There are limited data comparing the different approaches to heart rate assessment during neonatal resuscitation on other neonatal outcomes. In addition, specific recommendations about the training of resuscitation providers and systems of care are provided in their respective guideline Parts.9,10. Infants with unintentional hypothermia (temperature less than 36C) immediately after stabilization should be rewarmed to avoid complications associated with low body temperature (including increased mortality, brain injury, hypoglycemia, and respiratory distress). If the heart rate remains less than 60/min despite 30 seconds of adequate PPV, chest compressions should be provided. For this reason, neonatal resuscitation should begin with PPV rather than with chest compressions.2,3 Delays in initiating ventilatory support in newly born infants increase the risk of death.1, The adequacy of ventilation is measured by a rise in heart rate and, less reliably, chest expansion. Provide chest compressions if the heart rate is absent or remains <60 bpm despite adequate assisted ventilation for 30 seconds. The guidelines form the basis of the AAP/American Heart Association (AHA) Neonatal Resuscitation Program (NRP), 8th edition, which will be available in June 2021. A newly born infant in shock from blood loss may respond poorly to the initial resuscitative efforts of ventilation, chest compressions, and/or epinephrine. Newly born infants who receive prolonged PPV or advanced resuscitation (intubation, chest compressions, or epinephrine) should be maintained in or transferred to an environment where close monitoring can be provided. There is a history of acute blood loss around the time of delivery. The 2020 guidelines are organized into "knowledge chunks," grouped into discrete modules of information on specific topics or management issues.22 Each modular knowledge chunk includes a table of recommendations using standard AHA nomenclature of COR and LOE. The goal should be to achieve oxygen saturation targets shown in Figure 1.5,6, When chest compressions are indicated, it is recommended to use a 3:1 ratio of compressions to ventilation.57, Chest compressions in infants should be delivered by using two thumbs, with the fingers encircling the chest and supporting the back, and should be centered over the lower one-third of the sternum.5,6, If the infant's heart rate is less than 60 bpm after adequate ventilation and chest compressions, epinephrine at 0.01 to 0.03 mg per kg (1:10,000 solution) should be given intravenously. When chest compressions are initiated, an ECG should be used to confirm heart rate. Consequently, all newly born babies should be attended to by at least 1 person skilled and equipped to provide PPV. Hypothermia after birth is common worldwide, with a higher incidence in babies of lower gestational age and birth weight. The heart rate should be re- checked after 1 minute of giving compressions and ventilations. Monday - Friday: 7 a.m. 7 p.m. CT Therefore, identifying a rapid and reliable method to measure the newborn's heart rate is critically important during neonatal resuscitation. Circulation. Chest compressions are provided if there is a poor heart rate response to ventilation after appropriate ventilation corrective steps, which preferably include endotracheal intubation. The practice test consists of 10 multiple-choice questions that adhere to the latest ILCOR standards. It is important to continue PPV and chest compressions while preparing to deliver medications. Part 5: neonatal resuscitation: 2020 American Heart Association Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care. In preterm infants, delaying clamping reduces the need for vasopressors or transfusions. Ventilation using a flow-inflating bag, self-inflating bag, or T-piece device can be effective. If the infant's heart rate is less than 60 beats per minute after adequate positive pressure ventilation and chest compressions, intravenous epinephrine at 0.01 to 0.03 mg per kg (1:10,000 solution) is recommended. The primary objective of neonatal resuscitation is effective ventilation; an increase in heart rate indicates effective ventilation. *In this situation, intravascular means intravenous or intraosseous. Adaptive trials, comparative effectiveness designs, and those using cluster randomization may be suitable for some questions, such as the best approach for MSAF in nonvigorous infants. Title: Microsoft PowerPoint - CPS GR Final Author: JackieM Created Date: 9/10/2021 9:22:37 PM Every healthy newly born baby should have a trained and equipped person assigned to facilitate transition. CPAP, a form of respiratory support, helps newly born infants keep their lungs open. Placing healthy newborn infants who do not require resuscitation skin-to-skin after birth can be effective in improving breastfeeding, temperature control and blood glucose stability. Newly born infants who required advanced resuscitation are at significant risk of developing moderate-to-severe HIE. Supplemental oxygen should be used judiciously, guided by pulse oximetry. CPAP is helpful for preterm infants with breathing difficulty after birth or after resuscitation33 and may reduce the risk of bronchopulmonary dysplasia in very preterm infants when compared with endotracheal ventilation.3436 CPAP is also a less invasive form of respiratory support than intubation and PPV are. While the science and practices surrounding monitoring and other aspects of neonatal resuscitation continue to evolve, the development of skills and practice surrounding PPV should be emphasized. Epinephrine is indicated if the infant's heart rate continues to be less than 60 bpm after 30 seconds of adequate PPV with 100 percent oxygen and chest compressions.

