About this study

Official title: Double Blind Randomized Phase III Controlled Trial Comparing the Effect of Intraperitoneal Nebulization of Ropivacaine With Intraperitoneal Instillation of Ropivacaine on Pain Control After Laparoscopic Cholecystectomy

Studies evaluating intraperitoneal local anesthetic instillation for pain relief after laparoscopic procedures have provided conflicting results. This randomized, double-blind study was designed to assess the effects of a novel intraperitoneal local anesthetic administration technique using nebulization on pain relief after laparoscopic cholecystectomy.

Read the detailed description

Studies evaluating intraperitoneal local anesthetic (LA) instillation for pain relief after laparoscopic cholecystectomy have provided conflicting results. One of the factors that might contribute to failure of the instillation technique may be related to inadequate distribution of local anesthetic throughout the peritoneal surface. In contrast, nebulization should provide a uniform spread of drugs throughout the peritoneal cavity and thus may be beneficial to improve pain relief after laparoscopic procedures. A recent study reported that bupivacaine nebulization significantly reduced pain after laparoscopic cholecystectomy compared with bupivacaine instillation in the gallbladder bed. However, these investigators used a custom-made nebulization system that needs a separate gas source and tubing that is cumbersome and may not be easily available.

Recently, the investigators reported that a microvibration-based nebulization device (Aeroneb Pro® system, Aerogen, Galway, Ireland) could be used for ropivacaine delivery into the insufflation gas required to create pneumorpeitoneum. The investigators hypothesized that intraperitoneal ropivacaine nebulization would provide superior pain relief after laparoscopic cholecystectomy than intraperitoneal ropivacaine instillation. This randomized, double blind, controlled clinical trial was designed to assess the analgesic efficacy of ropivacaine nebulization using the Aeroneb Pro® device laparoscopic cholecystectomy compared with intraperitoneal ropivacaine instillation.

What participants receive

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

  • Ropivacaine 60 mgDrug

    Nebulization grou received intraperitoneal instillation of saline 20 ml on the gall bladder after induction of pneumoperitoneum but before dissection of gall bladder plus intraperitoneal nebulization of ropivacaine 1% 3 ml (30 mg) the start of gall bladder dissection and again at the end of surgery just before deflation of pneumoperitoneum (total of 60 mg). The first ropivacaine nebulization was performed over 5-6 minutes using the Aeroneb Pro® device through the umbilical port while the other ports were being inserted, while second nebulization was performed before the withdrawal of the ports

  • Ropivacaine 100 mgDrug

    Instillation group received intraperitoneal instillation of ropivacaine 0.5%, 20 ml (100 mg) on the gall bladder after induction of pneumoperitoneum but before dissection of gall bladder plus and intraperitoneal nebulization of normal saline 3 ml before the start of gall bladder dissection and again at the end of surgery just before deflation of pneumoperitoneum. The first saline nebulization was performed over 5-6 minutes using the Aeroneb Pro® device through the umbilical port while the other ports were being inserted, while second nebulization was performed before the withdrawal of the ports

What is being measured

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

  1. Postoperative Pain

    Postoperative pain was assessed by Visual analgue scale (VAS 0 to 100 points) at rest (static VAS) and after a deep inspiration or cough (dynamic VAS). The proportion of patients with adequate pain control after surgery (dynamic VAS < 3) will also be assessed.

    Measured: 48 hours

Secondary outcomes (4)
  1. Morphine consumption (mg)

    The total dose of morphine at every evaluation after awakening will be quantified using the PACU clinical chart and/or PCA infusers memory display

    Measured: Up to 48 hours

  2. Time of unassisted walking

    Unassisted walking time is defined as the time in hours between PACU discharge and when the patient is able to walk out of his room and back to bed without any assistance.

    Measured: Up to 48 hours

  3. Hospital morbidity

    All complications or adverse effects associated or possibly associated with the interventions under study, surgery or anesthesia will be quantified using the anesthesia charts, surgical charts, surgical database.

    Measured: Up to 48 hours

  4. Time to hospital discharge

    We define hospital stay as the elapsed time between surgery and hospital discharge

    Measured: 48 hours

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 6 inclusion and 10 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 25 Nov 2010. 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 Italy. 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?

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 (time frame: 48 hours). 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 NCT01248819, 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?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Nov 2010.
