To examine whether induced hypothermia could prolong short-term survival after volume-controlled hemorrhagic shock (HS). ⋯ In lightly anesthetized pigs during volume-controlled HS, induced hypothermia may prolong their short-term survival for reasons that remain to be clarified.

To evaluate the effects of hypertonic saline (HS) and/or hydroxy ethyl starch (HES) on myocardial perfusion pressure (MPP) and blood flow (MBF), and cardiac index (CI) during and after cardiopulmonary resuscitation (CPR). ⋯ Hypertonic solutions (HS and HHS) applied during internal cardiac massage enhanced MBF and significantly increased resuscitation success and survival rate. Addition of HES to HS did not further improve the positive haemodynamic effects of HS alone.

Oxygen deficiency during critical illness may cause profound changes in cellular metabolism and subsequent tissue and organ dysfunction. Clinical treatment in these cases targets rapid reoxygenation to avoid a prolonged impaired synthesis of cellular high-energy phosphates (ATP). However, the effect of this therapeutic intervention on tissue metabolism has not been determined yet. ⋯ During hypoxia, the interstitial lacate/pyruvate ratio in groups 1 and 2 increased to 455+/-199% (muscle), 468+/-148% (intraperitoneal), 770+/-218% (hepatic) and 855+/-432% (subcutaneous) (P<0.05 vs. control, respectively). No significant inter-organ or inter-group differences in interstitial dialysates were observed in the treatment groups, neither during hypoxia nor during reoxygenation. Our data suggest, that hypoxia induces comparable metabolic alterations in various tissues and that reoxygenation with 100% oxygen is not superior to 21% oxygen in restoring tissue metabolism after critical hypoxia.
