The active sympathomimetic hormone from the ADRENAL MEDULLA. It stimulates both the alpha- and beta- adrenergic systems, causes systemic VASOCONSTRICTION and gastrointestinal relaxation, stimulates the HEART, and dilates BRONCHI and cerebral vessels. It is used in ASTHMA and CARDIAC FAILURE and to delay absorption of local ANESTHETICS.
Peripheral Nervous System Diseases
A 51-amino acid pancreatic hormone that plays a major role in the regulation of glucose metabolism, directly by suppressing endogenous glucose production (GLYCOGENOLYSIS; GLUCONEOGENESIS) and indirectly by suppressing GLUCAGON secretion and LIPOLYSIS. Native insulin is a globular protein comprised of a zinc-coordinated hexamer. Each insulin monomer containing two chains, A (21 residues) and B (30 residues), linked by two disulfide bonds. Insulin is used as a drug to control insulin-dependent diabetes mellitus (DIABETES MELLITUS, TYPE 1).

Nitric Oxide Synthase Type I
A disorder characterized by a reduction of oxygen in the blood combined with reduced blood flow (ISCHEMIA) to the brain from a localized obstruction of a cerebral artery or from systemic hypoperfusion. Prolonged hypoxia-ischemia is associated with ISCHEMIC ATTACK, TRANSIENT; BRAIN INFARCTION; BRAIN EDEMA; COMA; and other conditions.
Nitric Oxide Synthase
A heterogeneous group of nonprogressive motor disorders caused by chronic brain injuries that originate in the prenatal period, perinatal period, or first few years of life. The four major subtypes are spastic, athetoid, ataxic, and mixed cerebral palsy, with spastic forms being the most common. The motor disorder may range from difficulties with fine motor control to severe spasticity (see MUSCLE SPASTICITY) in all limbs. Spastic diplegia (Little disease) is the most common subtype, and is characterized by spasticity that is more prominent in the legs than in the arms. Pathologically, this condition may be associated with LEUKOMALACIA, PERIVENTRICULAR. (From Dev Med Child Neurol 1998 Aug;40(8):520-7)
NG-Nitroarginine Methyl Ester
A free radical gas produced endogenously by a variety of mammalian cells, synthesized from ARGININE by NITRIC OXIDE SYNTHASE. Nitric oxide is one of the ENDOTHELIUM-DEPENDENT RELAXING FACTORS released by the vascular endothelium and mediates VASODILATION. It also inhibits platelet aggregation, induces disaggregation of aggregated platelets, and inhibits platelet adhesion to the vascular endothelium. Nitric oxide activates cytosolic GUANYLATE CYCLASE and thus elevates intracellular levels of CYCLIC GMP.
Cells lining the outside of the BLASTOCYST. After binding to the ENDOMETRIUM, trophoblasts develop into two distinct layers, an inner layer of mononuclear cytotrophoblasts and an outer layer of continuous multinuclear cytoplasm, the syncytiotrophoblasts, which form the early fetal-maternal interface (PLACENTA).
Class I human histocompatibility (HLA) surface antigens encoded by alleles on locus B of the HLA complex. The HLA-G antigens are considered non-classical class I antigens due to their distinct tissue distribution which differs from HLA-A; HLA-B; and HLA-C antigens. Note that several isoforms of HLA-G antigens result from alternative splicing of messenger RNAs produced from the HLA-G*01 allele.
The development of the PLACENTA, a highly vascularized mammalian fetal-maternal organ and major site of transport of oxygen, nutrients, and fetal waste products between mother and FETUS. The process begins at FERTILIZATION, through the development of CYTOTROPHOBLASTS and SYNCYTIOTROPHOBLASTS, the formation of CHORIONIC VILLI, to the progressive increase in BLOOD VESSELS to support the growing fetus.
A highly vascularized mammalian fetal-maternal organ and major site of transport of oxygen, nutrients, and fetal waste products. It includes a fetal portion (CHORIONIC VILLI) derived from TROPHOBLASTS and a maternal portion (DECIDUA) derived from the uterine ENDOMETRIUM. The placenta produces an array of steroid, protein and peptide hormones (PLACENTAL HORMONES).
The hormone-responsive glandular layer of ENDOMETRIUM that sloughs off at each menstrual flow (decidua menstrualis) or at the termination of pregnancy. During pregnancy, the thickest part of the decidua forms the maternal portion of the PLACENTA, thus named decidua placentalis. The thin portion of the decidua covering the rest of the embryo is the decidua capsularis.

