Application of incision dilation and protection device in cesarean section

Objective To investigate the protective effect of incision dilation and protection device on incision in cesarean section. Methods Chose 754 cases of pregnant women who taken vaginal delivery transit cesarean section, and they were divided into observation group and control group according to the random number table method, 377 cases in each group.The observation group used extend the incision protector incision, the control group did not use incision dilation and protection device.All the women in the operation began to cut the skin before surgery and suture the skin before the end, subcutaneous tissue fluid was dipped to carry out bacterial culture, observed whether there was colony growth.The one year postoperative follow up was conducted to observe the wound infection and surgical site intrauterine membrane endometriosis incidence. Results The incision contamination rate of the observation group was lower than that of the control group(0.00% vs.13.79%), the incision infection rate was lower than that of the control group(1.33% vs.9.02%), the differences were statistically significant(χ2=55.852, 22.740, all P<0.05). In the observation group, 0 case of endometriosis and 2 cases in the control group were observed, the incidence of endometriosis in the observation group was lower than that in the control group, but the difference was not statistically significant(χ2=1.989, P=0.252). Conclusion Incision dilation and protection device using in cesarean section can significantly reduce the incision contamination rate, incision infection rate, prevent the occurrence of endometriosis.
