Q

What happens at the supracristal plane?

A

Supracristal plane: Horizontal plane through the iliac crest at the L4 vertebral level.

How is pain by inflammation characterised?
* Constant pain (aching) * Made worse by movement * Persists until inflammation subsides + associated with somatic sensation.
50
How is pain characterised by obstruction?
* Colicky pain (gripping) * Fluctuates in severity * Move to try and get comfortable
51
What is the consequence of prolonged obstruction of a hollow viscus?
Can cause distention- constant stretching pain, that is different from inflammation and not colicky There is a risk of ischaemia
52
What is the definition of colicky pain?
Colicky pain describes an intermittent form of pain that begins and stops abruptly due to muscular contractions of a hollow tube in an attempt to relieve the obstruction

What is colicky pain associated with?
Accompanied by sweating and vomiting + visceral sensation (referred centre)

How is ureteric colic pain characterised?
Associated with intense and fluctuating pain
56
How is biliary colic pain characterised?
Refers to constant intense pain for a prolonged period of time until relaxing
57
How is intestinal colic pain characterised?
• Intestinal colic refers to frequent contractions of pain, although the intensity of pain is comparatively less.
