Abstract:Objective To investigate the dynamic titration of morphine hydrochloride tablets in children with advanced tumors.Methods Thirty-eight children aged 8~14 years old with advanced tumor pain treated in our hospital between October 2017 and July 2020 were randomly divided into traditional treatment group (traditional group, n=19) and dynamic titration treatment group (dynamic titration group, n=19). (1) Compare the pain numerical rating scale (NRS), the quality of life (QOL) score, and Karnofsky performance status (KPS) score before and after treatment within the groups; (2) Compare the NRS, QOL, and KPS scores before and after treatment between the two groups; (3) Compare the side reactions after treatment between the two groups.Results The number (rate) of negative titration was higher in the dynamic titration group than in the traditional group, and the difference was statistically significant (P<0.05). There was no statistically significant difference in the positive titration number (rate) between the two groups (P>0.05). The differences in NRS score, QOL score, and KPS score before and after treatment within the group was statistically significant (P<0.05). There were no significant differences in NRS score, QOL score, and KPS score between the traditional group and the dynamic titration group both before and after treatment (P>0.05). After treatment, the incidence rate of gastrointestinal side reactions in the dynamic titration group was lower than that of the traditional group, and the difference was statistically significant (P<0.05), while the incidence rate of other side reactions was not statistically significant between the two groups (P>0.05).Conclusion The dynamic titration method of morphine hydrochloride tablets was feasible, and could reduce the pain of children with advanced tumors, improve their quality of life, and enhance their performance status, as effective as traditional treatment. The dynamic titration method could increase or decrease the dose of analgesic drugs according to the degree of pain in the child, and the reduction of the dose would not cause an abnormal increase in the amount of subsequent analgesic treatment. The dynamic titration method could reduce the gastrointestinal side reactions caused by analgesic treatment. It provided a clinical reference for the reduction of analgesic drugs in analgesic treatment.
