| Background: To date, there has been no accurate information on whether the history of radiotherapy for
breast cancer can lead to increased nausea and vomiting in upper limb orthopedic surgery or not. Therefore,
the present study aimed to compare nausea and vomiting in upper limb orthopedic surgery candidates with
and without a history of radiotherapy.
Methods: In total, 90 paents (45 per group) who were candidates for upper limb orthopedic surgery during
2019‐2020 were selected by convenience sampling. In this research, post‐operative nausea and vomiting
(PONV) was assessed using the Rhodes Index. In addition, data analysis was carried out using the Shapiro‐
Wilk test and t‐test, and a P‐value of less than 0.05 was considered stascally significant.
Results: In this study, PONV was detected in 100% of the subjects with a history of breast radiotherapy, but
only 40% of the parcipants (n=18) without a history of radiotherapy experienced PONV (P=0.001). According
to the results, the mean and standard deviation of PONV in the group of patients with a history of
radiotherapy was reported to be 25.51±5.29, which was significantly higher than the group of subjects without a history of radiotherapy (14.19±3.45) (P=0.003).
Conclusion: According to the results of the present study, a history of breast radiotherapy could worsen nausea and vomiting after upper limb orthopedic surgery. |
