“…2,3 Accurate catheter placement is a major determinant of successful continuous peripheral nerve block (PNB), and incorrect positioning of catheters occurs in up to 40% of cases, 4,5 leading to an alarmingly high rate of secondary block failure. The recent introduction of stimulating catheters 6,7 and ultrasound 8,9 has improved the accuracy of catheter positioning; however, catheter dislodgement and leakage at the insertion site remain well-recognized but largely unresolved problems. Leakage from the catheter insertion site 10 presents a possibility of catheter dislodgement due to the loss of adhesion of material used to hold the catheter in place.…”

Less leakage and dislodgement with a catheter-over-needle versus a catheter-through-needle approach for peripheral nerve block: an ex vivo study Moins de fuites et de déplacements avec un cathéter par-dessus l'aiguille qu'avec un cathéter à travers l'aiguille pour un bloc nerveux périphérique: une étude ex vivo Abstract Purpose The objective of this study was to compare the catheter-through-needle (CTN) and catheter-over-needle (CON) catheterization techniques ex vivo by measuring leak pressure around the catheter and the catheter's resistance to pulling force. Methods Using an ex vivo porcine limb model, we compared the conventional CTN design with the CON design with respect to the ability to resist leakage at the catheter insertion site under high injection pressure and the force required to withdraw the catheter from tissue. One CON assembly (MultiSet, Pajunk) and three CTN assemblies (Contiplex, B.Braun; StimuCath, Arrow; Stimulong Sono, Pajunk) were studied. Ten porcine hind limbs were used to test leakage and another ten were used to measure withdrawal force. Catheters were placed at angles of 15°and 30°at depths of 3 cm and 5 cm. Leakage was assessed visually at the insertion site, and pressure was measured at the moment leakage occurred. Withdrawal force was measured by pulling the catheter from the tissue. Results No evidence of leakage was detected at the CON catheter insertion site at the highest pressure applied (1,000 mmHg) (n = 40). The CON assembly withstood significantly higher injection pressure than the CTN catheters without causing leaks at the catheter insertion site [CON, mean (standard deviation) [ 1,000 (0)
