ARTERIAL CANNULATION FOR INVASIVE BLOOD PRESSURE MONITORING

Indications:

Induced hypotension

Anticipation of wide blood pressure swings

End organ disease necessitating precise beat-to-beat blood pressure regulation

Multiple arterial blood gas samples (or other samples)

ARTERIAL CANNULATION FOR INVASIVE BLOOD PRESSURE MONITORING

Contraindications:

Avoid in arteries without documented collateral blood flow

Vascular insufficiency (Raynauds phenomenon)

5

ARTERIAL CANNULATION FOR INVASIVE BLOOD PRESSURE MONITORING

Procedure:

Position

Palpation

Local if awake

20-22 ga catheter over needle at 45 degree angle

Flashback

Lower to 30 degrees

Catheter advanced into artery like an IV

Proximal pressure, connect transducer

 

6

CENTRAL VENOUS CATHETERIZATION

Indications:

Monitor CVP

Rapid administration of fluid for hypovolemia and shock

Infusion of caustic drugs

TPN

Aspiration of air emboli (cranial surgery)

Venous access for lack of peripheral access

7

CENTRAL VENOUS CATHETERIZATION

Contraindications:

Renal cell tumor extension into the right atrium

Fungating tricuspid valve vegetations

Ipsilateral carotid endarterectomy

8

CENTRAL VENOUS CATHETERIZATION

Complications:

Infection

Air or thrombus emboli

Arrhythmias

Hematoma

Pneumothorax

Hemothorax

Cardiac perforation

Trauma to nearby nerves

Carotid artery puncture

9

CENTRAL VENOUS CATHETERIZATION

Procedure:

Choice of cannulation site: internal jugular(IJV) vs. subclavian vein (SCV)

Trendelenberg position

Full aseptic technique

Bactericidal skin preparation

Sterile drapes

Locate the triangle formed by the two heads of the sternocleidomastoid (STM) muscle and the clavicle

Local if awake

25 ga finder needle for the IJV, along the medial border of the lateral head of the STM, toward ipsilateral breast nipple at an angle of 30 degrees to the skin

Verify as venous blood

18 ga needle in same path as finder, J-wire introduced

Silastic catheter advanced over wire

Guidewire removed

Place thumb over the catheter hub

Connect tubing

Suture

Sterile dressing

Confirmation via CXR
