Introduction of a Quality Improvement Bundle Is Associated with Reduced Exposure to Mechanical Ventilation in Very Preterm Infants

Combining activity and grimace scores reflects perinatal stability in infants <32 weeks gestational age

BACKGROUND

Over 95% of infants less than 32 weeks gestational age-very preterm infants (VPTI)-require cardiorespiratory support at birth. Clinical condition at birth is assessed by the Apgar score, but the precision and accuracy of activity and grimace has not been evaluated. We hypothesised activity and grimace could predict the level of cardiorespiratory support required for stabilisation.

METHODS

Two hundred twenty-nine videos of VPTI resuscitations at Monash Children's Hospital and The Royal Women's Hospital, Melbourne were evaluated, with 78 videos eligible for assessment. Activity and grimace were scored (0, 1, or 2) by seven consultant neonatologists, with inter-rater reliability assessed. Activity and grimace were correlated with the maximum level of cardiorespiratory support required for stabilisation.

RESULTS

Kendall's Coefficient of Concordance (W) showed strong interobserver agreement for activity (W = 0.644, p < 0.001) and grimace (W = 0.722, p < 0.001). Neither activity nor grimace independently predicted the level of cardiorespiratory support required. Combining activity and grimace showed non-vigorous infants (combined score <2) received more cardiorespiratory support than vigorous (combined score ≥ 2).

CONCLUSION

Scoring of activity and grimace was consistent between clinicians. Independently, activity and grimace did not correlate with perinatal stabilisation. Combined scoring showed non-vigorous infants had greater resuscitation requirements.

IMPACT

Our study evaluates the precision and accuracy of activity and grimace to predict perinatal stability, which has not been validated in infants <32 weeks gestational age. We found strong score agreement between assessors, indicating video review is a practical and precise method for grading of activity and grimace. Combined scoring to allow a dichotomous evaluation of infants as non-vigorous or vigorous showed the former group required greater cardiorespiratory support at birth.

Decreasing early invasive mechanical ventilation exposure in preterm infants: a quality improvement initiative

OBJECTIVE

To decrease invasive mechanical ventilation exposure in the neonatal intensive care unit (NICU) in the first week of life for preterm infants with the global aim of decreasing bronchopulmonary dysplasia (BPD).

METHODS

We created a quality improvement (QI) initiative to optimize early non-invasive respiratory support which launched in August 2021. Patients born at <32 weeks gestation and admitted to the NICU on non-invasive respiratory support were included.

RESULTS

Invasive mechanical ventilation exposure decreased from 38 to 25% with evidence of special cause variation beginning in August 2022. Infants born at ≥26 weeks were most impacted, with a 50% reduction, from 34 to 17%. While BPD rates decreased, there has not yet been evidence of special cause variation.

CONCLUSION

Invasive mechanical ventilation exposure for infants born at <32 weeks gestation decreased following the creation of a QI initiative focused on optimization and standardization of early non-invasive respiratory support.

Alternatives to neonatal intubation

Opportunities to learn and maintain competence in neonatal intubation have decreased. As many clinicians providing care to the newborn infant are not skilled in intubation, alternative strategies are critical. Most preterm infants breathe spontaneously, and require stabilisation rather than resuscitation at birth. Use of tactile stimulation, deferred cord clamping, and avoidance of hypoxia can help optimise breathing for these infants. Nasal devices appear a promising alternative to the face mask for early provision of respiratory support. In term and near-term infants, supraglottic airways may be the most effective initial approach to resuscitation. Use of supraglottic airways during resuscitation can be taught to a range of providers, and may reduce need for intubation. While face mask ventilation is an important skill, it is challenging to perform effectively. Identification of the best approach to training the use of these devices during neonatal resuscitation remains an important priority.

Quality improvement for neonatal resuscitation and delivery room care

Quality improvement has become a foundation of neonatal care. Structured approaches to improvement can standardize practices, improve teamwork, engage families, and improve outcomes. The delivery room presents a unique environment for quality improvement; optimal delivery room care requires advanced preparation, adequately trained providers, and carefully coordinated team dynamics. In this article, we examine quality improvement for neonatal resuscitation. We review the published literature, focusing on reports targeting admission hypothermia, delayed cord clamping, and initial respiratory support. We discuss specific challenges related to delivery room quality improvement, including small numbers, data collection, and lack of benchmarking, and potential strategies to address them including simulation, checklists, and state and national collaboratives. We examine how quality improvement can target equity in delivery room outcomes, and explore the impact of the COVID-19 pandemic on delivery room quality of care.

Toward greater nuance in delayed cord clamping

PURPOSE OF REVIEW

For over a decade, the International Liaison Committee on Resuscitation has recommended delayed cord clamping (DCC), but implementation has been variable due to lack of consensus on details of technique and concerns for risks in certain patient populations. This review summarizes recent literature on the benefits and risks of DCC in term and preterm infants and examines alternative approaches such as physiologic-based cord clamping or intact cord resuscitation (ICR) and umbilical cord milking (UCM).

RECENT FINDINGS

DCC improves hemoglobin/hematocrit among term infants and may promote improved neurodevelopment. In preterms, DCC improves survival compared to early cord clamping; however, UCM has been associated with severe intraventricular hemorrhage in extremely preterm infants. Infants of COVID-19 positive mothers, growth-restricted babies, multiples, and some infants with cardiopulmonary anomalies can also benefit from DCC. Large randomized trials of ICR will clarify safety and benefits in nonvigorous neonates. These have the potential to dramatically change the sequence of events during neonatal resuscitation.

SUMMARY

Umbilical cord management has moved beyond simple time-based comparisons to nuances of technique and application in vulnerable sub-populations. Ongoing research highlights the importance of an individualized approach that recognizes the physiologic equilibrium when ventilation is established before cord clamping.
