Conventional tracheostomies have been used for many years to deliver oxygen with the patient breathing spontaneously or in conjunction with positive pressure ventilators. The insertion of a transtracheal catheter specifically to deliver oxygen, however, dates only from Heimlich's studies published in 1982.' He showed that in dogs and man a normal oxygen saturation could be maintained by the del...
Percutaneous endoscopic gastrostomy (PEG) tube placement serves as a well-tolerated and efficacious technique for long-term enteral access in patients with medical conditions precluding oral food intake. The nutritional optimisation of patients with oral cancer is mostly achieved via PEG tube placement. However, certain special situations, such as pregnancy and the immediate post-partum period,...
Hypothesis / aims of study Tibial neuromodulation (TNM) is a clinically used therapy for patients with refractory, idiopathic overactive bladder [1]. TNM is currently delivered percutaneous using a needle electrode. Therapy sessions are commonly 30 minutes of stimulation once per week. There are questions regarding how often therapy should be delivered as well as optimal clinical and patient sc...
OBJECTIVES To validate the feasibility of labeling Clostridium novyi-NT (C.novyi-NT) anaerobes with iron-oxide nanoparticles for magnetic resonance imaging (MRI) and demonstrate the potential to use MRI to visualize intra-tumoral delivery of these iron-oxide labeled C.novyi-NT during percutaneous injection procedures. MATERIALS AND METHODS All studies were approved by IACUC. C.novyi-NT were l...
The aim of this study was to determine the efficacy of pectin solution, which increases the viscosity of liquid nutrient, for prevention of gastro-esophageal reflux in comparison with half-solid nutrient. The subjects were 10 elderly patients undergoing percutaneous endoscopic gastrostomy feeding. Twenty-four-hour esophageal multichannel intraluminal impedance and pH testing was performed durin...
Significant progress has been made in the field of cardiovascular gene therapy over the past decade. Animal models of human disease have helped in identifying potential therapeutic genes and have also assisted in the evaluation of an ideal vector. A number of percutaneous catheter systems have been used in animal models with limited success. Stents represent an attractive alternative for locali...
BACKGROUND Although patients may experience a quick recovery followed by rapid discharge after percutaneous coronary interventions (PCIs), continuity of care from hospital to home can be particularly challenging. Despite this fact, little is known about the experiences of care across the interface between secondary and primary healthcare systems in patients undergoing PCI. AIM To explore how ...
