Safety and Influencing Factors of Different Proportions of Piperacillin Sodium and Tazobactam Sodium in the Treatment of Severe Pneumonia
OBJECTIVE:To probe into the safety and influencing factors of different proportions of piperacillin sodium and tazobactam sodium in the treatment of severe pneumonia patients.METHODS:Incidence of adverse drug reactions(granulocytopenia,decreased platelet count,allergy and diarrhea)in patients with severe pneumonia treated with different proportions of piperacillin sodium and tazobactam sodium in the First Affiliated Hospital of China Medical University from Aug.2021 to Aug.2022 was retrospectively reviewed.According to the treatment regimen(related proportion of compound preparations),all patients were divided into the treatment group 1[with piperacillin sodium and tazobactam sodium(4 ∶1)]and treatment group 2[with piperacillin sodium and tazobactam sodium(8 ∶1)].Correlation between age,gender,previous disease,dosage,medication duration and adverse drug reactions was statistically analyzed.RESULTS:The incidence of adverse drug reactions in treatment group 1 was 79.61%(609/765),which was lower than 84.55%(476/563)in treatment group 2,the difference was statistically significant(P<0.05).Univariate Logistic regression analysis showed that the combination ratio of piperacillin sodium and tazobactam sodium 8 ∶1(OR=1.098,P=0.012)and prolonged length of stay(OR=1.029,P<0.001)were independent risk factors for adverse drug reactions(P<0.05).Multivariate Logistic regression analysis showed that age increase(OR=1.012,P=0.011)and prolonged medication duration(OR = 1.036,P = 0.013)were risk factors of total adverse drug reactions.CONCLUSIONS:Piperacillin sodium and tazobactam sodium(4∶1)has a higher safety in the treatment of severe pneumonia.Longer medication duration and length of stay may increase the incidence of adverse drug reactions in patients treated with piperacillin sodium and tazobactam sodium.
