Abstract
INTRODUCTION QT interval dispersion, which reflects the regional heterogeneity of ventricular repolarization, increases during electroconvulsive therapy (ECT). Tpeak-Tend (TpTe) is considered a new marker of the transmural dispersion of ventricular repolarization (TDR). This study aimed to evaluate the effect of remifentanil on TpTe during ECT. METHODS Forty-two patients who were scheduled to undergo ECT with American Society of Anesthesiologists physical status I or II randomly received 0.1 μg/kg remifentanil (group R: n = 21) or saline (group C: n = 21). After the induction of general anesthesia, we measured the TpTe, TpTe/QT, TpTe/QTc, TpTe/RR, TpTe/√RR and TpTe/3√RR every minute during ECT (QT: QT interval, QTc: corrected QT interval, RR: RR interval). Statistical analysis was performed using two-way analysis of variance (ANOVA). RESULTS Immediately (T0) and 1 min (T1) after electrical stimulation, the RRs (group C: T0; 654.2 ± 145.9 ms, T1; 657.3 ± 114.8 ms, group R: T0; 849.6 ± 249.3 ms, T1; 885.4 ± 213.6 ms, p < 0.05) were significantly increased, while systolic (group C: T0; 177.1 ± 35 mmHg, group R: T0; 129 ± 27.2 mmHg, p < 0.05) and diastolic blood pressures (group C: T0; 107.1 ± 22.4 mmHg, T1; 101.3 ± 23.2 mmHg, group R: T0; 75.4 ± 19.3 mmHg, T1; 80.6 ± 18.3 mmHg, p < 0.05) were significantly decreased in group R compared to group C. The TpTe/RR was significantly lower at T1 in group R compared to group C (group C: 101.5 ± 28.2, group R: 76.8 ± 21.8, p < 0.05). However, there was no significant difference in TpTe, TpTe/QT, TpTe/QTc, TpTe/√RR or TpTe/3√RR between the two groups throughout the study. CONCLUSION Pretreatment with remifentanil suppressed the increase of TpTe/RR after electrical stimulation. Our results imply that remifentanil may lead to a decrease in TDR during ECT. TRIAL REGISTRATION This trial was registered with the University Hospital Medical Information Network (registration number: UMIN000051958).

Abstract
OBJECTIVES Takotsubo cardiomyopathy (TCM) is a life-threatening complication of electroconvulsive therapy (ECT). We report the case of a 66-year-old woman who was rechallenged with ECT after ECT-induced TCM. Moreover, we have made a systematic review to assess the safety of and strategies for reinitiating ECT after TCM. METHODS We searched for published reports on ECT-induced TCM since 1990 in MEDLINE (PubMed), Scopus, Cochrane Library, ICHUSHI, and CiNii Research. RESULTS A total of 24 ECT-induced TCM cases were identified. Patients who developed ECT-induced TCM were predominantly middle-aged and older women. There was no specific trend in anesthetic agents used. Seventeen (70.8%) cases developed TCM by the third session in the acute ECT course. Eight (33.3%) cases developed ECT-induced TCM despite the use of β-blockers. Ten (41.7%) cases developed cardiogenic shock or abnormal vital signs related to cardiogenic shock. All cases recovered from TCM. Eight (33.3%) cases tried to receive ECT retrial. The duration until ECT retrial was between 3 weeks and 9 months. The most common preventive measures during ECT retrial were related to β-blockers; however, the type, dose, and route of administration of β-blockers varied. In all cases, ECT could be reperformed without TCM recurrence. CONCLUSIONS Electroconvulsive therapy-induced TCM is more likely to cause cardiogenic shock than nonperioperative cases; nevertheless, it has good prognosis. Cautious reinitiation of ECT after TCM recovery is possible. Further studies are required to determine preventive measures for ECT-induced TCM.

Abstract
OBJECTIVES Electroconvulsive therapy (ECT) is frequently associated with significant hemodynamic changes that increase myocardial oxygen demand including significant hypertension poststimulus. This raises concern about the cumulative effect of repetitive stress from ECT. Historically, various agents have been used to blunt this response and reduce hemodynamic fluctuations in these patients with varying degrees of efficacy. We hypothesized that bolus alfentanil administration timed with the ECT stimulus may reduce near-term hypertension and heart rate (HR) increases in patients undergoing ECT. METHODS A randomized, double-blind, placebo-controlled AB/BA crossover trial of 87 patients 18 years or older with mood disorders was carried out. Patients received a standardized anesthetic regimen including induction with methohexital and succinylcholine and were randomized to receive either 20 μg/kg ideal bodyweight of alfentanil or placebo 60 seconds before the ECT stimulus for the first treatment and then crossed over to the other group for the second treatment. The primary outcome was the within-individual difference in preinduction systolic blood pressure and the first systolic blood pressure after the ECT stimulus. RESULTS Eighty-seven patients completed the protocol. The primary outcome of increase in systolic blood pressure pre-ECT to post-ECT was 16.9 mm Hg less in the alfentanil group than the placebo group (95% confidence interval, -26.0 to -7.8; P < 0.001). The maximum HR was 6.5 beats per minute lower (95% confidence interval, -12.1 to -0.9; P = 0.024) when patients received alfentanil compared with placebo. CONCLUSIONS Premedication with alfentanil reduces poststimulus hypertension and increased HR in patients receiving ECT and therefore, may reduce morbidity related to this in susceptible patients.

