Effects of Sevoflurane and Propofol on Optic Nerve Sheath Diameter During Laparoscopic Gynecologic Surgery

June 19, 2020 updated by: Weilian Geng, Obstetrics & Gynecology Hospital of Fudan University

Randomized,Double-Blind Trial A Comparative Analysis of the Effects of Sevoflurane and Propofol on Optic Nerve Sheath Diameter During Steep Trendelenburg Position and Pneumoperitoneum for Laparoscopic Gynecologic Surgery

Intracranial pressure（ICP) increases during laparoscopic gynecologic surgery increase (ICP) and may alter optic nerve sheath diameter(ONSD).This study measures ONSD in different team because sevoflurane and propofol have different effects on ICP.Half of participants will receive sevoflurane anesthesia,while the other half undergo propofol anesthesia.

Study Overview

Status

Indicates the current recruitment status or the expanded access status.

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

Due to the anatomical and physiological characteristics of optic nerve sheath ,ONSD increases when ICP rises.

Sevoflurane and propofol have different effects on ICP.When sevoflurane concentration >1.1 minimum alveolar concentration（MAC),ICP increases because of cerebral vasodilatation；on the other hand ,propofol constricts the blood vessels and ICP decreases.

ICP increases during laparoscopic gynecologic surgery because of steep Trendelenburg position and pneumoperitoneum .

Meanwhile,sevoflurane affects self regulation of cerebral blood flow on the way of dose dependent,but propofol has no effects on self regulation of cerebral blood flow.

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.

Ages Eligible for Study

18 years to 60 years (Adult)

Accepts Healthy Volunteers

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 of ultrasonographic optic nerve sheath diameter
Time Frame: from the time when patients enter into operation room to the time when the surgery ending
different time including pre-anesthesia, after intubation,every 15 minutes in the first hour after beginning of surgery, every hour when one hour after surgery beginning,surgery ending.
from the time when patients enter into operation room to the time when the surgery ending

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
