بررسی نتایج احیا قلبی-ریوی و عوامل مؤثر بر آن

Background: Cardiopulmonary resuscitation, commonly well-known as CPR, is an emergency technique that includes chest compression often with artificial ventilation in an exertion to manually preserve complete brain task until additional measures are taken to return spontaneous blood circulation and breathing in a person who is in cardiac arrest. According to the International Liaison Committee on Resuscitation Guidelines, CPR includes chest compressions for adults between 5 cm (2.0 in) and 6 cm (2.4 in) deep and at a rate of at least 100 to 120 per minute. Cardiopulmonary resuscitation is aimed to reverse vital organs as like as heart, lungs and for subsistence of patients. Several researches showed that different factors affect the resuscitation results. The current study was designed to assess the results of resuscitation and its association factors. Methods: This retrospective, descriptive and analytic study was carried out in Baharloo Hospital, Tehran, Iran during March 2014 and February 2015. In current work, all resuscitated patients were imported and patients with uncompleted files and died before entrance to hospital were excluded. The data was obtained from medical records units, office files unit and the unit of quality improvement. Data were analyzed by use of SPSS version 22 (Armonk, NY, USA) software and Chi-square test and Student’s t-test. Results: From 891 patients, 813 cases were entered the study that 498 (61.3%) were male and 315 (38.7%) were female. 41.1% of resuscitation were successful and 58/9% were unsuccessful. The mean and standard deviation time of resuscitation was 28.80 and 12.6 minutes; the most frequent primary diagnosis was cardiovascular disease. In this study there was a significant difference between age and duration of the resuscitation with successful resuscitation (P= 0.02) but, in the variables of ward and resuscitation team were not significant (P> 0.05). Conclusion: The results of this study showed that resuscitation in younger group, short duration of resuscitation and patients without heart diseases are more successful.
