About this study

Official title: Ultrasound Guided Analgesic Caudal Block in Anal Canal Surgery

Interventional study that evaluate analgesia and side effects of Ultrasound guided Caudal block preoperatively in benign canal anal surgery

Read the detailed description

Postoperative pain is an important symptom in patients after benign anal canal surgery. Caudal block has been described to decrease postoperative pain in this type of surgery. Ultrasound is a tool that facilitates its performance and increases the rate of a successful block.

Objective:

To determine the usefulness of ultrasound guided caudal block in anesthesia and postoperative analgesia in patients scheduled for benign anal surgery. Methods : Interventional study in adult patients that received ultrasound caudal anesthetic block before benign anal surgery. The investigators evaluated analgesic efficacy of this intervention by mean of numeric rating scale ( NRS) for pain after 6, 12 and 24 hours of surgery, rescue analgesia, motor block, urinary retention, surgical conditions and patient satisfaction in postoperative period.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Ultrasound Guided Caudal BlockProcedure or surgery

    Using an external ultrasound probe, the investigators guided a 18 gauge epidural needle into the caudal space and injected a local anesthetic solution consisting in bupivacaine 0.25%, lidocaine 1% and dexamethasone 8mg in the caudal space.

Ultrasound Guided Caudal BlockExperimental30 minutes before benign canal anal surgery, a 18 G tuohy needle guided with an ultrasound probe to visualize the caudal space, a solution of bupivacaine 0.25%, Lidocaine 1% and dexamethasone 8mg was injected and needle removed.

What is being measured

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

  1. postoperative pain intensity (P3). Self reported pain intensity at 6, 12 and 24 hours after surgery.

    The pain numeric Rating Scale (NRS) is a single 11-point numeric scale in which a respondent selects a whole number (0-10 integers) that best reflects the intensity of their pain , with 0 representing one pain extreme (e.g., "no pain") and 10 representing the other pain extreme (e.g., "pain as bad as you can imagine" and "worst pain imaginable")

    Measured: 1 day

Secondary outcomes (1)
  1. Rescue Analgesia (R3) need of opioid medication for rescue severe postoperative pain at 6, 12 and 24 hours after surgery.

    Doses of intravenous tramadol for rescue in severe postoperative pain

    Measured: 1 day

Questions about this trial

What is this clinical trial studying?

A study testing Ultrasound Guided Caudal Block in people with Anal Fissure and Anal Fistula, run by Universidad de Antioquia at 1 site in Colombia.

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 30 Apr 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 Colombia. 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?

postoperative pain intensity (P3). Self reported pain intensity at 6, 12 and 24 hours after surgery. (time frame: 1 day). 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 NCT03345511, which also lists 3 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?
