Radiation hazard to operating room personnel during operative cholangiography
Abstract:
During operative cholangiography, the surgeon and other operating room personnel are exposed to scattered radiation and its potential hazards. It was determined that a surgeon standing at the side of the patient during cholangiographic filming would receive 3.2 mR per film. Exposure would be only 0.5 mR per film if the surgeon stepped back 75 cm (2.5 ft) from the patient. This simple measure would reduce the monthly exposure of a surgeon who performs four cholangiograms per week from approximately 205 to 32 mR. The use of the new electronic video-disc recording systems and lead aprons can substantially reduce the amount of radiation exposure related to fluoroscopy. The prudent surgeon, recalling that no level of radiation may be totally safe, should use techniques that provide maximal protection for himself and all operating room personnel during performance of operative cholangiography.
Insights
Surgeons can minimize radiation exposure during operative cholangiography by stepping back 75 cm. This simple change significantly reduces radiation dose for operating room personnel, enhancing safety.
Area of Science:
- Radiology
- Surgical Safety
Background:
- Operative cholangiography poses radiation risks to surgical teams.
- Scattered radiation during the procedure is a significant concern.
Purpose of the Study:
- To quantify radiation exposure during operative cholangiography.
- To evaluate protective measures for surgical personnel.
Main Methods:
- Measuring radiation dose at different distances from the patient.
- Assessing the impact of lead aprons and electronic recording systems.
Main Results:
- Standing 75 cm from the patient reduces radiation exposure from 3.2 mR to 0.5 mR per film.
- This distance adjustment can lower monthly exposure from 205 mR to 32 mR for surgeons performing four procedures weekly.
- Electronic recording and lead aprons further decrease fluoroscopy-related radiation.
Conclusions:
- Simple adjustments in surgical positioning can drastically reduce radiation exposure.
- Implementing protective measures is crucial for the safety of all operating room personnel.
- Minimizing radiation exposure during operative cholangiography is essential, as no radiation level is considered completely safe.
