    Notes: Summary A randomized controlled clinical trial was conducted on the effects of immunoglobulin in therapy for infections in 104 intensive care patients. At the first sign of infection, one group of 50 patients received an i.v. preparation of immunoglobulin (4×100 ml) combined with antibiotics. The other 54 control patients received antibiotics alone. The most common infections in these patients were pneumonia, septicemia, peritonitis and wound sepsis. Infections were significantly seldom the cause of death, especially in patients with high-risk surgery who had been treated with immunoglobulin (p≤0.05). Likewise ventilation time in the high-risk surgery group averaged only 5.5 days for those receiving immunoglobulin as opposed to 12.7 days in controls (p≤0.01). Whereas the control group, in particular patients with pneumonia, remained in intensive care an average of 21.5 days, those receiving immunoglobulin stayed only 14.8 days (p≤0.01). In general, patients treated with immunoglobulin recovered more rapidly from infections than did controls (p≤0.01).

    Notes: Summary The present study examined the regional vascular effects (radioactive microspheres) of converting-enzyme inhibition (captopril, 1mg/kg) and calcium-antagonism (diltiazem, 1 mg/kg) in a rat model of cardiac failure due to large myocardial infarction (n=18, infarct size 40% of the left ventricle) both at rest and during submaximal tread-mill exercise. Diltiazem increased renal, gastrointestinal, coronary and cutaneous blood flow at rest by 29%, 28%, 26% and 37% (p〈0.05 each) and enhanced skeletal muscle blood flow during exercise by 16% (p〈0.05). Captopril improved primarily renal and coronary blood flow at rest (by 59% and 23%, respectively,p〈0.05) and reduced vascular resistance in the gastrointestinal bed by 25% (p〈0.05) without significant effects in other circulatory beds. We conclude that the regional vascular effects elicited by converting-enzyme inhibition and calcium antagonism differ considerably in this animal model of congestive heart failure and may be clinically important. The favourable regional vascular profile of diltiazem deserves further clinical investigation.

    Notes: Abstract Nosocomial infection rates in an old intensive care ward constructed in 1924 were compared with those in a new one constructed in 1986. The nosocomial infection rate in the old unit was 34.2% and that in the new unit 31.9%, with an average of 33%. The most frequent infections were: pneumonia, urinary tract infection, septicaemia and wound infection. After transfer of the intensive care unit (ICU) the incidence and profile of nosocomial infections remained the same. These findings suggest that the influence of architectural design has little impact on the incidence of nosocomial infections.
