Abstract:

ＯｂｊｅｃｔｉｖｅTo study the status of 335 patients who showed cardiac arrest and received cardiopulmonary resuscitatian (CPR), and to investigate the clinical characteristics to improve the success rate of CPR.ＭｅｔｈｏｄｓA restrospective study was carried out in 335 patients who showed cardiac arrest. According to the age, the patients were divided into two groups. The success rates of return of spontaneous circulation (ROSC) and cerebral resuscitation were compared between two groups. The starting time of CPR, the starting time of the establishment of artificial airway, defibrillation time and the dose of adrenalin were analyzed and compared.ＲｅｓｕｌｔｓThe success rate of ROSC was 2092%, while the cerebral resuscitation rate was only 065% in the elderly group, compared with 3242% and 385% in nonelderly group. There was significant difference in adrenalin dose(P＜005), while no significant difference in the starting time of the establishment of artificial ventilation and CPR, CPR lasted time and defibrillation times (P＞005) between two groups.ＣｏｎｃｌｕｓｉｏｎｓThe success rate of CPR is poor especialy in the elderly. The key to improve CPR is to emphasize the underlying disease, strengthing the emergency medical service system.
