If you put a drape on top of a patient, you're doing absolutely nothing to protect them from radiation because it's coming from below the table.

Update Course Rewind: Intraoperative Radiation Safety 2022

guideline Best practice fluoroscopy includes positioning the patient as close as possible to the image intensifier or flat plate detector. ↗
▶ Ep 3 · 0:27
clinical Pulse mode is a feasible option in most pediatric surgery fluoroscopy applications. ↗
▶ Ep 3 · 0:27
clinical Every time the magnification setting is used on the fluoroscopy machine, it significantly increases the radiation dose to both the patient and the room. ↗
▶ Ep 3 · 0:27
clinical Collimation focuses the x-ray beam to a specific area, which increases image detail and clarity. ↗
▶ Ep 3 · 0:27
clinical Collimation decreases the total radiation dose to the patient because the surface area getting irradiated is smaller. ↗
▶ Ep 3 · 0:27
clinical Collimation decreases radiation dose to the room. ↗
▶ Ep 3 · 0:27
opinion Best practice guidelines for fluoroscopy are not routinely taught to surgeons in the United States. ↗
▶ Ep 3 · 0:27
clinical In standard C-arm configuration, raising the bed as far as possible brings the patient close to the image intensifier. ↗
▶ Ep 3 · 0:27
clinical In small patients, overexposure can occur if collimation is not used appropriately. ↗
▶ Ep 3 · 2:55
quote I just tell the tech, collimate down on the mediastinum. ↗
▶ Ep 3 · 3:19
quote The texts know this, but the texts don't come in the room until all the drapes are on and they don't know where the shields are. So it is a commonly made mistake and it's a bad mistake. ↗
▶ Ep 3 · 3:19
clinical By convention, the x-ray source in the C-arm is placed below the table. ↗
▶ Ep 3 · 3:19
clinical The patient and table protect personnel in the room from radiation when the x-ray source is below the table. ↗
▶ Ep 3 · 3:19
clinical Placing a radiation shield drape on top of a patient does nothing to protect them from radiation because the x-ray source is below the table. ↗
▶ Ep 3 · 3:19
clinical Fluoroscopy machines utilize automatic brightness control, which increases x-ray energy when something blocks the beam from reaching the image intensifier. ↗
▶ Ep 3 · 3:19
clinical If a radiation shield is in the fluoroscopy field, automatic brightness control increases radiation exposure to the patient. ↗
▶ Ep 3 · 3:19
guideline If shielding is used, it must be placed below the patient to be effective. ↗
▶ Ep 3 · 3:19
clinical Fluoroscopy technicians know that shields should be placed below the patient, but they enter the room after drapes are placed and don't know where shields are located. ↗
▶ Ep 3 · 3:19
quote If you put a drape on top of a patient, you're doing absolutely nothing to protect them from radiation because it's coming from below the table. ↗
▶ Ep 3 · 3:19
quote So if that shield is in the field, you're actually increasing exposure to the patient. ↗
▶ Ep 3 · 5:21
clinical Shielding can be placed underneath the gel pad or similar patient positioning device. ↗
