Central Venous Catheter Insertion Techniques

anatomical landmarks (sternocleidomastoid muscles, sternal notch, cricoid cartilage, carotid artery and clavicle) will be palpated. A 3cc syringe with 21 gauge needle (locator) will be used first to locate IJV at the apex of the triangle formed by the two heads of the sternocleidomastoid muscle. After successful location, an introducer needle of 18 gauge, attached with a 5 ml syringe, will be inserted at the same point. The introducer needle will be directed towards the ipsilateral nipple at an angle of 20-30° with the skin

In Group Ultrasound-guided pre location technique, venipuncture site will be determined using ultrasound probe which will be then removed and locator needle of 21 gauge will be used first to confirm IJV location. The cannulation or venipuncture will be performed at the marked point of locator needle by the use of 18 gauge introducer needle.

In Group Ultrasound-guided real-time technique, cannulation or venipuncture will be performed under real-time imaging using 18 gauge needle i-e ultrasound will be used for prelocation and puncturing of IJV and locator needle will not be used
