Use and efficacy of endotracheal versus intravenous epinephrine during neonatal cardiopulmonary resuscitation in the delivery room

Evaluating the efficacy of endotracheal and intranasal epinephrine administration in severely asphyxic bradycardic newborn lambs: a randomised preclinical study

OBJECTIVE

Intravenous epinephrine administration is preferred during neonatal resuscitation, but may not always be rapidly administered due to lack of equipment or trained staff. We aimed to compare the time to return of spontaneous circulation (ROSC) and post-ROSC haemodynamics between intravenous, endotracheal (ET) and intranasal (IN) epinephrine in severely asphyxic, bradycardic newborn lambs.

METHODS

After instrumentation, severe asphyxia (heart rate <60 bpm, blood pressure ~10 mm Hg) was induced by clamping the cord in near-term lambs. Resuscitation was initiated with ventilation followed by chest compressions. Lambs were randomly assigned to receive intravenous (0.02 mg/kg), ET (0.1 mg/kg) or IN (0.1 mg/kg) epinephrine. If ROSC was not achieved after three allocated treatment doses, rescue intravenous epinephrine was administered. After ROSC, lambs were ventilated for 60 min.

RESULTS

ROSC in response to allocated treatment occurred in 8/8 (100%) intravenous lambs, 4/7 (57%) ET lambs and 5/7 (71%) IN lambs. Mean (SD) time to ROSC was 173 (32) seconds in the intravenous group, 360 (211) seconds in the ET group and 401 (175) seconds in the IN group (p<0.05 intravenous vs IN). Blood pressure and cerebral oxygen delivery were highest in the intravenous group immediately post-ROSC (p<0.05), whereas the ET group sustained the highest blood pressure over the 60-min observation (p<0.05).

CONCLUSION

Our study supports neonatal resuscitation guidelines, highlighting intravenous administration as the most effective route for epinephrine. ET and IN epinephrine should only be considered when intravenous access is delayed or not feasible.

Newborn heart rate monitoring methods at birth and clinical outcomes: A systematic review

Aim

Compare heart rate assessment methods in the delivery room on newborn clinical outcomes.

Methods

A search of Medline, SCOPUS, CINAHL and Cochrane was conducted between January 1, 1946, to until August 16, 2023. (CRD 42021283438) Study Selection was based on predetermined criteria. Reviewers independently extracted data, appraised risk of bias and assessed certainty of evidence.

Results

Two randomized controlled trials involving 91 newborns and 1 nonrandomized study involving 632 newborns comparing electrocardiogram (ECG) to auscultation plus pulse oximetry were included. No studies were found that compared any other heart rate measurement methods and reported clinical outcomes. There was no difference between the ECG and control group for duration of positive pressure ventilation, time to heart rate ≥ 100 beats per minute, epinephrine use or death before discharge. In the randomized studies, there was no difference in rate of tracheal intubation [RR 1.34, 95% CI (0.69-2.59)]. No participants received chest compressions. In the nonrandomized study, fewer infants were intubated in the ECG group [RR 0.75, 95% CI (0.62-0.90)]; however, for chest compressions, benefit or harm could not be excluded. [RR 2.14, 95% (CI 0.98-4.70)].

Conclusion

There is insufficient evidence to ascertain clinical benefits or harms associated with the use of ECG versus pulse oximetry plus auscultation for heart rate assessment in newborns in the delivery room.

Outcomes after delivery room positive pressure ventilation in late preterm and term infants

Objectives

Characterize short-term outcomes of late preterm and term infants who received positive pressure ventilation in the delivery room and compare these with infants who did not receive resuscitation at birth.

Study Design

Single center retrospective cohort study of infants born between 35 0/7 and 41 6/7 weeks' gestation in 2019. Baseline characteristics and outcomes of infants who received positive pressure ventilation were compared with controls who did not receive delivery room ventilation. The primary outcome was neonatal intensive care unit admission; secondary outcomes included multiple hospital morbidities and interventions.

Results

Among 202 infants who received delivery room positive pressure ventilation, 77 (38.1%) received ≤1 min, and 125 (61.9%) received >1 min of positive pressure ventilation. Neonatal intensive care unit admission directly following resuscitation was more common in the ventilation cohort (33%) compared with controls (1.5%), p ≤ 0.0001. After initial admission to the newborn nursery, intensive care unit transfer rates were similar in the positive pressure ventilation cohort (4%) and controls (5%). Antibiotic exposure, hypoxic ischemic encephalopathy, respiratory support in the neonatal intensive care unit, and pneumothorax were more common in the ventilation cohort. The composite outcome of any post-delivery complication occurred in 45% of positive pressure ventilation-exposed infants, compared to 15.8% of control infants (<0.0001); this was more common following >1 min (52.8%) than ≤1 min positive pressure ventilation (32.5%), p = 0.002.

Conclusion

Post-delivery complications are common following delivery room positive pressure ventilation, emphasizing the need for post-resuscitation monitoring in either the neonatal intensive care unitor newborn nursery setting.

Improving pediatric procedural skills and EPA assessments through an acute care procedural skills curriculum

INTRODUCTION

Acute procedural skill competence is expected by the end of pediatric residency training; however, the extent to which residents are actually competent is not clear. Therefore, a cross-sectional observational study was performed to examine the competency of pediatric residents in acute care procedures in emergency medicine.

MATERIALS AND METHODS

Pediatric residents underwent didactic/hands-on "Acute Procedure Day" where they performed procedures with direct supervision and received entrustable professional activity (EPA) assessments (scores from 1-5) for each attempt. Procedures included: bag-valve mask (BVM) ventilation, intubation, intraosseous (IO) line insertion, chest tube insertion, and cardiopulmonary resuscitation (CPR) with defibrillation. Demographic information, perceived comfort level, and EPA data were collected. Descriptive statistics and Pearson correlation for postgraduate year (PGY) versus EPA scores were performed.

RESULTS

Thirty-six residents participated (24 PGY 1-2, and 12 PGY 3-4). Self-reported prior clinical exposure was lowest for chest tube placement (n = 3, 8.3%), followed by IOs (n = 19, 52.8%). During the sessions, residents showed the highest levels of first attempt proficiency with IO placement (EPA 4-5 in 28 residents/33 who participated) and BVM (EPA 4-5 in 27/33), and the lowest for chest tube placement (EPA 4-5 in 0/35), defibrillation (EPA 4-5 in 5/31 residents) and intubation (EPA 4-5 in 17/31). There was a strong correlation between PGY level and EPA score for intubation, but not for other skills.

DISCUSSION

Entrustability in acute care skills is not achieved with current pediatrics training. Research is needed to explore learning curves for skill acquisition and their relative importance.

Use of Initial Endotracheal Versus Intravenous Epinephrine During Neonatal Cardiopulmonary Resuscitation in the Delivery Room: Review of a National Database

OBJECTIVE

To assess whether initial epinephrine administration by endotracheal tube (ET) in newly born infants receiving chest compressions and epinephrine in the delivery room (DR) is associated with lower rates of return of spontaneous circulation (ROSC) than newborns receiving initial intravenous (IV) epinephrine.

STUDY DESIGN

We conducted a retrospective review of neonates receiving chest compressions and epinephrine in the DR from the AHA Get With The Guidelines-Resuscitation registry from October 2013 through July 2020. Neonates were classified according to initial route of epinephrine (ET vs IV). The primary outcome of interest was ROSC in the DR.

