9 points of attention for radiation protection of C-arm machine in operating room

Working in the operating room will inevitably be exposed to radiation from the C-arm machine. Studies have proved that in the case of improper protective measures, the amount of radiation received by doctors in the operating room may exceed the limit and affect the body. Even a small dose of radiation damage, under long-term radiation exposure, will gradually accumulate and produce pathological damage cumulative effects, such as deformities. In order to better protect ourselves and ourselves, the editor of the EEG machine has compiled 9 points of attention on the radiation protection of the C-arm machine in the operating room.

C arm machine

In accordance with the radiation protection principles of C-arm radiation practice, dose limitation and potential exposure risk limitation, protection and safety are extremely optimized, the radiation protection of C-arm machine must first do the following:

1. Strengthen the training of C-arm machine protection technology for medical staff.

2. Adopt comprehensive protection measures such as shielding protection, time protection and distance protection. Use additional devices such as bedside protective screens, lead curtains, and lead protective covers for X-ray tubes to minimize the impact of ionizing radiation on the health of medical staff; EEG machine

3. Strengthen the X-ray protection awareness of clinical medical staff. Surgical personnel at the bedside must wear personal protective equipment: lead clothing, lead caps, lead collars and lead glasses, etc. The lead equivalent is not less than 0.25mm to avoid direct exposure to X-rays on sensitive parts of the body.

4. Non-irradiated parts of the patient. Use lead curtains, lead bedspreads and other lead rubbers for shielding, especially pay attention to the protection of radiation-sensitive organs and tissues, such as eyes, thyroid, thymus, gonads, etc., so as to minimize the radiation damage of the C-arm machine. degree;

5. Shorten the irradiation time. The exposure dose of medical staff and patients is positively related to the exposure time. The longer the exposure time, the more times the exposure dose of the EEG machine medical staff and the subject will be. The more harmful the ionizing radiation will cause to the body;

6. Familiar with the performance of C-arm machine. Use the C-arm machine to adjust the function of digital image storage and reproduction, and adopt the intermittent perspective method to control the entire exposure time, and avoid lingering exposure;

7. Archive through the method of direct retention of film. Can achieve time-saving, non-repetitive completion of the guidance effect and diagnosis;

8. Make distance protection. When the C-arm machine is exposed, minimize the number of surgical personnel at the bedside, and unrelated personnel should stay away from the C-arm machine irradiation field.

9. In order to achieve the warning effect of ionizing radiation during irradiation of C-arm machine, a working indicator light linked to the exposure of C-arm machine can be set. The working indicator light flashes during each exposure to avoid unnecessary radiation by medical staff at the bedside .
