how does the SNS respond
overproduces hormones –> ACTH, cortisol, ADH, insulin, glucagon, etc

increased cardiac workload and O2 demand
how is the respiratory system affected
increased rate to meet O2 demands
how does the musculatory system respond to pain
muscle spasm, tension, fatigue
how does the GU respond to pain
activation of the renin-angiotensin system
how does the Gi respond to pain
slow gastric emptying, increased secretions, metabolism slowed
what are the 2 types of pharmacologic management of pain
- non-opiod analgesics
- opiod analgesics
non-opioid analgesics
Tylenol, NSAIDs, TOPICAL ANESTHETICS
