How do you assess macrosomia?

If your health care provider suspects fetal macrosomia, he or she might perform antenatal testing, such as a nonstress test or a fetal biophysical profile, to monitor your baby’s well-being. A nonstress test measures the baby’s heart rate in response to his or her own movements.

Is macrosomia a reason for C section?

Fetal macrosomia, arbitrarily defined as a birth weight of more than 4,000 g (8 lb, 13 oz) complicates more than 10 percent of all pregnancies in the United States. It is associated with increased risks of cesarean section and trauma to the birth canal and the fetus.

Can macrosomia be treated?

Objective: Treatment of fetal macrosomia presents challenges to practitioners because a potential outcome of shoulder dystocia with permanent brachial plexus injury is costly both to families and to society. Practitioner options include labor induction, elective cesarean delivery, or expectant treatment.

What defines macrosomia?

DEFINITION. Macrosomia refers to growth beyond a specific threshold, regardless of gestational age. In high income countries, the most commonly used threshold is weight above 4500 g (9 lb 15 oz), but weight above 4000 g (8 lb 13 oz) is also commonly used [1-5].

How many grams is considered macrosomia?

The term fetal macrosomia implies fetal growth beyond a specific weight, usually 4,000 g (8 lb, 13 oz) or 4,500 g (9 lb, 4 oz), regardless of the fetal gestational age. Results from large cohort studies support the use of 4,500 g as the weight at which a fetus should be considered macrosomic.

Will I be induced if baby is measuring big?

So, in the U.S., most people have an ultrasound at the end of pregnancy to estimate the baby’s size, and if the baby appears large, their care provider will usually recommend either an induction or an elective Cesarean.

Do they induce for macrosomia?

Suspected fetal macrosomia is not an indication for induction of labor, because induction does not improve maternal or fetal outcomes. Labor and vaginal delivery are not contraindicated for women with estimated fetal weights up to 5,000 g in the absence of maternal diabetes.

When is macrosomia detected?

A baby who is diagnosed as having fetal macrosomia weighs more than 8 pounds, 13 ounces (4,000 grams), regardless of his or her gestational age. About 9% of babies worldwide weigh more than 8 pounds, 13 ounces.

Is macrosomia the same as LGA?

Fetal Macrosomia LGA refers to neonatal birth weight larger than the 90th percentile for a given gestational age. In contrast to LGA, fetal macrosomia is defined as an absolute birth weight above a specified threshold regardless of gestational age.

Will they induce for macrosomia?

When did ACOG issue fetal macrosomia practice guidelines?

The Committee on Practice Bulletins—Obstetrics of the American College of Obstetricians and Gynecologists (ACOG) has issued new clinical management guidelines on fetal macrosomia. ACOG Practice Bulletin No. 22, which replaces Technical Bulletin No. 159 issued in September 1991, appears in the November 2000 issue of Obstetrics and Gynecology.

Are there any clinical interventions for suspected macrosomia?

Clinical Intervention. Clinical interventions for the treatment of suspected macrosomia (in pregnant women without diabetes) have not been reported. In pregnancies complicated by diabetes, one small clinical trial evaluated the effect of dietary intervention with or without the addition of insulin.

What is purpose of ACOG Practice Bulletin 173?

The purpose of this document is to quantify those risks, address the accuracy and limitations of methods for estimating fetal weight, and suggest clinical management for a pregnancy with suspected fetal macrosomia. The diagnosis of fetal macrosomia is imprecise.
