Malnutrition has a tremendous impact on respiratory functions. It affects respiratory muscle performance, lung structure, defense mechanisms, and control of ventilation and predisposes to respiratory failure and prolonged mechanical ventilation. Calling clinicians' attention to this common clinical problem is the first step toward developing a systematic approach to patient care in which correction of malnutrition is an integral part of the therapy. The increased morbidity and mortality in malnourished patients can be better understood when they are superimposed on other disease conditions, such as chronic lung disease, sepsis, trauma, and cardiovascular dysfunction. Most important is the fact that many of the consequences of malnutrition can be partially reversible with appropriate refeeding.

Intravenous alimentation is routinely used in many hospitalized pediatric patients, however, there are few reports of the nature and frequency of metabolic complications. In order to assess the frequency and nature of metabolic complications all children receiving parenteral nutrition from January 1, 1982 to December 31, 1982 were prospectively enrolled in the study. Data collection began with the institution of parenteral nutrition. Serum electrolytes, minerals, liver function tests, and renal function tests were followed weekly. A total of 201 patients received parenteral nutrition for 5378 days. Nutrition was delivered to 146 patients (4980 patient days) via a central line and 55 patients via a peripheral line (398 patient days). The sepsis rate was 3.7% in central lines used only for parenteral and 4.8% in multipurpose central lines. In general, complications were fewer in the patients supported peripherally. In patients supported centrally, hypoalbuminemia was the most commonly found abnormality followed by hypocalcemia, hypophosphatemia and hypomagnesemia, reflecting a malnourished state. One-third of the patients had abnormal liver function tests, and in half of those factors causing liver dysfunction other than parenteral nutrition were present. Abnormal renal function tests occurred in 10% of the patients. Thus, a high incidence of metabolic complications occurred in association with parenteral nutrition. Most were present during the initiation of parenteral nutrition, suggesting an abnormal metabolic state was present prior to the institution of parenteral nutrition. The frequency of low serum albumin and minerals is consistent with previous publications of the prevalence of malnutrition in hospitalized patients.

Major trauma often precipitates major malnutrition. In many patients, this malnutrition underlies the morbidity and mortality associated with major injury, often leading to multiple organ failure and refractory sepsis. The clinical challenge is to anticipate these potential nutritional problems and intervene early and appropriately, recognizing that it is far easier to prevent malnutrition than it is to reverse it.

The stimulated contraction-relaxation characteristics of the adductor pollicis muscle were used to assess nutritional state in patients and healthy controls. In both groups insufficient nutrition resulted in abnormal muscle function. The ratio of force of contraction at 10 Hz to that at 20 Hz yielded the best combination of sensitivity (87%) and specificity (82%). Sepsis resulted in abnormal muscle function, but the changes were easily distinguishable from those in subjects taking an inadequate diet. Long term administration of steroids, trauma, and surgery had no effect on muscle function. A prospective study of 11 malnourished patients with abnormal muscle function showed that all variables of muscle function returned to normal values with total parenteral nutrition. This reversal correlated significantly with the duration of parenteral nutrition and occurred before any change in anthropometric variables or plasma albumin concentration. Muscle function studies are sensitive and specific indicators of malnutrition; results depend on energy intake but are not influenced by administration of steroids, trauma, or surgery.

Malnutrition results in a wide variety of metabolic responses, depending on circumstances, from reactions to pure deprivation of nutrients to include the added stress of injury and sepsis. Important differences of response exist between adults and children. Weight loss with changes in carbohydrate, fat, and protein metabolism are well documented. Disturbances of fluid and electrolyte balance are newer areas of interest as are changes in requirements for micronutrients such as trace metals. Many of these metabolic changes are under hormonal control. The intestinal tract shares in the response to malnutrition, and the consequent changes in mucosal function determine the ability of the intestine to handle enteral feeds. Such a route for nutritional support is important in protecting intestinal function not only in absorption but also in hormone production. Enteral feeding is increasingly having an important role in the interactions between acute diarrhoeal disease and malnutrition.

