Meta Analysis
Reporting approval by research ethics committees and subjects' consent in human resuscitation research.
To determine how frequently reports of research in human cardiopulmonary resuscitation mention approval by a research ethics committee and address subjects' consent. ⋯ Reports of resuscitation research have not consistently mentioned approval from a research ethics committee or addressed subjects' consent for interventional studies using human subjects. However, they are doing so more frequently in recent years as journal requirements for reporting change. REC approval is now almost always being reported, but subjects' consent is often not addressed. Journal editors and reviewers should ensure that authors adhere to the journal's instructions about reporting ethical conduct of experiments.

This study was designed to test the effects of active compression-decompression (ACD) versus standard (STD) cardiopulmonary resuscitation (CPR) on hemodynamics after prolonged cardiac arrest (CA). ⋯ In our study, a comparison of STD and ACD CPR revealed no significant differences in coronary perfusion pressures and ETCO2. We conclude that after prolonged CA, ACD CPR does not provide an apparent hemodynamic advantage over STD CPR.

A retrospective review of consecutive admissions (n = 285) to a university hospital intensive care unit (ICU) following cardiopulmonary resuscitation was conducted to determine long-term outcome, length of stay (LOS), and ICU resource consumption. Ninety-four patients (33%) survived to hospital discharge. ⋯ Most patients returned to their pre-arrest homes functionally independent and 58% of hospital survivors were alive 2 years after discharge. It is possible that attempts to appropriately limit therapy in patients with poor prognosis may help direct resources towards patients who will benefit.

Observers trained in basic life support assessed chest rise in 34 patients who were anaesthetised and paralysed and whose lungs were being mechanically ventilated prior to routine surgery. Making 67 independent assessments, the observers indicated the tidal volume that they considered produced adequate chest rise for resuscitation. The mean tidal volume perceived to be adequate was 384 ml with 95% confidence limits of 362-406 ml. ⋯ In the light of present knowledge and the findings in this study, we would recommend that resuscitation training manikins are recalibrated to indicate satisfactory ventilation at tidal volumes of 400-600 ml. These volumes should reduce the risk of gastric inflation and permit more chest compressions to be carried out in a minute because the ventilation fraction of the CPR sequence is shorter. Adequate CO2 elimination should still be assured.
