An Investigation of the Knowledge of General Surgeons in Fars Province in Terms of the Complications of Central Venous Stenosis and Thrombosis Following Insertion of a Double-Lumen Subclavian Catheter

Central venous stenosis and thrombosis are much more likely to occur following the insertion of a double-lumen catheter in the subclavian vein rather than the internal jugular vein. This study aimed to evaluate the knowledge and awareness of general surgeons in Fars province regarding the complications of central venous stenosis and thrombosis following the insertion of a double-lumen subclavian catheter. This descriptive cross-sectional study was conducted among general surgeons in Fars province through a researcher-made questionnaire designed and used to assess their knowledge regarding the complications of stenosis and thrombosis following central catheter insertion in the subclavian vein. Among the participants, 63% of them used the internal jugular vein as the preferred method of inserting a double-lumen catheter, while 36% of them preferred the subclavian method. Also, 46% of the participants were sufficiently aware of the possibility of stenosis and thrombosis following insertion of a double-lumen subclavian catheter, and 47.4% assumed that the probability of thrombosis was less than 30%. The results of this study indicate that a significant percentage of general surgeons in Fars province are not aware of the high risk of stenosis and thrombosis in the subclavian vein following the insertion of a double lumen catheter. Therefore, it is recommended that constant and up-to-date training sessions be held for general surgeons in selecting the appropriate vein and using ultrasound in the insertion of a double-lumen catheter.
