Asynclitism meaning

An asynclitic birth or asynclitism are terms used in obstetrics to refer to childbirth in which there is malposition of the head of the fetus in the uterus , relative to the birth canal. Many babies enter the pelvis in an asynclitic presentation, and most asynclitism corrects spontaneously as part of the normal birthing process. Fetal head asynclitism may affect the progression of labor, increase the need for obstetrical intervention, and may be associated with difficult instrumental delivery. When the self-correction does not occur, obstetrical intervention is necessary to deliver the child. Persistence of asynclitism can cause problems with dystocia , and has often been associated with cesarean births. However, with a skilled midwife or obstetrician a complication-free vaginal birth can sometimes, though not necessarily, be achieved through movement and positioning of the birthing person, and patience and extra time to allow for movement of the baby through the pelvis and moulding of the skull during the birthing process if this is safe in the circumstances. Other options include the use of vacuum-assisted delivery and forceps. Asynclitism can be digitally diagnosed using intrapartum ultrasound through the transabdominal cavity and the transperitoneal cavity. Intrapartum ultrasonography is regularly used during pregnancy to constantly monitor the fetal position within the mother's belly. Asynclitism is most easily diagnosed during labor when the cervix is opened allowing the orientation of the occiput , the back of the fetal head, to be visually assessed in relation to the mother's pelvis. The most common and preferred type of asynclitism is the left occiput anterior asynclitism because the baby's head enters the pelvis in such a way that it minimizes the circumference of how the baby exits the body as much as possible. In this type of asynclitism, it allows the fetus to be in the most efficient position.

The following studies were identified: 8 book chapters, 14 studies on asynclitism alone and 10 papers on both fetal occiput posterior position and asynclitism.

With an early diagnosis of fetal head malposition, the option of an operative vaginal delivery OVD might be contemplated by some, while others prefer to go the way of a cesarean section to avoid the potential risks associated with OVD [ 23 ].
