Brief resolved unexplained events: a new diagnosis, with implications for evaluation and management

Brief resolved unexplained events (BRUE) are concerning episodes of short duration (typically < 1 min) characterized by a change in breathing, consciousness, muscle tone (hyper- or hypotonia), and/or skin color (cyanosis or pallor). The episodes occur in a normal-appearing infant in the first year of life, self-resolve, and have no readily identifiable explanation for the cause of the event. Previously called apparent life-threatening events (ALTE), the term BRUE was first defined by the American Academy of Pediatrics (AAP) in 2016. The criteria for BRUE carry greater specificity compared to that of ALTE and additionally are indicative of a diagnosis of exclusion. While most patients with BRUE will have a benign clinical course, important etiologies, including airway, cardiac, gastrointestinal, genetic, infectious, neurologic, and traumatic conditions (including nonaccidental), must be carefully considered. A BRUE is classified as either lower- or higher-risk based on patient age, corrected gestational age, event duration, number of events, and performance of cardiopulmonary resuscitation at the scene. The AAP clinical practice guideline provides recommendations for the management of lower-risk BRUEs, advocating against routine admission, blood testing, and imaging for infants with these events, though a short period of observation and/or an electrocardiogram may be advisable. While guidance exists for higher-risk BRUE, more data are required to better identify proportions and risk factors for serious outcomes among these patients. Conclusion: BRUE is a diagnosis with greater specificity relative to prior definitions and is now a diagnosis of exclusion. Additional research is needed, particularly in the evaluation of higher-risk events. Recent data suggest that the AAP guidelines for the management of lower-risk infants can be safely implemented.This review article summarizes the history, definitional changes, current guideline recommendations, and future research needs for BRUE. What is Known: • BRUE, first described in 2016, is a diagnosis used to describe a well-appearing infant who presents with change in breathing, consciousness, muscle tone (hyper- or hypotonia), and/or skin color (cyanosis or pallor). • BRUE can be divided into higher- and lower-risk events. Guidelines have been published for lower-risk events, with expert recommendations for higher-risk BRUE. What is New: • BRUE carries a low rate of serious diagnoses (< 5%), with the most common representing seizures and airway abnormalities. • Prior BRUE events are associated with serious diagnoses and episode recurrence.

OBJECTIVES

The purpose of this literature review is to make recommendations regarding the first steps and care provided to the healthy newborn.

METHODS

Consultation of the Medline database, and of national and international guidelines.

RESULTS

The initial assessment of the newborn should quickly determine whether resuscitation is necessary or not. Any anomaly requires the help of the pediatrician (Consensus agreement). For a newborn with no cardiorespiratory adaptation, delayed cord clamping may be considered more as a physiological modality of delivery, which may help prevent iron deficiency in the first months of life, without deleterious effects for the child or his/her mother, apart from a slightly increased risk of neonatal jaundice (gradeC). In order to avoid separating a woman and her child, it is recommended to postpone routine postnatal procedures, to allow for skin-to-skin contact between the mother and the newborn, if she wishes, according to a defined/specified surveillance protocol (grade B). Breastfeeding should be encouraged, and supported, especially the first time (Consensus agreement). In the absence of suggestive clinical signs, aspiration of the upper airways and systematic verification of the permeability of posterior nasal apertures and of the esophagus are not recommended (Consensus agreement). The prevention of hemorrhagic disease of the newborn by the oral administration of vitamin K1 to all healthy term babies begins in the delivery room, preferably in the presence of the parents and after having obtained their consent (Consensus agreement).

CONCLUSION

Regarding the birth of a healthy newborn, it is strongly advised to avoid unnecessary technical actions and to favor the mother-child relationship in a safe environment.

Sudden unexpected postnatal collapse

This review of Sudden Unexpected Postnatal Collapse (SUPC) highlights the challenges in definition and nomenclature that currently exist. In comparing SUPC with Sudden Unexpected Death in Infancy (SUDI), the potentially avoidable nature of many SUPC is emphasised and the role of positioning and public awareness explored. The article focusses on the implementation of preventative strategies in the immediate postnatal period and the role of therapeutic hypothermia in ameliorating long term neurological injury.

