An Extremely Macrosomia Born Weighted 6.14 kg: Case Report and Review of the Literatures

ABSTRACT

Infants, born with a birth weight above 4.0 kg, are categorized as high birth weight infant (HBWI). The term HBWI is often used in similar context with macrosomia. Macrosomia is associated with many complications, and is considered to be a high risk group that requires an intensive care in most cases. This report is presenting an extreme macrosomia born at a gestational age of 38+5 weeks, with a body weight of 6.14 kg. The infant was born by a cesarean section from a mother with diabetes, and was admitted into an intensive care unit with tachypnea, which had occurred soon after birth. There were other complications, such as hypoglycemia, hypocalcemia, secondary atrial septal defect, patent ductus arteriosus, pulmonary hypertestion, and etc. With conservative management, the symptoms improved over a 10 day course and the patient was discharged from the hospital. To this day, the child has not presented with further health problems during the 6 months of follow up period. We reviewed the frequency and trend of the births of HBWI, through the raw data from the Statistics Korea on births between 2000 and 2010. With additional analysis of the cases of macrosomia, through the years of 1964 to 2011, we were able to find 7 reports, including this current case of infants born with a body weight above 6.0 kg. This case was the fifth heaviest infant among these 7 cases. We are reporting this case with the hope that it may contribute to the future care of high risk infants in a neonatal intensive care unit.
