Image Frenchcatheter scale.gif thumb right 350px Sizing scale of the Frenchcatheter system The Frenchscale or French gauge system most correctly abbreviated as Fr, but also often abbreviated as FR or F is commonly used to measure the size diameter of a catheter . 1 Fr 0.33  mm, and therefore the diameter of the catheter in millimeters can be determined by dividing the French size by 3 D mm Fr 3 or Fr D mm 3 For example, if the French size is 9, the diameter is 3  mm. An increasing French size corresponds to a larger diameter catheter. This is contrary to Needle gauge comparison chart needle gauge size , where the diameter is 1 gauge, and where the larger the gauge the narrower the bore of the needle. The Stubs Iron Wire Gauge system is also commonly used in a medical setting, and is in fact more common for measuring needles, even though many find the Stubs system to be more confusing because the scale is non linear and inversely proportional. The French gauge was devised by Joseph Fr d ric Beno t Charri re, a 19th century Parisian maker of surgical instruments, who defined the diameter times 3 relationship. ref Iserson KV., J. F. B.

The dialysis catheter contains two lumen anatomy lumen s Venous Arterial This is a confusing terminology for layperson, because both lumens are in the vein. The arterial lumen typically red withdraws blood from the patient and carries it to dialysis machine, while the venous lumen typically blue returns blood to the patient from the dialysis machine . Flow rates of dialysis catheters range between 200 to 500 ml min. If a patient requires long term dialysis therapy, a chronic medicine chronic dialysis catheter will be inserted. Chronic catheters contain a dacron cuff that is tunneled beneath the skin approximately 3 8 cm. The tunnel is thought to add a barrier to infection. The most popular dialysis catheter sold on the market today is the split tip dialysis catheter. This catheter comprises two free floating tips. Catheter placement The catheter is placed in one of the large vein s. A common site is superior vena cava or SVC. An SVC catheter is placed by puncturing the internal jugular vein in the neck most often on the right side , and the catheter is then advanced downwards toward the chest. Alternatively an SVC catheter can be inserted via subclavian vein s right behind the clavicle the collar bone , often on the right. If the access of SVC is difficult, the femoral vein s can be used. This is an inferior option, however, because the groin site is more prone to infection and also because patient cannot sit upright. Complications Some common malfunctions of dialysis catheters include clotting, infection, and kinking. Fistulas versus catheters Cimino fistula Surgically created arteriovenous fistulas are preferred over catheters for patients with chronic renal failure, ref Huijbregts HJ, Blankestijn PJ.

Image Balloon catherter.png 200px right thumb Diagram of a balloon catheter. A balloon catheter is a type of soft catheter with an inflatable balloon at its tip which is used during a catheterization procedure to enlarge a narrow opening or passage within the body . The deflated balloon catheter is positioned, then inflated to perform the necessary procedure, and deflated again in order to be removed. Some common uses include angioplasty or balloon septostomy , via cardiac catheterization heart cath tuboplasty via uterus uterine catheterization Angioplasty balloon catheters Balloon catheters used in angioplasty are either of Over the Wire OTW or Rapid Exchange Rx design. When a balloon catheter is used to compress plaque within a clogged coronary artery it is referred to as a plain old balloon angioplasty or POBA. Balloon catheters are also utilized in the deployment of stents during angioplasty . Balloon catheters are supplied to the cath lab with a stent premounted on the balloon. When the cardiologist inflates the balloon it expands the stent. When the cardiologist subsequently deflates the balloon the stent stays behind in the artery and the balloon catheter can be removed. Stents that are used in conjunction with a balloon catheter are known as balloon expandable stents.

An arterial line , or art line , or a line , is a thin catheter inserted into an artery . It is most commonly used in intensive care medicine and anesthesia to monitor the blood pressure real time rather than by intermittent measurement , and to obtain samples for arterial blood gas measurements. It is not generally used to administer medication. Since many injectable drugs used in intensive care and anesthesia , such as sodium pentothal , may lead to serious tissue damage and even amputation if given in an artery the arterial line must be clearly marked to avoid accidental intraarterial injection of intravenous drugs. An arterial line is usually inserted in the wrist radial artery but can also be inserted into the elbow brachial artery , groin femoral artery , foot dorsalis pedis artery . Insertion is often painful however an anesthetic such as Lidocaine can be used to make the insertion more tolerable, but this can make insertion more difficult.
