Abstract: The Apgar score provides an accustomed and convenient method for reporting the status of the newborn infant immediately after nascency and the response to resuscitation if needed. The Apgar score lone cannot exist considered to exist evidence of or a consequence of asphyxia, does non predict private neonatal mortality or neurologic outcome, and should not be used for that purpose. An Apgar score assigned during a resuscitation is not equivalent to a score assigned to a spontaneously breathing infant. The American University of Pediatrics and the American College of Obstetricians and Gynecologists encourage utilize of an expanded Apgar score reporting course that accounts for concurrent resuscitative interventions.

Introduction

In 1952, Dr. Virginia Apgar devised a scoring system that was a rapid method of assessing the clinical status of the newborn baby at ane minute of historic period and the demand for prompt intervention to establish breathing 1. A second report evaluating a larger number of patients was published in 1958 2. This scoring system provided a standardized assessment for infants after delivery. The Apgar score comprises five components: 1) color, 2) eye charge per unit, 3) reflexes, iv) muscle tone, and 5) respiration, each of which is given a score of 0, 1, or 2. Thus, the Apgar score quantitates clinical signs of neonatal depression such every bit cyanosis or pallor, bradycardia, depressed reflex response to stimulation, hypotonia, and apnea or gasping respirations. The score is reported at 1 minute and 5 minutes after nascency for all infants, and at 5-minute intervals thereafter until xx minutes for infants with a score less than vii 3. The Apgar score provides an accepted and convenient method for reporting the status of the newborn baby immediately after birth and the response to resuscitation if needed; nevertheless, information technology has been inappropriately used to predict individual adverse neurologic outcome. The purpose of this statement is to place the Apgar score in its proper perspective. This statement revises the 2006 College Committee Opinion and AAP Policy Statement to include updated guidance from Neonatal Encephalopathy and Neurologic Outcome, Second Edition, along with new guidance on neonatal resuscitation.

The Neonatal Resuscitation Programme guidelines state that the Apgar score is

useful for carrying information about the newborn's overall condition and response to resuscitation. However, resuscitation must be initiated before the one-infinitesimal score is assigned. Therefore, the Apgar score is not used to determine the need for initial resuscitation, what resuscitation steps are necessary, or when to use them 3.

An Apgar score that remains 0 beyond 10 minutes of historic period may, withal, be useful in determining whether continued resuscitative efforts are indicated considering very few infants with an Apgar score of 0 at x minutes have been reported to survive with a normal neurologic outcome 3 iv 5. In line with this, the 2011 Neonatal Resuscitation Program guidelines country that "if you can confirm that no heart rate has been detectable for at to the lowest degree 10 minutes, discontinuation of resuscitative efforts may be advisable" iii.

Neonatal Encephalopathy and Neurologic Upshot, Second Edition, published in 2014 by the Higher in collaboration with the AAP, defines a v-minute Apgar score of seven–x equally reassuring, a score of 4–6 as moderately abnormal, and a score of 0–3 as low in the term baby and late-preterm infant 6. That document considers an Apgar score of 0–iii at 5 minutes or more equally a nonspecific sign of illness, which "may exist one of the first indications of encephalopathy" 6. Notwithstanding, a persistently low Apgar score lone is not a specific indicator for intrapartum compromise. Further, although the score is used widely in outcome studies, its inappropriate utilise has led to an erroneous definition of asphyxia. Asphyxia is defined as the marked harm of gas exchange leading, if prolonged, to progressive hypoxemia, hypercapnia, and significant metabolic acidosis. The term asphyxia, which describes a process of varying severity and duration rather than an stop point, should non exist practical to birth events unless specific testify of markedly dumb intrapartum or immediate postnatal gas exchange can be documented based on laboratory testing half dozen.

Limitations of the Apgar Score

Information technology is important to recognize the limitations of the Apgar score. The Apgar score is an expression of the baby's physiologic condition at one point in time, which includes subjective components. At that place are numerous factors that tin influence the Apgar score, including maternal sedation or anesthesia, congenital malformations, gestational age, trauma, and interobserver variability half-dozen. In addition, the biochemical disturbance must exist significant before the score is afflicted. Elements of the score such as tone, color, and reflex irritability can be subjective, and partially depend on the physiologic maturity of the infant. The score likewise may exist affected past variations in normal transition. For case, lower initial oxygen saturations in the starting time few minutes demand not prompt immediate supplemental oxygen administration; the Neonatal Resuscitation Program targets for oxygen saturation are 60–65% at one minute and 80–85% at 5 minutes 3. The healthy preterm infant with no bear witness of asphyxia may receive a depression score only considering of immaturity vii 8. The incidence of low Apgar scores is inversely related to nascence weight, and a low score cannot predict morbidity or mortality for any individual infant eight ix. As previously stated, it also is inappropriate to use an Apgar score alone to diagnose asphyxia.

