Parental participation during therapeutic hypothermia for neonatal hypoxic-ischemic encephalopathy

Parent-infant closeness and care practices during therapeutic hypothermia in Swedish neonatal intensive care units

OBJECTIVES

The aim of this study was to investigate care practices among Neonatal Intensive Care Units (NICU) providing Therapeutic hypothermia (TH), and more specific to investigate staff's experiences of parental participation, presence, and possibilities of being close with their infant during TH.

METHODS

A descriptive, qualitative, and quantitative study. All Swedish NICUs providing TH (n = 10) participated. Data were collected during January-April 2021 via a questionnaire followed by a semi-structured interview with the registered nurse and the neonatologist responsible for TH at each unit. Descriptive statistics were calculated, and a qualitative content analysis was performed.

RESULTS

All NICUs allowed parents unlimited stay with their infants and were keen to support parental presence, which was a prerequisite for promoting parent-infant closeness. Standardized routines regarding the infants' care space and course of action were described as time-efficient and staff-saving, which freed up time to focus on the families.

CONCLUSION

Standardized routines regarding the care space setup and the medical and caring approach, as well as the NICU environment and practices around the families, can promote or curb the possibilities of parent-infant closeness. Well-established care practices and good environmental conditions with flexibility regarding the family's needs are therefore required.

Practice Variations for Therapeutic Hypothermia in Neonates with Hypoxic-ischemic Encephalopathy: An International Survey

OBJECTIVE

To evaluate variations in management of therapeutic hypothermia (TH) for neonatal hypoxic-ischemic encephalopathy (HIE) among international clinical sites and to identify areas for harmonization.

STUDY DESIGN

An electronic survey was sent to Children's Hospitals Neonatal Consortium site sponsors, Canadian Neonatal Network site investigators, members of the Newborn Brain Society, and American Academy of Pediatrics Neonatology chiefs.

RESULTS

One hundred five sites responded, with most from high-income regions (n = 95). Groupings were adapted from the United Nations regional groups: US (n = 52 sites); Canada (n = 20); Western Europe and other states excluding Canada and US Group (WEOG, n = 18); and non-WEOG (central and eastern Europe, Asia, Africa, Latin America, and Caribbean, n = 15). Regional variations were seen in the eligibility criteria for TH, such as the minimum gestational age, grading of HIE severity, use of electroencephalography, and the frequency of providing TH for mild HIE. Active TH during transport varied among regions and was less likely in smaller volume sites. Amplitude-integrated electroencephalogram and/or continuous electroencephalogram to determine eligibility for TH was used by most sites in WEOG and non-WEOG but infrequently by the US and Canada Groups. For sedation during TH, morphine was most frequently used as first choice but there was relatively high (33%) use of dexmedetomidine in the US Group. Timing of brain magnetic resonance imaging and neurodevelopmental follow-up were variable. Neurodevelopmental follow occurred earlier and more frequently, although for a shorter duration, in the non-WEOG.

CONCLUSIONS

We found significant variations in practices for TH for HIE across regions internationally. Future guidelines should incorporate resource availability in a global perspective.

Parents' Experiences of Therapeutic Hypothermia for Neonates With Hypoxic-Ischemic Encephalopathy (HIE): A Single-Center Cross-Sectional Study

BACKGROUND AND OBJECTIVES

The purpose of the study is to assess parental experiences of therapeutic hypothermia for moderate to severe hypoxic-ischemic encephalopathy with the goal of improving local clinical practice guidelines and fostering family-integrated care in neonates with hypoxic-ischemic encephalopathy.

METHODS

This single-center retrospective cross-sectional study included neonates and their parents registered in the Swiss National Asphyxia and Cooling Register between 2011 and 2021. Based on a literature review, an anonymous survey of parents of neonates with hypoxic-ischemic encephalopathy was developed and conducted using an online survey tool. Descriptive statistics were used to analyze the survey results.

RESULTS

The overall response rate to this survey was 64% (46/72). Sufficient information about hypoxic-ischemic encephalopathy was reported by 78% (36/46) of parents and sufficient information about the process of therapeutic hypothermia by 87% (40/46) of parents. The majority of parents indicated the need for, and at least a satisfactory perception of, professional (91%; 42/46) and emotional (87%; 40/46) support. Parents identified fostering family involvement and regular family communication that focuses on family integrated care as areas for improvement.

CONCLUSIONS

There is still an unmet need for multidisciplinary teams to provide professional, empathetic, high quality, and family-integrated care to families with a neonate receiving therapeutic hypothermia for moderate or severe hypoxic-ischemic encephalopathy.