The Baby Friendly Hospital Initiative and the ten steps for successful breastfeeding. a critical review of the literature

There is no doubt regarding the multiple benefits of breastfeeding for infants and society in general. Therefore, the World Health Organization (WHO) in a conjoint effort with United Nations International Children's Emergency Fund (UNICEF) developed the "Ten Steps to Successful Breastfeeding" in 1992, which became the backbone of the Baby Friendly Hospital Initiative (BFHI). Following this development, many hospitals and countries intensified their position towards creating a "breastfeeding oriented" practice. Over the past two decades, the interest increased in the BFHI and the Ten Steps. However, alongside the implementation of the initiative, extensive research continues to evaluate the benefits and dangers of the suggested practices. Hence, it is our intention to make a critical evaluation of the current BFHI and the Ten Steps recommendations in consideration of the importance of providing an evidence-based breastfeeding supported environment for our mothers and infants.

Neonatal Safety of Elective Family-Centered Caesarean Sections: A Cohort Study

BACKGROUND

Although little data are available concerning safety for newborns, family-centered caesarean sections (FCS) are increasingly implemented. With FCS mothers can see the delivery of their baby, followed by direct skin-to-skin contact. We evaluated the safety for newborns born with FCS in the Leiden University Medical Center (LUMC), where FCS was implemented in June 2014 for singleton pregnancies with a gestational age (GA) ≥38 weeks and without increased risks for respiratory morbidity.

METHODS

The incidence of respiratory pathology, unplanned admission, and hypothermia in infants born after FCS in LUMC were retrospectively reviewed and compared with a historical cohort of standard elective cesarean sections (CS).

RESULTS

From June 2014 to November 2015, 92 FCS were performed and compared to 71 standard CS in 2013. Incidence of respiratory morbidity, hypothermia, temperatures at arrival at the department, GA, and birth weight were comparable (ns). Unplanned admission occurred more often after FCS when compared to standard CS (21 vs 7%; p = 0.03), probably due to peripheral oxygen saturation (SpO₂) monitoring. There was no increase in respiratory pathology (8 vs 6%, ns). One-third of the babies were separated from their mother during or after FCS.

CONCLUSION

Unplanned neonatal admissions after elective CS increased after implementing FCS, without an increase in respiratory morbidity or hypothermia. SpO₂ monitoring might have a contribution. Separation from the mother occurred often.

Early sudden unexpected death in infancy (ESUDI)--three case reports and review of the literature

AIM

Early sudden unexpected death in infancy (ESUDI) is a rare cause of death occurring in newborns during the first hours of life. Our aim was to find additional data for the identification of risk factors and establishment of prevention strategies.

METHODS

We describe three cases of ESUDI and give an overview of the literature.

RESULTS

ESUDI was observed in term babies with normal birth weight after good postnatal adaptation within the first four hours of life. Maternal age was between 29 and 36 years, mothers were primiparous and of normal weight. All three events occurred during unobserved early skin-to-skin contact. Autopsy and post-mortem metabolic screening revealed no cause of death. A search of the MEDLINE and Web of Science (Thomson Reuters) databases brought to light 132 cases of ESUDI reported in the literature from 1985 to 2012. Concurrent with our observations, first parity and unobserved early skin-to-skin contact seem to be prime predictors of ESUDI. Other pre-described risk factors such as mode of delivery, birth weight, mother's age and body mass index were not seen in our patients.

CONCLUSION

Close observation during the first hours of life is essential and can be life-saving, especially during early skin-to-skin contact.

Sudden unexpected postnatal collapse of newborn infants: a review of cases, definitions, risks, and preventive measures

This study aimed to review available published reports concerning sudden unexpected postnatal collapse (SUPC) of apparently healthy infants within the first days of postnatal life, establish a structured presentation and delineate recommendations for preventive measures. All published reports of SUPC cases were retrospectively analyzed, and three not previously published SUPC cases at Karolinska University Hospital were detailed to exemplify the varying presentations and outcomes of SUPC. We found 398 published cases of SUPC occurring during first postnatal week. Estimated incidence of the SUPC of a presumably healthy infant after birth differs widely, ranging from 2.6 cases to 133 cases/100,000. However, definition, inclusion, and exclusion criteria vary substantially between reports. Our summary indicates that reported SUPC occurs more frequently than expected from recent surveys. About half of the infants die, and of the remaining survivors, half have neurological sequela. Of the 233 cases of sudden unexpected death described, no etiology was found in 153 cases. When a defined time for the SUPC event is described, approximately one third of reported events occur during the first 2 h, between 2 and 24 h and between 1 and 7 days after birth, respectively. Adequate education of caregivers and appropriate surveillance during the first days of newborns should enable us to save hundreds of lives.

