Balanced anesthesia
Balanced anesthesia is an anesthetic method for surgical patients during their operation, which was proposed by John Lundy in 1926. The purpose of balanced anesthesia is not only to be less dangerous than using only one drug for general anesthesia but also to minimise the potential adverse side effects which may be caused by the anesthetic agents. The concept of balanced anesthesia is that of applying two or more medications or techniques in order to ease pain, relax the muscles, and have autonomous reflexes suppressed in the patient. In other words, it is an anesthesia method to maintain stable vital signs. There are numerous factors that come into play when the anesthetist decides to use this method of anesthesia. These factors include, but are not limited to: patients' major organ functions, general condition and compensatory capacity. By making use of adequate types and appropriate amounts of agents and accurate anesthesia methods, the anesthetist will promote a successful, safe, and efficient surgery. Principles of pharmacokinetics The scope of pharmacodynamics is the effects caused on the body by a medicine. However, the distribution of medicine, clearance and the concentration of medicine in tissue, blood or plasma are part of the pharmacokinetic features
