To perform neonatal resuscitation effectively, individual providers and teams need training in the required knowledge, skills, and behaviors. Nearly 10 percent of the more than 4 million infants born in the United States annually need some assistance to begin breathing at birth, with approximately 1 percent needing extensive resuscitation1,2 and about 0.2 to 0.3 percent developing moderate or severe hypoxic-ischemic encephalopathy.3 Mortality in infants with hypoxic-ischemic encephalopathy ranges from 6 to 30 percent, and significant morbidity, such as cerebral palsy and long-term disabilities, occurs in 20 to 30 percent of survivors.4 The Neonatal Resuscitation Program (NRP), which was initiated in 1987 to identify infants at risk of respiratory depression and provide high-quality resuscitation, underwent major updates in 2006 and 2010.1,57, A 1987 study showed that nearly 78 percent of Canadian hospitals did not have a neonatal resuscitation team, and physicians were called into a significant number of community hospitals (69 percent) for neonatal resuscitation because they were not in-house.8 National guidelines in the United States and Canada recommend that a team or persons trained in neonatal resuscitation be promptly available for every birth.9,10 Actual institutional compliance with this guideline is unknown. If the baby is apneic or has a heart rate less than 100 bpm Begin the initial steps Warm, dry and stimulate for 30 seconds In one RCT and one observational study, there were no reports of technical difficulties with ECG monitoring during neonatal resuscitation, supporting its feasibility as a tool for monitoring heart rate during neonatal resuscitation. Copyright 2023 American Academy of Family Physicians. Intravenous epinephrine is preferred because. Appropriate resuscitation must be available for each of the more than 4 million infants born annually in the United States. This guideline is designed for North American healthcare providers who are looking for an up-to-date summary for clinical care, as well as for those who are seeking more in-depth information on resuscitation science and gaps in current knowledge. Hypothermia after birth is common worldwide, with a higher incidence in babies of lower gestational age and birth weight. We thank Dr. Abhrajit Ganguly for assistance in manuscript preparation. Use of ECG for heart rate detection does not replace the need for pulse oximetry to evaluate oxygen saturation or the need for supplemental oxygen. Birth 1 minute If HR remains <60 bpm, Consider hypovolemia. 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. The effect of briefing and debriefing on longer-term and critical outcomes remains uncertain. Suctioning may be considered if PPV is required and the airway appears obstructed. 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. For newly born infants who are unintentionally hypothermic (temperature less than 36C) after resuscitation, it may be reasonable to rewarm either rapidly (0.5C/h) or slowly (less than 0.5C/h). In a retrospective review, early hypoglycemia was a risk factor for brain injury in infants with acidemia requiring resuscitation. However, it may be reasonable to increase inspired oxygen to 100% if there was no response to PPV with lower concentrations. Establishing ventilation is the most important step to correct low heart rate. Oximetry is used to target the natural range of oxygen saturation levels that occur in term babies. Positive-pressure ventilation should be started in newborns who are gasping, apneic, or with a heart rate below 100 beats per minute by 60 seconds of life. ECG provides the most rapid and accurate measurement of the newborns heart rate at birth and during resuscitation. Expert neonatal and bioethical committees have agreed that, in certain clinical conditions, it is reasonable not to initiate or to discontinue life-sustaining efforts while continuing to provide supportive care for babies and families.1,2,4, If the heart rate remains undetectable and all steps of resuscitation have been completed, it may be reasonable to redirect goals of care. Multiple clinical and simulation studies examining briefings or debriefings of resuscitation team performance have shown improved knowledge or skills.812. The very limited observational evidence in human infants does not demonstrate greater efficacy of endotracheal or intravenous epinephrine; however, most babies received at least 1 intravenous dose before ROSC. A team or persons trained in neonatal resuscitation should be promptly available at all deliveries to provide complete resuscitation, including endotracheal intubation and administration of medications. If resuscitation is required, heart rate should be monitored by electrocardiography as early as possible. A rise in heart rate is the most important indicator of effective ventilation and response to resuscitative interventions. Intraosseous needles are reasonable, but local complications have been reported. If heart rate after birth remains at less than 60/min despite adequate ventilation for at least 30 s, initiating chest compressions is reasonable. 