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 151 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 16 was used to analyze all of the data. result: 1) venous obstruction and improper venous return had the highest recurrence rate of 89.4%, 2) removing the venous cannula and venting the venous path 86.8%, 3) 79.5% were unable to raise (act) more than 400. most significant injuries were caused by clots or thrombi during cpb (2.6%), 2) failure of the oxygenator (2.6%). most deaths were caused by an air embolism (5.29). conclusions: although the occurrence of human errors and mechanical disturbances cannot be predicted, they can be mitigated by the sharing of accidents and mistakes.
