Abstract
Thiopental sodium (TPTS) is a barbiturate general anesthetic, while its effects on hypoxia/reoxygenation (H/R)-induced injury are still unclear. This study aimed to investigate whether TPTS exerts protective effects against the H/R-induced osteoblast cell injury and explore the underlying mechanisms. Osteoblast cell injury model was induced by the H/R condition, which was treated with or without TPTS. Cell viability and lactate dehydrogenase (LDH) release were determined by the corresponding commercial kits. The levels of oxidative stress were determined in the experimental groups. Cell apoptosis and Caspase-3 activities were determined by propidium iodide staining and substrate-based assay, respectively. Western blotting and qRT-PCR were performed to measure the mRNA and protein levels, respectively. Treatment with TPTS was able to increase cell viability and reduce LDH release in H/R-induced osteoblasts. Additionally, TPTS regulated oxidative stress in H/R-induced osteoblasts by suppressing malondialdehyde (MDA) and reactive oxygen species (ROS) as well as boosting superoxide dismutase (SOD). TPTS was able to suppress cell apoptosis by suppressing Caspase-3 activity and cleavage. TPTS exerted protective effects against cell injury and apoptosis induced by the H/R conditions, which were associated with its regulation of Akt signaling. Moreover, TPTS induced osteoblast differentiation under the H/R condition. In summary, TPTS attenuates H/R-induced injury in osteoblasts by regulating AKT signaling.

Abstract
Counselling and medication are often thought of as the only interventions for psychiatric disorders, but electroconvulsive therapy (ECT) has also been applied in clinical practice for over 80 years. ECT refers to the application of an electric stimulus through the patient’s scalp to treat psychiatric disorders such as treatment-resistant depression, catatonia, and schizophrenia. It is a safe, effective, and evidence-based therapy performed under general anesthesia with muscle relaxation. An appropriate level of anesthesia is essential for safe and successful ECT; however, little is known about this because of the limited interest from anesthesiologists. As the incidence of ECT increases, more anesthesiologists will be required to better understand the physiological changes, complications, and pharmacological actions of anesthetics and adjuvant drugs. Therefore, this review focuses on the fundamental physiological changes, management, and pharmacological actions associated with various drugs, such as anesthetics and neuromuscular blocking agents, as well as the comorbidities, indications, contraindications, and complications of using these agents as part of an ECT procedure through a literature review and our own experiences.

Abstract
ABSTRACT Electroconvulsive therapy (ECT) remains stigmatized in the broader medical community because of misunderstandings about treatment procedures, mortality rates, and cardiovascular complications. Electroconvulsive therapy causes periprocedural hemodynamic variability because of the surges in parasympathetic and sympathetic nervous systems after the administration of the electrical charge. Patients experience an increase in cardiac workload, which is potentially dangerous for patients with preexisting heart disease. Several findings suggest that cardiac complications occur most frequently in patients with underlying cardiovascular disease. We describe the cardiovascular complications that may result from ECT treatment and offer insight on how to mitigate these concerns if they occur. PubMed was queried using terms "electroconvulsive therapy" and "cardiovascular adverse effects." A table is provided with the common cardiovascular side effects of ECT and the most recent evidence-based treatment strategies to manage them. Generally, ECT is a safe procedure in which complications are minor and manageable. Most major complications caused by ECT are related to the cardiovascular system; however, with an appropriate pre-ECT evaluation and a comprehensive multidisciplinary team approach, the cardiovascular complications can be well managed and minimized. Providing proper cardiac clearance can prevent cardiac complications and provide timely care to treatment-resistant populations who are at risk for excessive morbidity and suicide.

Abstract
The complicated history of modified electroconvulsive therapy (ECT) started back before anesthesia was incorporated when unmodified electroconvulsive therapy was not considered humane. When anesthesiologists started working with psychiatrists, ECT gradually regained acceptance by decreasing the obstacles inherent to this therapy despite the complexities of the anesthetics. However, the sociopolitical and medicolegal factors negatively impacted the use of modified ECT leading to a period of time when it was banned from use in the United States. Fortunately, as advances in anesthesia and technology continued to develop, anesthesiologists helped ECT regain widespread usage improving the safety profile, cost effectiveness, quicker onset of seizures, and ease of control despite its stained past. This allowed more accessibility, especially for high-risk medical patients, to a relatively safe and effective treatment for psychiatric diseases.

