Muscular injections are one of the most common medical procedures and nurses encounter the experience of pain in their patients and look for ways of reducing pain. This quasi-experimental research was conducted to study the effects of Z-track and air-lock injection methods on the intensity of pain. 585 women referring to Heshmatiyyah Clinic in Sabzevar, Iran for either of three injections (Penicillin, B-complex, Diclophenac) were randomly assigned into three groups of 195 members; in each group, 65 patients received Ztrack 65 air-lock and the last 65 routine methods of injection in lateral position. Visual scale was utilized for pain assessment. Findings revealed that in Z-track group, intensity of pain was 3.1; while it was 4.1 and 4.5 in air-lock and routine injection groups; the difference was found to be significant by one -way ANOVA. Severe pain was experienced by 4.1% in Ztrack group, 7.7% in air-lock and 14.4% in the routine injection methods; Chi-squre revealed a significant relationship between pain intensity and injection method (P<0.0001). However, no significant relationship was found to exist between intensity of pain and factors such as age, occupation, education, and BMI. Therefore, it is suggested that we make use of Z-track injection for the ease of patients.
