Anesthetics and ICU section of the Zero to Finals Surgery book.
The International Association for the Study of Pain (IASP)
published a definition of pain in 2020. As pain is a subjective
experience, there are no simple reliable ways to objectively measure
the pain that somebody is experiencing. Instead, we measure pain by
asking the patient about their perception of it. Referred pain occurs
when someone feels pain away from the actual site of tissue
damage. Neuropathic pain arises from abnormal functioning or
damage to the sensory nerves, which results in pain signals
transmitting to the brain. The Analgesic Ladder was originally
developed by the World Health Organization (WHO) to help
manage cancer-related pain. The concept is that patients with mild
pain start with the first step on the ladder, and if their pain is more
severe or doesn't respond to the lower steps, higher steps can be
used until their pain is adequately managed. Other medications may
be combined with the ladder to enhance its effect.
A patient is currently receiving 30 milligrams of modified release
morphine every 12 hours for breakthrough pain. Additionally, the
patient is receiving 60 milligrams of background morphine every 24
hours. In the case of a rescue dose, the patient would receive one-
sixth of the 24-hour background dose. Patient-controlled analgesia
involves intravenous infusion of strong opioids like morphine,
oxycodone, or fentanyl. According to the NICE guidelines on
chronic pain, updated in April 2021, chronic pain can be separated
into chronic primary pain and chronic secondary pain. It is estimated
that up to 50% of adults in the UK are affected by chronic pain.
Chronic pain is diagnosed when pain has been present or reoccurs in
