Abstract: Objective To explore the nursing effect of quality control circle(QCC)activity intervention for class A healing of abdominal incision and complications in obese puerperas after cesarean section. Methods A total of 86 obese pregnant women underwent cesarean section were randomly divided into control group and observation group, with 43 cases in each group. The control group was given routine postpartum care, and the observation group was given QCC intervention on the basis of routine postpartum care. The class A healing rates of abdominal incision on the 5^th and 10^th day after delivery were recorded in both groups, and the healing time of incision and incision-related complications were compared between two groups. Results There was no significant difference between the two groups in the class A healing rate of abdominal incision on the 5^th day after delivery(P>0.05). The class A healing rate of abdominal incision on the 10^th day after delivery in the observation group was 90.70%, which was significantly higher than 72.09% in the control group, and the healing time of incision was(7.89 ± 1.65)d in the observation group, which was significantly shorter than(8.74±2.03)d in the control group(P<0.05). The incidence of incision-related complications in the observation group was 6.98%, which was significantly lower than 23.26% in the control group(P<0.05). Conclusion On the basis of routine nursing after cesarean section, QCC intervention can effectively promote the class A healing of abdominal incision and shorten the healing time of incision, and reduce the incidence of incision-related complications.
