“…Once the patients were under the adequate depth of anesthesia and prepared for the electrical stimulation, standard bitemporal ECT was administered. As previously described by Joo et al, [ 19 ] electrical parameters for the first treatment were set using the preselected-dose method according to MECTA Corporation. This method determines electrical parameters according to the sex and age of the patient, based on previous studies.…”

Although electroconvulsive therapy (ECT) is generally a safe therapeutic method, unexpected adverse effects, such as post-ECT delirium, may occur. Despite its harmful consequences, there has been little discussion about the predictors of post-ECT delirium. Thus, the current study aimed to clarify the factors associated with post-ECT delirium by reviewing electronic medical records of 268 bitemporal ECT sessions from December 2006 to July 2018 in a university hospital. Demographic and clinical characteristics of sessions involving patients with or without post-ECT delirium were compared. Multiple logistic regression analysis was applied to analyze the correlation between variables and post-ECT delirium. Post-ECT delirium developed in 23 sessions (8.6%). Of all the demographic and clinical variables measured, only etomidate use was significantly different between delirium-positive and delirium-negative groups after Bonferroni correction. The regression model also indicated that etomidate use to be significantly associated with post-ECT delirium. In this study, etomidate was associated with a higher risk of developing post-ECT delirium, an association that appeared unrelated to other possible measured variables. Practitioners should take into account the risk of post-ECT delirium while choosing anesthetics, so as to prevent early discontinuation before sufficient therapeutic gain is achieved.

Background: Electroconvulsive therapy (ECT) is the most important and safe nonpharmacological treatment for psychiatric disorders. Some patients experience unexplained fever after ECT, but only a few studies have reported on this. Method: We investigated fever after ECT by retrospectively reviewing the medical records of patients. Patients treated at the ECT unit of the Department of Psychiatry at Asan Medical Center, Seoul, South Korea, between 30 June 2004 and 30 June 2019, were included. Differences in variables were compared between groups with or without fever after ECT sessions. Result: There were 28 patients (8.8%) in the fever group. Forty-three ECT sessions (1.5%) resulted in fever after treatment. The female-to-male ratio was higher in the fever group than in the control group, and the mean number of total ECT sessions was also higher in the fever group than in the control group, but there were no other differences between the 2 groups. Conclusion: Comparing fever and control sessions, fever sessions relatively preceded control sessions and had a longer seizure duration. Postictal delirium occurred more often in the fever sessions than in control sessions. Fever sessions had a higher white blood cell count and lower concomitant quetiapine dosage than control sessions. Because 8.8% of patients who received ECT experienced fever after treatment more than once, fever after ECT is considered to be a common side effect.

“…These findings were not directly comparable to each other due to differences in the used pulse width, ECT devices, titration schedules, and age distributions. However, considering ethnicity may still be important in estimating IST in actual clinical practice [23,32,33].…”

ObjectiveThe present study aimed to report the initial seizure threshold (IST) of a brief-pulse bilateral electroconvulsive therapy (BP-BL ECT) in Korean patients with schizophrenia/schizoaffective disorder and to identify IST predictors. MethodsAmong 67 patients who received ECT and diagnosed with schizophrenia/schizoaffective disorder based on the criteria of the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision, we included 56 patients who received 1-millisecond BP-BL ECT after anesthesia with sodium thiopental between March 2012 and June 2018. Demographic and clinical information was gathered from electronic medical records, and a multiple regression analysis was conducted to identify predictors of the IST. ResultsThe mean age of the patients was 36.9±12.0 years and 30 (53.6%) patients were male. The mean and median IST were 105.9±54.5 and 96 millicoulombs (mC), respectively. The IST was predicted by age, gender, and dose (mg/kg) of sodium thiopental. Other physical and clinical variables were not associated with the IST. ConclusionThe present study demonstrated that the IST of 1-ms BP-BL ECT following sodium thiopental anesthesia in Korean patients was comparable to those reported in previous literature. The IST was associated with age, gender, and dose of sodium thiopental.
