Objective : The aims of this study were to identify the post-operative complications experienced by women delivered by cesarean section, to find out the association between such complications and various maternal factors, and to plan and implement a program for upgrading nurse's knowledge and skills pertaining to the management of patients undergoing cesarean section. Setting: Zagazig University Maternity hospital. Sample: Two samples were selected for this study, 300 of parturient women coming for delivery, after 28 weeks of gestation, A systematic random sample was consecutively recruited among those women, either primi or multigravida, and undergoing cesarean section whether elective or emergency, and with any type of cesarean section. The other sample were 20 secondary school diploma nurses at different ages, and with different years of experiences. Tools for data collection: Women interview questionnaire, Women observation checklist, Follow up sheet, Nurses' knowledge questionnaire, Nurses' performance observation checklist and Nursing Training Program. Results: There was a significant association between post operative complications and various maternal factors such as age, income, education, job status, residence and body mass index. There was a positive relation between complications and type of anesthesia, type of caesarean section and duration of operation. More complications were due to repeated caesarean section, placenta previa, toxemia and failed induction of labor. Fewer complications were due to cephalo pelvic disproportion and mal presentation.
