Background: Pain management is the challenging concepts in health workers. Since neonates have higher pain sensitivity in compare to childhood and adults. The objective of this study was to examine the pain relieving effect of breast feeding during immunization injections in healthy neonates. Methods and Materials: In this control randomized clinical trial, Samples were divided two groups (by age and sex) of 76 healthy 2- 4 months old term infants. In breast-fed group, 2 minutes before, during, and 15 seconds after the DPT immunization injection were in mother hug, and in control group as routine of clinic, were lied on the examining table during injection. Appearance of Neonates were observed and assessed by Modified Behavioral Pain Scale (MBPS) during 5 second before immunization to 15 second after it. Results: In breast fed and control group mean of age were 81.53±41.46 and 81.61±40.59 day and for weight were 6.65±1.17 and 6.70±1.14 kg for hight were 64.27±5.5 and 63.38±5.06 cm respectively. There were significant differences in Behavioral Pain Scores of two groups include: facial expression (4 items), cry (5 items), and movements (6 items). (P<0.0001). There is no statistically significant difference between the 2 groups for age, sex and the time of feeding prior to vaccination Conclusion: Regarding to significant difference in behavioral of pain responds in two groups, it is suggested, with simple and safe intervention method of straight breast feeding reduce pain during immunization and muscular injections too.

Background: Labor pain, which is a natural, unique and multi- factorial pain, is considereds a major part of women's anxiety at reproductive ages. There are two pharmacological and non-pharmacological approaches for reducing this pain. Since the pharmacological approach involves side effects, lots of attention has recently been given to the non-pharmacological methods. One of these methods, is use inc birth ball the, which includes sitting and rocking on the birth ball. The purpose of this study was to evaluate the effects of using birth ball on labor pain, the duration of active phase and contractions of physiologic labor. Materials and Methods: In this randomized control-clinical trial, sixty primiparous women (18-35 year old) were selected and randomly assighed into birth ball and control groups. The severity of pain was measured through Visual Analogue Scale (VAS) and the pain score, interval between contractions and duration of active phase were compared between the two groups. Results: The average pain score in the birth ball group was significantly lower than the control group (p<0.05). In terms of interval between the contractions, duration of active phase and uterine contractions, there were no significant differences between the two groups. Conclusion: Although use of birth ball did not have any effects on the duration of active phase, uterine contractions and interval between uterine contractions, this complementary therapy reduced the severity of pain during the active phase of delivery. Therefore, this safe method is suggested to be used during normal vaginal delivery and physiologic labor. Also, conducting a study, which examines the effects of using a combination of complementary methods, is recommended