Abstract
Electroconvulsive therapy (ECT) was first experienced in 1938 and had been conducting without anesthesia for 30 years. In this study, the most common indication for ECT was mood disorder (major depressive disorder and bipolar I disorder). We introduce a patient with a history of COVID-19 and suicide who required emergency ECT. Electroconvulsive therapy can be life-saving in patients with suicide history or catatonic schizophrenia. Health workers are at the front line of the COVID-19 outbreak control and must follow health instructions. Aerosol-producing procedures such as suction in anesthesia for ECT may facilitate the transmission of infectious diseases such as COVID-19. When performing aerosol-producing procedures during the pandemic of novel coronavirus, every patient should be considered suspicious.

Abstract
BACKGROUND Few cases of asystole or severe bradycardia occurring after the termination of seizure in the third phase with the dominance of parasympathetic nervous system activity during electroconvulsive therapy (ECT) have been reported. We describe a case of severe bradycardia occurring at the termination of seizure. CASE PRESENTATION The patient had been diagnosed with bipolar disorder more than 9 years earlier. No adverse hemodynamic events had been observed in over 100 sessions of ECT performed during a 9-year period. ECT was usually induced by propofol and suxamethonium. On this ECT, the heart rate gradually decreased before seizure termination, and severe bradycardia (5-6 beats/min) was identified lasting 15-20 s. Atropine administration immediately before electrical stimulus prevented any further bradycardia during the next session of ECT. CONCLUSIONS This case report indicates that attention should be paid to adverse cardiac events related to autonomic nerve activity even before such events occur during ECT.

Abstract
BACKGROUND The effects of sedative and anesthetic agents on sympathetic nerve activity (SNA) are poorly understood. OBJECTIVE The purpose of this study was to determine the effects of commonly used sedative and anesthetic agents on SNA in ambulatory dogs and humans. METHODS We implanted radiotransmitters in 6 dogs to record stellate ganglion nerve activity (SGNA), subcutaneous nerve activity (ScNA), and blood pressure (BP). After recovery, we injected dexmedetomidine (3 μg/kg), morphine (0.1 mg/kg), hydromorphone (0.05 mg/kg), and midazolam (0.1 mg/kg) on different days. We also studied 12 human patients (10 male; age 68.0 ± 9.1 years old) undergoing cardioversion for atrial fibrillation with propofol (0.77 ± 0.18 mg/kg) or methohexital (0.65 mg/kg) anesthesia. Skin sympathetic nerve activity (SKNA) and electrocardiogram were recorded during the study. RESULTS SGNA and ScNA were significantly suppressed immediately after administration of dexmedetomidine (P = .000 and P = .000, respectively), morphine (P = .011 and P = .014, respectively), and hydromorphone (P = .000 and P = .012, respectively), along with decreased BP and heart rate (HR) (P <.001 for each). Midazolam had no significant effect on SGNA and ScNA (P = .248 and P = .149, respectively) but increased HR (P = .015) and decreased BP (P = .004) in ambulatory dogs. In patients undergoing cardioversion, bolus propofol administration significantly suppressed SKNA (from 1.11 ± 0.25 μV to 0.77 ± 0.15 μV; P = .001), and the effects lasted for at least 10 minutes after the final cardioversion shock. Methohexital decreased chest SKNA from 1.59 ± 0.45 μV to 1.22 ± 0.58 μV (P = .000) and arm SKNA from 0.76 ± 0.43 μV to 0.55 ± 0.07 μV (P = .001). The effects lasted for at least 10 minutes after the cardioversion shock. CONCLUSION Propofol, methohexital, dexmedetomidine, morphine, and hydromorphone suppressed, but midazolam had no significant effects on, SNA.

Abstract
Proper planning and communication between psychiatry and anesthesiology teams is vital to conferring the greatest therapeutic benefit to children presenting for electroconvulsive therapy while minimizing risk. Anesthesia for the child undergoing electroconvulsive therapy should ideally provide deep hypnosis, ensure muscle relaxation to reduce injury, have minimal effect on seizure dynamics, and allow for rapid recovery to baseline neurologic and cardiopulmonary status. Unique factors for pediatric electroconvulsive therapy include the potential need for preoperative anxiolytic and inhalational induction of anesthesia, which must be weighed against the detrimental effects of anesthetic agents on the evoked seizure quality required for a successful treatment.