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. There is a reduction of mortality and no evidence of harm in term infants resuscitated with 21 percent compared with 100 percent oxygen. In addition, specific recommendations about the training of resuscitation providers and systems of care are provided in their respective guideline Parts.9,10. RCTs and observational studies of warming adjuncts, alone and in combination, demonstrate reduced rates of hypothermia in very preterm and very low-birth-weight babies. Peer reviewer feedback was provided for guidelines in draft format and again in final format. For term infants who do not require resuscitation at birth, it may be reasonable to delay cord clamping for longer than 30 seconds. The Neonatal Resuscitation Algorithm remains unchanged from 2015 and is the organizing framework for major concepts that reflect the needs of the baby, the family, and the surrounding team of perinatal caregivers. In newborns who do not require resuscitation, delaying cord clamping for more than 30 seconds reduces anemia, especially in preterm infants. In term infants, delaying clamping increases hematocrit and iron levels without increasing rates of phototherapy for hyperbilirubinemia, neonatal intensive care, or mortality. A large observational study found that delaying PPV increases risk of death and prolonged hospitalization. IV epinephrine every 3-5 minutes. Hypothermia at birth is associated with increased mortality in preterm infants. In the resuscitation of an infant, initial oxygen concentration of 21 percent is recommended. 1 minuteb. When anticipating a high-risk birth, a preresuscitation team briefing should be completed to identify potential interventions and assign roles and responsibilities. Although current guidelines recommend using 100% oxygen while providing chest compressions, no studies have confirmed a benefit of using 100% oxygen compared to any other oxygen concentration, including air (21%). Medications are rarely needed in resuscitation of the newly born infant because low heart rate usually results from a very low oxygen level in the fetus or inadequate lung inflation after birth. The primary goal of neonatal care at birth is to facilitate transition. Naloxone and sodium bicarbonate are rarely needed and are not recommended during neonatal resuscitation. Clinical assessment of heart rate by auscultation or palpation may be unreliable and inaccurate.14 Compared to ECG, pulse oximetry is both slower in detecting the heart rate and tends to be inaccurate during the first few minutes after birth.5,6,1012 Underestimation of heart rate can lead to potentially unnecessary interventions. If the heart rate has not increased to 60/ min or more after optimizing ventilation and chest compressions, it may be reasonable to administer intravascular* epinephrine (0.01 to 0.03 mg/kg). Other recommendations include confirming endotracheal tube placement using an exhaled carbon dioxide detector; using less than 100 percent oxygen and adequate thermal support to resuscitate preterm infants; and using therapeutic hypothermia for infants born at 36 weeks' gestation or later with moderate to severe hypoxic-ischemic encephalopathy. 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. A person viewing it online may make one printout of the material and may use that printout only for his or her personal, non-commercial reference. Intra-arterial epinephrine is not recommended. Stimulation may be provided to facilitate respiratory effort. One moderate quality RCT found higher rates of hyperthermia with exothermic mattresses. As mortality and severe morbidities decline with biomedical advancements and improvements in healthcare delivery, there is decreased ability to have adequate power for some clinical questions using traditional individual patient randomized trials. On the basis of animal research, the progression from primary apnea to secondary apnea in newborns results in the cessation of respiratory activity before the onset of cardiac failure.4 This cycle of events differs from that of asphyxiated adults, who experience concurrent respiratory and cardiac failure. Breathing: Assist breathing with PPV if baby apneic, gasping, or bradycardic. When attempts at endotracheal intubation are unsuccessful, laryngeal mask airway (size 1) is an alternative for providing PPV in infants weighing more than 2 kg or in infants greater than 34 weeks' gestation.5,6,26, Neonatal resuscitation aims to restore tissue oxygen delivery before irreversible damage occurs. 1. For nonvigorous newborns (presenting with apnea or ineffective breathing effort) delivered through MSAF, routine laryngoscopy with or without tracheal suctioning is not recommended. No studies have examined PEEP vs. no PEEP when positive pressure ventilation is used after birth. Ventilation should be optimized before starting chest compressions, possibly including endotracheal intubation. Exhaled carbon dioxide detectors can be used to confirm endotracheal tube placement in an infant. 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. The airway is cleared (if necessary), and the infant is dried. After 30 seconds, Rescuer 2 evaluates heart rate. 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. doi: 10.1161/ CIR.0000000000000902. Heart rate is assessed initially by auscultation and/or palpation. Excessive peak inflation pressures are potentially harmful and should be avoided. ECG (3-lead) displays a reliable heart rate faster than pulse oximetry. What is true about a pneumothorax in the newborn? You administer 10 mL/kg of normal saline (based on the newborn's estimated weight). One large retrospective review found that 0.04% of newborns received volume resuscitation in the delivery room, confirming that it is a relatively uncommon event. Randomized controlled studies and observational studies in settings where therapeutic hypothermia is available (with very low certainty of evidence) describe variable rates of survival without moderate-to-severe disability in babies who achieve ROSC after 10 minutes or more despite continued resuscitation. Consequently, all newly born babies should be attended to by at least 1 person skilled and equipped to provide PPV. 