About this trial
This prospective observational study aims to evaluate the association between preoperative frailty and the procedural difficulty of ultrasound-guided internal jugular vein catheterization in adult patients undergoing elective cardiac surgery.
Frailty will be assessed using the Clinical Frailty Scale and handgrip strength measurements. Preprocedural ultrasound evaluation will include internal jugular vein anatomical characteristics such as anteroposterior and transverse vein diameters, cross-sectional area (CSA), common carotid artery diameter, skin-to-vein distance, overlap status, and sternocleidomastoid muscle thickness Catheterization difficulty will be assessed using the Gaber Procedural Difficulty Index.
The study seeks to determine whether frailty and ultrasound-derived anatomical parameters can predict difficult internal jugular venous catheterization and improve preprocedural risk assessment without altering routine clinical care.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Adults aged 18 years or older.
Scheduled for elective cardiac surgery.
Planned ultrasound-guided internal jugular vein catheterization as part of routine perioperative care.
Able to undergo preoperative frailty assessment using the Clinical Frailty Scale (CFS).
Disqualifiers
Previous neck surgery.
History of radiotherapy to the neck region.
Presence of a neck mass, infection, or any lesion that may distort neck anatomy.
Known internal jugular vein thrombosis.
Trial population
Adult patients (≥18 years) scheduled for elective cardiac surgery at Ankara Bilkent City Hospital who require ultrasound-guided internal jugular vein catheterization as part of routine perioperative care. Participants will undergo preoperative frailty assessment, handgrip strength measurement, and ultrasound evaluation of the internal jugular vein before catheterization.

Trial outcomes
Primary outcomes
1
Difficult ultrasound-guided internal jugular vein catheterization
Difficult catheterization will be defined as a Gaber Procedural Difficulty Score \>4. The Gaber Procedural Difficulty Score will be calculated at the completion of the ultrasound-guided internal jugular vein catheterization procedure. The score includes four procedural domains: number of puncture attempts, cannulation time, procedure-related complications, and procedural success. Total scores range from 4 to 11 points, with higher scores indicating greater procedural difficulty.

Independent predictive value of ultrasonographically measured anatomical parameters for difficult catheterization
The independent predictive value of ultrasonographically measured anatomical parameters of the internal jugular vein for difficult catheterization will be evaluated. Anatomical parameters will include internal jugular vein anteroposterior diameter, transverse diameter, cross-sectional area, common carotid artery diameter, skin-to-vein distance, overlap status, and sternocleidomastoid muscle thickness. Difficult catheterization will be defined as a Gaber Procedural Difficulty Score \>4. These variables will be evaluated as potential independent predictors of difficult catheterization.
Time frame
Ultrasound assessment after anesthesia induction before catheterization; difficult catheterization status at completion of the catheterization procedure2
Internal jugular vein anteroposterior diameter
The anteroposterior diameter of the internal jugular vein will be measured by ultrasound before catheterization. The value will be reported in millimeters.
Time frame
After anesthesia induction, before catheterization3
Internal jugular vein transverse diameter
The transverse diameter of the internal jugular vein will be measured by ultrasound before catheterization. The value will be reported in millimeters.
Time frame
After anesthesia induction, before catheterization4
Internal jugular vein cross-sectional area
The cross-sectional area of the internal jugular vein will be measured by ultrasound before catheterization. The value will be reported in square millimeters.
