Hypertension (Definition)

A blood pressure reading has two numbers: a systolic blood pressure and a diastolic blood pressure. The systolic blood pressure is the maximum pressure the blood exerts on the vessels when the heart is beating. The diastolic blood pressure is the pressure the blood exerts on the vessels in between heartbeats. Hypertension, or high blood pressure, begins when the systolic blood pressure remains above 140 or when the diastolic blood pressure remains above 90. Hypertension can be a result of increased blood flow through vessels or increased resistance to ...Read more

How does placenta previa cause preterm delivery?

How does placenta previa cause preterm delivery?

Bleeding and Cntrxns: Previa: Placenta overlies the cervix/birth canal. Gr 1 means placenta is close, Gr 4 means it's directly overlying/blocking the baby's exit -- high chance of preterm labor & bleeding; you'd need a C/S at 36-37wks. More common in woman w/ hx of C/S & smoking. Not much you can do but wait. If dx'ed early, the uterus still grows/stretches and a placenta can migrate away even in 3rd tri. Follow w/ US. ...Read more

35 weeks pregnant. 1cm dilated 30% effaced. Can sneezing cause further dilation? Scared of delivering preterm. :(

35 weeks pregnant. 1cm dilated 30% effaced. Can sneezing cause further dilation? Scared of delivering preterm. :(

No: 1 cm. dilated and 30% effaced is perfectly normal at 35 wk. gestation and sneezing will not cause dilatation or labor. Fortunately for those with seasonal allergies, sneezing is not a cause for preterm births. :) Your concern tells me how lucky this baby is to have you for a mom. Hope this helps and best wishes to you both. ...Read more

If high bp, what is risk for fetal injury from reduced placental perfusion secondary to vasospasm?

IUGR: Intrauterine growth retardation can be caused by decreased blood flow to the placenta. Asymmetric iugr has a better prognosis than symmetrical iugr, but every pregnacy is unique and you should discuss this with your ob. ...Read more

How can cesarean delivery be a possible risk factor for ttn or respiratory distress syndrome?

How can cesarean delivery be a possible risk factor for ttn or respiratory distress syndrome?

Not squeezed: Normal vaginal delivery squeezes some of the fluid in the lung spaces out during passage through the birth canal. C-sections alows that fluid to remain and thereby can cause a poor exchange of oxygen. Ttn uaually resolves on its own with supportive care. Ttn can also happen with a normal delivery but less often. ...Read more

Can preterm IVH have long-tern effects on mental health?Had grade 4 IVH as infant, no apparent neurological damage but severe anxiety.Related?

Can preterm IVH have long-tern effects on mental health?Had grade 4 IVH as infant, no apparent neurological damage but severe anxiety.Related?

Maybe. Maybe not.: Severe intraventricular hemorrhage usually means many brain cells died off... and would affect everything in the life of that person from that point onward, for better or for worse, but we hope for better rather than for worse. The question is, whether one's anxiety level would have been worse, would have been better, or would have been the same, without the IVH. Nobody can tell with certainty. ...Read more

Delivery by cesarean section is one of the predisposing factors of neonatal respiratory distress syndrome, why? And how?

Delivery by cesarean section is one of the predisposing factors of neonatal respiratory distress syndrome, why? And how?

??RDS??: I would agree more cs babies have respiratory pbs than regular delivery but the issue is ttn ( transient tachypnea of the newborn) not rds.A trip down the birth canal helps squeeze some of the lung fluid out before birth, which does not happen for cs. About 10% of cs will have to work hard to clear that fluid & may require o2 & special care in the process.It usually clears in < 48hr. ...Read more

Can placenta prevera lead to a preterm birth?

Can placenta prevera lead to a preterm birth?

It can: Placenta previa means that the placenta is blocking to cervix, which is the opening from the uterus to the vagina. If the cervix starts to open, heavy bleeding can occur, making it necessary to deliver early to protect mom's health. To reduce the risk of life-threatening bleeding, doctors may deliver early. ...Read more

Will having amnio cause preterm labor?

Will having amnio cause preterm labor?

It can.: Amniocentesis involves introducing a fine needle into the pregnancy sac to retrieve some amniotic fluid for fetal dna testing. That technique had inherent risks for complications, including preterm labor and preterm premature rupture of membranes. The risk for any of these complications to occur is <1%, but is real and devastating if they do occur. ...Read more
