Trial summary

Patients experience pain after surgery mostly from their abdominal wounds, even when those wounds are small. Decreasing that pain has many benefits. It improves comfort, decreases stress response and might improve the outcome of the surgery. Read more about this study

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Who may be able to join

  • Subjects who have benign or malignant colonic or rectal disease that are being scheduled for laparoscopic colorectal resection.
  • Subjects who are 18 years of age and older
  • Subjects of either sex
  • Subjects who are willing and able to adhere to protocol requirements, agree to participate in the study program and provide written and informed consent.

About this study

Official title: Evaluation of a TAP Block as Part of an Enhanced Recovery Pathway in Laparoscopic Colorectal Surgery: A Prospective, Randomized, Double-blinded Multi-institution Trial

Patients experience pain after surgery mostly from their abdominal wounds, even when those wounds are small. Decreasing that pain has many benefits. It improves comfort, decreases stress response and might improve the outcome of the surgery. Local anesthesia (which is a numbing agent given directly at the site of pain via a needle) is given to decrease the pain that is felt after surgery and decrease the need for strong pain medications which can have negative side effects.

One promising way to give local pain medication is called the "transversus abdominis plane" or TAP block. This method works by directly blocking the nerves in the abdomen that are the cause of the pain patients feel in their incision after surgery. This is done by injecting a numbing agent (Bupivacaine) into the area of their abdomen where their nerves are located that cause pain.

In the case of nerves that carry sensation, bupivacaine blocks the pain sensation traveling in a particular nerve.

Patients will be randomized (like a flip of a coin) to receive either a normal saline injection or the bupivacaine injection.

The purpose of this study will be to prove the effectiveness of local anesthetic given via a TAP block in improving postoperative pain, decreasing the use of pain medications, decreasing postoperative nausea and vomiting and improve surgical outcomes such as hospital length of stay in laparoscopic colorectal surgery.

Read the detailed description

Using standard surgical procedures, the surgeon will proceed with the planned laparoscopic surgery. All procedures will be done by straight laparoscopic technique according to standard of care. At the completion of the procedure, and under laparoscopic control, patients will have a TAP block placed by the attending surgeon. The clinical research nurse involved in the research will prep the solution to be injected and the surgeon will be blinded as to whether the patient will be receiving normal saline or Marcaine in the TAP blocks. The block will be administered between the costal margin and iliac crest in the anterior axillary line. A Braun Stimuplex A insulated needle (80 mm 21 gauge) with 0.5 mL/kg solution (max of 30 ml) is passed through the skin, and then continued until two distinct "pops" are felt, which indicates the needle piercing each of the two fascial layers. The needle is then deemed to be in the inter-muscular plane between internal oblique and transversus abdominis muscles respectively, to target the spinal nerves in this plane. The laparoscope will be visualizing for the needle tip to ensure that it does not penetrate the peritoneum or inject pre-peritoneally. The local anesthetic is infiltrated in two separate injections into the same plane on each side. If a sub-peritoneal bleb is seen to be raised by the laparoscope, then the needle will be withdrawn slightly. Two thirds of the solution is injected, and the needle is withdrawn 5 mm and the remaining solution is injected. If injecting in the correct plane, then a smooth raised area of fluid, covered by transversus will be seen via the laparoscope. This procedure is repeated on the patients other side, to complete a bilateral block. Depending on their randomization, patients will receive one of the following solutions:

Group A: Represents the control group and will receive 0.5 ml/kg of 0.9% normal saline for a maximum of 30 ml.

Group B: Represents the experimental group and will receive 0.5 ml/kg of 0.25% Marcaine (bupivacaine) for a maximum of 30 ml.

What is being measured

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

  1. Postoperative Pain as Measured by Pain Score

    Pain measured via score of 1 to 5, with 1 being no pain and 5 being the worst pain

    Measured: up to 10 days

Secondary outcomes (1)
  1. Percent of Analgesics Used as Measured by Patient Report

    Measured: Up to 30 days after surgery

Questions about this trial

What is this clinical trial studying?

A study testing bupivacaine in people with Colorectal Disease, run by University Hospitals Cleveland Medical 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 4 inclusion and 4 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 3 Nov 2022. 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. 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.

Are results available for this study?

Yes. Results are posted in the registry (first posted 3 Nov 2022). 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 as Measured by Pain Score (time frame: up to 10 days). 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 3 Nov 2022.