Apparent life-threatening events in presumably healthy newborns during early skin-to-skin contact

The death or near death of a presumably healthy newborn in the delivery room is uncommon. We report here 6 cases of apparent life-threatening events (ALTEs) in the delivery room during the first 2 hours of life. In each case, the incident occurred in a healthy infant who was in a prone position on his or her mother's abdomen during early skin-to-skin contact. In most cases, the mother was primiparous, and in all cases the mother and infant were not observed during the initiation of skin-to-skin contact and breastfeeding. There are many benefits of early skin-to-skin contact and breastfeeding in the delivery room. However, in view of the risk of a rare but significant ALTE, we suggest that surveillance of newborns is needed. Although many ALTEs are apparently caused by obstruction, we suggest that a standardized investigational workup be performed after an ALTE.

Sudden deaths and severe apparent life-threatening events in term infants within 24 hours of birth

OBJECTIVE AND DESIGN

To determine the incidence of and possible risk factors for unexpected sudden infant deaths (SID) and severe apparent life-threatening events (S-ALTE) that occurred within 24 hours of birth. This was a monthly epidemiologic survey.

PATIENTS AND METHODS

Throughout 2009, every pediatric department in Germany was asked to report such cases of unexplained SID or S-ALTE in term infants after a good postnatal adaptation (10-minute Apgar score ≥ 8) to the Surveillance Unit for Rare Pediatric Conditions in Germany. The latter has a capture rate of > 95%. S-ALTE was defined as acute cyanosis/pallor and unconsciousness, requiring bagging, intubation and/or cardiac compressions. Hospitals that reported a case were asked to return an anonymized questionnaire and discharge letter as well as the autopsy protocol in SID cases.

RESULTS

Of 43 cases reported, 17 fulfilled entry criteria, yielding an incidence of 2.6 in 100 000 live births. There were 7 deaths (ie, 1.1/100 000); 6 of the 10 S-ALTE infants were neurologically abnormal at discharge. Twelve infants were found lying on their mother's chest or abdomen, or very close to and facing her. Nine events occurred in the first 2 hours after birth; 7, were only noticed by a health professional despite the mother being present and awake.

CONCLUSIONS

SID or S-ALTE may occur in the first 24 hours after birth, particularly within the first 2 hours. Events seem often related to a potentially asphyxiating position. Parents may be too fatigued or otherwise not able to assess their infant's condition correctly. Closer observation during these earliest hours seems warranted.

Life-threatening event during skin-to-skin contact in the delivery room

After an uncomplicated term delivery, a newborn infant experienced a life-threatening even a few minutes after being born. Few such events have been described before, they may be due to suffocation; minor changes in surveillance can probably prevent these potentially devastating events.

Very early neonatal apparent life-threatening events and sudden unexpected deaths: incidence and risk factors

AIM

To evaluate the incidence of neonatal apparent life-threatening events and sudden unexpected deaths during the first 2 h after birth.

METHODS

A prospective study was conducted over a 1-year period in all the maternities of the French region of Provence, Alpes, Côte d'Azur, which included all presumably healthy full-term neonates. Twenty-three previously published cases were also studied in order to identify possible risk factors.

RESULTS

Sixty two thousand nine hundred sixty-eight live births were recorded over the study period. There were two neonatal apparent life-threatening events and no neonatal sudden unexpected death. The overall rate of neonatal apparent life-threatening events and unexpected deaths was thus 0.032 per 1000 live births. Three potential risk factors were identified: skin-to-skin contact, primiparous mother and mother and baby alone in the delivery room.

CONCLUSION

A neonatal apparent life-threatening event or sudden unexpected death during the first 2 h of life is very uncommon. Skin-to-skin contact between mother and infant left alone in the delivery room may constitute the main risk situation. This must not lead to reconsider skin-to-skin contact that has been proven beneficial and seems per se almost safe, but must induce maternity staff to pay particular attention to a skin-to skin infant when left alone with its mother.
