Diagnostic ultrasound studies of the fetus are generally considered to be safe during pregnancy. However, this diagnostic procedure should be performed only when there is a valid medical indication, and the lowest possible ultrasonic exposure setting should be used to gain the necessary diagnostic information under the "as low as reasonably ...
Ultrasound is defined by the American National Standards Institute as "sound at frequencies greater than 20 kHz". In air at atmospheric pressure, ultrasonic waves have wavelengths of 1.9 cm or less. Ultrasound can be generated at very high frequencies; ultrasound is used for sonochemistry at frequencies up to multiple hundreds of kilohertz.
While 3D is popular with parents desiring a prenatal photograph as a keepsake, [7] both 2D and 3D are discouraged by the FDA for non-medical use, [8] but there are no definitive studies linking ultrasound to any adverse medical effects. [9] The following 3D ultrasound images were taken at different stages of pregnancy:
It's been known that smoking while pregnant can harm babies, and now researchers in England believe they've been able to show the effects using ultrasound scans. Researchers at Lancaster and ...
Essentially, ultrasound is considered safe. While other imaging modalities use radioactive dye or ionizing radiation, for example, ultrasound transducers send pulses of high frequency sound into the body and then listen for the echo. In summary, the primary risks associated with ultrasound would be the potential heating of tissue or cavitation ...
An elevated level of stress during pregnancy leads to notorious pregnancy outcomes, including preterm birth, low birth weight, and mental health problems for the mother. Prolonged effects of chronic stressors such as discrimination, intimate partner violence, housing issues, and poverty lead to widespread maternal health issues and adverse ...
Side effects include irregular periods, benign ovarian cysts, pelvic pain, and depression. [2] Rarely uterine perforation may occur. [2] Use is not recommended during pregnancy but is safe with breastfeeding. [2] The IUD with progestogen is a type of long-acting reversible birth control. [5]
Fluid restriction is also used to help limit excess water in the body. Using diuretics during pregnancy needs to be done carefully, as diuretics can impair blood flow to the placenta which could potentially cause harm to the fetus. Hydrochlorothiazide and furosemide are safe during pregnancy and breastfeeding. [7]
