Sensory stimulation for apnoea mitigation in preterm infants.

Area of Science:

• Neonatal Medicine
• Developmental Neuroscience
• Respiratory Physiology

Background:

• Apnoea is common in preterm infants, leading to instability and potential neurodevelopmental issues.
• Current interventions for infant apnoea often require manual, reactive stimulation, which is insufficient.
• Existing therapies struggle to fully mitigate the burden of apnoeic events in hospitalized preterm infants.

Purpose of the Study:

• To review the effectiveness of various sensory stimulations in mitigating apnoea in preterm infants.
• To explore the potential of automated, closed-loop sensory stimulation systems for apnoea management.
• To identify the need for preventative and multi-modal stimulation approaches.

Main Methods:

• Systematic review of 31 studies on sensory stimulation for infant apnoea.
• Analysis of localized tactile, generalized kinesthetic, airway pressure, auditory, and olfactory stimulations.
• Evaluation of current automated stimulus: non-invasive intermittent positive pressure ventilation.

Main Results:

• All reviewed sensory stimulation methods demonstrated some positive effects on reducing apnoea frequency.
• Findings were not definitive, highlighting a lack of comparative studies.
• Non-invasive intermittent positive pressure ventilation is the sole automated clinical stimulus for persistent apnoea.

Conclusions:

• Automated closed-loop sensory stimulation systems are warranted for apnoea mitigation in preterm infants.
• Preventative and multi-modal sensory stimulation strategies should be developed.
• Further research is needed to establish definitive evidence and optimize stimulation protocols.
