Introduction: Coronary angiography is often associated with complications such as
hemorrhage and hematoma that should be considered and be minimized.
Objective: This study aimed to determine the effect of Zinc oxide scallop-shell powder as
a topical hemostatic agent (composed mainly of calcium) on complications after coronary
angiography. These complications include hemostasis time, low back pain, hemorrhage,
hematoma, the necessity of sandbags, and patient ambulation.
Materials and Methods: The current research was a blind, parallel, randomized clinical
trial done on 150 patients under coronary angiography. They were randomly divided into
three equal groups of A (control), B (case 1), and C (case 2). In group A, hemostasis was
done with manual compression, use of ChitoHem powder, putting sandbag for 4-6 h in
a supine position, and getting out of bed after 24 h. In group B, instead of ChitoHem
powder, we used Zinc oxide scallop-shell powder. In group C, hemostasis was done with
manual compression, Zinc oxide scallop-shell powder, putting sandbag for 1 h in a supine
position, and getting out of bed after 2 h. The duration of hemostasis, bleeding, and
hematoma after hemostasis and the severity of low back pain were investigated at 8 point
intervals during 24 h. Data analysis was done using descriptive statistics indicators and
Kolmogorov-Smirnov, ANOVA, Chi Square, Fisher exact test and Kruskal-Wallis tests.
Results: The Mean±SD ages of groups of A, B, and C were 60.08±11.32, 60.22±10.30, and
61.69±10.61, respectively, which was not statistically different. Furthermore, there was no
significant difference between these three groups regarding their demographic information.
There were statistically significant differences between groups about the amount of low back
pain at the second, third, and fourth h after angiography (P=0.001). There was a significant
difference in the amount of bleeding between the three groups (P=0.017). The difference in
time of hemostasis in the three groups was not statistically significant.
Conclusion: The Zinc oxide scallop-shell powder reduces catheter site bleeding after coronary
angiography and bed rest time and ultimately the severity of low back pain. Performing a
similar study is recommended.
