RESUMO
PURPOSE: The aim of this study is to assess the impact of lavender oil on odor elimination, ostomy adjustment and quality of life outcomes in patients with permanent colostomy. Specifically, the study aims to compare the outcomes of an experimental group receiving lavender oil intervention with those of a control group. METHODS: A randomized controlled trial design was employed, including an experimental group receiving lavender oil intervention and a control group receiving standard care. The study participants were patients with permanent colostomy. Various variables were assessed, including odor scale, work and social functioning, sexuality and body image, stoma function, financial concerns, acceptance, anxiety/preoccupation, social engagement and anger. RESULTS: The post-scores assessment showed significant differences between the experimental and control groups in all variables. The experimental group exhibited significantly more positive outcomes concerning the reduction of odor (p<0.001), performance in the workplace (p<0.001), body image connected to sexuality (p<0.001), stoma functionality (p<0.001), financial worries (p=0.005), acceptance levels (p<0.001), anxiety levels (p<0.001), social involvement (p<0.001), and irritability (p<0.001). Effect sizes were substantial (=0.88-0.98 in all variables but one), indicating significant differences in average scores before and after the intervention. CONCLUSION: The findings of this study suggest that lavender oil intervention effectively improved odor elimination, ostomy adjustment and quality of life outcomes in patients with permanent colostomy.
