Radiation Exposure Affecting Anaesthetic Personnel during Endoscopic Retrograde Cholangiopancreatography (ERCP)

Abstract.

Background 
During ERCP, anaesthetists are rinsed by radiation. The goal of study is to know the positioning of personnel relating to the distance of x-ray source.
Method
After IRB approval, the study was registered via ClinicalTrials.gov. NCT02985164 Inclusion criteria were the 222 patients who underwent ERCP procedure.
The PDSa1 and PDSa2 were placed on the outside and inside of a lead shirt respectively. The shirt-covered box was close to an anaesthetic machine (96.5 cm from the tube).
The PDSb1 and PDSb2 were placed on the outside and inside of the glass shield (204 cm from the tube) of control room.
Both position A and B were 160 cm. above the floor.
Data were expressed as mean and standard deviation. Categorical data were compared by using Chi-square test; while, the recorded data using dependent t-test. A p < 0.05 was considered statistically significant difference at 95% confidence interval.
Results
The amount of radiation recorded on the outside of the lead shirt-covered box and the glass shield was higher significantly than that of the inside. Though, the outer parts of these two locations exposed to the ray differently; it was not statistically significant.
Moreover, the shirt apron and the glass shield were effective to block the ray emission 96.22% and 95.46% respectively.
Conclusions
The amount of radiation affected anaesthesia personnel was approximately 5%. Distance appeared tobe the key factor for its hazard.
