What is the Purpose of Insertion of Central Venous Catheter
Central Venous Catheter is to obtain measurements of central venous pressure and administer drug preparations harmful to smaller lumen peripheral vein.
Definition-Insertion of Central Venous Catheter
Insertion of a Central Venous Catheter (IV Catheter designed for the purpose) into a large central vein with the catheter terminus usually near the right atrium.
The placement of a central venous line is an essential technique in the treatment of many hospitalized patients
- IV access (especially if difficult peripheral access)
- CVP monitoring
- ScvO2 monitoring/sampling
- Infusions of irritant substances (e.g. vasoactive agents, chemotherapy or TPN administration)
- Renal replacement therapy, olasmapheresis and apheresis
- Transvenous pacing
Large bore peripheral IV lines, RICC lines, Swan sheaths or IO access is preferred for rapid fluid fluid resusciation
- Respiratory failure
- Raised ICP (cannot tilt head down)
Can use femoral approach in all the situations above
- Obstructed vein (e.g. thrombus, or tumour)
- Overlying skin infection, burn or other disease process
- Hemorrhage from target vessel
- Uncooperative patient
- Course: from jugular foramen -> joins subclavian vein behind sternal extremity of clavicle
- Medial: internal and common carotid, 9th to 12th cranial nerves above common carotid + vagus
- Anterolateral: skin, superficial fascia, platysma, cervical fascia, sternomastoid, sternohyoid, omohyoid
- Posterior: transverse process of the cervical vertebrae, levator scapulae, scalenus medius and anterior, cervical plexus, phrenic nerve, thyrocervical trunk, vertebral vein, 1st part of subclavian artery
- Tributaries: inferior petrosal sinus, facial, pharyngeal, lingual, superior thyroid, middle thyroid, occipital veins
- Central approach: find 1cm above the apex of head of SCM and clavicle -> 60 degrees to skin aiming towards ipsilateral nipple (blood should be obtained within 3cm)
- Lateral/posterior approach: find 2-3 finger breaths above clavicle along posterior border of SCM, direct needle towards jugular notch (blood should be aspirated within 5cm)
- Anterior approach: identify the carotid and mid point of medial SCM border, aim toward ipsilateral nipple
- Superior: midpoint of clavicle
- Anterior: skin, external jugular vein, clavicle
- Medial: fascia, trachea
- Posterior: subclavian artery, first rib, scalenus anterior, phrenic nerve and fascia over pleura
- Approaches: supraclaviclar, infraclavicular and lateral
- NAVEL (nerve – artery – empty space – lymph node (lateral to medial)
- Boundaries of the femoral triangle are adductor longus and sartorius
- Approach: slight external rotation of hip, palpate pulse, medial to arterial pulsation
