Insights

Early infant pain and stress can cause lasting physiological changes. These early experiences impact the central nervous system and stress responses later in life.

Area of Science:

  • Neonatal physiology
  • Developmental psychology
  • Pediatric medicine

Background:

  • Infant pain assessment and management present unique challenges.
  • Early life experiences significantly shape long-term health trajectories.
  • The consequences of neonatal pain and stress extend beyond immediate effects.

Purpose of the Study:

  • To review evidence on the long-term physiological consequences of early pain and stress in infants.
  • To highlight the lasting impact of neonatal painful insults on neurodevelopment and stress systems.

Main Methods:

  • Review of existing physiological studies on infant pain and stress.
  • Analysis of research on the central nervous system, neuroendocrine, and immune system responses.
  • Synthesis of evidence regarding long-term outcomes of early life adversity.

Main Results:

  • Painful experiences in early infancy can lead to significant and enduring physiological changes.
  • Neonatal pain insults are associated with alterations in the central nervous system.
  • Long-lasting changes in neuroendocrine and immune system responsiveness to stress are observed.

Conclusions:

  • Early life pain and stress have profound and lasting physiological consequences for infants.
  • These early experiences can alter the developing nervous, endocrine, and immune systems, affecting adult stress responses.
  • Understanding these long-term effects is crucial for optimizing infant care and long-term health outcomes.

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...
Local Anesthetics: Adverse Effects01:12

Local Anesthetics: Adverse Effects

While local anesthetics are generally safe and well-tolerated, they can occasionally cause adverse effects that vary in severity. Local anesthetics can induce toxicity at two distinct levels. They can either produce local effects through direct contact with the neural elements or be absorbed into the bloodstream from the injection site, leading to systemic effects.
Once absorbed into the systemic circulation, local anesthetics can affect the organs that depend on the functioning of sodium...
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...

Local Anesthetics: Clinical Application as Epidural Anesthesia

Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery.
Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...
Blood and Nerve Supply to the Bones01:29

Blood and Nerve Supply to the Bones

Bones are dynamic organs that require a rich supply of oxygen and nutrients. Around 5% to 10% of the cardiac output supplies blood to the bones. A typical long bone has three main sources: the nutrient artery, the metaphyseal and epiphyseal arteries, and the periosteal arteries.
Nutrient Artery
The nutrient artery is the main blood vessel that enters the diaphysis via the nutrient foramen. While most long bones have only one nutrient foramen, large bones, such as the femur, may have two. This...
Timing and Consequences on Behavior01:08

Timing and Consequences on Behavior

In operant conditioning, the timing of reinforcement is crucial. For animals like rats and cats, immediate reinforcement (within a few seconds) is much more effective than delayed reinforcement. For example, a food reward for a rat needs to follow within 30 seconds of pressing a bar to be effective. 
Humans, however, can respond to delayed reinforcers. We often make decisions between immediate small rewards and delayed larger rewards. This ability to delay gratification is a significant factor...
