Abstract

Abstract A method and system of administering a dissociative unconscious type of anesthesia are disclosed. The method and system are designed for use in office surgical units and outpatient facilities. Administration by a nurse or a physician without anesthesia training can be done with minimum danger to the patient and minimum recovery time. The method and system utilizes the intravenous titration method of administration of a combination of drugs by which the patient is placed in a dissociative, unconscious state and maintained in this state until completion of the procedure, at which time the effect of the drugs is reversed by other drugs as desired. The intravenous anesthesia is supported by infiltration of a local anesthetic, such as Xylocaine. The combination of drugs include the basal hypnotic diazepam (Valium), a dissociated unconsciousness and general analgesia phencyclidine (Ketamine) and the narcotic analgesic Nisentil. The effects of the anesthetic can be reversed by the person administering the anesthesia as soon as their desired purpose has been accomplished.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 152 words
A method of inducing a dissociative, unconscious type of anesthesia for surgical procedures which is safe and capable of being used in an office and being administered by a nurse or physician without anesthesia training, the process allowing a minimal recovery period for the patient, comprising: administering a therapeutic dose of an anti-cholinergic agent intravenously to stabilize heart action, reduce and prevent laryngeal spasm, administering intravenously a sufficient amount of the basal hypnotic diazepam (Valium) in 1 to 3 mg. increments up to 10 mg. to relieve patient stress reaction, administering intravenously by titration a dosage of from 25 to 50 mg. of a phencyclidine derivative at the rate of 1 to 3 mg. a minute to induce a state of dissociation in the patient without rendering the patient unconscious, and administering by intravenous titration 10 to 40 mg. of the analgesic alphaprodine at the rate of about 1 mg. per minute.
Claim 2
Independent Claim 152 words
A method of inducing a dissociative, unconscious type of anesthesia for surgical procedures which is safe and capable of being used in an office and being administered by a nurse or physician without anesthesia training, the process allowing a minimal recovery period for the patient, comprising: administering a therapeutic dose of an anti-cholinergic agent intravenously to stabilize heart action, reduce and prevent laryngeal spasm, administering intravenously a sufficient amount of the basal hypnotic diazepam (Valium) in 1 to 3 mg. increments up to 10 mg. to relieve patient stress reaction, administering intravenously by titration a dosage of from 25 to 50 mg. of a phencyclidine derivative at the rate of 1 to 3 mg. a minute to induce a state of dissociation in the patient without rendering the patient unconscious, and administering by intravenous titration 10 to 40 mg. of the analgesic alphaprodine at the rate of about 1 mg. per minute.
Claim 3
Dependent Claim 26 words
The method of claim 1 including potentiation of the sedative effects of the phencyclidine derivative by intravenous injection of 6 to 25 mg. promethazine hydrochloride (Phenergan).
Claim 4
Dependent Claim 47 words
The method of claim 1 including reversing the effect of the intravenous anesthesia after completion of the surgical procedure or as necessary for respiratory distress or to relieve confusion or excessive drowsiness by intravenous injection of from 1 to 2 mg. at a slow rate of Antilirium.
Claim 5
Dependent Claim 27 words
The method of claim 1 wherein a therapeutic amount of Seconal is administered orally to the patient with Combid prior to any infusion of the other drugs.
Claim 6
Dependent Claim 24 words
The method of claim 1 including supporting the intravenous anesthesia by infiltration of Xylocaine as soon as the phencyclidine takes effect in the patient.
Claim 7
Dependent Claim 23 words
The method of claim 1 wherein Inapsine is injected intravenously at a dosage of 1/2 to 1 cc as a substitute for Valium.
Claim 8
Dependent Claim 21 words
The method of claim 1 including the intravenous injection of 0.2 to 0.6 mg. Narcan during or after the surgical procedure.
