Objective To analyze the effects of different treatment methods on blood donors with haematoma(or bruise) after blood donation. Methods 147 blood donors with haematoma(or bruise) after blood donation in our blood station were randomly selected. According to the difference of treatment methods, they were divided into group A (n=66), group B (n=48) and group C (n=33), for the group A of blood donors to carry out cold and hot compress method, for the group B blood donors to implement the potato slice application method, for the group C blood donors to implement the hi-treatment ointment external application method. Results The total effective rate of group B blood donors was higher than that of group A blood donors. The difference was statistically significant (χ²=4.63,P＜0.05). The total clinical effective rate of group C blood donors was higher than that of group A blood donors. There is statistical significance (χ²=13.99,P＜0.05). The total effective rate of donors in group C was higher than that in group B. The difference between the two groups was statistically significant (χ²=3.99,P＜0.05). Conclusion The effect of external application of Hirudoid(Mucopolysaccharide Polysulfate Cream) on blood donors after blood donation is effective, which may improve their physical and mental health.
