Animal studies in newborn mammals show that heart rate decreases during asphyxia. 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. Even healthy babies who breathe well after birth benefit from facilitation of normal transition, including appropriate cord management and thermal protection with skin-to-skin care. Before giving PPV, the airway should be cleared by gently suctioning the mouth first and then the nose with a bulb syringe. Copyright 2011 by the American Academy of Family Physicians. 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). 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. NRP 8th Edition Test Flashcards | Quizlet 2023 American Heart Association, Inc. All rights reserved. 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. 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. IV epinephrine every 3-5 minutes. If it is possible to identify such conditions at or before birth, it is reasonable not to initiate resuscitative efforts. Intravenous epinephrine is preferred because. Rescuer 2 verbalizes the need for chest compressions. Many current recommendations are based on weak evidence with a lack of well-designed human studies. PDF NEONATAL RESUSCITATION - Oregon Two observational studies found an association between hyperthermia and increased morbidity and mortality in very preterm (moderate quality) and very low-birth-weight neonates (very low quality). Wrapping, in addition to radiant heat, improves admission temperature of preterm infants. Cord milking in preterm infants should be avoided because of increased risk of intraventricular hemorrhage. 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 primary goal of neonatal care at birth is to facilitate transition. 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). A team or persons trained in neonatal resuscitation should be promptly available to provide resuscitation. It is important to recognize that there are several significant gaps in knowledge relating to neonatal resuscitation. A randomized study showed similar success in providing effective ventilation using either laryngeal mask airway or endotracheal tube. Although this flush volume may . Ventilation of the lungs results in a rapid increase in heart rate. No studies have examined PEEP vs. no PEEP when positive pressure ventilation is used after birth. 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]. The American Heart Association released minor updates to neonatal resuscitation recommendations with only minor changes to the previous algorithm (Figure 1). Every birth should be attended by one person who is assigned, trained, and equipped to initiate resuscitation and deliver positive pressure ventilation. When should I check heart rate after epinephrine? 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. 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. The intravenous dose of epinephrine is 0.01 to 0.03 mg/kg, followed by a normal saline flush.4 If umbilical venous access has not yet been obtained, epinephrine may be given by the endotracheal route in a dose of 0.05 to 0.1 mg/kg. However, it may be reasonable to increase inspired oxygen to 100% if there was no response to PPV with lower concentrations. Test your knowledge with our free Neonatal Resuscitation Practice Test provided below in order to prepare you for our official online exam. 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. Part 5: neonatal resuscitation: 2020 American Heart Association Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care. 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. 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. When Should I Check Heart Rate After Epinephrine Supplemental oxygen: 100 vs. 21 percent (room air). All guidelines were reviewed and approved for publication by the AHA Science Advisory and Coordinating Committee and AHA Executive Committee. Readers are directed to the AHA website for the most recent guidance.12, The following sections briefly describe the process of evidence review and guideline development. Birth 1 minute If HR remains <60 bpm, Consider hypovolemia. 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. A reasonable time frame for this change in goals of care is around 20 min after birth. 1 minuteb. If intravenous access is not feasible, it may be reasonable to use the intraosseous route. Two randomized trials and 1 quasi-randomized trial (very low quality) including 312 infants compared PPV with a T-piece (with PEEP) versus a self-inflating bag (no PEEP) and reported similar rates of death and chronic lung disease. Three different types of evidence reviews (systematic reviews, scoping reviews, and evidence updates) were used in the 2020 process. Auscultation of the precordium remains the preferred physical examination method for the initial assessment of the heart rate.9 Pulse oximetry and ECG remain important adjuncts to provide continuous heart rate assessment in babies needing resuscitation. Newly born infants who required advanced resuscitation are at significant risk of developing moderate-to-severe HIE. Reassess heart rate and breathing at least every 30 seconds. In newborns born before 35 weeks' gestation, oxygen concentrations above 50% are no more effective than lower concentrations. There was no difference in neonatal intubation performance after weekly booster practice for 4 weeks compared with daily booster practice for 4 consecutive days. The newly born period extends from birth to the end of resuscitation and stabilization in the delivery area. Very low-quality evidence from 8 nonrandomized studies. When appropriate, flow diagrams or additional tables are included. There is a reduction of mortality and no evidence of harm in term infants resuscitated with 21 percent compared with 100 percent oxygen. Table 1. 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. 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. Certificate Site - NRP Learning Platform 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 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. 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. PPV remains the primary method for providing support for newborns who are apneic, bradycardic, or demonstrate inadequate respiratory effort. Applying Class of Recommendation and Level of Evidence to Clinical Strategies, Interventions, Treatments, or Diagnostic Testing in Patient 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. 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. Neonatal Resuscitation Pre Test Example Quiz & Answers - HCP Certifications If the response to chest compressions is poor, it may be reasonable to provide epinephrine, preferably via the intravenous route. There is a history of acute blood loss around the time of delivery. It is important to. HR below 60/min? When providing chest compressions to a newborn, the 2 thumbencircling hands technique may have benefit over the 2-finger technique with respect to blood pressure generation and provider fatigue. Evidence suggests that warming can be done rapidly (0.5C/h) or slowly (less than 0.5C/h) with no significant difference in outcomes.1519 Caution should be taken to avoid overheating. Plasma epinephrine concentrations at 1 min after epinephrine administration were not different. 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. See Part 2: Evidence Evaluation and Guidelines Development for more details on this process.11. Neonatal Resuscitation: Updated Guidelines from the American Heart According to the Textbook of Neonatal Resuscitation, 8th edition, what volume of normal saline flush should you administer? 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. 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 other situations, clamping and cutting of the cord may also be deferred while respiratory, cardiovascular, and thermal transition is evaluated and initial steps are undertaken. There are limited data comparing the different approaches to heart rate assessment during neonatal resuscitation on other neonatal outcomes. Copyright 2023 American Academy of Family Physicians. Identification of risk factors for resuscitation may indicate the need for additional personnel and equipment. Wait 60 seconds and check the heart rate. If the infant's heart rate is less than 100 bpm, PPV via face mask (not mask continuous positive airway pressure) is initiated at a rate of 40 to 60 breaths per minute to achieve and maintain a heart rate of more than 100 bpm.1,2,57 PPV can be administered via flow-inflating bag, self-inflating bag, or T-piece device.1,6 There is no major advantage of using one ventilatory device over another.23 Thus, each institution should standardize its equipment and train the neonatal resuscitation team appropriately. Most changes are related to program administration and course facilitation. An important point is that ventilation has been shown to be the most effective measure in neonatal resuscitation The reduced heart rate that occurs in this situation can be reversed with tactile stimulation. 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. Supplemental oxygen should be used judiciously, guided by pulse oximetry. Delayed umbilical cord clamping was recommended for both term and preterm neonates in 2015. What is true about a pneumothorax in the newborn? During chest compressions, an ECG should be used for the rapid and accurate assessment of heart rate. It is reasonable to perform all resuscitation procedures, including endotracheal intubation, chest compressions, and insertion of intravenous lines with temperature-controlling interventions in place. Positive-pressure ventilation (PPV) remains the main intervention in neonatal resuscitation. Positive pressure ventilation should be delivered without delay to infants who are apneic, gasping, or have a heart rate below 100 beats per minute within the first 60 seconds of life despite initial resuscitation.
