Öğe Carotid angioplasty and stenting in carotid artery stenosis: Neuroscience nursing implications(2010) Oran N.T.; Oran I.Stenosis of the internal carotid artery due to atherosclerosis can cause embolic stroke or cerebral ischemia, both of which may result in significant morbidity, mortality, and long-term disability. Although the endovascular technique with balloons and stents to relieve arterial (i.e., coronary) stenosis has allowed a nonsurgical approach to the management of atherosclerotic disease for many years, its use in carotid vessels has only recently gained popularity. In addition, improvements in endovascular access systems have extended the use of carotid angioplasty and stenting (CAS), especially since the advent of cerebral emboli protection devices. Nowadays, CAS is emerging as an intervention for high-risk surgical patients with high-grade carotid artery stenosis. Nursing care of these patients before, during, and after CAS is challenging. Patients and family need to be educated about the aim and consequences of the procedure and its complications. To care for these patients, the nurse must understand the techniques of CAS. The purpose of this article was briefly to review the etiology of stroke, the current treatments to relieve carotid stenosis, and the basic steps of CAS. The nursing management throughout the procedure, the patient preparation before the procedure, and most importantly, the postprocedure nursing care are discussed.

Thrombus related catheter removal occurred in two patients in control but no patients in the experiment group. Heparin locking six times a week was found to be effective in prolonging the mean of the first day where difficulty was experienced in aspiration. It also prevented any possible difficulty in catheter flushing. Increased locking frequency prevents any thrombus accumulation within the temporary catheter, while it has limited but significant preventive effect on thrombus accumulated around the catheter. © 2008 European Dialysis and Transplant Nurses Association/European Renal Care Association.Öğe Management of patients with malignant obstructive jaundice(Lippincott Williams and Wilkins, 2000) Oran N.T.; Oran I.; Memis A.Most patients with obstructive jaundice caused by primary pancreaticobiliary malignancies and metastatic disease cannot be cured by surgical resection when diagnosed. Biliary drainage in the management of obstructive jaundice therefore represents one of the most important issues in the palliative treatment of these patients. For more than 20 years, percutaneous transhepatic biliary drainage procedures have allowed a nonsurgical approach to the management of malignant biliary obstruction. Improvements in radiologic access systems have extended the use of the percutaneous biliary approach, especially since the advent of metallic stents. Nursing care of these patients before, during, and after the percutaneous biliary intervention is challenging. Patient and family need to be educated about the aim and consequences of the procedure as well as its complications. To care for these patients, the nurse must understand the techniques of percutaneous transhepatic biliary drainage. The purpose of this article is briefly to review the etiology of biliary obstruction, the current treatments to relieve obstructive jaundice, and the basic steps of biliary intervention techniques. The nursing management throughout the procedure, the patient preparation before the procedure, and most importantly, the postprocedural nursing care are discussed.Öğe Percutaneous chordotomy for managing cancer pain.(2001) Oran N.T.Pain is a problem frequently encountered by patients with cancer. For more than 30 years, the percutaneous chordotomy procedure has been a nonpharmacological approach to the management of intractable cancer pain. Nursing care of patients before, during, and after the percutaneous chordotomy procedure is challenging. Patients and their family members need to be educated about the intent and outcomes of the procedure, as well as its complications. The purpose of this article is to review the theoretical aspect of pain perception and outline the anatomical background and basic steps of the percutaneous chordotomy procedure. Preoperative patient education and preparation, intraoperative nursing interventions, and postoperative patient care are discussed.Öğe Percutaneous Transthoracic Needle Biopsy for Diagnosis of Thorax Malignancies: Nursing Perspective(2007) Oran N.T.Lung nodules/masses under suspicion of malignancy are a clinical problem frequently encountered in patients with or without known cancer. Percutaneous transthoracic needle biopsy (PTNB) has been a minimal invasive diagnostic approach to patients with cancer in whom routine clinical and radiological diagnostic efforts have failed. Nursing care of patients before, during, and after the PTNB is not complex, but it is a new concept. Patients and their family members need to be educated about the intent and outcomes of the procedure, as well as its complications. The purpose of this article is to review the theoretical aspect of the procedure and outline basic steps of computed tomography-guided PTNB. Preoperative patient education and preparation, intraoperative nursing interventions, and postoperative patient care are discussed. © 2007 American Radiological Nurses Association.
