Protocol for neonatal pain assessment and management: Application of the ALPS Neo scale in routine care

Abstract

Background and objectives. Neonatal pain research has advanced, disproving earlier beliefs that neonates cannot feel pain due to immature nervous systems. Incomplete myelination slows but does not prevent pain conduction. Pain responses start around 7.5 weeks post-conception, with pain receptors throughout the body by 20 weeks. Pain pathways are established by 22 weeks, but full modulation develops by 32 weeks, making preterm infants more sensitive. Nociceptors detect pain through A-delta (sharp pain) and C-fibers (dull pain). Tissue damage releases chemicals that lower the pain threshold. Pain is classified as nociceptive, somatic, or visceral and can be acute or chronic. Early pain exposure affects later responses. Validated pain scales for neonates include COVERS, PIPP, NIPS, NFCS, and ALPS Neo. Current practice emphasizes preventing and treating pain to minimize stress. Materials and methods. This study at Life Memorial Hospital will analyze patients over 1 month and over 6 months, with ethical approval obtained beforehand. Inclusion criteria: neonates with a gestational age over 35 weeks, birth weight over 2000 grams, needing routine care. Exclusion criteria: neonates needing respiratory support/sedation or with abnormal neurological exams. We will use the ALPS Neo pain assessment scale for its reliability and ease of integration into daily care, aiming to reduce pain or stress duration. Patients will be scored on facial expression, breathing, extremity tone, hand/foot activity, and activity level. Scores of 3-5 will prompt non-pharmacological interventions. Scores above 5 will require frequent reassessments and possible pharmacological intervention. The medical team will be trained on the ALPS Neo scale and non-pharmacological pain reduction methods. Pain from procedures like vaccinations will be assessed during the first two days of life. Initially, control patients will be evaluated without interventions. Over the next 6 months, patients will receive non-pharmacological interventions, including non-nutritive sucking, sucrose, Kangaroo Mother Care, swaddling, and maternal milk or formula. Our group aims to establish an evidence-based protocol for pain assessment and management and to use it in prospective research in which the objectives would be to use a pain scale for more accurate pain data from procedures, identify and reduce the most painful procedures, evaluate and improve the effectiveness of pain management strategies. Conclusions. This observational study at Life Memorial Hospital will use the ALPS Neo pain assessment scale to improve neonatal pain management within the Kangaroo Mother Care program. By comparing a 1-month control group with a 6-month group, we aim to identify and reduce procedural pain. The ALPS Neo scale will enable precise pain assessment and targeted non-pharmacological interventions, potentially guiding future pain management strategies. The choice of ALPS Neo, which is familiar to our team, will ease training and implementation. Success may lead to exploring scales with objective measures, though ALPS Neo will initially drive our improvements in pain management.
