Defining General Anesthesia
The term anesthesia is defined as “loss of sensation with or without loss of consciousness”. It is the use of medicine(s) to prevent pain during surgery and other procedures. Many associate the term “anesthesia” solely with general anesthesia. However, it is important to understand that there are various degrees of central nervous system depression, with general anesthesia being the largest degree.
Sedation can be defined as “drug induced state of drowsiness resulting from mild to moderate central nervous system depression”. General anesthesia can be defined as “controlled and reversible depression of the central nervous system to elicit unconsciousness and eliminate pain during periods of surgical stimulation”. The most important indication is that when a patient is sedated, they can still respond to noxious stimuli, but with general anesthesia, there is no response to noxious stimuli.
Total Intravenous Anesthesia
Total Intravenous Anesthesia (TIVA) can be defined as a technique of general anesthesia using a combination of agents given by the intravenous route without the use of inhalation agents. It has become a popular and practical choice for anesthesia.
TIVA may be achieved with a single agent such as Propofol for shorter procedures or can be combined with other agents. The combination of the medications to achieve TIVA will be dependent on many factors and should be considered based upon individual patient needs including surgical requirements to reflect the individual needs of patients and the planned surgical procedure.
- Improved hemodynamic stability
- Reduced post-operative nausea
- Adjustability and reversibility of the drugs
- Less dysphoric recoveries
- Improved analgesia and improved stability of anesthetic gases during procedures