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. Epinephrine (adrenaline) is the only medication recommended by the International Liaison Committee On Resuscitation (ILCOR) during resuscitation in newborns with persistent bradycardia or . Internal validity might be better addressed by clearly defined primary outcomes, appropriate sample sizes, relevant and timed interventions and controls, and time series analyses in implementation studies. If a birth is at the lower limit of viability or involves a condition likely to result in early death or severe morbidity, noninitiation or limitation of neonatal resuscitation is reasonable after expert consultation and parental involvement in decision-making. Every birth should be attended by at least 1 person who can perform the initial steps of newborn resuscitation and initiate PPV, and whose only responsibility is the care of the newborn. The American Heart Association is a qualified 501(c)(3) tax-exempt organization. Once the infant is brought to the warmer, the head is kept in the sniffing position to open the airway. If the infant needs PPV, the recommended approach is to monitor the inflation pressure and to initiate PPV using a peak inspiratory pressure (PIP) of 20 cm H2O for the first few breaths; however, a PIP of 30 to 40 cm H2O (in some term infants) may be required at a rate of 40 to 60 breaths per minute.5,6 The best measure of adequate ventilation is prompt improvement in heart rate.24 Auscultation of the precordium is the primary means of assessing heart rate, but for infants requiring respiratory support, pulse oximetry is recommended.5,6 However, if the heart rate does not increase with mask PPV and there is no chest rise, ventilation should be optimized by implementing the following six steps: (1) adjust the mask to ensure a good seal; (2) reposition the airway by adjusting the position of the head; (3) suction the secretions in the mouth and nose; (4) open the mouth slightly and move the jaw forward; (5) increase the PIP enough to move the chest; and (6) consider an alternate airway (endotracheal intubation or laryngeal mask airway).5 PIP may be decreased when the heart rate increases to more than 60 bpm, and PPV may be discontinued once the heart rate is more than 100 bpm and there is spontaneous breathing. Finally, we wish to reinforce the importance of addressing the values and preferences of our key stakeholders, the families and teams who are involved in the process of resuscitation. It may be reasonable to use higher concentrations of oxygen during chest compressions. Epinephrine is indicated if the heart rate remains below 60 beats per minute despite 60 seconds of chest compressions and adequate ventilation. Newly born infants who required advanced resuscitation are at significant risk of developing moderate-to-severe HIE. Neonatal resuscitation program Your team is resuscitating a newborn whose heart rate remains less than 60 bpm despite effective PPV and 60 seconds of chest compressions. CPAP, a form of respiratory support, helps newly born infants keep their lungs open. For every 30 seconds that ventilation is delayed, the risk of prolonged admission or death increases by 16%. There were only minor changes to the NRP algorithm and recommended practices. Chest compressions should be started if the heart rate remains less than 60/min after at least 30 seconds of adequate PPV.1, Oxygen is essential for organ function; however, excess inspired oxygen during resuscitation may be harmful. 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. In newly born infants who are gasping or apneic within 60 s after birth or who are persistently bradycardic (heart rate less than 100/min) despite appropriate initial actions (including tactile stimulation), PPV should be provided without delay. Rapid and effective response and performance are critical to good newborn outcomes. In newly born babies receiving resuscitation, if there is no heart rate and all the steps of resuscitation have been performed, cessation of resuscitation efforts should be discussed with the team and the family. In newly born infants who require PPV, it is reasonable to use peak inflation pressure to inflate the lung and achieve a rise in heart rate. Dallas, TX 75231, Customer Service However, if heart rate remains less than 60/min after ventilating with 100% oxygen (preferably through an endotracheal tube) and chest compressions, administration of epinephrine is indicated. Check the heart rate by counting the beats in 6 seconds and multiply by 10. 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. Early cord clamping (within 30 seconds) may interfere with healthy transition because it leaves fetal blood in the placenta rather than filling the newborns circulating volume. Unauthorized use prohibited. 