Abstract
Abstract An apparatus for total intravenous anesthesia includes at least one supply and infusion pump for an intravenous anesthesia agent carried by the apparatus housing, and at least one monitor for monitoring the characteristics of the patient during the total intravenous anesthesia. The at least one intravenous anesthesia agent preferably includes a first intravenous anesthesia agent, and more preferably, an analgesic, having a relatively quick offset so that the effects wears off relatively quickly upon stopping intravenous infusion. For monitoring the patient, the apparatus preferably includes at least one of an electrocardiogram, a blood oxygen monitor, a blood carbon dioxide monitor, inspiration/expiration oxygen, inspiration/expiration carbon dioxide, a blood pressure monitor, a pulse rate monitor, a respiration rate monitor, and a patient temperature monitor, for example. The first intravenous anesthesia agent may be an esterase metabolized opioid, such as remifentanil. A second supply of a second intravenous anesthesia agent carried by the housing may also be included. The second supply may be another anesthesia agent, such as propofol, for example. Method aspects of the invention are also disclosed.
