Comparative Study
The effects of plasma and albumin infusion on organ function and sepsis markers in experimental gram-negative sepsis.
To study the effects of early plasma versus albumin infusion on vital organ function and the appearance of central sepsis mediators in septic shock, three groups of anesthetized piglets (n = 28) were inoculated with live Eschericia coli. Group I received fresh frozen plasma, group II received albumin, whereas group III served as nontreated septic controls. Plasma-treated animals exhibited improved survival (p < .02) compared with controls, and improved organ function compared with both controls and albumin-treated animals. ⋯ Following albumin infusion TNF levels decreased to baseline values (p < .01), whereas endotoxin and TCC levels did not change significantly. Our study shows a beneficial effect of early plasma infusion on survival and vital organ function in septic animals. The effect of plasma infusion on circulating levels of endotoxin, TNF, and TCC may be potentially deleterious in uncompensated stages of septic shock.

Painful episodes are the most frequent complaints of patients with sickle cell disease. The Emergency Department (ED) has provided management for acute events using the usual triage format for emergencies. A prospective study evaluated the role of the ED in the care of adults with sickle cell disease (SCD). ⋯ Absolute indications for admission include sepsis, fever >102 degreeF, white cell counts >20 000, worsening anemia, hypoxemia, acute chest syndrome and new CNS events. Patient database in the ED must be revised annually to avoid extensive workup in the ED and a complete history/physical examination, and a CBC could be sufficient for triage in an uncomplicated pain crisis. An acceptable protocol for care should be available at all EDs and a registry and information system for SCD will discourage overutilization of investigational tests and visits to multiple EDs.

A 45-year-old man died 2 months after being bitten on the hand by a dog. He developed the rare but characteristic clinical picture of fulminant septicaemia and peripheral gangrene caused by a Gram-negative bacillus, Capnocytophaga canimorsus, previously known as dysgonic fermenter type 2 (DF-2), which is an occasional commensal in the oral flora of dogs and cats. This disease must be anticipated and dog bites appropriately managed to avoid the mortality associated with infection by this micro-organism. Initial treatment includes appropriate prophylactic antibiotics and debridement, while early exchange transfusion and emergency amputation may be of value in fulminant cases.

To investigate colon anastomotic healing in an experimental model of sepsis. ⋯ Sepsis impairs healing of the colon, reflected by decreased bursting pressure and collagen concentration. The decrease in bowel wall structural collagen may affect the ability of the gut to hold sutures and thus may lead to more anastomotic failure.
