Cardiopulmonary resuscitation sheets had been completed and signed by the hospital supervisor. The sheet contained information in regards to the patients’ demography including name, age, sex, time that CPR team was called in, duration of CPR,

time of working shift (day or night) and the working status of the day (holiday or working day) in which CPR was performed and the outcome of CPR. The CPR sheets had been reviewed and verified by the nursing offices after CPR. The success ratios (successful CPR/unsuccessful CPR) were compared using Z (Binomial) and -tests and Statistical Package for Social GDC-0068 solubility dmso Sciences (SPSS 17). A P value of Inhibitors,research,lifescience,medical ≤0.05 was considered statistically significant. Results Data were obtained from CPR sheet of 2262 patients who were cardiopulmonary resuscitated from 2001-2008 at Baghiatollah hospital, Tehran, Iran.The number of female patients was 975 (43%), and that of male patients

was 1287 Inhibitors,research,lifescience,medical (57%). The cardiopulmonary arrests in 281(12.4%) of patients were of cardiac origin, in 312 (13.8%) of cases were due to respiratory problems, and in 1669 (73.8%) patients were the result of both cardiac and pulmonary problems. Cardiopulmonary resuscitation was successful in 741 (32.8%) of patients. The ages of the patients were 56.4±17.9 years. One hundred sixty four (7.25%) patients were under 15 years, 94 (4.15%) were between Inhibitors,research,lifescience,medical Inhibitors,research,lifescience,medical 15 to 29 years, 133 (5.87%) were between 30 to 44 years, 476 (21.04%) were between 45 to 60 years, and 1395 (61.67%) were above 60 years. The number of successfully cardiopulmonary resuscitated cases in patients with over 60 years of age (n=529)

was significantly (P<0.001) higher than that in patients with ages of below 60 years (n=212) (table 1). The number of CPR cases performed during long-day shift (7:00 to 19:00) were 1825, and the number of those performed during night shift (19:00 to 7:00) were 437. The number of successful CPR cases in long-day shift was 523, which was Inhibitors,research,lifescience,medical more than twice that in the night shift (n=218) (table 1). Furthermore, 413 (18.4%) cases were resuscitated on holidays and 1849 (81.7%) on the working days. The number of successful CPRs in working days was 577, which was about 3.5 times the successful CPR cases (164) on holidays (table 1). Table 1 The number and percentage Cediranib (AZD2171) of successful, unsuccessful and total CPR cases based on the patients’ ages, working shifts and working days The duration of CPR was 10 min or less in 710 (31.4%) cases, (11–20) min in 382 (16.9%) cases, (21–30) min in 632 (27.9%) cases, and above 30 min in 538 (23.8%) cases. There was a significant (P=0.001) difference between the number of successful cases whose CPR durations were above and below 10 min (table 2). There were 741 successful cases, of which 212 cases (24.5%) were below 60 years and 529 cases (37.9%) were above 60 years (table 2).
