In nine critically ill newborns, five of them with intractable diarrhea and four surgical patients, we administered a 5% crystalline aminoacids solution (AA) and glucose in sufficient amount to provide 120 cal times kg. in 24 hours. Six of them recovered after receiving parenteral alimentation for 3 to 15 days, gained weight during or after treatment and were discharged from the hospital in good conditions. Three died, one of them presented septicemia and two pneumonia and pulmonary infarcts. The solution used generated few metabolic alterations, the acid-base status remained within normal range and there were not important changes in the sodium and potassium serum concentrations. On the contrary, children with hyponatremia and hypokalemia at the beginning of the treatment, normalized these constants within the first hours, as diarrhea ceased. The most frequent complications were infiltrations and reaction of the surrounding tissue of the catheterized vein and local skin infection. Only one patient died of septicemia, possibly caused by this proceeding. In summary, parenteral alimentation though not free from risk, seems to be a useful proceeding when oral feeding is impossible or inadvisable. The utmost danger is septicemia. Metabolic changes are minimal and they do not mean a risk for child's life; nevertheless, there is a need for long term studies to bring up definite conclusions. The solutions in actual use are probably not the most physiological for the newborn. It is necessary to adequate them according to the new advances made on child nourishment during his first days of life.

On March 26, 1970, a 33-year-old male suffered intestinal infarction which required total enterectomy and duodeno-transverse colostomy. Nutrition was maintained in the hospital by daily parenteral feeding for 2 months postoperatively, after which parenteral feedings were decreased and stopped for long periods. Various oral dietary regimens failed to provide adequate nutrition, and the patient lost 40 kg and became severely malnourished during the next 13 months. In June 1971, supplemental home parenteral nutrition (PN) via an arteriovenous fistula was instituted on a 3 or 4 nights per week basis. The patient's weight and strength increased markedly after institution of the home supplemental PN program. The first fistula became occluded after 9.5 months of home PN use and subsequent successive fistulae have remained patent for 31.3, 8.8, and 5.5 months of use. The patient prepares his own PN fluids at home, using a commercial device for filling plastic intravenous fluid bags. Although several different types of fluid have been used, the current mixture of 25% glucose and 2.75% amino acids with added vitamins, potassium, calcium, magnesium, and insulin plus simultaneously administered lipid emulsion has proven most effective. Only when the patient's low fat, low oxalate diet is supplemented with this parenteral mixture 4 nights each week is he in positive nitrogen, phosphorus, and magnesium balance. However, his negative calcium balance is only partially corrected. There has been no sepsis, embolism, or fistula infection during 5 years of home PN.

Alterations occur in human muscle electrolyte and water composition in response to infection. There appear to be at least two basic mechanisms; the first is an exchange of sodium for potassium without alteration in water content of muscle. The second is an increase in cellular Na and water without a loss of K on a dry weight basis. In a series of studies in monkeys, Salmonella typhimurium sepsis was induced as an experimental model. Both patterns of muscle response to infection were detected. Electron probe microanalysis revealed that the loss of K concentration was due to an accumulation of intracellular saline which dilute the K content. The mechanism of this is unclear; however, a concomitant increase in undertermined osmoles in the serum suggests that there may be an increase in organic osmoles within the cell which leads to the dilution of intracellular K concentration.

Forty patients with a mean age of 56 yrs, all of whom required hemodialysis therapy, for mean of 32 days, were treated with a minimum of 2000 kilocalories of I.V. glucose, potassium orthophosphate with mulit-vitamins and 25 Gm of I.V. albumin. Patients were initially dialyzed daily and then every other day or 3 times/wk. Complications including pneumonia, GI bleeding, gram negative septicemia, shock, the need for tracheostomy and ventialtory assist were high. Overall survival rate was 33%. This survival rate we beleive to be high considering the complicated type of illness these patients had as well as our clinical experience prior to the use of total parenteral nutrition in the manner described in this report. Essential L-amino acids were not used based on our experience in 3 patients with hepatic and renal failure who developed worsening neurological findings with the use of this substance. We believe further that I.V. glucose and albumin may be preferred mode of hyperalimentation.