Sleep Apnea, Obstructive
A disorder characterized by recurrent apneas during sleep despite persistent respiratory efforts. It is due to upper airway obstruction. The respiratory pauses may induce HYPERCAPNIA or HYPOXIA. Cardiac arrhythmias and elevation of systemic and pulmonary arterial pressures may occur. Frequent partial arousals occur throughout sleep, resulting in relative SLEEP DEPRIVATION and daytime tiredness. Associated conditions include OBESITY; ACROMEGALY; MYXEDEMA; micrognathia; MYOTONIC DYSTROPHY; adenotonsilar dystrophy; and NEUROMUSCULAR DISEASES. (From Adams et al., Principles of Neurology, 6th ed, p395)
A state arrived at through prolonged and strong contraction of a muscle. Studies in athletes during prolonged submaximal exercise have shown that muscle fatigue increases in almost direct proportion to the rate of muscle glycogen depletion. Muscle fatigue in short-term maximal exercise is associated with oxygen lack and an increased level of blood and muscle lactic acid, and an accompanying increase in hydrogen-ion concentration in the exercised muscle.

The cardiovascular and cerebrovascular responses of the immature fetal sheep to acute umbilical cord occlusion. (1/214)1. In premature fetal sheep (89-93 days gestation) we examined the fetal response to asphyxia induced by 30 min of complete umbilical cord occlusion. Fetuses were also studied during the first 3 days after asphyxia. We measured heart rate, blood pressure, carotid and femoral blood flows, vascular resistance, electroencephalographic activity and cerebral changes in haemoglobin concentration by near infrared spectroscopy (NIRS). 2. Fetuses tolerated 30 min of asphyxia and the cardiovascular response was characterized by three phases: initial redistribution of blood flow away from the periphery to maintain vital organ function, partial failure of this redistribution and near terminal cardiovascular collapse, with profound hypotension and cerebral and peripheral hypoperfusion. 3. Post-asphyxia carotid blood flow and NIRS data demonstrated that between 3-5 h there was a significant secondary reduction in cerebral blood flow, blood volume and oxygenation despite normal perfusion pressure and heart rate. There was also a secondary fall in femoral blood flow which persisted throughout recovery. 4. These data demonstrate that the immature fetus can survive a prolonged period of asphyxia, but paradoxically the capacity to survive exposes the fetus to profound hypotension and hypoperfusion. A secondary period of significant cerebral hypoperfusion and reduced oxygen delivery also occurred post-asphyxia. These cardiovascular and cerebrovascular responses may contribute to the patterns of cerebral injury seen in the human preterm fetus. (+info)
Visual function in term infants with hypoxic-ischaemic insults: correlation with neurodevelopment at 2 years of age. (2/214)AIMS: To determine if there is any association between the findings of visual assessment performed at the age of 5 months and neurodevelopmental outcome at the age of 2 years in children who have sustained hypoxic-ischaemic insults. METHODS: Twenty nine term infants with hypoxic-ischaemic encephalopathy and/or brain lesions on neonatal magnetic resonance imaging (MRI) were prospectively evaluated. At 5 months of age all the infants had their visual function assessed using the Atkinson Battery of Child Development for Examining Functional Vision, which includes the assessments of optokinetic nystagmus (OKN), acuity, visual fields, fixation shift and phase and orientation reversal visual evoked potentials. At 2 years of age the children had a structured neurological evaluation and a Griffiths developmental assessment. RESULTS: There was good correlation between the extent of the early detected visual impairment and both neuromotor and global development. Children with more than three out of five abnormal visual tests at 5 months of age tended to have abnormal neurological examination results and abnormal developmental quotients. Children with three or fewer abnormalities tended to have developmental quotients in the normal range; the level of their performance, however, was still related to the number of visual tests passed. CONCLUSIONS: Individual visual tests can provide important prognostic information. While abnormal OKN and acuity were always associated with abnormal outcome, normal results on visual evoked potentials and fixation shift tended to be associated with normal outcome. (+info)
Does endothelin-1 reduce superior mesenteric artery blood flow velocity in preterm neonates? (3/214)AIM: To compare plasma endothelin-1 (ET-1) concentrations in preterm neonates from pre-eclamptic and normal mothers; and to evaluate whether ET-1 has a role in altered arterial blood flow velocity. METHODS: Umbilical arterial blood and neonatal arterial blood were sampled on days 1 and 3 for gas analysis and measurement of plasma ET-1. Doppler ultrasonography of the middle cerebral, renal, and superior mesenteric arteries (SMA) was performed. RESULTS: Neonates in the pre-eclampsia (n = 18) and control (n = 18) groups had mean (SD) gestational ages of 31.1 (2.5) weeks and 30.4 (2.1) weeks; their birth-weights were 1432 (SD 676) g and 1692 (SD 500) g, respectively. In the pre-eclampsia group mean umbilical arterial PO2 was lower--1.88 (0.75) kPa compared with 3.27 (1.41) kPa (p < 0.01)--and mean plasma ET-1 concentration was higher in the umbilical artery--40.6 (SD 15.0) compared with 30.5 (SD 13.8) pg/ml (p = 0.04) and day 1 blood--54.9 (35.0) pg/ml compared with 33.6 (14.6) pg/ml (p = 0.03). Middle cerebral artery peak systolic velocity was higher and SMA time averaged, peak systolic, and mean peak velocities were lower in the pre-eclampsia group. SMA time averaged velocity was inversely related to plasma ET-1 concentration. CONCLUSION: The association between increased production of ET-1 and reduction in SMA time averaged velocity suggests a possible mechanism for hypoperfusion of the intestinal wall in neonates.

