Analgesia and Pain Management01:25

Analgesia and Pain Management

763
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...

Nociception01:44

Nociception

29.2K
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.

Methods of Documentation VI: Case Management Model

619
The case management model is a multidisciplinary approach that involves healthcare professionals from diverse disciplines, such as physicians, nurses, therapists, social workers, and pharmacists, working collaboratively to address the various needs of patients. Each healthcare professional brings unique expertise and perspectives, contributing to a more comprehensive understanding of the patient's condition and tailoring treatment plans accordingly.
For example, a patient with a chronic...

Chronic Pancreatitis I: Introduction

140
The pancreas, an elongated and flat gland situated behind the stomach, serves a vital function in digesting food and managing blood sugar levels.
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...

Pain01:20

Pain

588
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...

Methods of Documentation II: POMR

1.0K
The Problem-Oriented Medical Record (POMR) revolutionized medical record-keeping by introducing a systematic approach focusing on the patient's problems rather than merely listing symptoms. Dr. Lawrence Weed's introduction of this method in the 1960s marked a significant advancement in medical documentation. The POMR framework consists of four key components: the database, problem list, plan of care, and progress notes.

Summary
This summary is machine-generated.

Chronic pain is not always a progression of acute pain. A new model suggests chronic pain develops from accumulated events, offering better prevention and treatment strategies for persistent pain.

Area of Science:

  • Pain research
  • Neuroscience
  • Clinical pain management

Background:

  • Current focus on 'chronification' of acute pain to explain chronic pain.
  • Limited success in preventing 'chronification' post-surgery.
  • Need for alternative models to understand chronic pain origins.

Purpose of the Study:

  • To challenge the 'chronification' model of chronic pain.
  • To present an alternative model for chronic pain development.
  • To improve prevention and treatment strategies for chronic pain.

Main Methods:

  • Literature review using PUBMED.
  • Analysis of data from the HUNT pain examination study.

Main Results:

  • Less than 25% of chronic pain patients link onset to an acute event.
  • Proposes a 'priming' theory: accumulation of predictive events.
  • Chronic pain may arise from a continuum of factors, not solely acute pain.

Conclusions:

  • The 'chronification' model is insufficient for all chronic pain cases.
  • Plastic changes in pain pathways form a continuum.
  • Acute pain events are potential tipping points, not the sole cause.
