RESUMO
Objective To explore the effects of application of one-hand double-lumen simultaneous locking tech-nique on reduction of occlusion using high pressure resistant double-lumen PICCs. Methods Convenience sampling method was used to recruit 73 patients assigned into the experimental group,using one-hand double-lumen simulta-neous locking technique;66 patients were assigned into the control group,using routine locking method. The rate of PICC occlusion was recorded. Results The rate of incomplete occlusion was 8.22% in the experimental group,and 17.42% in the control group,the rate of complete occlusion in the experimental group was 0,and 0.76% in the control group,and the difference was statistically significant(P<0.05). Conclusion The one-hand double-lumen simul-taneous locking technique is easy and convenient to conduct. It can effectively reduce occlusion using high pres-sure resistant double-lumen PICCs.
