Get the veins real fat with IV fluid, try putting the patient head down, try pulling down on the ipsilateral arm, try turning the j-wire through 90 degrees four times, try turning the patients neck one way and if that doesn’t work — the other way, try using the other (non j-shaped) end of the wire — in the 21st century this is equally flexible as the j-end — it was not always so.<\/p>\n

Zone A represents the lower SVC and upper RA. In this zone CVCs placed from the left side are likely to lie parallel to the vessel walls. However, a part of this zone lies within the RA and therefore within the pericardial reflection. This may represent a necessary compromise for left-sided CVCs to ensure they lie parallel to the vessel wall. Right-sided CVCs in this zone, however, should be pulled back to zone B. The azygous vein junction with the SVC lies within this zone and catheters may pass into this system. Zone B represents the area around the junction of the left and right innominate veins and the upper SVC. This is a suitable area for CVCs placed from the right side, however left-sided CVCs will enter this area at a steep angle (see Fig. 4) and are at risk of abutting the lateral wall of the SVC and should ideally be advanced into zone A. Zone C represents the left innominate vein proximal to the SVC. CVCs in zone C are probably suitable for short-term fluid therapy and CVP monitoring, but not for inotrope infusions or long-term use. The safety of this site has been questioned.14 Instructions accompanying the packaging of CVCs state that it is negligent to site the CVC with the tip in the RA. This is because of the potential risk of pericardial tamponade if the CVC tip erodes through the vessel wall below the pericardial reflection. The upper limit of the pericardial reflection cannot be seen on CXR, but anatomical studies have shown that it is very unlikely to extend above the level of the carina \"\"<\/a><\/p>\n

There is literature out there to support you (especially supporting the notion when experienced clinicians use good technique, good clinical judgment, and discrimination- Puls LE.; Twed\u00a0 C; Hunter J; Langan E, Crane M. <\/em> Confirmatory Chest Radiographs after Central Line Placement: Are They Warranted?<\/strong> Southern Medical Journal 2003; 96(11):1138-1141.). However a relatively recent reviews point out the relatively high rate of catheter tip malposition (Catheter tip malposition occurs in up to 14% of cases of IJ insertion and 11% of subclavian vein (Ruesch S, Walder B, Tramer M.

<\/span>Trendelenberg for Line Placement<\/span><\/h3>\n

(Emergency Medicine Journal 2005;22:867-868) Conclusion: Increasing the degree of Trendelenburg tilt increases the lateral diameter of the IJV. Even a 10\u00b0 tilt is effective. The cumulative effect of tilt (that is, the effect of the previous angle) is not significant. Ultrasound guided cannulation is ideal, but in its absence Trendelenburg tilt will increase IJV diameter and improve the chance of successful cannulation. While 25\u00b0 achieved optimum distension, this may not be practical and may be detrimental (for example, risk of raised intracranial pressure).<\/p>\n

Subclavian is 3 times less infection prone than IJ and much lower than femoral (CAn J Anesth 2006;53(5):524)<\/p>\n

A persistent left superior vena cava (LSVC) that is not associated with other congenital heart defects is found in 0.3\u00960.5% of the population. During embryological development, venous return from the head and arms occurs via the left and right cardinal veins. At 8 weeks gestation, the caudal portion of the left cardinal vein degenerates, leaving the right cardinal vein to develop into the right superior vena cava. Failure of regression of the left cardinal vein results in a persistent LSVC (2). The LSVC courses in the anterior aspect of the aortic arch draining into the right atrium via the coronary sinus, which becomes dilatated (3). Unless associated with other anomalies, this condition does not cause any harmful hemodynamic effects (1). The existence of a persistent left superior vena cava is suggested by an X-ray that implies aortic cannulation in the face of an uncomplicated venous puncture and no evidence to support arterial cannulation.<\/p>\n

The Wire<\/h4>\n

Safe use and handling of guidewires for central venous cannulation requires an understanding of the structure and physical characteristics of the wires. Monaca et al.6 have recently described the structure of a commonly used guidewire. According to their detailed description the guidewire consists of an inner single filament wire core and a surrounding coiled wire-cover. The latter is designed as a helix of stainless steel to form a tunnel for the inner wire and provides elastic properties. Apart from the two ends of the guidewire where the outer spiral is welded to the inner wire, there is no further point of attachment between the core and the outer wire. The typical J-shaped curvature is achieved by flattening the round core to a thickness of 0.1 mm wire at approximately 2.5 cm from the tip. This structure provides increased flexibility at the J-shaped tip. However it becomes an area of structural weakness at the junction of the rounded and flattened segments, which can lead to potential breakage.<\/p>\n

<\/span>Alternative approach to supraclavicular<\/span><\/h3>\n

\"\"<\/a><\/p>\n

Proposed (left) and traditional (right) supraclavicular approach techniques. Place a needle tip at the clavisternomastoid angle, then direct the needle 10\u00b0 medially from the sagittal plane and 35\u00b0 posteriorly from the coronal plane (that is to say, physician’s hand moves 10\u00b0 laterally and 35\u00b0 anteriorly from the skin entry point). Keep the bevel of an introducer needle and the J-tip of a guidewire heading to the medial side (arrow) to prevent ipsilateral axillary vein placement of catheter. In the original description of the supraclavicular approach by Yoffa (6<\/a>), the needle directs at an angle of 45\u00b0 from the sagittal plane and 15\u00b0 anteriorly from the coronal plane. SCM: the sternocleidomastoid muscle, IJV: the internal jugular vein, SCV: the subclavian vein, IV: the innominate vein.<\/p>\n

Proper Position For Femoral Vein Access<\/strong> If you are attempting to cannulate the femoral vein without the aid of an ultrasound machine, proper positioning of the leg can greatly enhance your chance of success. A recent study of health volunteers revealed that the femoral vein cannulation in adults is increased by placing the leg in abduction and external rotation.The mean percentage of the femoral vein accessible with the leg in external rotation\/abduction was greater than with the leg straight. This simple position change not only increased the mean diameter of the vein, it prevented the vein from being directly posterior to the artery.<\/p>\n
