Resuscitation

Although modern defibrillators are nearly always successful in terminating ventricular fibrillation (VF), multiple defibrillation attempts are usually required to achieve return of spontaneous circulation (ROSC). This is potentially deleterious as cardiopulmonary resuscitation (CPR) must be discontinued during each defibrillation attempt which causes deterioration in the heart muscle and reduces the chance of ROSC from later defibrillation attempts. In this work defibrillation outcomes are predicted prior to electrical shocks using a neural network model to analyse VF time series in an attempt to avoid defibrillation attempts that do not result in ROSC. ⋯ Pre-shock VF ECG time series can be classified according to the defibrillation conversion to a return of spontaneous circulation (ROSC) or No-ROSC.

Comparative Study
A study comparing the usability of fully automatic versus semi-automatic defibrillation by untrained nursing students.
Current international guidelines prefer the use of semi-automatic external defibrillators (SAEDs) over fully automatic external defibrillators (FAEDs). However, there is a lack of evidence supporting this recommendation. We conducted a study of usability with nursing students comparing the FAED version against the SAED version of the Lifepak CR Plus AED (Medtronic, Redmond, USA). We hypothesized that FAED use would limit the number of operator-device interactions, thereby increasing compliance by the rescuer, safety and speed. ⋯ Despite a lack of BLS skills and AED training, the majority of students demonstrated safe and effective use of the AED. The use of the FAED version of the CR Plus resulted in increased compliance with the protocol and reduced variability in time to deliver three shocks. Further research is needed to confirm these findings in other groups of first responders.

Resuscitation skills are a fundamental part of anaesthetic practice. Anaesthetists are involved in performing resuscitation and training of other staff in resuscitation techniques. ⋯ The results show that although they are involved in training, very few attend cardiac arrests. Most have not, and will not, attend the ALS course but would prefer shorter regular resuscitation updates, especially in those skills that they no longer use.

Although the long term success of cardiopulmonary resuscitation (CPR) is still less than hoped for, its value cannot be questioned when carried out appropriately in selected cases. Resuscitation frequently brings only short-term success, and several patients suffer severe consequences also causing an economic, medical and ethical burden to society. The issue of limitation of resuscitation, including Do Not Attempt Resuscitation (DNAR) and the termination of resuscitation has been surveyed in many European countries using a structured questionnaire. In Hungary no such comprehensive study has been conducted yet. The goal of this investigation was to recognise the ethical factors limiting resuscitation in Hungary. ⋯ The results underline the original presumption that the Hungarian resuscitation practice is at first influenced by professional (or "thought to be professional") standpoints. The quality of life, and patient autonomy plays an important role in the decision making about limitation of resuscitation efforts. Current CPR education emphasizes the importance of ethical considerations, and this could be observed clearly in the answers.
