Comparative Evaluation of Ultrasound Guided Supraclavicular and Infraclavicular Subclavian Venous Catheterizations in Adult Patients Undergoing Major Surgeries

ultrasound is a medical device which is frequently used for safe venous punctures as you can visualise the structures.so, device ''ultrasound'' will be used for intervention ''central line insertion'' in subclavian vein. ultrasound guided cannulation of the subclavian vein was done by supraclavicular or infraclavicular approach after randomization into either of the two groups.In the supraclavicular approach the puncture site is above the clavicle while in the infraclavicular group the puncture site is below the clavicle. Central venous cannulation is done after identifying the vein on ultrasound and using standard seldinger technique with full asepsis.
