Paediatric & Neonatal Pain
|May 13, 2022
Summary
Infants perceive pain, and early exposure can alter brain development. Research shows repetitive pain in preterm infants affects stress systems and neurodevelopment long-term.
Area of Science:
- Neonatal research
- Neuroscience
- Developmental psychology
Background:
- Historical view of infant pain perception.
- Established understanding of pain perception in newborns.
- Identification of critical pain exposure windows in infancy.
Purpose of the Study:
- Investigate long-term effects of early pain exposure in preterm infants.
- Explore altered brain development and stress system programming.
- Propose biological pathways linking pain to neurodevelopmental outcomes.
Main Methods:
- Multidisciplinary research approach.
- Analysis of data from infants born very preterm.
- Review of discovery research and biological evidence.
Main Results:
- Repetitive pain exposure in late fetal life (ex-utero) is linked to adverse outcomes.
- Altered brain development observed in affected infants.
- Programming of stress systems contributes to neurodevelopmental changes.
Conclusions:
- Early life pain significantly impacts infant neurodevelopment.
- Understanding these pathways is crucial for intervention.
- Further research into biological mechanisms is warranted.

01:25Analgesia and Pain Management
835
Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...

Pain serves as a critical warning signal that alerts the body to potential or actual harm. When mechanical pressure on the skin is intense, such as from a sharp pinch, the sensation transitions from touch to pain. Similarly, extreme temperatures, like a hot pot handle, convert the sensation of heat into pain. Pain can also result from overstimulation of other senses, such as blinding light, loud noise, or the intense heat from habañero peppers. This ability to sense pain is essential for...

01:44Nociception
29.6K
Nociception—the ability to feel pain—is essential for an organism’s survival and overall well-being. Noxious stimuli such as piercing pain from a sharp object, heat from an open flame, or contact with corrosive chemicals are first detected by sensory receptors, called nociceptors, located on nerve endings. Nociceptors express ion channels that convert noxious stimuli into electrical signals. When these signals reach the brain via sensory neurons, they are perceived as pain.

01:21The Nativist Approach
156
The nativist approach to infant cognitive development proposes that infants are born with inherent knowledge structures that allow them to interpret the world almost immediately. This perspective contrasts with earlier developmental theories, such as those proposed by Jean Piaget, which emphasized a more gradual acquisition of cognitive abilities through interaction with the environment. One key concept in this approach is object permanence — the understanding that objects continue to...

The history of therapeutic communication can be traced back to Florence Nightingale, who emphasized the importance of developing trusting relationships with patients. She taught that the presence of nurses with patients results in therapeutic healing.
Therapeutic communication is not the same as social interaction. Social interaction has no goal or purpose and consists of casual information sharing, whereas therapeutic communication has a plan or purpose for the conversation. Therapeutic...
