Radiation now becomes a dreadful effect as its outcomes are tremendous to be expected. As a
result, anesthetists become an inevitable target to the radiation exposure since they have
to monitor patients closely during the operation. Unfortunately, radiation may not have an
immediate sequelae, but an accumulation of adverse effects.
These sequelae happen by means of direct exposure and reflection. The reflected rays is
inversely proportional to the distance between the origin and the target. Practically, the
radiation source can be protected by individual cover and glass shield.
Siriraj hospital is a tertiary, general university hospital with 2,200 beds. Annually, an
Endoscopy centre has over 700 patients undergoing endoscopic retrograde cholangio
pancreaticography (ERCP). Normally, fluoroscopy for pancreatic and biliary ducts
visualisation is needed under anesthesia. Though the procedure is operated in a
well-equipped, radiating-protection room; many medical personnel including 1-2 endoscopists,
2 scrub nurses, 1-2 anesthetists and 1 x-ray man, still have a chance of irradiation.
During ERCP, all medical personnel particularly anesthetists are rinsed by radiation from
here and there. Though they always wear lead aprons and collar shields to protect themselves
from the rays, they are normally in the position - less than 1 meter - close to the
fluoroscopy.
Due to the advancement in technology, anesthetists can remotely monitor patients during the
surgical procedure. This might cause a lesser effect of ray upon them. As a result, whether
or not the positioning of anesthesia personnel relating to the distance of x-ray source
would help to alleviate the effect of radiation exposure.