Risk Assessment of Electroconvulsive Therapy in Clinical Routine: A 3-Year Analysis of Life-Threatening Events in More Than 3,000 Treatment Sessions. Front Psychol 2021; 12:767915. [PMID: 34887815 PMCID: PMC8650631 DOI: 10.3389/fpsyg.2021.767915] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/31/2021] [Accepted: 10/20/2021] [Indexed: 11/13/2022] Open
Abstract
Background: Extensive research has reported that electroconvulsive therapy (ECT) can be highly effective in approximately 80% of patients suffering from depression. Its clinical use is mainly limited by historical objections and the concern about unwanted adverse effects (AEs), including serious and potentially life-threatening adverse events (pLTAEs), induced either by ECT or by anesthesia. Objective risk estimation is, therefore, a decisive factor in determining an indication for ECT. Methods: This paper presents a retrospective analysis of 3-year safety protocols and patient files of 157 patients who received a total of 3,106 ECT applications in a psychiatric inpatient setting at a psychiatric community hospital. This patient group comprises 5.3% of inpatients admitted with comparable diagnoses. Adverse events were analyzed from standardized safety protocols and patient files with a focus on pLTAEs. Results: Adverse events were reported for 30 (19.1%) of the 157 participants during 39 (6.1%) of 641 hospital stays. Serious pLTAEs occurred during three electroconvulsive stimulations in three patients, who needed action through the administration of medication or mechanical respiration. No patient suffered permanent damage to health, and no patient died. The incidence of these and other AEs was independent of sex, age, and diagnosis of patients, and anesthesia medication. Minor AEs occurred more often with higher stimulus doses and an increasing number of treatments. Conclusion: The low incidence rate of 0.097% of serious pLTAEs that require medical action may allow the conclusion that ECT is a rather safe treatment when performed in a controlled setting. The beneficial risk profile of ECT performed in the standard care of psychiatric hospitals suggests a more generous indication of this treatment method. We recommend that ECT facilities collect individual safety data to allow a reliable judgment of their institutional ECT risk profile.

JOURNAL OF RESEARCH IN MEDICAL SCIENCES : THE OFFICIAL JOURNAL OF ISFAHAN UNIVERSITY OF MEDICAL SCIENCES 2021; 26:106. [PMID: 35126569 PMCID: PMC8765514 DOI: 10.4103/jrms.jrms_951_19] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/17/2020] [Revised: 04/25/2020] [Accepted: 06/02/2021] [Indexed: 06/14/2023]
Abstract
BACKGROUND Electroconvulsive therapy (ECT) is nowadays used commonly as one the most effective treatment methods in psychiatric disorders. In patients undergoing ECT, succinylcholine is usually used. In addition, cisatracurium is occasionally used on a case report basis globally. In this study, we compared the hemodynamic changes and serum potassium levels in the use of succinylcholine and cisatracurium in ECT. MATERIALS AND METHODS The current crossover clinical trial was performed on 45 patients who were candidates for ECT between 2017 and 2018. The patients were given succinylcholine or cisatracurium randomly on two separate occasions of ECT. The independent t-test and Chi square Test were used to compare the data. RESULTS Comparison of mean systolic blood pressure (P = 0.14), diastolic blood pressure (P = 0.33), and mean arterial pressure (P = 0.23) did not show any significant difference between the two groups. The induced seizure duration (P = 0.002), return of spontaneous respiratory from seizure ending (P = 0.001), and apnea duration (P = 0.01) were significantly higher in the cisatracurium group compared to the succinylcholine group. However, the frequency of tachycardia in cisatracurium group was lower than the succinylcholine group (P < 0.001). In addition, the serum potassium level had a significant difference (P < 0.001) between the two groups. CONCLUSION Using cisatracurium can be an alternative to succinylcholine during ECT since it causes less elevation in serum potassium and creates a longer duration of induced seizure, more rapid re emergence of spontaneous breathing at the end of seizure (P = 0.001), and a lower prevalence of tachycardia compared to succinylcholine (P < 0.001).

