静脉留置针改良正压封管技术应用效果观察

[摘要] Abstract：Objective To evaluate the application of modified positive pressure sealing technology for intravenous detaining trocar. Methods 〓A total of 100 patients using venous indwelling catheter were randomly divided into the control group and the observation group, with 50 cases in each group. The pulsed positive pressure sealing method for intravenous detaining trocar was used in the control group, while the modified positive pressure sealing technology was applied in the observation group. The rate of blood return, blockage, phlebitis and catheter indwelling time were compared between two groups. Results 〓The rate of blood return in trocar, blockage and catheter-related phlebitis were lower in the observation group than those of controls(P<0.05). The catheter indwelling time was longer in the observation group than that of controls(P<0.01). Conclusion 〓Modified positive pressure sealing technology is potentially effective to reduce the rate of blood return in trocar, blockage and catheter-related phlebitis in patients receiving indwelling catheter.
