Recent advances in external cardiac defibrillation techniques / 生物医学工程学杂志

As an important medical electronic equipment for the cardioversion of malignant arrhythmia such as ventricular fibrillation and ventricular tachycardia, cardiac external defibrillators have been widely used in the clinics. However, the resuscitation success rate for these patients is still unsatisfied. In this paper, the recent advances of cardiac external defibrillation technologies is reviewed. The potential mechanism of defibrillation, the development of novel defibrillation waveform, the factors that may affect defibrillation outcome, the interaction between defibrillation waveform and ventricular fibrillation waveform, and the individualized patient-specific external defibrillation protocol are analyzed and summarized. We hope that this review can provide helpful reference for the optimization of external defibrillator design and the individualization of clinical application.

Assessment Of Knowledge And Awareness Of Adult Basic Life Support Among Post Graduate Students Of Rama Dental College, Kanpur City, India.

Background: Accidents and cardiac arrest are mostly encountered life threatening emergencies, which can sometimes be prevented by adequate knowledge and proper practice regarding basic life support (BLS) and resuscitation. Therefore, the study aims at evaluating the knowledge and awareness of adult basic life support among postgraduate students of Rama Dental College, Kanpur. Methodology: A cross- sectional descriptive study was been conducted amongst the postgraduate students regarding BLS. Permission was obtained from the Institutional heads and the review board. A self- structured questionnaire in English which was administered was validated via pilot study. The questionnaire comprised of 13 close ended questions including demographic details as well as questions regarding knowledge and awareness on Basic Life Support. A single calibrated examiner administered the questionnaire. Statistical analysis was done by calculating percentage and frequency distribution. Results: 100 postgraduate students were chosen as study subjects. Out of those, 95 students submitted the duly filled questionnaires. Therefore, it was seen that only 37%-38% students had knowledge regarding the meaning of BLS, while only 11% postgraduate students were aware of the latest modification of the BLS. 30%-37% students gave the correct response for the question ‘first response when you see a person unresponsive on road’. 56% students had knowledge regarding the location for compression of chest. Conclusion: In the current study, we found that most of the postgraduate students did not have adequate knowledge regarding BLS.

Cardiopulmonary resuscitation:current status and future / 第二军医大学学报

Cardiac arrest has high morbidity and mortality and is hard to be accepted by family members.It is related to a series of economy and social problems.Resuscitation science is aimed to study the epidemiology,pathophysiology,mechanisms,and management of the sudden states of illnesses or injuries which result in impending or actual cessation of oxygen delivery.After 40 years research,the current hot issues in this area included cell injury,the role of automatic external defibrillation and mild therapeutic hypothermia.Research on these focuses will improve survival rate after cardiopulmonary resuscitation.
