EFFECT OF INTRODUCTION OF MINI C-ARM IMAGE INTENSIFIER IN THE ORTHOPAEDIC THEATRE

Abstract

Introduction: Image Intensifier screening is commonly utilised 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 patient and theatre staff.

Material and Methods: 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: 153 cases required image intensifier screening. 63% used the large intensifier and 37% the mini c-arm intensifier. The complication rate for the large intensifier was 16%. There were delays in 11% of cases using the large intensifier. The total radiographer attendance time was 123 hours. For the mini C-arm intensifier there were no complications or delays. The minimum radiographer time saved by using this machine was 21.9 hours.

Conclusion: 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 complications or delays as a result of its usage in theatres. Other departments are encouraged to consider acquisition of such a machine to facilitate theatre throughput and reduce demands on the radiology department.
