Preterm infants less than 32 weeks' gestation are more likely to develop hyperoxemia with the initial use of 100 percent oxygen, and develop hypoxemia with 21 percent oxygen compared with an initial concentration of 30 or 90 percent oxygen. 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. Neonatal resuscitation science has advanced significantly over the past 3 decades, with contributions by many researchers in laboratories, in the delivery room, and in other clinical settings. This guideline affirms the previous recommendations. Compared with preterm infants receiving early cord clamping, those receiving delayed cord clamping were less likely to receive medications for hypotension in a meta-analysis of 6 RCTs. Consider pneumothorax. This content is owned by the AAFP. A meta-analysis of 3 RCTs (low certainty of evidence) and a further single RCT suggest that nonvigorous newborns delivered through MSAF have the same outcomes (survival, need for respiratory support, or neurodevelopment) whether they are suctioned before or after the initiation of PPV. Exhaled carbon dioxide detectors to confirm endotracheal tube placement. Team training remains an important aspect of neonatal resuscitation, including anticipation, preparation, briefing, and debriefing. Author disclosure: No relevant financial affiliations. The following knowledge gaps require further research: For all these gaps, it is important that we have information on outcomes considered critical or important by both healthcare providers and families of newborn infants. Most newly born infants do not require immediate cord clamping or resuscitation and can be evaluated and monitored during skin-to-skin contact with their mothers after birth. 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. One observational study in newly born infants associated high tidal volumes during resuscitation with brain injury. 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. 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). For neonatal resuscitation providers, it may be reasonable to brief before delivery and debrief after neonatal resuscitation. Part 2: Evidence Evaluation and Guidelines Development, Part 3: Adult Basic and Advanced Life Support, Part 4: Pediatric Basic and Advanced Life Support, Part 9: COVID-19 Interim Guidance for Healthcare Providers, Part 10: COVID-19 Interim Guidance for EMS, 2020 American Heart Association Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care. Every birth should be attended by one person who is assigned, trained, and equipped to initiate resuscitation and deliver positive pressure ventilation. The airway is cleared (if necessary), and the infant is dried. If you have a certificate code, then you can manually verify a certificate by entering the code here. It is important to recognize that there are several significant gaps in knowledge relating to neonatal resuscitation. Ninety percent of infants transition safely, and it is up to the physician to assess risk factors, identify the nearly 10 percent of infants who need resuscitation, and respond appropriately. If the infant's heart rate is less than 100 beats per minute and/or the infant has apnea or gasping respiration, positive pressure ventilation via face mask should be initiated with 21 percent oxygen (room air) or blended oxygen using a self-inflating bag, flow-inflating bag, or T-piece device while monitoring the inflation pressure. While vascular access is being obtained, it may be reasonable to administer endotracheal epinephrine at a larger dose (0.05 to 0.1 mg/kg). monitored. Several animal studies found that ventilation with high volumes caused lung injury, impaired gas exchange, and reduced lung compliance in immature animals. Routine oral, nasal, oropharyngeal, or endotracheal suctioning of newly born babies is not recommended. The research community needs to address the paucity of educational studies that provide outcomes with a high level of certainty. Supplemental oxygen should be used judiciously, guided by pulse oximetry. 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. For every 30 seconds that ventilation is delayed, the risk of prolonged admission or death increases by 16%. If there is ineffective breathing effort or apnea after birth, tactile stimulation may stimulate breathing. Therapeutic hypothermia is recommended in infants born at 36 weeks' gestation or later with evolving moderate to severe hypoxic-ischemic encephalopathy. Neonatal resuscitation teams may therefore benefit from ongoing booster training, briefing, and debriefing. Chest compressions are provided if there is a poor heart rate response to ventilation after appropriate ventilation corrective steps, which preferably include endotracheal intubation. Before appointment, all peer reviewers were required to disclose relationships with industry and any other potential conflicts of interest, and all disclosures were reviewed by AHA staff. One observational study describes the initial pattern of breathing in term and preterm newly born infants to have an inspiratory time of around 0.3 seconds. It may be reasonable to use higher concentrations of oxygen during chest compressions. Most RCTs in well-resourced settings would routinely manage at-risk babies under a radiant warmer. Suctioning may be considered for suspected airway obstruction. Hypothermia at birth is associated with increased mortality in preterm infants. Wrapping, in addition to radiant heat, improves admission temperature of preterm infants. If there is a heart rate response: Continue uninterrupted ventilation until the infant begins to breathe adequately and the heart rate is above 100 min-1. 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. Compresses correctly: Rate is correct. 