Survey of Neonatal Intensive Care Unit Nurse Attitudes Toward Therapeutic Hypothermia Treatment

A Pilot Randomized Control Trial of Holding During Hypothermia and Effects on Maternal and Infant Salivary Cortisol Levels

BACKGROUND

The lack of physical contact during therapeutic hypothermia (TH) is challenging for parents of newborns with hypoxic ischemic encephalopathy. Holding is often avoided due to concerns for effects on infant temperature and for dislodging equipment.

PURPOSE

We assessed the effect of holding during TH on maternal and infant salivary cortisol levels and on infant vital signs.

METHODS

Prospective crossover study with infants randomized to a 30-minute session of holding on day-2 versus day-3 of TH. "No-holding" occurred on the alternate day at the same time. Pre- and post-holding salivary cortisol levels were compared between holding and no-holding conditions. Vital signs were collected at 2-minute intervals. Data was analyzed using mixed-effects models.

RESULT

Thirty-four mothers and infants were recruited. The median gestational age was 39 weeks, 16 (94%) had moderate encephalopathy and all were on morphine during TH. Salivary cortisol levels decreased after holding for infants on day-2 ( P = .02) and mothers on day-2 and day-3 ( P = .01). Infants held on day-2, but not on day-3, had lower heart rates, respiratory rates, and mean arterial pressures. Temperature and oxygen saturations were stable on both days.

IMPLICATIONS FOR PRACTICE AND RESEARCH

We demonstrate positive effects of holding during TH as evidenced by lower salivary cortisol for both mother and infant and decreased heart rate, respiratory rate, and blood pressure for the infant on day-2. Further research is needed to replicate these results, to understand the lack of infant response on day-3 and to assess correlation with cumulative morphine exposure.

Clinician Stakeholder Experience With Telemedicine Consults to Assess Neonatal Encephalopathy in a Rural State

BACKGROUND

Serial neonatal encephalopathy (NE) examinations are difficult to perform in rural community hospitals as on-site experts are not readily available. We implemented a synchronous, acute care model of teleconsultation-the Maine Neonatal Encephalopathy Teleconsultation program (Maine NET)-to provide remote, joint assessment of NE by pediatric neurology and neonatology at nine community hospitals and one tertiary care center. We performed a qualitative study to interview clinicians about their experience of this program.

METHODS

From April 2018 to October 2022, we employed a semistructured interview format with 16 clinicians representing all participating hospitals. We utilized deductive analysis to assign a set of predefined codes to the transcribed interviews.

RESULTS

Thematic analysis supported the anticipated benefits of Maine NET, demonstrating that clinicians felt resource utilization, collaborative decision making, communication, and continuity of care were improved. Clinicians overwhelmingly supported the program: "This program has truly saved babies' lives and future function. I have not met any parents through this journey, who aren't incredibly grateful for the care that is provided" and emphasized the benefit of collaboration between all care team members. Teleconsultation was felt to be "more than adequate to [assess] NE." Connectivity issues were cited as a limitation.

CONCLUSIONS

Maine NET has positively impacted care delivery for newborns with clinical concerns for NE. Additionally, the program has improved resource allocation, collaborative decision making, communication, and equity of care. Addressing technological challenges will be vital to the success and sustainability of the planned Maine NET expansion.

Communicating with Parents About Therapeutic Hypothermia and Hypoxic Ischemic Encephalopathy: Integrating a Palliative Care Approach into Practice

Parents of newborns with hypoxic ischemic encephalopathy (HIE) can face communication challenges in the neonatal intensive care unit. Both specialty palliative care and primary palliative care trained clinicians can assist parents as they navigate traumatic experiences and uncertain prognoses. Using evidence-based frameworks, the authors provide samples of how to communicate with parents and promote parent well-being across the care trajectory. The authors demonstrate how to involve parents in a shared decision-making process and give special consideration to the complexities of hospital discharge and the transition home. Sustained investment to guide the development of effective communication skills is crucial to support families of infants with HIE.

Analgesia and sedation strategies in neonates undergoing whole-body therapeutic hypothermia: A scoping review

BACKGROUND

Therapeutic hypothermia (TH) is a widely practiced neuroprotective strategy for neonates with hypoxic-ischemic encephalopathy. Induced hypothermia is associated with shivering, cold pain, agitation, and distress.

