Intrapartum ultrasonography is regularly used during pregnancy to constantly monitor the fetal position within the mother's belly. [6] The International Society of Ultrasound in Obstetrics and Gynecology Practice Guidelines recommend the use of intrapartum ultrasound to diagnose asynclitic births during prolonged and obstructed labors. [7]
The main causes of obstructed labour include a large or abnormally positioned baby, a small pelvis, and problems with the birth canal. [2] Both the size and the position of the fetus can lead to obstructed labor. Abnormal positioning includes shoulder dystocia where the anterior shoulder does not pass easily below the pubic bone.

abnormal birth position; asynclitic birth (asinclitismus) abnormal fetal attitude (extensor inserting head) obstetric turn; acceleration and stimulation of birth; breech presentation; forceps and vacuum extraction [5] While any number of injuries may occur during the birthing process, a number of specific conditions are well described.
Abnormal position of the baby, prematurity, twin pregnancy, multiple prior pregnancies [2] [3] Diagnostic method: Suspected based on a sudden decrease in baby's heart rate during labor, confirmed by seeing or feeling the cord in the vagina [4] Differential diagnosis: Abruptio placentae [2] Treatment: Rapid delivery, usually by cesarean section ...
In obstetrics, a cephalic presentation or head presentation or head-first presentation is a situation at childbirth where the fetus is in a longitudinal lie and the head enters the pelvis first; the most common form of cephalic presentation is the vertex presentation, where the occiput is the leading part (the part that first enters the birth canal).

Fetal abnormalities are conditions that affect a fetus or embryo, are able to be diagnosed prenatally, and may be fatal or cause disease after birth. They may include aneuploidies, structural abnormalities, or neoplasms. Acardiac twin; Achondrogenesis; Achondroplasia
They are referred to as upright birth positions. [3] Understanding the physical effects of each birthing position on the mother and baby is important. However, the psychological effects are crucial as well. Knowledge about birthing positions can help mothers choose the option they are most comfortable with.
In obstetrics, position is the orientation of the fetus in the womb, identified by the location of the presenting part of the fetus relative to the pelvis of the mother. Conventionally, it is the position assumed by the fetus before the process of birth, as the fetus assumes various positions and postures during the course of childbirth .
