Assessing a newborn baby right after birth is a crucial duty for every midwife working in a Nigerian health facility. This initial check helps confirm that the baby is transitioning smoothly from life inside the womb to the outside world. Midwives look for any signs of congenital abnormalities or birth injuries that might need urgent medical attention. The process begins with a quick, general overview known as the Apgar score at one and five minutes of life, followed by a more detailed head-to-toe physical examination within the first twenty-four hours. Setting up a warm, well-lit environment prevents newborn hypothermia during this sensitive procedure.
A healthy term newborn born between 37 and 42 weeks of gestation displays several distinct physical traits. The head is relatively large compared to the rest of the body, often showing some degree of molding due to passage through the birth canal.
Newborn skin presents a variety of temporary marks and color changes that often worry new mothers in the maternity ward. Midwives must distinguish harmless physiological variations from pathological signs of illness like jaundice or cyanosis.
Taking body measurements provides objective data on a newborn's physical growth and nutritional status. These measurements serve as a baseline for pediatric care and help identify babies who are small or large for their gestational age.
Accuracy in anthropometry depends heavily on the midwife's technique and proper equipment calibration. Before placing the baby on a weighing scale, the scale must be balanced to zero, and a clean paper liner placed to prevent cross-infection. The baby is weighed completely naked without clothes or a wet diaper. For length, a firm measuring board with a fixed headpiece and movable footpiece gives the most reliable results, requiring two people to ensure the baby's legs are straight and flat. Head circumference is measured using a non-stretchable tape passed over the most prominent part of the occiput and just above the eyebrows.
Raw measurements alone do not tell the whole story; they must be plotted on standardized growth charts such as the WHO growth standards. These charts categorize babies into percentiles based on weight, length, and head circumference for their gestational age. Infants falling below the 10th percentile are classified as small for gestational age, while those above the 90th percentile are large for gestational age. Midwives use these classifications to anticipate complications like hypoglycemia in small babies or shoulder dystocia risk factors in large infants.
Accurate record-keeping is a legal and professional requirement in Nigerian healthcare settings. Every physical characteristic observed and every anthropometric measurement taken must be entered clearly in the baby's case note and the child health card. Midwives must record the exact date, time, and values in standard metric units. Any abnormal finding, such as a heart murmur, asymmetry, or a weight significantly outside normal limits, must be reported immediately to the attending physician or senior medical officer for further evaluation.