Abstract
Electroconvulsive therapy is being used more frequently in the treatment of many chronic and acute psychiatric illnesses in children. The most common psychiatric indications for pediatric electroconvulsive therapy are refractory depression, bipolar disorder, schizophrenia, catatonia, and autism. In addition, a relatively new indication is the treatment of pediatric refractory status epilepticus. The anesthesiologist may be called upon to assist in the care of this challenging and vulnerable patient population. Unique factors for pediatric electroconvulsive therapy include the potential need for preoperative anxiolytic and inhalational induction of anesthesia, which must be weighed against the detrimental effects of anesthetic agents on the evoked seizure quality required for a successful treatment. Dexmedetomidine is likely the most appropriate preoperative anxiolytic as oral benzodiazepines are relatively contraindicated. Methohexital, though becoming less available at many institutions, remains the gold standard for induction of anesthesia for pediatric electroconvulsive therapy though ketamine, propofol, and sevoflurane are becoming increasingly viable options. Proper planning and communication between the multidisciplinary teams involved in the care of children presenting for electroconvulsive therapy treatments is vital to mitigating risks and achieving the greatest therapeutic benefit.

Abstract
Seizures are accompanied by cardiovascular changes that are a major cause of sudden unexpected death in epilepsy (SUDEP). Seizures activate inflammatory responses in the cardiovascular nuclei of the medulla oblongata and increase neuronal excitability. Pituitary adenylate cyclase-activating polypeptide (PACAP) is a neuropeptide with autocrine and paracrine neuroprotective properties. Microglia are key players in inflammatory responses in the CNS. We sought to determine whether PACAP and microglia mitigate the adverse effects of seizure on cardiovascular function in a rat model of temporal lobe epilepsy. Kainic acid (KA)-induced seizures increased splanchnic sympathetic nerve activity by 97%, accompanied by increase in heart rate (HR) but not blood pressure (BP). Intrathecal infusion of the PACAP antagonist PACAP(6-38) or the microglia antagonists minocycline and doxycycline augmented sympathetic responses to KA-induced seizures. PACAP(6-38) caused a 161% increase, whereas minocycline and doxycycline caused a 225% and 215% increase, respectively. In intrathecal PACAP-antagonist-treated rats, both BP and HR increased, whereas after treatment with microglial antagonists, only BP was significantly increased compared with control. Our findings support the idea that PACAP and its action on microglia at the level of the spinal cord elicit cardioprotective effects during seizure. However, intrathecal PACAP did not show additive effects, suggesting that the agonist effect was at maximum. The protective effect of microglia may occur by adoption of an M2 phenotype and expression of factors such as TGF-β and IL-10 that promote neuronal quiescence. In summary, therapeutic interventions targeting PACAP and microglia could be a promising strategy for preventing SUDEP.

Abstract
BACKGROUND Depression is a common mental disorder. It affects millions of people worldwide and is considered by the World Health Organization (WHO) to be one of the leading causes of disability. Electroconvulsive therapy (ECT) is a well-established treatment for severe depression. Intravenous anaesthetic medication is used to minimize subjective unpleasantness and adverse side effects of the induced tonic-clonic seizure. The influence of different anaesthetic medications on the successful reduction of depressive symptoms and adverse effects is unclear. OBJECTIVES This review evaluated the effects of different regimens of intravenous sedatives and hypnotics on anti-depression efficacy, recovery and seizure duration in depressed adults undergoing ECT. SEARCH METHODS We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (2012, Issue 12); MEDLINE via Ovid SP (from 1966 to 31 December 2012); and EMBASE via Ovid SP (from 1966 to 31 December 2012). We handsearched related journals and applied no language restrictions. SELECTION CRITERIA We included randomized controlled trials (RCTs) and cross-over trials evaluating the effects of different intravenous sedatives and hypnotics for ECT. We excluded studies and trials using placebo or inhalational anaesthetics and studies that used no anaesthetic. DATA COLLECTION AND ANALYSIS Two review authors independently assessed trial quality and extracted data. When possible, data were pooled and risk ratios (RRs) and mean differences (MDs), each with 95% confidence intervals (CIs), were computed using the Cochrane Review Manager statistical package (RevMan). MAIN RESULTS We included in the review 18 RCTs (599 participants; published between 1994 and 2012). Most of the included trials were at high risk of bias.We analysed the results of studies comparing six different intravenous anaesthetics.Only a few studies comparing propofol with methohexital (four studies) and with thiopental (three studies) could be pooled.No difference was noted in the reduction of depression scores observed in participants treated with propofol compared with methohexital (low-quality evidence). These four studies were not designed to detect differences in depression scores.The duration of electroencephalograph (EEG) and of motor seizures was shorter in the propofol group compared with the methohexital group (low-quality evidence). No difference was seen in EEG seizure duration when propofol was compared with thiopental (low-quality evidence).Time to recovery (following commands) was longer among participants after anaesthesia with thiopental compared with propofol (low-quality evidence).For the remaining comparisons of anaesthetics, only single studies or insufficient data were available. Adverse events were inadequately reported in eligible trials, and none of the included trials reported anaesthesia-related mortality. AUTHORS' CONCLUSIONS Most of the included studies were at high risk of bias, and the quality of evidence was generally low. The studies were not designed to detect clinically relevant differences in depression scores. Anaesthetic agents should be chosen on the basis of adverse effect profile, emergence and how these medications affect seizure duration. If it is difficult to elicit an adequately long seizure, methohexital may be superior to propofol (low-quality evidence). If a patient is slow to recover from anaesthesia, propofol may allow a faster time to follow commands than thiopental (low-quality evidence). A factor of clinical concern that was not addressed by any study was adrenal suppression from etomidate. Optimal dosages of intravenous sedatives or hypnotics have not yet been determined.Larger well-designed randomized studies are needed to determine which intravenous anaesthetic medication leads to the greatest improvement in depression scores with minimal adverse effects.

