Explaining words and acronyms you might find on this and other “birthy” blogs

Asynclitic  – A variation of normal, this is when the baby’s head is slightly tilted during labor and/or birth.

CPDcephalopelvic disproportion.  It is a diagnosis that means the care provider suspects that a baby’s head size is incompatible with the pelvis size.  It is commonly used as a reason for cesarean birth.  (Many of the women in this project were diagnosed with CPD and then went on to vaginally birth bigger babies in subsequent pregnancies.  See VBAC categories for those stories.)

EDD Estimated due date.  A healthy, full-term baby may arrive in a range between 37-42 weeks gestation.  A 40 week date is given as a median between those dates.  A baby is not considered “overdue” medically until the pregnancy goes beyond 42 weeks gestation.

EpisiotomyAn incision on the perineum (skin between vagina and rectum) which used to be routinely done during the pushing phase of birth.  This practice is falling out of favor with many care providers but is still used routinely by some.

GDGestational Diabetes.  It is diagnosed when a woman develops diabetes during pregnancy.  It is often associated with large newborns.

HBAC An acronym which means “home birth after cesarean”.

Nuchal ArmA variation of normal, this is when one or both of baby’s arms are up near the face or behind the head when born

“OA” or “Anterior” Presentation – Many consider optimal positioning to be where the baby is “occiput anterior” (OA), or where the back of the head (occiput) is on the side of mother’s belly, and facing the Mother’s spine.

“OP” or “Posterior” Presentation – Posterior presentation is a variation of normal that can cause discomfort and/or prolong labor and pushing. Occiput posterior (OP) is where the baby is facing the Mother’s belly and the back of the head is on the side of the Mother’s spine. If posterior presentation was mentioned in the submission, it will be in the “Posterior Presentation” category.

Shoulder DystociaWhen during birth the baby’s shoulder requires maneuvering to be freed from the Mother’s pubic bone.  There are many different protocols for dealing with this scenario and most do not cause trauma to Mother or Baby.

VBACAn acronym which means “vaginal birth after cesarean”.

VBA2C –  An acronym which means “vaginal birth after 2 cesareans”.

VBA3CAn acronym which means “vaginal birth after 3 cesareans”.

Weeks Gestation/Gestational Age – The number of weeks since the Mother’s last menstrual period. “Full Term” is a range of 37-42 weeks gestation.
