Consider pneumothorax. A nonrandomized trial showed that endotracheal suctioning did not decrease the incidence of meconium aspiration syndrome or mortality. 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. A meta-analysis (very low quality) of 8 animal studies (n=323 animals) that compared air with 100% oxygen during chest compressions showed equivocal results. 2020;142(suppl 2):S524S550. With the symptoms of The dose of epinephrine is .5-1ml/kg by ETT or .1-.3ml/kg in the concentration of 1:10,000 (0.1mg/ml), which is to be followed by 0.5-1ml flush of normal saline. The impact of therapeutic hypothermia on infants less than 36 weeks gestational age with HIE is unclear and is a subject of ongoing research trials. Comprehensive disclosure information for peer reviewers is listed in Appendix 2(link opens in new window). 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. Every birth should be attended by one person who is assigned, trained, and equipped to initiate resuscitation and deliver positive pressure ventilation. This guideline affirms the previous recommendations. In a randomized controlled simulation study, medical students who underwent booster training retained improved neonatal intubation skills over a 6-week period compared with medical students who did not receive booster training. For neonatal resuscitation providers, it may be reasonable to brief before delivery and debrief after neonatal resuscitation. Very low-quality evidence from 2 nonrandomized studies and 1 randomized trial show that auscultation is not as accurate as ECG for heart rate assessment during newborn stabilization immediately after birth. A randomized study showed similar success in providing effective ventilation using either laryngeal mask airway or endotracheal tube. 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. 2023 American Heart Association, Inc. All rights reserved. Physicians who provide obstetric care should be aware of maternal-fetal risk factors1 and should assess the risk of respiratory depression with each delivery.19 The obstetric team should inform the neonatal resuscitation team of the risk status for each delivery and continue to focus on obstetric care. When epinephrine is required, multiple doses are commonly needed. Comprehensive disclosure information for writing group members is listed in Appendix 1(link opens in new window). Hypothermia (temperature less than 36C) should be prevented due to an increased risk of adverse outcomes. The heart rate should be re- checked after 1 minute of giving compressions and ventilations. Intrapartum suctioning is not recommended in infants born through meconium-stained amniotic fluid. Both hands encircling chest Thumbs side by side or overlapping on lower half of . 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. Teams and individuals who provide neonatal resuscitation are faced with many challenges with respect to the knowledge, skills, and behaviors needed to perform effectively. 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. These guidelines apply primarily to the newly born baby who is transitioning from the fluid-filled womb to the air-filled room. If all these steps of resuscitation are effectively completed and there is no heart rate response by 20 minutes, redirection of care should be discussed with the team and family. Supplemental oxygen should be used judiciously, guided by pulse oximetry. There are limited data comparing the different approaches to heart rate assessment during neonatal resuscitation on other neonatal outcomes. 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. In addition, specific recommendations about the training of resuscitation providers and systems of care are provided in their respective guideline Parts.9,10. 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. When the heart rate increases to more than 100 bpm, PPV may be discontinued if there is effective respiratory effort.5 Oxygen is decreased and discontinued once the infant's oxygen saturation meets the targeted levels (Figure 1).5, If there is no heartbeat after 10 minutes of adequate resuscitative efforts, the team can cease further resuscitation.1,5,6 A member of the team should keep the family informed during the resuscitation process. Successful neonatal resuscitation efforts depend on critical actions that must occur in rapid succession to maximize the chances of survival. How deep should the catheter be inserted? 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. When ECG heart rate is greater than 60/min, a palpable pulse and/or audible heart rate rules out pulseless electric activity.1721, The vast majority of newborns breathe spontaneously within 30 to 60 seconds after birth, sometimes after drying and tactile stimulation.1 Newborns who do not breathe within the first 60 seconds after birth or are persistently bradycardic (heart rate less than 100/min) despite appropriate initial actions (including tactile stimulation) may receive PPV at a rate of 40 to 60/min.2,3 The order of resuscitative procedures in newborns differs from pediatric and adult resuscitation algorithms. For nonvigorous newborns with meconium-stained fluid, endotracheal suctioning is indicated only if obstruction limits positive pressure ventilation, because suctioning does not improve outcomes. Wait 60 seconds and check the heart rate. 