Muscarinic antagonists have widespread effects including actions on the iris and ciliary muscle of the eye, the heart and blood vessels, secretions of the respiratory tract, GI system, and salivary glands, GI motility, urinary bladder tone, and the central nervous system.
Agents having as their major action the interruption of neural transmission at nicotinic receptors on postganglionic autonomic neurons. Because their actions are so broad, including blocking of sympathetic and parasympathetic systems, their therapeutic use has been largely supplanted by more specific drugs. They may still be used in the control of blood pressure in patients with acute dissecting aortic aneurysm and for the induction of hypotension in surgery.

Neurological morbidity after fetal supraventricular tachyarrhythmia. (1/297)

BACKGROUND: Fetal tachyarrhythmia is a well-documented entity which, in the absence of pharmacological intervention, may lead to congestive heart failure, fetal hydrops and eventually fetal demise. The success rate of the implemented treatment is generally measured by survival and achievement of control of the arrhythmia. We report on the occurrence of associated cerebral damage in three patients with fetal tachycardia. METHODS: We describe three patients with a history of fetal supraventricular tachyarrhythmia who developed cerebral complications in utero. RESULTS: Two patients had cerebral hypoxic-ischemic lesions and one had hemorrhagic lesions present at birth. They had developed severe congestive heart failure and fetal hydrops secondary to fetal tachyarrhythmia, and there were no other obvious causes for the cerebral pathology. Two of these patients were referred to us antenatally. Therapy was instituted and resulted in control of the tachycardia and resolution of hydrops. The third patient was referred to our clinic shortly after birth because of severe circulatory problems secondary to fetal tachyarrhythmia. CONCLUSION: From these observations, we believe that a fetus with tachyarrhythmia and subsequent hydrops is at increased risk for the development of cerebral complications, due to the circulatory disturbances and sudden changes in heart rate which may lead to fluctuations in cerebral perfusion. This would imply that it is of the utmost importance to aim at immediate and complete control of the heart rate in the treatment of fetal tachyarrhythmia.  (+info)

Mechano- and chemoreceptor modulation of renal sympathetic nerve activity at birth in fetal sheep. (2/297)

Physiological responses at birth include increases in heart rate (HR), blood pressure, sympathetic nerve activity, and circulating vasoactive peptides. The factors mediating these responses are not known. To test the hypothesis that afferent input from peripheral mechanoreceptors (arterial and cardiopulmonary baroreceptors) and chemoreceptors contribute to the sympathoexcitatory and hormonal responses at birth, we studied the effects of sinoaortic denervation (SAD) and SAD with vagotomy (Vx) on changes in HR, mean arterial blood pressure (MABP), renal sympathetic nerve activity (RSNA), and catecholamine, arginine vasopressin (AVP), and ANG II levels at birth in term sheep. One hour after delivery by cesarean section, RSNA increased by 168 +/- 49 and 192 +/- 32% (relative to fetal values) in SAD and SAD-Vx animals, respectively. Significant increases in HR (18 +/- 5 and 20 +/- 6%) and MABP (24 +/- 4 and 20 +/- 5%) were also observed 1 h after delivery in SAD and SAD-Vx lambs, respectively. These responses are similar to those seen in intact sheep delivered at the same gestational age. AVP levels markedly increased after birth (19.8 +/- 6.7 to 136.1 +/- 75.9 pg/ml) in SAD-Vx lambs, whereas SAD animals displayed no change in AVP concentrations. Plasma ANG II also did not change after birth in either group, although levels were consistently higher (P < 0.01) in SAD compared with SAD-Vx animals. In the presence of SAD, Vx resulted in significantly greater plasma levels of norepinephrine, although levels did not change after birth in either group. The epinephrine responses at birth were similar in both groups of animals. The present data suggest that afferent input from peripheral chemoreceptors and mechanoreceptors contributes little to the hemodynamic and sympathetic responses after delivery by cesarean section. On the other hand, these peripheral mechanisms appear to be involved in modulating endocrine responses at birth.  (+info)

Interpretation of the electronic fetal heart rate during labor. (3/297)

