Effect of promotion of the flushing and locking technique during the utilization of the intravenous device on the catheter occlusion rate in the Specific Private Nursing Section, Maharaj Nakorn Chiang Mai Hospital.
Keywords:
Flushing and locking, IV care, Tip occlusionAbstract
Intravenous catheter tip occlusion is the most critical problem associated with the injection port intravenous catheter. The purpose of this quasi-experimental research was to study the effects of the promotion of the flushing and locking technique with the intravenous device on the practice rate versus the catheter occlusion rate pre and post the promotion. The promotion of the intravenous flushing and locking technique was carried out in the Specific Private Nursing Section, Maharaj Nakorn Chiang Mai Hospital, from July 1st, 2021 to February 28st, 2022. The study cohort included the nurses carrying out the catheterization and the patients who underwent injection via a port intravenous catheter. The study tools were a demographic recording form, an observation checklist form, a form to assess flushing and locking knowledge and an occlusion recording form. Occlusion rate and nursing practice pre and post the study were analyzed using the Chi-square test. Nursing knowledge pre and post the promotion was analyzed using a t test and a Wilcoxon Matched-Pairs Signed Rank Test. The results showed that the knowledge score was significantly increased (p<0.001), nursing practice significantly increased from74.66% to 95.33% (p<0.001), and the occlusion rate significantly decreased from 6.90% to 3.67% (p<0.001). Promoting the compliances of nurses with the practice of the flushing and locking technique for prevention of intravenous catheter tip occlusion reduced the occlusion rate and hence improved patient care. This study shows that multiple strategies should be employed to ensure the promotion is sustained and monitored continuously strategies supervision and monitor continuously.
