Introduction

Understanding the anatomic relationships of the large veins used for placement of central catheters is key to successful cannulation and avoidance of complications.

Common Details for Venous Catheterization

When internal jugular or subclavian vein catheterization is selected, the patient is placed in the Trendelenburg position with a roll put lengthwise between the shoulders. This position helps distend the veins, improve the line of access, and reduce the incidence of air embolism. The head is rotated slightly away from the proposed insertion site.

Internal Jugular Vein Catheterization

The internal jugular vein is located in the triangle formed by the two heads of the sternocleidomastoid muscle and clavicle in the anterior neck (Fig. 40-1).

Which functional line runs from one shoulder across the back to the opposite leg?

Back Functional Line Runs from one shoulder across the back to the opposite leg.

What is the function of arm lines?

The Arm Lines connect seamlessly into the all the other “main” lines. Their functionality could be summarized as bringing things towards us, pushing things away.

What is the purpose of the spiral line?

The main function of the Spiral Line is to cross all planes of movement. It connects the knee to the hip joint and determines the efficiency of knee-tracking. The spiral line begins at the mastoid process, runs down the splenius capitis, into C-7.

What is the organ of structure?

Where is the second front line?

The second Superficial Front line begins at the anterior inferior iliac spine (AIIS), stretches down the rectus femoris, into the tibial tuberosity, following the tibialis anterior, and spreading down the dorsal portion of the foot.

What is the deep front line?

Deep Front Line. A core line that begins deep on the sole of the foot and runs up the inside of the leg to the front of the hip joint and across the pelvis to the front of the spine and on up through the thoracic cavity to the jaw and the bottom of the skull. The Deep Front Line comprises the body’s myofascial core.

What are the most important facts to know about the arcuate line?

However, when present, the arcuate line is of great clinical significance, especially for surgeons, as Spigelian hernias usually present close to the arcuate line. Additionally, the arcuate line indicates where the inferior epigastric vessels perforate the rectus sheath .

Why is the brachial approach to catheter placement problematic?

The brachial approach of placing arterial catheters is traditionally considered problematic and prone to complication because of the paucity of arterial collateral circulation. It should not be accessed for cannulation to avoid the risk of ischemic injury to distal part of the extremity.

Which artery is bordered by the Achilles tendon?

The posterior tibial artery is the second major arterial supply to the food running posterior to the medial malleolus in a groove that is bordered by the Achilles tendon posteriorly. There is a higher potential for occlusion of this artery because of its smaller caliber as compared to the dorsalis pedis artery.

How long does it take for a radial arterial catheter to be occluded?

Both radial and ulnar pulses are occluded forcefully by manual palpation for 10 to 15 seconds or until blanching of the palm are noted. The ulnar arterial occlusion is released. If the blanching resolves quickly, the patency of the ulnar artery is enough to perfuse the hand in spite of a complete or partial occlusion of the radial artery.

What is needed to insertion of an arterial catheter?

Additionally, these kits help with adherence to evidence-based essential steps to minimize the risk of catheter-related infection during the insertion. At a minimum, these include the appropriate-sized arterial catheter and the corresponding search needle that usually is available in an arterial catheter package that includes lidocaine, gauze tissue, sterile gloves, mask and gowns, and chlorhexidine solution for aseptic cleansing. The transducer, connecting tubing and monitor cable system must be available before the insertion of the catheter. The waveform obtained after connecting the arterial catheter ensures the successful placement in the lumen of the artery.

Which artery is the largest arterial supply of the lower extremity?

The femoral arter y gives the largest arterial supply of the lower extremity. The pulsation of this major vessel is a well-known landmark in juxtaposition to the femoral vein. The location of this pulse divides the inner third of the inguinal ligament to the outer two-thirds. The femoral artery is the single trunk that perfuses the lower extremity as it divides into 4 major branches as it wraps around the structures of the thigh. There are no other major collateral vessels for the arterial supply of the lower extremity. Therefore, complete obstruction of the femoral artery leading to ischemia may have devastating consequences.

Is the ulnar artery the same as the radial artery?

The ulnar artery is smaller and not as readily palpable as the radial artery. It is used less commonly but may be accessed situations where other options have been exhausted.

Why do you brush up on arterial line placement?

Arterial puncture and cannulation, also known as arterial line placement or “a-line,” is commonly performed in the ED to allow for continuous blood pressure measurement and frequent arterial blood gas sampling.

What is the Allen test?

Clinical pearl: Allen’s test is used to determine whether sufficient collateral circulation to the hand is present. Before attempting line placement, apply firm pressure to both radial and ulnar arteries until the patient’s hand blanches. Release pressure from the ulnar artery and watch for color to return within 15 seconds, which suggests adequate collateral perfusion. 1

Can you inject a pearl into an arterial line?

Clinical pearl: Never inject anything into an arterial line. The elevated drug concentration in arteries and capillaries can cause severe ischemia and damage to the limb. 5
