Background: Evidence-based practice (EBP) is a problem-solving approach to the delivery of Health care that integrates the best evidence from studies and patient care data with clinician expertise and patient preferences and values. Aim: to determine the impact of nursing intervention for women underwent cesarean section on the occurrence of post operative complicationsusing evidence based approach. what the impact of nursing intervention for women underwent cesarean section on the occurrence of post operative complications. This could enrich obstetrics and gynecological body of knowledge with evidence based practice to reduce postoperative problems. Hypothesis; women who received the standardized nursing care following CS experience less postoperative problems than those who only received routine nursing care of the hospital. Subject and Methods: The study was carried out in the obstetric and gynecological departments in Port Said Hospitals using a quasi-experimental study. This study was carried out in the obstetric and gynecological department at three governmental hospitals located in Port Said city: Port Said general hospital, Port Fouad hospital and El-tadamon hospital. The sample constituted 250women; the study subjects were divided into two equal groups of 125 parturient women each, as follows: Group A; the study group, who receive postoperative care program. Group B; the control group who receive postoperative routine hospital care after cesarean section. Data were collected using four tools devised specifically for the study. Results: Women in the study group were more likely to move early out of bed after the operation than the control group (64.0% vs. 8.8% respectively).  Most of women a higher percentage was able to start fluid intake within less than 2 hours. Almost two thirds of the study group early initiated breast feeding (<2 hours from C/S) compared to those in the control group. Conclusion: implementation of a nursing intervention for women undergoing cesarean section leads to improve the mother's level of knowledge, compliance of comprehensive care and practice .There was difference between the impacts of nursing intervention for women undergoing cesarean section on the occurrence of postoperative complications. The nursing intervention program can be used as a basic teaching model for women undergoing cesarean section. The intervention program can be used as integral part in post operative care and may be supplemented with booklets and pamphlets.
