Resuscitation

To evaluate the impact of decreased fluid resuscitation on multiple-organ dysfunction after severe burns. This approach was referred to as "permissive hypovolaemia". ⋯ Permissive hypovolaemia seems safe and well tolerated by burn patients. Moreover, it seems effective in reducing multiple-organ dysfunction as induced by oedema fluid accumulation and inadequate O2 tissue utilization.

After successful cardiopulmonary resuscitation, acute ST-elevation myocardial infarction (STEMI) may be documented. We investigated the incidence and prognosis of patients admitted to our department between 1 January 2000 and 31 December 2004. Among 2393 consecutive patients with STEMI, 135 (5.7%) presented after a return of spontaneous circulation (ROSC). ⋯ Hospital survival among comatose patients was 51% and hospital survival with cerebral performance category (CPC) 1 or 2 was 29%. Accordingly, outcome of patients with STEMI who regain consciousness after ROSC and undergo primary PCI is comparable to patients without cardiac arrest. This is in contrast with comatose survivors who, despite aggressive reperfusion treatment, had a significantly worse outcome.

The present study was undertaken to compare an animal model of electrically induced VF with ischemically induced VF. In a preponderance of models of cardiac arrest and resuscitation in intact animals, ventricular fibrillation (VF) is induced by an alternating current delivered directly to the epicardium or endocardium. Yet, the applicability of such animal models has been challenged for it is not an electrical current alone but rather a current generated in the ischemic myocardium that triggers VF. Accordingly, a potentially more clinically relevant model was investigated in which spontaneous VF followed acute myocardial ischemia. ⋯ A significant increase in the number of post-resuscitation premature ventricular beats and recurrent VF followed ROSC and a significantly greater number of shocks was required for restoration of spontaneous circulation (ROSC) after LAD occlusion. Nevertheless, early post-resuscitation myocardial dysfunction, neurological recovery and 72 h survival were indistinguishable between the two models.