Abstract
In electroconvulsive therapy (ECT), the use of anesthetics without relevant anticonvulsant properties such as ketamine and etomidate may be favorable for seizure quality. Since there is a relative paucity of studies devoted to this issue, our aim was to compare different anesthetics for ECT regarding their impact on seizure quality and different seizure parameters. We retrospectively compared ketamine (n = 912 anesthesias), etomidate (n = 227 anesthesias), thiopental (n = 2,751 anesthesias), and propofol (n = 42 anesthesias) on their influence on general seizure quality and different seizure parameters by multivariate repeated measurement regression analyses. The use of ketamine and etomidate as anesthetics led to seizures that were overall higher in quality and also longer in motor seizure activity when compared to anesthesia with thiopental and propofol. Ketamine was most favorable concerning central inhibitory potential that was indirectly quantified by concordance and postictal suppression. The worst seizure quality was observed with propofol anesthesia; further, this substance had a negative impact on autonomic activation and seizure duration. Based on the data of this retrospective study, the use of ketamine or etomidate as anesthetic in ECT might be advantageous due to the induction of high-quality seizures.

Abstract
Electroconvulsive therapy is a well-established form of treatment for a broad spectrum of severe psychiatric disorders. The treatment, in which a generalized epileptic seizure is provoked by electrical stimulation of the brain, is performed with the patient under anesthesia and muscle relaxation. Therefore, sufficient knowledge of the physiological and pharmacological characteristics is an essential requirement for safe anesthesia. The following review is intended to provide some new aspects of the procedure and management of anesthesia.

Abstract
Objectives: To compare propofol and thiopental as anesthetic agents for electroconvulsive therapy (ECT) with respect to seizure duration, stimulus charge, and clinical effects. Materials and Methods: Randomized, blinded study of 28 patients of depression treated with bilateral ECT. In group P (n = 14), sedation was achieved with propofol 1.5 mg/kg, whereas in group T (n = 14), it was achieved with thiopentone 3 mg/ kg IV. Succinylcholine 0.4 mg/kg intravenous was given in all patients as for neuromuscular blockade. Results: The mean seizure duration of the patients in the thiopental group was 83 ± 34.43 seconds vs. 94.45 ± 21.37 seconds in the propofol group (P < 0.01). The energy delivered per treatment was 10.88 ± 4.78 J in the thiopental group vs. 12.20 ± 4.53 J in the propofol group (P < 0.05). Number of ECTs required were significantly higher in propofol group (9.71 ± 2.87) as compared to thiopental group (5.86 ± 0.36) P < 0.0001. No significant difference in duration of hospitalization was seen in both groups. The mean score on Mini-Mental State Examination (MMSE) was 29.14 in the thiopental group vs. 29.57 in the propofol group (P > 0.05). The mean score on Beck Depression Inventory (BDI) was 7.14 in the thiopental group vs. 3.29 in the propofol group (P < 0.05). Conclusions: Propofol significantly increases number of ECT required to treat although the patients received higher electrical charge and had longer seizure duration. BDI scores suggest this resulted in better outcome. Results, however, might be confounded by the differences in pharmacological treatment in the groups.

