Caesarean section is an artificial birth where the fetus is born through an incision in the abdominal wall and uterine wall provided that the uterus is intact and the fetus weighs more than 500 grams. The incidence of caesarean section in Indonesia is 15.3%. Caesarean section surgery performed in an attempt to expel the baby will leave an incision wound condition. One of the factors that support the process of wound healing is early mobilization. Early mobilization carried out in stages will help improve blood flow thereby speeding up the wound healing process, especially during the inflammatory phase so that the mother can return to normal daily activities. This study aims to determine the effect of early mobilization on the wound healing process in the inflammatory phase of post sectio caesarea. The purpose of this study is to find out how early mobilization influences the wound healing process in the inflammatory phase of post sectio caesarea at Sufina Aziz General Hospital, Medan City in 2023. This study used a quantitative research method with the Quasi Experiment Design method with the One Group Pre-test Post-test Design. The population of all post caesarean section patients at Sufina Aziz Hospital in Medan City with a sample of 15 respondents used the Accidental Sampling technique. Data analysis in this study used the Paired Sample T-Test. The results showed that almost all respondents, namely 14 respondents, experienced wound healing in the inflammatory phase category either on the third day post caesarean section or after (post-test) early mobilization. The results of the Paired Sample T-Test obtained a p value (0.000) <? (0.05) which means that there is an effect of early mobilization on the wound healing process in the inflammatory phase of after caesarean sectionat Sufina Aziz Hospital, Medan City in 2023. Health workers are expected to increase professionalism in providing services to patients, especially in providing early post-sectio caesarea mobilization.
