The results showed that during the venous blood sampling was a significant difference between the mean pain intensity of neonatal in the eye shield plus ear muffs group (3.14 ± 0.71), the ear muffs group (4.43 ± 1.21), the eye shield group (5.41 ± 1.04).) and the control group (5.94 ± 0.84) (P = 0.001). Moreover, after the venous blood sampling, there was a significant difference between the mean neonatal pain intensity in the eye shield plus ear muffs group (1.19 ± 0.39), the ear muffs group (1.43 ± 0.50), the eye shield group (1.33 ± 0.37) and the control group (1.89 ± 0.90) (P = 0.001).
