Trial summary

Traditionally, video-assisted thoracic surgery is performed under general anesthesia with double-lumen endotracheal tube. However, the complications associated with this large tube as well as inhalation anesthetics are frequently reported. Read more about this study

About this study

Official title: Ultrasound-guided Peripheral Nerve Block for Non-intubated Uniportal Video-assisted Thoracoscopic Surgery

Traditionally, video-assisted thoracic surgery is performed under general anesthesia with double-lumen endotracheal tube. However, the complications associated with this large tube as well as inhalation anesthetics are frequently reported. Therefore, currently there is a trend toward non-intubated anesthesia methods for video-assisted thoracic surgery, which includes thoracic epidural block, peripheral nerve block, local anesthesia, local combined with peripheral nerve block, etc. Thoracic epidural block demands a high technique, but still risks catastrophic neurological complications in case of accidental dural puncture. Local anesthesia, perhaps more straightforward, however may need supplemental analgesia during incision, which will inevitably interrupt surgery and negatively affect the patients. This study aims to apply ultrasound guidance during local anesthetic injection for local anesthesia-based video assisted thoracic surgery, which helps inject the local anesthetic into the key intercostal nerve plane to provide more specific and precise blockade, thus avoiding the chance of blind injection. At the same time, ultrasound guidance has the potential to reduce the risk of systemic toxicity, prolong the duration of analgesia postoperatively, and facilitates postoperative recovery.

Being tested
VATS, Ropivacaine, Epinephrine

What participants receive

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

  • VATSProcedure or surgery

    VATS is the abbreviation of video-assisted thoracic surgery, which aims to minimize the wound for thoracic surgery and to enhance patient recovery after surgery

  • RopivacaineDrug

    30 mL 0.5% ropivacaine is used to achieve VATS block

  • EpinephrineDrug

    1:400000 epinephrine is mixed with ropivacaine (local anesthetic) to reduce the risk of local anesthetic systemic toxicity

Study groups in NCT03083080
Study groupRoleWhat they receive
VATS block (ropivacaine + epinephrine)ExperimentalVATS block is the peripheral nerve block for video-assisted thoracic surgery, whose injection is administered at the site of chest wall incision.
Receives: Procedure: VATS; Drug: Ropivacaine; Drug: Epinephrine

What is being measured

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

  1. Numerical rating scale intraoperatively

    Self-reporting pain intensity, pain site, and analgesic dosage during surgery

    Measured: During chest wall incision

  2. TIme to lose skin sensation (light touch and thermal) over the injection site

    Skin sensation will be tested every 5 minutes after ropivacaine injection until loss of both sensation (readiness for skin incision)

    Measured: Up to 30 mins after ropivacaine injection

Secondary outcomes (3)
  1. Ropivacaine concentration at different time points after injection

    Blood sampling at seven time points (10, 20, 30, 45, 60, 90, 120 minutes following injection)

    Measured: Up to 120 mins following injection

  2. Common characteristics of ultrasound anatomy by analyzing video clips

    Recording the ultrasound images at three time points

    Measured: Three time points (upon obtaining informed consent, prior to injection and during injection)

  3. Numerical rating scale postoperatively

    Pain scores evaluated at six time points (at the conclusion of surgery, and at 2h, 6h, 24h, 48h, and 72h post-surgery)

    Measured: Up to 72 hours following surgery

Questions about this trial

What is this clinical trial studying?

A study testing VATS, Ropivacaine and Epinephrine in people with Efficacy and Safety of VATS Block, run by Taipei Medical University WanFang Hospital.

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 1 inclusion and 20 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: status not confirmed, as of the sponsor's last update on 22 Mar 2017. Status can change between updates, so confirm with the study contact before making plans.

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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Jui-An Lin (+886-2-29307930 ext. 2160, juian.lin@tmu.edu.tw), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Numerical rating scale intraoperatively (time frame: During chest wall incision). The study lists 2 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?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Mar 2017.
