indwelling catheters Flashcards
- healthcare devices inserted in a body cavity, vessel, or organ for a prolonged time to enable administration of medication, fluids, or to aid withdrawal of body fluids.
- are normally left in position for longer than a day and are of different designs and uses.
Indwelling catheters
TYPES OF INDWELLING CATHETERS
urinary catheters
central venous catheters (cvcs)
peripherally inserted central catheters (picc)
Inserted into the bladder to drain urine and often used in patients who are unable to urinate independently. Foley, Suprapubic
urinary catheter
Inserted into a central vein (like the jugular or subclavian) for medication and fluid administration, blood sampling, or hemodialysis.
central venous catheters (cvcs)
type of CVC inserted into a peripheral vein and advanced to the central veins for prolonged access.
peripherally inserted central catheters (picc)
leaking urine or being unable to control when u urinate
urinary incontinence
being unable to empty your bladder when u need to
urinary retention
catheters come in many sizes, mateials
latex
silicone
teflone
catheters types
straight
coude tip
common type of indwelling catheter. has a soft, plastic or rubber tube that is inserted into the bladder to drain the urine
foley catheter
3 main types of catheters
indwelling catheter
condom catheter
intermittent self-catheter
- immensely significant medical devices that can be applied in the management of numerous conditions, such as chronic and critical diseases
- Such catheters are inserted into large, significant veins in the body, ensuring constant vascular access, and can be employed for multiple reasons, such as giving medication or fluids, drawing blood samples, or checking blood pressure
central venous catheters
types of venous catheters
tunneled catheters
non-tunneled catheters
why small catheter
- minimizing trauma
- decreased risk of complications
- vein preservations and appropriate functionality
- ease of insertion and management
- central venous catheter that is inserted subcutaneously
- this type of catheter has an entry site and an exit site
- are a length of thin, long tubing.
- have a single lumen, or channel, through which fluids such as blood and drugs can pass, or multiple lumens.
- typically have a cuff, a small antimicrobial device located at the site of entry that is used to keep the catheter in place and prevent infection
- enable them to pass beneath the skin and into the venous system.
- usually intended for long-term use of at least a few weeks, up to several months or more, and can be used for a range of purposes, such as delivery of antibiotics or chemotherapy drugs.
TUNNELED CATHETER
- simply inserted into the vein, not going underneath the skin. These catheters do not have exit sites, only entry sites.
- narrow section of tubing that can accommodate the passage of drugs and fluids. They can have one or more lumens for the transfer of various fluids, and they can have some attachments at the tip, but are otherwise less complex in design compared to tunneled catheters.
- less difficult to insert overall and are intended for use over the short
term. - beneficial for giving a patient temporary access to specific fluids through routine IV therapy, or for conducting tests and examinations of the patient’s blood pressure and cardiovascular functions.
NON-TUNNELED CATHETER
have to be tunneled through a space under the skin and have both entry and exit sites
tunneled
pass straight into t he vein without any tunneling
non-tunneled
presence of a cuff, near the entry site
tunneled
usually be chosen for standard IV therapy and short-term procedures
non-tunneled
used for treating long-term illnesses
tunneled
aimed for short-term or temporary use
non-tunneled
designed t o be used for a minimum of two week s and may even be left in place for months at a time
tunneled
- devices used for long-term access to the venous system, particularly for patients who require frequent or continuous intravenous (IV) therapy
- designed to be accessed through the skin, allowing for medication administration, fluid therapy, or blood sampling without the need for repeated venipuncture.
