Evidence-based slide

What evidence based conclusion was found with the study “Perioperative systemic magnesium to minimize postoperative pain”?

A

a lot of these procedures used Fentanyl, Morphine PCA, Toradol, Tramadol and Meperadine as part of their pain pathway (not specific multimodal)

they did test for early and late pain at rest and movement

further findings: there is significant pain relief or pain control or reduction at intraop and post-op vs intraop only

also cited in their findings that there are opioid side effects of dizziness headache and post op nausea and vomiting
