CHAPTER 15 Pain Management
Various individuals can experience different levels of pain with the same injury.
Researchers have sought to explain this phenomenon. The gate control theory pos-
tulates that there is a “gate” in the spine which controls the impulses from the finger
on the hot stove to the brain. The brain controls this gate to allow total or partial sig-
nals through. However, the interpretation is based on current emotions, memories,
expectations, ideals, and cultural biases. If your mind is busy elsewhere, the pain
may be somehow lessened, for example, the Lamaze experience through labor and
childbirth. This is one of the more popular pain theories, among others.
Emotional pain can produce many symptoms, as varied in their presentation as
the etiology of the pain.
Pain scales are useful tools to assess severity of pain and quality of life. They
will help the patient to accurately assess the pain and the impact it is having. Pain
scales often are measured on a Likert scale, from 0 (no pain) to 10 (the worst pain
ever). The Wong pain scale for children, uses a happy smiling face to a sad, tear-
ful one. Another useful tool is a pain diary, in which the patient records severity,
location, activity at the time, precipitating factors, and what, if anything, relieved
the pain. It is a helpful tool to asses worsening or alleviating pain and also reac-
tions to pain medications.
