CRIs can be used with which two approaches?

• A. PIVA or TIVA
• B. PIVA or MAC-sparing
• C. MAC-sparing or Analgesia
• D. Analgesia or No Analgesia

Answer: (A)

CRIs are used to provide continuous analgesia that can be combined with both intravenous anesthesia strategies. They pair with partial intravenous anesthesia, where some inhaled agent is used alongside IV anesthetics, and with total intravenous anesthesia, where anesthesia relies entirely on IV agents. Adding a CRI helps reduce the amount of inhaled agent needed and can lower overall opioid requirements, improving analgesia and recovery. The other terms listed aren’t anesthesia delivery approaches, so they don’t describe the two methods CRIs are used with. Therefore, the two approaches are partial intravenous anesthesia and total intravenous anesthesia.
