Objective:To investigate the effect of aromatherapy on improving sleep quality and nausea and vomiting in patients with concurrent chemoradiotherapy for cervical cancer. Method:From Apr. 2018 to May 2020, 124 patients with cervical cancer who admitted to the Department of gynecol. and surgery of a Grade-A tumor hospital in Fujian Province were selected as the research objects, according to the random number table method, they were divided into observation group and control group, 62 cases in each group. The control group was given conventional treatment and nursing measures, while the observation group was given aromatherapy on the basis of the control group. The National Cancer Institute common toxicity classification (NCI-CTC v4.0) and Pittsburgh sleep quality index (PSQI) were used to evaluate nausea, vomiting and sleep quality. Result:1 day before chemotherapy, there were no statistically significant differences in nausea, vomiting and sleep quality between two groups (P>0.05). On the 1st, 3rd and 5th day after chemotherapy, the nausea and vomiting scores of the observation group were all lower than those of the control group (P<0.05). On the 1st and 3rd day after chemotherapy, there were no statistically significant differences in sleep quality between the two groups (P>0.05). On the 5th day after chemotherapy, the sleep quality of the observation group was better than that of the control group (P<0.05). Conclusion:Aromatherapy is an economical, safe and simple adjuvant therapy, which can improve the sleep disorder of patients with cervical cancer undergoing concurrent chemoradiotherapy and reduce the nausea and vomiting associated with chemotherapy.
