About this study

Official title: Different Local Anesthetic Volumes for Unilateral Spinal Anesthesia in Varicose Vein Surgery

Varicose veins are irreversible and abnormal enlargement of the veins. These veins appear and there are curled swellings under the skin in the feet and legs. Complaints increase when standing and sitting for long periods. For varicose veins in the initial stages, medical treatment methods such as compression socks (elastic socks) and elevating the feet as much as possible can be tried. For widespread varicose veins in more advanced stages, invasive procedures such as sclerotherapy and endovascular ablation are performed. These procedures can be performed under local, spinal or general anesthesia.

Spinal anesthesia; It is a type of neuraxial type of regional anesthesia characterized by injecting local anesthetic drugs into the subarachnoid space alone or together with other drugs, resulting in temporary sensory block, motor block, and sympathetic block. The local anesthetic volume administered during spinal anesthesia may affect the anesthesia levels and discharge times of the patients. For varicose vein surgeries, low-dose local anesthetic is sufficient for spinal anesthesia and can also provide early discharge.

This study will compare the peri-operative effects of different doses of spinal anesthesia in patients undergoing varicose vein surgery.

What participants receive

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

  • 4 mg bupivacaineProcedure or surgery

    Spinal anesthesia was applied to the patients with 4 mg bupivacaine in the lateral decubitus position.

  • 6 mg bupivacaineProcedure or surgery

    Spinal anesthesia was applied to the patients with 6 mg bupivacaine in the lateral decubitus position.

What is being measured

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

  1. Discharge time

    The time (minutes) from the application of spinal anesthesia to the patients' discharge will be recorded as the discharge period.

    Measured: On the operation day

Secondary outcomes (4)
  1. Motor block appearing time

    Time (minutes) to complete motor block in the lower extremity after spinal anesthesia

    Measured: On the operation day

  2. Sensorial block appearing time

    Time (minutes) to complete sensorial block in the lower extremity after spinal anesthesia

    Measured: On the operation day

  3. Motor block disappearing time

    Time (minutes) to disappearance of complete motor block in the lower extremity after spinal anesthesia

    Measured: On the operation day

  4. Sensorial block disappearing time

    Time (minutes) to disappearance of sensorial block in the lower extremity after spinal anesthesia

    Measured: On the operation day

Questions about this trial

What is this clinical trial studying?

A study testing 4 mg bupivacaine and 6 mg bupivacaine in people with Discharge Time and Ambulatory Surgery, run by Ankara Etlik City Hospital at 1 site in Turkey (Türkiye).

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 4 Jun 2025. 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 Turkey (Türkiye). 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?

Discharge time (time frame: On the operation 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 NCT06527430, which also lists 1 linked publication.

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 4 Jun 2025.
