Alterations in serum ionized and total calcium, magnesium, and phosphate concentrations, during recovery from acute dehydrating gastroenteritis, were studied. Fifteen children with acute dehydrating gastroenteritis had serum concentrations of ionized and total calcium, magnesium, phosphate, sodium, potassium, chloride, urea, creatinine, and albumin, as well as acid-base status, evaluated during rehydration and up to 72-h postadmission. The total serum calcium corrected for albumin did not change significantly during rehydration and remained within the normal range. Although serum ionized calcium fell significantly at 24 and 72 h, its concentration was not sufficiently decreased to cause symptomatic hypocalcemia. Serum ionized calcium correlated significantly with pH (r = -0.57), bicarbonate (r = -0.63), and albumin (r = +0.65), but not with total serum calcium, magnesium, and phosphate. Serum magnesium remained within the normal range during the study period. Serum phosphate was increased on admission (2.64 +/- 0.77 mmol/L), decreased by 12 h (to 0.84 +/- 0.32 mmol/L), and then followed by a gradual increase. This study suggests that changes in serum ionized calcium in dehydrating gastroenteritis are not of clinical significance. However, changes in serum phosphate concentration need further evaluation.

Admissions to the Medical Paediatric Unit at Derby Regional Hospital in 1984 were reviewed. There were 536 admissions (289 males and 247 females). The average number of inpatients per day was 11.7, average duration of stay was 8.0 days, and there was one hospital death. Aboriginal children represented 90% of admissions and 59% of these were under two years of age. Several major problems were often encountered in individual children; these included respiratory, gastrointestinal and renal disease, failure to thrive and anaemia. Plasma electrolyte levels were measured in 82 children with gastroenteritis. Of these children 45 (55%) had a serum potassium level of less than 3.0 mmol/L and eight (10%) had a serum potassium level of less than 2 mmol/L. One hundred and four children were diagnosed as having pneumonia; 74 (71%) of them responded to penicillin. In 19 (21%) of 92 children who failed to thrive, no definite medical cause was found. The remainder had a combination of diarrhoeal disease, and chest and urinary tract infections. Anaemia, renal calculi and rheumatic fever are also common medical problems in the Kimberley region.

A controlled, randomised trial comparing the results of oral rehydration therapy with those of intravenous fluid treatment in 470 children with severe gastroenteritis was undertaken. The oral rehydration therapy was divided into two phases--a rehydration phase that used high sodium isotonic fluid at 40 ml/kg per hour and a maintenance phase using low sodium isotonic fluid (sodium 40, potassium 30, bicarbonate 25, chloride 45, and dextrose 130 mmol/l). The results indicate that oral rehydration treatment, used according to this protocol, is successful in treating severe diarrhoea and dehydration, and has considerable advantages over intravenous fluid therapy in reducing complications associated with the treatment of hypernatraemia, in promoting rapid correction of hypokalaemia and acidosis, in decreasing the duration of diarrhoea, and in promoting a greater weight gain at hospital discharge.

To investigate the effect of chronic protein-calorie malnutrition on intestinal repair after an enteric infection, we examined small intestinal structure, enzyme activity, and sodium transport in undernourished piglets during the acute and convalescent phases of a viral enteritis, transmissible gastroenteritis (TGE). Gnotobiotic pigs, nutritionally deprived from the age of 7 days, gained less weight than dietary controls from 14 days of age until the end of the study. Animals from malnourished and control diet groups were inoculated with TGE virus at 22-23 days and studied during the acute (40 h) and convalescent (4, 10, and 15 days) stages of this experimental enteritis along with noninfected dietary controls. After TGE infection, we observed a further decrease in weight gain and an increased mortality only in undernourished pigs. In jejunum and ileum of both dietary groups at 40 h after TGE infection, we observed comparable structural lesions, similar decreased activities of mucosal enzymes (sucrase, lactase, sodium-potassium-dependent ATPase), and increased thymidine kinase activities. Also we noted comparable diminution of glucose-stimulated jejunal sodium absorption in both dietary groups at 40 h. In control diet pigs, transport abnormalities recovered by 4 days after TGE infection and normal mucosal structure and enzyme activity returned over 4-15 days. In undernourished piglets, structural repair and enzyme abnormalities were prolonged when compared with the control diet group; glucose-stimulated sodium transport did not recover until 10 days after infection and never regained the enhanced activity seen in noninfected undernourished controls.(ABSTRACT TRUNCATED AT 250 WORDS)

A prospective randomized study of 100 well-nourished infants with acute gastroenteritis resulting in dehydration and acidosis was carried out at the Jackson Memorial Hospital, Miami from 1981 to 1983. Patients were randomly assigned to receive either standard intravenous therapy or oral rehydration. Infants in the latter group first received solution A containing 75 mEq/L sodium, 30 mEq/L potassium, 75 mEq/L chloride [corrected], 30 mEq/L bicarbonate, and 2 gm/dL glucose [corrected]. After ad libitum feeding for six hours, solution B containing 50 mEq/L sodium, 30 mEq/L potassium, 50 mEq/L chlorine, 30 mEq/L bicarbonate, and 3 gm/dL [corrected] glucose was given. With three exceptions (6%), oral rehydration was comparable to the intravenous regimen in clinical estimates of improvement, although the oral group had more stools in the first day. The oral group had faster correction of acidosis and a sustained rise in serum potassium concentration, whereas in the intravenous group the potassium concentration showed first a drop with a later increase, but levels were at all times below those in the oral group. Although potassium was given from the beginning of oral rehydration, and at a higher concentration than recommended by the World Health Organization, no hyperkalemia occurred. We concluded that oral therapy is safe, less expensive for patients, and more convenient for the medical and nursing staffs.

