  • UNC preferred site – in the hospital manual
  • Seldinger originally described this technique in 1953 for percutaneous arteriography.
  • Transcript

    • 1. LITTLE MORE ABOUT CATHETERS…………All our Cliny catheters are made from medicalgrade silicone which is well known for itsbiocompatible properties. Silicone is "gentle on the body" and less likelyto cause irritation,OTHER MATERIALS ARE ALSO USED:LATEXPOLYMERSMETALS(early catheters)
    • 2. WHY CATHETER ARE REQUIRED? ?
    • 3. For a patient who is suffering from a disease of the kidneyor bladderFor a patient who is suffering from a neurological disorderFor diagnosis where high precision level is desiredIn surgical process in order to decrease the level ofinvasiveness degreeAnesthetic control and infusionIV lineCatheters are widely used in fields ofcardiology,urology,nephrology ,ENT
    • 4. indwelling catheter: Anindwelling, or Foley catheter isa thin, flexible drainage tubethat drains body fluid or urine
    • 5. Permcath: A Permcath is a flexibleplastic tube that can be put into a veinor in required body part for a longtime period.
    • 6. Location Advantage DisadvantageInternal Jugular • Bleeding can be recognized • Risk of carotid artery puncture and controlled • PTX possible • Malposition is rare • Less risk of pneumothorax • Easy to find vein • Highest risk of infectionFemoral • No risk of pneumothorax • Risk of DVT • Preferred site for • Not good for ambulatory emergencies and CPR patients • Fewer bad complications • Most comfortable for • Highest risk of PTX, should notSubclavian do on intubated pts conscious patients • Should not be done if < 2 years • Vein is non-compressible
    • 7. NOW CATHETERIZATIONTECHNIQUES…….
    • 8. TYPE OF CATHETERIZATION:CARDIAC CATHETERIZATIONCentral Venous CatheterizationPulmonary ArteryCatheterizationUrinary catheterizationCoronary catheterizationHemodailysis catheterization
    • 9. Pulmonary Artery Catheterization
    • 10. Also known as a “Right Heart Catheter”. The positionfrom distal end to proximal end is: Pulmonary Artery,Right ventricle, right atrium, vena cava, subclavian vein. Subclavian Tip in Pulmonar yArtery
    • 11. Parts:1. Balloon2. Openings: a. Distal (tip) b. Proximal c. Injectate3. Thermister probe4. Ports a. Balloon b. Distal Port c. Proximal port d. Injectate5. Electronics connection6. Oximeter
    • 12. Measurements recorded in “mmHg”These values are a measurement of the fluidpressure in the Pulmonary Artery, and Vena Cavarespectively. These values are useful inquantifying and diagnosing cardiopulmonarydisease.
    • 13. SvO2Saturation of Venous OxygenMeasured in the Pulmonary ArteryThis reading is the Only TRUE mixedvenous.
    • 14. Careful! These calculationsare subject to error!
    • 15. ~5 mmHg
    • 16. ~8 mmHg ~6 l/min
    • 17. Question ?
