The aim of our study was to compare poly(ADP-ribose) polymerase (PARP) activity levels in a porcine model of hemorrhagic shock and resuscitation. ⋯ In our model of porcine hemorrhagic shock, PARP activity levels increased during hemorrhagic shock. However, this increase in PARP activity levels was transient as they returned to baseline regardless of resuscitation strategy. Interestingly, PARP activity levels were significantly higher during hemorrhagic shock in non-survivors compared to survivors. These findings suggest that PARP activity may be a part of initial pathways leading from hemorrhagic shock to death.

Cerebral blood flow (CBF) during cardiopulmonary resuscitation and after restoration of spontaneous circulation (ROSC) from cardiac arrest has previously been measured with the microspheres and laser Doppler techniques. We used positron emission tomography (PET) with [15O]--water to map the haemodynamic changes after ROSC in nine young pigs. After the baseline PET recording, ventricular fibrillation of 5 min duration was induced, followed by closed-chest cardiopulmonary resuscitation (CPR) in conjunction with IV administration of three bolus doses of adrenaline (epinephrine). ⋯ CBF was measured at intervals during 4h after ROSC. Relative to the mean global CBF at baseline (32+/-5 ml hg(-1)min(-1)), there was a substantial global increase in CBF at 10 min, especially in the diencephalon. This was followed by an interval of cortical hypoperfusion and a subsequent gradual return to baseline values.

Early initiation of bystander cardiopulmonary resuscitation (CPR) improves the chances of successful resuscitation and survival. The importance of bystander CPR is attracting more interest, and there has been an increase in attendance at CPR training courses in Japan. However, there have been few reports regarding Japanese attitudes toward the performance of bystander CPR. The present study was performed to identify current Japanese attitudes toward bystander CPR compared to our previous study performed in 1998. ⋯ Most laypeople and health care providers are unlikely to perform CC plus MMV, especially on a stranger or trauma victim, but are more likely to perform CC only, as also found in our previous study in 1998. These findings suggest that MMV training should be de-emphasised and the awareness of CC alone should be emphasised because, for whatever reason, people do not want to perform MMV.
