Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Clinically common non-systemic anesthesia mainly includes surface anesthesia, local immersion anesthesia, nerve block, regional blocking, intravertebral anesthesia. Patients under non-general anesthesia surgery, is still in a more sober state, easily due to external factors and increase the psychological and mental burden, even if the ideal anaesthetic effect can be achieved, but for autonomic nerve activities can not be completely and effectively eliminated. Hydrochloric acid right-metomidine is an alpha2-adrenaline receptor agonisant developed by Orion Pharma (Finland) and Abott (Usa) in collaboration. Unlike other sedative hypnotic sedatives, hydrochloric acid right metamine produces a sedative hypnotic effect by acting on the blue spot nuclear alpha2 receptor and the inflammatory endogenous sleep-stimulating pathway, allowing the patient to maintain a natural sleep state of non-fast eye III, which is characterized by the patient being stimulated or speech-altered, and does not produce respiratory inhibition during sedative hypnosis. In addition to the sedative effect, the right metomisurein also has anti-anxiety, reduce stress response, stable hemodynamics, analgesic, inhibitsalival secretion, anti-cold and diuretic function, and other sedative analgesic drugs when used with good synergy, can significantly reduce the use of other sedative analgesic drugs.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Changes in the OAA/S score of the subject during the study medication.
Time Frame: 15min after giving the drug, every five minutes during anesthesia
At least 15 minutes before anesthesia, the study drug was given sedation according to the dosing schedule. At the end of the loading dose of the study drug, an alertness/sedation score (OAA/S) was performed, and then it entered the maintenance dosing phase, which was performed every 5 minutes until the end of the operation OAA/S score. OAA/S≤4 means that the required level of sedation has been reached, and anesthesia can be performed after starting the study drug for ≥15 minutes and reaching the required level of sedation. During the administration of the study drug, OAA/S ≤4 should always be maintained.
15min after giving the drug, every five minutes during anesthesia
