Introduction. Central venous catheterization of the subclavian vein can be achieved with a landmark and an ultrasound-guided method. Using ultrasound the vein can be catheterized with a long axis in plane or a short axis out of plane approach and a combined approach. The aim of the study was to compare the success, average number of attempts and mechanical compli- cation rate between the landmark and the combined ultrasound-guided method. Methods. A total of 162 adult patients from the Intensive Care Unit at Clinical Hospital Acibadem-Sistina, Skopje were included in this prospective study. Patients rando- mized in the examined group (n=71) were catheterized with real-time ultrasound guidance with a combined short axis out of plane and long axis in plane method. Patients randomized in the control group (n=91) were catheterized with the landmark method. Subclavian vein was catheterized in both groups. Overall success, success on first attempt, number of attempts and complications at the moment of catheterization were the main outcome measures. Results. Catheterization using the landmark method was successful in 94.5% of patients, 65.9% of which during the first attempt. Cannulation using real-time ultrasound guidance was successful in all patients with a first pas success of 83.1%. Conclusion. Real-time ultrasound guidance with a combined short axis out of plane and long axis in plane approach improves success, decreases number of attempts, and reduces mechanical complications rate.

introduction: Central venous catheterization is performed by the landmark method and ultrasound guided meth- od. The purpose of the study was to compare the success, average number of attempts, average time to return of blood, and complication rate between the two methods. Material and Methods: This was a prospective study done in the Intensive Care Unit of the Acibadem Sistina Clinical Hospital, in Skopje. There were 400 patients in need of central venous catheter and they were prospectively randomized in two groups. The patients randomized in the examined-ultrasound group underwent real-time ultrasound-guided catheterization and the patients randomized in the control-landmark group were catheterized using the landmark method. Internal Jugular, Subclavian and Femoral vein were catheterized in both groups. The Overall success, success on the first attempt, time to the return of blood, number of attempts and complications at the moment of catheterization such as arterial puncture, pneumothorax and hematoma formation were the main outcome measures. results: The catheterization using the landmark method was successful in 90.5% of patients, 60.5% of which during the first attempt. The cannulation using real-time ultrasound guidance was success- ful in 98% of patients with a first pass success of 77%. The complication rate with the landmark method was 14.5% versus 4% with real-time ultrasound guidance p<0.05(p=0.0008). conclusion: Real-time ultrasound guidance improves success, decreases number of attempts, decreases average time to the return of blood and reduces mechanical complications rate
