Aims and MethodBrief or missed seizures might indicate that electronvulsive therapy (ECT) is not being delivered effectively. This cycle of audit at an ECT clinic aimed to measure rates of brief or missed seizures in two study periods, before and after the acquisition of a more powerful ECT machine.ResultsThere was a significant reduction in the rate of brief or missed seizures in audit two. There was a significant increase in the restimulation rate in audit two, but without the desired effect of inducing adequate seizures.Clinical ImplicationsIneffective delivery of ECT might result in poor response to the treatment and should be minimised. Certain aspects of ECT delivery improved in the clinic studied but some patients received an ineffective second dose of electrical charge.

Subject Comparison

Aims and MethodTo compare methohexitone and propofol in electroconvulsive therapy (ECT). A retrospective within-subject comparison was made of the use of these drugs in separate courses of bilateral ECT in one clinic over 10 years. Patients taking mood stabilising or anti-epileptic drugs were excluded. The initial seizure threshold and seizure duration were of particular interest.ResultsThe median initial seizure thresholds were identical (75 mC). The median initial seizure duration with threshold stimulation was 25% shorter with propofol (21v.28 s). The median total numbers of treatments in the courses were identical (eight treatments).Clinical ImplicationsThe shorter seizure duration observed with propofol was not associated with a commensurate rise in the initial seizure threshold. The shorter seizure duration may therefore have no effect on the therapeutic efficacy of treatment.

Seizure Duration

Aims and MethodElectroconvulsive therapy should be effectively monitored and seizure duration accurately ascertained. We observed the seizure duration in both lower and upper limbs using the Hamilton ‘cuff’ method.ResultsThirty-nine seizures in 19 patients were observed. There were no statistically significant differences between cuffed and uncuffed limbs, nor between upper and lower limbs.Clinical ImplicationsAlternatives to the Hamilton cuff method to observe seizure duration need to be considered.

The Impact

Aims and Method We conducted a postal questionnaire survey of the practice of rapid tranquillisation among 215 consultant psychiatrists in the West of Scotland, before and after the withdrawal of droperidol by the manufacturer. Results One hundred and eighty questionnaires (84% of those sent) were returned. Droperidol had been used extensively, often combined with lorazepam, for rapid tranquillisation. The main replacement suggested for droperidol was haloperidol. About half of the respondents to our survey chose to comment on the withdrawal of droperidol. More than half of the comments were unfavourable, including lack of an adequate replacement and lack of consultation with the psychiatric profession. Clinical Implications The abrupt withdrawal of droperidol, partly for commercial reasons, was regrettable. There was no time for an adequate evaluation of possible replacement medications and a lack of consultation with the profession regarding the impact on clinical care.

Resistant Depression

Electroconvulsive therapy (ECT) remains the most effective therapy in treatment-resistant depression. However, the safety of ECT has been consistently questioned, particularly among elderly patients. We assessed the efficacy and safety of ECT in patients before and after 65 years old. The study was conducted between 2015 and 2018 and included 91 patients (61 under and 29 over 65 years old) with major depression undergoing ECT. The Hamilton Depression Rating Scale was used to evaluate efficacy. Cognitive functions were assessed using: MMSE, RAVLT, Trail Making Test, Stroop Test and Autobiographical Memory Interview-Short Form. ECT was more effective in older patients as compared to younger (p < 0.001). No serious adverse events were observed in either group. Increased blood pressure and arrhythmias were more common in the older compared to the younger group (p = 0.044 and p = 0.047, respectively), while disturbances of consciousness did not differ between groups (p = 0.820). Most of the cognitive functions remained unchanged compared to baseline, whereas the outcomes of MMSE, RAVLT and Stroop tests showed greater improvements in the older compared to the younger group (all p < 0.05). The decline in the retrieval consistency of autobiographical memory was more pronounced in the younger group (p = 0.024). ECT is a highly effective, safe and well-tolerated method of treating depression regardless of age.

Induction Agents

BackgroundThe induction agent propofol is known to reduce electroconvulsive therapy (ECT) seizure duration. It is assumed that outcome from depression is adversely affected by this agent. This study compares propofol and methohexitone as induction agents for ECT.MethodIn a prospective, randomised, double-blind study 20 subjects with major depressive disorder (DSM-III-R criteria) received propofol or methohexitone anaesthesia. The Hamilton Depression Rating Scale and Beck Depression Inventory were used to assess depression before therapy, at every third treatment, and at the end of therapy. Seizure duration was measured using the cuff technique.ResultsMean seizure durations (P < 0.01) and mean total seizure duration (P < 0.01) were shorter in the propofol group. There was no difference in outcome.ConclusionsUse of propofol may not adversely affect outcome from depression and it is not necessarily contraindicated as an induction agent for ECT. Our results should be interpreted cautiously, and larger studies are needed.

Objective: To evaluate the effects of low-dose fentanyl combined with a reduced dose of propofol on seizure duration and hemodynamic response during electroconvulsive therapy (ECT). Materials and Methods: Twenty-two patients with the American Society of Anesthesiologist Physical Status II to III undergoing ECT were enrolled in the present study. One hundred and five bilateral ECT sessions randomized to receive thiopental 2 mg/kg, propofol 1 mg/kg, and fentanyl 0.3 mcg/kg, followed by propofol 0.5 mg/kg. Succinylcholine 0.5 mg/kg was used for muscle paralysis. Seizure duration, awakening time and hemodynamic changes were compared between groups. Results: One hundred and five bilateral ECT treatments were randomized into thiopental group (n=35), propofol group (n=35), and fentanyl plus propofol group (n=35). The thiopental and fentanyl plus propofol groups had longer EEG and motor seizure durations than the propofol group, but the differences were not statistically significant. There was no difference in stimulus intensity across groups. However, fentanyl plus propofol group had statistically significant prolonged awakening time compare with thiopental group [mean difference 2.71, (95% CI 0.37 to 5.06, p=0.019)] and propofol group (mean difference 2.77, 95% CI 0.42 to 5.12, p=0.016). Only systolic blood pressure in propofol group was significantly lower than thiopental group [mean difference –10.4, (95% CI –19.4 to –1.38, p=0.018)]. There were no significant differences in diastolic blood pressure (df=2, F=2.546, p=0.083), heart rate (df=2, F=0.596, p=0.553), or oxygen saturation across group (df=2, F=2.914, p=0.059). Conclusion: Using a combination of low-dose fentanyl and low-dose propofol during ECT could be beneficial. Further investigation is needed to establish the optimal dose of propofol and fentanyl.
