A randomized controlled study on the clinical application of 'Flying Needle' painless phlebotomy technology

Venipuncture-related pain and needle fear can reduce patient cooperation and worsen the phlebotomy experience. This study was a comparative study conducted on 600 outpatients of Xiamen Humanity Hospital from September to December 2022, aiming to explore the application effect of the 'Flying Needle' painless phlebotomy technology (a method of accurately, quickly, and painlessly inserting a needle into a vein for blood collection). The study adopted a random grouping method, dividing the 600 included patients into an experimental group and a control group to ensure the comparability of baseline data between the two groups. The two groups of patients adopted different phlebotomy. The experimental group used the 'Flying Needle' phlebotomy method, while the control group used the normal phlebotomy method. During the study, multiple indicators of the two groups were observed and compared, including pain score during phlebotomy, fear score before and after phlebotomy, occurrence of adverse events during phlebotomy, patients' satisfaction with phlebotomy services, hemolysis of blood samples, and success rate of phlebotomy. Baseline data comparison showed that there were no statistically significant differences in gender, age, and body mass index (BMI) between the experimental group and the control group (p > 0.05), indicating good comparability between the groups. The comparison results of core indicators were as follows: in terms of pain score, the experimental group (1.96 ± 1.42) was significantly lower than the control group (2.87 ± 1.42), with a statistically significant difference (p < 0.001); in terms of the adverse event scores (with higher scores indicating more severe events), the experimental group (0.25 ± 0.59) was significantly lower than the control group (0.52 ± 0.87), with a statistically significant difference (p < 0.001); in terms of fear score, the post-phlebotomy fear score of the experimental group (1.49 ± 0.90) was not only significantly lower than that of the control group (1.67 ± 0.85) (p = 0.025), but also significantly lower than the pre-phlebotomy fear score of the experimental group itself (1.75 ± 0.91) (p < 0.001); in terms of patient satisfaction, the experimental group (97.00%) was significantly higher than the control group (83.00%), with a statistically significant difference (p < 0.001). In addition, there were no significant differences in blood sample hemolysis and phlebotomy success rate between the two groups. The 'Flying Needle' technique has rapid insertion, a short process, minimal damage, reduces pain, adverse reactions, and fear, and improves satisfaction. It has good potential and is worthy of promotion.
