Preventing Retained Central Venous Catheter Guidewires
Whole central venous catheter (CVC) guidewire retention is an iatrogenic error, with an incidence of 1:3,167, a morbidity of 4-53%, mortality of 4-6% and is a never event. Since 2011, health policy has mandated that all hospitals must implement national safety guidance to prevent this error, …

Midline Catheter Usage in the Neonatal Population
… Literature reviewed demonstrated that a midline catheter (MC) was an option for a VAD with neonatal populations requiring antibiotic therapy more than 48 hours. MCs offer fewer complications compared to the peripheral intravenous (PIV) device. The objective of this project is to reduce the amount …

Electromagnetic tracking and steering for catheter navigation
… use of DC magnetic fields for the actuation of catheter devices with permanently magnetised distal attachments is investigated. Catheter models formed from various materials and magnetic tip formations are used to examine the usefulness of relatively low power and compact electromagnets. The …

Catheter for endoscopic magnetomotive optical coherence tomography
In this thesis, a catheter design is proposed for endoscopic magnetomotive optical coherence tomography (MM-OCT). Magnetomotive optical coherence tomography is a novel technique which uses targeted magnetic contrast agents for contrast enhancement of OCT imaging. In MM-OCT, microspheres and …

Catheter based magnetic resonance compatible perfusion probe
Neurosurgeons are using a thermal based technique to quantify brain perfusion. The thermal diffusion probe (TDP) technology measures perfusion in a relatively small volume of brain tissue. The neurosurgeon chooses the specific brain location and probe placement based on their clinical concern. When …

Improving Compliance in the Use of Catheter Kit Supplied Hand Sanitizer Prior to the Insertion of an Indwelling Urinary Catheter
… prior to insertion of an indwelling urinary catheter. This performance improvement project aims to educate all OR staff nurses on the practice of hand hygiene prior to the insertion of an indwelling urinary catheter by using the hand sanitizer included in the sterile catheter insertion kit. …

Prevention of catheter-associated infections : chlorhexidine vs unmedicated solutions
… around 45-56% are directly related to a urethral catheter (Loveday et al., 2014). To avoid unnecessary UTIs caused by urethral catheterisations, meatal cleaning is recommended prior to insertion to prevent the introduction of bacteria within the urinary tract (NICE Guidelines, 2014). This …

Implementing Ways to Reduce Catheter-associated Urinary Infections (CAUTIs)
… Gluconate (CHG) bathing for patients with Foley catheter. Besides, nurses’ adherence to policy and procedures for urinary catheter management including early removal of unnecessary Foley are reevaluated. This project aims to reduce CAUTI occurrence by 41% by December, 31<sup>st</sup>, 2016. …

Parameters and algorithms to evaluate cardiac mechanics by conductance catheter
… Specifically, we describe the conductance catheter and its use for the measurement of dyssynchrony. At the end of the Section 1, we propose a new set of indexes to quantify the dyssynchrony that are studied and validated thereafter. In Section 2 we describe the studies carried out in this …

The prevention and diagnosis of central venous catheter-related infection
… and specific genotypes implicated in catheter colonisation. In addition, phenotypic and genotypic typing techniques were assessed for their ability to characterise strains of CoNS recovered from 33 patients who developed catheter-related bloodstream infection (CR-BSI) on a bone marrow …

Immobilization and Catheter Guidance for Breast Brachytherapy Using Patient-Specific Templates
… are needed. The procedure involves insertion of catheters in the tumor site, which, in current practice, is prone to clinically significant error. In order to improve on contemporary catheter placement accuracy, integration of pre-operative imaging, supplemented by computerized surgical planning …

Biocompatibility assessment of a sol-gel modified electrospun ventricular shunt catheter
… this condition involves the insertion of a shunt catheter to bypass the blockage and allow the CSFto flow from the ventricles, thus avoiding a possible build-up of intracranial pressure. Such catheters, which are commonly made frommedical grade silicone, are known to be affected by mechanical …

The source, cost and prevention of central venous catheter-related infection
Central venous catheters have become an integral part of patient management however they are associated with many complications including infection. Despite efforts being made to reduce the incidence of such infect ions the problem continues to increase and has resource implications for the Health …

Assessment of catheter-manometer systems used for invasive blood pressure measurement
… of blood pressure using a fluid-filled catheter and an electromechanical transducer is widely accepted in clinical practice. However, errors associated with the measurement are often not appreciated and these catheter-manometer systems are frequently unable to accurately reproduce …

Design of an Ultrasound-Guided Steerable Robotic Catheter for Aortic Interventions
… in the femoral artery to insert a steerable catheter, and real time x-ray imaging provides guidance as the surgeon maneuvers it to a target site. A variety of interventional devices, such as stents, grafts, and coils can then be delivered through a catheter to reach the treatment area. While …