Electronic fetal heart rate monitoring is commonly used to assess fetal well-being during labor. Although detection of fetal compromise is one benefit of fetal monitoring, there are also risks, including false-positive tests that may result in unnecessary surgical intervention. Since variable and inconsistent interpretation of fetal heart rate tracings may affect management, a systematic approach to interpreting the patterns is important. The fetal heart rate undergoes constant and minute adjustments in response to the fetal environment and stimuli. Fetal heart rate patterns are classified as reassuring, nonreassuring or ominous. Nonreassuring patterns such as fetal tachycardia, bradycardia and late decelerations with good short-term variability require intervention to rule out fetal acidosis. Ominous patterns require emergency intrauterine fetal resuscitation and immediate delivery. Differentiating between a reassuring and nonreassuring fetal heart rate pattern is the essence of accurate interpretation, which is essential to guide appropriate triage decisions.  (+info)

Fetal heart rate and umbilical artery velocity variability in pregnancies complicated by insulin-dependent diabetes mellitus. (4/297)

OBJECTIVES: To examine the variability in fetal heart rate and absolute flow velocity, which are possible hemodynamic markers of cardiovascular homeostasis in pregnancies complicated by diabetes mellitus. METHODS: Doppler studies of umbilical artery velocity waveforms were performed at 12-21 weeks of gestation in 16 women with well-controlled type I (insulin-dependent) diabetes mellitus. From umbilical artery velocity waveforms of at least 13 s in duration, we determined absolute values and beat-to-beat variability for fetal heart rate and umbilical artery flow velocities and compared these findings with normal controls matched for gestational age. RESULTS: Fetuses of diabetic women displayed increased fetal heart rate variability and umbilical artery peak systolic velocity. Fetal heart rate, umbilical artery time-averaged velocity and variability in umbilical artery flow velocity were not essentially different between the two groups. CONCLUSION: Fetal heart rate variability and umbilical artery peak systolic velocity may be markers for fetal cardiovascular homeostasis in pregnancies complicated by insulin-dependent diabetes mellitus.  (+info)

Bupivacaine augments intrathecal fentanyl for labor analgesia. (5/297)

BACKGROUND: fentanyl has been shown to be an effective analgesic for labor; this study investigated the analgesic effect of low-dose bpivacaine added to intrathecal fentanyl for labor analgesia METHODS: Ninety parturients in active labor who requested regional analgesia were randomized to receive an intrathecal injection of either fentanyl, 25 microg; bupivacaine, 1.25 mg, with fentanyl, 25 microg; or bupivacaine, 2.5 mg, with fentanyl, 25 microg, as part of a combined spinal-epidural technique. Visual analog pain scores were recorded before and at intervals after injection until the patient requested further analgesia. Maternal blood pressure and fetal heart rate were recorded before and at intervals after injection. Lower-extremity muscle strength was tested before and 30 min after injection; anesthetic level to cold sensation and the presence and severity of pruritus were recorded. RESULTS: Duration of analgesia was longer in the group receiving bupivacaine, 2.5 mg, and fentanyl, 25 microg, than the group receiving plain fentanyl (108 vs. 92 min; P < 0.05). Onset of analgesia was faster in both groups receiving bupivacaine compared with plain fentanyl (P < 0.05). No differences in muscle strength after injection were found in any group, although anesthetic levels to cold were documented in all patients in the bupivacaine groups, and 21 of 30 in the plain fentanyl group. Baseline fetal heart rates did not change after injection in any group, and maternal blood pressure was unchanged. CONCLUSIONS: The addition of 2.5 mg isobaric bupivacaine to 25 microg fentanyl for intrathecal labor analgesia modestly increases duration and speeds onset of analgesia compared with plain intrathecal fentanyl.  (+info)

Long-term prognosis of pregnancies complicated by slow embryonic heart rates in the early first trimester. (6/297)