RESULTS

In total, 408 infants met inclusion criteria; of these, 281 (68.9%) received initial ET epinephrine and 127 (31.1%) received initial IV epinephrine. The initial ET epinephrine group included those infants who also received subsequent IV epinephrine when ET epinephrine failed to achieve ROSC. Comparing initial ET with initial IV epinephrine, ROSC was achieved in 70.1% vs 58.3% (adjusted risk difference 10.02; 95% CI 0.05-19.99). ROSC was achieved in 58.3% with IV epinephrine alone, and 47.0% with ET epinephrine alone, with 40.0% receiving subsequent IV epinephrine.

CONCLUSIONS

This study suggests that initial use of ET epinephrine is reasonable during DR resuscitation, as there were greater rates of ROSC compared with initial IV epinephrine administration. However, administration of IV epinephrine should not be delayed in those infants not responding to initial ET epinephrine, as almost one-half of infants who received initial ET epinephrine subsequently received IV epinephrine before achieving ROSC.

Sustained inflation and chest compression versus 3:1 chest compression to ventilation ratio during cardiopulmonary resuscitation of asphyxiated newborns (SURV1VE): A cluster randomised controlled trial

OBJECTIVE

In newborn infants requiring chest compression (CC) in the delivery room (DR) does continuous CC superimposed by a sustained inflation (CC+SI) compared with a 3:1 compression:ventilation (3:1 C:V) ratio decreases time to return of spontaneous circulation (ROSC).

DESIGN

International, multicenter, prospective, cluster cross-over randomised trial.

SETTING

DR in four hospitals in Canada and Austria, PARTICIPANTS: Newborn infants >28 weeks' gestation who required CC.

INTERVENTIONS

Hospitals were randomised to CC+SI or 3:1 C:V then crossed over to the other intervention.

MAIN OUTCOME MEASURE

The primary outcome was time to ROSC, defined as the duration of CC until an increase in heart rate >60/min determined by auscultation of the heart, which was maintained for 60 s. Sample size of 218 infants (109/group) was sufficient to detect a clinically important 33% reduction (282 vs 420 s of CC) in time to ROSC. Analysis was intention-to-treat.

RESULTS

Patient recruitment occurred between 19 October 2017 and 22 September 2022 and randomised 27 infants (CC+SI (n=12), 3:1 C:V (n=15), two (one per group) declined consent). All 11 infants in the CC+SI group and 12/14 infants in the 3:1 C:V group achieved ROSC in the DR. The median (IQR) time to ROSC was 90 (60-270) s and 615 (174-780) s (p=0.0502 (log rank), p=0.16 (cox proportional hazards regression)) with CC+SI and 3:1 C:V, respectively. Mortality was 2/11 (18.2%) with CC+SI versus 8/14 (57.1%) with 3:1 C:V (p=0.10 (Fisher's exact test), OR (95% CI) 0.17; (0.03 to 1.07)). The trial was stopped due to issues with ethics approval and securing trial insurance as well as funding reasons.

CONCLUSION

The time to ROSC and mortality was not statistical different between CC+SI and 3:1 C:V.

A Novel Method for Administering Epinephrine during Neonatal Resuscitation

OBJECTIVE

This study aimed to determine if prefilled epinephrine syringes will reduce time to epinephrine administration compared with conventional epinephrine during standardized simulated neonatal resuscitation.

STUDY DESIGN

Timely and accurate epinephrine administration during neonatal resuscitation is lifesaving in bradycardic infants. Current epinephrine preparation is inefficient and error-prone. For other emergency use drugs, prefilled medication syringes have decreased error and administration time. Twenty-one neonatal intensive care unit nurses were enrolled. Each subject engaged in four simulated neonatal resuscitation scenarios involving term or preterm manikins using conventional epinephrine or novel prefilled epinephrine syringes specified for patient weight and administration route. All scenarios were video-recorded. Two investigators analyzed video recordings for time to epinephrine preparation and administration. Differences between conventional and novel techniques were evaluated using the Wilcoxon Signed Rank Tests.

RESULTS

Twenty-one subjects completed 42 scenarios with conventional epinephrine and 42 scenarios with novel prefilled syringes. Epinephrine preparation was faster using novel prefilled epinephrine syringes (median = 17.0 s, interquartile range [IQR] = 13.3-22.8) compared with conventional epinephrine (median = 48.0 s, IQR = 40.5-54.9, n = 42, z = 5.64, p < 0.001). Epinephrine administration was also faster using novel prefilled epinephrine syringes (median = 26.9 s, IQR = 22.1-33.2) compared with conventional epinephrine (median = 57.6 s, IQR = 48.8-66.8, n = 42, z = 5.63, p < 0.001). In a poststudy survey, all subjects supported the clinical adoption of prefilled epinephrine syringes.

CONCLUSION

During simulated neonatal resuscitation, epinephrine preparation and administration are faster using novel prefilled epinephrine syringes, which may hasten return of spontaneous circulation and be lifesaving for bradycardic neonates in clinical practice.

KEY POINTS

· Currently, epinephrine administration in neonatal resuscitation is inefficient and error prone.. · Prefilled epinephrine syringes hasten medication administration in simulated neonatal resuscitation.. · Clinical use of prefilled epinephrine syringes may be lifesaving for bradycardic neonates..

Identifying Gaps in Resuscitation Practices Across Level-IV Neonatal Intensive Care Units

OBJECTIVES

This study aimed to describe resuscitation practices in level-IV neonatal intensive care units (NICUs) and identify possible areas of improvement.

STUDY DESIGN

This study was a cross-sectional cohort survey and conducted at the Level-IV NICUs of Children's Hospital Neonatal Consortium (CHNC). The survey was developed with consensus from resuscitation and education experts in the CHNC and pilot tested. An electronic survey was sent to individual site sponsors to determine unit demographics, resuscitation team composition, and resuscitation-related clinical practices.

RESULTS

Of the sites surveyed, 33 of 34 sites responded. Unit average daily census ranged from less than 30 to greater than 100, with the majority (72%) of the sites between 30 and 75 patients. A designated code response team was utilized in 18% of NICUs, only 30% assigned roles before or during codes. The Neonatal Resuscitation Program (NRP) was the exclusive algorithm used during codes in 61% of NICUs, and 34% used a combination of NRP and the Pediatric Advanced Life Support (PALS). Most (81%) of the sites required neonatal attendings to maintain NRP training. A third of sites (36%) lacked protocols for high-acuity events. A code review process existed in 76% of participating NICUs, but only 9% of centers enter code data into a national database.

CONCLUSION

There is variability among units regarding designated code team presence and composition, resuscitation algorithm, protocols for high-acuity events, and event review. These inconsistencies in resuscitation teams and practices provide an opportunity for standardization and, ultimately, improved resuscitation performance. Resources, education, and efforts could be directed to these areas to potentially impact future neonatal outcomes of the complex patients cared for in level-IV NICUs.

KEY POINTS

· Resuscitation practice is variable in level-IV NICUs.. · Resuscitation algorithm training is not uniform. · Standardized protocols for high-acuity low-occurrence (HALO) events are lacking.

Endotracheal epinephrine at standard versus high dose for resuscitation of asystolic newborn lambs

INTRODUCTION

Endotracheal (ET) epinephrine administration is an option during neonatal resuscitation, if the preferred intravenous (IV) route is unavailable.

OBJECTIVES

We assessed whether endotracheal epinephrine achieved return of spontaneous circulation (ROSC), and maintained physiological stability after ROSC, at standard and higher dose, in severely asphyxiated newborn lambs.

METHODS

Near-term fetal lambs were asphyxiated until asystole. Resuscitation was commenced with ventilation and chest compressions. Lambs were randomly allocated to: IV Saline placebo (5 ml/kg), IV Epinephrine (20 micrograms/kg), Standard-dose ET Epinephrine (100 micrograms/kg), and High-dose ET Epinephrine (1 mg/kg). After three allocated treatment doses, rescue IV Epinephrine was administered if ROSC had not occurred. Lambs achieving ROSC were monitored for 60 minutes. Brain histology was assessed for microbleeds.

