It is important to try and become familiar with these pieces of equipment because they are often times relied upon heavily during a case. Some examples are listed below:<\/p>\n<ul>\n<li><strong><a href=\"http:\/\/www.stepwards.com\/?page_id=22102\">Using Ultrasound For Interventional Radiology Procedures<\/a>:\u00a0<\/strong>this is a very large topic however a video series that introduces how to use ultrasound for interventional radiology procedures is linked here.<\/li>\n<\/ul>\n<h5><span id=\"BASIC_TECHNICAL_SKILLS_RELEVANT_TO_NEUROINTERVENTIONAL_RADIOLOGY\"><span style=\"text-decoration: underline;\">BASIC TECHNICAL SKILLS RELEVANT TO NEURO<\/span><span style=\"text-decoration: underline;\">INTERVENTIONAL <\/span><span style=\"text-decoration: underline;\">RADIOLOGY<\/span><\/span><\/h5>\n<p>Trainees may have been exposed to some of these technical skills from other specialties, however they are also very useful to the field of NIR.<\/p>\n<ul>\n<li><strong><a href=\"http:\/\/www.stepwards.com\/?page_id=2919\">Suturing Basics<\/a>:\u00a0<\/strong>while this guide was initially made for those interested in surgery, the skills and techniques discussed are very useful for those in NIR as well.<\/li>\n<li><a href=\"https:\/\/www.stepwards.com\/?page_id=26503\"><strong>Performing a Pulse Exam<\/strong><\/a>: an important step before any trans-arterial intervention.<\/li>\n<\/ul>\n<h5><span id=\"START_UP_KITSTRAYS\"><span style=\"text-decoration: underline;\">START UP\u00a0 KITS\/TRAYS<\/span><\/span><\/h5>\n<p>These refer to the start up kits\/trays that the technicians will use to prepare for each neurointerventional radiology case.

Unlike most surgical specialties for NIR cases it is important to be familiar with how to scrub yourself into the case (this essentially involves putting on your gown and gloves by yourself in a sterile fashion). The general workflow for scrubbing into a case involves acquiring your gown\/gloves, opening them up, washing your hands, and then carefully putting on your gown, and then using your gown to put on your gloves in a sterile fashion.<\/p>\n<p>For more detailed reference please reference the <strong><a href=\"http:\/\/www.stepwards.com\/?page_id=24830\">dedicated page on how to scrub yourself into interventional radiology cases<\/a><\/strong>\u00a0which provides instructional videos as well.<\/p>\n<h5><span id=\"BASIC_TASKS_PRIOR_TO_THE_START_OF_A_CASE\"><span style=\"text-decoration: underline;\">BASIC TASKS PRIOR TO THE START OF A CASE<\/span><\/span><\/h5>\n<p>After scrubbing into a case there are often certain tasks that need to be done to prepare the equipment that is routinely used at the start of the case. This includes the following:<\/p>\n<ul>\n<li><strong><a href=\"https:\/\/www.stepwards.com\/?page_id=26382\">Organizing Sharps on the Back Table:<\/a>\u00a0<\/strong>an organized back table is important preparation prior to the start of a case. The linked page shows how to organize the table, and specifically the sharps, to help minimize the risk of an adverse event.<\/li>\n<li><strong><a href=\"https:\/\/www.stepwards.com\/?page_id=26376\">Flushing Arterial (Drip) Lines<\/a>:\u00a0<\/strong>most all neurointerventional radiology procedures will require at least one arterial drip line to run during the case (to protect against thromboembolic events). These arterial lines will need to be flushed and prepared prior to usage to prevent the introduction of air into the patient. The linked page shows how to flush these lines prior to use.<\/li>\n<\/ul>\n<h5><span id=\"BASIC_TECHNIQUES_AT_THE_START_OF_THE_CASE\"><span style=\"text-decoration: underline;\">BASIC TECHNIQUES AT THE START OF THE CASE<\/span><\/span><\/h5>\n<p>Once the case has begun here are some basic fundamental techniques to be aware of:<\/p>\n<ul>\n<li><strong><a href=\"https:\/\/www.stepwards.com\/?page_id=26369\">Filling Syringes<\/a>:\u00a0<\/strong>there is a specific technique employed when filling syringes (with saline, contrast, etc) for neurointerventional cases designed to prevent the injection of air. This linked page and video shows this technique.<\/li>\n<li><a href=\"https:\/\/www.stepwards.com\/?page_id=26390\"><strong>Handling Sharps<\/strong><\/a>: proper handling of sharp objects during a case is essential for provider and patient safety.<\/li>\n<li><a href=\"https:\/\/www.stepwards.com\/?page_id=26498\"><strong>Double Flushing<\/strong><\/a>: this is how to properly flush equipment that has been exposed to patient blood (to prevent showering the brain with thromboemboli)<\/li>\n<\/ul>\n<h5><span id=\"CLOSING_ACCESS_SITESSECURING_DEVICESAPPLYING_DRESSINGS_AT_THE_END_OF_A_CASE\"><span style=\"text-decoration: underline;\">CLOSING ACCESS SITES\/SECURING DEVICES\/APPLYING DRESSINGS AT THE END OF A CASE<\/span><\/span><\/h5>\n<p>At the end of cases it is important to make sure that access sites are closed, devices are properly secured, and that dressings are applied neatly and properly to the patient as needed. Not only is this what the patient and other providers will see, however these dressings also serve a medical purpose (limiting oozing\/bleeding, preventing infection, allowing for proper wound healing, etc). It is important to be comfortable and capable with dressing types listed below:<\/p>\n<ul>\n<li><strong><a href=\"http:\/\/www.stepwards.com\/?page_id=25042\">Closing Femoral Artery Access Sites (Angio-Seal Vascular Closure Device)<\/a>:\u00a0<\/strong>the linked device is one used very commonly to close femoral artery access sites.