OBJECTIVE

This scoping review determines the breadth of research undertaken for pain and stress management in neonates undergoing hypothermia therapy, the pharmacokinetics of analgesic and sedative medications during hypothermia and the effect of such medication on short- and long-term neurological outcomes.

METHODS

We searched the following online databases namely, (i) MEDLINE, (ii) Web of Science, (iii) Cochrane Library, (iv) Scopus, (v) CINAHL, and (vi) EMBASE to identify published original articles between January 2005 and December 2022. We included only English full-text articles on neonates treated with TH and reported the sedation/analgesia strategy used. We excluded articles that reported TH on transport or extracorporeal membrane oxygenation, did not report the intervention strategies for sedation/analgesia, and reported hypoxic-ischemic encephalopathy in which hypothermia was not applied.

RESULTS

The eligible publications (n = 97) included cohort studies (n = 72), non-randomized experimental studies (n = 2), pharmacokinetic studies (n = 4), dose escalation feasibility trial (n = 1), cross-sectional surveys (n = 5), and randomized control trials (n = 13). Neonatal Pain, Agitation, and Sedation Scale (NPASS) is the most frequently used pain assessment tool in this cohort. The most frequently used pharmacological agents are opioids (Morphine, Fentanyl), benzodiazepine (Midazolam) and Alpha2 agonists (Dexmedetomidine). The proportion of neonates receiving routine sedation-analgesia during TH is center-specific and varies from 40-100% worldwide. TH alters most drugs' metabolic rate and clearance, except for Midazolam. Dexmedetomidine has additional benefits of thermal tolerance, neuroprotection, faster recovery, and less likelihood of seizures. There is a wide inter-individual variability in serum drug levels due to the impact of temperature, end-organ dysfunction, postnatal age, and body weight on drug metabolism.

CONCLUSIONS

No multidimensional pain scale has been tested for reliability and construct validity in hypothermic encephalopathic neonates. There is an increasing trend towards using routine sedation/analgesia during TH worldwide. Wide variability in the type of medication used, administration (bolus versus infusion), and dose ranges used emphasizes the urgent need for standardized practice recommendations and guidelines. There is insufficient data on the long-term neurological outcomes of exposure to these medications, adjusted for underlying brain injury and severity of encephalopathy. Future studies will need to develop framework tools to enable precise control of sedation/analgesia drug exposure customized to individual patient needs.

The competence of neonatal intensive care nurses: A systematic review

OBJECTIVE

The objective was to conduct a systematic review describing the competencies required from nurses working in neonatal intensive care settings.

DESIGN

Systematic review.

DATA SOURCES

A total of eight databases, including PubMed, Scopus, CINAHL, MEDLINE, Mednar, Web of Science, ProQuest and Medic, were screened for relevant literature during February and September 2022.

REVIEW METHODS

The systematic review process followed Joanna Briggs Institute guidelines. The inclusion criteria were: 1) (P = population) registered nurses; 2) (C = concept) the competence; 3) (C = context) nursing in neonatal intensive care units; and 4) cross-sectional study as study method. A critical appraisal tool for cross-sectional studies from Joanna Briggs Institute was used by two independent reviewers. After data extraction, thematic analysis was performed.

RESULTS

The database searches yielded a total of 8887 studies and after two independent evaluations, a total of 50 eligible studies were identified comprising of 7536 registered nurses working in neonatal intensive care units across 19 countries. The studies described four main competence themes: 1) neonatal care interventions; 2) caring for a dying infant; 3) family-centered care; and 4) neonatal intensive care interventions.

CONCLUSION

Previous research has focused on evaluating specific competencies that are necessary in the neonatal intensive care setting. There is a need for research concerning the overall competence of nurses working in neonatal intensive care units. There was a lot of variety within the quality of the eligible studies and within the used instruments.

'Opportunity to bond and a sense of normality': Parent and staff views of cuddling babies undergoing therapeutic hypothermia in neonatal intensive care: 'CoolCuddle'

Background

Currently, parents whose sick babies are undergoing three days of cooling therapy for hypoxic–ischaemic encephalopathy in neonatal intensive care units (NICUs) are not permitted to cuddle their cooled babies, due to concerns of warming the baby or dislodging breathing tubes or vascular catheters. Parents want to stay and care for their cooled babies and have reported that bonding is adversely affected when they are not permitted to hold them.

