What are the different drugs used in TIVA and their doses?

TIVA involves the administration of intravenous drugs in a permanent or constant manner, providing amnesia, analgesia, and muscle relaxation.
The protocols for TIVA include sedative-hypnotic (e.g., propofol) combined with a potent analgesic (e.g., remifentanil), producing sedation, analgesia, and muscle relaxation.
The use of TIVA has been shown to reduce the need for analgesics in the postoperative period in patients with traumatic injuries compared to those using inhalational anesthesia.
Examples of TIVA include fentanyl + propofol, remifentanil + propofol, fentanyl + propofol + dexmedetomidine, remifentanil + propofol + dexmedetomidine, fentanyl + propofol + lidocaine, fentanyl + dexmedetomidine + ketamine, and propofol + midazolam + ketamine.