Slow embryonic heart rates at gestational age 7 weeks or less are associated with high risk of first trimester death. Our goal was to determine the prognosis for those embryos with slow early heart rates who survive the first trimester. We prospectively recorded embryonic heart rates for all obstetrical sonograms obtained on singleton pregnancies at or before 7.0 weeks' gestation since 1993. We collected information about pregnancy outcome, including date of live birth or in utero death and presence and nature of congenital anomalies. First trimester survival rate was 61.6% among 531 embryos with slow early heart rates (< 100 bpm at < or = 6.2 weeks, < 120 bpm at 6.3 to 7.0 weeks), lower than the survival rate of 91.5% among 1501 embryos with normal heart rates (p < 10(-8), Fisher's exact test). Among 299 pregnancies in which the early heart rate was slow and the fetus was still alive at the end of the first trimester, 277 (92.6%) resulted in liveborn infants without congenital anomalies, similar to the frequency of 95.1% in cases with normal early heart rates (p > 0.10, Fisher's exact test). Structural and chromosomal anomalies, however, occurred more than twice as frequently in cases with slow early heart rates: 5.4% (16 of 299) of the first trimester survivors with slow early heart rates proved to have anomalies, as compared to 2.4% (31 of 1281) of cases with normal early heart rates (p < 0.05, Fisher's exact test). In conclusion, a pregnancy in which the embryo has a slow heart rate at or before 7.0 weeks' gestation and which continues beyond the first trimester has a high likelihood (> 90%) of resulting in a liveborn neonate without congenital anomalies. Embryos with slow early heart rates do, however, have a greater risk of having anomalies than embryos with normal early heart rates.  (+info)

Prenatal diagnosis of acute massive fetomaternal hemorrhage. (7/297)

We present here 2 cases of acute and 2 cases of chronic massive fetomaternal hemorrhage. A sinusoidal fetal heart rate pattern may indicate chronic fetomaternal hemorrhage, but, when increased variability is observed in fetal monitoring, maternal hemoglobin F should be measured to exclude acute fetomaternal hemorrhage.  (+info)

Positive outcome after preimplantation diagnosis of aneuploidy in human embryos. (8/297)

usromosomal abnormalities are responsible for a great deal of embryo wastage, which is reflected, at least partially, in decreased implantation and increased miscarriage in older women. To address this problem the transfer of only chromosomally normal embryos previously selected by preimplantation genetic diagnosis (PGD) has been proposed. We designed a multi-centre in-vitro fertilization (IVF) study to compare controls and a test group that underwent embryo biopsy and PGD for aneuploidy. Patients were matched retrospectively, but blindly, for average maternal age, number of previous IVF cycles, duration of stimulation, oestradiol concentrations on day +1, and average mature follicles. All these parameters were similar in test and control groups. Only embryos classified as normal for those chromosomes were transferred after PGD. The results showed that the rates of fetal heart beat (FHB)/embryo transferred between the control and test groups were similar. However, spontaneous abortions, measured as FHB aborted/FHB detected, decreased after PGD (P < 0.05), and ongoing pregnancies and delivered babies increased (P < 0.05) in the PGD group of patients. Two conclusions were obtained: (i) PGD of aneuploidy reduced embryo loss after implantation; (ii) implantation rates were not significantly improved, but the proportion of ongoing and delivered babies was increased.  (+info)

Relationship of maternal and fetal lactate levels and fetal heart rate changes with duration of second stage of labor Academic Article ...
Fetal heart rate recordings were examined in 953 patients with special reference to the different patterns occurring during labor. After delivery the infants were examined with special emphasis on evidence of growth retardation, defined as birthweight below the 10th percentile for the gestational age. Heart rate patterns of growth retarded infants were compared with those of normal newborns. A statistically significant increase in early, late, and variable decelerations was noted in infants with growth retardation. The difference in loss of beat to beat variation was not statistically significant. Also, as might have been expected, low Apgar scores were found more frequently in the small for gestational age infants.. ...