Transition in the Context of Parental Participation in Caring for Infants in Neonatal Intensive Care Units: An Evolutionary Concept Analysis

While participating in the care for a baby in a neonatal intensive care unit, parents experience a transition in which they adapt to changes and reconstruct their roles and identities. However, there is no clear explanation for this concept of transition. The purpose of this study was to clarify this concept using Rodgers' evolutionary approach. The identified attributes of the concept were a process of learning, repeated undulating emotions, balancing a caring relationship with nurses, and embracing new roles and responsibilities. The findings can provide a knowledge base for future research aimed at enhancing nurses' understanding of transition and promoting parental participation.

Variations in care of neonates during therapeutic hypothermia: call for care practice bundle implementation

BACKGROUND

Therapeutic hypothermia (TH) is the gold-standard treatment for moderate and severe neonatal encephalopathy (NE). Care during TH has implications for long-term outcomes. Outcome variability exists among neonatal intensive care units (NICUs) in Canada, but care variations are not understood well. This study examines variations in care practices for neonates with NE treated with TH in NICUs across Canada.

METHODS

A non-anonymous, web-based questionnaire was emailed to tertiary NICUs in Canada providing TH for NE to assess care practices during the first days of life and neurodevelopmental follow-up.

RESULTS

Ninety-two percent (24/26) responded. Centres followed national guidelines regarding the use of the modified Sarnat score to assess the initial severity of NE, the need to initiate TH within the first 6 h of birth, and the importance of follow-up. However, other practices varied, including ventilation mode, definition/treatment of hypotension, routine echocardiography, use of sedation, use of electroencephalogram (EEG), MRI timing, placental analysis, and follow-up duration.

CONCLUSIONS

NICUs across Canada follow available national guidelines, but variations exist in practices for managing NE during TH. Development and implementation of a consensus-based care bundle for neonates during TH may reduce practice variability and improve outcomes.

IMPACT

This survey describes the current HIE care practices and variation among tertiary centres in Canada. Variations exist in the care of neonates with NE treated with TH in NICUs across Canada. This paper Identifies areas of variation that are not discussed in detail in the national guidelines and will help to set up quality improvement initiatives. Elucidating the variation in care practices calls for the creation and implementation of a national, consensus-based care bundle, with the objective to improve the outcomes of these critically ill neonates.

The Role of Music Therapy with Infants with Perinatal Brain Injury

Perinatal brain injury occurs in 5.14/1000 live births in England. A significant proportion of these injuries result from hypoxic ischaemic encephalopathy (HIE) in term infants and intracranial haemorrhage (IVH) or periventricular leukomalacia (PVL) in preterm infants. Standardised care necessitates minimal handling from parents and professionals to reduce the progression of injury. This can potentially increase parental stress through the physical inability to bond with their baby. Recent research highlights the ability of music therapy (MT) to empower parental bonding without handling, through sharing culturally informed personal music with their infant. This review therefore aimed to systematically evaluate the use of MT with infants diagnosed with perinatal brain injury in a neonatal intensive care unit (NICU). Search terms were combined into three categories (audio stimulation (MT), population (neonates) and condition (brain injury), and eight electronic databases were used to identify relevant studies following PRISMA guidelines. Eleven studies using music or vocal stimulation with infants diagnosed with perinatal brain injury were identified and quality assessed using Cochrane ROB2, the ROBINSI Tool and the Newcastle Ottawa Scale. Studies used either voice as live (n = 6) or pre-recorded (n = 3) interventions or pre-recorded instrumental music (n = 2). Studies had two primary areas of focus: developmental outcomes and physiological effects. Results suggested the use of music interventions led to a reduction of infants' pain scores during procedures and cardiorespiratory events, improved feeding ability (increase oral feeding rate, volume intake and feeds per day) and resulted in larger amygdala volumes than control groups. Additionally, MT intervention on the unit supported long-term hospitalised infants in the acquisition of developmental milestones. Vocal soothing was perceived to be an accessible intervention for parents. However, infants with PVL showed signs of stress in complex interventions, which also potentially resulted in an increase in maternal anxiety in one study. MT with infants diagnosed with perinatal brain injury can have positive effects on infants' behavioural and neurological parameters and support parental involvement in their infants' developmental care. Further feasibility studies are required using MT to determine appropriate outcome measures for infants and the support required for parents to allow future comparison in large-scale randomised control trials.