RESULTS

ROSC in response to allocated treatment (without rescue IV Epinephrine) occurred in 1/6 Saline, 9/9 IV Epinephrine, 0/9 Standard-dose ET Epinephrine, and 7/9 High-dose ET Epinephrine lambs respectively. Blood pressure during CPR increased after treatment with IV Epinephrine and High-dose ET Epinephrine, but not Saline or Standard-dose ET Epinephrine. After ROSC, both ET Epinephrine groups had lower pH, higher lactate, and higher blood pressure than the IV Epinephrine group. Cortex microbleeds were more frequent in High-dose ET Epinephrine lambs (8/8 lambs examined, versus 3/8 in IV Epinephrine lambs).

CONCLUSIONS

The currently recommended dose of ET Epinephrine was ineffective in achieving ROSC. Without convincing clinical or preclinical evidence of efficacy, use of ET Epinephrine at this dose may not be appropriate. High-dose ET Epinephrine requires further evaluation before clinical translation.

Direct Umbilical Vein Injection of Epinephrine with Cut-Cord Milking in an Ovine Model of Neonatal Resuscitation

BACKGROUND

An umbilical venous catheter (UVC) is the preferred route of epinephrine administration during neonatal resuscitation but requires specialized equipment, expertise, and time.

HYPOTHESIS

Direct injection of epinephrine into the umbilical vein (UV) followed by milking a ~20 cm segment of cut umbilical cord to flush the epinephrine (DUV + UCM) will lead to a quicker administration and earlier return of spontaneous circulation (ROSC) compared with epinephrine given through a UVC.

DESIGN

Eighteen near-term asphyxiated lambs were randomized to receive a low-UVC or DUV + UCM of epinephrine at 0.02 or 0.03 mg/kg doses.

OUTCOME MEASURES

A total of 16/18 lambs achieved ROSC with a similar mean (±SEM) time to ROSC [DUV + UCM vs. low-UVC (4.67 ± 0.67 vs. 3.99 ± 0.58 min); p = 0.46]. Two out of ten lambs in the DUV + UCM group required UVC placement for additional epinephrine. The administration of the first dose of epinephrine was similar (DUV + UCM-2.97 ± 0.48 vs. UVC-4.23 ± 0.58 min; p = 0.12). Both methods yielded similar epinephrine concentrations (peak concentrations of 253 ± 63 and 328 ± 80 ng/mL for DUV + UCM and UVC EPI, respectively).

CONCLUSIONS

DUV + UCM resulted in a ROSC success of 78% following the first epinephrine dose and showed similar epinephrine concentrations to UVC. Clinical studies evaluating DUV + UCM as an alternate route for epinephrine while intravenous access is being established are warranted.

Newborn resuscitation timelines: Accurately capturing treatment in the delivery room

OBJECTIVES

To evaluate the use of newborn resuscitation timelines to assess the incidence, sequence, timing, duration of and response to resuscitative interventions.

METHODS

A population-based observational study conducted June 2019-November 2021 at Stavanger University Hospital, Norway. Parents consented to participation antenatally. Newborns ≥28 weeks' gestation receiving positive pressure ventilation (PPV) at birth were enrolled. Time of birth was registered. Dry-electrode electrocardiogram was applied as soon as possible after birth and used to measure heart rate continuously during resuscitation. Newborn resuscitation timelines were generated from analysis of video recordings.

RESULTS

Of 7466 newborns ≥28 weeks' gestation, 289 (3.9%) received PPV. Of these, 182 had the resuscitation captured on video, and were included. Two-thirds were apnoeic, and one-third were breathing ineffectively at the commencement of PPV. PPV was started at median (quartiles) 72 (44, 141) seconds after birth and continued for 135 (68, 236) seconds. The ventilation fraction, defined as the proportion of time from first to last inflation during which PPV was provided, was 85%. Interruption in ventilation was most frequently caused by mask repositioning and auscultation. Suctioning was performed in 35% of newborns, in 95% of cases after the initiation of PPV. PPV was commenced within 60 s of birth in 49% of apnoeic and 12% of ineffectively breathing newborns, respectively.

CONCLUSIONS

Newborn resuscitation timelines can graphically present accurate, time-sensitive and complex data from resuscitations synchronised in time. Timelines can be used to enhance understanding of resuscitation events in data-guided quality improvement initiatives.

Effects of Endotracheal Epinephrine on Pharmacokinetics and Survival in a Swine Pediatric Cardiac Arrest Model

OBJECTIVES

The aim of this study was to compare the endotracheal tube (ET) and intravenous (IV) administration of epinephrine relative to concentration maximum, time to maximum concentration, mean concentration over time (MC), area under the curve, odds, and time to return of spontaneous circulation (ROSC) in a normovolemic pediatric cardiac arrest model.

METHODS

Male swine weighing 24-37 kg were assigned to 4 groups: ET (n = 8), IV (n = 7), cardiopulmonary resuscitation (CPR) + defibrillation (CPR + Defib) (n = 5), and CPR only (n = 3). Swine were placed arrest for 2 minutes, and then CPR was initiated for 2 minutes. Epinephrine (0.1 mg/kg) for the ET group or 0.01 mg/kg for the IV was administered every 4 minutes or until ROSC. Defibrillation started at 3 minutes and continued every 2 minutes for 30 minutes or until ROSC for all groups except the CPR-only group. Blood samples were collected over a period of 5 minutes.

RESULTS

The MC of plasma epinephrine for the IV group was significantly higher at the 30- and 60-second time points (P = 0.001). The ET group had a significantly higher MC of epinephrine at the 180- and 240-second time points (P < 0.05). The concentration maximum of plasma epinephrine was significantly lower for the ET group (195 ± 32 ng/mL) than for the IV group (428 ± 38 ng/mL) (P = 0.01). The time to maximum concentration was significantly longer for the ET group (145 ± 26 seconds) than for the IV group (42 ± 16 seconds) (P = 0.01). No significant difference existed in area under the curve between the 2 groups (P = 0.62). The odds of ROSC were 7.7 times greater for the ET versus IV group. Time to ROSC was not significantly different among the IV, ET, and CPR + Defib groups (P = 0.31).

CONCLUSIONS

Based on the results of this study, the ET route of administration should be considered a first-line intervention.

Considerations on the Use of Neonatal and Pediatric Resuscitation Guidelines for Hospitalized Neonates and Infants: On Behalf of the American Heart Association Emergency Cardiovascular Care Committee and the American Academy of Pediatrics

Between 0.25% and 3% of admissions to the NICU, PICU, and PCICU receive cardiopulmonary resuscitation (CPR). Most CPR events occur in patients <1 year old. The incidence of CPR is 10 times higher in the NICU than at birth. Therefore, optimizing the approach to CPR in hospitalized neonates and infants is important. At birth, the resuscitation of newborns is performed according to neonatal resuscitation guidelines. In older infants and children, resuscitation is performed according to pediatric resuscitation guidelines. Neonatal and pediatric guidelines differ in several important ways. There are no published recommendations to guide the transition from neonatal to pediatric guidelines. Therefore, hospitalized neonates and infants can be resuscitated using neonatal guidelines, pediatric guidelines, or a hybrid approach. This report summarizes the current neonatal and pediatric resuscitation guidelines, considers how to apply them to hospitalized neonates and infants, and identifies knowledge gaps and future priorities. The lack of strong scientific data makes it impossible to provide definitive recommendations on when to transition from neonatal to pediatric resuscitation guidelines. Therefore, it is up to health care teams and institutions to decide if neonatal or pediatric guidelines are the best choice in a given location or situation, considering local circumstances, health care team preferences, and resource limitations.

