Abstract |
|
|
| The C-arm has become increasingly popular in the practice of orthopedics and fluoroscopic operations in a number of mane General Libyan Hospitals. Its wide use in the various orthopedic outpatient clinic has been noticed.. The purpose of this study is to evaluate the practice efficiency and radiation exposure to the main doctors and the specialists involved in each medical operation. At the same time to make comparison of the measured radiation exposure doses for the doctors and the specialists during the C-arm uses in the two main Libyan general hospitals namely Sbeha and Ghadra in Tripoli.
A number of doctors and specialists were chosen and agreed to receive OSL badges to be monitored, the radiation physicist used Optical Simulated Luminceinces Dosimeters (OSL) to measure the amount of radiation exposures namely the Deep, Shallow and Lens radiation doses in milli-Siveret (mSv). The average radiation doses were found to be 4-26,4-28, and 4-28mSv shallow, deep and Lens respectively for Sbeha hospital for a three months follow-up period. At the same time it was recorded 4-5,4-5and 4-5mSv for doctors operators at Ghadra hospital for a one month follow-up period. These values were higher than the annual permissible doses recommended by most International Radiation Protection Bodies. Other studies have reported radiation doses for the a single operation C-arm operation was 0.58mGy, compared with 0.2mGy for antero-posterior view and lateral view radiographs. This study reports two important findings. First, surprisingly, the C-arm used in both investigated hospitals have shown a higher radiation absorbed dose than standard imaging with plain radiographs. Second finding is the use of C-arm has facilitated and improved operation schedule time for patients.