Abstract
Electroconvulsive therapy (ECT) is a definitive treatment for patients with psychiatric disorders that are severe, acute, or refractory to pharmacologic therapy. Providing anesthesia for ECT is challenging, as the effect of drugs on hemodynamics, seizure duration, comfort, and recovery must be considered. We highlight and aim to review the common anesthetics used in ECT and related evidence. While drugs such as methohexital, succinylcholine, and etomidate have been used in the past, other drugs such as dexmedetomidine, ketamine, and remifentanil may provide a more balanced anesthetic with a greater safety profile in select populations. Overall, it is essential to consider the patient’s co-morbidities and associated risks when deciding on an anesthetic drug.

Sevoflurane in electroconvulsive therapy: A systematic review and meta-analysis of randomised trials. J Psychiatr Res 2021; 141:16-25.

Abstract
Sevoflurane is the most commonly used inhaled anaesthetic in electroconvulsive therapy (ECT). The objective of this study was to provide an up-to-date and comprehensive review on how the use of sevoflurane affects seizure adequacy (seizure duration and postictal suppression index [PSI]) and circulatory dynamics in ECT. We performed a meta-analysis of RCTs that investigated seizure adequacy and circulatory dynamics in patients treated with ECT using sevoflurane (sevoflurane group) and intravenous anaesthetics (non-sevoflurane group). A total of 12 RCTs (377 patients and 1339 ECT sessions) were included. Sevoflurane significantly decreased the electroencephalogram (EEG) seizure durations in comparison with intravenous anaesthetics, whereas no significant difference was observed in PSI (EEG: 9 studies, standardized mean difference (SMD) = 0.74, 95% confidence interval (CI) = -1.11 to -0.38, p = 0.0002; PSI: 4 studies, SMD = -0.06, CI -0.13 to 0.25, p = 0.59). The use of sevoflurane in ECT significantly increased heart rate (HR) compared with intravenous anaesthetics (9 studies, SMD = 0.31, CI 012-0.51, p = 0.004). In the pre-planned subgroup analysis, sevoflurane significantly reduced seizure duration compared with other types of anaesthetics, including propofol, barbiturates and ketamine. Furthermore, it was found that the risk of adverse events in ECT with sevoflurane were not significantly different from intravenous anaesthetics (6 studies, risk ratio = 1.33, CI 0.95-1.86, p = 0.09), with agitaion being the most common adverse effects. The results of our study suggest that using sevoflurane for ECT significantly reduces seizure duration, increases maximum HR and brings about no difference in the adverse event risk compared with those using intravenous anaesthetics for ECT. Therefore, there may not be compelling evidence favouring sevoflurane use for ECT, except in cases where intravenous access is difficult.

Abstract
AbstractElectroconvulsive therapy (ECT) is one of the most successful treatment techniques employed in psychiatric practice. ECT is usually administered as a last resort to a patient who fails to respond to medical management or on an urgent basis as a life-saving procedure when immediate response is desired. It is performed under general anesthesia and is often associated with autonomic changes. All attempts should be made to minimize the resulting hemodynamic disturbances in all the patients using various pharmacological methods. Anesthesiologists providing anesthesia for ECT frequently encounter patients with diverse risk factors. Concurrent cardiovascular, neurological, respiratory, and endocrine disorders may require modification of anesthetic technique. It is ideal to optimize patients before ECT. In this review, the authors discuss the optimization, management, and modification of anesthesia care for patients with various cardiac, neurological, respiratory, and endocrine disorders presenting for ECT to improve the safety of the procedure. It is not infrequent that an anesthesiologist also plays an important role in inducing a seizure. Proconvulsants such as caffeine, adjuvants like opioids, hyperventilation, and appropriate choice of anesthetic agent for induction such as etomidate or ketamine can help. The use of BIS monitoring to guide the timing of electric stimulation is also elaborated in this review.

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
Cerebral amyloid angiopathy (CAA) is a condition characterised by accumulation of amyloid beta protein (Aβ) in the wall of cerebral blood vessels which increases the risk of intracranial haemorrhage and contributes to cognitive impairment. We describe the case of a man around the age of 70 with ‘probable’ CAA according to the modified Boston criteria and severe depression whose depression was treated successfully with electroconvulsive therapy (ECT). To the best of our knowledge, there are no earlier published reports of ECT in a patient with CAA. We briefly discuss possible safety measures for these patients, the impact of ECT on cognition in CAA and a possible influence of ECT on Aβ clearance.

