In this study we aim to investigate the relationship between our anesthesia practice and post procedure complications after MRI scanning with sedation. This is a retrospective, single center observational study. All patients undergoing MRI scan during the study period will be included.

In this study we aim to investigate the influence of patient characteristics and anesthesia choice on possible complications in patients undergoing MRI under sedation retrospectively.

After one of the routine sedation protocol used in our department was chosen and applied according to the physical status of the patient and the physicians decision, the datas of the patients will be recruited to the study from the medical records . Patient characteristics (age, gender, weight, height), ASA (American Society of Anethesiology) classification, associated diseases will be recorded . After the procedure was completed all the complications during the 2 hours waiting period in the recovery room will be recorded from the medical records. All the complşcation and recovery times will be recorded from the medical records. Whether the patient received radiocontrast material or not will also be recorded.
