Correlation Between External Jugular Venous and Central Venous Blood Oxygen Saturation in Patient Under General Anesthesia

2019-07-16 10:38:34 | BioPortfolio


After installation of central venous catheter in patients under general anesthesia, paired sample of central venous blood and right external jugular venous blood will be collected and send to central laboratory for blood gas analysis. Correlation between central venous blood and right external jugular venous blood oxygen saturation will be determined as primary outcome.


All patients undergoing surgery under general anesthesia and superior vena cava central venous catheter installation anticipated are eligible. Immediate after central venous installation, 1 ml of venous blood sample is taken from right external jugular vein and central venous catheter and send for blood gas analysis. Correlation between central venous blood and right external jugular venous blood oxygen saturation and partial pressure of carbon dioxide will be determined and prediction equation for central venous saturation is created.

Central Venous Saturation (ScvO2) Monitoring in Pediatric Patients Undergoing Cardiac Surgery

Children (ages 0-12) that have heart surgery are often at a high risk of developing complications and have to be continuously monitored. Part of the routine care at UCLA includes using a m...

Cerebral-tissue Oxygen Balance Affected by Diabetes Mellitus

The brain has high oxygen extraction, thus the regional cerebral tissue oxygen saturation (rSO2) is lower than the central venous oxygen saturation (ScvO2). We hypothesized that diabetes w...

Association of Central Venous Oxygen Saturation Variability and Mortality in Hemodialysis Patients.

Central venous oxygen saturation (ScvO2) is correlated with cardiac output. In most patients, ScvO2 declines during hemodialysis (HD) due to factors such as reduced preload, myocardial stunning, and i...

Medical and Biotech [MESH] Definitions

Placement of an intravenous catheter in the subclavian, jugular, or other central vein for central venous pressure determination, chemotherapy, hemodialysis, or hyperalimentation.

The determination of oxygen-hemoglobin saturation of blood either by withdrawing a sample and passing it through a classical photoelectric oximeter or by electrodes attached to some translucent part of the body like finger, earlobe, or skin fold. It includes non-invasive oxygen monitoring by pulse oximetry.

The blood pressure in the central large VEINS of the body. It is distinguished from peripheral venous pressure which occurs in an extremity.

Impaired venous blood flow or venous return (venous stasis), usually caused by inadequate venous valves. Venous insufficiency often occurs in the legs, and is associated with EDEMA and sometimes with VENOUS STASIS ULCERS at the ankle.

A vascular anomaly characterized by a radial or wedge-shaped arrangement of dilated VEINS draining into a larger vein in the brain, spinal cord, or the meninges. Veins in a venous angioma are surrounded by normal nervous tissue, unlike a CENTRAL NERVOUS SYSTEM CAVERNOUS HEMANGIOMA that lacks intervening nervous tissue. Drainage of venous angioma is fully integrated with the body's venous system, therefore, in most cases there is no clinical signs and rare bleeding.
