February 25, 2019 updated by: Guolin Wang

Effects of Etomidate/Propofol Mixture or Propofol Monotherapy With Different Proportions on Circulation and Prognosis in Patients Undergoing General Anesthesia

The purpose of this study was to investigate the effects of different proportions of etomidate/propofol mixture and propofol alone intravenous anesthesia on intraoperative and postoperative physiological indicators and complications, and to find out the optimal use ratio of E/P mixture.

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

Propofol is one of the most commonly used intravenous anesthesia drugs clinically, the pharmacokinetic characteristics makes it very suitable for total intravenous anesthesia( TIVA), etomidate belongs to intravenous anesthesia with propofol, is a derivative of the imidazoles, its calm performance is strong, work quickly, no obvious respiratory depression, had little effects on the cardiovascular system, which, therefore, to protect the cardiovascular, maintain hemodynamic stability has a certain advantage. Our previous project showed that propofol and etomidate combined application can maintain stable hemodynamics in patients with better, reduce the occurrence of adverse reactions, can be used within 3 h of surgery anesthesia.The purpose of this study is to use propofol or etomidate/propofol mixture in combination with BIS monitoring to perform general anesthesia maintenance for patients, in order to ensure the appropriate depth of anesthesia, better maintain the hemodynamic stability of patients, reduce adverse reactions, and find the appropriate E/P mixture of the best proportion and dose.

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. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria
