  • Ages 18 to 75 years
  • All sexes
  • Healthy volunteers accepted
  • Adult, Older adult

Study population: Adult and elderly patients (18-75 years) undergoing elective or scheduled surgery in the general operating room unit of Dicle University Faculty of Medicine Hospital who require central venous catheterization via the internal jugular vein as part of routine perioperative care. The catheterization technique (ultrasound-guided or landmark) reflects the routine practice of the performing physician; no technique is assigned by the study for research purposes.

  • Patients aged 18-75 undergoing surgery requiring central venous (internal jugular) catheterization

Who cannot join

  • Refusal to participate
  • age <18 or >75
  • emergency surgery
  • coagulopathy
  • infection, prior surgery, or prior cannulation at the insertion site
  • allergy to ultrasound gel

About this study

Official title: The Effect of Ultrasound Guidance Versus Landmark Technique on Catheter Malposition in Internal Jugular Vein Catheterization

Central venous catheterization (CVC) via the internal jugular vein (IJV) is a fundamental procedure in anesthesia and intensive care for hemodynamic monitoring, fluid resuscitation, and vasoactive drug administration. While modern clinical guidelines strongly advocate for ultrasound (USG) guidance, the traditional anatomical landmark technique remains widely utilized due to equipment availability or clinician habits. Proper positioning of the catheter tip is critical to prevent severe long-term complications; however, comparative data regarding catheter tip malposition between these two routine techniques-especially when confirmed by postprocedural bedside chest X-ray-require further prospective evaluation. Objective:

The primary objective of this prospective observational study is to compare ultrasound-guided versus landmark techniques for internal jugular vein catheterization with respect to catheter tip malposition, as determined by postprocedural bedside chest X-ray. Secondary objectives include the evaluation of the number of needle redirections, first-attempt success rate, total procedure time, and the incidence of mechanical complications (such as accidental arterial puncture or hematoma formation)

Being tested
Ultrasound-Guided Technique, Landmark Technique

What participants receive

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

  • Ultrasound-Guided TechniqueProcedure or surgery

    Internal jugular vein catheterization performed with real-time ultrasound visualization of the vein to guide needle insertion.

  • Landmark TechniqueProcedure or surgery

    Internal jugular vein catheterization performed using external anatomical landmarks without real-time ultrasound guidance.

What is being measured

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

  1. Incidence of catheter tip malposition

    Measured: Assessed on postoperative bedside chest X-ray, immediately following the procedure

Secondary outcomes (1)
  1. Incidence of Procedural Mechanical Complications

    The occurrence and rate of immediate mechanical complications directly related to the intervention, specifically tracking accidental carotid arterial punctures and hematoma formations.

    Measured: During the procedure and up to 24 hours post-operatively.

Questions about this trial

What is this clinical trial studying?

An observational study of Catheter Malposition and Central Venous Catheterization, run by Saglik Bilimleri Universitesi Gazi Yasargil Training and Research 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 1 inclusion and 6 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: enrolling by invitation, as of the sponsor's last update on 2 Sep 2026. 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?

This study is still under way. Results are not available in the source record yet.

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?

Incidence of catheter tip malposition (time frame: Assessed on postoperative bedside chest X-ray, immediately following the procedure). 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 NCT07701720, 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 2 Sep 2026.
