The subclavian approach to the placement of a central line is preferred because femoral placements may be complicated by deep venous thrombosis or infection, and internal jugular sites carry an increased risk of infection. Sterile technique is a requirement during insertion. The skin should be prepared with chlorhexidine-gluconate (2%) or povidone-iodine. Ultrasound guidance improves the likelihood of entering the desired vein without injury to neighboring structures. With or without radiological guidance, the best results are obtained by practitioners who perform the procedure frequently. After the catheter is inserted, it should be firmly sewn to the skin to keep it from migrating in and out of the insertion site. An antibiotic-impregnated patch covered by a sterile dressing should be placed at the insertion site. The catheter should be manipulated as infrequently as possible during its use. Dressing changes are carried out using sterile technique. IV tubing and solutions and injection caps also should be changed as required by the agency’s protocol. Health care professionals are responsible for preventing, assessing for, and managing central venous therapy complications (e.g., air embolism; cardiac tamponade; chylothorax, hemothorax, hydrothorax, or pneumothorax; local and systemic infections; and thrombosis). Documentation should include preprocedure and postprocedure physical assessment of the patient, catheter type and size, insertion site location, x-ray confirmation of the placement, catheter insertion distance (in centimeters), and the patient’s tolerance of the procedure. Maintenance care procedures also should be fully documented. The site should be carefully inspected for inflammation, and any drainage should be cultured. When catheter-related infections are suspected, the catheter tip provides valuable information about infection sources in cases of sepsis. The tip should be cut off with sterile scissors and dropped directly into a sterile specimen container.</span></div> <div class="separator" style="clear: both; text-align: center;"> <a href="http://www.tabers.com/tabersonline/repview?type=539-30&name=c240p0" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="320" src="http://www.tabers.com/tabersonline/repview?type=539-30&name=c240p0" width="200" /></a></div> <div class="separator" style="clear: both; text-align: center;"> <br /></div> <div style="text-align: justify;"> <br /></div> <div style="text-align: justify;"> <span style="color: #b45f06; font-size: large;"><b>CENTRAL VENOUS CATHETER (SUBCLAVIAN:</b></span></div> <div style="text-align: justify;"> <span style="color: purple; font-size: large;">Condom catheter:</span></div> <div style="text-align: justify;"> <span style="color: purple; font-size: large;">A specially designed condom that includes a collection tube attached to the distal end.

Catheters are medical devices that can be inserted in the body to treat diseases or perform a surgical procedure. By modifying the material or adjusting the way catheters are manufactured, it is possible to tailor catheters for cardiovascular, urological, gastrointestinal, neurovascular, and ophthalmic applications.</span></div> <div style="text-align: justify;"> <span style="color: #274e13;"><span style="font-size: large;"><br /></span> </span></div> <div class="separator" style="clear: both; text-align: justify;"> <a href="https://upload.wikimedia.org/wikipedia/commons/thumb/f/f5/Urinary_catheter.JPG/1024px-Urinary_catheter.JPG" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><span style="color: #274e13;"><img border="0" height="211" src="https://upload.wikimedia.org/wikipedia/commons/thumb/f/f5/Urinary_catheter.JPG/1024px-Urinary_catheter.JPG" width="320" /></span></a></div> <br /> <div style="text-align: justify;"> <span style="font-size: large;"><span style="color: #274e13;"><br /></span></span></div> <div style="text-align: justify;"> <span style="font-size: large;"><span style="color: #274e13;"><br /></span></span></div> <div style="text-align: justify;"> <span style="font-size: large;"><span style="color: #274e13;">Catheters can be inserted into a body cavity, duct, or vessel. Functionally, they allow drainage, administration of fluids or gases, access by surgical instruments, and also perform a wide variety of other tasks depending on the type of catheter.[1] The process of inserting a catheter is catheterization. In most uses, catheter is a thin, flexible tube ("soft" catheter) though catheters are available in varying levels of stiffness depending on the application. A catheter left inside the body, either temporarily or permanently, may be referred to as an indwelling catheter (for example, a peripherally inserted central catheter). A permanently inserted catheter may be referred to as a permcath (originally a trademark).</span></span></div> <br /> <br /> <div style="text-align: justify;"> <span style="font-size: large;"><span style="color: #274e13;"><br /></span></span></div> <div style="text-align: justify;"> <span style="font-size: large;"><span style="color: #274e13;">The ancient Syrians created catheters from reeds. "Katheter — καθετήρ" originally referred to any instrument that was inserted, such as a plug. It comes from the Greek verb "kathiemai — καθίεμαι" meaning "let down", because the catheter was 'let down' into the body.</span></span></div> </div>
