Heart Catheterization Using Magnetic Resonance Imaging (MRI) Fluoroscopy and Passive Guidewires

Heart catheterization is a minimally invasive procedure used to gauge pressure into specific heart cavities. Heart catheterization uses X-ray guidance, which involves radiation exposure and does not allow heart catheterization to be visible soft tissue. For many years, real-time magnetic resonance imaging fluoroscopy has been the industry's preferred method to guide right heart catheterization at the NIH clinical center. We will use guidewires during otherwise standard MRI catheterization of the right side of the heart through veins and of the left side of the heart through the aorta in this protocol. If possible, we will begin performing systematic MRI guidewire heart catheterization without using X-ray as appropriate in the second phase of the protocol. During MRI catheterization tailored to the patient's situation, we will see how the heart responds to hemodynamic provocation.

Cardiac Output Assessment in Pulmonary Hypertension Patients Undergoing Right Heart Catheterization

This observational study was designed to compare cardiac output measurements between Direct Fick method, Indirect Fick method, and Thermodiluction in pulmonary hypertension patients undergoing right heart catheterization. Patients will be evaluated for RHC by a Swan-Ganz catheter with the right internal jugular vein ultrasound-guided cannulation and cardiac output using the three above-mentioned protocols.

Predictors and Outcomes of Time to Hemostasis Post Trans-femoral Cardiac Catheterization: a Multicenter Cohort Study

In several acute and critical care settings, removing femoral sheaths and handling related problems following percutaneous coronary intervention may be helpful. Therefore, following catheterization procedures, reviewing the predictors of required hemostasis at the time of trans-femoral sheath removal is a key step toward preventing access site complications. This report will be conducted in six Cardiac catheterization units representing governmental and private hospitals.

A Randomized Controlled Trial Comparing In-line Ultrasound Guided Subclavian Vein Catheterization With or Without Needle Guide.

OBJECTIVES The main aim is to determine if the addition of a needle guide in ultrasound-guided catheterization of the subclavian vein using the long-axis approach with an in-plane needling technique. OUTCOMES Primary outcome is expected to be the number of CVC insertions with > 1 skin puncture. During the investigation, the needle guide's reliability was determined with a questionair to the operators. 2nd group's results relate to the frequency of mechanical disorders, 28% of the insert-time when the needle is visible on the ultrasound U. S. screen, 3 times to successful vessel punction, 2 percent of the needle inserts, 3 time to successful vessel punction, 3 time to successful vessel punction, 3 time to successful vessel punction, 31% of failed catheterizations, 6 the possibility of failed catheterizations.

Investigation of the Effect of Jet Lidocaine and Ice Application on Pain and Anxiety in Peripheral Venous Catheterization: A Randomized Controlled Study

PTR specialists and six nurses are among the study's principals; on the other hand, the PTR clinic, on the other hand, has a 15-bed capacity and provides services with one PTR specialist and six nurses; PVC specialists and six nurses, on the other hand, are hospitalized in Gumushane State Hospital between the dates of the study; All patients who are hospitalized in the Internal Medicine and PTR clinics need PVC for their treatment plan; PTR specialists, on the study; In order to monitor individual differences in pain and anxiety, each patient would create their own control group in order to monitor individual differences in pain and anxiety. The other extremity vein will be used when making subsequent PVC applications after the cephalic vein for the first attempt is randomly determined. The peripheral venous catheter's side grip sections of the peripheral venous catheter will be brought to the horizontal position by wearing gloves. With the tapered side of the needle facing up, the catheter will be held between the thumb and forefinger. The catheter will be held at 30-45,u00b0 to the skin, about 1 cm below the area where the vein is supposed to be visible, and the vein will be visible, with the vein being traced. It will be tested whether blood is coming to the blood stopper valve, and if there is blood, the catheter will continue to be advanced in the vein. The clinical nurse with the Wong-Baker Faces Pain Rating Scale will determine the severity of pain related to the PVC application after catheter introduction. Without moving the catheter in the vein, the tourniquet will be loosened with the inactive hand, fixed temporarily with a small patch, the catheter's needle will be removed and the catheter's cap will be closed. Patients' pain and anxiety levels related to PVC application will be tested within 1 minute following catheterization, with VAS-A and VAS-P. Implementation steps 1-7 of the Control Group will be completed by the Intervention group-I PVC Application Steps. Since 0. 3 ml of lidocaine solution or 3 mg of total dose would not cause a problem in terms of drug toxicity, a problem in terms of drug toxicity will not exist; 0. 3 ml 1% lidocaine solution or 3 mg of total dose will not pose a problem; 0. 3 ml 0. 1 lidocaine solution or 3 mg of total dose will not pose a problem; 0. 1 ml 1% lidocaine solution or 3 mg of 0. 2 0. 1 0. 3 0. 4 0. 1 0. 2 0. 1 0. 6 0. 4 mg of total dose will not pose no toxicity will be administered with drug toxicity will not pose no toxicity will not toxicity will not pose no problem will be applied with 0. 2 0. 1 0. 1 1. 06 0. 05 will be used with 0. 3 0. 1 0. 2 0. 1 0. 05 0. 1 0. 2 0. 2 0. 1 0. 3 0. 4 0. 1 0. 05 will not pose no issue in terms of drug 0. 1 0. 6 0. 2 0. 2 0. 3 1. 11 0. 1 0. 1 0. 2 0. 4 0. 2 0. 4 0. 2 0. 1 0. 1 1. 2 0. 1 The Jet unit will be lifted and the skin will be announced after waiting for 5 seconds. Implementation of Initiative Group-II PVC Application Steps will be carried out, according to Initiative Group-II PVC Application Steps. The Process Will Be Completed by the Control Group's 8-21 application steps. Visual Analog Scale Score for Anxiety, Visual Analog Scale Score for Pain, and Wong-Baker Faces Pain Rating Scale Score were among the study's dependencies that were tested. Independent variables: 0. 3 ml Jet lidocaine application before peripheral venous catheterization 1 minute ice application before peripheral venous catheterization The results will be evaluated in the SPSS package version.
