Each post op fracture’s patient will definitely experience pain due to the process of the surgery and the<br />system injury. Generally health worker just applied in pharmacology but there are still ways of non<br />pharmacological could help to lower the pain effectively, one of which is in relaxation technique of deep<br />breathing. The purpose of this research is to analyze the effect of relaxation techniques of deep breathing<br />against pain intensity on post op fracture’s patient. This research design uses pre experiments with onegroup<br />pretest-postest design. The population of this research are patients post op fracture with Purposive<br />Sampling sampling and taking with a total sample of 28 people. The independent variable in this study is<br />relaxation technique of deep breathing, whereas variables dependent is a decrease intensity of the pain. Data<br />was collected using the observation sheet with data analysis using statistical tests Willcoxon (α = 0.05). The<br />results showed that relaxation techniques of deep breathing in effect on the intensity of pain that is severe<br />pain from the previous 17 to 8 people. There is a connection between breath relaxation techniques in taking<br />action against the intensity of the patient's pain post op fracture with the results of the test statistics p =<br />0.000. The conclusion of relaxation techniques of deep breathing in having an impact on decreasing pain in<br />patients post op fracture.
