Cette étude visait à comparer la dose à la tête d’un cardiologue aux infirmières instrumentistes et infirmières en service externe lors d’une angiographie cardiaque. Un modèle quantitatif longitudinal corrélationnel a été utilisé pour examiner la relation entre la variable de la dose professionnelle reçue par l’opérateur médical par rapport à la dose reçue par l’instrumentiste et l’infirmière en service externe.
Aims This study aimed to compare the head dose of a cardiologist to scrub and scout nurses during cardiac angiography.
Design A correlational longitudinal quantitative design was used to examine the relationship between the variable of occupational dose to the medical operator when compared with the dose to the scrub and scout nurse.
Methods A quantitative analysis was performed on data collected during coronary angiograms (N=612) for one cardiologist and 22 nurses performing either the scrub or scout role between May 2015 – February 2017. Analysis was based on log-transformed dose levels and reported as geometric means and associated 95% confidence intervals.
Results It was found that scrub nurses received on average 41% more head dose than the cardiologist during diagnostic procedures and 52% higher doses during interventional cases.
Conclusion Nurses working in fluoroscopic cardiovascular procedures should be provided with appropriate training and protective equipment, notably lead skull caps, to minimize their occupational radiation exposure.
