocity waveforms were recorded before, during and after uterine contractions and analysed off‐line for pulsatility index (PI). No differences in the PI were found with regard to the uterine contractions. The results suggest an unchanged peripheral resistance in the fetal cerebral vascular bed during the first stage of normal la

摘要:

A prospective randomized study was undertaken to evaluate the efficacy of a single dose of cefuroxime in alleviating infectious complications following non‐elective cesarean section. One hundred and two women were allocated to receive 750 mg of cefuroxime after cord clamping and 99 were allocated to a control group not receiving any antibiotic prophylaxis. The incidence of febrile morbidity was 2.0% in the cefuroxime group and 19.2% in the control group (p<0.001). The incidence of endometritis in the two groups was 1.0% and 6.1%, respectively, the incidence of fever of unknown origin was 1.0% and 9.1 %, respectively. Single‐dose cefuroxime prophylaxis significantly reduced the incidence of febrile morbidity in patients undergoing non‐elective cesarean section, without producing any side ef

摘要:

Results are presented from 128 oral glucose tolerance tests carried out 4 days (median) post partum in 129 women who gave birth to an infant with birthweight>4,500 g. Among these 129, only 1 overweight patient was found to be diabetic; testing revealed glucose intolerance in 7 patients, of whom 6 had returned to normal at re‐examination. These data are comparable to those found in a general Danish population screening. Oral glucose tolerance tests based upon blood glucose concentrations 2 h postprandially, performed in the puerperium, cannot be recommended as a screening procedure for diabetes mellitus. By re‐gressional analyses of data from 64 controls with normal‐weight offspring, including six factors customarily related to birth weight, the importance of each risk factor could be estimated. The following simple equation revealed a correlation coefficient of 0.69: Estimated birthweight = 122 x menostasia in weeks + 370 x average weight of siblings in kg + 43 x weight gain in pregnancy + 6 x maternal weight before pregnancy
