The Effect of Anesthetic Technique on VEGF-C and PGE2

January 21, 2020 updated by: General Hospital of Ningxia Medical University

Effect of Anesthetic Technique on Serum Vascular Endothelial Growth Factor C and Prostaglandin E2 in Women Undergoing Surgery for Uterine Leiomyomas

The purpose of this study is to verify the effect of anesthetic technique on the change of postoperative serum vascular endothelial growth factor C and prostaglandin E2, and to explore the potential impact of the anesthetic technique on leiomyomas recurrence and growth after the surgery of abdominal myomectomy.

Study Overview

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

Uterine leiomyomas is the most common benign tumor of uterus, the most common tumor in women as well. Like many other forms of tumor, it requires an independent blood supply to enlarge. This process, angiogenesis, is mediated by vascular endothelial growth factor C (VEGF-C) and prostaglandin E2 (PGE2). Several studies have confirmed that VEGF-C has a high level in patients with uterine leiomyomas, which has also been demonstrated that it was related to occurrence and growth of uterine leiomyomas because it's capable of promoting angiogenesis, mitogenic, and vascular permeability-enhancing activities. Also, some researchers suggested that suppression of prostaglandin synthesis (including PGE2) via cyclooxygenase type-2 (COX-2) enzyme inhibition may reduce the incidence of some tumor. The aim of this study is to verify the effect of anesthetic technique on the change of postoperative serum VEGF-C and PGE2, and to explore the potential impact of the anesthetic technique on leiomyomas recurrence and growth after the surgery of abdominal myomectomy.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.
44

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 65 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

Female

Description

Inclusion Criteria:

  • The patients with leiomyomas requiring abdominal myomectomy, aged 18-65 year and American Society of Anesthesiologists (ASA) physical status I or II.

Exclusion Criteria:

  • The patients who had a history of surgery within the preceding two weeks, a history of blood transfusion and a history of coronary artery disease, any contraindication to spinal anesthesia or opioid analgesia.

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
Change of vascular endothelial growth factor C before anesthesia and at 48 hours after surgery
Time Frame: Before anesthesia and at 48 hours after surgery
Blood samples were sampled before anesthesia and at 48h after surgery for the serum VEGF-C，which were analyzed by using enzyme linked immunosorbent assay (ELISA).
Before anesthesia and at 48 hours after surgery
Change of prostaglandin E2 before anesthesia and at 48 hours after surgery
Time Frame: Before anesthesia and at 48 hours after surgery
Blood samples were sampled before anesthesia and at 48h after surgery for the serum PGE2，which were analyzed by using enzyme linked immunosorbent assay (ELISA).
Before anesthesia and at 48 hours after surgery

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
Time Frame
Visual analog scale (VAS) pain scores
Time Frame: at 2h, 4h, 8h, 12h, 24h and 48h after surgery
Visual analog scale (VAS) pain scores were used to evaluate postoperative pain at 2h, 4h, 8h, 12h, 24h and 48h after surgery by the anesthetist
at 2h, 4h, 8h, 12h, 24h and 48h after surgery

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date.
