TIVA is one way of achieving this, as the avoidance of volatile agents during general anaesthesia is associated with a more rapid emergence and less side effects. TIVA may be achieved with a single agent such as propofol for shorter procedures, or can be combined with other agents. The specific combination of medications to achieve TIVA will be dependent on many factors, and should take into account individual patient needs including surgical requirements to reflect the individual needs of patients and the planned surgical procedure. A sufficient plane of anaesthesia can be achieved through either continuous infusion or bolus dosing, depending on the length of the procedure to be performed.
In comparison to inhaled volatile agents, TIVA has the advantages of:
- Significantly less postoperative nausea and vomiting (PONV) with the use of propofol
- Faster emergence from anaesthesia
- Significant reduction of emergence delirium in paediatric patients
- Reduction of cognitive impairment and delirium in elderly patients
- Reduced airway irritation in all ages, including post extubation cough
- Half the risk of laryngospasm and bronchospasm in paediatric patients
- Maintenance of cardiac functioning, especially notable in elderly patients who are able to maintain lung perfusion and have less cardiac depression
- Suitable for use in patients with a potential/confirmed risk of malignant hyperthermia
These benefits of TIVA, particularly with the utilisation of propofol, have enhanced the options available for general anaesthesia. Patients who are undergoing short procedures or investigations as day only patients are often able to be discharged home faster, as the side effects are reduced.