Vasopressin versus epinephrine during neonatal cardiopulmonary resuscitation of asphyxiated post-transitional piglets

Background

Epinephrine is currently the only recommended cardio-resuscitative medication for use in neonatal cardiopulmonary resuscitation (CPR), as per the consensus of science and treatment recommendations. An alternative medication, vasopressin, might be beneficial in neonatal CPR due to its combined pulmonary vasodilation and systemic vasoconstriction properties.

Aim

We aimed to compare the time to return of spontaneous circulation (ROSC) with administration of vasopressin or epinephrine during CPR of asphyxiated post-transitional piglets.

Methods

Newborn piglets (n = 8/group) were anesthetized, tracheotomized and intubated, instrumented, and exposed to 50 min normocapnic hypoxia followed by asphyxia and cardiac arrest. Piglets were randomly allocated to receive vasopressin (Vaso, 0.4 U/kg) or epinephrine (Epi, 0.02 mg/kg) during CPR. Piglets were resuscitated with chest compressions superimposed with sustained inflations, and were administered either Vaso or Epi intravenously every 3 min until ROSC (max. 3 doses). Hemodynamic and cardiac function parameters were collected.

Main Results

The median (IQR) time to ROSC was 106 (93-140) s with Vaso and 128 (100-198) s with Epi (p = 0.28). The number of piglets that achieved ROSC was 8 (100%) with Vaso and 7 (88%) with Epi (p = 1.00). Vaso-treated piglets had a significantly longer post-resuscitation survival time (240 (240-240) min) than Epi-treated piglets (65 (30-240) min, p = 0.02). Vaso-treated piglets had significantly improved carotid blood flow immediately after ROSC (p < 0.05), had longer duration of post-resuscitation hypertension (p = 0.05), and had significantly improved heart rate, arterial pressure, and cerebral blood oxygen saturation 4 h after ROSC (p < 0.05).

Conclusions

Vasopressin improved post-resuscitation survival and hemodynamics, and might be an alternative cardio-resuscitative medication during neonatal CPR, but further studies are warranted.

Chest compressions in newborn infants: a scoping review

AIM

The International Liaison Committee on Resuscitation Neonatal Life Support Task Force undertook a scoping review of the literature to identify evidence relating to neonatal cardiopulmonary resuscitation.

METHODS

MEDLINE complete, EMBASE and Cochrane database of Systematic reviews were searched from inception to November 2021. Two authors screened titles and abstracts and full text reviewed. Studies were eligible for inclusion if they were peer-reviewed and assessed one of five aspects of chest compression in the newborn infant including: (1) heart rate thresholds to start chest compressions (CC), (2) compression to ventilation ratio (C:V ratio), (3) CC technique, (4) oxygen use during CC and 5) feedback devices to optimise CC.

RESULTS

Seventy-four studies were included (n=46 simulation, n=24 animal and n=4 clinical studies); 22/74 were related to compression to ventilation ratios, 29/74 examined optimal technique to perform CC, 7/74 examined oxygen delivery and 15/74 described feedback devices during neonatal CC.

CONCLUSION

There were very few clinical studies and mostly manikin and animal studies. The findings either reinforced or were insufficient to change previous recommendations which included to start CC if heart rate remains <60/min despite adequate ventilation, using a 3:1 C:V ratio, the two-thumb encircling technique and 100% oxygen during CC.

Is epinephrine effective during neonatal resuscitation?

In the original research article published in Pediatric Research, Anderson et al provide valuable data from a placebo-controlled randomized trial on epinephrine in 12-hour-old piglets in cardiac arrest. In this commentary, we discuss briefly the existing evidence supporting use of epinephrine during neonatal resuscitation.

Chest compressions and medications during neonatal resuscitation

Prolonged resuscitation in neonates, although quite rare, may occur in response to profound intractable bradycardia as a result of asphyxia. In these instances, chest compressions and medications may be necessary to facilitate return of spontaneous circulation. While performing chest compressions, the two thumb method is preferred over the two finger technique, although several newer approaches are under investigation. While the ideal compression to ventilation ratio is still uncertain, a 3:1 ratio remains the recommendation by the Neonatal Resuscitation Program. Use of feedback mechanisms to optimize neonatal cardiopulmonary resuscitation (CPR) show promise and are currently under investigation. While performing optimal cardiac compressions to pump blood, use of medications to restore spontaneous circulation will likely be necessary. Current recommendations are that epinephrine, an endogenous catecholamine be used preferably intravenously or by intraosseous route, with the dose repeated every 3-5 minutes until return of spontaneous circulation. Finally, while the need for volume replacement is rare, it may be considered in instances of acute blood loss or poor response to resuscitation.

Special consideration in neonatal resuscitation

Delivery room resuscitation of neonates is performed according to evidence-based neonatal resuscitation guidelines. Neonatal resuscitation guidelines focus on the resuscitation of newborns suffering from perinatal asphyxia. Special considerations are needed when resuscitating newborns in locations other than the delivery room and for newborns with congenital anomalies. In this review, we examine the resuscitation of newborns at home and in the emergency department and highlight special considerations for resuscitating newborns with specific congenital anomalies. In addition, we explore the resuscitation of neonates in the neonatal intensive care unit and discuss the potential use of pediatric advanced life support guidelines. Finally, we highlight the importance of simulation to prepare teams for neonatal resuscitations. This review aims to prepare healthcare professionals in all disciplines caring for neonates at risk for requiring resuscitation under special circumstances.

Supraglottic Airways Compared With Face Masks for Neonatal Resuscitation: A Systematic Review

BACKGROUND AND OBJECTIVES

Positive pressure ventilation (PPV) is the most important component of neonatal resuscitation, but face mask ventilation can be difficult. Compare supraglottic airway devices (SA) with face masks for term and late preterm infants receiving PPV immediately after birth.

METHODS

Data sources include Medline, Embase, Cochrane Databases, Database of Abstracts of Reviews of Effects, and Cumulative Index to Nursing and Allied Health Literature. Study selections include randomized, quasi-randomized, interrupted time series, controlled before-after, and cohort studies with English abstracts. Two authors independently extracted data and assessed risk of bias and certainty of evidence. The primary outcome was failure to improve with positive pressure ventilation. When appropriate, data were pooled using fixed effect models.

RESULTS

Meta-analysis of 6 randomized controlled trials (1823 newborn infants) showed that use of an SA decreased the probability of failure to improve with PPV (relative risk 0.24; 95% confidence interval 0.17 to 0.36; P <.001, moderate certainty) and endotracheal intubation (4 randomized controlled trials, 1689 newborn infants) in the delivery room (relative risk 0.34, 95% confidence interval 0.20 to 0.56; P <.001, low certainty). The duration of PPV and time until heart rate >100 beats per minute was shorter with the SA. There was no difference in the use of chest compressions or epinephrine during resuscitation. Certainty of evidence was low or very low for most outcomes.

CONCLUSIONS

Among late preterm and term infants who require resuscitation after birth, ventilation may be more effective if delivered by SA rather than face mask and may reduce the need for endotracheal intubation.

Variation and Temporal Trends in Delivery Room Management of Moderate and Late Preterm Infants

BACKGROUND

Although delivery room (DR) intervention decreases with increasing gestational age (GA), little is known about DR management of moderate and late preterm (MLP) infants.

METHODS

Using the Vermont Oxford Network database of all NICU admissions, we examined the receipt of DR interventions including supplemental oxygen, positive pressure ventilation, continuous positive airway pressure, endotracheal tube ventilation, chest compressions, epinephrine, and surfactant among MLP infants (30 to 36 weeks') without congenital anomalies born from 2011 to 2020. Pneumothorax was examined as a potential resuscitation-associated complication. Intervention frequency was assessed at the infant- and hospital-level, stratified by GA and over time.

