Background and study aims
Each year around 2100 live born babies develop brain damage due to lack of oxygen at birth. These babies have cooling therapy and intensive care for almost four days to reduce long-term disabilities. However, nearly half of cooled babies die or develop disabilities. Given this risk, parents are under extreme stress, which is made worse by the current practice of not allowing parents to cuddle their babies during cooling therapy, due to concerns of affecting the cooling process and intensive care. This practice may affect the bonding between mothers and cooled babies, which in turn could affect establishing breastfeeding. Impaired parent-infant bonding could affect their mental health and brain development of the child.
Aim: Refine a ‘CoolCuddle’ intervention pathway to enable parents to cuddle their babies during cooling.
Who can participate?
Newborn infants born at gestation ≥ 36 weeks undergoing whole-body cooling for hypoxic-ischemic encephalopathy
What does the study involve?
The study will include St Michael’s and Southmead Hospital’s neonatal units in Bristol. The ‘CoolCuddle’ process with babies having cooling therapy will be led by two nurses and have 2 stages.
1. For 4 parent-infant pairs, the researchers will follow a standard procedure of safely moving the baby from the open cot to parent’s arms after fixing the tubes and lines attached to the baby. The researchers will have at least one cuddle episode for each infant for up to 2 hours at a time. The researchers will record whether the parents are keen to do this and collect data on breathing support, heart rate, blood pressure, oxygen levels, brain activity and temperature.
2. Based on these results, the researchers will refine ’CoolCuddle’ and then test it with further 20-24 parent-infant pairs. The researchers will measure its effect on the stability of the cooling process, breathing support, heart function, brain activity.
The researchers will collect data on duration of breastfeeding, length of hospital stay, parental mood and parent-infant bonding scores to decide outcomes for future study. The researchers will develop a modified cooling therapy pathway including the “CoolCuddle”.
The researchers will invite all parents and staff to be interviewed to explore their views of ‘CoolCuddle’ at both stages to improve the process and find out what they feel about it.
What are the possible benefits and risks of participating?
Benefits: Information from this part of the study will help us to evaluate the new process of cuddling babies during cooling therapy and its safety. The study will also be useful in developing ways to promote bonding between future mothers and their babies who need cooling therapy.
Risks: The researchers do not know how the baby might tolerate the cuddle during cooling therapy. However, the baby’s medical and nursing staff will closely monitor the baby and the researchers will talk to parents all the time during the process. Completing the questionnaires and taking part in the interview will take some of the parents' time and attention.

| Scientific title | Evaluation of feasibility and physiological stability of parents cuddling babies during cooling therapy for hypoxic ischaemic encephalopathy: a quantitative and qualitative study |
| Study acronym | Coolcuddle study |
| Study objectives | Aims: 1. To develop the existing cuddling technique for non-cooled babies receiving intensive care into a “CoolCuddle” protocol using the physiology stability data during cuddling and qualitative data from nurses, parents and medical staff 2. To investigate whether the “CoolCuddle” protocol would maintain stable cooling therapy, respiratory, cardiovascular and neurophysiology 3. To investigate the barriers and facilitators of cuddling during cooling from parents and nurses using a qualitative approach 4. To develop a modified cooling therapy pathway with the “CoolCuddle” protocol incorporated into the pathway |

| Health condition(s) or problem(s) studied | Neonatal hypoxic ischaemic encephalopathy |
| Intervention | Parents of babies undergoing therapeutic hypothermia for neonatal hypoxic-ischaemic encephalopathy as per the regional protocol will be recruited after informed consent during the cooling period to cuddle their babies during cooling therapy/rewarming and intensive care. In stage 1, we will refine the current cuddling process used for non-cooled babies receiving intensive care by using it on four parent-infant dyads. Using the physiological monitoring data and input from nurses and parents, we will develop a standard operating procedure of cuddling process that will be investigated in stage 2. In stage 2, 20-24 parents of babies undergoing cooling therapy and intensive care will be recruited. Each family will be offered at least one cuddle during cooling/rewarming and intensive care. Physiological monitoring will include cardiorespiratory and neurophysiological, including amplitude-integrated electroencephalography and near-infrared spectroscopy. Participating mothers will complete the Edinburgh Postnatal Depression scale and Mother-to- infant bonding scale when the baby is 5-7 days and at 8 weeks of age. Participating fathers will complete paternal postnatal attachment scale when the baby is 8 weeks old. Parents (up to 20) and staff (n=6) will undergo qualitative interviews. |