Ileostomy function was studied in 12 patients with an established ileostomy following proctocolectomy, in 6 of whom minimal amounts (less than 9 cm) and in 6 significant amounts (30-120 cm, mean 60 cm) of terminal ileum had been removed. Patients who had undergone significant ileal resection had daily faecal volumes considerably greater than those with minimal ileal resection (1202 +/- 284 ml versus 401 +/- 92 ml, P less than 0.001), and also greater daily outputs of sodium (146 +/- 53 mEq versus 43 +/- 12 mEq) and potassium (12.7 +/- 9.0 mEq versus 4.0 +/- 0.99 mEq). The percentage water content of the ileostomy fluid was greater in patients who had had the ileum resected (93.1 +/- 1.8% versus 89.8 +/- 2.5%). In addition, the sodium/potassium ratio in the urine in patients with a properly acting ileostomy after ileal resection was low. It is concluded that when recurrent inflammatory bowel disease, partial small bowel obstruction and intraperitoneal sepsis have been excluded there remains a number of patients whose high ileostomy output is due entirely to the amount of ileum resected. The management of patients with a high output ileostomy with codeine phosphate, Lomotil and oral administration of sodium chloride tablets is discussed.

The cytokine tumor necrosis factor-alpha (TNF alpha) is one of the major mediators of septic shock. Because vasodilation is a hallmark of sepsis and decreased vascular responsiveness has been implicated in the pathogenesis of septic shock, we studied the effect of TNF alpha on the mean blood pressure in conscious rats and vascular responsiveness to vasoconstrictors ex vivo using the standard organ bath method. Intravenous infusion of TNF alpha (0.006 or 0.06 mg/kg/hr for 10 hours) decreased mean blood pressure in a dose-dependent fashion. Contractile responses to norepinephrine were depressed dose-dependently in the aortic rings both with and without its endothelium. Aortic contractions by potassium depolarization were also depressed. These results suggest that TNF alpha induces non-specific vascular hyporesponsiveness, which is independent of the presence of the endothelium. The TNF alpha-induced vascular hyporesponsiveness might contribute to the hypotensive action of TNF alpha.

We report a 3-year analysis (1986 to 1989) of the management of 63 home parenteral nutrition patients, 40 with short-bowel syndrome and 23 with chronic intestinal obstruction with or without intestinal resection. Intravenous fluid requirements varied from 0.9 to 6 L/day, and the content of glucose varied between 46 and 531 g/day, protein varied from .0 to 85 g/day, fat from .0 to 100 g/day, sodium from 37 to 695 mEq/day, potassium from 30 to 220 mEq/day, chloride from 60 to 760 mEq/day, and acetate from 0 to 200 mEq/day. Body weight was normalized and well maintained in the majority of patients, but using the strict definition of deficiency as the presence of one abnormal value during 3 years, more than half had abnormal plasma chloride, glucose, alkaline phosphatase, serum glutamic oxaloacetic transaminase, total protein, albumin, selenium, and iron concentrations, and more than a third had low calcium, magnesium, vitamin D, and vitamin C levels. Normochromic anemia was seen in 73% and high blood creatinine associated with low urine volumes in 42%. Most (78%) returned to relatively normal lifestyles, but employability was occasionally impaired by loss of third-party insurance coverage resulting from a therapy that may cost $100,000 per year. Overall mortality was low (5% per year), but 73% needed readmission to hospital, mainly for suspected catheter sepsis. The results indicate that home parenteral nutrition has allowed many patients to survive gut failure and return to work but problems with chronic fluid, electrolyte and micronutrient deficiencies, catheter sepsis, and insurance coverage often restrict optimal rehabilitation.

