However, till now the infraclavicular OA approach for SCV cannulation have not been studied. Hence, we planned this study to compare the success rate and safety of short axis (SA) and OA approaches, during US guided infraclavicular SCV cannulation.Methods In this randomised trial, 200 patients requiring SCV cannulation were randomised to either SA or OA groups ( figure 1). During cannulation following parameters were recorded: success rate, visualisation time (VT), puncture time (PT), insertion time (IT), catheterisation time (CT) , total procedural time (TPT), first puncture success rate, number of needle redirections, number of skin punctures and number of vessel punctures. The incidence of mechanical complications (haemothorax, pneumothorax, arterial puncture), catheter misplacements and infection were also recorded.Results Cannulation was successful in 188 patients {Group OA 92% vs 96% respectively (p value= 0.233)}. Mean VT. PT, IT, CT and TPT were comparable between groups. Group SA required less time for venous puncture and compared to group OA . Pneumothorax was significantly higher in SA group (5.43%) compared to OA group (0%).

The time for venous puncture, catheterization and first attempt success rate were similar in both the groups. Hence, OA may be the preferred technique for infraclavicular subclavian vein cannulation compared to that of SA.",