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. In a meta-analysis of 8 RCTs involving 1344 term and late preterm infants with moderate-to-severe encephalopathy and evidence of intrapartum asphyxia, therapeutic hypothermia resulted in a significant reduction in the combined outcome of mortality or major neurodevelopmental disability to 18 months of age (odds ratio 0.75; 95% CI, 0.680.83). The International Liaison Committee on Resuscitation (ILCOR) Formula for Survival emphasizes 3 essential components for good resuscitation outcomes: guidelines based on sound resuscitation science, effective education of resuscitation providers, and implementation of effective and timely resuscitation.8 The 2020 neonatal guidelines contain recommendations, based on the best available resuscitation science, for the most impactful steps to perform in the birthing room and in the neonatal period. A randomized study showed similar success in providing effective ventilation using either laryngeal mask airway or endotracheal tube. In animal studies (very low quality), the use of alterative compression-to-inflation ratios to 3:1 (eg, 2:1, 4:1, 5:1, 9:3, 15:2, and continuous chest compressions with asynchronous PPV) are associated with similar times to ROSC and mortality rates. In this review, we provide the current recommendations for use of epinephrine during neonatal . One RCT (low certainty of evidence) suggests improved oxygenation after resuscitation in preterm babies who received repeated tactile stimulation. Other important goals include establishment and maintenance of cardiovascular and temperature stability as well as the promotion of mother-infant bonding and breast feeding, recognizing that healthy babies transition naturally. 2020;142(suppl 2):S524S550. 5 As soon as the infant is delivered, a timer or clock is started. PPV may be initiated with air (21% oxygen) in term and late preterm babies, and up to 30% oxygen in preterm babies. Babies who are breathing well and/or crying are cared for skin-to-skin with their mothers and should not need interventions such as routine tactile stimulation or suctioning, even if the amniotic fluid is meconium stained.7,19 Avoiding unnecessary suctioning helps prevent the risk of induced bradycardia as a result of suctioning of the airway. The inability of newly born infants to establish and sustain adequate or spontaneous respiration contributes significantly to these early deaths and to the burden of adverse neurodevelopmental outcome among survivors. A multicenter, case-control study identified 10 perinatal risk factors that predict the need for advanced neonatal resuscitation. With secondary apnea, the heart rate continues to drop, and blood pressure decreases as well. The neonatal epinephrine dose is 0.01 to 0.03 mg per kg (1:10,000 solution) given intravenously (via umbilical venous catheter).1,2,5,6 If there is any delay in securing venous access, epinephrine can be given via endotracheal tube at a higher dose of 0.05 to 0.10 mg per kg (1:10,000 solution), followed by intravenous dosing, if necessary, as soon as access is established.5, Naloxone is not recommended during neonatal resuscitation in the delivery room; infants with respiratory depression should be resuscitated with PPV.1,2,5,6 Volume expansion (using crystalloid or red blood cells) is recommended when blood loss is suspected (e.g., pale skin, poor perfusion, weak pulse) and when the infant's heart rate continues to be low despite effective resuscitation.5,6 Sodium bicarbonate is not recommended during neonatal resuscitation in the delivery room, because it does not improve survival or neurologic outcome.6,39, Approximately 7 to 20 percent of deliveries are complicated by meconium-stained amniotic fluid; these infants have a 2 to 9 percent risk of developing meconium aspiration syndrome.50 Oral and nasopharyngeal suction on the perineum is not recommended, because it has not been shown to reduce the risk of meconium aspiration syndrome.20 In the absence of randomized controlled trials, there is insufficient evidence to recommend changing the current practice of intubation and endotracheal suction in nonvigorous infants (as defined by decreased heart rate, respiratory effort, or muscle tone) born through meconium-stained amniotic fluid.1,2,5 However, if attempted intubation is prolonged or unsuccessful, and bradycardia is present, bag and mask ventilation is advised.5,6 Endotracheal suctioning of vigorous infants is not recommended.1,2,5,6, Withholding resuscitation and offering comfort care is appropriate (with parental consent) in certain infants, such as very premature infants (born at less than 23 weeks' gestation or weighing less than 400 g) and infants with anencephaly or trisomy 13 syndrome.5 If there is no detectable heart rate after 10 minutes of resuscitation, it is appropriate to consider discontinuing resuscitation.5,6, Intravenous glucose infusion should be started soon after resuscitation to avoid hypoglycemia.5,6 In addition, infants born at 36 weeks' gestation or later with evolving moderate to severe hypoxic-ischemic encephalopathy should be offered therapeutic hypothermia, using studied protocols, within six hours at a facility with capabilities of multidisciplinary care and long-term follow-up.57. All Rights Reserved. This guideline affirms the previous recommendations. There is no evidence from randomized trials to support the use of volume resuscitation at delivery. In term and preterm newly born infants, it is reasonable to initiate PPV with an inspiratory time of 1 second or less. The suggested ratio is 3 chest compressions synchronized to 1 inflation (with 30 inflations per minute and 90 compressions per minute) using the 2 thumbencircling hands technique for chest compressions.