Chronic hypoxemia: effects on developing nitrergic and dopaminergic amacrine cells. (4/214)PURPOSE: Very low birth weight and growth-restricted children have visual impairments including reduced contrast sensitivity, a parameter mediated in part by dopaminergic amacrine cells. The origin of these deficits is uncertain. In experimental fetal growth restriction, induced by placental insufficiency, the morphology and number of dopaminergic amacrine cells as identified by tyrosine hydroxylase staining were examined. In addition, the subclass of nitrergic amacrine cells was examined because nitric oxide released from nitric oxide synthase- containing neurons is proposed as a mediator of neurotoxicity and might contribute to the injury of dopaminergic amacrine cells in this situation. METHODS: Fetal sheep were subjected to 20 or 30 days of placental embolization leading to fetal hypoxemia, hypoglycemia, and growth restriction during the last third of gestation (term, approximately 147 days). Retinal tissue was prepared as wholemounts or cryostat sections and analyzed for retinal area, total number, density, somal size and cell process length of amacrine cells immunoreactive for tyrosine hydroxylase or nitric oxide synthase, and widths of retinal layers. Retinas from fetal sheep at 72, 96, 113, and 140 days' gestation and adults were collected for an ontogenetic study of tyrosine hydroxylase-immunoreactive neurons. RESULTS: In growth-restricted fetuses, the number of tyrosine hydroxylase-immunoreactive neurons and the total length of stained processes per cell were significantly reduced compared to control fetuses. The total number of neuronal nitric oxide synthase- containing neurons was not different between growth-restricted and control fetuses. The thickness of the inner retinal layers was reduced in hypoxemia. CONCLUSIONS: There is damage to tyrosine hydroxylase-immunoreactive amacrine cells during fetal chronic placental insufficiency. This damage might be involved in the altered retinal dopaminergic system observed in very low birth weight infants, some of whom are growth-restricted. Furthermore, a differential susceptibility of tyrosine hydroxylase-immunoreactive and neuronal nitric oxide synthase-containing amacrine cells to hypoxemic injury has been demonstrated. These observations add to the current hypothesis that neuronal nitric oxide synthase- containing neurons are resistant to hypoxemic injury and may be involved in mediating some of the neuronal damage that results from hypoxemic insults.

Metabolic and cardiorespiratory responses to hypoxia in fetal sheep: adenosine receptor blockade. (5/214)8-Phenyltheophylline (PT), a potent and specific inhibitor of adenosine receptors, was infused intra-arterially into unanesthetized fetal sheep to determine the role of adenosine in hypoxic inhibition of fetal breathing. PT in normoxic fetuses increased heart rate and the incidence of low-voltage electrocortical activity, rapid eye movements (REM), and breathing. Mean breath amplitude increased by 44%. Hypoxia (preductal arterial PO2 = 14 Torr) induced a metabolic acidemia, a transient bradycardia, and hypertension while virtually eliminating REM and breathing. PT administration during hypoxia enhanced the metabolic acidemia, blocked the bradycardia and hypertension, increased the incidence of REM and breathing, and elevated mean breath amplitude. The results indicate that 1) adenosine is involved in fetal glycolytic and cardiovascular responses to hypoxia, 2) activation of central adenosine receptors mediates about one-half the inhibitory effects of hypoxia on REM and breathing, and 3) the depression of breathing may critically depend on a hypoxia-induced reduction in phasic REM sleep.