The use of recombinant human erythropoietin (rhuEPO) has revolutionized the treatment of renal anemia, but the dose regimens have not been established. We studied the effects of subcutaneous rhuEPO given 4,000U (1 vial) every 5-10 days in 9 patients on continuous ambulatory peritoneal dialysis (CAPD). Ten stable CAPD patients (6 females and 4 males; mean age +/- SEM, 54.4 +/- 5.6 years; mean baseline hemoglobin concentration 7.3 +/- 1.2g/dL) were commenced on s.c. rhuEPO. None of the patients had a history of gastrointestinal bleeding, aluminum overload, sepsis nor receiving androgens. Seven patients were receiving 4,000 U rhuEPO weekly, one patient each was receiving 4,000 U every 5 and 10 days (range, 66.7-89.3 U/kg/week). The dose was adjusted every 4 weeks according to response by altering the dose interval. The mean hemoglobin concentration increased from 7.3 +/- 1.2 g/dL to 10.3 +/- 1.1 g/dL over 8 weeks. There was no significant changes in the serum ferritin, urea, creatinine and potassium levels. One patient required an increase in antihypertensive therapy. We feel that s.c. rhuEPO 4,000 U given on an intermittent basis is effective in the treatment of anemia in CAPD patients. The administration of a single vial each time is convenient and cost sparing. The gradual rise in hematocrit avoids complications.

We have previously shown the safety and efficacy of University of Wisconsin solution for hypothermic preservation of the human donor heart in a pilot group of 16 transplant recipients. The present study is a randomized clinical trial comparing University of Wisconsin solution to conventional preservation using crystalloid cardioplegia and saline storage within a 4-hour limit of ischemia. Heart transplant recipients (n = 42) were randomized into two groups: those receiving hearts preserved by University of Wisconsin solution, the UWS group (n = 22), and those receiving hearts preserved in the conventional manner, the CCS group (n = 20). Recipient age, gender, heart disease, and preoperative inotropic support and donor age, gender, and mean ischemic time in hours (UWS 2 hours 36 minutes, range 1 hour 36 minutes to 2 hours 53 minutes; CCS 2 hours 20 minutes, range 1 hour 20 minutes to 2 hours 44 minutes; p = not significant) were similar. Significant differences observed between the two groups included (1) mean time (minutes) from reperfusion to achieve a stable rhythm, (2) need for intraoperative defibrillations, (3) need for transient cardiac pacing, and (4) integrated postoperative creatinine kinase and aspartate aminotransferase release over 48 hours. There was no difference in postoperative electrocardiogram, endomyocardial biopsy, or hemodynamics. One UWS patient died of sepsis and another of a ruptured cerebral aneurysm. UWS is safe for donor organ arrest and preservation despite high viscosity and potassium concentration. When compared with CCS hearts, hearts preserved in UWS regained electrical activity more rapidly and had better myocardial protection as demonstrated by enzymatic analysis. Further investigation is required to determine the effects of UWS preservation on long-term survival, to determine the prevalence of rejection and graft atherosclerosis, and to test the ability of UWS to extend donor ischemic time in human cardiac transplantation.

Escherichia coli hemolysin, a transmembrane pore-forming exotoxin, is considered an important virulence factor. In the present study, the possible significance of hemolysin production was investigated in a model of septic lung failure through infusion of viable bacteria in isolated rabbit lungs; 10(4) to 10(7) E. coli/ml perfusate caused a dose- and time-dependent appearance of hemolysin, accompanied by release of potassium, thromboxane A2, and PGI2 into the perfusate. Concomitantly, marked pulmonary hypertension developed. Inhibitor studies suggested that the pressor response was predominantly mediated by pulmonary thromboxane generation. Administration of hemolysin-forming E. coli additionally caused a protracted, dose-dependent increase in the lung capillary filtration coefficient, followed by severe edema formation. The permeability increase was independent of lung prostanoid generation. An E. coli strain that releases an inactive form of hemolysin completely failed to provoke the described biophysical and biochemical responses. Preapplication of 2 x 10(8) human granulocytes was without effect in the present experimental model. We conclude that the hemolysin produced by low numbers of E. coli organisms can provoke thromboxane-mediated pulmonary hypertension and severe vascular leakage. E. coli hemolysin and, possibly, other related cytolysins may thus contribute directly to the pathogenesis of acute respiratory failure under conditions of sepsis or pneumonia.
