Patients with refractory ascites and HRS should be considered to present an urgent indication for peritoneovenous shunting. The shunt offers a method of continuous reinfusion of ascitic fluid which corrects avid sodium retention, oliguria and azotemia. Severe encephalopathy, jaundice or peritoneal sepsis--common complications of cirrhosis--contraindicate installation of the shunt before improvement occurs. Associated cardiac disease does not contraindicate the use of the shunt provided that ascitic fluid is removed at the time of operation and large amounts of diuretics are used. This operation has also proved useful in ascites attributed to causes other than cirrhosis. The main complications include disseminated intravascular coagulopathy, hepatic coma and sepsis in a few patients. Results of a randomized prospective study indicate that the shunt should probably be considered in patients with diet-resistant massive ascites even before they prove to be refractory to diuretic therapy.

Over a period of 2 years, 82 patients out of 2,390 (3.43%) admitted to an intensive care unit developed acute renal failure (ARF). The diagnosis of ARF was based on the usual criteria of oliguria, a rising blood urea nitrogen and creatinine, urine sodium concentration greater than 20 mmol/l and a U/P osmolality ratio less than 1.1. In 9.2% of patients the latter two criteria were misleading. Sepsis was the commonest cause of vasomotor nephropathy but in 20.7% potentially nephrotoxic agents had been administered before development of ARF. Overall mortality was 73.2%, with patients older than 50 years of age having the highest mortality. ARF is associated with prolonged bed occupancy--an average of 59.8 days for the dialysed patients with ARF versus an average length of stay of 8.4 days for the hospital overall.

Twenty infants and young children with hereditary fructose intolerance (HFI) were admitted to hospital. None was diagnosed at admission. Referals were for vomiting of unknown aetiology (16X), pyloric stenosis or hiatus hernia (5X), toxic condition (3X), and hepatomegaly of unknown origin (5X). Feeding difficulties (20X), vomiting (18X), and failure to thrive (16X) were leading symptoms. The most frequent clinical findings were hepatomegaly (18X), pallor (14X), haemorrhages (13X). Ascites, oliguria, tachypnoea, fever, splenomegaly and rickets were less frequent. Laboratory findings were indicative of disturbed hepatic and renal tubular function and also of disturbed intermediary metabolism (hypokaliaemia, hypophosphataemia). However, hypoglycaemia was found in only 4 out of 15 patients tested. Differential diagnosis after hospital admission centered on metabolic disorders such as glycogenoses, galactosaemia, tyrosinosis, or Wilson's disease. Hepatitis, toxic hepatosis, liver tumour, intrauterine infection and sepsis were also considered. Eleven children had first ingested fructose within the first 6 weeks of life. The diagnosis was usually established only many weeks or months after first fructose intake and appearance of symptoms. This documents how difficult the diagnosis of this disease can be both in practice and in hospital. The course was severe in 11 children and lethal in 4. In only 5 patients was the course mild. The 16 survivors are doing well under fructose-exclusion diet. Irreversible visual impairment after intraocular haemorrhage occurred once. In each case HFI could have been suspected immediately, had a detailed nutritional history been taken. Practising paediatricians should know the composition of commonly used infant formulae. They should never prescribe sugared condensed milk for intractable vomiting prior to excluding HFI. Solution for intravenous infusion containing fructose and sorbitol are life-threatening for undiagnosed HFI patients.

One hundred fifty of 490 patients undergoing open heart surgery had renal failure attributable to cardiopulmonary bypass. In 69, serum creatinine concentrations did not exceed 2 mg/dl and returned to normal by the fourth postoperative day. In 60 patients, serum creatinine attained levels between 2 and 5 mg/dl, oliguria did not develop, and recovery of renal function occurred within 4 to 37 days. Serum creatinine increased to levels exceeding 5 mg/dl in 21 patients, 11 of whom were oliguric. Despite dialysis, 14 of these patients died from cardiac causes or sepsis. Prolonged cardiopulmonary bypass time, hypotension, oliguria, low output syndrome, and hemoglobinemia during open heart surgery correlated with the development of renal failure postoperatively. Although severe renal failure was an uncommon complication after open heart surgery, its occurrence carried a grave prognosis.

