"Newborn Check Up" by Unknown CC BY 2.0/Cropped from original
The time of birth is the precise time when the entire body is out of the mother and must be recorded. In the case of multiple births, each birth is noted in the same way. If the mother’s and newborn’s conditions allow, immediate skin-to-skin contact and delayed cord clamping are likely to be implemented. A cap is placed on the newborn’s head, wet blankets are removed, and the baby and woman are covered with fresh warm blankets. It is currently recommended that the umbilical cord not be clamped until one to five minutes after birth, or until after the cord stops pulsating, to allow physiologic transfer of blood to the newborn. The optimal duration of delayed cord clamping appears to be up to three minutes unless the cord stops pulsating sooner. The delayed cord clamping allows for a placental transfusion of up to 30% of the total fetal–placental blood volume 2.5 cm above the clamp. In another approach, referred to as lotus birth, the cord is not clamped and cut at all. Instead, the cord and placenta remain attached to the baby until the cord naturally separates from the baby several days after birth.
Care given immediately after birth focuses on assessing and stabilizing the newborn. The Neonatal Resuscitation Program (NRP) and AWHONN recommend that at least two nurses be present for each birth. One nurse is responsible for the care of the newborn while the other helps the nurse–midwife or physician with the delivery of the placenta and care of the mother. The nurse performs a brief assessment of the newborn immediately even while skin-to-skin contact is being performed. Assessment includes assigning Apgar scores at one and five minutes after birth.
Major priorities for immediate newborn care include:
Maintaining a patent airway
Supporting respiratory effort
Preventing cold stress by drying and preferably covering the newborn with a warmed blanket while on the mother’s abdomen/chest or, less optimally, placing them under a radiant warmer
The neonatal period includes the time from birth through day 28 of life. During this time, the neonate or newborn must make many physiologic and behavioral adaptations to extrauterine life. Physiologic adjustment tasks are those that involve:
Establishing and maintaining respirations
Adjusting to circulatory changes
Regulating temperature
Ingesting, retaining, and digesting nutrients
Eliminating waste
Regulating weight
Behavioral tasks include:
Establishing a regulated behavioral tempo independent of the mother, which involves self-regulating arousal, self-monitoring changes in state, and patterning sleep
Processing, storing, and organizing multiple stimuli
Establishing a relationship with caregivers and the environment

Major adaptations associated with transition from intrauterine to extrauterine life occur during the first six to eight hours after birth. A predictable series of events during transition are mediated by the sympathetic nervous system and result in changes that involve heart rate, respirations, temperature, and gastrointestinal (GI) function. The transition period represents a time of vulnerability for the newborn and warrants careful observation.
The first stage of the transition period lasts up to 30 minutes after birth and is called the first period of reactivity.
The newborn’s heart rate increases rapidly to 160 to 180 beats/min but gradually falls after 30 minutes or so to a baseline rate of 100 to 120 beats/min. Respirations are irregular, with a rate between 60 and 80 breaths/min. Fine crackles can be heard on auscultation. Audible grunting, nasal flaring, and retractions of the chest also can be present, but these should cease within the first hour after birth. The infant is alert and may have spontaneous startles, tremors, crying, and head movement from side to side. Bowel sounds are audible, and meconium may be passed.
After the first period of reactivity, the newborn either sleeps or has a marked decrease in motor activity. This period of decreased responsiveness lasts from 60 to 100 minutes.
The infant is pink, respirations are rapid (up to 60 breaths/min) and shallow but unlabored, bowel sounds are audible, and peristaltic waves may be noted over the rounded abdomen.
The second period of reactivity occurs approximately between two and eight hours after birth and lasts from 10 minutes to several hours. Brief periods of tachycardia and tachypnea may occur. The infant may also present increased muscle tone, changes in skin color, and mucus production. Meconium is commonly passed at this time.
The initial assessment of the neonate is performed immediately after birth as the nurse conducts a brief physical examination and assigns an Apgar score. A more comprehensive physical assessment and a gestational age assessment are completed within the first few hours of life.
The initial examination of the newborn may be accomplished while the infant is lying on the mother’s abdomen or chest, in her arms immediately after birth, or alternatively while the newborn is lying on the radiant warmer bed.
The newborn remains skin-to-skin with the mother for at least the first one to two hours after birth. Breastfeeding is initiated during that time.
The Apgar score is a routine rapid assessment of the newborn’s overall status and response to resuscitation. The five signs that indicate the physiologic state of the neonate include:
Heart rate, based on auscultation with a stethoscope or palpation of the umbilical cord
Respiratory effort, based on the observed movement of the chest wall
Muscle tone, based on the degree of flexion and movement of the extremities
Reflex irritability, based on the presence of a grimace, crying, or active withdrawal
Generalized skin color, described as pallid, cyanotic, or pink

