Characterizing cardiopulmonary arrest during interventional radiology procedures.

Area of Science:

• Interventional Radiology
• Cardiopulmonary Arrest
• Patient Safety

Background:

• Cardiopulmonary arrest (CPA) is a critical event that can occur in the interventional radiology (IR) suite.
• While many CPAs are preventable with careful case selection and preparation, understanding risk factors is crucial for improving patient outcomes.
• This study analyzes a series of CPAs in an IR setting to identify associated risk factors and procedural correlations.

Purpose of the Study:

• To analyze cardiopulmonary arrest (CPA) events in an interventional radiology (IR) department.
• To identify risk factors and patient comorbidities associated with CPA in the IR suite.
• To investigate the procedural context and outcomes of CPA events in IR.

Main Methods:

• A retrospective analysis of CPA events was conducted using a single-institution database of code team activations in the IR department from January 1, 2005, to May 30, 2011.
• Patient medical records were reviewed for medical history, American Society of Anesthesiologists (ASA) classification, sedation, and outcomes.
• Procedural data was obtained from the HI-IQ database.

Main Results:

• A total of 23 CPAs occurred during 36,489 procedures.
• The most common comorbidities were kidney disease (78%), diabetes mellitus (56%), and hypertension (48%).
• Patients undergoing dialysis shunt interventions had a significantly higher relative risk of CPA compared to arterial interventions (3.6; P = .045).

Conclusions:

• Kidney disease, particularly among dialysis-dependent patients, is a significant comorbidity associated with CPA in IR.
• Dialysis access-related procedures were frequently associated with CPA events.
• Improving case selection and preparation for patients with these risk factors may reduce CPA incidence in IR.
