Facilitating Needle Alignment With Aiming Method

Not Applicable

Completed

• Conditions: Central Venous Catheters
• Interventions: Procedure: Ultrasound-guided plus needle guide techniques; Procedure: subclavian vein catheterization; Procedure: landmark techniques

• Registration Number: NCT03778437
• Lead Sponsor: Daping Hospital and the Research Institute of Surgery of the Third Military Medical University

Brief Summary

Although ultrasound-guided catheterization of the subclavian vein is becoming standard procedure in anesthetic practice, failure to align the needle and the transducer still can lead to possibly complications. In this study, we proposed a new alignment method, namely Aiming Method. The purpose of this study is to investigate whether the use of this aiming method improved resident volunteers' performance of ultrasound-guided SC insertion in real patients. Specifically, residents were asked to perform three different methods: landmark techniques, ultrasound-guided with aiming method and ultrasound-guided plus needle guide techniques.

Arm && Interventions

Group	Intervention	Description
ultrasound-guided plus needle guide techniques	Ultrasound-guided plus needle guide techniques	Subclavian vein catheterization is performed under ultrasound guidance with in-plane technique.
ultrasound-guided with aiming method	subclavian vein catheterization	Subclavian vein catheterization is performed with our newly proposed aiming method with the guidance of ultrasound.
landmark techniques	landmark techniques	Subclavian vein catheterization is performed without the guidance of ultrasound. The needle was inserted 1 cm inferior and 1 cm lateral to the junction of the middle and medial thirds of the clavicle (infraclavicular approach)

Primary Outcome Measures

Name	Time	Method
Procedural time	24 hours	the time from skin break to guide wire was positioned into the subclavian vein
Number of skin breaks	24 hours	number of skin punctures

Secondary Outcome Measures

Name	Time	Method
The incidence of arterial puncture	24 hours	aspiration of arterial blood during needle insertion or local haematoma in ultrasound image
The incidence of pneumothorax	24 hours	aspiration of air during needle insertion, or thoracic ultrasonography, or chest radiography