Abstract
Citosol (thiamylal sodium) is one of generally used anesthetic–sedative agents for clinical patients, and it has not been reported to show induction of cytotoxic effects in cancer cells, especially in mice leukemia RAW 264.7 cells in vitro. In the present study, we investigated the cytotoxic effects of citosol on mice leukemic RAW 264.7 cells, including the effects on protein and gene expression levels which are determined by Western blotting and DNA microarray methods, respectively. Results indicated that citosol induced cell morphological changes, cytotoxic effect, and induction of apoptosis in RAW 264.7 cells. Western blotting analysis demonstrated that citosol promoted the levels of Fas, cytochrome c, caspase 9 and 3 active form and Bax levels, but it suppressed Bcl-xl protein level that may lead to apoptotic death in RAW 264.7 cells. Furthermore, DNA microarray assay indicated that citosol significantly promoted the expression of 5 genes (Gm4884, Gm10883, Lce1c, Lrg1, and LOC100045878) and significantly inhibited the expression of 24 genes (Gm10679, Zfp617, LOC621831, Gm5929, Snord116, Gm3994, LOC380994, Gm5592, LOC380994, LOC280487, Gm4638, Tex24, A530064D06Rik, BC094916, EG668725, Gm189, Hist2h3c2, Gm8020, Snord115, Gm3079, Olfr198, Tdh, Snord115, and Olfr1249). Based on these observations, citosol induced cell apoptosis and influenced gene expression in mice leukemia RAW 264.7 cells in vitro.

Abstract
OBJECTIVES Rapid parasympathetic and sympathetic hemodynamic effects during electroconvulsive therapy (ECT) may pose vulnerable patients to significant risk for cardiovascular complications. Here, we evaluated the clinical feasibility of noninvasive beat-to-beat arterial blood pressure (BP) measurements in patients undergoing ECT. METHODS Beat-to-beat hemodynamic effects were measured with a noninvasive BP monitor in 24 individual patients undergoing ECT during general anesthesia. Heart rate, systolic (SBP), and diastolic BP (DBP) as well as cardiac output (CO) were measured continuously. A significant increase in pulse rate and/or BP was treated with intermittent administration of esmolol and ketanserin. Data are presented as mean ± SD. RESULTS The ECT stimulus induced a transient drop in BP and pulse rate, followed by a sharp rise in both parameters. The parasympathetic phase lasted 17 ± 9 seconds and was characterized by a drop in heart rate from 89 ± 15 to 42 ± 24 beats per minute, in SBP from 143 ± 22 to 91 ± 31 mm Hg, in DBP from 82 ± 13 to 54 ± 22 mm Hg, and in CO from 5.7 ± 2.3 to 1.4 ± 1.0 L/min, respectively. During the subsequent sympathetic phase, the heart rate increased to 125 ± 26 beats per minute, the SBP to 192 ± 33 mm Hg, the DBP to 113 ± 21 mm Hg, and the CO to 7.4 ± 4.3 L/min. The time interval between the lowest and highest SBP was 60 ± 48 seconds. CONCLUSIONS Noninvasive beat-to-beat BP measurements are feasible during ECT and may be used to guide rapid therapeutic interventions during ECT-induced hemodynamic effects.

Abstract
OBJECTIVES Our primary objective was to conduct a systematic review to determine the differential effects of general anesthetic agents on electroconvulsive therapy (ECT) induced motor and electroencephalogram seizure duration. Our secondary objective was to determine the differential effects of induction agents on emergence time, recovery time, and the occurrence of adverse cardiac events and drug effects. MATERIALS AND METHODS We searched 4 electronic databases for randomized, crossover, and parallel trials. The weighted mean difference was calculated for continuous variables, whereas the risk difference was assessed for dichotomous variables. We combined crossover- and parallel-designed trials using the inverse variance method, and the random-effects model was used throughout. RESULTS Forty-one randomized trials involving 14 induction agents were included. The quality of trials was poor. Clinical and statistical heterogeneity were identified throughout. The most commonly studied comparison was methohexital versus propofol, where the mean motor seizure duration with methohexital was longer compared with that of propofol (weighted mean difference, 9.06 seconds; 95% confidence interval, 5.72-12.40). However, combining methohexital or propofol with a short-acting opioid prolonged seizure duration. Small but significant variations in emergence and recovery times were identified. Inadequate data were available to draw conclusions regarding adverse cardiac events and drug effects. No deaths were reported. CONCLUSIONS Whereas the relationship between ECT seizure length and efficacy remains unclear, all of the available induction agents in this review would be appropriate for ECT. When the clinician needs to prolong seizure length, methohexital or the addition of a short-acting opioid to methohexital or propofol should be considered. The small variations in emergence and recovery times should not govern the choice of an induction agent.

