About this study
Official title: Comparing Axillary Vein Cannulation with 'Hockey' Probe Versus Linear Probe for Central Venous Access
Central venous catheterization, specifically through the axillary vein, is a procedure of critical importance in various clinical contexts. Site selection is dependent on clinical assessment, experience and the physician preference. This study aims to evaluate the potential advantages of using the "hockey stick" ultrasonography probe for axillary vein cannulation and determine whether this probe enhances axillary vein imaging, accelerates the central vein cannulation procedure and reduces the rate of complications compared to the linear probe. Methods: 100 participants were recruited and allocated into two groups: the linear probe group and the hockey stick probe group. All procedures were performed by two senior anesthesia and intensive care residents, each with experience of over 100 central vascular access procedures. Follow-up chest X-rays were taken two hours post-procedure to verify the correct position of the catheter and to rule out complications such as pneumothorax, hemothorax, cardiac tamponade, and incorrect line placement.

What is being measured
The primary outcome is the main question the study is designed to answer.
Success on first attempt
An attempt is defined by every needle direction change. Whenever vein puncture was not achieved by a simple, straight movement without any change of direction in any plane this cannulation was not counted as success at first attempt
Measured: 24 hours
Number attempts
An attempt is defined by every needle direction change. Whenever vein puncture was not achieved by a simple, straight movement without any change of direction in any plane this cannulation was not counted as success at first attempt
Measured: 24 hours
Procedure Time
The procedure time measurement stops when skin dressing is applied. Time measurement was done by an independent observer.
Measured: 24 hours
Cumulative number of complications
Complications early and late were recorded either with ultrasonography immedi-ately after the procedure or in the chest X-ray 2 hours after.
Measured: 24 hours
