other nonpharmalogical measures
Immobilization and rest Cognitive-behavioral interventions Distraction Progressive muscle relaxation Guided imagery Hypnosis Therapeutic touch Humor Journaling
pharmalogical measures
Nonopioid analgesics NSAIDs Acetaminophen Opioid analgesics Includes IV, IM, transdermal, and epidural forms Client-controlled analgesia pumps
patient controlled analgesia
Safe method for delivery of post-op and cancer pain management.
Allows client to self-administer opioids with minimal risk of overdose.

topical pain meds