In the evening, the woman, accompanied by her husband, was admitted to the public hospital as she had started having contractions. A registered midwife was assigned to her care, and undertook an assessment at 11.20pm. The fetal heart rate (FHR) was adequate. The woman was assessed to be in latent labour, and the midwife suggested that the couple might wish to return home. They decided to stay in hospital.. At 12.45pm, the midwife documented that the womans contractions were approximately four minutes apart. The midwife left the delivery room at 1.30pm, instructing another midwife to respond if the couple rung the call bell.. Sometime between 1.30am and 2am, the man rang the ...
Per partum fetal asphyxia is a major cause of neonatal morbidity and mortality. Fetal heart rate monitoring plays an important role in early detection of acidosis, an indicator for asphyxia. This problem is addressed in this paper by introducing a novel complexity analysis of fetal heart rate data, based on producing a collection of piecewise linear approximations of varying dimensions from which a measure of complexity is extracted. This procedure specifically accounts for the highly nonstationary context of labor by being adaptive and multiscale. Using a reference dataset, made of real per partum fetal heart rate data, collected in situ and carefully constituted by obstetricians, the behavior of the proposed approach is analyzed and illustrated. Its performance is evaluated in terms of the rate of correct acidosis detection versus the rate of false detection, as well as how early the detection is made. Computational cost is also discussed. The results are shown to be extremely promising and further
TY - JOUR. T1 - Fetal heart rate, arterial pressure, and blood volume responses to cortisol infusion. AU - Wood, C. E.. AU - Cheung, C. Y.. AU - Brace, R. A.. PY - 1987. Y1 - 1987. N2 - The purpose of this study was to determine whether physiological amounts of cortisol affect the fetal cardiovascular system. Cortisol (4 μg/min) or the vehicle was infused intravenously for 5 h into six chronically catheterized sheep fetuses at 127-143 days gestation (term = 145-150 days). In the cortisol-infused animals, plasma cortisol concentration increased from 2.0 ± 0.6 (SE) to 8.3 ± 0.9 ng/ml. There was a concomitant decrease in fetal heart rate of 38 beats/min (P , 1 x 10-6) and an increase in arterial pressure. Estimated blood volume decreased by 6% in the cortisol-infused fetuses compared with the vehicle-infused animals (P , 1 x 10-4). In addition, plasma norepinephrine and epinephrine concentrations decreased to 70% of control at the end of the 5-h cortisol infusion, whereas plasma renin ...
This project is developing a set of recordings of fetal scalp electrograms and uterine muscular activity, with beat-by-beat annotations of the fetal ECG, to support studies of fetal heart rate variability.. Fetal distress may be due to intrapartum asphyxia or hypoxia. Correctly diagnosing fetal distress is essential for preventing fetal morbidity, as well as avoiding unnecessary cesarean sections. The OB-1 Database was collected to support development of a diagnostic system based on advanced signal processing of nonstationary signals recorded during electronic fetal monitoring. The contributors of the data (Nancy Oriol, Fred Bennet, and Prateek Aggarwal) have previously developed the signal processing technology for this purpose.

Information on fetal well-being during labor is of great importance to the managing physician. The current use of the fetal heart rate monitor provides some information on fetal condition, and is the primary tool used to determine if immediate operative delivery is required. The fetal pulse oximeter can provide additional information regarding fetal oxygen saturation.. Intervention: A fetal oxygen saturation sensor is placed in the uterus, between the fetal cheek or forehead and the uterine wall. In half of the patients, the managing physician will have access to fetal oxygen saturation and fetal heart rate monitoring. In the other half of the patients, labor will be monitored by fetal heart rate alone.. Study hypothesis: The additional information provided by the use of the fetal pulse oximeter will reduce the chances of a cesarean delivery. The primary outcome is cesarean section for any indication and secondary outcomes are cesarean delivery for non-reassuring fetal heart rate or dystocia, ...
A database of fetal heart rate (FHR) time series measured from 7 221 patients during labor is analyzed with the aim of learning the types of features of these recordings that are informative of low cord pH. Our highly comparative analysis involves extracting over 9 000 time-series analysis features from each FHR time series, including measures of autocorrelation, entropy, distribution, and various model fits. This diverse collection of features was developed in previous work [1]. We describe five features that most accurately classify a balanced training set of 59 low pH and 59 normal pH FHR recordings. We then describe five of the features with the strongest linear correlation to cord pH across the full dataset of FHR time series. The features identified in this work may be used as part of a system for guiding intervention during labor in future. This work successfully demonstrates the utility of comparing across a large, interdisciplinary literature on time-series analysis to automatically
A nonstress test (NST) measures the fetal heart rate in response to the fetus movements. Generally, the heart rate of a healthy fetus increases when the fetus moves. The NST is usually performed in the last trimester of pregnancy in a special prenatal testing area of the hospital, or in your doctors office. The NST uses continuous electronic fetal monitoring to record the fetal heart rate. The mother is instructed to push a button on the monitor each time she feels fetal movement. This places a mark on the paper printout. The NST usually lasts for 20 to 40 minutes. Test results of the NST may be reactive (normal), when there are two or more fetal heart rate increases in the testing period, or nonreactive, when there is no change in the fetal heart rate when the fetus moves. This can occur when the fetus is asleep, or when a fetus is too young or it may mean that there is a problem that requires further testing.. ...

