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.
Regional anesthesia numbs a large area, or region, of the body and is used for more extensive and invasive surgery. Regional anesthesia is often used for procedures involving the lower part of the body, such as caesarian sections, prostate surgery, and operations on the legs. For example, if regional anesthesia is used for prostate surgery, the patient is numb from his navel to his toes. Some patients feel pressure or tugging during surgery performed under regional anesthesia. The most common types of regional anesthesia are spinals and epidurals.
