Study summary

Internal jugular vein (IJV) catheterization is a common invasive procedure performed under ultrasound (USG) guidance. Providing effective analgesia during the procedure is essential for patient comfort. This prospective, randomized controlled study aims to compare the clinical efficacy, onset time, required local anesthetic volume, and hemodynamic stability between ultrasound-guided local infiltration anesthesia (LIA) and ultrasound-guided superficial cervical plexus block (SCPB) using different volumes (2 mL, 5 mL, and 10 mL of 1% lidocaine) in patients undergoing IJV catheterization.

Read the detailed description

Central venous catheterization (CVC) is a widely used invasive procedure in critically ill and high-risk surgical patients for fluid resuscitation, hemodynamic monitoring, continuous infusion of vasoactive or venosclerotic drugs, and hemodialysis/hemofiltration. Among available vascular access sites, internal jugular vein (IJV) cannulation is the most commonly preferred route. However, awake patients undergoing IJV catheterization often experience significant pain and distress, which may negatively impact hemodynamic stability, patient comfort, and procedural success.

Although local infiltration anesthesia (LIA) is traditionally used to provide analgesia during IJV catheterization, it frequently falls short of providing optimal pain control. Ultrasound-guided regional anesthesia techniques, such as superficial cervical plexus block (SCPB), have emerged as effective alternatives for procedures involving the anterolateral neck region.

While both LIA and SCPB are utilized in clinical practice, there is a lack of prospective randomized literature directly comparing different local anesthetic volumes, onset times, and overall clinical efficacy between these two approaches. This prospective, randomized controlled trial aims to evaluate and compare ultrasound-guided LIA and SCPB in terms of anesthetic efficacy, onset time, required local anesthetic volume, and hemodynamic stability in patients undergoing IJV catheterization.

Inclusion criteria

Patients aged between 18 and 80 years

Glasgow Coma Scale (GCS) score between 13 and 15

Patients scheduled for elective or semi-elective ultrasound-guided internal jugular vein catheterization

Patients who are literate, capable of effective communication, and provide written

Exclusion criteria

Exclusion Criteria:

  • Glasgow Coma Scale (GCS) score \< 13

Age \< 18 years or > 80 years

IV or higher

Internal jugular vein catheterization performed under general anesthesia

Internal jugular vein catheterization performed under emergency conditions

Distorted head and neck anatomy preventing adequate ultrasound visualization for the block

Arterial puncture on the first needle insertion attempt

Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

ASA physical status

The anaesthetists’ scale of health before surgery: I is healthy, II has a mild illness that is under control, III a severe one, IV a severe illness that is a constant threat to life. V and VI are used for the critically ill and for organ donors.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Study arms

  • Active comparator
    Local Infiltration Anesthesia (LIA Group)

    10 mL of 1% lidocaine hydrochloride is injected subcutaneously over the sternocleidomastoid muscle at the C6 level for local infiltration prior to internal jugular vein catheterization (n=75).

    Drug: Lidocaine HCl 1%

  • Experimental
    Superficial Cervical Plexus Block - 2 mL (SCPB 2 mL)

    Ultrasound-guided superficial cervical plexus block administered beneath the sternocleidomastoid muscle at the C6 level using 2 mL of 1% lidocaine hydrochloride (n=25).

    Drug: Lidocaine HCl 1%

  • Experimental
    Superficial Cervical Plexus Block - 5 mL (SCPB 5 mL)

    Ultrasound-guided superficial cervical plexus block administered beneath the sternocleidomastoid muscle at the C6 level using 5 mL of 1% lidocaine hydrochloride (n=25).

    Drug: Lidocaine HCl 1%

  • Experimental
    Superficial Cervical Plexus Block - 10 mL (SCPB 10 mL)

    Ultrasound-guided superficial cervical plexus block administered beneath the sternocleidomastoid muscle at the C6 level using 10 mL of 1% lidocaine hydrochloride (n=25).

    Drug: Lidocaine HCl 1%

Interventions

  • Administration of 1% lidocaine hydrochloride either via ultrasound-guided superficial cervical plexus block (at 2 mL, 5 mL, or 10 mL volumes) or via subcutaneous local infiltration (10 mL) prior to internal jugular vein catheterization.

What researchers measure

Primary outcomes

  1. Time to Effective Block Onset Across Different Local Anesthetic Volumes

    Time elapsed (in seconds) from injection completion until effective analgesia is achieved (defined as an NRS score ≤ 2 via pin-prick test every 5 seconds), evaluating whether lower volumes of SCPB (2 mL and 5 mL) achieve effective block onset in a comparable timeframe to higher volume SCPB (10 mL) and standard LIA (10 mL).

    Time frame: Evaluated every 5 seconds, up to 5 minutes post-injection.

  2. Time to Effective Block Onset Across Different Local Anesthetic Volumes

    Time elapsed (in seconds) from injection completion until effective analgesia is achieved (defined as an NRS score ≤ 2 via pin-prick test every 5 seconds), evaluating whether lower volumes of SCPB (2 mL and 5 mL) achieve effective block onset in a comparable timeframe to higher volume SCPB (10 mL) and standard LIA (10 mL).

    Time frame: Evaluated every 5 seconds, up to 5 minutes post-injection

Secondary outcomes

  1. Pain Intensity Across Procedural Stages (NRS Scores)

    Evaluation of pain intensity using the Numerical Rating Scale (NRS, 0 = no pain to 10 = worst pain) to compare whether low-volume SCPB provides comparable pain control to high-volume SCPB and LIA across different procedural steps.

    Time frame: At baseline, during infiltration/block injection, during initial needle insertion, and during catheter placement.
