que se insertará el instrumento de paracentesis; Condición abdominal severa . Paracentesis peritoneal es una punción quirúrgica de la cavidad peritoneal para la aspiración de ascitis, término que denota la acumulación. La paracentesis sin embargo no está libre de complicaciones, por lo que es particularmente importante dar coloides como reemplazo, para prevenirla.

These factors cause an increased filtration pressure in the hepatic sinusoids and in the mesenteric capillaries leading to increased passage of fluid into the peritoneal cavity Witte et al Other drugs can promoje renal retention of sodium and these include nonsteroidal anti-inflammatory drugs, corticosteroids, oestrogens and metociopramide. Diuretic requirements after therapeutic paracentesis in non-azotemic patients with cirrhosis. One suggests that portal hypertension causes a loss of fluid into the peritoneun and leads to depletion of the intravascular volume underfilling theory with secondary and compensatory renal retention of sodium and water; another suggests that the fiver disease itself causes primary renal sodium and water retention leading to expansion of the vascular volume and hence the ascites overflow theory ; a third theory proposes a primary circulatory derangement resulting in a reduced effective arterial plasma volume with consequent renal retention of sodium and water Henriksen et al Measurement of the daily urine sodium output is useful in patients who do not respond to dietary salt restriction and diuretics as the finding of a good sodium excretion implies the intake of excess salt.
In advanced liver disease there is also a reduced ability to excret free water usually associated with a reduced glomerula filtration rate which contributes significantly to the hyponatraemia cornmonly seen in such patients. Transjugular intrahepatic portosystemic shunts: The concentration of organism in the ascites is low, making Gram staining of limited value and accounting for failure to culture organisms in a third to a half of cases Runyon et al Infection is a very serious complication of ascites spontaneous bacterial peritonitis and carries a generally poor prognosis.
The mechanisms underlying these theories are complex, paracenteeis understood, and beyond the scope of this paper as they do not yet have important implications for the management of hepatic ascites. Mechanical effects on the chest impair cardiopulmonary function and can cause dyspnoea which is relieved by removal of the ascites Table 4. Patients may present with a combination of a systemic illness with fever and leucocytosis, often associated with hepatic encephalopathy, and abdominal features of pain, peritonism and absent bowel sounds or with either independently.
Portal hypertension is an important factor in the development of ascites aboveand relief of portal hypertension should therefore improve ascites. Spontaneous Bacterial Peritonitis in cirrhosis: Durante la visita de seguimiento, usted puede discutir con su doctor cualquiera de los cambios o efectos secundarios que haya experimentado desde su procedimiento o tratamiento.
[Paracentesis as abdominal decompression therapy in neuroblastoma MS with massive hepatomegaly].
American Journal of Gastroenterology 76,b. The ascites amylase is high in pancreatic ascites and should be measured particularly when the protein content of ascites is high. Paracentesis reduces the free and wedged hepatic venous pressure without changing the hepatic venous pressure gradient and this persists for at least a week.
Mild to moderate ascites can be treated as an outpatient, but more severe ascites is treated best in hospital as these patients usually have more severe liver damage and they more often have adverse reactions to therapy. The thiazides are diuretics of intermediate potency which are little used in parwcentesis due to hepatic cirrhosis. Most of the peritoneal fluid originates from the hepatic sinusoids paraacentesis are high1y permeable and produce protein-rich interstitial fluid explaining the high ascites protein content in acute obstruction of the hepatic venous outflow e.
SBI is almost always caused by a single organism, and alternative diagnoses such as organ perforation should be considered when multiple organisms are found.
Ascites in Hepatic Cirrhosis
However surgical portal systemic shunts are not used for treating ascites as patients with intractable ascites generally have poor liver function and are poor candidates for such major surgical procedures. Prognosis is related largely to liver function, and patients with lesser degrees of ascites and better liver function respond better to treatment and survive longer.
American Journal of the Medical Sciences, Two different dosages of cefotaxime in the, treatment of spontaneous bacterial peritonitis in cirrhosis. Thoracentesis gives immediate relief from paracentesiss but usually only has a transient effect with repeated treatments eeded up to weekly.
Patients with more severe ascites who do not respond may require severe restriction of sodium to 40 mmol sodium daily which requires careful supervision by a dietician.
Initial sodium restriction can be modest when diuretics are used simultaneously with intake reduced to about 80 mmol daily by avoiding intrinsically salty food complicaciknes adding no salt in cooking or at table “no acIded salt diet. These patients need to be given sodium and water parenterally to replace their losses.
Rarely, measurement of the portal complicacioens pressure may reveal otherwise occult hepatic cirrhosis by revealing portal hypertension. Surgical portasystemic shunts proved effective in complicacionee secondary prevention of variceal bleeding but have fallen into disuse because thay were associated with an increased occurrance of hepatic encephalopathy and did not prolong fife.
The loop diuretics are the most powerful diuretics available acting on the ascending loop of Henle and to a lesser extent on the proximal tubules to inhibit sodium and chloride absorption.
Journal of Hepatology 25, Ascites in hepatic cirrhosis is associated with advanced liver disease and with poor hepatic function and portal hypertension, and consequently it is also associated with a poor prognosis. They are not wiclely used.
Paracentesis, however, needs to be done carefully and with aseptic precautions as it carries potentially serious complications including bacterial peritonitis and haemoperitoneum.
