Detaillierte Beschreibung
Various pharmacological agents have been investigated in the Electroconvulsive therapy (ECT) procedures. Dexmedetomidine, widely used for sedation, attenuates stress-induced sympathoadrenal responses, reduces postoperative agitation, improves intraoperative hemodynamic stability, and decreases anesthetic requirements during a variety of surgical procedures. As an α2-adrenergic receptor agonist, dexmedetomidine has been shown to attenuate the hyperdynamic response associated with ECT. Remifentanil is a potent μ-opioid receptor agonist characterized by its rapid onset and ultra-short duration of action due to rapid metabolism and elimination. An additional advantage of opioid agonists is their ability to suppress sympathetic responses without increasing the seizure threshold. Consequently, short-acting opioid analgesics such as remifentanil have been recommended as adjuncts during ECT because they improve hemodynamic stability, facilitate rapid recovery, and may prolong seizure duration.
Both dexmedetomidine and remifentanil have been widely used for sedation in anesthesia practice for many years, and several studies have evaluated their use during ECT . Furthermore, the prescribing information for both agents indicates that they are approved for sedation in operating rooms and intensive care units.
The primary objective of this study is to compare the effects of dexmedetomidine and remifentanil on the hemodynamic response in patients undergoing ECT. The secondary objectives are to evaluate seizure duration and recovery characteristics. We anticipate that the findings of this study will contribute to the identification of a safer and more effective anesthetic approach for patients undergoing ECT.

Placebo-Komparator: Control group (Group C)
Whereas patients in the control group (Group C) will receive normal saline infused over 10 minutes (total volume: 30 mL).
Immediately after completion of saline infusion, anesthesia will be induced with propofol at a dose of 1 mg/kg in Group C. If an adequate depth of anesthesia is not achieved, as determined by failure to respond to verbal commands and loss of the eyelash reflex, supplemental propofol will be administered in 10 mg increments at 10-second intervals until adequate anesthesia is achieved.
The total propofol dose administered will be recorded.
Following loss of consciousness, rocuronium 0.3 mg/kg will be administered intravenously to all patients to achieve muscle relaxation, after which patients will be ventilated with 100% oxygen for 90 seconds.
A suprathreshold electrical stimulus will then be delivered using the ECT device

Aktiver Komparator: Dexmedetomidine group (Group D)
Patients in the dexmedetomidine group (Group D) will receive intravenous dexmedetomidine at a dose of 0.5 μg/kg infused over 10 minutes (total volume: 30 mL).
Immediately after completion of the study drug infusion, anesthesia will be induced with propofol at a dose of 1 mg/kg.
If an adequate depth of anesthesia is not achieved, as determined by failure to respond to verbal commands and loss of the eyelash reflex, supplemental propofol will be administered in 10 mg increments at 10-second intervals until adequate anesthesia is achieved.
