10. Regional and local anesthesia Flashcards
Regional anesthesia types
- Local anesthesia
- Nerve blocks
- Neuraxial anesthesia (spinal,/epidural)
Advantages of SPA over GA
- Less cardiorespiratory complications
- Less bleeding
Advantages of GA over GA w/EDA
- Thromboembolism risk dec.
- Mortality dec. (30%)
