The issue of cancellation and its adverse consequences has been the focus of many clinical studies, especially in surgical wards. Canceling the planned procedure on an intended day negatively impacts the hospital’s finances and the patient’s health (
1,
2). However, no previous study has assessed the pattern and reasons for cancelation in ECT patients, and the literature is limited to a few case reports (
3). Clearly, providing strategies to prevent ECT cancelations is as important as surgical cases. Indeed, ECT is the last life-saving option in resistance cases and those at risk of suicide (
4-
6). Therefore, regular and uninterrupted treatment sessions are crucial for these cases. Medical team, the scheduled patients to receive ECT are sometimes canceled on the appointed day, which causes anxiety among relatives and disrupts the patient’s healing process. Inappropriate dental conditions, inadequate consultations, abnormal laboratory tests, and paraclinical results, which need further evaluation, are among the reasons for cancellation. It should be considered that, in some situations, the procedure under general anesthesia can be fatal for the patient, and there is no other choice but to cancel it. During the ECT process, significant hemodynamic fluctuations occur due to stimuli of the sympathetic and parasympathetic nervous systems (

8). Therefore, it is important to find a practical solution so that the treatment session is not canceled while the patient is managed safely. The successful management of ECT patients results from teamwork and proper communication between anesthesiologists and psychiatrists (
9). It has been well documented that this procedure was considered inhumane before anesthesia was used in the ECT process (
10). In this regard, the hospital’s anesthesia team designed a checklist for the optimal preparation of patients who were candidates for ECT treatment. This checklist was designed according to the valid related references pointing to the high-risk situations and taking into account the common causes of cancelations in our department (
11,
12). Based on this checklist, the necessary consultations and paraclinical evaluations were performed. To the best of our knowledge, it was the first study that discussed the issue of cancelation among ECT patients and tried to provide practical preventive strategies, a topic that seems to have not been sufficiently focused on.
