A brief review of arterial catheterization techniques is included. The fixation techniques described in the literature and in commercial product information are essentially to tape or suture the arterial catheter flat against the skin. Often the wrist is immobilized in the dorsiflexed position to prevent kinking or dislodging of the catheter. We describe a simple device made from a gauze pad and tape to elevate and protect the arterial line while minimizing its kinking during wrist flexion.展开更多

DCA may influence the procedure of diagnosis and intervention of ischemic heart disease （IHD）. To cope with different subtypes of DCA, catheters like Amplatz, EBU, Leya, etc. were born at that moment, but these stan- dard catheters are used just in special cases and have so many sequences that a local hospital may not be able to keep all of them available routinely at any time. To overcome this problem, some centers perform angiography and intervention using modified catheters based on their own condition and have obtained some experiences. Catheter modification techniques used in these years are reviewed, and are stated respectively based on dealing with different subtypes of DCA to provide practical guidance for clinical diagnosis and intervention for IHD patients having DCA.展开更多
