孕末期孕妇发热对胎儿的影响 总被引：1，自引：0，他引：1
目的:探讨孕末期孕妇发热对胎儿及新生儿的影响。方法:通过对105例孕末期发热的孕妇进行胎心监护,周期性胎心率的监测,羊水性状的观察,Manning评分,新生儿Apgar评分,初步分析孕妇发热对胎儿及新生儿的影响。结果:孕妇发热对胎儿会造成缺氧、胎儿宫内窘迫,表现为胎心率过速或过缓,LD(晚期减速)占37.10%,羊水Ⅱ°污染占86.67%,但不一定会造成新生儿窒息,表现为Apgar评分≤7分占25.71%。结论:孕妇发热明显地导致胎儿宫内缺氧及胎儿宫内窘迫。我们要积极预防治疗孕末期发热,并在治疗的同时选择合适的分娩方式结束妊娠。 相似文献

本文通过对3600例孕妇进行3898次胎心监护并在产后追踪观察,发现NST反应型,96％的新生儿1分Apgar评分≥8分,而CST阳性者,51％新生儿出现1分低Apgar评分．无论NST还是CST,评分越低,胎儿在宫内存在不利因素及新生儿出现低Apgar评分发生率愈高,四种常见的异常CTG图型为产程处理提供依据．可见通过监护可及早发现胎儿缺氧,从而积极采取相应措施,降低胎儿宫内窘迫和新生儿窒息的发生率,对指导临床工作、提高产科质量有重要意义． 相似文献

分娩期胎心正常应为120次/分～160次/分,且应当规律而有力,当胎心多于160次/分或少于120次/分,或者胎心快慢不均、强弱不等均属胎心异常。分娩期胎心异常是胎儿窘迫最早出现的主要征象,是新生儿发生窒息和死亡的主要原因。为此,为减少新生儿窒息率和死亡率的发生,必须加强产程监护,根据不同的病因来进行处理。现将分娩期胎心异常常见的病因及监护加以论述: 相似文献

The ontogeny of fetal autonomic, motoric, state, and interactive functioning was investigated longitudinally in a sample of 31 healthy fetuses from 20 weeks through term. Fetal heart rate and movement data were collected during 50 min of Doppler-based fetal monitoring at 6 gestational ages. Measures of fetal heart rate and variability, activity level and vigor, behavioral state, and reactivity were derived from these digitized data. Weighted least squares analyses were conducted to model the developmental patterns and to examine the role of maternal and fetal covariates. With advancing gestation, fetuses displayed slower heart rate, increased heart rate variability, reduced but more vigorous motor behavior, coalescence of heart rate and movement patterns into distinct behavioral states, and increasing cardiac responsivity to stimulation. Male fetuses were more active than female fetuses, and greater maternal stress appraisal was associated with reduced fetal heart rate variability. An apparent period of neurobehavioral transition exists between 28 and 32 weeks. Fetal research methods are evaluated. 相似文献

Fetal movement and habituation were examined in relation to behavior and development in early infancy. 39 fetuses were evaluated between 28 and 37 weeks gestation. A vibrating stimulus was repeatedly applied to the maternal abdomen until the fetus habituated (i.e., ceased moving in response). Fetal movements were observed on an ultrasound monitor by 2 observers who recorded their observations onto a strip chart. Using a median split, fetuses were placed into high- or low-movement groups and fast- or slow-habituating groups. The groups were compared after birth on the Brazelton Neonatal Behavior Assessment Scale and the Bayley Scales of Infant Development. Preliminary evidence is presented that fetal rate of habituation predicts some aspects of infant behavior and development. 相似文献

Objective: Polycystic ovary syndrome (PCOS), a common endocrine-metabolic dysfunction in reproductive-aged women, may be involved in compromised pregnancy and offspring outcomes. This study aimed to investigate whether maternal PCOS affects fetal growth, fetal development, and placental features. Methods: This retrospective case-control study included 60 pregnant women with PCOS (PCOS group) and 120 healthy pregnant women without PCOS (control group). Fetal magnetic resonance imaging (MRI) was performed followed by an ultrasound examination and indications for imaging, including known or suspected fetal pathology, history of fetal abnormality in previous pregnancy or in a family member, and concern for placenta accreta. Fetal MRI images were analyzed for head circumference (HC), abdomen circumference (AC), lung-to-liver signal intensity ratio (LLSIR, a prenatal marker of fetal lung maturity), lengths of liver and kidney diameters in fetuses, and placental relative signal intensity on T2-weighted single-shot fast spin echo (SSFSE) imaging (rSISSFSE), and placental relative apparent diffusion coefficient value (rADC). Data on height and weight of offspring were collected through telephone follow-up. Results: Compared to the control group, the PCOS group showed the following characteristics: (1) smaller biparietal diameter and femur length in fetuses (P=0.026 and P=0.005, respectively), (2) smaller HC in fetuses (evident after 32 weeks; P=0.044), (3) lower LLSIR and smaller dorsoventral length of liver in fetuses (evident before 32 weeks; P=0.005 and P=0.019, respectively), and (4) smaller placental thickness (evident before 32 weeks; P=0.017). No significant differences in placental rSISSFSE or rADC were observed between the groups (all P>0.05). No significant differences in height and weight of offspring during childhood existed between the groups (all P>0.05). Conclusions: There exist alterations of fetal growth, fetal development, and placental features from women with PCOS. 相似文献

Stability in cardiac indicators before birth and their utility in predicting variation in postnatal development were examined. Fetal heart rate and variability were measured longitudinally from 20 through 38 weeks gestation (n = 137) and again at age 2 (n = 79). Significant within-individual stability during the prenatal period and into childhood was demonstrated. Fetal heart rate variability at or after 28 weeks gestation and steeper developmental trajectories were significantly associated with mental and psychomotor development at 2 years (n = 82) and language ability at 2.5 years (n = 61). These data suggest that the foundations of individual differences in autonomic control originate during gestation and the developmental momentum of the fetal period continues after birth. 相似文献

INTRODUCTION Congenital heart disease (CHD) is the most common congenital disorder resulting in significant prenatal and postnatal morbidity and mortality (Gil- lum, 1994; Gembruch, 1997) and is believed to be a multifactorial disorder arising from the combined effect of genetic predisposition and environmental factors. Prenatal diagnosis of CHD is very important for both fetal prognosis and decreasing economic burden of family and society. It was demonstratedt t - l t recently that fe… 相似文献

Fetal neurobehavioral development was modeled longitudinally using data collected at weekly intervals from 24 to 38 weeks gestation in a sample of 112 healthy pregnancies. Predictive associations between 3 measures of fetal neurobehavioral functioning and their developmental trajectories to neurological maturation in the first weeks after birth were examined. Prenatal measures included fetal heart rate (FHR) variability, fetal movement, and coupling between fetal motor activity and heart rate patterning; neonatal outcomes include a standard neurologic examination ( n = 97) and brainstem auditory evoked potential (BAEP; n = 47). Optimality in newborn motor activity and reflexes was predicted by fetal motor activity, FHR variability, and somatic–cardiac coupling predicted BAEP parameters. Maternal pregnancy-specific psychological stress was associated with accelerated neurologic maturation. 相似文献