Abstract
OBJECTIVE Electroconvulsive therapy (ECT) is indicated for various psychiatric situations that are difficult to manage otherwise and may be regarded as a last resort but seizure induction is sometimes difficult, resulting in inadequate trials and futile outcomes. METHOD We report on a 72-year-old female patient with bipolar depression whose seizure induction with ECT was challenging but the use of flumazenil was deemed effective to obtain remission in the end. We also provide a literature review on this topic. RESULTS Seizure induction was managed with the use of flumazenil, a selective GABA-A receptor antagonist to neutralize the effects of benzodiazepine hypnotics, together with decreasing the amount of anesthesia, increasing the pulse width, and adding chlorpromazine. A PubMed search with keywords of flumazenil and ECT yielded only 14 hits (December 2020) and found some indication that flumazenil might be of use for this purpose even in the absence of benzodiazepines, although evidence base has remained very limited. CONCLUSIONS Flumazenil, an antidote of benzodiazepines, may be effective regardless of whether benzodiazepines are in use. Because inefficient ECT is clinically problematic, more studies are necessary to investigate the effectiveness of flumazenil for successful seizure induction with ECT.

Abstract
BACKGROUND Non-invasive brain stimulation (NIBS) techniques have emerged as a promising tool for understanding and treating psychiatric disorders, necessitating a caution in terms of interpreting research results. OBJECTIVE This study aimed at systematically evaluating a representative sample of research conducted using NIBS interventions in neuro-psychiatric conditions, and assessing the power these studies achieved, given their sample sizes. METHODS A database search was conducted with defined keyword combinations. Using reported summary effects of the meta-analyses as estimate of the true effects, we calculated achieved power of each individual study to detect the effect indicated by the corresponding meta-analysis. RESULTS Findings suggest that mean and median powers in the field of NIBS were 0.50, with a mode at 0.83 (range 0.05-1.00). When analysed separately, the median powers were 0.27 for tDCS, 0.70 for TMS and 0.97 for ECT. These studies had a mean total sample size of 22.2 ± 24.9 subjects and the median reported effect size across all studies was 0.61. CONCLUSION According to our findings, studies conducted in NIBS miss around 50% of true positive results. Further, it appears that most of the researchers in this field chase statistical significance with small sample sizes, thus compromising the quality of their conclusions.

Abstract
The use of remifentanil in clinical practice offers several advantages and it is used for a wide range of procedures, ranging from day-surgery anesthesia to more complex procedures. Nonetheless, remifentanil has been consistently linked with development of opioid-induced hyperalgesia (OIH), which is described as a paradoxical increase in sensitivity to painful stimuli that develops after exposure to opioid treatment. The development of OIH may cause several issues, delaying recovery after surgery and preventing timely patient's discharge. Moreover, it causes patient's discomfort with higher pain scores, greater use of analgesics, and associated side effects. Remifentanil is the opioid most convincingly associated with OIH, and hereby we provide a review of remifentanil-induced hyperalgesia, describing both the underlying mechanisms involved and the available studies investigating experimental and clinical pharmacologic approaches aiming at reducing its incidence and degree.

Abstract
OBJECTIVE The aim of this study was to investigate how the combined use of dexmedetomidine with intravenous anesthetics influences seizure duration and circulatory dynamics in electroconvulsive therapy (ECT). METHODS A literature search was performed to identify studies that evaluated the effect of dexmedetomidine on motor- or electroencephalogram (EEG)-based seizure durations and maximum mean arterial pressure (MAP) and heart rate (HR) after ECT. Moreover, recovery time and post-ECT agitation were evaluated. RESULTS Six studies enrolling 166 patients in 706 ECT sessions were included. There was no significant difference in motor or EEG seizure duration between dexmedetomidine and nondexmedetomidine groups [motor: 6 studies; mean difference (MD), 1.62; 95% confidence interval (CI), -2.24 to 5.49; P = 0.41; EEG: 3 studies; MD, 2.34; 95% CI, -6.03 to 10.71; P = 0.58]. Both maximum MAP and HR after ECT were significantly reduced in the dexmedetomidine group (MAP: 6 studies; MD, -4.83; 95% CI, -8.43 to -1.22; P = 0.009; HR: 6 studies; MD, -6.68; 95% CI, -10.74 to -2.62; P = 0.001). Moreover, the addition of dexmedetomidine did not significantly prolong recovery time when the reduced-dose propofol was used (4 studies; MD, 63.27; 95% CI, -15.41 to 141.96; P = 0.12). CONCLUSIONS The use of dexmedetomidine in ECT did not interfere with motor and EEG seizure durations but could reduce maximum MAP and HR after ECT. Besides, the addition of dexmedetomidine in ECT did not prolong recovery time when reduced-dose propofol was used. It might be worthwhile for patients to receive dexmedetomidine before the induction of anesthesia in ECT.
