2 Central Venous Line Placement
Goals Reduce anxiety about procedures Review basics Indications Complications Mechanics Improve familiarity with various catheter types Establish good habits and solid foundation Improve confidence and competency Ensure safe and sterile catheter placement

3 Central Venous Line Placement
Indications Hemodynamic monitoring CVP / Scv02 PA-Catheters (Swan-Ganz, RHC) Administration of hyperosmolar agents, vasopressors and other medications Temporary transvenous cardiac pacing Hemodialysis and plasmapheresis Lack of peripheral access

4 Central Venous Line Placement
Absolute contraindications None Relative contraindications Coagulopathy / thrombocytopenia Anatomic abnormalities Thrombus / stenosis Localized infection over insertion site Recent pacemaker insertion

5 Approach Advantages Disadvantages Internal Jugular Control of bleeding
PTX uncommon Lower infection rate (vs. femoral) PA-Cath (R) IJ Carotid artery injury Uncomfortable for Pt. Maintenance of dressings Tracheostomies IJ vein prone to collapse Subclavian More comfortable Clearer landmarks SC vein less collapsible Lowest infection rate PA-Cath (L) SC Risk of PTX SC artery difficult to compress (typically, SC vein is compressible) Should be avoided in CKD/ESRD Femoral No interference with CPR No risk of PTX Highest infection rate Difficulty for PA-Cath Femoral artery injury DVT NEJM 356;

6 Central Venous Line Placement
Complications-Distant Pneumo / Hemo thorax Air embolism Arrhythmia (catheter) Skin infection or bacteremia Stenosis or thrombosis of vessel Thoracic duct injury-chylothorax Nerve injury (brachial plexus, sympathetic chain, phrenic) Cardiac tamponade Complications-Immediate Failure to cannulate Pseudoaneurysm Catheter malposition Arteriovenous fistula Vessel laceration Hematoma Arrhythmia (wire or catheter) Air embolism Pneumo / Hemo thorax

7 Complication Rate / Site Comparison
IJ SC Fem Pneumothorax (%) < n/a Hemothorax (%) 0.4 – 0.6 Infection (rate per 1000 catheter days) 8.6 4 15.3 Thrombus (rate per 1000 catheter days) 1.2 – 3 0 – 13 8 – 34 Arterial Puncture (%) 3 0.5 6.25 Malposition low high NEJM 356;

8 Central Venous Line Placement
Preprocedure Prep Informed consent process – use procedure specific consents Review procedure, indications and alternatives Risks / Benefits Obtain written consent Coordinate procedure timing with bedside RN Enter Bedside Procedure Order in SCM Review equipment check list for needed supplies Review Preprocedure Checklist Procedure sign posted Procedure cart at bedside

9 Central Venous Line Placement
Preprocedure Prep Perform Time out at bedside with RN – document in SCM Sterile Technique Chlorhexidine 30 second friction scrub with 60 second dry time for dry site 30 second friction scrub with 2 minute “soak” time for moist site Maximum Barrier Precautions Sterile Gloves Long-sleeved gowns Full field drape Masks/Caps for all participants & observers Sterilize from chin to nipple to shoulder to ear (allows both IJ and SC to be accessed on the same side)

10 Central Venous Line Placement
PROCEDURE All IJ lines must be done with US guidance All lines must be transduced before dilation (verified by performing MD and RN) DOCUMENTATION Consent Bedside Procedure Order in (SCM) Time Out (SCM) US vessel evaluation note Procedure Note

14 Catheter type Description Advantages Disadvantages
Standard Triple Lumen (TLC) 7 Fr, 15 cm 18 gauge x 2 16 gauge Multiple access points Not optimal resuscitation line for hemorrhagic shock Multi-Access Catheter (MAC) 9 Fr, 11.5 cm Introducer (PA-Cath, TVP, “buddy catheter”) 12 gauge 9 Fr. 18 gauge x 2 (optional) Hemorrhagic Shock Resuscitation Line When used w/o “Buddy catheter” More difficult to insert Sharper tip on dilator increases risk of misplacement Shorter length with left sided placement Percutaneous Introducer Sheath (Cordis) Introducer (PA-Cath, TVP) Usually 8.5 FR Limited access points unless PA-Cath inserted Trauma Line Single lumen large bore central access Usually 8.5 FR, 8.89cm Hemorrhagic Shock Resuscitation line Limited access points No introducer sheath Hemodialysis Dual Lumen Catheter Usually 13.5 FR Used for HD and plasmapheresis Not to be used except in extreme emergency for general IV access

15 Infusion Rate Comparison
MAC Distal (9fr) 33,000 cc/hr Proximal (12g) 13,000 cc/hr Distal w/ 8fr catheter 10,500 cc/hr TLC Distal (16g) 3,400 cc/hr Medial (18g) 1,800 cc/hr Proximal (18g) 1,900 cc/hr MAC: pt with GIB, pt who needs a TIPS, or banding, RP bleed. Always have a 2nd sterile assistant when doing a MAC line. There is an abrupt transition point where dilator ends and catheter begins, you often need a second set of hands to retract neck tissue. Attach blue cap immediately, once pierced by dilator it could entrain air. Don’t forget the 2 port adapter cuts flow rate from 30L to 10L/hr.

