X-ray<\/h2>\n\n\n\n
It is an easily accessible<\/strong> resource in hospitals, either in the radiology department or at the bedside. <\/p>\n\n\n\n The catheter tip is located using anatomical references in the image.<\/p>\n\n\n\n <\/p>\n\n\n\n <\/p>\n\n\n\n With this method, the cavoatrial junction cannot be seen and is therefore subjective<\/strong>. <\/p>\n\n\n\n This is shown in the study \u201cOptimizing the patient positioning for PICC line tip determination\u201d (Harako ME1<\/sup>, Nguyen TH, Cohen AJ), which proves that different professionals might interpret the catheter tip location in an X-ray quite differently. <\/strong><\/p>\n\n\n\n The length of the Superior Vena Cava can vary considerably from one patient to another: between 4.4 and 10 cm, and this is only one of the anatomical structures which can change from one patient to another. <\/p>\n\n\n\n <\/p>\n\n\n\n This method, which involves X-rays, is mainly used in the interventional radiology<\/strong> department. Performing a real-time X-ray gives a continuous, live image<\/strong> of the patient. Catheter insertion can be visualised and the catheter tip can be located, to make sure it is in the right position.<\/p>\n\n\n\n Fluoroscopy is considered a sufficiently accurate method<\/strong> to position the central catheter. However, it is rather expensive, in terms of technology, equipment, training and logistics.<\/p>\n\n\n\n Its use is recommended only in special cases as it involves radiation exposure that should be avoided (INS).<\/p>\n\n\n\n <\/p>\n\n\n\n <\/p>\n\n\n\n There are 2 types of echocardiography:<\/p>\n\n\n\n <\/p>\n\n\n\n Transesophageal echocardiography (TEE) can be very uncomfortable <\/strong>for the patient as it requires an upper endoscopy to place the probe close to the heart from inside the esophagus<\/strong>. Additionally, it necessitates the use of an operating room<\/strong> and trained personnel<\/strong>, limiting its application to very few patients.<\/p>\n\n\n\n <\/p>\n\n\n\n Compared to TEE, transthoracic echocardiography (TTE) is non-invasive<\/strong> and relies more on the technique used and the expertise of the professional. The ultrasound probe is placed on the patient’s chest at the level of the sternum to visualize the four cardiac chambers<\/strong>.<\/p>\n\n\n\n To accurately determine the position of the central catheter tip using echocardiography, a high level of knowledge<\/strong> in echocardiographic imaging<\/strong> is required.<\/p>\n\n\n\n <\/p>\n\n\n\n There is no standardization of techniques; however, echocardiography is currently the most accurate method<\/strong> for locating the tip of a central line, surpassing the precision of fluoroscopy.<\/strong><\/p>\n\n\n\n Regarding cost, an echocardiograph comes at a high price<\/strong>, though far from the investment required for a fluoroscope.<\/p>\n\n\n\n Both types of echocardiography are safe <\/strong>techniques but TEE <\/strong>is the more precise of the two.<\/p>\n\n\n\n <\/p>\n\n\n\n Although it is amortised in a relatively short period of time, this system involves a significant initial cost which is expensive compared to, for example, a single X-ray. <\/p>\n\n\n\n As with any ECG system, if it is located near other electrical devices, the image of the traces may contain artifacts. <\/p>\n\n\n\n Using this method, we place the electrodes on the patients body<\/strong> in the same way as for any standard ECG monitoring.<\/p>\n\n\n\n <\/p>\n\n\n\n The intracavitary electrode<\/strong> (the red or yellow clip is connected to the catheter) allows the catheter tip to be accurately located thanks to the interpretation of the P-wave.<\/p>\n\n\n\n <\/p>\n\n\n\n <\/p>\n\n\n\n In fact, the most appropriate technique to locate the tip of a PICC is ECG. It is due to the following reasons:<\/p>\n\n\n\n <\/p>\n\n\n\n Attempting to locate the tip of a PICC using an incorrect method can have negative consequences for both the professional and the patient. In the case of PICC, there is a demonstrated risk of:<\/p>\n\n\n\n <\/p>\n\n\n\n <\/p>\n\n\n\n The reference guidelines on vascular access leave no doubt: it is essential to position and correctly locate the tip of a PICC. Otherwise, healthcare professionals risk encountering complications that can jeopardize the ongoing treatment and even the patient’s health. To minimise these risks and accurately locate the tip of a PICC, four different methods can […]<\/p>\n","protected":false},"author":16,"featured_media":49223,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"_et_pb_use_builder":"off","_et_pb_old_content":"","_et_gb_content_width":"1080","footnotes":""},"categories":[844],"tags":[156,1043,1045,1044],"class_list":["post-2139","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-vascular-access","tag-ecg","tag-echocardiography","tag-fluoroscopy","tag-x-ray"],"acf":[],"_links":{"self":[{"href":"https:\/\/campusvygon.com\/global\/wp-json\/wp\/v2\/posts\/2139","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/campusvygon.com\/global\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/campusvygon.com\/global\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/campusvygon.com\/global\/wp-json\/wp\/v2\/users\/16"}],"replies":[{"embeddable":true,"href":"https:\/\/campusvygon.com\/global\/wp-json\/wp\/v2\/comments?post=2139"}],"version-history":[{"count":20,"href":"https:\/\/campusvygon.com\/global\/wp-json\/wp\/v2\/posts\/2139\/revisions"}],"predecessor-version":[{"id":50461,"href":"https:\/\/campusvygon.com\/global\/wp-json\/wp\/v2\/posts\/2139\/revisions\/50461"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/campusvygon.com\/global\/wp-json\/wp\/v2\/media\/49223"}],"wp:attachment":[{"href":"https:\/\/campusvygon.com\/global\/wp-json\/wp\/v2\/media?parent=2139"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/campusvygon.com\/global\/wp-json\/wp\/v2\/categories?post=2139"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/campusvygon.com\/global\/wp-json\/wp\/v2\/tags?post=2139"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}![\"How](\"https:\/\/campusvygon.com\/global\/wp-content\/uploads\/sites\/10\/2021\/03\/How-to-locate-the-tip-of-a-PICC-X-Ray.jpg\")