RESULTS

Overall, 55.3% of 616 110 infants (median GA: 34 weeks) from 483 Vermont Oxford Network centers received any DR intervention. Any DR intervention frequency decreased from 89.7% at 30 weeks to 44.2% at 36 weeks. From 2011 to 2020, there was an increase in the provision of continuous positive airway pressure (17.9% to 47.8%, P ≤.001) and positive pressure ventilation (22.9% to 24.9%, P ≤.001) and a decrease in endotracheal tube ventilation (6.9% to 4.0% P ≤.001), surfactant administration (3.5% to 1.3%, P ≤.001), and pneumothorax (1.9% to 1.6%, P ≤.001). Hospital rates of any DR intervention varied (median 54%, interquartile range 47% to 62%), though the frequency was similar across hospitals with different NICU capabilities after adjustment.

CONCLUSIONS

The DR management of MLP infants varies at the individual- and hospital-level and is changing over time. These findings illustrate the differing interpretation of resuscitation guidelines and emphasize the need to study MLP infants to improve evidence-based DR care.

Versorgung und Reanimation des reifen Neugeborenen nach der Geburt

Die volle Reanimation eines Neugeborenen mit Beatmungen, Thoraxkompressionen und der Gabe von Medikamenten ist ein äußerst seltenes Ereignis, das selbst neonatologische Teams immer wieder vor Herausforderungen stellt. Gerade in diesen seltenen und häufig dramatischen Situationen ist schnelles und umsichtiges Handeln im Team gefragt. Dabei ist die effektivste und meist einzig notwendige Maßnahme für die erfolgreiche Versorgung eines nicht spontan atmenden Neugeborenen eine suffiziente Maskenbeatmung. Wird diese effektiv durchgeführt, sind beim Neugeborenen in den seltensten Fällen tatsächlich Thoraxkompressionen notwendig. Im März 2021 wurde vom European Resuscitation Council (ERC) die neue Leitlinie zur Reanimation von Neugeborenen publiziert. Auf Basis dieser Leitlinie beschreibt der vorliegende Beitrag detailliert den im Algorithmus der Versorgung und Reanimation von reifen Neugeborenen dargestellten Handlungsablauf. Er richtet sich damit einerseits insbesondere an NichtneonatologInnen, die für die Versorgung v. a. von reifen Neugeborenen nach der Geburt verantwortlich sind. Andererseits soll er auch jenen zur Unterstützung dienen, die medizinisches Personal in der Versorgung von lebensbedrohten Neugeborenen trainieren und den Algorithmus der Neugeborenenreanimation als didaktisches Konzept vermitteln.

Assessment of optimal chest compression depth during neonatal cardiopulmonary resuscitation: a randomised controlled animal trial

AIM

The study aimed to examine the optimal anterior-posterior depth which will reduce the time to return of spontaneous circulation and improve survival during chest compressions. Asphyxiated neonatal piglets receiving chest compression resuscitated with a 40% anterior-posterior chest depth compared with 33%, 25% or 12.5% will have reduced time to return of spontaneous circulation and improved survival.

METHODS

Newborn piglets (n=8 per group) were anaesthetised, intubated, instrumented and exposed to 45 min normocapnic hypoxia followed by asphyxia and cardiac arrest. Piglets were randomly allocated to four intervention groups ('anterior-posterior 12.5% depth', 'anterior-posterior 25% depth', 'anterior-posterior 33% depth' or 'anterior-posterior 40% depth'). Chest compressions were performed using an automated chest compression machine with a rate of 90 per minute. Haemodynamic and respiratory parameters, applied compression force, and chest compression depth were continuously measured.

RESULTS

The median (IQR) time to return of spontaneous circulation was 600 (600-600) s, 135 (90-589) s, 85 (71-158)* s and 116 (63-173)* s for the 12.5%, 25%, 33% and 40% depth groups, respectively (*p<0.001 vs 12.5%). The number of piglets that achieved return of spontaneous circulation was 0 (0%), 6 (75%), 7 (88%) and 7 (88%) in the 12.5%, 25%, 33% and 40% anterior-posterior depth groups, respectively. Arterial blood pressure, central venous pressure, carotid blood flow, applied compression force, tidal volume and minute ventilation increased with greater anterior-posterior chest depth during chest compression.

CONCLUSIONS

Time to return of spontaneous circulation and survival were similar between 25%, 33% and 40% anterior-posterior depths, while 12.5% anterior-posterior depth did not result in return of spontaneous circulation or survival. Haemodynamic and respiratory parameters improved with increasing anterior-posterior depth, suggesting improved organ perfusion and oxygen delivery with 33%-40% anterior-posterior depth.

Comparison of intraosseous and intravenous epinephrine administration during resuscitation of asphyxiated newborn lambs

OBJECTIVE

Intraosseous access is recommended as a reasonable alternative for vascular access during newborn resuscitation if umbilical access is unavailable, but there are minimal reported data in newborns. We compared intraosseous with intravenous epinephrine administration during resuscitation of severely asphyxiated lambs at birth.

METHODS

Near-term lambs (139 days' gestation) were instrumented antenatally for measurement of carotid and pulmonary blood flow and systemic blood pressure. Intrapartum asphyxia was induced by umbilical cord clamping until asystole. Resuscitation commenced with positive pressure ventilation followed by chest compressions and the lambs received either intraosseous or central intravenous epinephrine (10 μg/kg); epinephrine administration was repeated every 3 min until return of spontaneous circulation (ROSC). The lambs were maintained for 30 min after ROSC. Plasma epinephrine levels were measured before cord clamping, at end asphyxia, and at 3 and 15 min post-ROSC.

RESULTS

ROSC was successful in 7 of 9 intraosseous epinephrine lambs and in 10 of 12 intravenous epinephrine lambs. The time and number of epinephrine doses required to achieve ROSC were similar between the groups, as were the achieved plasma epinephrine levels. Lambs in both groups displayed a similar marked overshoot in systemic blood pressure and carotid blood flow after ROSC. Blood gas parameters improved more quickly in the intraosseous lambs in the first 3 min, but were otherwise similar over the 30 min after ROSC.

CONCLUSIONS

Intraosseous epinephrine administration results in similar outcomes to intravenous epinephrine during resuscitation of asphyxiated newborn lambs. These findings support the inclusion of intraosseous access as a route for epinephrine administration in current guidelines.

The effect of neonatal resuscitation training based on a serious game simulation method on nursing students' knowledge, skills, satisfaction and self-confidence levels: A randomized controlled trial

BACKGROUND

Although students are well prepared theoretically, they lack real-life practical skills because they have not faced an adequate number of emergencies such as neonatal resuscitation.

OBJECTIVES

This study was conducted with the objective of determining the impact of integrating serious game simulation (SGS) into neonatal resuscitation training on the neonatal resuscitation related knowledge, skills, satisfaction with training, and self confidence in learning of nursing students.

DESIGN

The study is a randomized controlled, pre-test post-test design and single-blind study.

SETTINGS AND PARTICIPANTS

This study was conducted on 90 undergraduate nursing students (SGS based training group = 45, control group = 45) enrolled in the fifth semester at the Faculty of Nursing.

METHODS

The students were allocated with simple randomization method to intervention and control groups. The training program prepared on the basis of neonatal resuscitation algorithm used a neonatal resuscitation serious game simulation method. At the same time, the serious game simulation method was used as a pre-test and post-test skill assessment tool. Support was obtained from a statistician in evaluation of the data and the data were analyzed using the SPSS (Statistical Package for Social Sciences) for Windows 25.0 program.

