Post-discharge Pain After Breast-surgery Treated by Paravertebral Block
An observational study of Mastectomy, Segmental and Regional Anesthesia, run by Samuele Ceruti at 1 site in Switzerland.
Trial summary
Breast surgery is known being associated to a high risk of persistent post-operative pain, which has been related, among other factors, to a poorly treated acute pain. Paravertebral block has been successfully employed for anesthesia and analgesia after breast surgery, however its impact on persistent post-operative… Read more about this study

About this study
Official title: Persistent Post-discharge Pain After Breast Surgery With Paravertebral Block: Incidence, Characteristics and Consequences
Breast surgery is known being associated to a high risk of persistent post-operative pain, which has been related, among other factors, to a poorly treated acute pain. Paravertebral block has been successfully employed for anesthesia and analgesia after breast surgery, however its impact on persistent post-operative pain has rarely been investigated. Aim of this study is to assess prevalence, characteristics and consequences of post-discharge pain and its correlation to the incidence of persistent post-operative pain development in a continuous cohort of patients undergoing breast surgery with a paravertebral block.
Investigators designed a prospective, observational study on a continuous cohort of adult patients undergoing breast surgery with a standardized thoracic paravertebral block performed before general anesthesia induction. Patients were subsequently interviewed 6 months after hospital discharge in order to assess the incidence, features and duration of post-discharge pain.
Read the detailed description
Breast cancer is the most frequent cancer in women, with an incidence of more than one million new cases per year. In the majority of cases surgery is part of the treatment and prognosis has progressively improved during last years. Attention is thus being increasingly focusing on these patients' quality of life and chronic postsurgical pain, defined as pain in the area of surgery lasting beyond 3 month from the operation, has emerged as a frequent long-term complication, with prevalence up to 60%. This often-disabling condition has been shown to significantly affect cancer survivors' quality of life and to have a heavy economic impact on the healthcare system.
Many potential risk factors have been proposed for the development of chronic post-breast surgery pain. A Cochrane systematic review has addressed the role of regional anesthesia in preventing the development of chronic postoperative pain, suggesting that "paravertebral block may reduce the pain after breast cancer surgery in about one out every five women treated", these results being however weakened by the often poor quality and inadequate power of the studies available. Many predictors of chronic postoperative pain have been identified, one of them being a poorly treated acute pain; in this perspective, regional anesthesia could possibly play a role in preventing nervous system remodeling with resultant hyperalgesia, allodynia and sustained wound pain.
Even if chronic postoperative pain has been progressively recognized as an issue after breast cancer surgery, its link to poorly treated acute postoperative pain and post-discharge pain (PDP) has been poorly investigated. Single shot paravertebral block is an effective technique to provide both anesthesia and good analgesia after breast surgery, but its benefits duration is still debated.

Phone questionnaireOther
Patients were contacted by phone 6 months after surgery and, after oral consent, a standardized questionnaire was administered in order to inquiry about the length and nature of post-operative pain, the incidence of post-discharge pain, its characteristics, its impact on daily life, its treatment and its rate of chronicity

What is being measured
The primary outcome is the main question the study is designed to answer.
Post-discharge pain
Primary endpoint of this study is to assess the incidence of post-discharge pain in a cohort of patients undergoing breast surgery with a single shot thoracic paravertebral block.
Measured: 6 months post-surgery
Secondary outcomes (2)
Pain characteristics
Secondary endpoints is to characterize this post-discharge pain in terms of pain characteristics, evaluated by Numerical Rating Scale (NRS, from 0 intended as no pain, to 10 as maximal pain), on patient daily life after discharge home.
Measured: 6 months post-surgery
Pain impact
Secondary endpoints is to characterize this post-discharge pain in terms of pain impact on patient daily life after discharge home, intended as capable to impact especially on a) work, b) leisure or c) sleep.
Measured: 6 months post-surgery

Questions about this trial
What is this clinical trial studying?
An observational study of Mastectomy, Segmental and Regional Anesthesia, run by Samuele Ceruti at 1 site in Switzerland.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 7 Aug 2018. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Switzerland. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Post-discharge pain (time frame: 6 months post-surgery). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03618459, which also lists 11 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 7 Aug 2018.
