Table 2 Central venous catheter (CVC) and CVC securement characteristics in the two study groups

From: A clinical evaluation of two central venous catheter stabilization systems

  Suture group (n = 86) Suture-free group (n = 85) p value
Median (IQR) size (Fr gauge) of CVC 7 (7; 8.5) 7 (7; 8.5) 0.818a
Median (IQR) number of lumens 3 (3; 4) 3 (3; 4) 0.897a
Insertion site IJ:SC:FM (%) 34:28:24 (39.5:32.6:27.9) 36:25:24 (42.4:29.4:28.2) 0.895b
Hair removed from insertion site (%) 15 (17.4) 12 (14.1) 0.676b
Number of CVC with a box clamp (%) 27 (31.4) 3 (3.5) < 0.0001b
Mean (95% CI) external CVC length (mm) immediately following CVC insertiond 6.2 (3.9; 8.5) (n = 84) 16.2 (10.0; 22.3) (n = 84) 0.299a
No. of catheter days with assessment (%) 532 (91.3) 643 (90.4) 0.610c
Mean (95% CI) duration (days) the CVC in place 6.8 (5.5; 8.1) 8.4 (6.6; 10.1) 0.162a
Median (IQR) time (min) to apply CVC securement 3 (2; 6.5) (n = 79) 5 (3; 5) (n = 78) 0.184a
Median (IQR) time (min) to replace CVC dressing/securement device 7 (5; 10) (n = 90) 10 (5; 10) (n = 129) 0.006a
Median (IQR) time (min) to remove CVC dressing/securement device 3 (2.5; 5) (n = 25) 2 (1; 4) (n = 29) 0.08a
  1. Patients were randomized to receive either sutures and a Tegaderm™ IV Advanced dressing (suture group) or 3M™ PICC/CVC Securement Device + Tegaderm™ IV Advanced dressing (suture-free group) to secure their CVC onto the skin [n = number of CVC or CVC days (IQR or %)]
  2. IJ, internal jugular vein; SC, subclavian vein; FM, Femoral vein
  3. aMann–Whitney test; bFisher’s exact test; cPearson’s Chi-square; dexternal CVC length measured in millimetre from the CVC skin entry point to the moulded junction of the CVC hub
