The use of TIVA is advantageous in cases where volatile anesthesia is of high risk or is impossible, such as cases involving morbidly obese patients. [11] [12] TIVA has also been used for anesthetic delivery at sites of trauma such as serious accidents, disasters and wars. [1] The overall goals of TIVA include: [13] Smooth induction of anesthesia
Remifentanil can be administered as part of an anesthesia technique called TIVA (total intravenous anesthesia) using computer controlled infusion pumps in a process called TCI (target controlled infusion). A target plasma concentration is entered as ng/mL into the pump, which calculates its infusion rate according to patient factors like age ...
However, compare to the doses used for TIVA (total intravenous anesthesia), which is always lower than using the single anesthetics. [9] The doses of anesthetics required differ, and depend on the required duration of anesthesia, the requirements for anesthesia to volatile, expected pain of injection of anesthesia, the experience the ...

Inhaled anaesthetic agents are also frequently supplemented by intravenous analgesic agents, such as opioids (usually fentanyl or a fentanyl derivative) and sedatives (usually propofol or midazolam). Propofol can be used for total intravenous anaesthetia (TIVA), therefore supplementation by inhalation agents is not required. [45]
Twilight anesthesia is also known as twilight sleep and allows an easy awakening and a speedy recovery time for the patient. Anesthesia is used to control pain by using medicines that reversibly block nerve conduction near the site of administration, therefore, generating a loss of sensation at the area administered.
Anesthetic risk factors include the use of volatile anesthetics, nitrous oxide (N 2 O), opioids, and longer duration of anesthesia. Patient factors that confer increased risk for PONV include female gender, obesity , age less than 16 years, past history of motion sickness or chemotherapy-induced nausea, high levels of preoperative anxiety , and ...
Anesthetic overdose-caused medullary paralysis with respiratory arrest and vasomotor collapse. Pupils are widely dilated and muscles are relaxed. In 1954, Joseph F. Artusio further divided the first stage in Guedel's classification into three planes. [9] 1st plane The patient does not experience amnesia or analgesia
