Detailed Description

To investigate the efficacy and safety of propofol combined with different doses of esketamine (ESK) for anesthesia during loop electrosurgical excision procedure (LEEP). Ninety female patients undergoing LEEP were randomly allocated to three groups: group P (2 mg/kg propofol + saline), group propofol + esketamine(PK)1 (1.5 mg/kg propofol + 0.5 mg/kg ESK), and group PK2 (1.5 mg/kg propofol + 0.25 mg/kg ESK). Parameters including mean arterial pressure (MAP), heart rate (HR), respiratory rate (RR), oxygen saturation (SPO2), and venous carbon dioxide (PvCO2) were recorded. Additionally, the need for supplemental propofol, jaw thrust maneuver or ventilation, postoperative awakening time, and adverse reactions were assessed.

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

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. 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.
