Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Arm 1:before anesthesia induction 0.01mg/kg atropine intravenously will be given to patients at atropine group. once only before anesthesia induction.
Arm 2: before anesthesia induction 120 mg aminophylline intravenously will be given to patients at aminophylline group.once only before anesthesia induction.

All patients have more than 3 ECT sessions. Patients entered the study either non-premedicated as part of the control group, premedicated with atropine in the atropine group, or premedicated with aminophylline in the aminophylline group at the first three ECT sessions.Other ECT sessions (ECT sessions that after first three) were not included in the study. The group order for the patients’ ECT procedures had been determined randomly previously, using the closed envelope method. Thus, each patient was included in every group of first 3 ECT procedures in different orders randomly.

ECT sessions once every 2 or 3 days.Duration of each ECT sessions is 15-30 minutes.Duration of wash out period 2 days.

Patients were monitored for heart rate (HR) by three channel electrocardiography, noninvasive blood pressure, peripheral oxygen saturation (SpO2) and three channel electroencephalogram (EEG). Ten minutes before the anesthesia induction; 5 cc of isotonic saline, 0.01 mg/kg of atropine (5 cc), and aminophylline of 120 mg (5 cc) were infused intravenously to the control, atropine, and aminophylline groups, respectively. This was followed by anesthesia induction. During the anesthesia induction, propofol was administered in 30 seconds by titration (being no less than 1 mg/kg) until the eyelash reflex was lost. When patients became unconscious, the muscle relaxant, succinylcholine (0.5 mg/kg), was administered. Patients were ventilated with bag and mask supported with 100% oxygen during the procedure and was continued until complete awakening of the patients.
After adequate anesthesia and muscle relaxation, electroconvulsive therapy was performed using The Thymatron System IV device (Somatics, Inc, Lake Bluff, Ill) with bilateral fronto-temporal manner electrode placement. After Electroconvulsive therapy, we investigate the effects of atropine and aminophylline on respiratory problems incidance.

Outcomes
Primary outcome [1] 291590 0
Effects of atropine and aminophylline on respiratory problems that occur after electroconvulsive therapy.
The respiratory sounds were auscultated by the anesthesia physician before and after the procedure. Findings were recorded as normal respiratory sounds, fine crackles, coarse crackles or wheezing
Timepoint [1] 291590 0
immediately, 1minute and 2 minute after electroconvulsive therapy
Secondary outcome [1] 307132 0
post electroconvulsive therapy seizure's duration effect on respiratory problem incidence.
Seizure time was defined as the total time between the implementation of electricity until the last seizure seen at the end of the clonic phase (isolated forearm technique was used).
The respiratory sounds were auscultated by the anesthesia physician before and after the procedure. Findings were recorded as normal respiratory sounds, fine crackles, coarse crackles or wheezing.
Timepoint [1] 307132 0
immediately, 1minute and 2 minute after electroconvulsive therapy.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The present study is a randomized, double-blind, crossover trial. All patients had 5 ECT sessions. During the first three of which the patients entered the study either non-premedicated as part of the control group, premedicated with atropine in the atropine group, or premedicated with aminophylline in the aminophylline group. The group order for the patients’ ECT procedures had been determined randomly previously, using the closed envelope method. Thus, each patient was included in every group of first 3 ECT procedures in different orders randomly. Two different investigators completed the division of patients into groups, premedication administration, and data collection