The main purpose of this study was to evaluate the effectiveness of an oral fluid therapy alone or combined with parenteral administration of a 5% dextrose solution to attenuate the clinical signs and the pathophysiological consequences of transmissible gastroenteritis in neonatal piglets. Eighteen two day old conventional piglets were infected with transmissible gastroenteritis virus while six others were used as controls (Group 1). At the onset of diarrhea, infected piglets were divided into three groups of six (Groups 2, 3 and 4). Piglets in group 2 were not treated and were fed a milk replacer ad libitum. Piglets in group 3 were removed from the milk replacer and placed on an oral glucose-glycine-electrolyte solution ad libitum. Those in group 4 were placed on oral fluid therapy and received a 5% dextrose solution intraperitoneally at the rate of 25 mL/kg of body weight once a day. Blood samples were collected in heparin within minutes after the infected piglets became comatose and from the controls at four or five days of age. The following variables were measured: packed red cell volume, blood pH, total plasma protein and bicarbonate, blood urea nitrogen, and plasma glucose, creatinine, chloride, inorganic phosphorus, sodium, potassium, magnesium and calcium. Vomiting and diarrhea appeared 12 to 24 hours postinoculation in the infected piglets. There was a sudden and rapid progression into a comatose and moribund state one or two days later whether the infected piglets were treated or not.(ABSTRACT TRUNCATED AT 250 WORDS)

Electrolyte homeostasis was maintained in 100 children with symptoms of acute gastroenteritis presenting without dehydration; their electrolyte disturbances and responses to oral electrolyte solution therapy were recorded. None of the children needed hospitalization, and 66% improved within 72 hours, the others requiring from 3-6 days. The electrolyte solution used was commercially available (Electral) and contained, including glucose to a 5% solution: sodium, 25 meq; potassium, 25 meq; calcium, 4 meq; magnesium, 4 meq; chloride, 30 meq; lactate, 4 meq; citrate, 15 meq; sulfate, 4 meq; and biphosphate, 5 meq per liter. In this study, when case electrolyte levels were compared with controls, a potassium deficiency of a mild to moderate degree was seen in half the children in this early phase; hence, the potassium level of the solution is most important. Hypokalemia was the major problem among these cases, as compared to hypo- or hypernatremia.

Oral rehydration is an ideal form of treatment of gastroenteritis in India both in large hsopitals and in rural health centers where adequate facilities and trained personnel are lacking. This paper concerns a study of oral rehydration in 30 patients (aged 17 days to 5 years) admitted to the Children's Ward (of Goa Medical College between April to August 1972) for gastroenteritis and 210 children who were treated in the Outpatients' Dept. (Ta 1). Tables 2 and 3 show the complaints on admission and clinical signs of the disorder. Fluid replacement was divided into 2 phases. Intravenous fluid thera was administered to all children admitted in shock. Rehydration was started in all cases without shock and was maintained with orally administered glucose electrolyte solution. 12 patients had severe dehydration, 9 moderate and 9 mild. Table 5 details the control of diarrhea while Table 6 details the amount oral fluids given to different age groups and to patients with varying degrees of dehydration. 2 patients (3- and 5- month old females) developed paralytic ileus that led to their deaths. Paralytic ileus is a grave complication with a high mortality rate. It can be prevented by early and adequate administration of potassium. It is possible that some of the 210 outpatients in this study had transient diarrhea, cured themselves of it or took electrolytes which prevented complications from developing. The practice of dispensing "salts" to outpatient appear promising and should be encouraged.

In a study of 91 babies with dehydration as a result of gastroenteritis the intraperitoneal route was found to be safe and effective in those with mild or moderate dehydration, but not in those who were severely dehydrated. The fluids found to be most effective in the intraperitoneal technique were normal saline with 28 mEq of potassium chloride per litre, or for hypertonically dehydrated babies half-strength Darrow's solution. This technique can be carried out by a nurse working single-handed if the baby is premedicated with promazine.

The main purpose of this work was to study changes in the balance of fluids, electrolytes and blood metabolites in neonatal piglets with severe transmissible gastroenteritis. Six two day old conventional piglets were infected with transmissible gastroenteritis virus while six others were used as normal controls. Blood samples were collected in heparin when the infected piglets were moribund. The following variables were measured: packed red cell volume, total plasma protein and bicarbonate, blood pH, blood urea nitrogen and plasma glucose, creatinine, chloride, inorganic phosphorus, sodium, potassium, magnesium and calcium. Vomiting and diarrhea appeared 12 to 24 hours postinoculation in the infected piglets and they were moribund one or two days later. Before becoming moribund, most of the piglets fell rapidly into a lethargic and comatose state. The most evident changes in their blood variables were an increase in packed cell volume, total protein, blood urea nitrogen, phosphorus and magnesium levels and a decrease in pH and bicarbonate concentration as well as a severe hypoglycemia. The results suggest that severe hypoglycemia coupled with metabolic acidosis and dehydration might be an important factor contributing to the high mortality rates caused by transmissible gastroenteritis in neonatal piglets. The hypoglycemia results from a combination of the inadequate glucose metabolism inherent to neonatal piglets and the acute maldigestion and malabsorption resulting from the diffuse and severe villous atrophy induced by the virus.
