Catheters, Tubes and Drains Functions • Placed within surgical wounds, tubular structures, and hollow organs • Assist with diagnosis • Restore functions • Promote healing • Prevent complications Characteristics • Hollow • Cylindrical shaped Not easily catagorized! “CHEST TUBE” Tubes can also serve as drains Catheters • • • • Remove fluids Remove objects -----Thrombi/stones Monitor body functions Insertion of fluids -----Contrast media, meds Characteristics of Catheters • Soft • Flexible • Polyvinyl chloride, Teflon, silicone, latex, polyethylene, and polyurethane etc… Common Catheters • Urinary Catheter—Typically drain urine NOTE: They may have other applications: example: Provide irrigation fluid within a duct. Classifications of Urinary Catheters • Urethral • Ureteral (Suprapubic) • Self-retaining • Non-retaining Urinary Catheter Sizing • French Scale for sizing • Size is determined by multiplying the diameter of the item in millimeters by three. • Available in a variety of sizes • May possess one or more openings “eyes” in the tip to allow for drainage Non-retaining Catheters • Temporarily inserted FOR: -Obtain urine specimen -Decompress bladder -Maneuver around obstruction Examples of Non-retaining Catheters • Robinson • Coude’ catheter Non-retaining catheters do not require the use of a drainage bag Self-retaining(indwelling) urethral catheters (Foley catheters) • Measure urinary output, over an extended period of time/bladder decompression (lengthy procedures) Characteristics of the FOLEY CATH • Balloon to retain the cath within the bladder continuous drainage, throughout procedure. • 5 or 30 cc capacity • Uses a syringe to inflate balloon with sterile water Two-way and Three-way Foley • Two-way balloon port and urine port • Three-way balloon port, urine port and irrigation/medication port • Some Foley catheters contain a thermometer at the tip Measure pt’s core temperature Self-retaining urinary catheters • Require drainage bag (urimeter) various types • Specialized 5 in 1 adapter to accommodate bag Suprapubic Catheter • Catheter placed through a surgical opening Examples: Foley, Pezzer (mushroom) and the Malecot (winged tip) These do not have a balloon for retention. Ureteral Catheters • • • • Placed in the ureters with cystoscope Decompress the kidneys Identify ureters Protect ureters Identification of ureteral caths • Identified by the tip (shape) • Typically contain radiopaque marker Examples: Whistle tip Olive tip Cone tip A drainage bag is needed if the catheter is going to be retained. Intravascular catheters • Infuse fluids • Obtain diagnosis • Monitor body functions • Remove thrombi Sized according to gauge, French method, may have a single or double lumen. May be inserted percutaneously or via a small incision….(cut-down) Intravascular Catheters • Venous access peripherally, upper extremity, or centrally Example: Subclavian or jugular vein. Angio-Cath =vascular cath Groshong = central vein cath Intavascular Catheters • Arterial Catheters • Inserted temporarily • Indwelling = provide info (arterial blood pressure) • Coronary artery angioplasty Intravascular Catheters • Fogarty = balloon tip catheter Passed beyond an obstruction, balloon is inflated, catheter is withdrawn, along with the obstruction. (thrombus, or stone) TUBES • • • • Remove air and fluids Decompression Maintain patency of lumen Administration of O2, anesthetic gases, meds and fluids (nutrition) Gastrointestinal Tubes • • • • Aspirate air and fluids from GI tract Passed through nose or mouth Passed through rectum May be inserted surgically GI Tubes • • • • Sump design Dual lumen Evacuation Air entry for equalization of pressure within structure • Reduce risk of damage to delicate tissues by preventing constant negative pressure. Airway Tubes Maintain patency of the upper respiratory tract • • • • ET tube Oral airway Nasal airway Tracheotomy tube Chest Tubes • • • • • Inserted percutaneously Treat pneumothorax Surgically inserted (separate stab wound) Evacuate air and fluid from pleural space Connected to a closed water drainage
