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.

A randomized double-blind trial of spironolactone versus placebo. Hepatology 4,b.
Blood and ascites culture should also be done, and the chance of isolating an organism from the ascites is best if the fluid is drawn into blood culture bottles Runyon et al Ascites can give rise laracentesis a number of secondary abdominal features including umbilical eversion, herniae, pale abdominal striae, scrotal oedema, and meralgia paresthetica from entrapment of the lateral cutaneous nerve of the thigh. Excessive diuresis can cause hypovolaemia and renal failure, and accordingly daily fluid losses shoulcl be limited to ml.
However surgical complicacilnes systemic shunts paraentesis not used for treating ascites as patients with intractable ascites generally have poor liver function and are poor candidates for such major surgical procedures. Norfloxacin is a poorly absorbed quinolone which reduces the aerobic Gram paracentesid gut flora without suppressing the anaerobic flora and it has proved successful in reducing recurrance of SBP.
Paracentesis, however, needs to be done carefully and with aseptic precautions as it carries potentially serious complications including bacterial peritonitis and haemoperitoneum. All, however, are associated with poor liver function and include activation of the renin-angiotensin-aldosterone system with high plasma and urine aldosterone, increased sympathetic activity possibly via a hepatorenal reflex arc, and the actions of such agents as arterial natriuric peptide, kallikrein-kinin prostaglandins, nitrous oxide, endothelin, and endotoxin.
The clinical features are those of cough, dyspnoea, chest pain or fever in a patient with a pleural effusion, of an associated spontaneous bacterial peritonitis, or of unexplained deterioration in a patients condition.
Patients requiring this treatment have advanced disease and encephalopathy and deterioration of complicacionrs function can occur fter TIPSS.
Sodium depletion Rarely, patients become truly sodium and water depleted following large fluid losses by paracentesis, diuresis or enteric losses. Retention of sodium by the kidneys is the main reason for this increase though renal water retention does occur in more advanced dasease table 1.
Mechanical effects on the chest impair cardiopulmonary function and can cause dyspnoea which is relieved by removal of the ascites Table 4. Many early deaths are attributable to serious complications such as hepatocellular carcinoma and spontaneous bacterial peritonitis, but patients with severe ascites who do not have such complications also often have a poor prognosis.
Furthermore, the ascites protein may rise during diuretic therapy Hoefs Peritonovenous shunts have been used successfully but are of limited value owing to frequent side-effects Stanley Transjugular intrahepatic portosystemic shunts: Spontaneous bacterial empyema in cirrhotic patients: 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 A variant of spontaneous bacterial peritonitis.
Reduced heart responses to stressful conditions such as changes in cardiac loading conditions in presence of further deterioration of liver function, such as refractory ascites, hepatorenal syndrome, spontaneous bacterial peritonitis and bleeding esophageal varices, have been recently identified.
Se aconseja programar que un familiar o un amigo lo lleve a su hogar una vez concluido el procedimiento. This is generally taken to mean a combination of sodium restriction and diuretic drugs, but paracentesis is used increasingly as praacentesis initial treatment for ascites owing to the speed with which it can be applied and a consequent reduction in hospital stay above.
Many patients acquire SBP while in hospital, and though these are likely the more ill and susceptible patients, intravascular cannulae and invasive investigations producing bacteraemia are additional important factors. Chronic parenchymal liver disease is the most cornmon cause of ascites, and Table 6 shows the main conditions from which it needs to be differentiated. 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.
Further investigation may be required to determine the cause of the ascites. Pleurodesis and surgical repair of diaphragmatic defects is often unsuccessful and fraught with serious complications.
Antibiotic prophylaxis is important to prevent recurrence and liver ed shoulcl be considered. Therapeutic interventions targeted to prevent and manage cardiovascular deterioration are in progress. Total paracentesis of all ascites reduces the wedged hepatic venous pressure and recently it has been reported also to decrease intravariceal pressure Kravetz et al ACE-inhibitors reduce glomerular filtration rate and sodium excretion paraventesis in doses which do not reduce the blood pressure. Pathophysiology of ascites and functional renal failure in cirrhosis.
