In a multicenter observational study of 163 medical and surgical patients with a total of 173 episodes of sepsis or septic shock (Elebute sepsis score: 19.0 +/- 0.5), the effects of supplemental i.v. immunoglobulin (i.v. IG) treatment (unmodified polyvalent IgG pH 4.25, n = 123; for Pseudomonas sepsis, n = 50, Pseudomonas IgG) on multiple organ failure (MOF) were investigated by means of APACHE II score changes (pretreatment: 23.7 +/- 0.6). In 44% of the cases ("responders"), a prompt improvement in APACHE II score (defined as decrease greater than or equal to 4) was evident from day 0 to day 4 after onset of therapy, thus being in close time relationship to the i.v. IG administration. This improvement, associated with a better prognosis (mortality 24% vs. 55%), was found in all subgroups, most importantly the following: polyvalent IgG vs. Pseudomonas IgG treatment; medical vs. surgical patients; moderate vs. severe MOF; and gram-positive vs. gram-negative septicemia. In a small-sized second comparative nonrandomized control group (n = 27, antibiotic treatment alone) of septic patients (Elebute: 14.7 +/- 1.0) with similar MOF severity (APACHE II: 23.6 +/- 1.4), the response rate (30%) was, though not statistically significant, lower by one-third. The optimal baseline score ranges for patient inclusion into future placebo-controlled randomized i.v. IG trials were found to be 20-35 for the APACHE II score and 12-27 for the Elebute score.

Haemodynamic investigations, partly using invasive monitoring, concerning interactions between the Β-mimetic effect of fenoterol and the Α-sympathetic blockade of spinal or epidural anaesthesia were made in a total of 49 patients during pregnancy, during cae-sarean section and in non-pregnant women. Haemodynamic effects of fenoterol during regional anaesthesia were compared with those during general anaesthesia (n = 17). Epidural or spinal anaesthesia enhance vascular Β-mimetic reactions at the start of tocolysis, leading to a profound but short-lasting decrease in blood pressure. This initial hypotension is more pronounced after regional than after general anaesthesia.
