Objective: To compare the effects of blunt separation combined with early sheath removal and conventional catheterization on the incidence of bleeding, exudation and subcutaneous congestion after peripherally inserted central catheter (PICC). Methods: 250 patients with PICC catheterization in our hospital were selected, including 125 in the control group and 125 in the observation group. The conventional catheterization method was used in the control group: The sheath was removed by scalpel skin expansion and complete tube delivery in place. The observation group used blunt separation combined with early sheath removal. The success rate of one-time sheath delivery, immediate bleeding, 24-hour bleeding and exudation were compared. Results: The success rate of sheath delivery in the observation group was 100%; The amount of immediate blood loss and blood loss 24h after catheterization in observation group was obviously lower than that in the control group, with statistical significance (P < 0.05). There were 6 cases of exudation in the control group and no exudation in the observation group. There was significant difference in the incidence between the two groups (P < 0.05); There were 10 cases of subcutaneous congestion in the control group and 2 cases of subcutaneous congestion in the observation group. There was significant difference in the incidence between the two groups (P < 0.05); Conclusion: Blunt separation combined with early sheath removal can reduce the occurrence of local blood and fluid leakage after PICC catheterization.