Measurement of the urinary lactate:creatinine ratio for the early identification of newborn infants at risk for hypoxic-ischemic encephalopathy. (6/214)BACKGROUND: Newborn infants with perinatal asphyxia are prone to the development of hypoxic-ischemic encephalopathy. There are no reliable methods for identifying infants at risk for this disorder. METHODS: We measured the ratio of lactate to creatinine in urine by proton nuclear magnetic resonance spectroscopy within 6 hours and again 48 to 72 hours after birth in 58 normal infants and 40 infants with asphyxia. The results were correlated with the subsequent presence or absence of hypoxic-ischemic encephalopathy. RESULTS: Hypoxic-ischemic encephalopathy did not develop in any of the normal newborns but did develop in 16 of the 40 newborns with asphyxia. Within six hours after birth, the mean (+/-SD) ratio of urinary lactate to creatinine was 16.75+/-27.38 in the infants who subsequently had hypoxic-ischemic encephalopathy, as compared with 0.09+/-0.02 in the normal infants (P<0.001) and 0.19+/-0.12 in the infants with asphyxia in whom hypoxic-ischemic encephalopathy did not develop (P<0.001). A ratio of 0.64 or higher within six hours after birth had a sensitivity of 94 percent and a specificity of 100 percent for predicting the development of hypoxic-ischemic encephalopathy. The sensitivity and specificity of measurements obtained 48 to 72 hours after birth were much lower. The mean ratio of urinary lactate to creatinine was significantly higher in the infants who had adverse outcomes at one year (25.36+/-32.02) than in the infants with favorable outcomes (0.63+/-1.50) (P<0.001). CONCLUSIONS: Measurement of the urinary lactate: creatinine ratio soon after birth may help identify infants at high risk for hypoxic-ischemic encephalopathy. (+info)
Hemodynamic and metabolic responses to moderate asphyxia in brain and skeletal muscle of late-gestation fetal sheep. (7/214)The purpose of this study was to investigate metabolic and hemodynamic responses in two fetal tissues, hindlimb muscle and brain, to an episode of acute moderate asphyxia. Near-infrared spectroscopy was used to measure changes in total hemoglobin concentration ([tHb]) and the redox state of cytochrome oxidase (COX) simultaneously in the brain and hindlimb of near-term unanesthetized fetal sheep in utero. Oxygen delivery (DO(2)) to, and consumption (VO(2)) by, each tissue was derived from the arteriovenous difference in oxygen content and blood flow, measured by implanted flow probes. One hour of moderate asphyxia (n = 11), caused by occlusion of the maternal common internal iliac artery, led to a significant fall in DO(2) to both tissues and to a significant drop in VO(2) by the head. This was associated with an initial fall in redox state COX in the leg but an increase in the brain. [tHb], and therefore blood volume, fell in the leg and increased in the brain. These data suggest the presence of a fetal metabolic response to hypoxia, which, in the brain, occurs rapidly and could be neuroprotective. (+info)
Fetal complications of obstetric cholestasis. (8/214)Among 56 pregnancies complicated by obstetric cholestasis five intrauterine deaths and one neonatal death occurred between 33 and 39 weeks, and a further six infants required urgent delivery for intrapartum asphyxia. Eighteen spontaneous premature deliveries occurred. Five mothers required specific treatment for unexplained postpartum haemorrhage. Cholestasis of pregnancy is therefore not a condition benign to the fetus, and it may contribute to increased maternal morbidity. (+info)
What is intrauterine hypoxia of the fetus | Tip10
Called Hypoxia of anoxia. If the fetus is in the womb for some reason cant get oxygen in sufficient quantities, doctors to talk about fetal hypoxia. The causes of intrauterine fetal hypoxia is diverse. These are common in pregnant women with asthma, chronic bronchitis, heart disease, diabetes, hypertension, and smokers. Hypoxia may occur due to severe toxemia, fetoplacental insufficiency, iron deficiency anemia, intrauterine infection of the fetus with herpes, toxoplasmosis, mycoplasmosis. Hypoxia and hemolytic disease of the fetus occurring as a result of rhesus-conflict. This happens in multiple pregnancies and polyhydramnios.It is important to detect intrauterine hypoxia of the fetus. To do this, a pregnant woman should regularly visit the gynecologist and to pass all the examinations, which she appoints.Distinguish between chronic and acute hypoxia of the fetus. In the second case, the fetus may die in a few minutes. This occurs when obvity umbilical cord, uterine rupture, placental abruption. In
Sex-Specific Effects of Nanoparticle-Encapsulated MitoQ (nMitoQ) Delivery to the Placenta in a Rat Model of Fetal Hypoxia -...
Pregnancy complications associated with chronic fetal hypoxia have been linked to the development of adult cardiovascular disease in the offspring. Prenatal hypoxia has been shown to increase placental oxidative stress and impair placental function in a sex-specific manner, thereby affecting fetal development. As oxidative stress is central to placental dysfunction, we developed a placenta-targeted treatment strategy using the antioxidant MitoQ encapsulated into nanoparticles (nMitoQ) to reduce placental oxidative/nitrosative stress and improve placental function without direct drug exposure to the fetus in order to avoid off-target effects during development. We hypothesized that, in a rat model of prenatal hypoxia, nMitoQ prevents hypoxia-induced placental oxidative/nitrosative stress, promotes angiogenesis, improves placental morphology, and ultimately improves fetal oxygenation. Additionally, we assessed whether there were sex differences in the effectiveness of nMitoQ treatment. Pregnant ...
BIOMARKERS OF INTRAUTERINE HYPOXIA AND PERINATAL ASPHYXIA, AND GESTATIONAL AGE AS PREDICTORS OF NEONATAL OUTCOME
Fetal life occurs in a relatively hypoxic environment. During normal pregnancy, several compensatory mechanisms secure fetal oxygenation and wellbeing. In complicated pregnancies, however, intrauterine hypoxia predisposes the fetus to growth restriction, stillbirth, neurodevelopmental sequelae such as cognitive dysfunction and cerebral palsy (CP), and adverse long-term health impacts. Impairment of respiratory gas exchange-during either pregnancy or delivery-leads to tissue hypoxia, and, if prolonged, to metabolic acidosis and asphyxia. Worldwide, such asphyxia, diagnosed at birth, annually accounts for a million neonatal deaths. Furthermore, neonatal hypoxic ischemic encephalopathy (HIE) originating from perinatal asphyxia may lead to a variety of neurodevelopmental impairments. Therapeutic neuroprotective interventions such as hypothermia have significantly improved the prognosis of severe neonatal encephalopathy. Increased risk for intrauterine fetal hypoxia and perinatal asphyxia occur in ...
Antenatal allopurinol for reduction of birth asphyxia induced brain damage (ALLO-Trial); a randomized double blind placebo...
Hypoxic-ischaemic encephalopathy is associated with development of cerebral palsy and cognitive disability later in life and is therefore one of the fundamental problems in perinatal medicine. The xanthine-oxidase inhibitor allopurinol reduces the formation of free radicals, thereby limiting the amount of hypoxia-reperfusion damage. In case of suspected intra-uterine hypoxia, both animal and human studies suggest that maternal administration of allopurinol immediately prior to delivery reduces hypoxic-ischaemic encephalopathy. The proposed trial is a randomized double blind placebo controlled multicenter study in pregnant women at term in whom the foetus is suspected of intra-uterine hypoxia. Allopurinol 500 mg IV or placebo will be administered antenatally to the pregnant woman when foetal hypoxia is suspected. Foetal distress is being diagnosed by the clinician as an abnormal or non-reassuring foetal heart rate trace, preferably accompanied by either significant ST-wave abnormalities (as detected by

