Placing Peripheral IVs, Central Venous Catheters, and Intraosseous Lines AFAMS Resident Orientation April 8, 2012 Outline • Basic principles of IV infusions • Indications, contraindications, acceptable locations, and complications of placing – Peripheral IVs – Central Lines – Intraosseous Access • Brief descriptions of technique for each vascular access procedure Basics of Intravenous Infusion • IV Flow rate is proportional to catheter radius4 • IV Flow rate is inversely proportional to catheter length • Therefore, fluid flows faster in a wide short catheter than in a narrow long catheter • The smaller the catheter Gauge, the wider the catheter radius – 14 G is wider than 20 G Peripheral IV Indications • Sample Blood • Infuse fluids • Infuse blood products • Infuse IV medications Peripheral IV Contraindications • Extremities with – Massive edema – Burns or injuries – Cellulitis • Mastectomy – Concern for adequate vascular flow • Indwelling fistula – Avoiding possible vascular damage near a fistula Complications • Insertion site infection • Superficial Thrombophlebitis • Interstitial Leakage Placement a Peripheral IV • Practice Universal Precautions – Always wear gloves – Consider face and eye protection • Avoid needle sticks – Do not recap needles – Do not put needles back in the sheath – Dispose in proper sharps container • Always start peripheral and move proximal if initially unsuccessful Placement a Peripheral IV: Equipment • Gloves and protective equipment • Appropriate size IV catheter (14G – 25 G) • Tourniquet • Gauze • Transparent Dressing (Tegaderm) • IV bag with tubing Placement a Peripheral IV • Wear gloves • Apply tourniquet proximal to insertion site • Palpate vein • Clean skin with alcohol prep • Remove protective cover of catheter • With left hand stabilize the vein while you insert catheter, bevel up, with your right hand • Angle of insertion should be approximately 35 degrees Placement a Peripheral IV • As catheter is advanced, watch for blood “flash” • Once “flash” is seen, slowly advance needle 1 cm, then stabilize needle and advance catheter into vein • Remove tourniquet • Attach catheter to saline lock • Dispose of needle in sharps container Indications for Central Line Placement • Infusion of sclerosing or hyperosmolar medications – Pressors, chemotherapy, TPN, etc. • Access for hemodynamic monitoring – Swan-Ganz Catheter • Lack of peripheral access • Transvenous pacing • Aspiration of venous air (Intra-operative issue only) Central Venous Access Locations • Internal Jugular Vein • Femoral Vein • Subclavian Vein • Uncommon – Arm (brachiocephalic vein) – External Jugular Vein • Usually cannulate dwith a peripheral IV General Concepts to Central Venous Catheter Placement • Obtain informed consent • Set up your equipment • Position the patient • Practice Universal precautions – Gown – Gloves – Eye protection General Concepts to Central Venous Catheter Placement • Clean the area with chlorhexidine or betadine • Drape the area to reduce infection risk • Use plenty of lidocaine superficially and deeper in the soft tissue External Jugular Vein Advantages • Easy to learn to perform • Essentially peripheral venipuncture • Pneumothorax is uncommon • Arterial puncture is uncommon Disadvantages • Inability to cannulate vein common (≈ 20 %) • Practice required to use guide wire • Wire or catheter may perforate veins • May interrupt CPR during code External Jugular Anatomy Femoral Vein Advantages • Does not interrupt CPR during a code Disadvantages • If pulse is absent, vein may be hard to locate • Vein does not collapse • Longer delivery time of drug to heart • Easy access to central circulation • Risk of thrombosis (0.5 %), infection (1 to 2 %), colonization (25 to 30 %) and inadvertent puncture of the femoral artery (5 to 8 %) with vascular injury • Useful for hypovolemic shock Femoral Vein Anatomy Femoral Vein Technique • Position patient supine • Measure halfway between Anterior Superior Iliac Spine and Pubs Symphysis along the inguinal ligament – Femoral Artery site • Palpate Femoral Artery • Target venopuncture 2 cm inferior to inguinal ligament and 2 cm medial to femoral artery • Advance needle at 20-30 degrees while aspirating until venous flash is seen Femoral Vein Technique • After venous flash remove syringe • Advance wire through needle • Remove Needle holding pressure over puncture site – NEVER LET GO OF THE WIRE! • Advance catheter over wire • Remove wire Femoral Vein Access Complications • Infection • Thrombophlebitis • Retroperitoneal hemorrhage • Inadvertent puncture of bladder • Vasovagal reaction • A-V fistula • Hematoma • Femoral artery thrombosis or embolism Internal Jugular Advantages • More sterile than femoral vein • Can do hemodynamic monitoring with IJ – Swan-Ganz catheter • Can do with ultrasound assistance • Quick delivery of drug to the heart Disadvantages • Risk of pneumothorax • Risk of carotid artery puncture • Cannot be done while CPR is being done Internal Jugular Vein Superficial Anatomy Internal Jugular Vein Venous Anatomy Internal Jugular Vein • Patient supine, 15-degree angle in Trendelenberg, head down • 3 Different approaches – Central – Anterior – Posterior • Right side IJ is preferred – Dome of pleura is lower – Straight line to right atrium – Thoracic duct not in the way Internal Jugular Vein Technique • Standing at head of patient • Visualize triangle formed by heads of sternocleidomsatoid 5 cm superior to clavicle • Palpate carotid pulse with left hand • Use finder needle, insert at 30-45 degree angle aiming toward ipsilateral nipple • If blood is not aspirated within 2.5 cm slowly withdrawal needle and reposition Internal Jugular Vein Technique • After venous flash remove syringe • Advance wire through needle • Remove Needle holding pressure over puncture site – NEVER LET GO OF THE WIRE! • Advance catheter over wire • Remove wire Subclavian Vein Insertion Advantages • Superficial vein • Can remain in place for long time • Can do central hemodynamic monitoring (IJ is preferred) Disadvantages • Difficult to compress in bleeding situation • High rate of pneumothorax • Risk of subclavian artery injury Subclavian Venous Access Subclavian Venous Access • Position patient in 15 degrees of Trendelenberg • Abduct patient’s arm • Insert Needle 2-3 cm inferior to the midpoint of clavicle • Keep needle parallel to floor • Advance needle under clavicle and towards sternal notch Subclavian Vein Technique • After venous flash remove syringe • Advance wire through needle • Remove Needle holding pressure over puncture site – NEVER LET GO OF THE WIRE! • Advance catheter over wire • Remove wire Comparison of Central Access Sites Arm External Internal Jugular Jugular Subclavian Femoral Ease/Safety 1 2 4 5 3 Long term use 4 3 2 1 5 Success 5 4 1 3 2 Complications 1 2 3 4 3 Swan-Ganz Use 5 2 1-right 4-right 3-left 3-left 3 note: 1 = best, 5 = worst.