The acute onset of oliguria and azotemia in the postoperative setting may be caused by pre-renal causes or intrinsic renal damage. The first step in arriving at a diagnosis is to review the history as noted above for clues regarding fluid balance, treatment with nephrotoxins, etc. The typical patient with prerenal azotemia will present with evidence of the recent onset of worsening of pre-existing cardiac disease, renal or gastrointestinal fluid loss, or the accumulation of acites, edema, or retroperitoneal fluid. In the absence of very recent diuretic therapy, he will be excreting a scant amount of concentrated (greater than 400 mOsm per L) sodium free (less than 10 to 20 mEq per L) urine. The serumBUN/Cr ratio is often greater than 15 to 20:1, and their urinary sediment will be bland. In an occasional patient in whom these studies give equivocal results, additional help may be obtained with measurements of central venous pressure (CVP) or pulmonary wedge pressure (PWP) and by noting their response to intravenous fluid loading. A rising CVP or PWP in the face of salt loading is, of course, evidence against prerenal azotemia. Patients with obstructive uropathies may be oligoanuric or polyuric-occasionally a characteristic alternating polyuria and oliguria is found (due to displacement of a stone or relief of edema). When oliguric their urine typically contains substantial amounts of sodium (greater than 20 mEq per L), is isotonic, and their OsmU:OsmP is les s than or equal to 1.2. Their urinary sediment will reflect the cause of their obstruction as noted above. A renal scan, ultrasound study, or infusion IVP are mandatory to rule out the possibility of obstructive uropathy. If these nonivasive studies are equivocal, one must consider doing a unilateral retrograde. The development of ATN usually occurs in the setting of hypotension, sepsis, dehydration, and with exposure to nephrotoxins. Most patients with be excreting scant amounts of isotonic urine containing more than 20 to 30 mEq per L of sodium. Their CrU:CrP is less than or equal to 20:1 and their urinary sediment reveals many epithelial cells and casts. Those patients with nonoliguric ATN have urine outputs which may exceed 2 liters per day. Despite this output they demonstrate a stepwise increase in serum urea and creatinine. Urine sodium and osmolality are not very helpful in this setting. Many such patients do have low (less than 20 mEg per L) urine sodium concentration and excrete isotonic urine.

Acute renal insufficiency after cardiopulmonary bypass can lead to a significant morbidity from fluid overload and electrolyte disturbance, impede pulmonary gas exchange, and postpone weaning from mechanical ventilation. The limitations placed on free water intake result in severe restriction of nutrition while diuretic therapy causes electrolyte imbalance. Artificial renal support either in the form of peritoneal dialysis or hemodialysis may be complicated by sepsis and hemodynamic instability. We reviewed our experience with the use of continuous arteriovenous hemofiltration, an extracorporeal technique for removal of solutes, toxins, and water in critically ill patients with cardiac failure complicated by acute renal insufficiency and hemodynamic instability after cardiopulmonary bypass. Ten infants and children with renal insufficiency caused by low cardiac output had continuous arteriovenous hemofiltration instituted for indications including sepsis, volume overload, oliguria for more than 24 hours nonresponsive to diuretic therapy, and the need for hyperalimentation. All were supported by mechanical ventilation and receiving high-dose inotropic support. Arterial and venous vascular access was successfully obtained by cannulation of the femoral artery and vein in nine patients. Anticoagulation of the circuit was achieved with heparin infusion (6 to 20 micrograms/kg/hr) and monitored by measurement of activated clotting time. The continuous arteriovenous hemofiltration circuit was replaced if there was clot formation, or at 3 days after placement. Dialysis solution (Dianeal) 1.5% or 0.5% was infused as prefilter dilution. With the use of continuous arteriovenous hemofiltration, 20 to 100 m/hr of ultrafiltrate was removed, which allowed correction of hypervolemia, and caloric intake increased from 13.5 kcal/kg/day to 79.5 kcal/kg/day. Continuous arteriovenous hemofiltration was maintained between 5 hours and 8 days and was well tolerated in all patients. Serum urea and creatinine levels declined during continuous arteriovenous hemofiltration. We conclude that continuous arteriovenous hemofiltration is a safe and effective method for fluid and electrolyte homeostasis and that it thus allows hyperalimentation in infants and children after cardiac operations.