5 minutec. Circulation. Electrocardiography detects the heart rate faster and more accurately than a pulse oximeter. These guidelines apply primarily to the newly born baby who is transitioning from the fluid-filled womb to the air-filled room. Successful neonatal resuscitation efforts depend on critical actions that must occur in rapid succession to maximize the chances of survival. Once the infant is brought to the warmer, the head is kept in the sniffing position to open the airway. Evaluate respirations The three signs of effective resuscitation are: Heart rate Respirations Assessment of oxygenation (O2 Sat based on age in minutes) Baby can take up to ten minutes to reach an oxygen saturation of 90-95%. Current resuscitation guidelines recommend that epinephrine should be used if the newborn remains bradycardic with heart rate <60 bpm after 30 s of what appears to be effective ventilation with chest rise, followed by 30 s of coordinated chest compressions and ventilations (1, 8, 9). 2020;142(suppl 2):S524S550. Positive-Pressure Ventilation (PPV) Before every birth, a standardized risk factors assessment tool should be used to assess perinatal risk and assemble a qualified team on the basis of that risk. Although this flush volume may . A newly born infant in shock from blood loss may respond poorly to the initial resuscitative efforts of ventilation, chest compressions, and/or epinephrine. The exhaled carbon dioxide detector changes from purple to yellow with endotracheal intubation, and a negative result suggests esophageal intubation.5,6,25 Clinical indicators of endotracheal intubation, such as condensation in the tube, chest wall movement, or presence of bilateral equal breath sounds, have not been well studied. If the heart rate remains less than 60/min despite these interventions, chest compressions can supply oxygenated blood to the brain until the heart rate rises. "Epinephrine is indicated when the heart rate remains below 60 beats per minute after you have given 30 seconds of effective assisted ventilation (preferably after endotracheal intubation) and at least another 45 to 60 seconds of coordinated chest compressions and effective ventilation." (p 219) In this review, we provide the current recommendations for use of epinephrine during neonatal . High-quality observational studies of large populations may also add to the evidence. The effect of briefing and debriefing on longer-term and critical outcomes remains uncertain. Identification of risk factors for resuscitation may indicate the need for additional personnel and equipment. Exothermic mattresses may be effective in preventing hypothermia in preterm babies. ** After completing the initial steps of providing warmth, positioning the infant in the sniffing position, clearing the airway and evaluate the infant's response with the following: If the baby is bradycardic (HR <60 per minute) after 90 seconds of resuscitation with a lower concentration of oxygen, oxygen concentration should be increased to 100% until recovery of a normal heart rate (Class IIb, LOE B). Excessive chest wall movement should be avoided.2,6, In spontaneously breathing preterm infants with respiratory distress, either CPAP or endotracheal intubation with mechanical ventilation may be used.1,5,6, In preterm infants less than 32 weeks' gestation, an initial oxygen concentration of more than 21 percent (30 to 40 percent), but less than 100 percent should be used. The recommended route is intravenous, with the intraosseous route being an alternative. Delayed umbilical cord clamping was recommended for both term and preterm neonates in 2015. One RCT (low certainty of evidence) suggests improved oxygenation after resuscitation in preterm babies who received repeated tactile stimulation. For term and preterm infants who require resuscitation at birth, there is insufficient evidence to recommend early cord clamping versus delayed cord clamping. It is important to continue PPV and chest compressions while preparing to deliver medications. In addition, accurate, fast, and continuous heart rate assessment is necessary for newborns in whom chest compressions are initiated. However, free radicals are generated when successful resuscitation results in reperfusion and restoration of oxygen delivery to organs.44 Use of 100 percent oxygen may increase the load of oxygen free radicals, which can potentially lead to end-organ damage. ECG provides the most rapid and accurate measurement of the newborns heart rate at birth and during resuscitation. 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. Available for purchase at https://shop.aap.org/textbook-of-neonatal-resuscitation-8th-edition-paperback/ (NOTE: This book features a full text reading experience. Establishing ventilation is the most important step to correct low heart rate. Flush the UVC with normal saline. Oximetry and electrocardiography are important adjuncts in babies requiring resuscitation. 