Abstract     Introduction: Catheterization of central venous vessels allows access for hemodynamic monitoring, administration of drugs, fluids and parenteral nutrition, placement of a difficult peripheral IV cannula and hemodialysis. Aims and Objectives: To study comparison of classical blind anatomical landmark technique of subclavian venous cannulation with ultrasound guided technique with respect to Access time and Success rate. Methodology: Prospective randomised comparative study conducted in the Department of Anaesthesiology and Intensive Care at Government Medical College Hospital, Jammu w.e.f. February 2015 to June 2015. Patients admitted in Government Medical College Hospital, Jammu who required subclavian vein cannulation were the subject of the study. 60 patients .Group-I (anatomical landmark technique) Group-II (ultrasound-guided technique) Patients subclavian vein was cannulated under strict aseptic precaution via infraclavicular approach. The Statistical analysis done by Unpaired t-test and Chi-square test calculated by SPSS (SPSS Inc, Chicago) software packages. Result: The Average Access time was more i.e. 5.368333 ±2.096528 in LMG group as compared to USG group where it was 2.365 ± 1.079843 this observed difference is statistically significant (t= 6.975; p<0.001) With USG technique more veins were entered on the first attempt. In our study, in USG technique all the 30 (100%) patients were cannulated on first attempt versus 23 (76.66%) patients in LMG technique was cannulated on the first attempt this observed difference is statistically significant (Fisher's exact test – P< 0.0105). Conclusion: USG guided SCV cannulation can be practised in future as the access time and success rate are better than the LMG group.

Keywords: LMG Technique, USG guided SCV cannulation.
