OBJECTIVE: To know the pain intensity experienced by the patients using the two different syringes keeping the needle size constant.
MATERIALS AND METHODS: The split-scalp, single-blind study was conducted in patients after obtaining informed consent. On half of side, 1-mL syringe with 30-G needle was used whereas on the other half, 3-mL syringe with 30-G needle was used. On each side, about 10 mL of anesthetic solution (1% Xylocaine with epinephrine in 1:100 000 dilution) at the room temperature was injected. After the injections, the patients were asked to rate the pain experienced by using the Wong-Baker Faces pain scale. The data were analyzed statistically using Mann-Whitney's U test.
RESULTS: A total of 20 patients included 16 male and 4 females. The mean age in the males was 31.6 years and 28.8 years in females. The mean pain scale with 1-mL syringe was 2.7 anteriorly and 2.45 posteriorly (P < 0.01), whereas the mean pain score with 3-mL syringe was 4.5 anteriorly and 4.25 posteriorly (P < 0.01). The mean pain score with anterior injections in males was 2.5 vs 3.5 in females (1-mL syringe) and 4.3 in males vs 5.5 in females (1-mL syringe). Similarly, the average pain score with posterior injections was 2.4 in males vs 2.8 in females (1-mL syringe) and 4.2 in males vs 4.5 in females (3-mL syringe), respectively (P < 0.01).
CONCLUSION: The pain intensity is affected by syringe size.