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). During resuscitation, supplemental oxygen may be provided to prevent harm from inadequate oxygen supply to tissues (hypoxemia).4 However, overexposure to oxygen (hyperoxia) may be associated with harm.5, Term and late preterm newborns have lower shortterm mortality when respiratory support during resuscitation is started with 21% oxygen (air) versus 100% oxygen.1 No difference was found in neurodevelopmental outcome of survivors.1 During resuscitation, pulse oximetry may be used to monitor oxygen saturation levels found in healthy term infants after vaginal birth at sea level.3, In more preterm newborns, there were no differences in mortality or other important outcomes when respiratory support was started with low (50% or less) versus high (greater than 50%) oxygen concentrations.2 Given the potential for harm from hyperoxia, it may be reasonable to start with 21% to 30% oxygen. NRP courses are moving from the HealthStream platform to RQI. You're welcome to take the quiz as many times as you'd like. The studies were too heterogeneous to be amenable to meta-analysis. A 3:1 ratio of compressions to ventilation provided more ventilations than higher ratios in manikin studies. Contact Us, Hours Babies who have failed to respond to PPV and chest compressions require vascular access to infuse epinephrine and/or volume expanders. Together with other professional societies, the AHA has provided interim guidance for basic and advanced life support in adults, children, and neonates with suspected or confirmed coronavirus disease 2019 (COVID-19) infection. None of these studies evaluate outcomes of resuscitation that extends beyond 20 minutes of age, by which time the likelihood of intact survival was very low. Suctioning may be considered if PPV is required and the airway appears obstructed. Each of these resulted in a description of the literature that facilitated guideline development.1417, Each AHA writing group reviewed all relevant and current AHA guidelines for CPR and ECC1820 and all relevant 2020 ILCOR International Consensus on CPR and ECC Science With Treatment Recommendations evidence and recommendations21 to determine if current guidelines should be reaffirmed, revised, or retired, or if new recommendations were needed. This is partly due to the challenges of performing large randomized controlled trials (RCTs) in the delivery room. Supplemental oxygen: 100 vs. 21 percent (room air). A randomized study showed similar success in providing effective ventilation using either laryngeal mask airway or endotracheal tube. Coordinate chest compressions with ventilations at a ratio of 3:1 and a rate of 120 events per minute to achieve approximately 90 compressions and 30 breaths per minute. The dose of epinephrine can be re-peated after 3-5 minutes if the initial dose is ineffective or can be repeated immediately if initial dose is given by endo-tracheal tube in the absence of an intravenous access. For term infants who do not require resuscitation at birth, it may be reasonable to delay cord clamping for longer than 30 seconds. Chest compressions are a rare event in full-term newborns (approximately 0.1%) but are provided more frequently to preterm newborns.11When providing chest compressions to a newborn, it may be reasonable to deliver 3 compressions before or after each inflation: providing 30 inflations and 90 compressions per minute (3:1 ratio for 120 total events per minute). Researchers studying these gaps may need to consider innovations in clinical trial design; examples include pragmatic study designs and novel consent processes. One observational study compared neonatal outcomes before (historical cohort) and after implementation of ECG monitoring in the delivery room. 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. The potential benefit or harm of sustained inflations between 1 and 10 seconds is uncertain.2,29. When providing chest compressions with the 2 thumbencircling hands technique, the hands encircle the chest while the thumbs depress the sternum.1,2 The 2 thumbencircling hands technique can be performed from the side of the infant or from above the head of the newborn.1 Performing chest compressions with the 2 thumbencircling hands technique from above the head facilitates placement of an umbilical venous catheter. It may be reasonable to provide volume expansion with normal saline (0.9% sodium chloride) or blood at 10 to 20 mL/kg. During 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. Metrics. History and physical examination findings suggestive of blood loss include a pale appearance, weak pulses, and persistent bradycardia (heart rate less than 60/min). In newborns who do not require resuscitation, delaying cord clamping for more than 30 seconds reduces anemia, especially in preterm infants. This material may not otherwise be downloaded, copied, printed, stored, transmitted or reproduced in any medium, whether now known or later invented, except as authorized in writing by the AAFP. TALKAD S. RAGHUVEER, MD, AND AUSTIN J. COX, MD. If the heart rate remains less than 60/min despite 60 seconds of chest compressions and adequate PPV, epinephrine should be administered, ideally via the intravenous route. Newer methods of chest compression, using a sustained inflation that maintains lung inflation while providing chest compressions, are under investigation and cannot be recommended at this time outside research protocols.12,13. In babies who appear to have ineffective respiratory effort after birth, tactile stimulation is reasonable. Umbilical venous catheterization is the recommended vascular access, although it has not been studied. Admission temperature should be routinely recorded. Briefing has been defined as a discussion about an event that is yet to happen to prepare those who will be involved and thereby reduce the risk of failure or harm.4 Debriefing has been defined as a discussion of actions and thought processes after an event to promote reflective learning and improve clinical performance5 or a facilitated discussion of a clinical event focused on learning and performance improvement.6 Briefing and debriefing have been recommended for neonatal resuscitation training since 20107 and have been shown to improve a variety of educational and clinical outcomes in neonatal, pediatric, and adult simulation-based and clinical studies. Endotracheal intubation is indicated in very premature infants; for suctioning of nonvigorous infants born through meconium-stained amniotic fluid; and when bag and mask ventilation is necessary for more than two to three minutes, PPV via face mask does not increase heart rate, or chest compressions are needed. A systematic review (low to moderate certainty) of 6 RCTs showed that early skin-to-skin contact promotes normothermia in healthy neonates. Because evidence and guidance are evolving with the COVID-19 situation, this interim guidance is maintained separately from the ECC guidelines. Endotracheal suctioning may be useful in nonvigorous infants with respiratory depression born through meconium-stained amniotic fluid. NRP Advanced is suited for health care professionals who serve as members of the resuscitation team in the delivery room or in other settings where complex neonatal resuscitation is required. 