Once the neonatal resuscitation team is summoned to the delivery room, it is important to obtain a pertinent history; assign roles to each team member; check that all equipment is available and functional,1 including a pulse oximeter and an air/oxygen blender6; optimize room temperature for the infant; and turn on the warmer, light, oxygen, and suction. No type of routine suctioning is helpful, even for nonvigorous newborns delivered through meconium-stained amniotic fluid. Noninitiation of resuscitation and discontinuation of life-sustaining treatment during or after resuscitation should be considered ethically equivalent. Birth Antenatal counseling Team briefing and equipment check Neonatal Resuscitation Algorithm. 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%). 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. This content is owned by the AAFP. Rapid evaluation: this evaluation determines if the baby can stay wit the mother for routine care or should be moved to the radiant warmer Airway: The initial steps open the airway and support spontaneous respirations. 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. The same study demonstrated that the risk of death or prolonged admission increases 16% for every 30-second delay in initiating PPV. 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. Intrapartum suctioning is not recommended in infants born through meconium-stained amniotic fluid. When do chest compressions stop NRP? Ventilation should be optimized before starting chest compressions, possibly including endotracheal intubation. A multicenter, case-control study identified 10 perinatal risk factors that predict the need for advanced neonatal resuscitation. Exhaled carbon dioxide detectors to confirm endotracheal tube placement. Endotracheal suctioning for apparent airway obstruction with MSAF is based on expert opinion. 5 minutec. 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. 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. 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. Numerous nonrandomized quality improvement (very low to low certainty) studies support the use of warming adjunct bundles.. The primary objective of neonatal resuscitation is effective ventilation; an increase in heart rate indicates effective ventilation. In a case series, endotracheal epinephrine (0.01 mg per kg) was less effective than intravenous epinephrine. 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. For every 30 seconds that ventilation is delayed, the risk of prolonged admission or death increases by 16%. 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. Tactile stimulation is reasonable in newborns with ineffective respiratory effort, but should be limited to drying the infant and rubbing the back and the soles of the feet. "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) If the response to chest compressions is poor, it may be reasonable to provide epinephrine, preferably via the intravenous route. In resource-limited settings, it may be reasonable to place newly born babies in a clean food-grade plastic bag up to the level of the neck and swaddle them in order to prevent hypothermia. 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. Suctioning may be considered for suspected airway obstruction. Intraosseous needles are reasonable, but local complications have been reported. If epinephrine is administered via endotracheal tube, a dose of 0.05 to 0.1 mg per kg (1:10,000 solution) is needed.1,2,57, Early volume expansion with crystalloid (10 mL per kg) or red blood cells is indicated for blood loss when the heart rate does not increase with resuscitation.5,6, Use of naloxone is not recommended as part of initial resuscitation of infants with respiratory depression in the delivery room.1,2,5,6, Very rarely, sodium bicarbonate may be useful after resuscitation.6, Term or near term infants with evolving moderate to severe hypoxic-ischemic encephalopathy should be offered therapeutic hypothermia.57, Intravenous glucose infusion should be started soon after resuscitation to avoid hypoglycemia.5,6, It is recommended to cover preterm infants less than 28 weeks' gestation in polyethylene wrap after birth and place them under a radiant warmer. CPAP indicates continuous positive airway pressure; ECG, electrocardiographic; ETT, endotracheal tube; HR, heart rate; IV, intravenous; O2, oxygen; Spo2, oxygen saturation; and UVC, umbilical venous catheter. 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. Please contact the American Heart Association at ECCEditorial@heart.org or 1-214-706-1886 to request a long description of . Normal saline (0.9% sodium chloride) is the crystalloid fluid of choice. Oximetry and electrocardiography are important adjuncts in babies requiring resuscitation. 8 Assessment of Heart Rate During Neonatal Resuscitation 9 Ventilatory Support After Birth: PPV And Continuous Positive Airway Pressure 10 Oxygen Administration 11 Chest Compressions 12 Intravascular Access 13 Medications Epinephrine in Neonatal Resuscitation 14 Volume Replacement 15 Postresuscitation Care Prevention of hypothermia continues to be an important focus for neonatal resuscitation. In observational studies in both preterm (less than 37 weeks) and low-birth-weight babies (less than 2500 g), the presence and degree of hypothermia after birth is strongly associated with increased neonatal mortality and morbidity. Newly born infants born at 36 wk or more estimated gestational age with evolving moderate-to-severe HIE should be offered therapeutic hypothermia under clearly defined protocols. 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. 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. 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. After 30 seconds, Rescuer 2 evaluates heart rate. Naloxone and sodium bicarbonate are rarely needed and are not recommended during neonatal resuscitation. If you have a certificate code, then you can manually verify a certificate by entering the code here. The reduced heart rate that occurs in this situation can be reversed with tactile stimulation. 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. There is a history of acute blood loss around the time of delivery. 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. It is important to continue PPV and chest compressions while preparing to deliver medications. Supplemental oxygen: 100 vs. 21 percent (room air). 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). 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. 3 minuted. The most important priority for newborn survival is the establishment of adequate lung inflation and ventilation after birth. If the heart rate is less than 100 bpm and/or the infant has apnea or gasping respiration, positive pressure ventilation (PPV) via face mask is initiated with 21 percent oxygen (room air) or blended oxygen, and the pulse oximeter probe is applied to the right hand/wrist to monitor heart rate and oxygen saturation.5,6 The heart rate is reassessed after 30 seconds, and if it is less than 100 bpm, PPV is optimized to ensure adequate ventilation, and heart rate is checked again in 30 seconds.57 If the heart rate is less than 60 bpm after 30 seconds of effective PPV, chest compressions are started with continued PPV with 100 percent oxygen (3:1 ratio of compressions to ventilation; 90 compressions and 30 breaths per minute) for 45 to 60 seconds.57 If the heart rate continues to be less than 60 bpm despite adequate ventilation and chest compressions, epinephrine is administered via umbilical venous catheter (or less optimally via endotracheal tube).57, Depending on the skill of the resuscitator, the infant can be intubated and PPV delivered via endotracheal tube if chest compressions are needed or if bag and mask ventilation is prolonged or ineffective (with no chest rise).5 Heart rate, respiratory effort, and color are reassessed and verbalized every 30 seconds as PPV and chest compressions are performed. During an uncomplicated delivery, the newborn transitions from the low oxygen environment of the womb to room air (21% oxygen) and blood oxygen levels rise over several minutes. Aim for about 30 breaths min-1 with an inflation time of ~one second. In addition, accurate, fast, and continuous heart rate assessment is necessary for newborns in whom chest compressions are initiated. Glucose levels should be monitored as soon as practical after advanced resuscitation, with treatment as indicated. 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. Heart rate is assessed initially by auscultation and/or palpation. 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. Breakdowns in teamwork and communication can lead to perinatal death and injury.15 Team training in simulated resuscitations improves performance and has the potential to improve outcomes.16,17 Ultimately, being able to perform bag and mask ventilation and work in coordination with a team are important for effective neonatal resuscitation. 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.