Since preeclampsia was first described by Hippocrates in 400 BC, the theory of its causation has shifted from toxins to a current theory that incorporates both vascular and immunological causation. Poor placentation whether it is genetically predisposed or due to low expression of defective HLA-G on fetal trophoblasts is believed to be the initial insult. Oxidative stress from placental ischemia/hypoxia leads to an overload of trophoblast debris by stimulating apoptosis or necrosis. Partial failure of the maternal immune system to tolerate the paternal alloantigens activates maternal immune cells to secrete cytokines whose pleiotropic functions lead to dysfunction of the maternal vascular and placental endothelium, blood coagulation, and fibrinolytic system ...
Nova Biomedical : World Leader in Biosensor Technology
Foetal lactate estimation has long been recognised as an alternative method of establishing the presence of foetal metabolic acidaemia. With recent updates to the NICE clinical guideline 190 (for intrapartum care for healthy women and babies), more obstetricians are using lactate foetal blood sampling (FBS) to determine intrapartum foetal hypoxia and acidosis. Lactate testing can be revolutionary in cases where pH FBS testing is inappropriate or the sample is inadequate or of a poor quality. Although routinely used in Sweden, France and Australia, UK obstetricians have been hesitant to adopt lactate point-of-care testing (POCT) without evidence-based practice. This webinar will cover the benefits of lactate POCT using FBS, how lactate FBS compares to pH in identifying intrapartum foetal distress, and an overview of a NHS trust study to determine the impact of lactate POCT on the detection of foetal hypoxia and acidosis during labour. ...

