9 Ultrasound Guided Vascular Access
Vascular access is an important procedure for clinicians to master. Chronic medical conditions, intravenous drug use, and obesity can all make placements of vascular catheters in central and peripheral veins challenging and time-consuming. External landmarks have traditionally guided the placement of the needle for the performance of central venous catheterization. The proximity of such structu...
متن کاملUltrasound-guided central venous access
Central venous catheterization is a critical component of management for the critically ill patient in the operating room and intensive care unit. When using ultrasound techniques for central venous access, access is achieved with fewer attempts, a reduced incidence of carotid artery punctures or 'hits', an increased success rate, and a decreased duration of procedure compared to the traditiona...
متن کاملUltrasound-guided central venous access.
HYPOTHESIS Real-time ultrasound guidance should increase the success rate and lower the complication rate of central venous access in patients with relative contraindications to having the procedure performed. DESIGN Prospective case series. SETTING A community-based tertiary care hospital. PATIENTS Fifty-two patients were studied. Relative risks to central venous catheter insertion inclu...
متن کاملUltrasound-guided cannulation of hemodialysis access
Because hemodialysis therapy cannot be performed without the cannulation of a vascular access, establishing a well-functioning vascular access is crucial. Recently, the number of patients with difficult arteriovenous (AV) fistula cannulation has increased due to changes in the epidemiology of the dialysis population. To address this issue, indications for real-time ultrasound-guided techniques ...
متن کاملUltrasound-guided peripheral intravenous access in the intensive care unit.
PURPOSE Central venous catheters continue to be a popular means of maintaining vascular access in surgical intensive care units despite well-described complications. With edema, obesity, and difficult to visualize veins potentially affecting the surgically ill, inability to obtain peripheral intravenous (PIV) access may hinder the clinician's ability to avoid the use of central lines. With ultr...
