Eligible studies included primary research, high-quality secondary evidence, and clinically relevant methodological or technological studies involving preterm or term neonates, defined as infants with a birth age of \u226428 days, or infants cared for in neonatal intensive care units. Studies were included if they addressed the development, validation, or clinical application of neonatal pain assessment tools, or the efficacy, safety, or implementation of non-pharmacological analgesic interventions. Studies limited to pharmacological analgesia, older children, or adults were excluded.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Thirty-five studies were included. The evidence supports the use of validated multidimensional assessment tools for structured evaluation of neonatal pain. It indicates that family-integrated, sensory, and behavioral non-pharmacological approaches can reduce procedural pain responses. However, the strength and consistency of evidence are greater for single procedures than for repeated or prolonged pain. Artificial intelligence-based facial expression analysis, physiological monitoring, and biomarker-based approaches show potential for more objective pain detection but remain insufficiently validated for routine bedside decision-making.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Standardized neonatal pain management should combine validated assessment scales, protocolized first-line non-pharmacological care, staff training, and parent involvement.