Abstract
The range of drugs available to provide anesthesia for patients undergoing electroconvulsive therapy (ECT) is ever increasing. Initially, anesthetic agents were selected on the basis of their capacity not to antagonize the induced seizure. This was not always a simple task because almost all general anesthetic agents have "in built" antiepileptic activity. Nonbarbiturate agents such as propofol have been successfully used as alternatives to thiopental and methohexitone, but this drug too has antiepileptic properties. Most recently, opioid-like drugs such as remifentanil have been used, and there has been renewed interest in ketamine, a phencyclidine derivative. Attention has also focused on whether the anesthetic agent selected may affect the cognitive impairment seen after ECT. Studies in this area are limited, but early results suggest that agents such as ketamine may have particular benefit. This article reviews the current literature dealing with anesthesia and postoperative cognitive impairment in general and with regard to ECT in particular.

Abstract
Electroconvulsive therapy (ECT) is a safe and effective treatment for severe and persistent depression, bipolar disorder and schizophrenia. Though ECT is now over 60 years old, it remains an underutilized treatment today. History, patient selection, safety, and characteristics of the treatment stimulus, technique, and medications used in ECT are reviewed. Dosing strategies, as pertaining to seizure threshold, will be considered. Mechanisms of action, especially with regard to serotonin, norepinephrine, and dopamine receptor expression will be discussed.

Abstract
Most electroconvulsive therapy (ECT) research indicates that seizure length does not correlate with clinical efficacy. However, it is common in practice for clinicians to undertake measures to prolong seizures if the duration seems to be too short, although there is no universally agreed upon minimum seizure duration for ECT. We felt it would be informative for the ECT field to report mean seizure durations over the course of treatments based on age and sex in a very large cohort to provide norms for reference. We studied 519 patients' courses of ECT and recorded treatment number, sex, and age along with motor and electroencephalogram seizure duration. We found that women have longer seizures, but only at the first treatment session. There is a strong inverse correlation between age and seizure length. The biggest drop in seizure duration along a course of treatments occurs between the first and second treatments; beyond that, seizure duration remains relatively constant.

Abstract
In general, seizure length does not correlate with clinical outcome with electroconvulsive therapy (ECT), but whether markedly short seizures are still therapeutic is unknown. Furthermore, seizure length effects on clinical outcome in ECT may be different among the various anesthetic agents available. Several studies have investigated the use of inhalational anesthesia in ECT with sevoflurane. In general, seizure length when reported has been in the range of typical values encountered in practice. We recently completed a randomized double blind trial with sevoflurane induction compared with thiopental. Seizure duration with sevoflurane anesthesia was 8 seconds shorter than with thiopental for electroencephalogram and 6.4 seconds shorter for motor, the latter just barely missing statistical significance. Absolute values for seizure duration with both sevoflurane and thiopental are well within typical ranges for those seen with the more commonly used methohexital as anesthetic.

Abstract
A recent lack of availability of the anesthetic agent methohexital in the United States allowed for a naturalistic study of the efficacy and the adverse effects of alternatives. Methohexital, propofol, and thiopental were compared as anesthetic agents for electroconvulsive therapy in 95 patients treated during a 23-month period in a general public hospital. Missed seizures and arrhythmias were infrequently observed (<4% for any agent). Methohexital was found significantly related to longer seizure durations in comparison with both other agents (P < 0.01). The use of propofol was associated with increased risk of missed seizure (8.9%) compared with methohexital (3.9%) and thiopental (3.2%). Propofol was also associated with higher doses of administered energy, with a statistically significant difference (P = 0.018) observed between propofol and thiopental. Although propofol required the greatest energy delivery, it was associated with the shortest seizure durations. Methohexital resulted in the longest seizure duration, and thiopental was associated with the least amount of energy delivery with an intermediate seizure length.

Abstract
Electroconvulsive therapy (ECT) is used in the treatment of severe psychiatric disorders. It involves the induction of a seizure for therapeutic purposes by the administration of a variable-frequency electrical stimulus via electrodes applied to the scalp. The original application of ECT in non-anaesthetised patients resulted in many traumatic effects and was replaced, in the early 1960s, with a modified ECT regimen that used anaesthesia with neuromuscular blockade. This remains the worldwide standard today. The development of modern ECT devices, with improved impulse modes, has also reduced the incidence of post-interventional cognitive adverse effects. The variety of centrally-acting co-medications administered and the cardiovascular effects occurring during the procedure make patients receiving ECT a challenge for the anaesthetist. The efficacy of ECT depends on the production of adequate seizures; however, the anaesthetic agents commonly used during ECT suppress the generation of convulsions. Therefore, the efficacy of ECT requires knowledge of anaesthetic precepts, understanding of the interaction between anaesthetic drugs and seizure activity, and awareness of the physiological effects of ECT as well as the treatment of those effects. Successful and safe ECT depends on the correct choice of anaesthetic drugs for the individual patient, which have to be chosen with respect to the individual concomitant medication and pre-existing diseases. This review provides information for the optimal selection, set-up and practice of anaesthetic drug treatment in ECT.

