Concurrent and Close Temporal Administration of Lithium and ECT.
The clinical effects of concurrent and close temporal administration of electroconvulsive therapy (ECT) and lithium (Li) were investigated by chart review. Three groups of patients were compared on the basis of ECT-related complications, total length of hospital stay (LOS), and post-ECT hospital stay. The groups consisted of patients administered concurrent ECT and Li (n = 27); patients administered Li within 24 h prior to ECT or within 48 h post-ECT (n = 49); and patients administered ECT without concurrent or close temporal administration of Li (n = 100). Prolonged or severe post-ECT confusion was significantly associated with close timing of administration of Li relative to the ECT course. The groups did not differ in the number of complications or the total LOS, although the post-ECT LOS was significantly longer in the group administered Li in close temporal association with ECT. These data suggest that caution should be exercised in the combined use of these treatment modalities.
