[sen´tral] pertaining to a center; located at the midpoint.central cord syndrome injury to the central portion of the cervical spinal cord resulting in disproportionately more weakness or paralysis in the upper extremities than in the lower; pathological change is caused by hemorrhage or edema.

Central cord syndrome. From Ignatavicius and Workman, 2002.central fever sustained fever resulting from damage to the thermoregulatory centers of the hypothalamus.central nervous system the portion of the nervous system consisting of the brain and spinal cord. See also Plate 14.central venous catheterization insertion of an indwelling catheter into a central vein for administering fluid and medications and for measuring central venous pressure. The most common sites of insertion are the jugular and subclavian veins; however, such large peripheral veins as the saphenous and femoral veins can be used in an emergency even though they offer some disadvantages. The procedure is performed under sterile conditions and placement of the catheter is verified by x-rays before fluids are administered or central venous pressure measurements are made.
Selection of a large central vein in preference to a smaller peripheral vein for the administration of therapeutic agents is based on the nature and amount of fluid to be injected. Central veins are able to accommodate large amounts of fluid when shock or hemorrhage demands rapid replacement. The larger veins are less susceptible to irritation from caustic drugs and from hypertonic nutrient solutions administered during parenteral nutrition.Patient Care. Patients who have central venous lines are subject to a variety of complications. Air embolism is most likely to occur at the time a newly inserted catheter is connected to the intravenous tubing. Introduction of air into the system can be avoided by having the patient hold his breath and contract the abdominal muscles while the catheter and tubing are being connected. This maneuver increases intrathoracic pressure; if the patient is not able to cooperate, the connection should be made at the end of exhalation.
Sepsis is a potential complication of any intravenous therapy. It is especially dangerous for patients with central venous lines because they are seriously ill and less able to ward off infections. Careful cleansing of the insertion site, sterile technique during insertion, periodic changing of tubing and catheter, and firmly anchoring the catheter to prevent movement and irritation are all essential for the prevention of sepsis.
Formation of a clot at the tip of the catheter is indicated if the rate of flow of intravenous fluids decreases measurably or if there is no fluctuation of fluid in the fluid column. Preventive measures include maintaining a constant flow of intravenous fluids by IV pump or controller, periodic flushing of the catheter, heparin as prescribed, and looping and securing the catheter carefully to avoid kinks that impede the flow of fluids. Cardiac arrhythmias can occur if the tip of the catheter comes into contact with the atrial or ventricular wall. Changing the patient's position may eliminate the problem, but if ectopic rhythm persists, additional interventions are warranted.central venous pressure (CVP) the pressure of blood in the right atrium. Measurement of central venous pressure is made possible by the insertion of a catheter through the median cubital vein to the superior vena cava. The distal end of the catheter is attached to a manometer (or transducer and monitor) on which can be read the amount of pressure being exerted by the blood inside the right atrium or the vena cava. The manometer is positioned at the bedside so that the zero point is at the level of the right atrium. Each time the patient's position is changed the zero point on the manometer must be reset. For a multilumen catheter the distal port is used to measure central venous pressure; for a pulmonary artery catheter the proximal port is used.
An arterial line can also be used to monitor the central venous pressure. The waveform for a tracing of the pressure reflects contraction of the right atrium and the concurrent effect of the ventricles and surrounding major vessels. It consists of a, c, and v ascending (or positive) waves and x and y descending (or negative) waves. Since systolic atrial pressure (a) and diastolic (v) pressure are almost the same, the reading is taken as an average or mean of the two.
The normal range for CVP is 0 to 5 mm H₂O. A reading of 15 to 20 mm usually indicates inability of the right atrium to accommodate the current blood volume. However, the trend of response to rapid administration of fluid is more significant than the specific level of pressure. Normally the right heart can circulate additional fluids without an increase in central venous pressure. If the pressure is elevated in response to rapid administration of a small amount of fluid, there is indication that the patient is hypervolemic in relation to the pumping action of the right heart. Thus, CVP is used as a guide to the safe administration of replacement fluids intravenously, particularly in patients who are subject to edema" >pulmonary edema. Central venous pressure indirectly indicates the efficiency of the heart's pumping action; however, pulmonary artery pressure is more accurate for this purpose.
A high venous pressure may indicate heart failure" >congestive heart failure, hypervolemia, tamponade" >cardiac tamponade in which the heart is unable to fill, or vasoconstriction, which affects the heart's ability to empty its chambers. Conversely, a low venous pressure indicates hypovolemia and possibly a need to increase fluid intake.

Q. Is fibromyalgia related to Central Nervous System? Is fibromyalgia related to Central Nervous System? Among men and women who is more prone to the symptoms of fibromyalgia?A. here is a quote from the National Fibromyalgia Association site:
"Little research has been conducted that measures the prevalence of fibromyalgia, and estimates vary widely as to the proportion of male versus female patients. A 1999 epidemiology study conducted in London found a female to male ratio of roughly three to one. However, a 2001 review of the research literature in Current Rheumatology Reports stated the ratio was nine to one."
