Abstract:
Objective To explore the effects of gadopentetate dimeglumine injection on renal function. Methods The study included 623 consecutive patients. Their serum creatinine concentrations before and within 3 days after injection of gadopentetate dimeglumine were analyzed. Their eGFR ( estimated glomerular filtration rate) were calculated. Patients were divided into two groups according to their injection dose: group received single dose and group received double dose. Patients in each group were subdivided into three subgroups according to their eGFR: subgroup of normal renal function, subgroup of mild renal insufficiency and subgroup of moderate renal insufficiency. Paried sample t test and group design paried sample Rank Sum test were used for statistical analysis. Results There was no adverse reaction oroccurrence of acute renal insufficiency. The mean level of serum creatinine dropped from (74. 0 ±17. 2) μ mol/L to (71.5 ± 19. 0) μ mol/L (t = 5. 39, P ＜ 0. 05 ) in 623 cases after injection of gadopentetate dimeglumine. However, the mean level of serum creatinine increased from (89.6 ± 12. 2 ) μmol/L to (92. 1 ± 14. 6) μmol/L ( t = 0. 68, P ＞ 0. 05 ) in subgroup of mild renal insufficiency under group received double dose and increased from ( 118. 3 ± 15. 3 ) μmol/L to ( 135.7 ± 8. 5 ) μ mol/L ( t = 2. 02, P ＜ 0. 05 ) in subgroup of moderate renal insufficiency under group received double dose, the mean level of serum creatinine dropped in all other subgroups. Conclusions Single dose gadopentetate dimeglumine is safe for patients with normal renal function and mild, moderate renal insufficiency in short term, but patients with abnormal renal function should be followed up after double dose injection.
