The serum concentration of cardiac enzymes may be influenced by mechanical and electrical trauma due to cardiopulmonary resuscitation (CPR) attempts. This could complicate the determination of whether an acute myocardial infarction (AMI) had occurred. In this study, only patients without any of the known confounding factors affecting cardiac enzyme release were included, and the specific time course and patterns of serum cardiac enzyme levels after resuscitation were evaluated. The purpose is to help clinicians distinguish between spontaneous myocardial damage and that induced by CPR. ⋯ In this study, the influence of resuscitative procedures - defibrillation excluded - on the release of cardiac enzymes were examined. During 30 h after ROSC cTnI level exhibited a bell-shaped configuration, which is distinct from that after AMI; whereas the enzymatic activities of CKMB and CK, as well as CKMB/CK ratio, were constantly higher than normal. This chronological pattern of cardiac enzyme levels may help physicians differentiate primary cardiac disease from other aetiologies in out-of-hospital cardiac arrests.

Honey intoxication, a kind of food poisoning, can be seen in the Black Sea region of Turkey and in various other parts of the world as well. In this study, 66 patients were hospitalized with a variety of symptoms including nausea, vomiting, salivation, dizziness, weakness, hypotension, bradycardia and syncope several hours after the ingestion of small amounts of honey. ⋯ These features resolved completely in 24 h with i.v. fluids and atropine, and none died. In conclusion, honey poisoning should be taken into consideration in the differential diagnosis of acute myocardial infarction and in the patients with vomiting, hypotension and bradycardia.

Studies show that nurses retain resuscitation skills poorly and that retention of ventilation skills is particularly difficult. We formed the hypothesis that the SMART BAG (SB, O-Two Medical Technologies Inc., Canada), i.e. a bag-valve-mask device with a pressure/flow responsive valve, would assist nurses in providing more efficient ventilation six months after training. ⋯ Six months after training, nurses ventilated at least as efficiently with the SB, compared with the STBVM. This illustrates the ability of the SB to compensate for the deterioration over time in skill. On the other hand, training with a STBVM should focus primarily on prolonging the inspiratory time, and therefore the peak pressure, whilst maintaining an adequate Vt.

Comparative Study
The effects of teaching basic cardiopulmonary resuscitation--a comparison between first and sixth year medical students.
The purpose of this study was to check if medical students of one of the Universities of Medical Sciences in Poland are prepared to do basic cardiopulmonary resuscitation. The research was undertaken on groups of 50 first year students and 50 sixth year students at the time when they take an exam. To have wider insight into students' ability to perform basic cardiopulmonary resuscitation, quantitative and qualitative methods were used. ⋯ The study showed that skills of ventilation and chest compressions need more practice. The students' own estimation of the ability to perform cardiopulmonary resuscitation both in the first and sixth years is very high, but it does not correlate with their knowledge and skills. Our conclusions indicate the need to improve the programme of teaching cardiopulmonary resuscitation with a refresher course in theory and skills at least once a year.
