Objective To analyze the effect of perioperative health education on wound aesthetics and complications of cesarean section. Methods A total of 200 pregnant women admitted to our hospital from October 2021 to July 2022 were randomly divided into control group and observation group, with 100 pregnant women in each group. The control group received routine nursing, and the observation group increased perioperative health education. The nursing effect, complications and breastfeeding were compared between the two groups. Results The total effective rate of nursing in the observation group was higher than that in the control group (P<0.05). The incidence of complications in the observation group was lower than that in the control group (P<0.05). The success rate of breastfeeding in the observation group was higher than that in the control group (P<0.05). Conclusion Perioperative health education can improve the wound aesthetics of pregnant women with cesarean section, reduce the incidence of perioperative complications, and improve the success rate of breastfeeding.