You administer 10 mL/kg of normal saline (based on the newborn's estimated weight). One RCT (low certainty of evidence) suggests improved oxygenation after resuscitation in preterm babies who received repeated tactile stimulation. The studies were too heterogeneous to be amenable to meta-analysis. The chest compression technique of using two thumbs, with the fingers encircling the chest and supporting the back, achieved better results in swine models compared with the technique of using two fingers, with a second hand supporting the back. A laboring woman received a narcotic medication for pain relief 1 hour before delivery.The baby does not have spontaneous respirations and does not improve with stimulation.Your first priority is to. Intraosseous needles are reasonable, but local complications have been reported. In babies who appear to have ineffective respiratory effort after birth, tactile stimulation is reasonable. However, it may be reasonable to increase inspired oxygen to 100% if there was no response to PPV with lower concentrations. Among the most important changes are to not intervene with endotracheal suctioning in vigorous infants born through meconium-stained amniotic fluid (although endotracheal suctioning may be appropriate in nonvigorous infants); to provide positive pressure ventilation with one of three devices when necessary; to begin resuscitation of term infants using room air or blended oxygen; and to have a pulse oximeter readily available in the delivery room. It is the expert opinion of national medical societies that conditions exist for which it is reasonable to not initiate resuscitation or to discontinue resuscitation once these conditions are identified. When blood loss is suspected in a newly born infant who responds poorly to resuscitation (ventilation, chest compressions, and/or epinephrine), it may be reasonable to administer a volume expander without delay. The usefulness of positive end-expiratory pressure during PPV for term infant resuscitation has not been studied.6 A recent study showed that use of mask continuous positive airway pressure for resuscitation and treatment of respiratory distress syndrome in spontaneously breathing preterm infants reduced the need for intubation and subsequent mechanical ventilation without increasing the risk of bronchopulmonary dysplasia or death.29 In a preterm infant needing PPV, a PIP of 20 to 25 cm H2O may be adequate to increase heart rate while avoiding a higher PIP to prevent injury to preterm lungs, and positive end-expiratory pressure may be beneficial if suitable equipment is available.6. Post-resuscitation care. minutes, and 80% at 5 minutes of life. Studies of newly born animals showed that PEEP facilitates lung aeration and accumulation of functional residual capacity, prevents distal airway collapse, increases lung surface area and compliance, decreases expiratory resistance, conserves surfactant, and reduces hyaline membrane formation, alveolar collapse, and the expression of proinflammatory mediators. During resuscitation, a baby is responding to positive-pressure ventilation with a rapidly increasing heart rate. In newborns who do not require resuscitation, delaying cord clamping for more than 30 seconds reduces anemia, especially in preterm infants. Case series in preterm infants have found that most preterm infants can be resuscitated using PPV inflation pressures in the range of 20 to 25 cm H. An observational study including 1962 infants between 23 and 33 weeks gestational age reported lower rates of mortality and chronic lung disease when giving PPV with PEEP versus no PEEP. For every 30 seconds that ventilation is delayed, the risk of prolonged admission or death increases by 16%. We thank Dr. Abhrajit Ganguly for assistance in manuscript preparation. For neonatal resuscitation providers, it may be reasonable to brief before delivery and debrief after neonatal resuscitation. For infants born at less than 28 wk of gestation, cord milking is not recommended. Case series show small numbers of intact survivors after 20 minutes of no detectable heart rate. Volunteers with recognized expertise in resuscitation are nominated by the writing group chair and selected by the AHA ECC Committee. Failure to respond to epinephrine in a newborn with history or examination consistent with blood loss may require volume expansion. Hypoglycemia is common in infants who have received advanced resuscitation and is associated with poorer outcomes.8 These infants should be monitored for hypoglycemia and treated appropriately. Positive pressure ventilation should be provided at 40 to 60 inflations per minute with peak inflation pressures up to 30 cm of water in term newborns and 20 to 25 cm of water in preterm infants. Coverage of guidelines from other organizations does not imply endorsement by AFP or the AAFP. Variables to be considered may include whether the resuscitation was considered optimal, availability of advanced neonatal care (such as therapeutic hypothermia), specific circumstances before delivery, and wishes expressed by the family.3,6, Some babies are so sick or immature at birth that survival is unlikely, even if neonatal resuscitation and intensive care are provided. The heart rate should be re-checked after 1 minute of giving compressions and ventilations. Newly born infants who receive prolonged PPV or advanced resuscitation (eg, intubation, chest compressions epinephrine) should be closely monitored after stabilization in a neonatal intensive care unit or a monitored triage area because these infants are at risk for further deterioration. Important aspects of neonatal resuscitation are the hospital policy and planning that ensure necessary equipment and personnel are present before delivery.1 Anticipation and preparation are essential elements for successful resuscitation,18 and this requires timely and accurate communication between the obstetric team and the neonatal resuscitation team. High-quality observational studies of large populations may also add to the evidence. . Routine suctioning, whether oral, nasal, oropharyngeal, or endotracheal, is not recommended because of a lack of benefit and risk of bradycardia. The ILCOR task force review, when comparing PPV with sustained inflation breaths, defined PPV to have an inspiratory time of 1 second or less, based on expert opinion. While there has been research to study the potential effectiveness of providing longer, sustained inflations, there may be potential harm in providing sustained inflations greater than 10 seconds for preterm newborns. Premature animals exposed to brief high tidal volume ventilation (from high PIP) develop lung injury, impaired gas exchange, and decreased lung compliance. 1-800-AHA-USA-1 Early skin-to-skin contact benefits healthy newborns who do not require resuscitation by promoting breastfeeding and temperature stability. On the other hand, overestimation of heart rate when a newborn is bradycardic may delay necessary interventions. Short, frequent practice (booster training) has been shown to improve neonatal resuscitation outcomes.5 Educational programs and perinatal facilities should develop strategies to ensure that individual and team training is frequent enough to sustain knowledge and skills. Although this flush volume may . The 7th edition of the Textbook of Neonatal Resuscitation recommends 0.5-mL to 1-mL flush following IV epinephrine (0.01 to 0.03 mg/kg dose) via a low-lying UVC [6]. A meta-analysis of 5 randomized and quasirandomized trials enrolling term and late preterm newborns showed no difference in rates of hypoxic-ischemic encephalopathy (HIE). If the heart rate remains below 60 beats per minute despite 30 seconds of adequate positive pressure ventilation, chest compressions should be initiated with a two-thumb encircling technique at a 3:1 compression-to-ventilation ratio.
