“…In this study, the incidence of leakage was signi cantly lower in the CON group than in the CTN group. Yu and Nogawa reported that there were no leaks during catheter insertion using a CON needle [7,9]. Our results showed 10 leaks out of 30 CON cases, and the incidence of leaks was higher when using CON needles than in the previous studies.…”

“…In a recent study, leakage at the catheter insertion site was observed in 55% of patients using the CTN method, whereas there was no leakage using the CON method. [ 8 ] Although it was dependent on different operators and different insertion sites, leakage at the catheter insertion site has been reported to occur in 3% to 30% of perineural catheters using the CTN method. [ 11 ] As reported in several articles, the CTN method has the problem of leakage at the catheter insertion site, so suturing the catheter has been mainly used to resolve this problem.…”

“…In previous studies, the leakage rates in the CTN and CON methods were 55% and 0%, respectively. [ 8 ] In this study, assuming that the difference in the leakage rate was approximately 30% between the 2 methods, the sample sizes were measured to be 32 patients with type I (α) and type II (β) errors of 0.05 and 0.2, respectively. Taking into account the 10% dropout rate, the sample size was 35 patients in each group.…”

“…Rika Nogawa et al [ 11 ] compared the incidence of leakage from the catheter insertion site during continuous femoral nerve block when using the catheter-through-the-needle and catheter-over-needle methods. They found the incidence of pericatheter leakage in eleven of 20 patients in the catheter-through-needle group.…”
