J Affect Disord 2024:S0165-0327(24)01530-1. [PMID: 39265871 DOI: 10.1016/j.jad.2024.09.038] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/04/2024] [Revised: 09/05/2024] [Accepted: 09/08/2024] [Indexed: 09/14/2024]
Abstract
BACKGROUND Electroconvulsive therapy (ECT) is a commonly used alternative for treatment-resistant depression (TRD). Although esketamine has a rapid pharmacological antidepressant action, it has not been studied as an ECT anesthetic. The objective of this study was to compare the efficacy and safety of esketamine with propofol when both are used as ECT anesthetic agents. METHODS Forty patients with TRD were assigned to one of two arms in a double-blind, randomized controlled trial: esketamine or propofol anesthesia for a series of eight ECT sessions. Using a non-inferiority design, the primary outcome was the reduction in HAMD-17 depressive symptoms. The other outcomes were: rates of response and remission, anxiety, suicidal ideation, cognitive function, and adverse events. These were compared in an intention-to-treat analysis. RESULTS Esketamine-ECT was non-inferior to propofol-ECT for reducing TRD symptoms after 8 sessions (adjusted Δ = 2.0, 95 % CI: -1.2-5.1). Compared to propofol-ECT, esketamine-ECT also had higher depression response (80 % vs. 70 %; p = .06) and remission (65 % vs. 55 %; p = .11) rates but non-inferiority was not established. In four components of cognitive function (speed of processing, working memory, visual learning, and verbal learning) esketamine-ECT was non-inferior to propofol-ECT. The results for anxiety, suicidal ideation, and adverse events (all p's > 0.05) were inconclusive. CONCLUSION Esketamine was non-inferior to propofol when both are used as anesthetics for TRD patients undergoing ECT. Replication studies with larger samples are needed to examine the inconclusive results. REGISTRATION NUMBER ChiCTR2000033715.

Abstract
OBJECTIVE Studies have demonstrated the efficacy of injectable caffeine as an augmentation method in electroconvulsive therapy (ECT). This study investigated whether orally administered caffeine increases seizure duration during ECT. METHODS Medical records of 40 patients treated with a series of ECT were retrospectively analyzed. Patients whose electroencephalogram (EEG) seizure duration had dropped<30 s, or motor seizure duration<15 s were included. They subsequently received oral caffeine (0.2 g) before ECT sessions. Primary outcomes were EEG seizure duration and motor seizure duration, compared with those from the last pre-caffeine session (baseline) and the first five caffeine-augmented sessions. The mental state was assessed with the Global Assessment of Functioning (GAF). In addition, data on maximum heart rate, maximal arterial pressure, and adverse effects were collected. RESULTS The EEG seizure duration increased by 14.9 s (52%) on average between baseline and the first caffeine-augmented session. The increased length remained widely stable over the subsequent ECT sessions. EEG seizure duration was>30 s in more than 80% of sessions. A statistically significant increase in motor seizure duration appeared only in the 2nd and 3rd of five sessions with augmentation. Oral caffeine pretreatment was overall well tolerated. The percentage of patients with at least serious mental impairment (GAF score≤50) dropped from 77.5 to 15%. CONCLUSIONS Results suggest the utility of oral caffeine (0.2 g) to increase ECT-induced seizures in patients with durations below clinically significant thresholds.

Psychiatry Investig 2022; 19:824-831. [PMID: 36327962 PMCID: PMC9633168 DOI: 10.30773/pi.2022.0123] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/12/2022] [Accepted: 08/07/2022] [Indexed: 11/27/2022] Open
Abstract
OBJECTIVE We compared retrospectively the seizure variables of electroconvulsive therapy (ECT) patients after administration of rocuronium-sugammadex or succinylcholine as a muscle relaxant with propofol anesthesia. METHODS The sample comprised 134 ECT patients. The mean age was 33.6±10.48 years. Anesthesia induction was provided with propofol one mg kg-intravenously (IV) followed by succinylcholine 0.5 mg kg-1 IV (n=68) (Group S) or rocuronium 0.3 mg kg-1 IV (n=66) (Group R). For patients who were given rocuronium, reversal of the residual neuromuscular block was accomplished with sugammadex (1.5 mg kg-1 IV). First session seizure variables were compared between the two groups. We also presented the clinical outcome with Clinical Global Impression-Improvement (CGI-I) and overall adverse effects. RESULTS EEG seizure durations in Group R (55.09±36.11 s) and Group S (47.00±26.33 s) were comparable and were not significantly different (p=0.432). The clinical efficacy of ECT measured by CGI-I in both groups was comparable (p=0.075). There were no major complications or death during or after ECT. CONCLUSION The results of this study show that the use of rocuronium-sugammadex as a neuromuscular blocker instead of succinylcholine during ECT with propofol anesthesia produces similar results in terms of seizure variables and clinical outcomes.

Abstract
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.