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. Approximately 10% of newborns require assistance to breathe after birth.13,5,13 Newborn resuscitation requires training, preparation, and teamwork. See permissionsforcopyrightquestions and/or permission requests. Consequently, all newly born babies should be attended to by at least 1 person skilled and equipped to provide PPV. PEEP has been shown to maintain lung volume during PPV in animal studies, thus improving lung function and oxygenation.16 PEEP may be beneficial during neonatal resuscitation, but the evidence from human studies is limited. In newborns born before 35 weeks' gestation, oxygen concentrations above 50% are no more effective than lower concentrations. RQI for NRP. According to the Textbook of Neonatal Resuscitation, 8th edition algorithm, at what point during resuscitation is a cardiac monitor recommended to assess the baby's heart rate? 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. 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. Tell your doctor if you have ever had: heart disease or high blood pressure; asthma; Parkinson's disease; depression or mental illness; a thyroid disorder; or. Before using epinephrine, tell your doctor if any past use of epinephrine injection caused an allergic reaction to get worse. 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. After birth, the newborn's heart rate is used to assess the effectiveness of spontaneous respiratory effort, the need for interventions, and the response to interventions. Providing PPV at a rate of 40 to 60 inflations per minute is based on expert opinion. The heart rate should be verbalized for the team. 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. Copyright 2021 by the American Academy of Family Physicians. Infants 36 weeks or greater estimated gestational age who receive advanced resuscitation should be examined for evidence of HIE to determine if they meet criteria for therapeutic hypothermia. 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. Early skin-to-skin contact benefits healthy newborns who do not require resuscitation by promoting breastfeeding and temperature stability. Copyright 2023 American Academy of Family Physicians. In preterm newborns (less than 35 wk of gestation) receiving respiratory support at birth, it may be reasonable to begin with 21% to 30% oxygen with subsequent oxygen titration based on pulse oximetry. This material may not otherwise be downloaded, copied, printed, stored, transmitted or reproduced in any medium, whether now known or later invented, except as authorized in writing by the AAFP. Intrapartum suctioning is not recommended in infants born through meconium-stained amniotic fluid. How soon after administration of intravenous epinephrine should you pause compressions and assess the baby's heart rate?a. Intravenous epinephrine is preferred because. Heart rate is assessed initially by auscultation and/or palpation. 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. Similarly, meta-analysis of 2 quasi-randomized trials showed no difference in moderate-to-severe neurodevelopmental impairment at 1 to 3 years of age. 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). Optimal PEEP has not been determined, because all human studies used a PEEP level of 5 cm H2O.1822, It is reasonable to initiate PPV at a rate of 40 to 60/min to newly born infants who have ineffective breathing, are apneic, or are persistently bradycardic (heart rate less than 100/min) despite appropriate initial actions (including tactile stimulation).1, To match the natural breathing pattern of both term and preterm newborns, the inspiratory time while delivering PPV should be 1 second or less. 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. Epinephrine is indicated if the heart rate remains below 60 beats per minute despite 60 seconds of chest compressions and adequate ventilation. The 2015 Neonatal Resuscitation Algorithm and the major concepts based on sections of the algorithm continue to be relevant in 2020 (Figure(link opens in new window)(link opens in new window)). Check the heart rate by counting the beats in 6 seconds and multiply by 10. 7272 Greenville Ave. Exothermic mattresses have been reported to cause local heat injury and hyperthermia.15, When babies are born in out-of-hospital, resource-limited, or remote settings, it may be reasonable to prevent hypothermia by using a clean food-grade plastic bag13 as an alternative to skin-to-skin contact.8. Radiant warmers and other warming adjuncts are suggested for babies who require resuscitation at birth, especially very preterm and very low-birth-weight babies. When do chest compressions stop NRP? Epinephrine is indicated if the heart rate remains below 60 beats per minute despite 60 seconds of chest compressions and adequate ventilation. Effective and timely resuscitation at birth could therefore improve neonatal outcomes further. We thank Dr. Abhrajit Ganguly for assistance in manuscript preparation. 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. 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.
