ABSTRACT
Objective To normalize the individual dose monitoring for nationwide radiological workers and to improve individual dose monitoring ability of radiological health monitoring service institutions. Methods The 2017 annual intercomparison was carried out of nationwide external radiation individual dose monitoring result, with summary and analysis completed. Results A total of 283 monitoring service institutions were involved in the 2017 annual intercomparison. Of them, 249 were qualified, 45 excellent and 34 unqualified. The excellent rate was 15.9％ and the pass rate 88.0％. Conclusions Most of individual dose institutions could meet better the requirements by the intercomparison, but some deviated from the references to some degree. It is necessary to strengthen the laboratory operation and standardize data processing and to improve the accuracy end precision of measurement result .
ABSTRACT
Objective To explore the effects of warm water insufflation applied in difficult colonoscopy on its success rate, insertion time, operation difficulty level and tolerance of patients. Method 200 cases of the difficult defecation of non-narcotic colonoscopy, IBS and always has a history of pelvic/abdominal surgery patients, were randomly divided into warm water infusion group (experimental group) and traditional method of air insufflation group (control group), then compare the differences of the success rate of the two groups of patients, the insertion time and degree of tolerance in patients. Results All the patients completed the investigation in this study, neither bowel perforation nor other complications occurred. Experimental group success rate of the whole colon examination, the insertion time, the operator satisfaction and check again wishes were significantly higher than that of control group (P 0.05) in Polyp detection rate. Conclusion Warm water insufflation colonoscopy can effectively improve the tolerance and accelerating the colonoscopy in patients with difficult insertion process, improve work efficiency, and is an ideal method, which is worth of promoting.