RESULTS

Post-test measurements indicated a statistically significant positive difference in the ventilation and chest compression performing skills of the intervention group compared to the control group (p = .011, p = .020, respectively). A considerable increase was found in the knowledge and skills level of both groups, after the neonatal resuscitation training (p < .05). The score averages of the Student Satisfaction and Self-Confidence in Learning Scale and its sub-dimensions were high for both groups.

CONCLUSIONS

It was concluded that the serious game simulation application used in neonatal resuscitation training was effective in raising the students' ventilation and compression performing skills.

Recent Update on Neonatal Resuscitation

Every 5 y, the International Liaison Committee on Resuscitation publishes consensus on cardiopulmonary resuscitation, and emergency cardiovascular science and treatment recommendations. The latest update on neonatal resuscitation guidelines was published in 2020. Here, the authors review the important changes in the recent recommendations, including initial steps of resuscitation, umbilical cord management, management of nonvigorous infants born through meconium-stained amniotic fluid, sustained inflation in preterm infants, epinephrine, vascular access, timing of discontinuation of resuscitative effort, and team briefing and debriefing.

Know the Code: Medications for Resuscitation in Neonates

Resuscitations in the delivery room or the nursery cause significant stress for caregivers. Diligent preparation will improve the efficacy and safety of life-saving interventions and increase staff comfort. When establishment of an airway and delivery of positive pressure ventilation and chest compressions fail to result in return of spontaneous circulation, pharmacotherapeutic interventions should be considered. Epinephrine is first-line pharmacotherapy for severe bradycardia or cardiac arrest, increasing coronary arterial pressure and blood flow during chest compressions. Despite limited data regarding dosing and efficacy, the first dose of epinephrine may be delivered through the endotracheal tube during attainment of venous access (preferably a low-lying umbilical venous catheter in the delivery room). Intravenous dosing is preferred, and any facility caring for newborns must ensure optimized logistics including readily available dosing guidance and optimal flush volumes. After provision of epinephrine, additional medications may be considered, especially for resuscitations occurring outside of the immediate perinatal period, including normal saline, glucose, adenosine, atropine, and calcium. Clinicians must understand the indications, dosing, and monitoring parameters for these medications and ensure rapid availability for resuscitation. Every second truly counts in a neonatal resuscitation, and optimal understanding and preparation will ensure delivery of pharmacotherapy to optimize both patient outcomes and staff comfort.

Assessing Implementation of Helping Babies Breathe Program Through Observing Immediate Care of Neonates at Time of Delivery

BACKGROUND

Training in neonatal resuscitation has been shown to reduce deaths related to intrapartum asphyxia. Helping Babies Breathe (HBB) is a simulation-based program focusing on training healthcare providers (HCPs) in immediate neonatal care including stimulation, initiating bag mask ventilation (BMV) in the absence of breathing by 1 min of life, and delayed (30-60 s after birth) umbilical cord clamping (DCC). Data on implementation of HBB posttraining are limited.

OBJECTIVE

To determine time from birth to spontaneous breathing, cord clamping, and initiation of BMV in a setting where the majority of HCPs are HBB trained.

METHODS

Two research nurses observed deliveries conducted in two referral hospitals. Timing included the onset of breathing, cord clamping, and initiation of BMV. Deliveries were grouped according to the mode of delivery.

RESULTS

In total, 496 neonates were observed; 410 (82.7%) neonates cried or had spontaneous breathing (median time 17 s) soon after birth, 25/86 (29%) of neonates not breathing responded to stimulation, 61 (12.3%) neonates required BMV, and 2 (0.4%) neonates required chest compression and/or adrenalin. Neonates delivered by cesarean section (CS) took longer to initiate first breath than those delivered vaginally (median time 19 vs. 14 s; p = 0.009). Complete data were available in 58/61 (95%) neonates receiving BMV, which was initiated in 54/58 (93%) cases within 60 s of life (the "Golden Minute"). Median time to cord clamping was 74 s, with 414 (83.5%) and 313 (63.0%) having cord clamped at ≥ 30 and ≥ 60 s, respectively. Factors associated with BMV were CS delivery [odds ratio (OR) 29.9; 95% CI 3.37-229], low birth weight (LBW) (birthweight < 2,500 g) (OR 2.47; 95% CI 1.93-5.91), and 1 min Apgar score < 7 (OR 149; 95% CI 49.3-5,021). DCC (≥ 60 s) was less likely following CS delivery (OR 0.14; 95% CI 0.02-0.99) and being LBW (OR 0.43; 95% CI 0.24-0.77).

CONCLUSION

Approximately 83% of neonates initiated spontaneous breathing soon after birth and 29% of neonates not breathing responded to physical stimulation. BMV was initiated within the Golden Minute in most neonates, but under two-thirds had DCC (≥60 s). HBB implementation followed guidelines, suggesting that knowledge and skills taught from HBB are retained and applied by HCP.

Resuscitation 2020: Proceedings From the NeoHeart 2020 International Conference

Resuscitation guidelines are developed and revised by medical societies throughout the world. These guidelines are increasingly based on evidence from preclinical and clinical research. The International Liaison Committee on Resuscitation reviews evidence for each resuscitation practice and provides summary consensus statements that inform resuscitation guideline committees. A similar process is used for different populations including neonatal, pediatric, and adult resuscitation. The NeoHeart 2020 Conference brought together experts in resuscitation to discuss recent evidence and guidelines for resuscitation practices. This review summarizes the main focus of discussion from this symposium.

Randomised trial of epinephrine dose and flush volume in term newborn lambs

OBJECTIVES

Neonatal resuscitation guidelines recommend 0.5-1 mL saline flush following 0.01-0.03 mg/kg of epinephrine via low umbilical venous catheter for persistent bradycardia despite effective positive pressure ventilation (PPV) and chest compressions (CC). We evaluated the effects of 1 mL vs 3 mL/kg flush volumes and 0.01 vs 0.03 mg/kg doses on return of spontaneous circulation (ROSC) and epinephrine pharmacokinetics in lambs with cardiac arrest.

DESIGN

Forty term lambs in cardiac arrest were randomised to receive 0.01 or 0.03 mg/kg epinephrine followed by 1 mL or 3 mL/kg flush after effective PPV and CC. Epinephrine (with 1 mL flush) was repeated every 3 min until ROSC or until 20 min. Haemodynamics, blood gases and plasma epinephrine concentrations were monitored.

RESULTS

Ten lambs had ROSC before epinephrine administration and 2 died during instrumentation. Among 28 lambs that received epinephrine, 2/6 in 0.01 mg/kg-1 mL flush, 3/6 in 0.01 mg/kg-3 mL/kg flush, 5/7 in 0.03 mg/kg-1 mL flush and 9/9 in 0.03 mg/kg-3 mL/kg flush achieved ROSC (p=0.02). ROSC was five times faster with 0.03 mg/kg epinephrine compared with 0.01 mg/kg (adjusted HR (95% CI) 5.08 (1.7 to 15.25)) and three times faster with 3 mL/kg flush compared with 1 mL flush (3.5 (1.27 to 9.71)). Plasma epinephrine concentrations were higher with 0.01 mg/kg-3 mL/kg flush (adjusted geometric mean ratio 6.0 (1.4 to 25.7)), 0.03 mg/kg-1 mL flush (11.3 (2.1 to 60.3)) and 0.03 mg/kg-3 mL/kg flush (11.0 (2.2 to 55.3)) compared with 0.01 mg/kg-1 mL flush.

CONCLUSIONS

0.03 mg/kg epinephrine dose with 3 mL/kg flush volume is associated with the highest ROSC rate, increases peak plasma epinephrine concentrations and hastens time to ROSC. Clinical trials evaluating optimal epinephrine dose and flush volume are warranted.

