In the case of larger caliber veins, a suture around the incision, rather than ligature, allows maintenance of blood flow, avoiding thrombophlebitis Figure 4.

Among the non-infectious complications recorded at our institution, there were 27 2. Song L, Li H. Bloodstream infections Diagnosis of bloodstream infections BSI in patients with long-term catheters is still a serious challenge.

Peripherally inserted central catheters: Needle inserted in the medial direction, below the clavicular branch of the sternocleidomastoid muscle; C Infraclavicular puncture of the subclavian vein, acessso entry between the medial and lateral thirds of the clavicle; D Puncture of the femoral vein medial of caesso site where the femoral arterial pulse is palpated.

The most important complications of PICCs are: The risk of bloodstream infection in adults with different intravascular devices: Now and then, the history of parenteral fluid administration.

These authors suggest that infected catheters should be removed in all patients with positive blood cultures, primarily if there is no improvement in fever within 48 h of appropriate administration of antibiotics.


Int J Lab Hematol. The greater incidence of superficial venous thrombosis in the cephalic vein is due to the anatomic characteristics of this vessel, such as smaller diameter in relation to the uugular of the catheter, lower number of tributaries, and more perpendicular insertion into the axillary vein Figure 6.

These catheters are not tunneled, but they offer long duration and the tip is maintained in a central position. Access to the venous system by puncture was pioneered by the French military surgeon Robert Aubaniac, who described the technique in Extrusion of the port Dehiscence of the skin with exposure of the port can be a result of an infection, but may also be caused by necrosis of skin, which can adhere to the port if there is insufficient subcutaneous tissue over the device.

There are two main types of semi-implantable catheters: CA Cancer J Clin. Since then there has been constant evolution in access technique and infusion devices. Methods This was a prospective, non-randomized study, conducted from February to November In such cases, the port pocket can be created more superficially, within the adipose plane, leaving subcutaneous tissue a minimum of 2 cm deep over the device.

When a catheter becomes obstructed, it is necessary to initiate the appropriate drug-based jjgular with thrombolytics, attempting to reduce the degree of catheter obstruction. InRobert Boyle and inRichard Lower described blood transfusions from animals to humans.

Ultrasound-guided and fluoroscopy-positioned PICC placement had a low incidence of complications, reduced infection rates, and proved safe and effective in cases of difficult vascular access. Em estudo reunindo 3. The venous path to the atrium is straighter on the right, which is why this side is preferred for insertion. In our patient sample there were five cases of catheter infection leading to removal because of the principal agents identified: Estudo prospectivo randomizado conduzido por Hoffer et al.


Os pacientes foram tratados com stents revestidos. The port pocket should be created in site that is firm and is distant from areas in which the skin has lost integrity, such as result from stoma, radiodermatits, or ulcerous tumoral lesions.

According to Dawson, the ideal puncture zone, indicated with green, is approximately 12 cm from the medial epicondyle, where the basilic vein is most superficial in relation to the plane of the skin. This procedure earned him the Nobel prize for medicine and introduced an alternative option for central venous access via a peripheral access.

Investigation of a malfunctioning catheter begins by checking the puncture. Os cateteres implantados foram de calibres 7Fr 17 casos e 12Fr 3 casos.

Eur J Surg Oncol. Negative pressure opens the valve, allowing blood to be drawn. The technique described by Aubaniac involved a medial access, guiding the puncture laterally and inferiorly in the direction of the fossa adjacent to the sternum.

Journal List Cetral Vasc Bras v. AEZ Ujgular geral pelo estudo: Peripherally inserted central catheters with proximal and distal valves were introduced to the market with the aim of reducing catheter occlusions by preventing blood backflow. Segundo estudo de Liem et al.