Has anyone experienced their babys BPM fluctuating by 20 BPM? Friday I had my gallbladder removed at 16 weeks. They checked babys heart rate before surgery and his BPM was 140 after the surgery 137. Well, today I went in for my 16 week appointment and to check baby after Surgery again. Today his BPM was 160. Also, the nurse from L&D who checked fetal heart rate before and after surgery found heart beat on mid left side. This is also where they found baby via sonogram. My OB found heart beat lower right side at 20 BPM faster. My other two didnt fluctuate at all and I just thought that was odd. Id say If they just checked it after surgery that would explain it. But they checked before also and it was only two points higher.

Breastfeeding, 31 and older: 320 mg. There is some evidence that magnesium helps prevent the uterus from contracting too soon, though this is still inconclusive. Magnesium certainly helps prevent cramps, though.. Magnesium citrate, on the other hand, is something that the FDA recommends taking only when the benefits outweigh the risks.. In BJOG: An International Journal of Obstetrics and Gynaecology in August 2007, two studies are cited. The first study concluded:. Additional magnesium appeared to benefit the fetus during labour. Significantly fewer showed fetal heart rate irregularities, meconium-stained liquor and partogram abnormalities. The supplemented group also had fewer late stillbirths either before or during labour.. It must be stressed that these secondary findings, although of interest, need to be substantiated by further work. Until then, supplementation cannot be recommended but poorly nourished women should be encouraged to eat a diet that contains adequate magnesium, in ...

Early decelerations follow uterine contractions, and rarely drop below 100 bpm. They are a normal, vagal response to increased intracranial pressure. Late decelerations dont begin until 20-30 seconds after uterine contractions begin, and bottom out long after contractions have peaked - these are believed to be caused by myocardial ischemia secondary to uteroplacental insufficiency. Treatment should be with oxygenation, change of positioning, and fluid administration. If prolonged, the fetus may be at risk, attempts at monitoring the fetal acid-base status should be made, and urgent delivery should be considered. Variable decelerations are the most common form, and occur subsequent to umbilical cord compression. Their shape and onset are both highly variable, and heart rate may decrease to , 100 bpm. If frequent, or prolonged (2-10 minutes), variable decelerations can be a sign of danger.. Contractions should occur every 2-3 minutes in the active phase of labor, lasting ~ 1 min at a time and ...

For decades, this was the go-to boy or girl predictor. Many women around the world used this method to predict the sex of their baby. And, like with any other method, theres a 50-50 chance that the prediction is right.. Its very hard to truly consider a baby heart rate for a boy or girl when conducting any gender test.. As we discussed earlier, the heart rate of the child will be elevated during the early pregnancy, which would indicate that every baby is a girl. But this rate naturally comes down as pregnancy continues, and a rate of 130 ppm is not uncommon later on.. Logic alone isnt enough to prove that this method doesnt work. A medical study was conducted in 2006 to prove that the FHR rate during the first trimester is not significantly different between female or male babies. If youre using this method during the first trimester, theres a good chance that your prediction will be wrong.. Another study was conducted in the 1980s that looked at over 10,000 FHR, and found that embryonic ...
This study is important because it was performed before the technology was widely adopted, in contrast to fetal heart monitoring. A number of studies have shown that routine fetal heart monitoring, too, is no better at predicting fetal distress than a trained nurse with a fetoscope, but that it does increase a womans chance of having a C-section (not to mention that it constrains a womans movement during labor and that internal monitoring is an invasive procedure for both mother and fetus). Nonetheless, obstetricians have come to rely on fetal heart monitoring, and 85% of births are so monitored. The C-section rate rose again last year to 30.2% of all births, a 46% rate increase in a decade. (An editorial about the shortcomings of fetal heart monitoring, with references, is here ...

This method uses a thin wire (electrode) put on your babys scalp. The wire runs from the baby through your cervix. It is connected to the monitor. This method gives better readings because things like movement dont affect it. But it can only be done if the fluid-filled sac that surrounds the baby during pregnancy (amniotic sac) has broken and the cervix is opened. Your provider may use internal monitoring when external monitoring is not giving a good reading. Or your provider may use this method to watch your baby more closely during labor.. During labor, your healthcare provider will watch your uterine contractions and your babys heart rate. Your provider will note how often you are having contractions and how long each lasts. Because the fetal heart rate and contractions are recorded at the same time, these results can be looked at together and compared.. Your provider may check the pressure inside your uterus while doing internal fetal heart monitoring. To do this, he or she will put a ...