Proposing a care practice bundle for neonatal encephalopathy during therapeutic hypothermia

Neonates with neonatal encephalopathy (NE) often present with multi-organ dysfunction that requires multidisciplinary specialized management. Care of the neonate with NE is thus complex with interaction between the brain and various organ systems. Illness severity during the first days of birth, and not only during the initial hypoxia-ischemia event, is a significant predictor of adverse outcomes in neonates with NE treated with therapeutic hypothermia (TH). We thus propose a care practice bundle dedicated to support the injured neonatal brain that is based on the current best evidence for each organ system. The impact of using such bundle on outcomes in NE remains to be demonstrated.

Management of comfort and sedation in neonates with neonatal encephalopathy treated with therapeutic hypothermia

Ensuring comfort for neonates undergoing therapeutic hypothermia (TH) after neonatal encephalopathy (NE) exemplifies a vital facet of neonatal neurocritical care. Physiologic markers of stress are frequently present in these neonates. Non-pharmacologic comfort measures form the foundation of care, benefitting both the neonate and parents. Pharmacological sedatives may also be indicated, yet have the potential to both mitigate and intensify the neurotoxicity of a hypoxic-ischemic insult. Morphine represents current standard of care with a history of utilization and extensive pharmacokinetic data to guide safe and effective dosing. Dexmedetomidine, as an alternative to morphine, has several appealing characteristics, including neuroprotective effects in animal models; robust pharmacokinetic studies in neonates with NE treated with TH are required to ensure a safe and effective standard dosing approach. Future studies in neonates treated with TH must address comfort, adverse events, and long-term outcomes in the context of specific sedation practices.

When all I wanted was to hold my baby-The experiences of parents of infants who received therapeutic hypothermia

AIM

The knowledge is limited about how parents experience the time when their infant is receiving therapeutic hypothermia (TH) after severe perinatal asphyxia. The aim of this study was to explore parents' experience of closeness and involvement in their infant's care while in the neonatal intensive care unit (NICU) with their newborn undergoing TH.

METHODS

Face-to-face, semi-structured interviews were conducted with parents (n = 11) whose infants (n = 8, aged 3-5 years at the time of the study) underwent TH at a level III Swedish NICU during 2013-2016. The interviews were analysed using qualitative content analysis.

RESULTS

All the parents shared the trauma of being both physically and psychologically separated from their infant. They all described a need for information and emotional support, and reported that the NICU staff had influenced the extent to which they as parents had been able to be near and actively participate in the care. Parents described the wish to be closer to their infant and to be more actively involved in their infant's care.

CONCLUSION

Strategies to enable parent-infant closeness and active guidance from staff might help alleviate the emotional stress of parents and promote their participation during TH.

Parental viewpoints and experiences of therapeutic hypothermia in a neonatal intensive care unit implemented with Family-Centred Care

AIMS AND OBJECTIVES

To explore parental experiences of therapeutic hypothermia (TH) in their newborn infant suffering from hypoxic ischaemic encephalopathy following perinatal asphyxia.

BACKGROUND

Since more than a decade, newborn infants are treated with TH following perinatal asphyxia to reduce mortality and disabilities and to improve neurological outcome. The infants' body temperature is lowered to 33.5°C for 72 hr, and the infant is usually cared for in an open incubator. The parents are not able to hold their infant skin to skin, which risks causing emotional reactions in parents and a loss of normal parent-infant bonding.

DESIGN

A qualitative descriptive design using semi-structured interviews.

METHODS

Up to 7 months after the event, interviews were conducted with 14 parents of seven infants who had received TH in a neonatal intensive care unit (NICU) in Sweden. The interviews were transcribed and analysed using framework approach. Findings were reported following the Standard for Reporting Qualitative Research (SRQR) checklist.

RESULTS

From the interviews, an overall theme was found: Transition through a life-altering time, and three categories: (a) trepidation about prognosis, (b) transitioning into parenthood supported by the caring philosophy of family-centred care (FCC) and (c) rewarming as a milestone.

CONCLUSIONS

Parental experiences of TH are based on the immediate emotions and stress of uncertainty of the infant's prognosis. The values of FCC in the NICU append a natural transitioning into parenthood by parental involvement in nursing care and decisions. The rewarming of the infant is seen as a restart to more or less normal circumstances from the critical period of delivery and TH.

RELEVANCE FOR CLINICAL PRACTICE

The management of NICUs should update the awareness of and deepen knowledge about FCC. The emphasis ought to be on adequate information about TH and the values of FCC to parents in the NICU context.