Design and Participants

Qualitative interviews with 21 parents of cooled babies in NICU (11 mothers and 10 fathers) and 10 neonatal staff (4 consultants and 6 nurses) explored their views and experiences of an intervention to enable parents to cuddle their cooled babies (CoolCuddle). Thematic analysis methods were used to develop the themes and compare them between parents and staff.

Results

Five themes were produced. Three themes were comparable between parents and staff: Closeness, a sense of normality and reassurance and support. An additional parent theme reflected their mixed feelings about initial participation as they were apprehensive, but felt that it was an amazing opportunity. Parents and staff described the closeness between parents and babies as important for bonding and breastfeeding. Fathers particularly appreciated the opportunity to hold and bond with their infants. Parents valued the reassurance and support received from staff, and the cuddles helped them feel more normal and more like a family at a very stressful time. In a final staff theme, they discussed the skills, number of staff and training needed to undertake CoolCuddle in NICU.

Conclusions

Parents cuddling their babies during cooling therapy enhanced parent–infant bonding and family‐centred care in NICU and was positively received. Adverse perinatal mental health, impaired mother–infant bonding and their effects on the establishment of breastfeeding may be ameliorated by introducing CoolCuddle.

Patient Contribution

Our parent advisors contributed to the interview topic guides and endorsed the themes from the analysis.

Supporting families in their child's journey with neonatal encephalopathy and therapeutic hypothermia

Neonates and families face challenges in hypothermic therapy, including trauma to parents, extreme emotions, and unfamiliarity with the medical system. Communication is an essential element to supporting parents while their children are in the NICU, and beyond, building the foundation for the ongoing relationship the family has with the medical system. Significant consideration needs to be given to the critical element of integrating the family into the care of a baby being treated with therapeutic hypothermia. Clinicians can promote healing of accumulated traumas of parents through ensuring parent's emotional safety, facilitating a trusting relationship, and promoting parent empowerment. Connecting parents with resources, especially peer support, is an essential part of a hospital stay. In this chapter, we explore best practices to support families during and after hypothermic therapy.

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.

Maternal holding during therapeutic hypothermia for infants with neonatal encephalopathy is feasible

AIM

Concerns for infant destabilisation often prohibit parental holding of infants during therapeutic hypothermia (TH). We assessed the feasibility of maternal holding during TH, as the inability to hold can impede bonding.

METHODS

Vital signs were assessed in stable infants before, at two-minute intervals during and 30 minutes after a single 30-minute holding session. The infant remained on the blanket throughout holding, and both infant and blanket were placed into the mother's arms on top of a thin foam insulating barrier. Mothers and nurses were surveyed about their experience.

RESULTS

Ten infants undergoing TH for neonatal encephalopathy had no equipment malfunctions or dislodgement. The mean temperature was 33.4°C prior to and 33.5°C (p = 0.18) after holding. There was no significant bradycardia (heart rate <80 beats per minute), hypotension (mean arterial pressure <40 mm Hg) or oxygen desaturation (<93%). Nurses either strongly agreed (75%) or agreed (25%) with the statement 'After assisting with the holding protocol, I feel that holding during cooling is safe'. Mothers (100%) strongly agreed that other parents would benefit from holding.

CONCLUSION

In a small sample of ten stable infants treated with TH for neonatal encephalopathy, holding resulted in no adverse events and positive feedback from mothers and nurses.

Parental perceptions of neonatal therapeutic hypothermia; emotional and healing experiences

