Fetal Circulation01:14

Fetal Circulation

4.9K
Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

Ultrasonography

8.4K
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...

IntroductionUltrasonography, or renal ultrasound, is a noninvasive medical imaging technique that uses high-frequency sound waves to visualize the kidneys, ureters, bladder, and surrounding tissues.Indications for Urinary System UltrasonographyUrinary system ultrasonography is indicated in various clinical scenarios, such as:Kidney Stones (Urolithiasis): To detect and monitor the size and presence of kidney or urinary tract stones.Hydronephrosis: To assess the dilation of the renal pelvis and...

Summary
This summary is machine-generated.

Intrapartum sonographic weight estimation (WE) systematically underestimates fetal weight. Formulas using biparietal diameter (BPD) for head measurement offer the most accurate results for fetal weight assessment during labor.

Area of Science:

  • Obstetrics and Gynecology
  • Medical Imaging
  • Fetal Medicine

Background:

  • Accurate fetal weight estimation is crucial for managing labor and delivery.
  • Sonographic weight estimation (WE) is commonly used, but its accuracy during labor requires further evaluation.

Purpose of the Study:

  • To assess the accuracy of intrapartum sonographic weight estimation (WE).
  • To compare the performance of different WE formulas during labor.

Main Methods:

  • Retrospective analysis of 1958 singleton pregnancies with cephalic presentation undergoing vaginal delivery.
  • Comparison of intrapartum WE with a control group (n=392) delivered by cesarean section.
  • Evaluation of five common WE formulas using mean percentage error (MPE) and median absolute percentage error (MAPE).

Main Results:

  • All formulas showed systematic underestimation of fetal weight (negative MPEs) in the intrapartum group.
  • The Hadlock II formula (using BPD, AC, FL) demonstrated the best performance (MPE: -1.28, MAPE: 6.52).
  • Significant differences in MPEs were observed between intrapartum and control groups for all formulas.

Conclusions:

  • Intrapartum sonographic weight estimation (WE) tends to underestimate fetal weight.
  • Formulas incorporating biparietal diameter (BPD) as the sole head measurement provide the most accurate fetal weight estimations during labor.
