The purpose of this study was to observe the interactions between cardiac index (CI), stroke volume index (SVI), central venous pressure (CVP), intra-abdominal pressure (IAP) and total circulating blood volume index (TBVI) during resuscitation of major burns. Sixteen patients with an average TBSA of 46% (26-67%) and an average abbreviated burn severity index of 8.9 (7-11) were included into an intra-individual comparative prospective study over an 18-month period. The COLD Z-021 system (Pulsion Medical Systems, Munich, Germany) was used to obtain CI, SVI and TBVI. ⋯ Thus, the CVP is not a suitable tool to guide fluid resuscitation during burns with shock. The TBVI may be an ideal value to guide resuscitation because the augmentation of TBVI during fluid resuscitation correlated well with improved cardiac output and stroke volume. Future randomised studies are required to demonstrate whether TBVI guided resuscitation of burns has an impact on outcome.

To determine the number of CPR trained adults in Sweden, and the willingness of the non-trained population to attend a CPR course. An additional purpose was to investigate differences related to sex, age, residential area, socio-economic classification and country of origin. ⋯ Somewhere between 30 and 45% of the adult population of Sweden had participated in CPR training. Half of the non-trained population was willing to learn CPR but frequently did not know that such courses existed or where they were held. Elderly people, people of foreign origin, or those not included in the workforce were less likely to have participated in CPR training.

To determine the opinion of head teachers on the educational and logistical characteristics required for a basic cardiopulmonary resuscitation (b-CPR) programme for secondary school teenagers to succeed. ⋯ In Barcelona, most secondary schools surveyed were highly interested in a b-CPR programme for their teenagers in grades 3 or 4. Teachers would prefer healthcare providers to give the programme but would be willing to teach b-CPR theory if trained previously.

The fundamental goal of cardiopulmonary resuscitation (CPR) is recovery of the heart and the brain. This is best achieved by (1) immediate CPR for coronary and cerebral perfusion, (2) correction of the cause of cardiac arrest, and (3) controlled cardioplegic cardiac reperfusion. Failure of such an integrated therapy may cause permanent brain damage despite cardiac resuscitation. ⋯ Recovery without adverse neurological outcomes is possible in a large number of cardiac arrest victims following prolonged manual CPR. Therapy is directed toward maintaining a monitored peak BP above 60 mmHg, determining the nature of the cardiac cause, and correcting it with controlled reperfusion to preserve function.

Studies have demonstrated that perfluorocarbon (PFC) emulsions associated with hyperoxia improved whole body oxygen delivery during resuscitation of acute haemorrhagic shock (HS). Nevertheless the microcirculatory effects of PFC and the potential deleterious effects of hyperoxic reperfusion are still of concern. We investigated (i) the ability of a newly formulated, small sized and highly stable PFC emulsion to increase skeletal muscle oxygen delivery and (ii) the effect of hyperoxic reperfusion on skeletal muscle metabolism after a brief period of ischaemia using an original, microdialysis-based method that allowed simultaneous measurement tissue oxygen pressure (PtiO2) and interstitial lactate and pyruvate. ⋯ In addition, PtiO2 values increased linearly with decreasing haematocrit (Hct) values in PFC-resuscitated animals and decreased linearly with decreasing Hct values in Gelofusine-resuscitated animals. There were no differences between the two groups concerning the blood and interstitial lactate/pyruvate ratios suggesting no deleterious effect of hyperoxic resuscitation in skeletal muscle. In conclusion these results suggest that resuscitation of severe, but brief, HS with PFC increased skeletal muscle oxygen delivery without measurable deleterious effects.
