Abstract:Subclavian venous catheterization via the supraclavicular approach is an excellent method of central venous access in mechanically ventilated patients. The procedure success rate and the significant complication rate are comparable to other techniques of central venous catheterization.
“…This method can be used successfully and relatively safely by inexperienced as well as experienced physician as a primary or alternative technique when other catheterization sites are not available. 6 Success of cannulation in our study revealed, in Group S 95%, where as in Group I was 92.5% which was statistically not significant with p value of >0.05. This was consistent with study done by Durrani et al 4 where the overall success rate was 96.4% in supraclavicular group and 91.1% in infraclavicular group.…”
Introduction:The subclavian vein access has been the standard recommended approach for central venous catheterization both for short and long-term use. Aim is to compare the supraclavicular and infraclavicular approaches for subclavian venous cannulation in regard to success, attempts required, time taken and complications. Material and Methods: All patients satisfying the inclusion criteria were placed either in group supraclavicular (S) or group infraclavicular (I) approach for right subclavian vein and 7FrG cannula was cannulated using modified Seldinger technique under general anaesthesia. Results: Time taken for successful cannulation in Group (S) were 188.96 + 37.19 seconds and in Group (I) were 299.76 + 69.712 seconds which was statistically significant with p value of <0.001. Success of cannulation in Group (S) was 95 %, where as in Group (I) was 92.5%. In Group (S) 85% cannulas were secured in 1 st attempt, 10% in 2 nd attempt and 5% had failed cannulation. In Group (I) 67.5% were secured in 1 st attempt, 25% in 2 nd attempt and 7.5% had failed cannulation. Complications in terms of arterial puncture, malposition and pneumothorax were comparable. All these parameters were not statistically significant between the groups with p value >0.05. Supraclavicular approach is better than infraclavicular approach in terms of less mean time required for successful cannulation. Conclusion: Subclavian venous catheterization via the supraclavicular approach is aquicker method of central venous access in anesthesia.

“…Using the deltoid tuberosity approach, the cutaneous puncture site is placed 1.5 cm inferior to the medial border of this landmark, and the needle is advanced toward the sternoclavicular joint and sternal notch 44. Other landmarks described include the coraco-clavicular line45 and the deltopectoral triangle 46,39…”
Central venous cannulation is a commonly performed procedure which facilitates resuscitation, nutritional support, and long-term vascular access. Mechanical complications most often occur during insertion and are intimately related to the anatomic relationship of the central veins. Working knowledge of surface and deep anatomy minimizes complications. Use of surface anatomic landmarks to orient the deep course of cannulating needle tracts appropriately comprises the crux of complication avoidance. The authors describe use of surface landmarks to facilitate safe placement of internal jugular, subclavian, and femoral venous catheters. The role of real-time sonography as a safety-enhancing adjunct is reviewed.
“…It can augment the spectrum of catheterization possibilities, even in mechanically ventilated patients. [13] It is also an easy cannulation technique for the inexperienced physician and a useful alternative to traditional approaches for the experienced physician. [8]…”
The supraclavicular approach was first put into clinical practice in 1965 by Yoffa and is an underused method for gaining central access. It offers several advantages over the conventional infraclavicular approach to the subclavian vein. At the insertion site, the subclavian vein is closer to the skin, and the right-sided approach offers a straighter path into the subclavian vein. Also, this site is often more accessible during CPR and surgical procedures. In patients who are obese, this anatomic area is less distorted and in patient with congestive heart failure and cervical spine instability repositioning is not required.
