Transition From Acute to Chronic Pain After Inguinal Hernia, Hysterectomy and Thoracotomy: Analysis of Risk Factors and Association With Genetic Polymorphisms

Transition From Acute to Chronic Pain After Inguinal Hernia, Hysterectomy and Thoracotomy : Analysis of Risk Factors and Association With Genetic Polymorphisms

The treatment of postoperative pain continues to be inadequate in the investigators practice setting.

Inadequate pain treatment not only contributes to postoperative complications in the short term but can also be a factor that favors the development of chronic postoperative pain and diminishes long-term quality of life. Risk factors that can lead to a transition to chronic pain need to be analyzed.

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 and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Sampling Method

Non-Probability Sample

Study Population

All spanish patients who undergo scheduled surgery of one of the following types: inguinal herniorrhaphy, hysterectomy, toracothomy.

Description

Inclusion Criteria:

  • Patients with given inform consent, aged mor than 18 years, who undergo scheduled surgery of one of the following types: inguinal hernia (men), hysterectomy, thoracotomy (men).

Exclusion Criteria:

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
Evaluation of chronic postsurgical pain.
Time Frame: After 3 and 12 months of surgery.
After 3 months a physical examination will take place and after 12 months a follow-up will be reported by phone.
After 3 and 12 months of 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
Predictive factors of chronic postsurgical pain.
Time Frame: After 3 and 12 months of surgery.
Preoperative (psychological factors, preoperative pain, pharmacologic treatment) intraoperative (surgical technic, type of anaestesia) and postoperative(posoperative pain, surgical complications and treatment of postoperative pain).
After 3 and 12 months of surgery.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

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.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit).
