About this study

Official title: Prospective Randomized Clinical Trial to Evaluate the Use of Paravertebral Blocks in Reconstructive Breast Surgery

Primary Objective:

To determine whether the use of a paravertebral block in patients undergoing reconstructive surgery for breast cancer results in decreased immediate post-operative pain compared with patients having only general anesthesia.

Secondary Objectives:

  1. To determine whether the use of a paravertebral block in patients undergoing reconstructive surgery for breast cancer results in decreased post-operative pain in the first 24 hours after surgery compared with patients having only general anesthesia.
  2. To determine whether the use of a paravertebral block in patients undergoing reconstructive surgery for breast cancer results in decreased post-operative nausea and vomiting in the first 24 hours as compared with patients having only general anesthesia.
  3. To determine whether the use of a paravertebral block in patients undergoing reconstructive surgery for breast cancer results in a decreased length of hospital stay compared with patients having only general anesthesia.
Read the detailed description

Paravertebral Blocks and General Anesthesia The use of a paravertebral block involves injecting local anesthesia (a numbing medicine) into the patient's back to numb specific areas (the breast[s] for this study) for surgery.

General anesthesia is medicine that is used to put patients to sleep so that there is no feeling of pain.

Study Groups:

If you are found to be eligible to take part in this study, you will be randomly assigned (as in the toss of a coin) to 1 of 2 groups. You will have an equal (50/50) chance of being assigned to either group.

Participants in one group will receive a paravertebral block (the local anesthetic ropivacaine) plus general anesthesia.

Participants in the other group will receive general anesthesia (propofol, desflurane, and fentanyl) without a paravertebral block.

Drug Administration:

If you are assigned to receive the paravertebral block plus general anesthesia, you will have a paravertebral block placed just before surgery begins. Ropivacaine will be given by injection into the paravertebral space along the spinal canal.

If you are assigned to receive general anesthesia without a paravertebral block, you will be given propofol, desflurane, and fentanyl by vein over 1-4 hours during surgery.

Participants in both groups will receive promethazine, famotidine, and dexamethasone at the start of surgery to help decrease or eliminate nausea and vomiting that may occur after surgery.

Follow-up:

After your surgery is complete, before you leave the hospital, you will have the following evaluations:

  • You will be asked how you are feeling so that the study doctor can determine how much medication you may need for pain and nausea as well as how long your hospital stay may need to be. You may be given fentanyl and dilaudid for pain and ondansetron and promethazine for nausea.
  • You will also be asked about your satisfaction with the anesthesia. You will be asked these questions within the first hour, between 1 and 3 hours, and between 3 and 6 hours after surgery. Once you are discharged from the hospital, study staff will contact you by phone or talk with you when you return for a visit (at 18 -22 hours and 1 week after surgery) to ask these questions. It will take about 3-5 minutes to ask these questions each time.

Length of Study:

Your participation in this study will be over after the 1 week follow-up telephone call.

This is an investigational study. Paravertebral blocks and general anesthesia are FDA approved and commercially available. Up to 89 patients will take part in this study. All will be enrolled at M. D. Anderson.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Proportion of Participants With No Pain Immediately After Surgery

    Pain assessed using a verbal numeric rating scale (NRS) scored by numeric integers, with scores of 0-10 where 0 is no pain and 10 is the worst pain. Pain evaluated within the first hour, between 1 - 3 hours, between 3 - 6 hours post-operatively. Additional reporting planned for following morning (18 - 24 hours post-operatively).

    Measured: Starting immediately after surgery, every 2 hours till the 6th hour following surgery

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Paravertebral Block, Propofol and Fentanyl in people with Breast Cancer, run by M.D. Anderson Cancer Center at 1 site in United States.

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 5 inclusion and 6 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 13 Apr 2015. 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 United States. 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.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 13 Apr 2015). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Proportion of Participants With No Pain Immediately After Surgery (time frame: Starting immediately after surgery, every 2 hours till the 6th hour following surgery). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 13 Apr 2015.
