Comparison of ultrasound-guided modified Seldinger technique versus blind puncture for peripherally inserted central catheter: a meta-analysis of randomized controlled trials

that ultrasound-guided MST was not significantly associated with improvement in first-attempt success (RR = 1.07, 95% CI 0.99 to 1.16, P=0.090) compared with the traditional blind puncture, but ultrasound-guided MST significantly reduced the incidence of complication after surgery (RR = 0.24, 95% CI 0.08 to 0.76, P = 0.015). In summary, ultrasound-guided MST is superior to the traditional blind puncture technique for PICC, especially for postoperative complications. It should be generalized to clinical application for PICC.
