Insights

Assessing infant pain is difficult. Near-infrared spectroscopy measures cortical responses to pain, offering a way to validate current clinical pain assessment tools for neonates.

Area of Science:

  • Neuroscience
  • Neonatal care
  • Pain research

Background:

  • Pain measurement in neonates is challenging due to their inability to verbally express pain.
  • Current pain assessment relies on behavioral and physiological indicators, which may not accurately reflect cortical pain processing.
  • Higher cortical processing is essential for the perception of pain.

Purpose of the Study:

  • To review the application of near-infrared spectroscopy (NIRS) in assessing neonatal pain.
  • To compare NIRS-based cortical responses with existing clinical pain assessment measures.
  • To determine if current measures truly reflect cortical pain processing in infants.

Main Methods:

  • Review of recent studies utilizing near-infrared spectroscopy (NIRS) in neonates.
  • Comparison of NIRS-measured cortical responses to nociception with established clinical pain assessment tools.
  • Analysis of the correlation between outcome measures and perceived pain requiring higher cortical processing.

Main Results:

  • Near-infrared spectroscopy (NIRS) enables direct measurement of cortical responses to nociception in neonates.
  • NIRS provides an objective measure to evaluate the validity of current behavioral and physiological pain indicators.
  • The magnitude of cortical responses measured by NIRS can be compared against clinical pain scores.

Conclusions:

  • Near-infrared spectroscopy (NIRS) offers a promising method for objective pain assessment in neonates.
  • Further research is needed to validate NIRS as a reliable measure of perceived pain in infants.
  • Comparing NIRS data with clinical measures can enhance the accuracy of pain management in vulnerable neonates.

Somatosensation01:33

Somatosensation

The somatosensory system relays sensory information from the skin, mucous membranes, limbs, and joints. Somatosensation is more familiarly known as the sense of touch. A typical somatosensory pathway includes three types of long neurons: primary, secondary, and tertiary. Primary neurons have cell bodies located near the spinal cord in groups of neurons called dorsal root ganglia. The sensory neurons of ganglia innervate designated areas of skin called dermatomes.
Thermosensation01:43

Thermosensation

Peripheral thermosensation is the perception of external temperature. A change in temperature (on the surface of the skin and other tissues) is detected by a family of temperature-sensitive ion channels called Transient Receptor Potential, or TRP, receptors. These receptors are located on free nerve endings. Those detecting cold temperatures are closer to the surface of the skin than the nerve endings detecting warmth. These thermoTRP channels, while temperature selective, have relatively...
Nociception01:44

Nociception

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. Thus, pain helps the...
Sensory Functions of the Skin01:16

Sensory Functions of the Skin

The skin is the largest organ of the human body and plays a crucial role in our sensory perception. It contains a vast network of sensory receptors that contribute to the skin's protective function by perceiving physical, biological, and environmental cues and generating relevant responses.
There are two main categories of receptors on the skin: capsulated and non-capsulated. The non-capsulated ones are mainly the pain receptors. The capsulated ones can be further categorized based on the...
Local Anesthetics: Differential Sensitivity of Nerve Fibers01:24

Local Anesthetics: Differential Sensitivity of Nerve Fibers

Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...
Pain01:20

Pain

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...
