Suction should also be considered if there is evidence of airway obstruction during PPV, Direct laryngoscopy and endotracheal suctioning are not routinely required for babies born through MSAF but can be beneficial in babies who have evidence of airway obstruction while receiving PPV.7. The writing groups then drafted, reviewed, and approved recommendations, assigning to each a Level of Evidence (LOE; ie, quality) and Class of Recommendation (COR; ie, strength) (Table(link opens in new window)).11. Premature animals exposed to brief high tidal volume ventilation (from high PIP) develop lung injury, impaired gas exchange, and decreased lung compliance. Ventilation of the lungs results in a rapid increase in heart rate. Hyperlinked references are provided to facilitate quick access and review. In term and preterm newly born infants, it is reasonable to initiate PPV with an inspiratory time of 1 second or less. 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. Routine oral, nasal, oropharyngeal, or endotracheal suctioning of newly born babies is not recommended. 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. A new Resuscitation Quality Improvement (RQI) program for NRP focused on PPV will be . 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. Intra-arterial epinephrine is not 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). In term and late preterm newborns (35 wk or more of gestation) receiving respiratory support at birth, the initial use of 21% oxygen is reasonable. Test your knowledge with our free Neonatal Resuscitation Practice Test provided below in order to prepare you for our official online exam. Epinephrine (adrenaline) is the only medication recommended by the International Liaison Committee On Resuscitation (ILCOR) during resuscitation in newborns with persistent bradycardia or .

CPAP, a form of respiratory support, helps newly born infants keep their lungs open. High-quality observational studies of large populations may also add to the evidence. Effective team behaviors, such as anticipation, communication, briefing, equipment checks, and assignment of roles, result in improved team performance and neonatal outcome. 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. Epinephrine is indicated if the heart rate remains below 60 beats per minute despite 60 seconds of chest compressions and adequate ventilation. The newly born period extends from birth to the end of resuscitation and stabilization in the delivery area. PPV may be initiated with air (21% oxygen) in term and late preterm babies, and up to 30% oxygen in preterm babies. For babies requiring vascular access at the time of delivery, the umbilical vein is the recommended route. 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. Oximetry and electrocardiography are important adjuncts in babies requiring resuscitation. ** 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: Reduce the inflation pressure if the chest is moving well. The dosage interval for epinephrine is every 3 to 5 minutes if the heart rate remains less than 60/min, although an intravenous dose may be given as soon as umbilical access is obtained if response to endotracheal epinephrine has been inadequate. If the neonate's heart rate is less than 60 bpm after optimal ventilation for 30 seconds, the oxygen concentration should be increased to 100% with commencement of chest compressions. NRP courses are moving from the HealthStream platform to RQI. Every birth should be attended by one person who is assigned, trained, and equipped to initiate resuscitation and deliver positive pressure ventilation. Pulse oximetry tended to underestimate the newborn's heart rate. In addition, specific recommendations about the training of resuscitation providers and systems of care are provided in their respective guideline Parts.9,10. Equipment checklists, role assignments, and team briefings improve resuscitation performance and outcomes. Both hands encircling chest Thumbs side by side or overlapping on lower half of . All guidelines were reviewed and approved for publication by the AHA Science Advisory and Coordinating Committee and AHA Executive Committee. For term and preterm infants who require resuscitation at birth, there is insufficient evidence to recommend early cord clamping versus delayed cord clamping. The heart rate should be re- checked after 1 minute of giving compressions and ventilations. Suctioning may be considered if PPV is required and the airway appears obstructed. When appropriate, flow diagrams or additional tables are included. In a retrospective study, volume infusion was given more often for slow response of bradycardia to resuscitation than for overt hypovolemia. 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. Please contact the American Heart Association at ECCEditorial@heart.org or 1-214-706-1886 to request a long description of . Therefore, identifying a rapid and reliable method to measure the newborn's heart rate is critically important during neonatal resuscitation. A single-center RCT found that role confusion during simulated neonatal resuscitation was avoided and teamwork skills improved by conducting a team briefing. Author disclosure: No relevant financial affiliations. 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. 