Randomized Controlled Trial Comparative Study Clinical Trial
Comparative study on proper placement of central venous catheters with & without stillete.
Observing a standard protocol, central venous catheterization was performed, via the right basilic vein, in 100 patients. At random, 50 patients received a catheter with stillete and 50 without stillete. Catheter tip was localized on a chest radiograph; 78 per cent with stilletes and 80 per cent without stilletes were properly positioned (either in the right atrium or the superior vena cava). ⋯ Eight per cent of catheters with stillete and 6 per cent without stilletes were malplaced into the ipsilateral internal jugular vein. The incidence of proper and improper placement was similar with the two types of catheters. Silent catheter migration into the right ventricle is very frequent than recognized when an estimated catheter length is inserted without radiologic control.

Randomized Controlled Trial Comparative Study Clinical Trial
High versus low approach for internal jugular cannulation with double lumen catheters.
Double lumen cannulae were inserted through the right internal jugular vein (IJV) in 100 children, undergoing open heart surgery. High approach (n = 50, group I) of IJV cannulation was compared with low approach (n = 50, group II). In both the groups, hydromer coated double lumen polyurethane cannulae (Hydrocath) were introduced using Seldinger's technique; 98 per cent success rate was achieved in both the groups. ⋯ One patient in group I had carotid artery puncture. Catheter blockage occurred in one patient each in both the groups. Double lumen catheters are easy to insert and offer two lumens through single puncture site.
