MAP 40 mm Hg for 60 min and nortnothermic fluid resuscitation: and group IV, HS at MAP 40 mm Hg for 60 min, PHCA for 60 min. and resuscitation. Controlled ventilation was maintained for at least ‘0 h and intensive care for 72 h. Results: In groups 1 and II, two of tive dogs in each group survived to 72 h. In groups III and IV, all ten dogs survived. All survivors were functionally normal, with neurologic deficit scores (OX= normal. 100%= brain dead) of < 10% Light microscopic scoring of 18 brain regions revealed no ischemic changes. All nonsurvivors had a severe metabolic acidemia after HS

Cytokine 1996; 8,2: 121 129 A murine model of haemorrhagic shock was used to investigate bacterial translocation from the gut and subsequent systemic immunoreduction. Anaesthetized mice were bled from the femoral artery. and held at a mean arterial blood pressure of 35 mm Hg for one hour then resuscitated with shed blood and two-fold volume lactated Ringer’s solution. Upon awakening, they were given cytokineb or control media orally. Bacteriological cultures of livers. spleens and mesenteric lymph nodes from haemorrhaged mice given cytokine had significantly fewer bacteria;gm of tissue than those given media. Recombinant IL-6 mimicked the effects seen with crude cytokines. Reduction of proliferation among spleen cells from hdemorrha&ed mice was observed and could be partially returned to normal by cytokine feeding. Mixing experiments in which cells from haemorrbaged mice were added to those of normal mice in an MLR showed no suppressor activity. Flow cytometry analysis revealed a reduction in CD 3 t cells at 16 h post-haemorrhage in mice fed control media or cytokines, suggesting that reduced proliferative capacity may be due to loss of function rather than active suppression. Histological examination of the intestines of haemorrhaged mice fed cytokines or media revealed restoration of intestinal mucosal integrity by cytokine administration. These results suggest that oral administration of IL-6 may be an important treatment for the prevention of systemic sepsis following haemorrhage.

Am J Cardiol 1096: 77:X: 581 585 The aim of the study was to describe the course of serum creatine kinase (CK) and its MB fraction (CK-MB) in patients surviving cardiac arrest. and to identify factors influencing CK and CK-MB release.The study was set in the community of Vienna, Austria. Data concerning cardiopulmonary resuscitation, collected within a period of 33 months, were evaluated retrospectively and compared with laborator) blood investigations collected prospectively (on admission and after 6, 12, and 24 h) in I07 adult patients surviving a witnessed cardiac arrest for 24 h. CK and CK-MB were elevated in > 75% of the patients within 24 h. Release of CK and CK-MB was mainly

Of patients with electrocar(I/ had an elevated CK-MB <‘K diographic evidence of AMI, only 49,~) ratio. In conclusion, the elevation in serum CK and CK-MB fraction in patients after nontraumatic cardiac arrest is a trcqucnt finding, and is associated with ischemic myocardial injury. .IS well as physica! trauma to the chest.
