Objectives: In many patients, especially in severely ill patients using a central vein such as internal jugular vein is necessary for hemodynamic monitoring, receiving intravascular fluids, blood, blood products and medications, total parenteral nutrition, hemodialysis or in patients with difficult or impossible peripheral intravenous cannulation. Accuracy in performing cannulation in minimum time and with the least amount of side effects has particular importance. The aim of the present study is to compare ultrasonic method with anatomical criteria for internal jugular vein catheter insertion in adults requiring cannulation.
Design: Block randomization, without placebo, single center, trial phase 2, including 90 patients under internal jugular vein cannulation.
Setting and conduct: By using a two-cc syringe with needle size equal to 22 and angle of 45-degree, we direct in the groove between the sternocleidomastoid muscles toward the nipple.
Participants including major eligibility criteria: All patients who are supposed to undergo internal jugular vein cannulation.
Intervention: By using an ultrasound probe and by a two-cc syringe with needle size equal to 22 and angle of 45-degree directs in the groove between the sternocleidomastoid muscle toward the nipple.
By using of clinical criteria such as sternal notch, clavicle, and sternocleidomastoid muscle, a two-cc syringe with needle size 22 and 45 degree angle directs in the groove between the sternocleidomastoid muscle toward the nipple.
Main outcome measures: The duration of cannulation, success rate, number of attempts to cannulate a patient.
