Comparison of Pain Therapeutic Effects After Benign Mastectomy (COPTEAM)

March 30, 2009 updated by: Nanjing Medical University

Clinical Comparison of Postoperative Pain Therapeutic Effects After Benign Mastectomy

With the incremental trend of benign breast tumor, the surgical process of mastectomy was proceeded too much every day, especially in the Maternal Health Care Hospital, but whether the investigators can find another way to relieve the postoperative pain after such an operation is still unknown. The investigators hypothesized that the pain from the relatively small surgery may not be significant compared to different treatments, even if no drug was delivered to them. The investigators are enrolling patients who underwent mastectomy from benign breast tumor, and are observing the analgesic effects of different drugs.

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

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.

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).

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
Time Frame
Visual analog scale (VAS) rating of pain
Time Frame: 0-24h after surgeries
0-24h after surgeries

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
Time Frame
VAS rating of sedation
Time Frame: 0h to 24h after the end of the operation
0h to 24h after the end of the operation
Overall VAS rating of satisfaction with analgesia
Time Frame: 24 h after operation
24 h after operation
Incidence of side effects
Time Frame: From the initiation of analgesia (0 h) to the end of the study (24 h postoperative)
From the initiation of analgesia (0 h) to the end of the study (24 h postoperative)

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.
