ABSTRACT
OBJECTIVE:
To assess the effect of a non-noxious vibratory stimulus on noxious-evoked cortical responses to skin puncture and to determine whether the presence of certain behavioural components may be used to predict such cortical responses.DESIGN:
Randomised controlled trial.SETTING:
Level IV neonatal intensive care unit at a stand-alone children's hospital. PATIENTS 134 hospitalised infants between 36 and 52 weeks' postmenstrual age and ordered to receive a clinically required laboratory draw.INTERVENTIONS:
Infants randomised to receive the intervention, a vibratory stimulus at the site of skin puncture beginning 10 s prior to a heel stick, or the control, no vibration. MAIN OUTCOMEMEASURES:
Electroencephalography and video recording time-locked to the deployment of the lancet for the skin puncture. Noxious-evoked cortical responses were measured by the area under the curve in the somatosensory region contralateral to the skin puncture. Behavioural responses were coded through video analysis.RESULTS:
Noxious-evoked cortical responses were significantly reduced in participants receiving the vibratory stimulus compared with the control (frontal, p<0.0001; central, p=0.0088; central-parietal, p=0.0111). There were no significant differences in behavioural responses between groups (all p>0.05).CONCLUSIONS:
A non-noxious vibratory stimulus presented prior to and continuing simultaneously with skin puncture significantly mitigates nociception in hospitalised infants. The presence or absence of facial expression components is inadequate to reliably predict pain signalling in the brain. TRIAL REGISTRATION NUMBER NCT04050384.
