Drug delivery in association with medical or surgical procedures
First Claim
1. A method of providing effective sedation and/or pain relief by a non-anesthetist without general anesthesia to a non-intubated patient during a medical and/or surgical procedure, said method comprising:
- infusing said non-intubated patient with a sedative and/or pain relieving drug that acts upon the patent'"'"'s central nervous system at a dosage that is insufficient to result in general anesthesia;
sensing at least one physiological condition of the patient during said procedure with one or more monitors selected from the following;
pulse oximeter, heartrate, blood pressure, carbon dioxide, EEG, and ventilator;
generating a signal in the event said physiological condition of said patient becomes unsafe; and
modifying said infusion of said drug so as to return said patient to a safe physiological condition.

Abstract
Disclosed are various methods and devices for facilitating medical and/or procedures that are performed without “general anesthesia,” which is also described in the specification as the state of patient “unconsciousness” resulting from a drug administered by an anesthetist or anesthesiologist. The devices safely and effectively provide and maintain drug infusions that do not push the patient into unconsciousness and/or general anesthesia. Devices according to embodiments of the invention include the use of stored parameters and/or values that correlate to drug delivery during a procedure, and a patient health monitor to measure and send signals regarding a patient health condition to a processor or other computational device.

10. A method of providing safe and effective sedation, analgesia and/or amnestic drugs to a non-intubated patient undergoing a medical procedure by a procedural physician so as to safely avoid the cost of ventilation equipment and/or an operating room, said method comprising the steps of:
-
connecting said non-intubated patient to one or more physiological monitors capable of detecting signals of ventilation suppression and/or airway obstruction; delivering said monitored signals to a logic chip having access to a memory device containing data representative of safe and/or unsafe ventilation conditions; an infusion system for infusing a drug into said patient for providing sedation, analgesia and/or amnesia, said infusion system being primarily controlled by said logic chip; comparing said monitored signals with said data on said memory device and for providing an alarm signal in the event said patient'"'"'s condition becomes unsafe; and visually and/or audibly advising said procedural physician of unsafe conditions for said non-intubated patient. - View Dependent Claims (11, 12, 13)

14. An electronic method of providing safe and effective sedation, analgesia and/or amnestic drugs to a non-intubated patient undergoing a medical procedure by a procedural physician so as to safely avoid the cost of ventilation equipment and/or an operating room, said method comprising the steps of:
-
infusing said non-intubated patient with a sedative, pain relieving and/or amnestic drug at a dosage rate sufficient to achieve all levels of sedation, but insufficient to result in general anesthesia, said drug being a short acting, fast dissipating drug; electronically sensing at least one physiological condition of the patient during said procedure; ascertaining whether said sensing reflects an adverse physiological condition; electronically generating a signal in the event of said patient is in an adverse physiological condition an adverse change in said physiological condition, controlling said infusion so as to terminate and/or reduce said infusion and permitting said infused drug to dissipate in response to said adverse physiological condition. - View Dependent Claims (15, 16, 17, 18)
