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

Unfortunately, the sensitivity of ascites cytology for malignancy is low. Local diseases in the peritoneal cavity such as TB, malignant disease,and pancreatitis, damage capillaries and produce protein-rich ascites exudates. Mechanism and Effect on Hepatic Hemodynamics in Cirrhosis. Indeed, the rapid and complete efficacy in reducing ascites with rare complications made LVP plus albumin the first line of treatment for tense ascites.
Initial treatment with cefotaxime 1g 6-hourly intravenously is compliccaciones.
Hepatocellular carcinoma and paracenfesis intra-abdominal varices can also cause acute bleeding leading to hypovolaernic shock. 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 The North American study for the treatment of refractory ascites.
This is generally taken to mean a com;licaciones of sodium restriction and diuretic drugs, but paracentesis is used increasingly as an initial treatment for ascites owing to the speed with which it can be applied and a consequent reduction in hospital stay above. Blood and ascites culture should also be done, and the chance of isolating an organism from conplicaciones ascites is best if the fluid is drawn into blood complicackones bottles Runyon et al In fact, the first episode of ascites paracentesks a turning point of the disease which announces the risk of other complications of cirrhosis such as renal failure, hyponatremia, encephalopathy, variceal bleeding and bacterial infections.
In the case of hepatic cirrhosis, this includes imaging to detect cirrhosis, portal hypertension and complications of cirrhosis such as hepatocellular carcinoma, the causes of cirrhosis, and endoscopy for detection of oesophago-gastric varices which imply portal hypertension. Notwithstanding, all these advantages should be weighted with the consistent higher risk of encephalopathy. J Hepatol, 54pp.
Renal sodium retention is marked in ascites caused by hepatic cirrhosis aboveparticularly when the ascites is severe and hepatic dysfunction marked, pparacentesis accordingly restriction of sodium intake is important, particulary in initial treatment.
Norfloxacin prevents spontaneous bacterial peritonitis recurrence in cirrhosis: Cattau et al have shown that clinical examination detects peritoneal fluid in only a half of patients with less than a litre of ascites Table 3.
The most important investigation is immediate analysis of the ascites for polymorphonuclear leucocyte content and culture. Community-acquired SBP carries a more favourable prognosis than hospital-acquired SBP, perhaps because patients in hospital tend to be sicker. Recently, the most accepted criteria for defining refractory ascites are an ascites that cannot be mobilized or whose re-accumulation after large-volume paracentesis LVP cannot be prevented by medical therapy.
The serum ascites albumin gradient is superior to ocmplicaciones exudate-transudate concept in the differential diagnosis of ascites. Results of a prospective, randomized, multicenter study Hepatology 21, Aminoglycosides were used previously but are now avoided owing to their renal toxicity.
Indeed, although most patients will respond well to sodium restriction and diuretic drugs, paracentesis is used increasingly as a treatment of first choice probably because it is quicker and can reduce the length of hospital stay Gines et al Medicine 50, Diuresis starts complicacionee an hour within minutes of an intravenous dose and lasts for about six hours after an oral dose.
Tips versus drug therapy in preventing variceal rebleeding in advanced cirrhosis: Before diagnosing refractory ascites it is important to exclude unrecognised inappropriate sodium intake, failure to take diuretic drugs concomitant drug therapy causing sodium retention above and ascites due to causes other than cirrhosis Table 6 even in a patient with cirrhosis. Royal Infirmary of Edinburgh and the Department of Medicine. A total leucocyte count is not helpful as it is the short-lived polymorph cells which reflect infection.
Thoracentesis gives immediate relief from dyspnoca but usually only has a transient effect with repeated treatments eeded up to weekly. Previous reports had shown had shown that surgical shunts can elieve intractable ascites and reverse hepatorenal failure Ariyan et alFranco et al Diagnosis paracenteesis malignant ascites.
Mechanical effects on the chest impair cardiopulmonary function and can cause dyspnoea which is relieved by removal of the ascites Table 4. Complicacioens who are clinically well can be treated with broadspectrum quinolones such as ciprofloxacin. Ultrasonography is particularly useful in identifying small amounts of ascites as it can detect as little as mI of free peritoneal fluid Goldberg et aland in such cases it allows the aspiration of fluid for analysis.
Dig Liver Dis, 33pp. Once the transport capacity of the lymphatics is exceeded fluid accumulates in the peritoneal cavity and eventually ascites becomes paracfntesis.
compllicaciones Alternative antibiotics include other cephalosporins such as ceftriaxone, aztreonane and augmentin amoxicillin-clavulanic acid. A TIPSS shunt is probably the best treatment currently available as about half of patients have complete relief and aquarter partial relief Gordon et alStrauss et al This procedure causes a fall of portal pressure with reduction of the vascular collateral circulation.
Recently, covered stents has reduced the complications caused by failure of the stent patency. Mainly, we wished to explore which of the predicting variables could be used to prefer large-volume paracentesis or TIPS. Patients with paraventesis severe ascites who do not respond may require severe restriction of sodium to 40 mmol sodium daily which requires careful supervision by a dietician. SBI develops in patients with advanced cirrhosis who are susceptible to infection generally and specifically compllcaciones their ascitic fluid collections.
Ascites in cirrhosis is usually clear and straw or light green in colour, but it can also be cloudy, bloo -stained chylous or bile -stained.
CAMBIOS CARDIOVASCULARES EN LA CIRROSIS. EL IMPACTO DE LAS COMPLICACIONES Y LOS TRATAMIENTOS
Occasionally, infection reaches the ascitic fluid from recognised sources elsewhere in compkicaciones body and unusual sources include dental infections and the fallopian tubes. Bacteria probably reach the ascitic fluid as a result of bacteraemia, and as a high proportion of ascitic infections are with gut-related organisms, many must reach the complkcaciones by passing through the bowel wall.
Accordingly, preventative measures to support the circulation with a colloidal solution at the time of paracentesis are important as this prevents circulatory dysfunction. Am J Gastroenterol,pp.
[Paracentesis as abdominal decompression therapy in neuroblastoma MS with massive hepatomegaly].
The most effective treatment is a third- generation cephalosporin such as cefotaxime 1g intravenously 8 hourly. Automated low flow pump system for the treatment of refractory ascites: TB shows large variation in geographics distribution. Uncovered transjugular intrahepatic portosystemic shunt for refractory ascites: Seminars in Liver Disease 6, ,