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. Copyright 2021 by the American Academy of Family Physicians. It is important to continue PPV and chest compressions while preparing to deliver medications. 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. There was no difference in neonatal intubation performance after weekly booster practice for 4 weeks compared with daily booster practice for 4 consecutive days. Prevention of hyperthermia (temperature greater than 38C) is reasonable due to an increased risk of adverse outcomes. For preterm infants who do not require resuscitation at birth, it is reasonable to delay cord clamping for longer than 30 seconds. Newborn temperature should be maintained between 97.7F and 99.5F (36.5C and 37.5C), because mortality and morbidity increase with hypothermia, especially in preterm and low birth weight infants. During One observational study compared neonatal outcomes before (historical cohort) and after implementation of ECG monitoring in the delivery room. 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. HR below 60/min? One RCT (low certainty of evidence) suggests improved oxygenation after resuscitation in preterm babies who received repeated tactile stimulation. Depth is correct. 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. High oxygen concentrations are recommended during chest compressions based on expert opinion. However, the concepts in these guidelines may be applied to newborns during the neonatal period (birth to 28 days). The recommended route is intravenous, with the intraosseous route being an alternative. Initiate effective PPV for 30 seconds and reassess the heart rate. For neonatal resuscitation providers, it may be reasonable to brief before delivery and debrief after neonatal resuscitation. The temperature of newly born babies should be maintained between 36.5C and 37.5C after birth through admission and stabilization. What is true about a pneumothorax in the newborn? Exhaled carbon dioxide detectors can be used to confirm endotracheal tube placement in an infant. - 14446398 Volunteers with recognized expertise in resuscitation are nominated by the writing group chair and selected by the AHA ECC Committee. If a baby does not begin breathing . 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 . This is partly due to the challenges of performing large randomized controlled trials (RCTs) in the delivery room. 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. 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. 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]. There was no difference in Apgar scores or blood gas with naloxone compared with placebo. 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. A nonrandomized trial showed that endotracheal suctioning did not decrease the incidence of meconium aspiration syndrome or mortality. There should be ongoing evaluation of the baby for normal respiratory transition. Copyright 2023 American Academy of Family Physicians. 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. 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. 1. 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. 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. Rapid and effective response and performance are critical to good newborn outcomes. A systematic review (low to moderate certainty) of 6 RCTs showed that early skin-to-skin contact promotes normothermia in healthy neonates. 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. With secondary apnea, the heart rate continues to drop, and blood pressure decreases as well. If intravenous access is not feasible, it may be reasonable to use the intraosseous route. Higher doses (0.05 to 0.1 mg per kg) of endotracheal epinephrine are needed to achieve an increase in blood epinephrine concentration. 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. When the need for resuscitation is not anticipated, delays in assisting a newborn who is not breathing may increase the risk of death.1,5,13 Therefore, every birth should be attended by at least 1 person whose primary responsibility is the newborn and who is trained to begin PPV without delay.24, A risk assessment tool that evaluates risk factors present during pregnancy and labor can identify newborns likely to require advanced resuscitation; in these cases, a team with more advanced skills should be mobilized and present at delivery.5,7 In the absence of risk stratification, up to half of babies requiring PPV may not be identified before delivery.6,13, A standardized equipment checklist is a comprehensive list of critical supplies and equipment needed in a given clinical setting. 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. Post-resuscitation care. In the delivery room setting, the primary method of vascular access is umbilical venous catheterization. Supplemental oxygen should be used judiciously, guided by pulse oximetry. A multicenter randomized trial showed that intrapartum suctioning of meconium does not reduce the risk of meconium aspiration syndrome. No type of routine suctioning is helpful, even for nonvigorous newborns delivered through meconium-stained amniotic fluid. Oximetry is used to target the natural range of oxygen saturation levels that occur in term babies. For infants with a heart rate of 60 to < 100 beats/minute who have apnea, gasping, or ineffective respirations, positive pressure ventilation (PPV) using a mask is indicated.
