In obstetrics, Leopold maneuvers are a common and systematic way to determine the position of a fetus inside the woman's uterus. They are named after the gynecologist Christian Gerhard Leopold. They are also used to estimate term fetal weight. [1] The maneuvers consist of four distinct actions, each helping to determine the position of the fetus.
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 .
By about week 21, the fetus begins to develop a regular schedule of movement. [17] The startle reflex is present in half of all fetuses by week 24 and in all fetuses by week 28. [19] Movement is restricted around this time because the fetus has grown so large it has little space for kicking or changing body position. [20]
Fetal position (British English: also foetal) is the positioning of the body of a prenatal fetus as it develops. In this position, the back is curved, the head is bowed, and the limbs are bent and drawn up to the torso. A compact position is typical for fetuses. Many newborn mammals, especially rodents, remain in a fetal position well after birth.
They may also be referred to as delivery positions or labor positions. In addition to the lithotomy position (on back with feet pulled up), still commonly used by many obstetricians , other positions are successfully used by midwives and traditional birth-attendants around the world.
A preterm birth, also known as premature birth, is defined as babies born alive before 37 weeks of pregnancy are completed. [40] There are three types of preterm births: extremely preterm (less than 28 weeks), very preterm (28 to 32 weeks) and moderate to late preterm (32 to 37 weeks). [40]
Quickening indicates the start of fetal movements, usually felt 14–26 weeks after conception, or between the fourth and sixth month. [ 5 ] [ 6 ] A woman pregnant for the first time (i.e., a primigravida woman) typically feels fetal movements at about 20–21 weeks, whereas a woman who has given birth at least once will typically feel ...
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).
