Effects of Ciprofol Anesthesia on Learning and Memory Function and Antidepressant Effects of ECT in Depressive Patients

Study Overview
=================
Brief Summary
-----------------
In this clinical study, propofol was used as the positive control, and a randomized controlled trial design was used to observe the effects of ciprofol anesthesia on learning and memory function and antidepressant efficacy in patients with ECT. A total of 390 depressed patients who were to undergo electroconvulsive therapy were selected and randomly divided into two groups, namely the propofol group (n=195 cases) and the ciprofol group (n=195 cases). The patients in the propofol group were given propofol 1.5mg/kg + succinylcholine 1mg/kg, and the patients in the ciprofol group were given ciprofol 0.4mg/kg and succinylcholine 1mg/kg, and the patients were given electroshock after anesthesia treat.

Detailed Description
-----------------
Ciprofol injection, whose active component (HSK3486) is propofol analogue, is a novel treatment for anesthesia induction and maintenance. It has been authorized for commercialization in China on December 14, 2020. The purpose of this experiment is to know the effect of ciprofol on the antidepressant effect and cognitive function of depressive patients after electroconvulsive therapy. Ciprofol is very similar in structure to propofol, so propofol was used as the control group in this experiment.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Active Comparator: Propofol injection group (1.5mg/kg)<br>The patients in the propofol group were given intravenous injection of propofol 1.5 mg/kg and succinylcholine 1 mg/kg in turn, and the interval between each drug administration was 1 minute, and electroconvulsive therapy was performed after the patients were anesthetized. | Drug: Propofol<br>* Propofol is a commonly used anesthetic in clinical practice and is often used before ECT.<br>* Other names: 2,6-Diisopropylphenol;|
| Experimental: Ciprofol injection group(0.4mg/kg)<br>The patients in the ciprofol group were given intravenous injection of ciprofol 0.4 mg/kg and succinylcholine 1 mg/kg in turn. The interval between each drug administration was 1 minute, and the patients received electroconvulsive therapy after anesthesia. | Drug: ciprofol<br>* A new type of anesthetic drug, Ciprofol, which is newly listed and has national independent intellectual property rights, is an analogue of propofol. Its chemical name is 2-[(1R)-1-cyclopropylethyl]-6-isopropyl-phenol, and it acts on GABAA receptors like propofol. Compared with propofol, ciprofol is 4-5 times more potent, which can significantly reduce the amount of anesthetics.<br>* Other names: 2-[(1R)-1-cyclopropylethyl]-6-isopropyl-phenol;|