Introduction: Parents of infants who undergo therapeutic hypothermia experience emotional challenges that have not been fully characterized. Comprehensive understanding of the parental experience of hypothermia is needed to provide better care to the family of the infant. This study aimed to improve the understanding of the parental emotional experience of therapeutic hypothermia in the Neonatal Intensive Care Unit (NICU).Methods: Semistructured interviews were conducted in a group setting with parents matched into groups according to the severity of the infant's presenting encephalopathy. The interviews were transcribed and coded into principal and additional subthemes.Results: Families of 15 infants, who were between 2 months and 2 years at the time of the interview, participated. Infants had a mean gestational age of 40.0 weeks and 11 (73%) were male. Eleven (73%) were transferred from other hospitals following birth and eight (53%) had seizures. Emotional Experiences was a principal theme and included subthemes of traumatic experiences, Loss of normalcy, and Separation of parent and infant. The birth was frequently described as traumatic with descriptions of chest compressions, excessive blood loss and infants not crying. Trauma was also described in the parental observations of the shivering hypothermic infant. Parents highlighted the loss of normalcy in terms of their expected birth narrative and the loss of the early opportunity to breastfeed and hold their infant. Parents reported that the physical separation imposed by hypothermia adversely impacted their ability to bond with their infant. Healing Experiences was the other principal theme with subthemes identified as Incorporation of parents into NICU care, Reclaiming parenthood and Support from other hypothermia families. Parents reported feeling a connection to their infant when they were involved in medical rounds and when asked to participate in routine care of their infant. Occasionally, parents strongly advocated for their own participation in a particular aspect of their infant's care such as a diaper change and this was perceived as reinforcing their role as parent. Lastly, parents requested greater access to peer support from parents who had experienced therapeutic hypothermia.Conclusion: Parents of infants treated with hypothermia reported the experience of their unexpected adverse delivery and their baby subsequently being treated with therapeutic hypothermia as traumatic. This trauma can be compounded by the pale, still and shivering appearance of their newborn and the delay in bonding as a result of physical separation during hypothermia treatment. Parents described feeling connected to their infant in the context of performing routine care activities and desired greater access to peer support. The themes reported in this study could be used to inform high level NICU care and raise provider awareness of the parent experience.

Exploring parent expectations of neonatal therapeutic hypothermia

OBJECTIVE

We aimed to assess the parent experience of therapeutic hypothermia (TH), specifically focusing on unmet expectations.

STUDY DESIGN

Open-ended questions were used in a focus group setting. We employed an inductive approach to develop thematic content from the transcribed recordings.

RESULTS

30 parents of infants treated with TH participated. Within the principal theme of managing expectations, four sub-themes emerged. These included parental concerns about morphine use; specifically the association of morphine with end-of-life care and addiction. Parents perceived their role as key in the decision to implement TH and were emotionally burdened by this during and after TH. Parents recall intense fear for the infant's immediate survival and were not sufficiently reassured regarding survival. Parents also experience ongoing uncertainties about the long-term prognosis after TH.

CONCLUSION

The identification of these four areas in which parents have unmet expectations is important in order to improve the delivery of care.

Exploring Parent Experience of Communication About Therapeutic Hypothermia in the Neonatal Intensive Care Unit

BACKGROUND

The unique communication challenges faced by parents of infants undergoing therapeutic hypothermia have not been well characterized.

PURPOSE

To develop awareness of communication challenges experienced by families of infants treated with therapeutic hypothermia.

METHODS

Semistructured interviews were conducted in a group setting with parents matched into groups according to the severity of the infant's presenting encephalopathy. The interviews were transcribed and coded into principal and additional subthemes.

RESULTS

Thirty adults were interviewed including 15 mothers, 12 fathers, 2 grandmothers, and 1 grandfather. The 15 infants were between 2 and 24 months of age at the time of the interviews. The principal theme of communication included the following 3 subthemes; transparency, consistency, and delivery style. Parents reported a strong desire for improved early and transparent communication about therapeutic hypothermia, particularly during transfer from an outside hospital. Parents also reported a preference for consistent communication and highlighted parental touch of the hypothermic infant, obstetrical nurse-to-neonatal intensive care unit nurse communication, and parent and visitor presence in the infant's room as areas in need of greater communication consistency. Parents valued direct and compassionate communication styles that excluded medical jargon.

IMPLICATIONS FOR PRACTICE

All providers can implement recommendations for communication to parents of infants treated with therapeutic hypothermia by increasing transparency, developing greater consistency in the communication delivered, and employing a direct and compassionate style to improve the parental experience of therapeutic hypothermia.

IMPLICATIONS FOR RESEARCH

Further investigation is needed into the specific challenges parents face with a lack of transparent communication prior to the transfer of an infant for therapeutic hypothermia.
