Application value of the improved blunt separation technique in peripherally inserted central catheter in thrombocytopenia patients

ObjectiveTo investigate the application effects of the improved blunt separation technique in peripherally inserted central catheter(PICC) in thrombocytopenia patients.

MethodsA total of 44 normal clotting function patients with platelet count less than 100×10⁹/L treated with PICC were randomly divided into the observation group(23 cases) and control group(21 cases).The control group was cathetered with the tearable sheath and dilator to assemble blunt separation method to expand the skin, and the observation group was cathetered with the improved blunt separation technique.The success rate of primary sheath delivery, pain degree at the puncture site after 1, 3 and 5 days of cathetering, bleeding volume after 24 h of cathetering and maintenance times within 7 days were compared between two groups.

ResultsThe success rates of primary sheath delivery in observation group and control group were 95.65%(22/23) and 85.71%(18/21), respectively, and the difference of which was not statistically significant(P>0.05).The pain degree in observation group was lower than that in control group(P < 0.05).The number of layers of errhysis gauze at puncture point within 24 h of cathetering and times of dressing change within 7 d of cathetering in observation group were less than those in control group(P < 0.05 and P < 0.01).

ConclusionsImproved blunt separation technique can significantly reduce the bleeding volume at the puncture point and number of catheter maintenance, relieve the pain and tension, and improve satisfaction of thrombocytopenia patients.It is worthy of promotion.
