Logistic regression analysis on correlative factors of phlebitis caused by iron sucrose injection

Objective To explore the correlative factors of phlebitis caused by iron sucrose injection through intravenous drip in Department of Orthopedics so as to provide a basis for take pertinently preventive steps. Methods A total of 588 inpatients with iron sucrose injection through intravenous drip in Department of Orthopedics of West China Hospital, Sichuan University were selected, by convenient sampling from December 2016 to May 2017. This research recorded the ages, sexes, whether they were with hypertension, body mess index (BMI) , vascular condition, retaining time and models of detaining needle, concentrations of iron saccharate, daily infusion quantity, days using iron saccharate, seniority of puncture nurses, whether there were with phlebitis through the correlative factors of phlebitis caused by iron sucrose injection through intravenous drip record sheet. Single factor and multiple factors Logistic stepwise regression was used to analyze the influencing factors of phlebitis. Results There were 69 cases (11.73%) with phlebitis in patients with ron sucrose injection treatment. Single factor analysis showed that there were statistically significant differences in the incidence of phlebitis among different sexes, daily infusion quantity, vascular condition, retaining time of detaining needle, type of detaining needle concentrations of iron saccharate of patients (χ2=8.654, 32.587, 68.313, 136.206, 10.662, 10.191; P<0.05) . Logistic regression analysis revealed that the independent risk factors of phlebitis caused by iron sucrose injection through intravenous drip included daily infusion quantity, retaining time of detaining needle, concentrations of iron saccharate, and the protective factors of that involved the vascular condition and the type of detaining needle. Conclusions Take pertinently preventive steps actively when patients in Department of Orthopedics are with iron sucrose injection through intravenous drip so as to lessen the suffering of the patients.
