Compare Central Line Insertion of Subclavian Vein With Two Different Approaches Using Ultrasound
Conditions
Brief summary
Comparison of two techniques of central venous cannulation of subclavian vein using ultrasound was performed. ultrasound guided central venous cannulation is the standard practice today but its use in subclavian vein is technically challenging and not much literature is available. In this study 96 Patients were randomized into one of the groups and compared for various outcomes. The primary outcome studied was the time taken for procedure. Secondary objectives included comparison of total access time using both the techniques,comparison of first attempt success rate, comparison of the quality of needle visualization and the comparison of immediate (mechanical) and delayed complication rates.
Interventions
PROCEDUREultrasound guided central venous cannulation
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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| puncture time of subclavian vein using ultrasound-guided supraclavicular or infraclavicular approach infraclavicular approaches in adults | 1 year | will be measured in seconds |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| total time taken for cannulation of veins using both the techniques. | 1 year | measured in seconds |
| first attempt success rate | 1 year | number of attempts taken will be measured |
| quality of needle visualisation | 1 year | subjective visualisation of the needle on ultrasound will be noted as good or poor |
| immediate and delayed complications with the two approaches | 1 year | — |