Apple peel deformity of the small bowel is a variant of jejunal atresia with a high mortality. Forty five percent of these patients can be expected to die, most from anastomotic leaks with sepsis, or anastomotic failure with prolonged ileus and malnutrition. This report documents survival of three consecutive patients treated by an adaptation of the Santulli "chimney" anastomosis. This method accomplishes the goals of relief of intestinal obstruction, minimal resection, and preservation of tenuous intestinal blood vessels. All three patients had a benign postoperative course and made an uneventful recovery. Intestinal function is normal in each patient at 1 1/2 years. Based on this experience, it appears that a Santulli jejunojejunostomy combined with total parenteral nutrition offers the most promising operative strategy in the treatment of patients with apple peel bowel.

The effect of preoperative total parenteral nutrition (TPN) on morbidity and mortality was studied in medical records of discharged surgical patients. Patients were classified into two groups on the basis of their ability to meet established criteria for malnutrition and the use of preoperative or postoperative TPN. The control group consisted of 44 patients who received TPN only after surgery or for less than 5 days preoperatively. The experimental group consisted of 26 patients who received treatment for at least 5 days before surgery and/or after surgery. Nutrition parameters measured included serum albumin, total lymphocyte count, hemoglobin, weight, and percent weight loss. Major septic complications (MSC) considered were intra-abdominal sepsis, wound dehiscence, septicemia, and pneumonia. Other complications included respiratory failure, congestive heart failure, fistulas, urinary tract infection, shock, and death. The experimental group showed improvements after surgery in the nutritional parameters listed and had a lower incidence of morbidity and mortality. Deficits in serum albumin, total lymphocyte count, and weight losses greater than or equal to 10% have been significantly (p less than .01) linked to the incidence of MSC. MSC also has been more frequently noted among patients who did not have TPN prior to surgery and who died following surgery. Therefore, preoperative TPN does appear to make a difference in the outcome of surgery.

In order to assess the significance of malnutrition in determining surgical complications and the possibility of their reduction by preoperative nutritional support (PNS), a randomized controlled trial is being performed at our institution. The results relative to 100 patients who underwent major surgery for gastrointestinal disease, are presented here. In the treatment group 49 patients received 30 kcal/kg/day and 200 mg/kg/day of nitrogen for at least 7 days in the immediate preoperative period (nine patients were excluded from this group due to early surgery--seven cases; or refusal to accept PNS--two cases. Data analysis with their inclusion or exclusion showed similar results.) Fifty-one patients constituted the control group. The observed septic complication rate was, respectively, 30 and 35.3% (p:NS). When the analysis was restricted to the patients with abnormal instant nutritional assessment (INA), as defined by Seltzer et al (serum albumin less than 3.5 g/dl and/or total lymphocyte count less than 1500 cells/mm3), a statistically significant difference was observed in the incidence of sepsis between the two subgroups (21% vs 53.3%, p less than 0.05). Analogous results were obtained from the patients who underwent gastrectomy for gastric cancer: 16.7% of septic complications in the malnourished treated patients and 100% in the malnourished control ones (p less than 0.05). The occurrence of serious sepsis (sepsis score greater than or equal to 10, according to the scoring system developed by Elebute and Stoner) in the malnourished subgroups was 5.2% and 26.7%, respectively, (p = 0.09). The postoperative mortality rate was not significantly changed by the PNS (reduction from 3.9% to 2.5%, p:NS).(ABSTRACT TRUNCATED AT 250 WORDS)

Malnutrition is associated with increased incidence of surgical complications and mortality. The efficacy of preoperative parenteral nutrition in preventing septic states and mortality was evaluated in malnourished patients undergoing gastrointestinal surgery. The patients were allocated to three groups according to criteria of malnourishment. In all groups parenteral nutrition decreased the incidence of septic complications and serious sepsis as compared with control patients.

Sepsis is associated with severe metabolic disturbances and progressive failure of utilization of carbohydrates, lipids and proteins to meet the energy requirements of peripheral tissue. The causes of this condition are analysed. The interrelation between malnutrition and sepsis is discussed. Current concepts regarding the meeting of water and ion requirements, indications for administration of colloid solutions and infusion of glucose, lipid emulsions and amino acid solutions in each stage of sepsis are presented. Various views on the amount and quality of necessary nutrients are discussed providing evidence that a number of problems have to be solved yet.
