What does TIVA stand for in CRI terminology?

• A. Total Intravenous Anesthesia
• B. Total Inhalation Anesthesia
• C. Temporary Intravenous Analgesia
• D. Transvenous Intraoperative Analgesia

Answer: (A)

Total Intravenous Anesthesia means using intravenous drugs alone to induce and maintain anesthesia, rather than inhaled gases. In CRI practice, anesthesia is delivered as a continuous rate infusion (or a target-controlled infusion) of agents such as propofol, often with an opioid, to keep a stable unconscious state throughout the procedure. This approach relies on maintaining consistent blood levels of the anesthetic through IV administration, avoiding volatile inhaled agents. The other terms describe inhalation anesthesia, analgesia-only strategies, or combinations that don’t reflect the IV-only approach used in TIVA.