"Apgar Score" by Dr. Vijaya chandar, used under CC BY SA 4.0/Cropped from original
0 to 3 indicate severe distress
4 to 6 indicate moderate difficulty
7 to 10 indicate that the newborn is having minimal or no difficulty adjusting to extrauterine life
Some people use the following mnemonic to remember the criteria:
A: Appearance (Color)
P: Pulse (Heart Rate)
G: Grimace (Reflex)
A: Activity (Muscle Tone)
R: Respirations (Respriatory Effort)
The score is assigned at one and five minutes after birth. For scores less than 7 at five minutes, the assessment should be repeated every five minutes for up to twenty minutes. Apgar scores do not predict future neurologic outcomes for the newborn but are useful in describing the newborn’s transition to the extrauterine environment and response to resuscitative efforts if needed. If resuscitation is required, it should be initiated before the one-minute Apgar score is determined.
Features to assess in the general survey include:
Color
Posture
Activity
Obvious signs of anomalies that can cause initial distress
Presence of bruising or other birth trauma
State of alertness
The neonate’s maturity level can be determined by assessing general appearance. The normal resting position of the term newborn is one of general flexion.

The desired range for axillary temperature is 36.5–37.5 °C (97.7–99.5 °F).
Neonatal respirations are shallow and irregular; this irregularity is called periodic breathing and is a normal finding. Respirations should be counted for a full minute. The nurse should also observe for symmetry of chest movement. The normal range for newborn respirations is 30 to 60 breaths/minute. The respiratory rate can exceed 60 breaths/minute if the newborn is very active or crying. A consistent respiratory rate greater than 60 breaths/minute can be a sign of distress and should be evaluated.
An apical pulse rate should be obtained on all newborns. Auscultation is done for a full minute, preferably when the infant is asleep or in a quiet alert state. The newborn may need to be held and comforted during the assessment.
A normal heart rate ranges from 120 to 160 beats/minute when the infant is awake.
Bradycardia is a heart rate of less than 80 beats/minute. A term newborn in deep sleep can have a heart rate in the 70s to 90s.
Tachycardia is a heart rate exceeding 180 to 200 beats/minute.
The assessment of newborn blood pressure (BP) is based on facility policy. Four extremity BPs may be assessed routinely or only when a murmur is auscultated. Normally the BP is higher in the lower extremities. If the upper extremity systolic pressures are more than 20 mmHg greater than those in the lower extremities, the infant may have a cardiac defect such as coarctation of the aorta.
Peripheral pulses are also palpated as part of the assessment in any infant with a heart murmur. If a murmur is present, oxygen saturation is usually measured using pulse oximetry.

For more inforamtion about measurements in comparison to Gestational Age, click the link below.
Baseline measurements are done and recorded to help assess progress and determine the growth patterns of the infant. These are classified as Small for Gestational age (SGA - <10%), Average for Gestational Age (AGA - 10-90%), or Large for Gestational Age (>90%). The classification is charted on a graph that compares average measurements for each gestational age.
The birth weight of a term newborn is typically in the range of 2,000 to 4,000 g (6 to 9 lb).
The head is measured at the widest part, which is the occipitofrontal diameter. The tape measure is placed around the head just above the infant’s eyebrows. The term neonate’s head circumference typically ranges from 32.5–37.5 cm (12.5–14.5 in.). The accuracy of the head circumference can be altered by temporary swelling due to pressure on the head during labor and birth or by overlapping of the cranial bones (molding).
The chest circumference is measured at the nipple line using a tape measure. It typically ranges from 30-33cm (12-13 in.).
The head-to-heel length is typically in the range of 48–53 cm (19–21 inches). Length can also change once molding subsides.

