About this study

Official title: Extended Release Local Anesthetic for Postsurgical Pain After Posterior Colporrhaphy and Perineorrhaphy: A Randomized Controlled Study

The specific aim of this randomized double-blind clinical trial is to evaluate the effect of intraoperative infiltration of liposomal bupivacaine at the time of posterior colporrhaphy and/or perineorrhaphy on postsurgical pain scores during the first 72 hours after surgery as measured by visual analog scales (VAS) for patients undergoing surgery for pelvic organ prolapse. Study subjects are randomized to 30 mL of liposomal bupivacaine versus 30 mL of injectable normal saline administered in a standardized technique into the posterior vaginal compartment at the time of posterior repair and/or perineorrhaphy.

Read the detailed description

Liposomal bupivacaine (EXPAREL; Pacira Pharmaceuticals, San Diego, CA) is an extended release local anesthetic approved by the Food and Drug Administration since 2011 for the treatment of postsurgical pain. It is a multivesicular liposomal delivery system, consisting of a liquid bupivacaine core encapsulated by a phospholipid shell. This delivery technology allows for the slow, sustained release of bupivacaine over at least 72 hours.

Liposomal bupivacaine has been studied extensively in the general surgery and orthopedic surgery literature. Specifically, infiltration of liposomal bupivacaine after excisional hemorrhoidectomy has been shown to significantly lower postsurgical pain scores, decrease total postoperative opioid requirements, increase the number of patients who do not require any opioids after surgery, meaningfully delay the median time to first opioid use, and improve patient satisfaction with overall perioperative analgesia.

Posterior colporrhaphy and perineorrhaphy are pelvic reconstructive surgical procedures that are associated with significant postsurgical localized pain resulting from surgical incisions. Investigators hypothesize this localized postsurgical pain will benefit from treatment with an extended release local anesthetic formulation similar to hemorrhoidectomy. Intraoperative infiltration of a standard local anesthetic during posterior repair and perineorrhaphy has been shown to improve early analgesia and facilitate early postoperative recovery. These findings reiterate the need for studies investigating a slow-release, longer-acting local anesthetic formulation for patients undergoing posterior repair and/or perineorrhaphy - one that ideally can be integrated into an evidence-based, opioid-sparing postsurgical pain management regimen to improve perioperative care for the steadily growing pelvic reconstructive surgical patient population.

The primary study objective is to evaluate the effect of intraoperative infiltration of liposomal bupivacaine at the time of posterior colporrhaphy and/or perineorrhaphy on postsurgical pain scores during the first 72 hours after surgery as measured by visual analog scales (VAS).

Secondary objectives include to evaluate total opioid consumption during the first 72 postoperative hours, to evaluate patient satisfaction with postoperative analgesia, to evaluate time to first opioid administration postoperatively, to evaluate hospital length of stay, to evaluate length of stay in post-anesthesia care unit (PACU), to evaluate total hospital costs, to evaluate time to first bowel movement postoperatively, to evaluate rate of postoperative nausea and vomiting, to evaluate time to successful voiding trial, and to evaluate proportion of patients discharged home with a Foley catheter.

Patients will be approached for participation preoperatively and randomized in the operating room to either liposomal bupivacaine or injectable normal saline administered into the posterior vaginal compartment in a standardized technique. All concurrent minimally invasive pelvic reconstructive surgical procedures are allowed. Randomization will be stratified for abdominal versus purely vaginal surgery. Perioperative care is standardized. Data will be abstracted from the medical record. Additionally, subjects will be discharged home with a medication diary and pain scales. Subjects will record their pain every morning and every evening for the first 72 hours after surgery. Subjects will complete a satisfaction survey at their 2 week postoperative visit. Adverse postoperative outcomes will be collected for 30 days after surgery.

The study is powered to detect a 20 mm difference in a 100 mm visual analog scale for pain.

What is being measured

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

  1. Postoperative Pain

    As measured by a 100 mm Visual Analog Scale (VAS). This scale ranges from 0-100 mm with 0 mm indicating no pain and 100 mm indicating the most pain. The study is powered to detect a decrease in postoperative pain by 20 mm on this scale, which is considered to be a clinically meaningful difference in prior studies. Results will be reported as mean pain scores at each time point (night of surgery, morning and evening for the first 72 hours after surgery, i.e. until postoperative day#3).

    Measured: Night of surgery (POD#0), POD#1 morning, POD#1 evening, POD#2 morning, POD#2 evening, POD#3 morning, POD#3 evening

Secondary outcomes (9)
  1. Number of Participants Reporting Satisfaction With Pain Control

    As measured by a 5-question satisfaction survey administered at a 2 week postoperative visit. The survey includes Likert scale responses ranging from very unsatisfied to very satisfied with the surgical experience and specifically analgesia. "Patient Satisfaction" was defined as response "satisfied" or "very satisfied" on the Likert Scale. Average responses will be reported.

    Measured: 2 weeks after surgery

  2. Time to First Opioid Administration

    Median time until first opioid administered after surgery

    Measured: Assessed up to 72 hours after surgery

  3. Total Opioid Administration

    Measured in milligram morphine equivalents

    Measured: Cumulatively, over a time period of 72 hours after surgery

  4. Number of Antiemetic Doses Required Per Participant While Inpatient

    Number of as-needed antiemetic doses patient received while in the hospital after surgery

    Measured: Cumulatively, over a time period of 72 hours after surgery

  5. Hospital Length of Stay

    Total length of hospital stay measured in hours, including readmissions

    Measured: Assessed until 30 days after surgery

  6. Length of Stay in Post-anesthesia Care Unit (PACU)

    Total length of stay in PACU measured in minutes

    Measured: Assessed up to 72 hours after surgery

  7. Number of Participants Who Had a Bowel Movement Within the First 3 Postoperative Days

    As recorded by patient - patients were asked each postoperative day (i.e. POD#0, POD#1, POD#2, POD#3) if they had a bowel movement that day, yes or no.

    Measured: 72 hours after surgery

  8. Voiding Trial Failures

    Proportion of patients discharged home with Foley catheters after failed voiding trials in the hospital

    Measured: 2 weeks after surgery

  9. Number of Patients With Adverse Events

    Total adverse postoperative events

    Measured: Assessed until 30 days after surgery

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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 13 May 2020). 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?

Postoperative Pain (time frame: Night of surgery (POD#0), POD#1 morning, POD#1 evening, POD#2 morning, POD#2 evening, POD#3 morning, POD#3 evening). 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?
