Abstract

In the cath –lab, operator is mainly standing at right side of the patient. However, during pacemaker implantation（PMI）, operator is usually standing at left side of the patient. For that reason, all monitors are located at the right side of the patient during PMI which is opposite side in the other procedure. In this situation, a nurse has to move to outside of shielding plate to watch monitors during PMI, may result in more radiation exposure than that in usual procedure. The purpose of this study was to examine the appropriate standing position for the nurse to reduce radiation exposure during PMI. Radiation dose was measured by dosimeter at chest of nurse and outside of the shielding plate during PMI in 2 groups. In group A（n＝4）, nurse was positioned at right side of the patient’s head （Fig. 1）. In grope B（n＝3）, nurse was positioned at left side of the patient’s head （Fig. 2）. Radiation dose in grope B was significantly lower than that in grope A. However, care for patient during PMI in grope B was more difficult than that in grope A. More consideration is needed for reduction of radiation exposure for nurse during PMI. When the device is surgery to the left subclavian implantation, it was to the nurse chest. It was studied compared to the conventional right head side and the operator of the left head and the same side. The results indicated, the left head side radiation was lower. Left head side is a useful, because it is easy to observe and record. Therefore, the change of the standing position was useful for our hospital.