Here, we show that male, but not female, offspring that were exposed to prenatal hypoxia develop altered circulatory and vascular function that implicates the ET-1 system. To summarize, we found the following: (1) IUGR males had increased conversion of bET-1 to active ET-1 compared with controls, and this effect was partially normalized with L-NAME treatment; (2) no differences in bET-1 conversion to active ET-1 were observed between aged control and IUGR female offspring; (3) no differences in ET-1 interaction with its receptors were observed between control and IUGR offspring in either male or female offspring; (4) male IUGR offspring were hypertensive, and this increase in BP was partially mitigated by treatment with the dual ETA/B receptor antagonist tezosentan; (5) female IUGR offspring were not hypertensive compared with control offspring, and tezosentan treatment had little effect in either female treatment group. These results suggest that the ET-1 system, and possibly the conversion of ...

Abstract 12791: Heart Rate at One Minute Impact Neonatal Resuscitation & Clinical Outcomes in Infants | Circulation
Introduction: Fetal hypoxia from intrapartum events can lead to absent heart rate (HR) or bradycardia (BC) at birth requiring neonatal resuscitation. Neonatal resuscitation guidelines do not differentiate infants with BC (HR,100/min) from absent HR at birth;. Hypothesis: As HR is the primary determinant of resuscitation, we hypothesize that infants with no HR at 1min [determined by Apgar score (AS) of 0 @ 1min] would require more extensive resuscitation with worse clinical outcomes compared to infants with BC at 1min (determined by AS=1 @ 1 min).. Methods: A retrospective analysis was done on infants born from 1/1/00 - 12/31/15 with AS of 0 (ASZ grp) or AS of 1 (ASN grp) at 1min. Patient demographics, resuscitation characteristics & clinical outcomes were analyzed in both the groups. Descriptive statistics & logistic procedure was performed (SAS System, Cary, NC).. Results: Table.1 summarizes the resuscitation characteristics analyzed. AS were different between the groups over time (Fig.1). ...

TY - JOUR. T1 - Ultrasonographic assessment of growth and estimation of birthweight in late gestation fetal sheep. AU - Carr, David J. AU - Aitken, Raymond P. AU - Milne, John S. AU - David, Anna L. AU - Wallace, Jacqueline M. PY - 2011/10. Y1 - 2011/10. N2 - Our aim was to identify which ultrasound parameters can be most accurately measured and best predict ovine fetal weight in late gestation. Singleton pregnancies were established using embryo transfer in 32 adolescent ewes, which were subsequently overnourished to produce fetuses of variable size (1720-6260 g). Ultrasound measurements at 126-133 days gestation were compared with fetal weight/biometry at late-gestation necropsy (n = 19) or term delivery (n = 13). Abdominal circumference (AC) and renal volume (RV) correlated best with physical measurements (r = 0.78-0.83) and necropsy/birth weight (r = 0.79-0.84). Combination of AC + RV produced an estimated fetal weight equation [Log EFW = 2.115 + 0.003 AC + 0.12 RV - 0.005 RV2] with highest ...
DailyMed - VALPROIC ACID capsule
Risk Summary For use in prophylaxis of migraine headaches, valproate is contraindicated in women who are pregnant and in women of childbearing potential who are not using effective contraception [see Contraindications (4)].. For use in epilepsy or bipolar disorder, valproate should not be used to treat women who are pregnant or who plan to become pregnant unless other medications have failed to provide adequate symptom control or are otherwise unacceptable [see Boxed Warning and Warnings and Precautions (5.2, 5.3)]. Women with epilepsy who become pregnant while taking valproate should not discontinue valproate abruptly, as this can precipitate status epilepticus with resulting maternal and fetal hypoxia and threat to life.. Maternal valproate use during pregnancy for any indication increases the risk of congenital malformations, particularly neural tube defects including spina bifida, but also malformations involving other body systems (e.g., craniofacial defects including oral clefts, ...

Imaging the Infant or Child with an Abnormal Head Circumference | American Academy of Pediatrics
The assessment of an infant or child with an abnormal head circumference commonly includes imaging of the head with neurosonography, computed tomography (CT), or magnetic resonance imaging (MRI). The choice of imaging modality depends on the patients age, presentation, clinical condition, and suspected underlying abnormality.. Macrocephaly, a head circumference more than 2 SD above the mean, or more than the 98th percentile for patient age, is a nonspecific finding. It may reflect benign enlargement of the subarachnoid spaces or may herald a significant intracranial abnormality: an extra-axial collection, a hydrocephalus, or a developmental, metabolic, neoplastic, posttraumatic, or infectious etiology.. Microcephaly, a head circumference more than 2 SD below the mean, or less than the third percentile for patient age, may be primary or secondary, acquired or genetic. Common causes include chromosomal abnormalities, intrauterine infection, intrauterine ischemia, maternal exposure to drugs and ...

