In modern medical technology, balloon dilatation catheter has become an indispensable tool in interventional treatment. It is mainly used to dilate narrowed or occluded blood vessels and restore blood flow. Correct installation and use of balloon dilatation catheter is crucial to the success rate of the operation. The following are the installation steps and technical points of balloon dilatation catheter.
First, ensure the sterility of the surgical environment and prepare the necessary instruments and disinfection supplies. Operators need to wear sterile gloves and surgical gowns to minimize the risk of infection.
Next, check the integrity of the catheter. Carefully observe the surface of the catheter to ensure that there is no damage, wrinkles or cracks. At the same time, check the inner cavity and balloon part of the catheter to ensure that it is unobstructed.
When preparing the catheter, place the catheter in saline, gently rotate and advance it to remove the internal air. At the same time, check the inflation of the balloon to ensure that it can be inflated and deflated normally.
Then, start the catheter insertion operation. According to the patient's vascular condition, choose a suitable access route, such as the femoral artery or radial artery. Insert the catheter slowly and steadily until it reaches the predetermined position. During this process, closely monitor the patient's vital signs to ensure the safety of the operation.
After the catheter is in place, start balloon dilation. Inject an appropriate amount of contrast agent through the catheter and observe the expansion of the balloon. Adjust the dilation pressure and time to ensure that the blood vessels are fully dilated.
Finally, after confirming the treatment effect, slowly deflate and remove the catheter. Apply pressure to stop bleeding at the surgical site and closely observe the patient's condition.
Throughout the installation and use process, the operator needs to have rich experience and technical level. Correct installation and use can not only improve the success rate of the operation, but also reduce the occurrence of complications.