Singapore Neonatal Resuscitation Guidelines 2021

Neonatal resuscitation is a coordinated, team-based series of timed sequential steps that focuses on a transitional physiology to improve perinatal and neonatal outcomes. The practice of neonatal resuscitation has evolved over time and continues to be shaped by emerging evidence as well as key opinions. We present the revised Neonatal Resuscitation Guidelines for Singapore 2021. The recommendations from the International Liaison Committee on Resuscitation Neonatal Task Force Consensus on Science and Treatment Recommendations (2020) and guidelines from the American Heart Association and European Resuscitation Council were compared with existing guidelines. The recommendations of the Neonatal Subgroup of the Singapore Resuscitation and First Aid Council were derived after the work group discussed and appraised the current available evidence and their applicability to local clinical practice.

Evaluation of the proper chest compression depth for neonatal resuscitation using computed tomography: A retrospective study

This study was created to assess whether a 30-mm depth of chest compression (CC) is sufficient and safe for neonatal cardiopulmonary resuscitation.This retrospective analysis was performed with chest computed tomography scans of neonates in 2 hospitals between 2004 and 2018. We measured several chest parameters and calculated heart compression fraction (HCF) using the ejection fraction formula. We evaluated whether one-third of the external anterior-posterior (AP) diameter and HCF with them are the equivalent to 25-, 30-, 35 mm and HCF with them, respectively, and the number of individuals with over-compression (internal chest AP diameter - compressed depth <10 mm) to estimate a safe CC depth. We divided the patients into term and preterm groups and compared their outcomes.In total, 63 of the 75 included individuals were analyzed, and one-third of the external lengths was equivalent to 30 ± 3 mm (P < .001). When the patients were divided into term (n = 53) and preterm (n = 10) groups, the equivalent depth was 30 ± 3 mm in the term group (P < .001) and 25 ± 2.5 mm in the preterm group (P = .004). The HCF with 30 mm was equivalent to that for one-third of the external length (P < .001). When we simulated CCs with a 30-mm depth, over-compression occurred more frequently in the preterm group (20%) compared to the term group (1.9%) (P = .014).A 30-mm depth could be appropriate for sufficient and safe neonatal resuscitation. Shallower CC should be considered in preterm babies.

Self-directed video versus instructor-based neonatal resuscitation training: a randomized controlled blinded non-inferiority multicenter international study

OBJECTIVE

To compare the efficacy of video-assisted self-directed neonatal resuscitation skills course with video-assisted facilitator-led course.

METHODS

This multicenter, randomized, blinded, non-inferiority-controlled trial compared two methods of teaching basic neonatal resuscitation skills using mask ventilation. Groups of novice providers watched an instructional video. One group received instructor facilitation (Ins-Video). The other group did not (Self-Video). An Objective Structured Clinical Exam (OSCE) measured skills performance, and a written test gauged knowledge.

RESULTS

One hundred and thirty-four students completed the study. Sixty-three of 68 in the Self-Video Group (92.6%) and 59 of 66 in the Ins-Video Group (89.4%) achieved post-training competency in positive pressure ventilation (primary outcome). OSCE passing rates were low in both groups. Knowledge survey scores were comparable between groups and non-inferior.

CONCLUSIONS

Video self-instruction taught novice providers positive pressure ventilation skills and theoretical knowledge, but it was insufficient for mastery of basic neonatal resuscitation in simulation environment.

What is the optimal initial dose of epinephrine during neonatal resuscitation in the delivery room?

The neonatal resuscitation program recommends a wide dose range of epinephrine for newborns who receive chest compressions (endotracheal tube [ET] dose of 0.05-0.1 mg/kg or intravenous [IV] dose of 0.01-0.03 mg/kg), which presents a challenge to neonatal care providers when attempting to determine the optimal initial dose. Dosing errors are common when preparing epinephrine for neonatal resuscitation. Based on animal data, we suggest preparing 0.1 mg/kg or 1 ml/kg of 1 mg/10 ml epinephrine in a 5 ml syringe for ET administration. For IV epinephrine, we suggest preparing an initial dose of 0.02 mg/kg or 0.2 ml/kg of 1 mg/10 ml epinephrine in a 1 ml syringe. A dose of 0.02 mg/kg enables use of a 1 ml syringe for a wide range of birth weights from 500 g to 5 kg. The use of a color-coded syringe may decrease errors in dose preparation.

Examining the Validity of Pediatric Resident Self-Assessment in the Delivery Room

OBJECTIVE

 The validity of resident self-assessment of competence in neonatal resuscitation skills has not been studied. This study was designed to test the hypothesis that residents are accurate in self-assessment of basic delivery room resuscitation and bag-and-mask ventilation (BMV) skills by comparing resident self-assessed performance with assessment by observers.

STUDY DESIGN

 We conducted a prospective repeated measures observational study. After each delivery residents and observers completed 13-question standardized assessments evaluating resident performance.

RESULTS

 A total of 99 paired assessments were completed by 36 residents. Residents competently performed and identified correct versus incorrect performance of basic resuscitation steps. Residents were less competent in recognizing the need for BMV and were unable to self-assess BMV-associated performance accurately. In multivariable analysis, only basic resuscitation steps versus BMV were significantly associated with accurate self-assessment.

CONCLUSION

 Pediatric residents are less competent at performing advanced neonatal resuscitation skills and are unable to accurately self-assess performance of skills essential for neonatal resuscitation.

KEY POINTS

· Pediatric residents can competently identify and perform basic neonatal resuscitation steps.. · Pediatric residents are less competent at performing advanced neonatal resuscitation skills.. · Self-assessment is not a valid method for determining resident competence in neonatal resuscitation..

2020 International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations

This 2020 International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations (CoSTR) for neonatal life support includes evidence from 7 systematic reviews, 3 scoping reviews, and 12 evidence updates. The Neonatal Life Support Task Force generally determined by consensus the type of evidence evaluation to perform; the topics for the evidence updates followed consultation with International Liaison Committee on Resuscitation member resuscitation councils. The 2020 CoSTRs for neonatal life support are published either as new statements or, if appropriate, reiterations of existing statements when the task force found they remained valid.Evidence review topics of particular interest include the use of suction in the presence of both clear and meconium-stained amniotic fluid, sustained inflations for initiation of positive-pressure ventilation, initial oxygen concentrations for initiation of resuscitation in both preterm and term infants, use of epinephrine (adrenaline) when ventilation and compressions fail to stabilize the newborn infant, appropriate routes of drug delivery during resuscitation, and consideration of when it is appropriate to redirect resuscitation efforts after significant efforts have failed.All sections of the Neonatal Resuscitation Algorithm are addressed, from preparation through to postresuscitation care. This document now forms the basis for ongoing evidence evaluation and reevaluation, which will be triggered as further evidence is published.Over 140 million babies are born annually worldwide (https://ourworldindata.org/grapher/births-and-deaths-projected-to-2100). If up to 5% receive positive-pressure ventilation, this evidence evaluation is relevant to more than 7 million newborn infants every year. However, in terms of early care of the newborn infant, some of the topics addressed are relevant to every single baby born.

Delivery Room Management of Asphyxiated Term and Near-Term Infants

Approximately 800,000 newborns die annually due to birth asphyxia. The resuscitation of asphyxiated term newly born infants often occurs unexpected and is challenging for healthcare providers as it demands experience and knowledge in neonatal resuscitation. Current neonatal resuscitation guidelines often focus on resuscitation of extremely and/or very preterm infants; however, the recommendations for asphyxiated term newborn infants differ in some aspects to those for preterm infants (i.e., respiratory support, supplemental oxygen, and temperature management). Since the update of the neonatal resuscitation guidelines in 2015, several studies examining various resuscitation approaches to improve the outcome of asphyxiated infants have been published. In this review, we discuss current recommendations and recent findings and provide an overview of delivery room management of asphyxiated term newborn infants.

