Abstract: Abstract：Objective To explore the effects of 30° - angled incision fixer on controlling the bleeding after ultrasonography guided peripherally inserted central catheter (PICC) operation. Methods Sixty hospitalized patients treated with PICC therapy during February 2016 to October 2016 were recruited. All participants were randomly divided into case and control groups, each group had 30 people. In case group, the skin was longitudinal incised with the help of 30°- angled incision fixer, while in control group, the skin was traditionally longitudinal incised with experience. The bleeding amount was compared during operation, the next day and the 7th day after operation between two groups. Results The bleeding amount was significantly decreased during operation and the next day after operation in case group compared with that of control group (P＜0.05), while no difference was observed in bleeding amount on the 7th day after operation between the two groups (P＞0.05). Conclusion The 30°-angled incision fixer could make the angle and depth of the incision more precise, thus could narrow the range of wound and reduce the bleeding amount, and it deserves to be popularized and used clinically.