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. With growing enthusiasm for clinical studies in neonatology, elements of the Neonatal Resuscitation Algorithm continue to evolve as new evidence emerges. Pulse oximetry is used to guide oxygen therapy and meet oxygen saturation goals. There is no evidence from randomized trials to support the use of volume resuscitation at delivery. It is important to recognize that there are several significant gaps in knowledge relating to neonatal resuscitation. Flush the UVC with normal saline. A team or persons trained in neonatal resuscitation should be promptly available to provide resuscitation. Before every birth, a standardized equipment checklist should be used to ensure the presence and function of supplies and equipment necessary for a complete resuscitation. No studies have examined PEEP vs. no PEEP when positive pressure ventilation is used after birth. To perform neonatal resuscitation effectively, individual providers and teams need training in the required knowledge, skills, and behaviors. A large observational study found that delaying PPV increases risk of death and prolonged hospitalization. Given the evidence for ECG during initial steps of PPV, expert opinion is that ECG should be used when providing chest compressions. During resuscitation of term and preterm newborns, the use of electrocardiography (ECG) for the rapid and accurate measurement of the newborns heart rate may be reasonable. 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. Effective team behaviors, such as anticipation, communication, briefing, equipment checks, and assignment of roles, result in improved team performance and neonatal outcome. There is a reduction of mortality and no evidence of harm in term infants resuscitated with 21 percent compared with 100 percent oxygen. See permissionsforcopyrightquestions and/or permission requests. 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. Team debrieng. The heart rate response to chest compressions and medications should be monitored electrocardiographically. 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. Although this flush volume may . 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. During What is true about a pneumothorax in the newborn? 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. 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. If intravenous access is not feasible, it may be reasonable to use the intraosseous route. Positive-Pressure Ventilation (PPV) 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. Median time to ROSC and cumulative epinephrine dose required were not different. High-quality observational studies of large populations may also add to the evidence. In the resuscitation of an infant, initial oxygen concentration of 21 percent is recommended. Hypothermia after birth is common worldwide, with a higher incidence in babies of lower gestational age and birth weight. While this research has led to substantial improvements in the Neonatal Resuscitation Algorithm, it has also highlighted that we still have more to learn to optimize resuscitation for both preterm and term infants. Table 1 lists evidence and recommendations for interventions during neonatal resuscitation.1,2,57,2043, Intrapartum suctioning is not recommended with clear or meconium-stained amniotic fluid.1,2,5,6, Endotracheal suctioning of vigorous* infants is not recommended.1,2,5,6, Endotracheal suctioning of nonvigorous infants born through meconium-stained amniotic fluid may be useful.1,2,5, A self-inflating bag, flow-inflating bag, or T-piece device can be used to deliver positive pressure ventilation.1,6, Auscultation should be the primary means of assessing heart rate, and in infants needing respiratory support, the goal should be to check the heart rate by auscultation and by pulse oximetry.6, Initial PIP of 20 cm H2O may be effective, but a PIP of 30 to 40 cm H2O may be necessary in some infants to achieve or maintain a heart rate of more than 100 bpm.5, Ventilation rates of 40 to 60 breaths per minute are recommended.5,6, Use of an exhaled carbon dioxide detector in term and preterm infants is recommended to confirm endotracheal tube placement.5,6, Laryngeal mask airway should be considered if bag and mask ventilation is unsuccessful, and if endotracheal intubation is unsuccessful or not feasible.5,6, No evidence exists to support or refute the use of mask CPAP in term infants.2,5, PEEP should be used if suitable equipment is available, such as a flow-inflating bag or T-piece device.5, Delivery rooms should have a pulse oximeter readily available.57, A pulse oximeter is recommended when supplemental oxygen, positive pressure ventilation, or CPAP is used.57, Supplemental oxygen should be administered using an air/oxygen blender.57. 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)). 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. Tactile stimulation should be limited to drying an infant and rubbing the back and soles of the feet.21,22 There may be some benefit from repeated tactile stimulation in preterm babies during or after providing PPV, but this requires further study.23 If, at initial assessment, there is visible fluid obstructing the airway or a concern about obstructed breathing, the mouth and nose may be suctioned. Clinical assessment of heart rate has been found to be both unreliable and inaccurate. The dose of Epinephrine via the UVC is 0.1 mg/kg - 0.5 mg/kg It may be easier for you to use 0.1 mg/kg for the UVC access.. For an infant weighing 1 kg the dose becomes 0.1 ml. Copyright 2023 American Academy of Family Physicians. If heart rate after birth remains at less than 60/min despite adequate ventilation for at least 30 s, initiating chest compressions is reasonable. In a randomized trial, the use of mask CPAP compared with endotracheal intubation and mechanical ventilation in spontaneously breathing preterm infants decreased the risk of bronchopulmonary dysplasia or death, and decreased the use of surfactant, but increased the rate of pneumothorax. If the heart rate is less than 60 bpm, begin chest compressions. For participants who have been trained in neonatal resuscitation, individual or team booster training should occur more frequently than every 2 yr at a frequency that supports retention of knowledge, skills, and behaviors. This series is coordinated by Michael J. Arnold, MD, contributing editor. Please contact the American Heart Association at ECCEditorial@heart.org or 1-214-706-1886 to request a long description of . Routine oral, nasal, oropharyngeal, or endotracheal suctioning of newly born babies is not recommended. 