Health Care Providers' Performance, Mindset, and Attitudes Toward a Neonatal Resuscitation Computer-Based Simulator: Empirical Study

BACKGROUND

Neonatal resuscitation involves a complex sequence of actions to establish an infant's cardiorespiratory function at birth. Many of these responses, which identify the best action sequence in each situation, are taught as part of the recurrent Neonatal Resuscitation Program training, but they have a low incidence in practice, which leaves health care providers (HCPs) less prepared to respond appropriately and efficiently when they do occur. Computer-based simulators are increasingly used to complement traditional training in medical education, especially in the COVID-19 pandemic era of mass transition to digital education. However, it is not known how learners' attitudes toward computer-based learning and assessment environments influence their performance.

OBJECTIVE

This study explores the relation between HCPs' attitudes toward a computer-based simulator and their performance in the computer-based simulator, RETAIN (REsuscitation TrAINing), to uncover the predictors of performance in computer-based simulation environments for neonatal resuscitation.

METHODS

Participants were 50 neonatal HCPs (45 females, 4 males, 1 not reported; 16 respiratory therapists, 33 registered nurses and nurse practitioners, and 1 physician) affiliated with a large university hospital. Participants completed a demographic presurvey before playing the game and an attitudinal postsurvey after completing the RETAIN game. Participants' survey responses were collected to measure attitudes toward the computer-based simulator, among other factors. Knowledge on neonatal resuscitation was assessed in each round of the game through increasingly difficult neonatal resuscitation scenarios. This study investigated the moderating role of mindset on the association between the perceived benefits of understanding the terminology used in the computer-based simulator, RETAIN, and their performance on the neonatal resuscitation tasks covered by RETAIN.

RESULTS

The results revealed that mindset moderated the relation between participants' perceived terminology used in RETAIN and their actual performance in the game (F3,44=4.56, R2=0.24, adjusted R2=0.19; P=.007; estimate=-1.19, SE=0.38, t44=-3.12, 95% CI -1.96 to -0.42; P=.003). Specifically, participants who perceived the terminology useful also performed better but only when endorsing more of a growth mindset; they also performed worse when endorsing more of a fixed mindset. Most participants reported that they enjoyed playing the game. The more the HCPs agreed that the terminology in the tutorial and in the game was accessible, the better they performed in the game, but only when they reported endorsing a growth mindset exceeding the average mindset of all the participants (F3,44=6.31, R2=0.30, adjusted R2=0.25; P=.001; estimate=-1.21, SE=0.38, t44=-3.16, 95% CI -1.99 to -0.44; P=.003).

CONCLUSIONS

Mindset moderates the strength of the relationship between HCPs' perception of the role that the terminology employed in a game simulator has on their performance and their actual performance in a computer-based simulator designed for neonatal resuscitation training. Implications of this research include the design and development of interactive learning environments that can support HCPs in performing better on neonatal resuscitation tasks.

Pharmacological Heart Failure Therapy in Children: Focus on Inotropic Support

Pediatric heart failure is a clinical syndrome, which needs to be distinctly defined and the pathophysiological consequences considered. Pharmacological treatment depends on the disease- and age-specific myocardial characteristics. Acute and chronic low cardiac output is the result of an inadequate heart rate (rhythm), myocardial contractility, preload and afterload, and also ventriculo-ventricular interaction, synchrony, atrio-ventricular and ventricular-arterial coupling. The treatment of choice is curing the cause of heart failure, if possible.Acute HF therapy is still based to the use of catecholamines and inodilators. The cornerstone of chronic HF treatment consists of blocking the endogenous, neuro-humoral axis, in particular the adrenergic and renin-angiotensin-aldosterone system.Before neprilysin inhibitors are used in young children, their potential side-effect for inducing Alzheimer disease needs to be clarified. The focus of the current review is put on the differential use of the inotropic drugs as epinephrine, norepinephrine, dopamine and dobutamine, and also the inodilators milrinone and levosimendan. Considering effects and side-effects of any cardiac stimulating treatment strategy, co-medication with ß-blockers, angiotensin converting inhibitors (ACEIs), angiotensin blockers (ARBs) and mineralocorticoid receptor antagonists (MRAs) is not a contradiction, but a senseful measure, even still during the acute inotropic treatment.Missing sophisticated clinical trials using accurate entry criteria and clinically relevant endpoints, there is especially in cardiovascular diagnosis and treatment of young children a compromise of evidence-based versus pathophysiology-based procedures. But based on the pharmacological and pathophysiological knowledge a hypothesis-driven individualized treatment is already currently possible and therefore indicated.

Trends in neonatal resuscitation patterns in Queensland, Australia - A 10-year retrospective cohort study

OBJECTIVES

To describe the frequency of neonatal resuscitation interventions implemented for newborn babies in the state of Queensland over a 10-year period and determine if these changes suggest adherence to changes in Australian guidelines.

STUDY DESIGN

A population-based retrospective cohort study utilising the Queensland Perinatal Data Collection dataset. All liveborn babies ≥23 + 0 weeks + days gestation born between 1 July 2007 and 30 June 2017 were included except those for whom resuscitation was not attempted and those babies <25 + 0 weeks for whom it was unsuccessful. Trends in resuscitation were demonstrated using Loess regression.

RESULTS

Of 618,589 eligible newborns,182,260 received any resuscitation manoeuvre (29.5%). The proportion receiving oxygen without assisted ventilation declined from 19.3% in 2007-08 to 5.6% in 2016-17. Upper airway suctioning also decreased. Assisted ventilation increased from 7.9% to 10.0% of all babies with the largest contribution from late preterm and term babies. The rate of endotracheal suctioning for meconium and the rate of narcotic antagonist use also declined. A greater proportion of babies received chest compressions (1.9-3.2 per 1000 babies) and adrenaline (epinephrine). Mortality decreased from 1.9 to 1.5 per 1000 babies in the cohort.

CONCLUSION

Ten-year trends showed reduced use of oxygen or upper airway suctioning without assisted ventilation, reduced intubation to suction meconium, reduced use of narcotic antagonists and greater use of assisted ventilation suggesting appropriate practice change in response to Australian neonatal resuscitation guidelines. The increase in the use of chest compressions and adrenaline was unexpected and the reasons for it are unclear.

Neonatal Life Support: 2020 International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations

This 2020 International Consensus on Cardiopulmonary Resuscitation and Emergency Cardiovascular Care Science With Treatment Recommendations (CoSTR) for neonatal life support includes evidence from 7 systematic reviews, 3 scoping reviews, and 12 evidence updates. The Neonatal Life Support Task Force generally determined by consensus the type of evidence evaluation to perform; the topics for the evidence updates followed consultation with International Liaison Committee on Resuscitation member resuscitation councils. The 2020 CoSTRs for neonatal life support are published either as new statements or, if appropriate, reiterations of existing statements when the task force found they remained valid. Evidence review topics of particular interest include the use of suction in the presence of both clear and meconium-stained amniotic fluid, sustained inflations for initiation of positive-pressure ventilation, initial oxygen concentrations for initiation of resuscitation in both preterm and term infants, use of epinephrine (adrenaline) when ventilation and compressions fail to stabilize the newborn infant, appropriate routes of drug delivery during resuscitation, and consideration of when it is appropriate to redirect resuscitation efforts after significant efforts have failed. All sections of the Neonatal Resuscitation Algorithm are addressed, from preparation through to postresuscitation care. This document now forms the basis for ongoing evidence evaluation and reevaluation, which will be triggered as further evidence is published.
