Introduction:
Image intensifier screening is commonly used in orthopaedic theatres. There has been concern regarding the cumulative radiation dose to surgeons and theatre personnel. The mini C-arm intensifier has been reported to scatter less radiation and have a reduced radiation dose to patients and theatre staff.
Materials And Methods:
A 2-month prospective survey of usage of radiographer-operated large intensifier and surgeon-operated mini C-arm image intensifier in a district general hospital orthopaedic theatre department.
Results:
A total of 153 cases required image intensifier screening - 63% used the large intensifier and 37% the mini C-arm intensifier. There were difficulties with equipment with the large intensifier in 16% of cases. There were delays in 11% of cases using the large intensifier. The total radiographer attendance time was 123 h. For the mini C-arm intensifier, there were no equipment difficulties or delays. The minimum radiographer time saved by using this machine was 21.9 hours.
Conclusions:
The mini C-arm intensifier has saved 15% of the radiographer workload with its current pattern of usage in our department. There have been no problems or delays as a result of its usage in theatre. Usage of the large image intensifier resulted in a 16% problem rate and 11% delay rate. Other departments are encouraged to consider acquisition of a mini C-arm intensifier to facilitate theatre throughput, reduce risk to the patient and theatre personnel, and reduce demands on the radiology department.