Apgar Score and Resuscitation

The 5-infinitesimal Apgar score, and particularly a modify in the score betwixt ane infinitesimal and 5 minutes, is a useful index of the response to resuscitation. If the Apgar score is less than 7 at v minutes, the Neonatal Resuscitation Program guidelines land that the assessment should be repeated every five minutes for upward to 20 minutes 3. All the same, an Apgar score assigned during a resuscitation is non equivalent to a score assigned to a spontaneously breathing infant 10. There is no accepted standard for reporting an Apgar score in infants undergoing resuscitation later birth because many of the elements contributing to the score are altered past resuscitation. The concept of an assisted score that accounts for resuscitative interventions has been suggested, merely the predictive reliability has not been studied. In order to correctly describe such infants and provide accurate documentation and data collection, an expanded Apgar score report form is encouraged Figure 1. This expanded Apgar score also may prove to be useful in the setting of delayed string clamping, where the time of nascency (complete delivery of the infant), the time of cord clamping, and the time of initiation of resuscitation all can exist recorded in the comments box.

The Apgar score alone cannot be considered to be evidence of or a consequence of asphyxia. Many other factors, including nonreassuring fetal eye charge per unit monitoring patterns and abnormalities in umbilical arterial blood gases, clinical cerebral function, neuroimaging studies, neonatal electroencephalography, placental pathology, hematologic studies, and multisystem organ dysfunction need to be considered in diagnosing an intrapartum hypoxic–ischemic event five. When a Category I (normal) or Category II (indeterminate) fetal center rate tracing is associated with Apgar scores of 7 or college at 5 minutes, a normal umbilical cord arterial blood pH (± 1 standard divergence), or both, it is not consistent with an astute hypoxic–ischemic effect 6.

Prediction of Outcome

A one-minute Apgar score of 0–3 does not predict any individual infant'southward upshot. A 5-minute Apgar score of 0–iii correlates with neonatal mortality in large populations 11 12, but does not predict individual futurity neurologic dysfunction. Population studies have uniformly reassured united states of america that most infants with low Apgar scores will not develop cognitive palsy. However, a depression five-minute Apgar score clearly confers an increased relative gamble of cerebral palsy, reported to exist as high as xx-fold to 100-fold over that of infants with a 5-minute Apgar score of 7–10 9 xiii 14 15. Although private take chances varies, the population take a chance of poor neurologic outcomes besides increases when the Apgar score is 3 or less at 10 minutes, 15 minutes, and 20 minutes 16. When a newborn has an Apgar score of v or less at 5 minutes, umbilical artery blood gas from a clamped section of the umbilical string should be obtained, if possible 17. Submitting the placenta for pathologic examination may be valuable.

Other Applications

Monitoring of depression Apgar scores from a delivery service can be useful. Individual instance reviews can identify needs for focused educational programs and improvement in systems of perinatal intendance. Analyzing trends allows for the assessment of the effect of quality improvement interventions.

Conclusions

The Apgar score describes the condition of the newborn baby immediately later on birth and, when properly applied, is a tool for standardized cess 18. It also provides a mechanism to record fetal-to-neonatal transition. Apgar scores exercise non predict private mortality or agin neurologic outcome. However, based on population studies, Apgar scores of less than 5 at v minutes and 10 minutes clearly confer an increased relative gamble of cerebral palsy, and the caste of abnormality correlates with the risk of cerebral palsy. Nigh infants with depression Apgar scores, yet, volition not develop cognitive palsy. The Apgar score is affected by many factors, including gestational age, maternal medications, resuscitation, and cardiorespiratory and neurologic conditions. If the Apgar score at 5 minutes is vii or greater, it is unlikely that peripartum hypoxia–ischemia caused neonatal encephalopathy.

Recommendations

• The Apgar score does not predict individual neonatal mortality or neurologic outcome, and should not exist used for that purpose.

• It is inappropriate to use the Apgar score alone to establish the diagnosis of asphyxia. The term asphyxia, which describes a process of varying severity and duration rather than an end betoken, should not exist applied to birth events unless specific evidence of markedly impaired intrapartum or immediate postnatal gas substitution can be tin be documented.

• When a newborn has an Apgar score of 5 or less at five minutes, umbilical avenue blood gas from a clamped department of umbilical cord should be obtained. Submitting the placenta for pathologic examination may be valuable.

• Perinatal health care professionals should be consequent in assigning an Apgar score during resuscitation; therefore, the American Academy of Pediatrics (AAP) and the American Higher of Obstetricians and Gynecologists (the College) encourage use of an expanded Apgar score reporting form that accounts for concurrent resuscitative interventions.
