The presence of sinusoidal portal hypertension stimulates renal sympathetic activity 100mg minomycin mastercard, enhancing First Principles of Gastroenterology and Hepatology A order 50mg minomycin fast delivery. Peritoneal fluid of less than 2 litres is difficult to detect clinically, but abdominal ultrasound is useful in defining small amounts of ascites of 500mL. As the volume of ascites increases, the abdomen becomes distended, often with fullness (bulging) in the flanks. Bulging flanks and the presence of flank dullness are the most sensitive physical signs for ascites, whereas eliciting a fluid wave or confirming shifting dullness are the most specific. Complications related to ascites and increased intra-abdominal pressure, such as umbilical hernia may be present. This is due to the presence of a normal diaphragmatic defect, which allows ascitic fluid to pass into the pleural cavity. Patients will also demonstrate signs and symptoms of a hyperdynamic circulation, such as systemic hypotension, resting tachycardia and warm periphery, as well as evidence of portal hypertension such as distended abdominal wall veins radiating from the umbilicus. Other complications of cirrhosis such as jaundice and muscle wasting, which can be quite profound, may also be present. Exactly 10 mL of ascitic fluid should be directly inoculated into blood culture bottles at the bedside. Indications for diagnostic paracentesis New Onset Ascites Hospital Admission of the Cirrhotic Patient Development of: o peritoneal signs/symptoms eg. Causes of Ascites Cirrhosis from any etiology (75%) Malignancies (15%) o Carcinoma of stomach o Carcinoma of colon o Pancreatic carcinoma o Hepatoma with or without cirrhosis o Metastatic intra-abdominal malignancies o Hodgkins and non-Hodgkins lymphoma o Ovarian carcinoma and Meigs Syndrome Heart failure (3%) Tuberculosis (2%) Pancreatitis (1%) Others (5%) o Acute Budd-Chiari syndrome o Nephrotic syndrome o Myxoedema o Ovarian hyperstimulation (result of in vitro fertilization) The appropriate frequency of a given cause of ascites is given in brackets. A high protein content may be associated with congestive heart failure, or Budd-Chiari syndrome (occlusion of the hepatic vein), and may also be seen in pancreatic ascites. In particular, abdominal ultrasound can detect even a few mLs of ascitic fluid and is highly sensitive (>95%) and specific (>90%). Abdominal ultrasound may also be used to establish the optimal site in which to perform the paracentesis, and will show the size of the liver and spleen. Treating the underlying etiology of cirrhosis has the potential to reverse the associated hepatic decompensation, thus the management of cirrhotic ascites begins with the treatment of the etiologic factors, if possible, such as abstinence from alcohol. Patients with decompensated cirrhosis from hepatitis B should be treated with antiviral therapy. Although bed rest will result in redistribution of body fluid, salt and fluid restriction is required to mobilise the ascites. The patient is usually prescribed a low salt diet containing 44-66 mmol sodium per day, which is even lower than that contained in a no- added salt diet. Professional dietary advice is necessary, and patients require specific instructions regarding where to purchase low salt food. Salt substitutes are contraindicated, as they often contain potassium chloride, and therefore predispose the patients who are taking potassium- sparing diuretics to the development of hyperkalemia. Patients should be carefully monitored with daily weights and with frequent 24-hour urinary sodium excretion measurements. The rate at which ascitic patients gain or lose weight can be used to assess compliance with the low salt diet, and the efficacy of diuretic treatment (Table 4). The urinary creatinine is measured simultaneously with as the urinary sodium to assess completeness of the urine collection. Random urine sodium assessments are unreliable, as urine sodium excretion varies over the + + course of the day. However, a urine Na /K ratio of >1 predicts with 95% accuaracy a urinary + Na excretion of >78 mmol/day. Predicting weight change in patients compliant with low salt (44 mmol Na/day) Diet Scenario I o Urinary sodium excretion is 100 mmol/day o Na intake = 44 mmol/day o Na output = 100 mmol/day o Na balance = (44-100)mmol/day = -56 mmol o Ascitic [Na] = 130 mmol/L o Therefore fluid loss = -56 mmol / 130 mmol/L = -0. Spironolactone, a distal diuretic with anti-aldosterone activity, is the preferred first line diuretic. Furthermore, any sodium reabsorption that is blocked by loop diuretics at the Loop of Henle will be reabsorbed when the sodium is delivered to the distal tubule. Combination diuretic therapy, with both a distal potassium sparing and a loop diuretic, acting on two different sites of the nephron, is now the standard of care. The combination approach has been proven to be more effective than sequential use of different classes of diuretics in the elimination of ascites. Spironolactone has a slow onset and offset of action because its half-life in cirrhotic patients can be as long as 35 hours. Therefore, frequent dose adjustments are unnecessary, and patients should still be monitored even after spironolactone is discontinued. One of the unacceptable side effects of spironolactone is painful gynecomastia in men. Amiloride, another potassium-sparing diuretic, is a less potent but certainly acceptable alternative to spirolactone.