16 Choosing the Catheter Size
Pt. Height RIGHT Subclavian LEFT Subclavian RIGHT Internal Jugular LEFT Internal Jugular 4'6" - 4'9" inches 12 16 13 17 4'10"- 5'1" inches 14 18 5'2" - 5'4" inches 15 19 5'5" - 5'8" inches 20 5'9" - 6'0" inches 21 6'1" - 6'4" inches 22 These charts can be found on the CVC/HDC equipment checklist and on display in the conference room. When deciding which site to use, please consider if the patient is a potential dialysis candidate. Left sided hemodialysis catheters have a greater chance of being malpositioned. Always use the longest catheter available for groin lines: 25” Cook CVC and 24” Niagra HDC. HD Catheters: 15 cm Right IJ, 20 cm Left IJ, 24 cm Femoral Can adjust for particularly small or large patients

17 Choosing the Catheter Size
When deciding which site to use, consider if the patient is a potential dialysis candidate. Avoid SC catheter placement Left sided hemodialysis catheters have a greater chance of being malpositioned. For HD catheters risk of atrial perforation Always use the longest catheter available for groin lines: 25” Cook CVC and 24” dual lumen HDC.

18 Proper Use of Adjustable Suture Wing
Used to secure catheter when not inserted to manifold (“hub” aka - full catheter length) Must apply both white rubber clamp and red rigid fastener to avoid catheter migration secure with 4 sutures: adjustable suture wing and catheter manifold (hub) Do not bend catheter in excess in order to suture at catheter hub, keep straight as possible Dressing placed over adjustable suture wing only, manifold sutures open to air Provider procedure note documentation and daily RN documentations MUST include catheter depth catheter depth or securement concerns

19 Documenting Catheter Depth
Centimeter markings on catheter are used to determine catheter depth Catheter length is printed on manifold (hub) Double hash mark equals full catheter length as indicated on manifold Single hash marks indicate one centimeter increment Document catheter depth where catheter exits the skin in daily access assessment Double hash mark = full catheter length Single hash mark = one centimeter increments measure catheter depth at skin exit 5 cm increment numerical marking Catheter length printed on manifold

20 Post-Line Insertion Chest X-ray
Delayed PTX is not unusal – have low threshold to obtain repeat CXR if clinical s/s PTX Single plane view of ICU CXR is suboptimal to evaluate catheter malposition Transduce waveform via monitor --(can be done without CXR, will demonstrate intravascular placement and arterial vs venous vessel or extravascular placement) Blood gas if intravascular may be useful but clinical conditions can confound interpretation If extravascular catheter is suspected t/c Chest CT w/ contrast

21 Coagulopathic Patients
Caution with INR > 2.5, PT or PTT > 2x normal, Plt < 50k, or untreated uremia (not on HD). The more parameters fulfilled, increases the cumulative effect on hemostasis. Consider correction (FFP, platelets, ddavp, HD) Consider IJ placement under US over SC Coagulopathic state and /or thrombocytopenia are RELATIVE CONTRAINDICATIONS and warrant a risk/benefit discussion with attending

22 Helpful Reminders Recommend restraining all patients during central line placement. (even awake or intact) Keep everything within reach (needles, wire, catheter, flush) Always place patient in trendelenberg (>15 degrees) For SC catheters, placing a rolled towel/sheet in between the scapulae can help “open” the clavicular angle & allow easier passage of the needle underneath the clavicle If wire does not pass: Re-attach syringe and aspirate (see if still in vessel) Lower angle of needle (and aspirate) If wire “clears” the tip of the needle, then consider structural reason (thrombus, anatomic abnormality, ect.) If the wire does not come out easily, give GENTLE traction and try rotating the wire. DO NOT pull firmly on the wire! Remove catheter and wire together if able If unable to remove wire call vascular

23 Ultrasound Guided Vascular Access

24 Transducer Transmits and receives the ultrasound beam
Contacts the patient’s skin Takes thin slices of object being imaged Rotated or angled to change views Beam Profile Width of the beam (1mm) Length of beam 38mm 38mm 1 mm

25 Ultrasound Basics Fluid (i.e. blood) is black b/c near complete transmission of U/S waves occurs Bone and air cause marked reflection and appear white (in B – mode) Strong reflection creates an acoustic shadow obscuring distal imaging (bone shadow)

26 Ultrasound Basics Most large vessels are easily visualized with U/S probes Arteries are pulsatile, difficult to compress and thick walled Veins are non-pulsatile, easily compressible, engorge w/ Trendelenburg or Valsalva and thin walled

27 Transverse Orientation – IJ

28 Longitudinal Orientation – IJ

29 Transverse Orientation – Subclavian

30 Longitudinal Orientation: Subclavian

31 Guide wire in Longitudinal View

32 Jugular Vein Thrombosis

33 Jugular Vein Thrombosis
Acute thrombus can appear “black” or “cloudy” on US exam Always evaluate the whole neck ensuring IJ is fully compressible along the entire length Presence of small caliber anomalous vessels can be indicative of past or present clot or stenosis There is no real definition of “acute” (thrombus) in hours, days, etc. This is why we need to ensure the compressibility.
