According to preoperative anesthesia consultations of the patients, 62.1% (n=36) were assessed to be in ASA 2 risk group and 34.5% (n=20) in ASA 3 risk group. Yaşlılık, elektrokonvülzif tedavi, güvenilirlik INTRODUCTION Electroconvulsive therapy is a somatic treatment method that is widely used throughout the world for various psychiatric disorders that are severe and resistant to treatment.1 Studies show that ECT is used in various populations and indications, and it is one of the most effective treatment methods that provide the fastest response in the treatment of depression, bipolar disorder and psychosis in geriatric patients. 2'3 ECT is a saving in some life-threatening conditions such as catatonia, neuroleptic malign syndrome, intense suicidal thoughts, refusal to eat and uncontrollable mania.4-6 It is observed that drug tolerance in the geriatric population is low due to age-related pharmacokinetic changes, and increased sensitivity to drug side effects such as anticholinergic effects and orthostatic hypotension. ...ECT is an advantageous treatment option in geriatric patients especially from the aspect of toxic presentations and drug interaction potential due to multiple drug use and comorbid diseases.7 In some studies conducted on patients with late onset geriatric depression and coexisting cerebral small vessel disease, it was shown that the efficacy of medical treatment was lower.8 It was demonstrated that response to ECT was better in geriatric patients who more frequently have neuropsychiatric comorbidities as compared to younger patients.9'10 Although it is very well known that ECT is an effective and reliable treatment option, it is a less preferred treatment option in geriatric patients in many places throughout the world. According to ASA risk classification, mortality rate in ASA 2 risk group and ASA 3 risk group patients is 0.27-0.4% and 1.8-4.3%, respectively.23'24 Our data show that complication rate was higher in ASA 3 patients than ASA 2 patients as expected (p=0.040).
