Resuscitation

Transport of patients during resuscitation is a critical procedure. In both, ambulances and helicopters the quality of resuscitation is potentially hampered due to the movement of the vehicle and confined space. To date, however, no direct comparison of the quality of resuscitation at the scene, during a helicopter flight and in a moving ambulance has been made. ⋯ Resuscitation during transport is feasible and relatively efficient. There is some difference between the environments, but there is no relevant difference between helicopters and ambulances regarding the effectiveness of CPR.

Extracorporeal life support has been used as an extension of conventional cardiopulmonary resuscitation (CPR). However, the appropriate indications for extracorporeal CPR (ECPR) including the duration of CPR are unknown. We present a case of a male, 37-year-old out-of-hospital cardiac arrest patient who received prolonged CPR followed by ECPR. ⋯ Ultimately, the patient was discharged without neurological complications. Although cardiac arrest occurred out-of-hospital and CPR was performed for a long time, a patient might be a candidate for ECPR if perfusing rhythms are restored transiently but not successfully maintained due to recurrent VF. ECPR may be used for VF unresponsive to standard CPR techniques.

Cardiopulmonary resuscitation (CPR) for 10-30 min without return of spontaneous circulation is considered to have a grave prognosis. We report a 27-year-old woman who experienced in-hospital, witnessed cardiac arrest and underwent prolonged CPR with manual chest compressions for 280 min. Adequate chest compression was monitored with femoral arterial pressure monitoring. ⋯ She was then supported with extracorporeal membrane oxygenation (ECMO) for 9 days without her heart beating. After combined heart and kidney transplantation, she recovered well with intact cerebral performance. This successful case report supports the endeavours for relentless CPR efforts.

Targeted defibrillation therapy is needed to optimise survival chances of ventricular fibrillation (VF) patients, but at present VF analysis strategies to optimise defibrillation timing have insufficient predictive power. From 197 patients with in-hospital and out-of-hospital cardiac arrest, 770 electrocardiogram (ECG) recordings of countershock attempts were analysed. Preshock VF ECG features in the time and frequency domain were tested retrospectively for outcome prediction. ⋯ Using frequency band segmentation of human VF ECG, several single predictive features with high ROC AUC>0.840 were identified. Combining these single predictive features using neural networks did not further improve outcome prediction in human VF data. This may indicate that various simple VF features, such as median slope already reach the maximum prediction power extractable from VF ECG.

Recent studies have found that poor cardiopulmonary resuscitation (CPR) is commonly performed in resuscitation attempts, both by health professionals and lay people. One of the contributing factors to poor performance of CPR may be poor initial teaching. This study was conducted to investigate the quality of 14 CPR courses complying with New Zealand Qualifications Authority standards, which includes formal assessment of CPR. ⋯ Importantly, in the majority of courses (71%), certification was granted when the CPR technique was performed incorrectly, with both compression depth and compression place being corrected only 57% of the time. Courses only discussed the importance of early defibrillation 57% of the time, and provided limited information on symptoms of acute coronary syndromes. In light of these observations it is suggested that the current style of teaching is unlikely to result in students being able to perform adequate CPR if required in the community.
