Abstract
Despite efforts for patient stabilization before radiologic procedures, cardiopulmonary arrests still occur. The purpose of our study was to define the incidence, patient characteristics, and outcomes of patients having cardiopulmonary arrest in a radiology department. We retrospectively reviewed patients sustaining cardiopulmonary arrest in the radiology department from 2002 to 2007. Patient characteristics and outcomes were documented. Descriptive statistics were calculated. Over the 6 years of the study, 1,480,578 radiographic procedures were performed, and 27 patients sustained a cardiopulmonary arrest in the radiology department for an incidence rate of 0.002 per cent. The average patient age was 66 years (range, 35 to 88 years); 12 were male (44%). Radiological procedures were diagnostic in 15 cases and therapeutic in 12 cases. The most common locations for arrest were in the CT area (9 patients) and the vascular procedures area (8 patients). The most common preprocedural patient locations were the hospital wards (11 patients [41%]), the emergency department/trauma bay (5 patients [19%]), the intensive care unit (4 patients [15%]), and an outpatient setting (four patients [15%]). Nineteen patients (70%) survived the initial code, 14 patients (52%) survived 24 hours, and 9 patients (33%) survived until discharge. Survival to discharge was significantly impacted by body mass index (P = 0.005) and type of radiologic procedure (P = 0.04) but not by the preprocedure patient location. Cardiopulmonary arrest occurring in the radiology department is a rare but potentially lethal occurrence. Patients undergoing vascular access procedures may be an at-risk group. Further study is needed to evaluate potential risk factors for cardiopulmonary arrest occurring in the radiology department.