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? 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. Therapeutic hypothermia is provided under defined protocols similar to those used in published clinical trials and in facilities capable of multidisciplinary care and longitudinal follow-up. The temperature of newly born babies should be maintained between 36.5C and 37.5C after birth through admission and stabilization. If there is ineffective breathing effort or apnea after birth, tactile stimulation may stimulate breathing. In newborns born before 35 weeks' gestation, oxygen concentrations above 50% are no more effective than lower concentrations. 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]. Currently, epinephrine is the only vasoactive drug recommended by the International Liaison Committee on Resuscitation (ILCOR) for neonates who remain severely bradycardic (heart rate <. These situations benefit from expert consultation, parental involvement in decision-making, and, if indicated, a palliative care plan.1,2,46. The AHA has rigorous conflict of interest policies and procedures to minimize the risk of bias or improper influence during development of the guidelines.13 Before appointment, writing group members and peer reviewers disclosed all commercial relationships and other potential (including intellectual) conflicts. Aim for about 30 breaths min-1 with an inflation time of ~one second. We thank Dr. Abhrajit Ganguly for assistance in manuscript preparation. Delayed cord clamping is associated with higher hematocrit after birth and better iron levels in infancy.921 While developmental outcomes have not been adequately assessed, iron deficiency is associated with impaired motor and cognitive development.2426 It is reasonable to delay cord clamping (longer than 30 seconds) in preterm babies because it reduces need for blood pressure support and transfusion and may improve survival.18, There are insufficient studies in babies requiring PPV before cord clamping to make a recommendation.22 Early cord clamping should be considered for cases when placental transfusion is unlikely to occur, such as maternal hemorrhage or hemodynamic instability, placental abruption, or placenta previa.27 There is no evidence of maternal harm from delayed cord clamping compared with early cord clamping.1012,2834 Cord milking is being studied as an alternative to delayed cord clamping but should be avoided in babies less than 28 weeks gestational age, because it is associated with brain injury.23, Temperature should be measured and recorded after birth and monitored as a measure of quality.1 The temperature of newly born babies should be maintained between 36.5C and 37.5C.2 Hypothermia (less than 36C) should be prevented as it is associated with increased neonatal mortality and morbidity, especially in very preterm (less than 33 weeks) and very low-birthweight babies (less than 1500 g), who are at increased risk for hypothermia.35,7 It is also reasonable to prevent hyperthermia as it may be associated with harm.4,6, Healthy babies should be skin-to-skin after birth.8 For preterm and low-birth-weight babies or babies requiring resuscitation, warming adjuncts (increased ambient temperature [greater than 23C], skin-to-skin care, radiant warmers, plastic wraps or bags, hats, blankets, exothermic mattresses, and warmed humidified inspired gases)10,11,14 individually or in combination may reduce the risk of hypothermia. Once the heart rate increases to more than 60 bpm, chest compressions are stopped. In a prospective interventional clinical study, video-based debriefing of neonatal resuscitations was associated with improved preparation and adherence to the initial steps of the Neonatal Resuscitation Algorithm, improved quality of PPV, and improved team function and communication. Epinephrine (adrenaline) is the only medication recommended by the International Liaison Committee On Resuscitation (ILCOR) during resuscitation in newborns with persistent bradycardia or . For spontaneously breathing preterm infants who require respiratory support immediately after delivery, it is reasonable to use CPAP rather than intubation. An important point is that ventilation has been shown to be the most effective measure in neonatal resuscitation The studies were too heterogeneous to be amenable to meta-analysis. One moderate quality RCT found higher rates of hyperthermia with exothermic mattresses. 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. 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%). The Neonatal Resuscitation Program, which was initiated in 1987 to identify infants at risk of needing resuscitation and provide high-quality resuscitation, underwent major updates in 2006 and 2010. Premature animals exposed to brief high tidal volume ventilation (from high PIP) develop lung injury, impaired gas exchange, and decreased lung compliance.
