Detection of the serum level of lithium in patients with psychosis and its influece factors / 中国基层医药

ABSTRACT

Objective To monitor the lithium level in serum of patients who has taken lithium carbonate and analyze its influencing factor,to explore the relationship between lithium level in serum and chronic lithium intoxication.Methods The lithium level was determined by electrolytic analyzer with electrode method and results from September in 2011 to September in 2012 were retrospectively analyzed.Results The lithium levels of 252 cases were 56cases (22％) under 0.6mmol/L,188 cases (75 ％) between 0.6-1.2mmol/L and 8 cases (3％) above 1.2mmol/L.179 cases (71％) were effective and 69 cases (27 ％) were ineffective,4 cases (2％) showed lithium toxic.The clinical therapeutic effect was improved with the concentration gradually in creasing,and the poisoning rate was getting higher.Plasma lithium concentration is closely related to hyperlipoidemia,hemolysis,nephropathy and the incidence seasons.Conclusion We should attach importance to the therapy drug monitoring dosage,clinical feature,and removing influencing factor which are the basis to guide the clinical medication.This way can adjust the dosage for individual administration.
