Changes of Oxygen Saturation in Inferior Vena Cava (IVC) in Patients During and After High Risk Abdominal Surgery and Relationship to the Outcome
Summary
Tissue hypoxia is one of the most important factors leading to the development of multiorgan failure. Patients presenting for emergent major abdominal surgery might suffer from organ hypoperfusion. Thus, early detection of the imbalance between oxygen supply and demand may improve the outcome. The investigators believe that hypoperfusion of the abdominal organs will cause a decrease of the saturation in the hepatic vein and in the IVC.

Medical and Biotech [MESH] Definitions
Catheterization, Central Venous
Placement of an intravenous catheter in the subclavian, jugular, or other central vein for central venous pressure determination, chemotherapy, hemodialysis, or hyperalimentation.
Abdominal Wound Closure Techniques
Methods to repair breaks in abdominal tissues caused by trauma or to close surgical incisions during abdominal surgery.
Retinal Vein
Central retinal vein and its tributaries. It runs a short course within the optic nerve and then leaves and empties into the superior ophthalmic vein or cavernous sinus.
Portal Vein
A short thick vein formed by union of the superior mesenteric vein and the splenic vein.
Catheterization, Peripheral
Insertion of a catheter into a peripheral artery, vein, or airway for diagnostic or therapeutic purposes.
Clinical Trials
To test the hypothesis that approaching the internal jugular vein with the needle bevel down would produce less injury to the vessel wall compared to the bevel up approach during central v...
To evaluate the effect of a 2-stage approach to the internal jugular vein when performing a central venous catheterization compared to the traditional one stage approach on the incidence o...
Radial Optic Neurotomy in Central Retinal Vein Occlusion : a Randomized Trial
Natural evolution of severe central retinal vein occlusion with low visual acuity is very poor. A randomized clinical trial will compare troxerutin and platelet anti-aggregating agents (dr...
Estimation of Internal Jugular Vein Central Venous Pressure (CVP) by Ultrasound
Objectives: 1. To study the validity and reliability of estimation of the central venous pressure by measurement of internal jugular vein size using 2-dimensional ultrasound....
Central Vein Occlusion Study (CVOS)
To determine whether photocoagulation therapy can help prevent iris neovascularization in eyes with central vein occlusion (CVO) and evidence of ischemic retina. To assess whether grid-pa...

Ultrasound-guided supraclavicular subclavian vein catheterization: A novel approach in children.
The subclavian vein (SCV) is often the preferred site for long-term central venous catheterization in children. It has many advantages over the internal jugular vein. But with the classical landmark t...
Massive hydrothorax following subclavian vein catheterization.
ABSTRACT: Since the introduction of central venous catheterization for monitoring of the venous pressure, fluid infusion and hyperalimentation, the literature has been full of serious life-threatening...
An iatrogenic complication of internal jugular vein catheterization for hemodialysis.
BACKGROUND: Central venous catheterization is increasingly performed as a temporary vascular access for hemodialysis therapy in developing countries and it can be associated with serious complications...
To determine prevalence of central vein stenosis following catheterization with double-lumen temporary catheters, we performed color Doppler sonography in 100 consecutive patients. We detected central...
We present a case of the successful repair of an iatrogenic central vein lesion using a videothoracoscopic approach. The confluence of the right innominate vein and the superior vena cava was perforat...