The association of maternal pregnancy complications and sudden infant by Patricia D. Myers
Sudden Infant Death Syndrome (SIDS) is the third leading cause of infant mortality between birth and the first year of life in the United States. Along with the identification of various maternal risk factors, the role of fetal hypoxia has been hypothesized to be one of many causal factors associated with SIDS. The purpose of this study was to develop a profile of the SIDS infant and assess whether six pregnancy complications consistent with fetal hypoxia were associated with the increased outcome of SIDS. The secondary data analysis of Florida linked birth to death certificate data specific to Hillsborough County and Duval County were analyzed retrospectively for the period of time between 1998 and 2000. Of the 86, 342 births, 69 SIDS cases were identified, 34 in Hillsborough County and 35 in Duval County. A majority of the infants were White males with an average age of death of 80 days. The Chi-Square test for Independence with Cramers V, odds ratios and 95% confidence intervals were calculated to
IMOP: randomised placebo controlled trial of outpatient cervical ripening with isosorbide mononitrate (IMN) prior to induction...
BACKGROUND: There is increasing interest in carrying out pre-induction cervical ripening on an outpatient basis. However, there are concerns about the use of prostaglandins, the agents commonly used in hospital settings for this indication, because prostaglandins induce uterine contractions that may lead to fetal hypoxia. Indeed, in a recent study we demonstrated abnormalities in 9% of fetal heart rate tracings performed following prostaglandin induced cervical ripening at term. In contrast, we confirmed in the same study that isosorbide mononitrate (IMN) (administered on an inpatient basis) was both effective in inducing cervical ripening at term, and was associated with no associated fetal heart rate abnormalities. METHODS/DESIGN: The aim of this study is to determine whether IMN self administered by women on an outpatient basis improves the process of induction of labour. Specifically, we hypothesise that the use of outpatient IMN will result in a shorter inpatient stay before delivery, ...

Chapter 1 Fetal Asphyxia: Section A Introduction and John Little | obstetrical pathology
Introduction Asphyxia in modern English is another term for suffocation, the failure of respiratory gas exchange. In the fetus, this suffocation occurs because of a failure of gas exchange between the fetal blood in the placenta and the maternal uterine blood perfusing the placenta. The effect of asphyxia is a lowering of tissue oxygen…

Prenatal hypoxia induces increased cardiac contractility on a background of decreased capillary density. - ePrints Repository
Results: CHU significantly increased body mass (P , 0.001) compared with age-matched control rats but was without effect on relative cardiac mass. For incremental increases in left ventricular balloon volume, diastolic pressure was preserved. However, systolic pressure was significantly greater following CHU for balloon volume = 50 μl (P , 0.01) and up to 200 μl (P , 0.05). For higher balloon volumes systolic pressure was not significantly different from control. Developed pressures were correspondingly increased relative to controls for balloon volumes up to 250 μl (P , 0.05).Left ventricular free wall capillary density was significantly decreased in both epicardium (18%; P ,0.05) and endocardium (11%; P , 0.05) despite preserved coronary flow. Western blot analysis revealed no change to the expression of SERCA2a or nNOS but immuno-detectable eNOS protein was significantly decreased (P , 0.001) in cardiac tissue following chronic hypoxia in utero ...
Correlation of the one-minute Apgar score and the pH value of umbilical arterial blood
The one-minute Apgar score, proven useful for rapid assessment of the neonate, is often poorly correlated with other indicators of intrauterine well-being. Fetal asphyxia is directly associated with neonatal acidosis. A low Apgar score in the face of normal pH and base deficit does not, therefore, i …
Cadiotocography Combined With ST-analysis Versus Cardiotocography Combined With Scalp-pH - Tabular View - ClinicalTrials.gov
The value of STAN (ST analysis) was assessed in 2 randomized trials and shows: 1) A reduction in the incidence of severe hypoxia in fetuses during labor and 2) A reduction in frequency of redemption with suction and caesarean section due to lack of oxygen during the birth process.. Within the last year however, there is substantial new information regarding. STAN. The Swedish Social Board has published a newsletter (17) which describes a possible risk of birth of asphyxiated children, some died and others have cerebral palsy. A new Finnish study (18) suggests that there may be an increased risk of (moderate) acidosis after using STAN.. The above has led to considerable debate, not just in Sweden but also throughout Europe. This has led to the Swedish, Danish (Newsletter 1, Annex 1b) and the common Nordic reference group for STAN orally has announced new clinical guidelines for STAN application. A recently held workshop in Utrecht, Holland will generate joint European guideline, these will be ...

