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

patients undergoing mastectomy with axillary evacuation will be divided to four groups, Placebo group: received placebo capsule Duloxetine 30: received duloxetine 30 mg capsule Duloxetine 60: received duloxetine 60 mg capsule Duloxetine 90: received duloxetine 90 mg capsule the study medication is administered orall 2 h before surgery. Primary outcome variable: the first postoperative 24 h morphine consumption Secondary outcome: the VAS pain score measured every 4 h in the first 24 h postoperatively.

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

20 years to 70 years (ADULT, OLDER_ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

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
the first postoperative 24 h (patient controlled analgesia [PCA])morphine consumption
Time Frame: the first postoperative 24 hour
the cumulative patient controlled analgesia morphine consumption required by the patients to relieve their pain in the first postoperative 24 h
the first postoperative 24 hour

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
The intensity of pain measured by visual analogue pain scale (VAS)
Time Frame: The outcome will be assessed at 0 hour, 2 hour, 4 hour,8 hour, 16 hour and 24 hour postoperatively.
The intensity of pain measured by visual analogue pain scale (VAS) in which 0 = no pain and 10 = the maximum imaginable pain
The outcome will be assessed at 0 hour, 2 hour, 4 hour,8 hour, 16 hour and 24 hour postoperatively.
The quality of postoperative recovery, assessed by "The QoR-40 questionnaire" (the quality of recovery-40 questionnaire)
Time Frame: the questionnair will be assessed once, 24 hour postoperatively
It measures five components of patient recovery: physical comfort (12 questions), physical independence (5 questions), emotional state (9 questions), psychological support (7 questions), and pain (7 questions). The sum of each component generates an aggregate score that ranges from 40 (i.e., extremely poor quality of recovery) to 200 (i.e., excellent quality of recovery)
the questionnair will be assessed once, 24 hour postoperatively
The level of consciousness assessed by "the Modified Ramsay Sedation score"
Time Frame: the score will be measured at 8 hour, 16 hour and 24 hour postoperatively
awake levels were: I = anxious, agitated, or restless; II = cooperative, oriented, and tranquil; III = responds to command, and asleep levels were dependent on patient's response to a light glabellar tap or loud auditory stimulus; IV= brisk response; V = a sluggish response; and VI = no response)
the score will be measured at 8 hour, 16 hour and 24 hour postoperatively
The occurrence of vomiting
Time Frame: The outcome will be obtained once 24 hour postoperatively
vomiting is forceful discharge of stomach contents
The outcome will be obtained once 24 hour postoperatively

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. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
