AbstractWe investigated the prophylactic antiemetic effect of added low-dose infusion of propofol in patients exhibiting nausea and vomiting refractory to dexamethasone and serotonin antagonist during non-cisplatin chemotherapy for breast cancer. In a prospective open longitudinal study, 117 patients who had more than five episodes of nausea and vomiting in their first chemotherapy cycle during the first 24 hr completed the study. They received in addition to the usual prophylactic antiemetic regimen a continuous intravenous infusion of 1 mg.kg-1.hr-1 propofol started four hours before chemotherapy and continued up to 24 hr for the two subsequent cycles. The number of vomiting/nausea episodes, level of sedation, patient activity, appetite and preference for future chemotherapy cycles were assessed. In the propofol supplemented cycles 90 and 80% of patients, during the 1st and 2nd propofol-assisted cycle respectively, were free of nausea and vomiting during the first 24 hr after chemotherapy. Patients were more frequently active and had more appetite during the propofol-assisted cycles. No propofol-associated side effects were observed. We conclude that the addition of a subhypnotic infusion of propofol enables better control of nausea and vomiting caused by non-cisplatin chemotherapy in the first 24 hr post-treatment.
