Thus, in this study, we aimed toevaluate the effect of topical aloe vera gel on umbilical cord complications. Methods: This randomized clinical trial was performed in maternity ward of Ghaem Hospital, Mashhad, Iran The samples were selected through convenience sampling and were randomly divided into three groups of aloe vera, control, and placebo. For data analysis, One-way ANOVA test was conducted. Results: Comparison of cord condition between the groups showed significant differences between the three groups. In the placebo group, the number of infants with redness around the cord was significantly higher compared to the control (P=0.002) and aloe vera (P=0.002) groups. In addition, cord swelling was significantly more frequent in the placebo group than the control (P=0.002) and aloe vera (P=0.002) groups. The incidence of cord infection was significantly higher in the placebo group than the control (P=0.000) and aloe vera (P=0.000) groups. The occurrence of infection in the umbilical cord of the newborns in the placebo group was significantly more compared to the control (P=0.000) and aloe vera (P=0.000) groups. Conclusion: Topical aloe vera gel accelerated cord separation and reduced the rates of complications and infections.