Lamaze for Parents : Forums : Info about cerebral palsy
You are correct. The current wisdom is that most cases of cerebral palsy have origins other than intrapartum events, although it is certainly also possible that the normal stress of labor or the excessive stress of induced or augmented labor could overwhelm a compromised babys ability to compensate. Research obstetricians have been trying to come up with a set of symptoms indicative of intrapartum hypoxia so as to identify those cases of neurologic injury that can be attributed to labor events. Leaving aside acute events such as uterine scar rupture, tetanic contractions, or umbilical cord prolapse, this isnt as easy as you would think. Neonatal seizure, for example, can be precipitated by overheating due to maternal fever, hyponatremia (low blood sodium) from too much IV fluid with insufficient salt, infection, congenital abnormality, etc. Other symptoms such as abnormal fetal heart rate or low blood pH at birth have very low predictive value for long-term outcome. In fact, those symptoms may ...

Effects of long-term hypoxia of intracellular pH and membrane potential of cultured rat carotid body glomus cells. He Shufang. Shanghai Brain Research Institute, Chinese Academy of Sciences. Shanghai 200031. Abstract. Spraque-Dawley(SD) rats(weighing about 100 g) were kept in a decompression chamber for 7--10 days. Then the carotid bodies were removed from the anesthetized animals and dissociated to obtain individuals or small clusters of glomus cells. These cells were cultured under hypoxic condition(11% O_(2), 5% CO_(2), 84% N_(2))for 2--3days. Control samples from normal SD rats(normoxic rat)were cultured in normoxic(21% O_(2), 5% CO_(2), 74%N_(2))or hypoxic conditions. Intracellular pH(pHi) and membrane potential(MP)of glomus cells of both the groups were simultaneously measured with pH-sensitive and conventional microelectrodes. Long-term hypoxia decreased pHi and increased MP of the cultured glomus cells to a degree far greater than acute hypoxia did; The mean pHi and MP of the glomus ...
Handbook ctg interpretation patterns physiology | Obstetrics and gynecology, reproductive medicine | Cambridge University Press
This book promotes an evidence-based paradigm of fetal heart rate monitoring during labour, with a move away from the traditional pattern-based interpretation to physiology-based interpretation. Chapters are presented in a systematic and accessible format, covering topics such as non-hypoxic causes of fetal brain injury, pre-existing hypoxia, types of intrapartum hypoxia, erroneous monitoring of maternal heart rate, fetal scalp blood sampling and fetal ECG (STAN), intermittent auscultation and medico-legal issues. Sections on pearls and pitfalls highlight good practice and common errors to promote best practice. End-of-chapter exercises allow the reader to engage with the theory and test their knowledge of key areas. This is a highly practical manual aimed at obstetricians and midwives, particularly those undergoing CTG training. The book will also be very useful to midwifery and medical students and to all those involved in multiprofessional intrapartum care. ...
Maternal-fetal HLA sharing and risk of newborn encephalopathy and seizures: a pilot study. - Semantic Scholar
A pilot case-control study was done to collect data on whether susceptibility to newborn encephalopathy and neonatal seizures is influenced by the degree of maternal-fetal sharing of HLA antigens. Cases included 13 infants with moderate or severe newborn encephalopathy and seven infants with neonatal seizures but no other signs of encephalopathy. Controls were neurologically normal infants matched to cases by date of birth, sex, race, and payment status. Infants and their mothers were typed for HLA-A, -B, -DR, and -DQ antigens. The observed frequency of sharing of maternal antigens was greater than expected (ie, 0.5) for cases compared to controls at the HLA-B, -DR, and -DQ loci but not for HLA-A. The risk of neurologic problems in the neonatal period was increased 6.3 times when there was more than one match at the HLA-DR or -DQ locus. Placental abnormalities were noted at delivery only among cases, and the mean placental weight in cases was 598 g versus 695 g in controls. Further studies with sample
Papers pp 1549,1544. Neonatal encephalopathy is a significant problem. The United States collaborative perinatal project studied 39 000 infants born with birth weights greater than 2500 g and found that 70% of the infants who showed early neonatal depression and encephalopathy died or were disabled.1 For many years it was accepted that fetal asphyxia during labour was the major cause of both neonatal encephalopathy and cerebral palsy. However, the evidence for this is surprisingly thin. Diagnosis of cerebral hypoxia-ischaemia during labour is difficult and is usually inferred from non-specific signs, such as low Apgar scores or seizures observed after delivery. More precise assessment using specialist technologies like magnetic resonance is possible but not widely available,2 and a working diagnosis of hypoxic-ischaemic encephalopathy may sometimes be applied with less than irrefutable proof of its presence. Nevertheless, several large studies have been unable to show significant perinatal ...
