بررسی عوامل موثر در بروز تشنج محیطی در بیماران تحت درمان با الکتروشوک درمانی از دیدگاه بیهوشی

Aim and Background: Electroconvulsive therapy(ECT) is one of the most effective and prompt therapies forsevere psychotic issues. This study aims to distinguish the impact of age, disease and medications on the seizurecaused by ECT.Methods and Materials: 123 patients were studied and categorized according to their age, psychotic disorderand medications (anti-psychotics, anti-depressive or both of them). The correlation of these variants with seizureduration were discussed in every session of ECT.The seizure duration was recorded based on clinical convulsionand EEG parameters. The failure or success of ECT was evaluated by seizure time measurement to be less orgreater than 20 sec, respectively.Findings: There was no significant difference observed between men and women in regards to the averageseizure duration in different sessions (6 sessions) (P=0.25).There was either no significant difference observedin seizure duration in various sessions between patients under and above 40 years of age(P=0.45). Againno significant difference was seen in seizure duration among patients with psychotic and mood disorders orbetween patients using anti-psychotic or anti- psychotic and anti- depressant drugs for therapy, respectively(P=0.38 and P=0.14).Conclusions: Accurate knowledge about patients who are candidate to receive Electroconvulsive Therapy isvery important. Type of psychologic disorder, type of drug protocol and the number of sessions of ECT, all arethe factors which should be considered in every ECT procedure.Keywords: Electroconvulsive therapy, seizure duration, success rate
