Retrospective Analysis of Bypass-Related Complications at Iran's Cardiovascular Surgical Centers

Introduction: In addition to the well-known benefits of cardiopulmonary bypass (CPB), there are also certain possible risks, some of which are avoidable and some of which are accidental. In addition to CPB, potentially life-threatening consequences include human error and mechanical disruptions. The purpose of this study is to conduct a retrospective analysis of CPB accidents in Iranian cardiovascular surgery departments.Methods: This study included ۱۵۱ Iranian perfusionists who were evaluated using a questionnaire created by the researchers. The questionnaire recorded all participants' demographic information as well as their experiences with human errors (e.g., perfusionist fatigue and drowsiness; errors in CPB circuit arrangement; and so on) and mechanical disturbances (cooling-warming circuit, oxygenator failure, electrical disruption, and so on). SPSS Version ۱۶ was used to analyze all of the data.Result: ۱) venous obstruction and improper venous return had the highest recurrence rate of ۸۹.۴%, ۲) Removing the venous cannula and venting the venous path ۸۶.۸%, ۳) ۷۹.۵% were unable to raise (ACT) more than ۴۰۰. Most significant injuries were caused by clots or thrombi during CPB (۲.۶%), ۲) failure of the oxygenator (۲.۶%). Most deaths were caused by an air embolism (۵.۲۹).Conclusions: Although the occurrence of human errors and mechanical disturbances cannot be predicted, they can be mitigated by the sharing of accidents and mistakes.
