RESUMO
Objective To discuss the clinical application value of gelatin sponge in the extraction of children's multiple teeth.Methods From July 2014 to July 2017,100 children with multiple teeth in the Children′s Hospital Affiliated to Zhengzhou University were selected,and they were divided into two groups by random number table method,with 50 cases in each group.The observation group after routinely removal of supernumerary tooth,according to the size of the tooth extraction wound,chose proper absorbability gelatin sponge after tamping,para suture wounds,while the control group received routine hemostasis,para suture wounds without stuffing.The postoperative bleeding,pain and infection were compared between the two groups.Results The incidence rate of postoperative hemorrhage in the observation group was 2％,which was lower than 16％in the control group,and the difference was statistically significant(χ2 =4.40,P<0.05).The incidence rate of postoperative pain in the observation group was 18％,which in the control group was 20％,there was no statistically significant difference between the two groups(χ2 =0.06,P>0.05).No infection was found in the two groups.Conclusion Gelatin sponge can be used as one of the effective means of preventing postoperative bleeding in children.
