Ultrasonography01:17

Ultrasonography

7.1K
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.
During an ultrasonography procedure, a handheld device called...

Regression Toward the Mean

6.7K
Regression toward the mean (“RTM”) is a phenomenon in which extremely high or low values—for example, and individual’s blood pressure at a particular moment—appear closer to a group’s average upon remeasuring. Although this statistical peculiarity is the result of random error and chance, it has been problematic across various medical, scientific, financial and psychological applications. In particular, RTM, if not taken into account, can interfere when...

Summary
This summary is machine-generated.

Inaccurate fetal weight estimates during pregnancy, often due to breech presentation or non-lateral spine position, are linked to increased neonatal intensive care unit admissions. Accurate sonographic estimated fetal weight (EFW) is crucial for predicting neonatal outcomes.

Area of Science:

  • Obstetrics and Gynecology
  • Perinatology
  • Medical Ultrasound

Background:

  • Accurate estimation of fetal weight (EFW) is critical for managing pregnancies and predicting neonatal outcomes.
  • Deviations in sonographic EFW can indicate potential complications.
  • Understanding factors influencing EFW accuracy is essential for clinical practice.

Purpose of the Study:

  • To identify parameters associated with significant deviations in sonographic estimated fetal weight (EFW).
  • To evaluate the impact of inaccurate EFW on labor and neonatal outcomes.

Main Methods:

  • A retrospective case-control study compared 177 pregnancies with sonographic EFW deviations (±20%) to 354 accurate EFW pregnancies (±1%).
  • Data collected included ultrasound parameters (placental location, fetal presentation, spine position) and pregnancy outcomes.
  • Multivariate analysis was used to identify independent risk factors for EFW inaccuracies and adverse outcomes.

Main Results:

  • Inaccurate EFW groups had lower gestational age and birth weight, higher rates of breech presentation, and lower rates of anterior placenta.
  • Non-lateral spine position was an independent risk factor for inaccurate EFW (OR=2.505).
  • Inaccuracy in sonographic EFW was an independent risk factor for neonatal intensive care unit (NICU) admission (OR=2.4) and respiratory complications.

Conclusions:

  • Sonographic EFW accuracy is influenced by fetal presentation, spine position, and placental location.
  • Inaccurate EFW is associated with adverse neonatal outcomes, including increased NICU admissions.
