Performance of a radiation protection cabin during implantation of pacemakers or cardioverter defibrillators.
BACKGROUND
Pacemaker implants are associated with a high cumulative exposure of the operators to radiation. Standard radiation protection with lead aprons is incomplete and the cause of spine disorders. A radiation protection cabin offers complete protection by surrounding the operator, without requiring a lead apron.


METHODS
We randomly and evenly assigned 60 patients undergoing implantations of permanent pacemakers or cardioverter defibrillators (ICD) with (a) a radiation protection cabin (cabin group, n = 30) versus (b) standard protection with a 0.5 mm lead-equivalent apron (control group, n = 30). Radiation exposure was measured using personal electronic dosimeters placed on the thorax, back, and head of the operator.


RESULTS
The patient, procedural, and device characteristics of the 2 study groups were similar. All procedures in the cabin group were performed as planned without increase in duration or complication rate compared with the control group. The mean radiation dose to the head, normalized for fluoroscopy duration, was significantly lower in the cabin (0.040 +/- 0.032 microSv/min) than in the control (1.138 +/- 0.560 microSv/min) group (p < 0.0001). The radiation doses to the thorax (0.043 +/- 0.027 vs 0.041 +/- 0.040 microSv/min) and back (0.038 +/- 0.029 vs 0.033 +/- 0.018 microSv/min) in the cabin versus control group (under the apron) were similar.


CONCLUSIONS
The use of a radiation protection cabin markedly decreased the exposure of the operator to radiation, and eliminated the need to wear a lead apron, without increasing the procedural time or complication rate during implantation of pacemaker and ICD.
