Purpose: To compare the effect of tunneled and nontunneled peripherally inserted central catheter placement under B-mode ultrasound. Methods: A single center, randomized, controlled, nonblinded, prospective trial was conducted in Guangzhou, China, between July 2018 and May 2019. A total of 174 participants were randomized to the experimental group (tunneled peripherally inserted central catheter) or the control group (nontunneled peripherally inserted central catheter) and were followed until extubation. Basic characteristics, peripherally inserted central catheter characteristics, the incidence of complications, and the costs of peripherally inserted central catheter placement and maintenance were collected. Data were analyzed by intention-to-treat. Results: A total of 168 of the participants had successful peripherally inserted central catheter placements (85/87, 97.7% in the experimental group and 83/87, 95.4% in the control group, P = 0.682). Compared to the control group, the experimental group had a lower incidence of complications during the placement (18.4% vs 32.2%, P = 0.036), a lower incidence of wound oozing (27.6% vs 57.5%, P < 0.001), a lower incidence of medical adhesive–related skin injury (9.2% vs 25.3%, P = 0.005), a lower incidence of venous thrombosis (1.1% vs 9.2%, P = 0.034), a lower incidence of catheter dislodgement (1.1% vs 9.2%, P = 0.034), and lower costs of peripherally inserted central catheter maintenance at 1, 2, and 3 months ( P < 0.05). Conclusion: Tunneled peripherally inserted central catheter may be recommended for good effectiveness.

Objective To compare the value of the subcutaneous tunneling technique versus the normal technique in improving the outcomes of patients undergoing chemotherapy with peripherally inserted central catheters (PICCs). Methods One hundred thirty patients were randomly divided into an experimental group (subcutaneous tunneling technique) and control group (normal technique) according to the PICC placement technique, and clinical data were compared between the groups. Results In total, 129 PICCs were successfully inserted. Compared with the control group, the experimental group had a lower occurrence of complications after placement (especially catheter dislodgement: 3.1% vs. 15.4%, venous thrombosis: 3.1% vs. 15.4%, and wound oozing: 14.1% vs. 27.7%), lower occurrence of unscheduled PICC removal (3.1% vs. 13.8%), greater comfort during placement (14.16 ± 2.21 vs. 15.09 ± 2.49 on a scale ranging from 6 to 30 points, with higher scores indicating lower degrees of comfort), and lower costs of PICC maintenance (median (interquartile range) per-day maintenance cost: 13.90 (10.99–32.83) vs. 15.69 (10.51–57.46) Yuan). The occurrence of complications and amount of bleeding during placement were not significantly different between the two groups. Conclusions The subcutaneous tunneling technique can improve PICC placement by reducing complications and costs of maintenance with better patient comfort during placement.
