Particulate and bacterial contamination of IV fluids and drugs have been implicated in venous thrombosis, infusion phlebitis, suppurative thrombophlebitis, pyrogenic reactions, and systemic sepsis. In a study of the inflammatory potential of the filterable residue of sodium cephalothin, we have found a tissue-specific reaction with venous endothelium but not with cutaneous or subcutaneous tissues. In a controlled animal model, removal of particulates from an infusion by use of a 0.45 micron in-line membrane filter reduces the incidence and severity of infusion phlebitis.

Insulin glucose therapy can correct hyponatraemia and renal sodium retention in burns, sepsis and circulatory failure. A case of fulminant hepatic failure (F.H.F.) is described in which the same effect was observed. Insulin was thought to have corrected abnormal cell membrane permeability. The actions of insulin are discussed in relation to its possible role in the management of F.H.F.

White blood cell counts and nitroblue tetrazolium dye tests were performed in three groups of dogs before and after the injection of Escherichia coli using colistimethate sodium and cephalothin sodium in the second and third groups, respectively, prior to the induction of sepsis. The response was a diminished white blood count and increased nitroblue tetrazolium dye test percentage in all groups. When antibiotic administration was performed prior to the induction of sepsis, the increase in the nitroblue tetrazolium reduction dye test was much more evident despite the overwhelming dose of bacteria given, suggesting that antibiotics given preoperatively will prevent the toxic effects of bacteria on the neutrophil and will enhance the phagocytic activity of the neutrophil.

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.

Hospital nursery A has used chloramphenicol and nursery B has used the combination of penicillin G sodium and kanamycin sulfate routinely in the treatment of neonatal sepsis and other bacterial infections. A hypothesis was formulated that these different antibiotic pressures would select out a substantial number of populations of resistant bacteria in each of the two nurseries. This was tested by periodic sampling of the skin, mouth, and rectal flora of babies and the permanent personnel in these nurseries. These bacteria were studied for susceptibility to a number of antibiotics. The population of resistant strains selected out was correlated with the antibiotics used in each nursery. There is a need for continuing surveillance of hospital nursery strains of bacteria for in vitro susceptibilities to commonly prescribed antimicrobials.

To determine the source of pyococci causing attacks of sepsis in infantile eczema 20 patients with continuing eczema were followed up for one year, regular swabs being taken from the skin, nose, throat, and family contacts. The staphylococci were phage typed and the streptococci serologically typed. Staphylococci of the same phage type in most cases remained in reservoir sites on the skin and coincidently in the nose. Staphylococci causing attacks of clinical sepsis arose from these persistently colonized sites. Staphylococci of the same phage type were also common in family contacts. Streptococci of the same group in most cases did not remain on the skin. Streptococci causing attacks of clinical sepsis arose as new infections from external sources, sometimes from throat infections in the patient or family contacts. Strains of streptococci which are known to be associated with glomerulonephritis were isolated. It has been confirmed that staphylococci resistant to neomycin and sodium fusidate quickly emerge after the topical use of these antibiotics. Streptococci are highly resistant to neomycin and gentamicin, and moderately resistant to sodium fusidate, so the use of these antibiotics in topical steroid preparations will have little effect in preventing further attacks of clinical sepsis in these patients.

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.

In a retrospective study covering the period January 1972 to June 1974, recovery rates of bacteria and of fungi were generally equivalent with tryptic soy broth, Thiol, thioglycolate, and Columbia broth media (all under vacuum with carbon dioxide and sodium polyanetholesulfonate). An additional biphasic medium consisting of brain heart infusion broth and a brain heart infusion agar slant, which was inoculated only where fungal sepsis was suspected clinically, yielded significantly higher recovery rates of fungi. There were 29 instances of cultures with fungi in both the biphasic and broth media, 80 instances of cultures with fungi only in the biphasic medium, and no instances of fungi only in the broth media. The isolates were as follows: Candida albicans, 74; C. parapsilosis, 20; C. tropicalis, 16; Torulopsis glabrata, 18; Torulopsis sp., 1; Cryptococcus neoformans, 12; C. laurentii, 2; and Histoplasma capsulatum, 16. Despite routine subcultures of the broth media to chocolate blood agar within 24 h of inoculation and after 5 days of incubation, detection of fungemia was significantly improved by the use of a biphasic medium.

Furosemide frequently is advocated as a prophylaxis against renal failure in septic and injured patients; this effect is thought to be secondary to an increase in renal blood flow. This postulate was tested within 72 hours of admission in 22 previously healthy patients with acute pancreatitis (two), massive trauma (ten), or severe sepsis (ten). Renal clearances of inulin (GFR), para-amino hippurate (ERPF), sodium (CNA), osmoles (COsm), and free water (CH2O) were measured in milliliters per minute before and after the intravenous infusion of furosemide (0.5 mg. per kilogram of body weight). Renal vein PAH levels (EPAH) in eight patients were used to calculate true renal plasma flow (TRPF), true renal blood flow (TRBF), and renal vascular resistance (RVR). Furosemide caused a significant increase in urine volume, CNa, and COsm; there were no significant changes in GFR, ERPF, RVR, TRBF, and EPAH. These findings also were observed when the patients were subgrouped according to elevated, normal, or low renal plasma flow and elevated renal vascular resistance. No significant changes were seen in EPAH, thus making a redistribution of renal blood flow unlikely. These studies indicate that furosemide has only a diuretic effect and no hemodynamic effect in the kidney; it has the potential of seriously reducing the circulatory volume and causing renal failure in critical patients.

The protease inhibitor aprotinin was given a) in experimental septic shock, and b) in patients with hepatic cirrhosis and ascites, since in both conditions, activation of the plasma kallikrein-kinin system is associated with pathological systemic vasodilatation, which may trigger reflex neuroendocrine activation and renal solute retention. Given early in experimental sepsis, aprotinin maintained the arterial pressure, systemic vascular resistance (SVR), creatinine clearance and sodium excretion, all of which fell in controls. Aprotinin also blocked increases in pulmonary artery pressure and plasma renin activity (PRA). Given late in sepsis, aprotinin caused a rapid rise in arterial pressure and SVR towards baseline levels. In cirrhosis, aprotinin increased SVR in patients with low baseline values, and improved glomerular filtration rate, renal plasma flow and sodium excretion in all subjects; PRA was suppressed by aprotinin. Aprotinin reverses pathological systemic vasodilatation in these two conditions, and this is associated with a reduction in renin release and improved renal function.