Abstract
A 53-year-old right-handed man was scheduled to receive 6 treatments of electroconvulsive therapy (ECT) for intractable depression. He was being treated for long-standing hypertension with nadolol and had no history of cardiopulmonary disease. Six months previously, he received 6 nondominant, unilateral ECT treatments. During each of these treatments, his blood pressure increased transiently to as high as 250/150, but he experienced no adverse consequence. He commenced the current course of ECT with well-controlled blood pressure (145/90). During his first bilateral treatment, his blood pressure rose to 280/160, and pulmonary edema ensued. Clinically evident pulmonary edema after ECT is an uncommon event that rarely has been described in the literature.

Abstract
We present a case of anesthesia for electroconvulsive (ECT) therapy that was complicated by emetic sensitivity to etomidate, fragile ictal threshold, and mild pseudocholinesterase deficiency. The anesthetic was designed in this patient taking all his issues in consideration. The mild pseudocholinesterase deficiency necessitated a (50-75%) reduction in succinylcholine dosage, careful monitoring of the train of four, and postictal amnestic coverage to prevent paralysis upon waking. The significant emetic response to etomidate prompted substitution to propofol and preemptive ondansetron. Propofol significantly raised the ictal threshold but significantly reduced the postprocedural emesis. Eventually, this clinical challenge was resolved with adjunctive use of low-dose etomidate and remifentanil. This combination preserved the ictal parameters, providing patient comfort, good clinical response, and therapeutic efficacy. Although seizure duration and quality often are restored with hyperventilation and caffeine, this case necessitated a return to etomidate for the restoration of satisfactory ictal parameters. Although this effect of remifentanil has been described with methohexital, and etomidate with alfentanil, to the best of our knowledge, this is the first reported case of adjunctive remifentanil with etomidate for preserving ictal threshold. The outpatient course of ECT was thus completed with all psychiatric and anesthetic goals satisfied: adequate seizure quality and duration, no paralysis upon waking, no post-ECT nausea and vomiting, and patient satisfaction. Anesthesiologists should be aware of factors influencing the seizure duration and, keeping in mind the coexisting medical conditions of the patient, adjustments should be made to get the best possible outcome.

Abstract
Seizure duration is an extensively studied and controversial indicator of treatment quality in electroconvulsive therapy. Previous research comparing the effect of the barbiturate anesthetics methohexital and thiopental on seizure duration has yielded conflicting results. A recent period of unavailability of methohexital in the United States allowed for retrospective comparison of seizure length as well as clinical improvement in treatment using each agent. Retrospective review was made of 837 treatments administered to 97 patients between January 2, 2002, and May 31, 2003, examining anesthetic, seizure duration, and Global Assessment of Functioning (GAF) scores of inpatients at hospital admission and discharge. Analysis of variance of treatments 2-5 showed no significant effect for anesthetic on seizure duration. Analysis on a treatment-by-treatment basis revealed a marginally significant trend toward shorter EEG seizures in the thiopental group at the second treatment (50.5 +/- 23.6 s vs. 61.1 +/- 27.9 s; P = 0.07) and fifth treatment (41.7 +/- 16.9 s vs. 51.8 +/- 24.0 s; P = 0.07). A difference approaching statistical significance revealed shorter convulsion length in the thiopental group at treatment 5 (29.0 +/- 12.3 s vs. 34.8 +/- 12.3 s; P = 0.07). Comparison of GAF score improvement at hospital discharge revealed no significant difference (GAF increase 26.4 +/- 9.4 for methohexital-treated patients vs. 24.8 +/- 12.0 for thiopental-treated patients; t = 1.00, df = 82, P > 0.1). Trends approaching significance in treatments 2 and 5 revealed shorter seizures in the thiopental group. However, data on clinical recovery reveals no greater improvement in the methohexital group. Thus, this study calls further into question the premise that choice of barbiturate anesthetic may affect clinical efficacy.

