Abstract: Parental involvement in neonatal comfort care is a core component of family-centred care. Yet, parents experience a range of positive and negative feelings when providing pain-relieving interventions for their infants. Parents of infants who participated in the Parental touch trial ( Petal ), a multicentre randomised controlled trial investigating the impact of gentle parental touch on neonatal pain, were asked to complete an anonymous survey. This survey aimed to (1) explore parent-reported motivations in deciding to participate in the Petal trial; (2) understand parent-reported experiences related to trial participation; (3) understand parents' willingness to participate in future studies; and (4) evaluate parent-reported feelings while they were delivering a gentle touch intervention either before or after a clinically necessary blood test. One hundred six parents (1 parent per infant) took part in the survey. Primary motivators for participation were altruistic. Parents most frequently reported that they wanted their child to take part in the research because it has a potential benefit to babies in the future and because they wanted to improve scientific understanding. Parents reported that providing gentle touch to their children during painful procedures was associated with positive emotions, such as feeling "useful" (64%) and "reassured" (53%). Furthermore, nearly all parents (98%) were pleased to have participated in the Petal trial and would consider, or maybe consider, participating in further research studies. These results underscore the importance of structuring trials around parental involvement and providing opportunities for parents to be involved in providing comfort to their infants during necessary painful clinical procedures., (Copyright © 2024 The Author(s).

More than 235,000 children/year in the UK receive general anaesthesia, but it is unknown whether nociceptive stimuli alter cortical brain activity in anaesthetised children. Time-locked electroencephalogram (EEG) responses to experimental tactile stimuli, experimental noxious stimuli, and clinically required cannulation were examined in 51 children (ages 1-12 years) under sevoflurane monoanaesthesia. Based on a pilot study (n=12), we hypothesised that noxious stimulation in children receiving sevoflurane monoanaesthesia would evoke an increase in delta activity. This was tested in an independent sample of children (n=39), where a subset (n=11) had topical local anaesthetic applied prior to stimulation. A novel method of time-locking the stimuli to the EEG recording was developed using an event detection interface and high-speed camera. Clinical cannulation evoked a significant increase (34.2 ± 8.3%) in delta activity (P=0.042), without concomitant changes in heart rate or reflex withdrawal, which was not observed when local anaesthetic was applied (P=0.30). Experimental tactile (P=0.012) and noxious (P=0.0099) stimulation also evoked significant increases in delta activity, but the magnitude of the response was graded with stimulus intensity, with the greatest increase evoked by cannulation. We demonstrate that experimental and clinically essential noxious procedures, undertaken in anaesthetised children, alter the pattern of EEG activity, that this response can be inhibited by local anaesthetic, and that this measure is more sensitive than other physiological indicators of nociception. This technique provides the possibility that sensitivity to noxious stimuli during anaesthesia could be investigated in other clinical populations., (Copyright © 2014 The Authors.