The physical examination includes a neurologic assessment of newborn reflexes. This assessment provides useful information about the newborn’s nervous system and state of neurologic maturation.
A complete list of newborn reflexes can be found in that section.
Although most newborns make the necessary biopsychosocial adjustments to extrauterine life without great difficulty, their well-being depends on the care they receive. This lesson focuses on the assessment and care of the newborn immediately after birth until discharge from the birth setting, as well as important anticipatory guidance for parents related to ongoing infant care.
With the possibility of transmission of viruses such as hepatitis B virus (HBV), hepatitis C virus, and human immunodeficiency virus (HIV) through maternal blood and blood-stained amniotic fluid, the newborn must be considered a potential contamination source until proven otherwise. As part of standard precautions, the nurse should wear gloves when handling the newborn until blood and amniotic fluid are removed by the initial bath.
Care begins immediately after birth and focuses on assessing and stabilizing the newborn’s condition. Interprofessional care is key to optimizing outcomes for newborns. When risk factors or birth events are likely to affect the well-being of the newborn, the labor and birth nurse notifies the neonatal or pediatric care team to request their attendance at the birth or may call for them once the infant is born.
Changes can occur quickly in newborns immediately after birth. Assessment must be followed by prompt implementation of appropriate care.

Four conditions are essential for maintaining an adequate oxygen supply:
A clear airway
Effective establishment of respirations
Adequate circulation, adequate perfusion, and effective cardiac function
Adequate thermoregulation
The ideal method for promoting warmth and maintaining neonatal body temperature is early skin-to-skin care (SSC). SSC in the first hour of life increases neonatal blood glucose concentrations, improves temperature stability, and improves breastfeeding initiation and duration. SSC and breastfeeding at birth can also reduce the risk for postpartum hemorrhage. Other interventions to promote warmth include drying and wrapping the newborn in warm blankets immediately after birth, keeping the head well covered, and keeping the ambient temperature of the nursery or mother’s room at 22–26° C (72–78° F).
If the newborn does not remain skin-to-skin with the mother during the first one to two hours after birth, the nurse places the thoroughly dried infant under a radiant warmer or in a warm incubator until the body temperature stabilizes. The infant’s skin temperature is used as the point of control in a warmer with a servo controlled mechanism. The control panel is usually set between 36 and 37° C (96.8 and 98.6° F) to maintain the healthy term newborn’s skin temperature at approximately 36.5–37° C (97.7–98.6° F). The thermistor probe (automatic sensor) is usually placed on the upper quadrant of the abdomen immediately below the right or left costal margin (never over a bone) and is covered with a reflector adhesive patch. The probe is designed to detect minor temperature changes resulting from external environmental factors or neonatal factors (peripheral vasoconstriction, vasodilation, or increased metabolism) before a dramatic change in core body temperature develops. The servo controller adjusts the temperature of the warmer to maintain the infant’s skin temperature within the preset range. The nurse assesses the axillary temperature of the newborn every hour (or more often as needed).
The initial bath for an uncompromised term infant should be postponed for at least six hours and until the newborn’s skin temperature is stable as indicated by two consecutive axillary temperatures at or above 36.8° C (98.2° F). Bath time should be limited to five minutes.
The primary goal of care in the first moments after birth is to assist the newborn to successfully transition to extrauterine life. The first priority is to establish effective respirations.
If the newborn is at term, has good muscle tone, and is crying or breathing, routine care is all that is required. Routine care includes:
Placing the newborn skin-to-skin on the mother’s chest or abdomen
Drying the infant with gentle rubbing to remove moisture, which helps minimize evaporative heat loss
Removing wet linens and covering the mother and baby with a warm blanket
Drying the newborn’s head and applying a cap