Abstract
BACKGROUND Seizure duration has long been measured as a potential marker of ECT treatment efficacy, with concern that short seizures may be clinically ineffective. Relatively small studies have documented a trend towards shorter seizures during acute course ECT, but data from large cohorts would help provide normative data on seizure duration changes during treatment. OBJECTIVE This study analyzes the effects of age, sex, ECT dose, and treatment number on the duration of electrographic seizures during acute course ECT in a large single-center cohort. METHODS A single-center retrospective chart review was conducted of adult patients receiving a first course of ECT from 2000 to 2017 at a large freestanding psychiatric hospital. RESULTS 3648 patients met inclusion criteria, receiving 32,879 acute course ECT treatments. There was a shortening of mean ECT seizure duration over the acute course, with the greatest decrease in duration over the first 3 treatments but continuing decreases over the entire acute course. Older age, higher ECT dose, and increasing treatment number were all associated with shorter seizures, while sex was not significantly associated. Increasing treatment dose was associated with shorter seizures relative to no dose increase, with those patients receiving the highest cumulative doses also having the shortest cumulative seizure time. CONCLUSIONS Among patients undergoing acute-course ECT treatment, seizure duration decreased over the treatment course, and increases in applied electrical charge were associated with shorter seizures.

Abstract
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.

Abstract
OBJECTIVES Eliciting a generalized seizure is essential to electroconvulsive therapy (ECT), but there is still a need to understand how patient and session variables interact to generate a seizure of adequate quality. Here, we investigate factors associated with motor seizure length as a measure of quality in a large database of patients who underwent ECT. METHODS This is a retrospective cohort including data from all adult inpatients who underwent ECT at a university hospital in Brazil from 2009 to 2015. We used linear mixed models to investigate the effects of patient, session, and medication on seizure length. RESULTS Session information was available for 387 patients, a total of 3544 sessions and 4167 individual stimulations. Multiple stimulations were necessary in 12.4% of sessions. Median seizure length was 30 seconds. Seizure length was directly correlated with stimulus dosage and inversely correlated with the session number, patient age, prescription of anticonvulsants in the day before and β-blockers during the session, and the thiopental dose. Use of benzodiazepines was not associated with a shorter seizure duration, irrespective of dose. CONCLUSIONS We demonstrate here how motor seizure length evolves during a course of ECT. With a large number of sessions, we are able to integrate a host of factors in a prediction model. Seizure quality was influenced by a number of the studied factors, many of which are potentially modifiable and could be assessed before initiating and handled during treatment.

Abstract
Electroconvulsive therapy (ECT) is an effective treatment for severe psychiatric disorders. Patients referred to ECT are often taking multiple medications, many of which can potentially affect the safety and efficacy of their course of ECT. This review evaluates the impact of a variety of psychotropic medications often used in conjunction with ECT and examines strategies to optimize their management. The review encompasses mood stabilizers, antidepressants, benzodiazepines, antiepileptics, antipsychotics, and other commonly used psychotropics.

Abstract
BACKGROUND The aim of this study is to determine the efficacy of preemptive analgesia with paracetamol and ibuprofen to reduce the intensity and incidence of headache and myalgia after electroconvulsive therapy (ECT). METHODS Sixty patients with major depression who were treated with ECT were randomized to receive ECT 3 times a week. The first 3 sessions were included in the study. The patients were divided into 3 groups; Group C (Control, Saline, n = 20), Group P (Paracetamol, n = 20), and Group I (Ibuprofen, n = 20). Demographics, duration of seizure, visual analog scale (VAS) for headache and myalgia and nausea, vomiting and pruritus were evaluated at postoperative 24 hours period. RESULTS Duration of seizure after ECT was similar in all groups (P = .148). In the study, heart rate and mean arterial pressure were found to be some changes in some of the sessions. There were no significant differences in any comparison for all groups in all sessions regarding VAS scores for headache and myalgia. Incidence of headache and myalgia in Group I was lower than the other groups (P = .233, P = .011, respectively). But, there was no significant difference between the other groups. There was no significant difference in vomiting, intergroups, and intragroup. CONCLUSIONS The findings of our study indicate that pain intensity of headache and myalgia did not show a significant change between groups and within groups. While pain intensity of myalgia between the groups reached no statistical significance, ibuprofen was significantly lowered the incidence of myalgia at postoperative 24 hours period.

Abstract
BACKGROUND Electroconvulsive therapy (ECT) is one of the most effective treatments for major depressive disorder (MDD), especially in cases of treatment-resistant MDD. Because of their pharmacological profiles, benzodiazepines (BZDs) are suspected to decrease the efficacy of ECT. This study investigated the effect of BZDs on ECT-induced clinical outcomes and ECT course parameters in patients with MDD. METHOD The impact of BZDs on severity of depression (Montgomery-Asberg Depression Rating Scale scores) and on ECT course parameters (seizure threshold, clinical and electroencephalographic seizure duration) was investigated in 70 patients with MDD who received an ECT course using dose-titration method (22 received concomitant BZDs). RESULTS Lower remission rates (52.0%) and smaller decreases in Montgomery-Asberg Depression Rating Scale scores were observed in the non-BZD group than in the BZD group (81.2%, P = 0.02). There were no significant differences between the 2 groups regarding seizure duration and seizure threshold. LIMITATIONS This was a retrospective study. Impact of BZDs on anxiety and cognition was not assessed. CONCLUSIONS Benzodiazepines increased the clinical efficacy of ECT when delivered using dose-titration method and bitemporal stimulation. Further studied are needed to understand the interaction between BZDs and ECT on clinical outcomes.

Abstract
OBJECTIVE The 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. METHODS Among 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. RESULTS The 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. CONCLUSION The 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.
