About this study

Official title: Lidocaine Patch for Adjunct Analgesia for Postoperative Cesarean Birth Patients

Randomized control trial evaluating use of lidocaine vs placebo patch for post-operative cesarean incision pain.

Read the detailed description

The purpose of this study is to determine if lidocaine patches decrease post-operative pain associated with cesarean births. While the Lidoderm lidocaine patch has been FDA approved for the treatment of skin pain, it has not been studied in women undergoing cesarean birth who experience postoperative pain. Even though this medication has been used in post-operative pain in published studies, the use of this medicine under these circumstances is still considered experimental. A lidocaine patch may provide added benefit for pain control in addition to standard medicines participants would receive after surgery, such as spinal, intravenous, and oral pain medications following cesarean delivery.

What is being measured

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

  1. 12-hour Postoperative Pain Scores

    To determine if lidocaine patch is superior to placebo as an adjunctive therapy for acute postoperative pain. Average pain score in women who have undergone cesarean delivery at 12 hours postoperatively. Measured using a Visual Analog Scale (VAS), a scale which measures pain from 0 to 100 with 0="no pain" and 100="the worst pain you have ever felt".

    Measured: Postoperative (12 hours)

  2. 24-hour Postoperative Pain Scores

    To determine if lidocaine patch is superior to placebo as an adjunctive therapy for acute postoperative pain. Average pain score in women who have undergone cesarean delivery at 24 hours postoperatively. Measured using a Visual Analog Scale (VAS), a scale which measures pain from 0 to 100 with 0="no pain" and 100="the worst pain you have ever felt".

    Measured: Postoperative (24 hours)

  3. 36-hour Postoperative Pain Scores

    To determine if lidocaine patch is superior to placebo as an adjunctive therapy for acute postoperative pain. Average pain score in women who have undergone cesarean delivery at 36 hours postoperatively. Measured using a Visual Analog Scale (VAS), a scale which measures pain from 0 to 100 with 0="no pain" and 100="the worst pain you have ever felt".

    Measured: Postoperative (36 hours)

  4. 48-hour Postoperative Pain Scores

    To determine if lidocaine patch is superior to placebo as an adjunctive therapy for acute postoperative pain. Average pain score in women who have undergone cesarean delivery at 48 hours postoperatively. Measured using a Visual Analog Scale (VAS), a scale which measures pain from 0 to 100 with 0="no pain" and 100="the worst pain you have ever felt".

    Measured: Postoperative (48 hours)

Secondary outcomes (1)
  1. 5-days Postoperative Narcotic Use

    To determine if narcotic use changes when patients use lidocaine patches by counting amount and frequency of narcotic use over admission. Average number of 5 mg oxycodone pills used in women who have undergone cesarean delivery assessed through questionnaire at 5 days postoperatively.

    Measured: Postoperative (5 days)

A Phase 4 study testing Lidoderm 5 % Topical Patch in people with Pain, Postoperative, run by Oregon Health and Science University 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 3 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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

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?

12-hour Postoperative Pain Scores (time frame: Postoperative (12 hours)). The study lists 4 primary outcomes in all. 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?