Wiping away nasal and oral secretions - A bulb syringe may be used if secretions appear to be blocking the airway
Starting the ongoing assessment of the neonate’s breathing, color, and activity
If the newborn is not at term, has poor muscle tone, or is not crying or breathing, they are placed immediately under a radiant warmer. Assessments and interventions are accomplished under the warmer until the infant is stable and can be safely placed skin-to-skin with the mother. Alternatively, the infant may be transported to a nursery or neonatal intensive care (NICU) setting.
The newborn should be breathing spontaneously. Their trunk and lips should be pink. A bluish discoloration of the hands and feet (acrocyanosis) is a normal finding. If the newborn is apneic or has gasping respirations, the newborn should be placed on the radiant warmer and positive pressure ventilation should be initiated. It may take a term newborn several minutes to “pink up.” Visual inspection of cyanosis is not reliable when central cyanosis persists; instead, a pulse oximeter should be applied to the newborn’s right hand. An oxygen saturation value as compared to the newborn’s age in minutes helps guide the use of supplemental oxygen immediately after birth.
The heart rate is quickly assessed by grasping the base of the cord or by auscultating the chest with a stethoscope. The nurse counts for 6 seconds and multiplies by 10 to calculate the heart rate. The neonatal heart rate should be greater than 100 beats/minute. If the newborn requires respiratory or circulatory support, the nurse and other members of the health care team (e.g., neonatologist, respiratory therapist) should follow the most recent guidelines of the Neonatal Resuscitation Program, published by the American Heart Association (AHA) and the American Academy of Pediatrics (AAP).
As soon as possible after birth, the nurse should place identically numbered bands on the newborn’s wrist and ankle, on the mother’s wrist, and in some birth settings, on the father or significant other. Identification bands should be placed prior to the newborn being separated from the mother. An electronic infant security tag or abduction system alarm should be placed on all newborns to help protect against infant abduction. Other tracking measures include footprinting the infant with ink or a scanning device within two hours of birth and taking color photographs of the infant for identification. We will discuss the prevention of infant abduction more in the next lesson.
Contemporary birthing practices are family centered. Mother-infant contact produces physiologic benefits for the neonate and the mother. SSC promotes the physiologic stability of the newborn. Maternal levels of oxytocin and prolactin rise with SSC and early breastfeeding. Rooming in after birth until discharge from the birthing facility promotes parent-infant interaction.
At birth, neonates have low vitamin K levels related to limited transplacental transfer of vitamin K and the lack of normal intestinal flora necessary for vitamin K synthesis. The establishment of normal intestinal flora begins with early feedings, and by seven days of age, healthy newborns are able to produce their own vitamin K. It is recommend that every newborn receive a single dose of phytonadione 0.5–1 mg to prevent vitamin K–dependent hemorrhagic disease of the newborn.
The injection should be delayed to allow for the infant to spend some skin-to-skin time with the parents and for the first breastfeeding.

Instilling a prophylactic agent in the eyes of all newborns to prevent ophthalmia neonatorum or neonatal conjunctivitis, which is an inflammation caused by sexually transmitted bacteria acquired during passage through the mother’s birth canal, is advised. Because an ascending infection can occur, eye prophylaxis is recommended for all newborns, including those born by cesarean section.
Erythromycin 0.5% ophthalmic ointment is the recommended prophylactic medication to prevent infection from Neisseria gonorrhoeae (see Medication Guide: Eye Prophylaxis: Erythromycin Ophthalmic Ointment, 0.5%). Without prompt treatment, this infection can lead to blindness.
Eye prophylaxis is usually administered within the first hour after birth. It may be delayed up to two hours until after the first breastfeeding so that eye contact and parent–infant attachment and bonding are facilitated.
Eye prophylaxis for every newborn is mandated by law in the majority of US states without regard to the mode of birth.