Abstract
The standard anesthetic agent for electroconvulsive therapy (ECT) has been methohexital. We compared sevoflurane, a short-acting halogenated anesthetic, to methohexital for induction in ECT. Twelve subjects received sevoflurane or methohexital on alternating treatment days. Seizure duration, time to administering ECT, emergence and recovery, as well as several hemodynamic measures were recorded. A total of 69 treatments were analyzed. When sevoflurane was used, seizure durations recorded by observation and by EEG, were shorter by 10 and 23 seconds, respectively. With sevoflurane, seizure duration remained, however, within a clinically acceptable range. Methohexital allowed faster administration of ECT and discharge from the recovery room (3.8 vs. 6.2 minutes and 40.8 vs. 47.0 minutes, respectively). No difference in the post-ECT hemodynamic changes was found between the two treatments. We conclude that, when indicated, sevoflurane could provide a suitable alternative treatment option to methohexital, but some limitations, including shortened seizure duration and potential side effects, should be kept in mind.

Abstract
Electroconvulsive therapy is an effective treatment for severe and medication-resistant depression. There have been no reports describing how a volatile anaesthetic affects haemodynamic responses, seizure duration, and recovery characteristics during electroconvulsive therapy. We carried out a repeated-measure crossover study to compare the effects on haemodynamic responses, seizure duration, and recovery characteristics of the following types of anaesthesia in electroconvulsive therapy: propofol alone, sevoflurane alone, and propofol combined with sevoflurane. We recruited 50 patients requiring electroconvulsive therapy for depression. For anaesthesia induction, 1.5 mg/kg propofol (condition P), 5% sevoflurane in oxygen following a vital capacity rapid inhalation induction (condition S), or 1.5 mg/kg propofol followed by 5% sevoflurane in oxygen (condition PS) was administered. Succinylcholine 1.5 mg/kg was then given. Electrical stimulation was administered after fasciculation. Measurements were obtained before anaesthesia induction (baseline), prior to succinylcholine administration, prior to electroconvulsive therapy, and at the peak after electroconvulsive therapy. After electroconvulsive therapy, peak heart rate and peak mean arterial pressure were highest in condition S. Whereas recovery time was longest in condition PS, motor seizure duration was significantly shorter than in either condition P or S. Electroencephalographic seizure duration was significantly shorter in condition PS than in condition P and significantly shorter in condition S than in condition P. Sevoflurane anaesthesia alone is most disadvantageous in terms of haemodynamics. Propofol-sevoflurane anaesthesia is advantageous in terms of haemodynamics, but disadvantageous in terms of seizure duration and recovery time. Propofol alone is most advantageous in terms of seizure duration.

Abstract
Serious adverse events associated with electroconvulsive therapy (ECT) are uncommon and consist mostly of cardiovascular complications, mainly arrhythmias. The risk of complications is increased in elderly and physically ill patients. In the current study, a 24-hour pre-ECT and 24-hour post-ECT Holter recording was performed on 26 elderly patients during their first ECT treatment. ECT caused a significant increase in bigeminy/trigeminy and supraventricular tachycardia, but did not increase other arrhythmias. Pre-ECT arrhythmias correlated with post-ECT arrhythmias. All patients in the current study completed the ECT course. Thus, the clinical significance of arrhythmias remains uncertain. The present findings support the usual practice of continuous electrocardiogram monitoring during ECT and recovery.

Abstract
UNLABELLED Methohexital is eliminated more rapidly than thiopental, and early recovery compares favorably with propofol. We designed this study to evaluate the recovery profile when methohexital was used as an alternative to propofol for the induction of anesthesia before either sevoflurane or desflurane in combination with nitrous oxide. One hundred twenty patients were assigned randomly to one of four anesthetic groups: (I) methohexital-desflurane, (II) methohexital-sevoflurane, (III) propofol-desflurane, or (IV) propofol-sevoflurane. Recovery times after the anesthetic drugs, as well as the perioperative side effect profiles, were similar in all four groups. A cost-minimization analysis revealed that methohexital was less costly for the induction of anesthesia. At the fresh gas flow rates used during this study, the costs of the volatile anesthetics for maintenance of anesthesia did not differ among the four groups. However, at low flow rates (< or = 1 L/min), the methohexital-desflurane group would have been the least expensive anesthetic technique. In conclusion, methohexital is a cost-effective alternative to propofol for the induction of anesthesia in the ambulatory setting. At low fresh gas flow rates, the methohexital-desflurane combination was the most cost-effective for the induction and maintenance of general anesthesia. IMPLICATIONS Using methohexital as an alternative to propofol for the induction of anesthesia for ambulatory surgery seems to reduce drug costs. When fresh gas flow rates < or = 1 L/min are used, the combination of methohexital for the induction and desflurane for maintenance may be the most cost-effective general anesthetic technique for ambulatory surgery.
