jugular venous pressure. Back pressure exerted into the jugular veins from the right side of the heart.easure the vertical height of the fullness seen as the jugular vein fills. In the healthy (and in the dehydrated) little or no blood is seen in the jugular veins, and they appear to be flat. In right-sided heart failure, the column of blood distends the jugular veins to a height of 5 to 6 cm or more.
The purpose of this study is to compare local with spinal anesthesia in two groups of patients submitted to knee arthroscopy. Sixty-five patients were divided in two groups; based on the anesthesia method used, and submitted to the same surgical routine and postoperative analgesia protocol.
Arthroscopy (also called arthroscopic surgery) is a minimally invasive surgical procedure on a joint in which an examination and sometimes treatment of damage is performed using an arthroscope, an endoscope that is inserted into the joint through a small incision.rthroscopy can also be performed just for diagnosing and checking of the knee; however, the latter use has been mainly replaced by magnetic resonance imaging. During an average knee arthroscopy, a small fiberoptic camera (the arthroscope) is inserted into the joint through a small incision, about 4 mm (1/8 inch) long.