Hemofiltration was performed in 15 patients with refractory congestive heart failure. All of these patients had oliguria, although intensive treatment with diuretics, digitalis, vasodilators, and catecholamines was prescribed. Hemofiltration was performed under hemodynamic monitoring in 14 patients. The water removal by hemofiltration decreased pulmonary arterial pressure, pulmonary capillary wedge pressure and right atrial pressure. Despite these hemodynamic improvements, nine patients (60%) died within one month after the start of hemofiltration; the causes were fatal arrhythmia in three, renal failure in two, sepsis in one and irreversible cardiogenic shock in three. Oliguria for over 15 h or a serum creatinine concentration of more than 4.0 mg/dl at the start of hemofiltration related to poor prognosis. In view of these results, hemofiltration for refractory heart failure should be started earlier and performed carefully in order to avoid arrhythmia, cardiogenic shock, and other complications.

Many infants with hypoplastic left heart syndrome are now treated with heart transplantation. Preoperative or postoperative systemic/renal hypoperfusion occurs frequently, however, resulting in perioperative kidney failure. Of 45 neonates undergoing heart transplantation at our institution, we report on 10 (22%) who required postoperative peritoneal dialysis. Patients' age at transplantation ranged between 1 and 31 (mean, 16.7) days, average weight was 2912 (range, 2140 to 3664) gms. Peritoneal dialysis was started at a mean of 51 hours after transplantation for treatment of anuria (5 patients, 50%), oliguria (3 patients, 30%), fluid overload or hyperkalemia (1 patient each, 10%) and continued for a mean of 101 +/- 90.5 (range, 33 to 270) hours. The value for blood urea nitrogen fell from 46.7 +/- 15.6 mg/dl to 14.3 +/- 10.5 mg/dl, and serum creatinine levels decreased from 2.4 +/- 1.0 mg/dl to 0.6 +/- 0.3 mg/dl throughout peritoneal dialysis. All patients continued to receive cyclosporine during dialysis. Hyperglycemia developed in four patients. Five of 10 patients had ongoing sepsis during dialysis, but only one died while on dialysis (10%). Two patients died late, after peritoneal dialysis was discontinued. Follow-up ranges from 2 months to 5 years. At most recent follow-up, mean creatinine level was 0.5 +/- 0.1 mg/dl. We conclude that aggressive peritoneal dialysis may result in high salvage rates with low morbidity, without the need to discontinue cyclosporine in the setting of neonatal heart transplantation and acute kidney failure.

The records of 110 patients with acute renal failure (ARF) admitted to the Department of Medicine of the Philippine General Hospital during a 5-year period (1983-1988) were reviewed. The objectives were to evaluate the clinical profile of ARF patients and to determine what factors influenced mortality. Infection significantly influenced the causation and prognosis of ARF. Fifteen patients died, for an overall mortality rate of 14%. Forty-six clinical variables were analyzed in order to identify factors correlated with mortality. Four variables significantly increased the risk of death from ARF: older age, hyperkalemia, oliguria, and presence of sepsis on admission. These characteristics define a subset of patients for whom more aggressive treatment of ARF is warranted.

Fifty-two clinical charts of children who had been discharged from this hospital, after being treated for acute renal failure, were analyzed to determine the incidence, presentation and results of the treatment used. We found that 0.7% of the total number of children admitted developed this complication and that 4/5 of them were under two years old. The initial illnesses were gastroenteritis, bronchial pneumonia, cyanogenic cardiopathies and sepsis. Some of the patients had hypoxic episodes or went into hypovolemic shock or a combination of both. In half of the patients diagnosis was reached from anamnesis, from of oliguria, acidosis and nitrogen retention. In the rest from whom a urine sample was obtained, the diagnosis was confirmed when the FeNa was higher than 2 and because the U/P osmolarity and urea were under 1.3 and 5 respectively. The oliguric type of acute renal failure was seen in 65% of the cases; the non-oliguric type in 35%. In the first group the mortality rate reached 6.5% even though a third of them were placed under dialysis. Yet, in another 7 cases, dialysis could not be used because the child was in shock. Of the 18 cases of non-oliguric acute renal failure, 12 recovered; only 3 required dialysis. We conclude that the high mortality rate in cases of acute renal failure depends on the severity of the underlying illness, the age of the patient and the delay in the diagnosis of the disease. The use of dopamine and furosemide, as well as the application of hemoperfusion instead place of peritoneal dialysis in neonates with sepsis, could improve results.
