    Cardiopulmonary resuscitation training in Malaysia was started at the General Hospital Kuala Lumpur in 1986. Now the programme has been extended to all the General Hospitals in the country and is fully supported by the Ministry of Health. The American Heart Association curriculum for Basic Life Support is followed. From February 1986 till March 1991, the programme has trained 3982 in Basic Life Support and 548 in Advanced Cardiac Life Support. We are making efforts to translate some of the American manuals into the National language. A preliminary survey on early defibrillation indicates that majority of the physicians will allow defibrillation by non-physician.

    BACKGROUND: There is high variability among clinicians' decision of appropriate cardiopulmonary resuscitation (CPR) duration before deciding for termination of resuscitation. This study attempted to investigate factors associated with the decision to prolong resuscitation attempts in cardiac arrest patients treated in an emergencydepartment (ED).

    METHODS: A retrospective study that evaluated two years of mortality registry starting in 2015 was conducted in the ED of University Kebangsaan Malaysia Medical Centre (UKMMC), Kuala Lumpur, Malaysia. Adult out-hospital cardiac arrest (OHCA) patients treated in the ED were included. Multivariate logistic regression analysis was utilized for the exploration of factors associated with prolonged CPR attempts (> 30min).

    RESULTS: The median CPR duration was 24min (range 2-68min). Four variables were independently associated with prolonged CPR attempts: younger age (OR, 0.97; 95% CI, 0.95-0.99; p<0.001), pre-existing heart disease (OR, 1.97; 95% CI, 1.07-3.65; p=0.031), occurrence of transient return of spontaneous circulation (ROSC) (OR, 2.38; 95% CI, 1.05-5.36; p=0.037), and access to the ED by nonemergency medical services (EMS) transport (OR, 1.92; 95% CI, 1.09-3.37; p=0.024).

    CONCLUSION: Patient-related and access-related factors were associated with prolonged CPR attempts among OHCA patients resuscitated in the ED.

    BACKGROUND: The Pan Asian Resuscitation Outcomes Study (PAROS) is a retrospective study of out- of-hospital cardiac arrest(OHCA), collaborating with EMS agencies and academic centers in Japan, South Korea, Malaysia, Singapore, Taiwan, Thailand and UAE-Dubai. The objectives of this study is to describe the characteristics and outcomes, and to find factors associated with survival after paediatric OHCA.

    METHODS: We studied all children less than 17 years of age with OHCA conveyed by EMS and non-EMS transports from January 2009 to December 2012. We did univariate and multivariate logistic regression analyses to assess the factors associated with survival-to-discharge outcomes.

    RESULTS: A total of 974 children with OHCA were included. Bystander cardiopulmonary resuscitation rates ranged from 53.5% (Korea), 35.6% (Singapore) to 11.8% (UAE). Overall, 8.6% (range 0%-9.7%) of the children survived to discharge from hospital. Adolescents (13-17 years) had the highest survival rate of 13.8%. 3.7% of the children survived with good neurological outcomes of CPC 1 or 2. The independent pre-hospital factors associated with survival to discharge were witnessed arrest and initial shockable rhythm. In the sub-group analysis, pre-hospital advanced airway [odds ratio (OR) = 3.35, 95% confidence interval (CI) = 1.23-9.13] was positively associated with survival-to-discharge outcomes in children less than 13 years-old. Among adolescents, bystander CPR (OR = 2.74, 95%CI = 1.03-7.3) and initial shockable rhythm (OR = 20.51, 95%CI = 2.15-195.7) were positive factors.

    CONCLUSION: The wide variation in the survival outcomes amongst the seven countries in our study may be due to the differences in the delivery of pre-hospital interventions and bystander CPR rates.

    INTRODUCTION: Bystander cardiopulmonary resuscitation (CPR) serves as a vital link to improve the chance of survival among the out-of-hospital cardiac arrest (OHA) patients. The frequency of bystander CPR in Malaysia is largely unknown. The aim of this study was to find out how frequently bystander CPR was performed among OHA patients with CPR performed at the Emergency Department (ED), Hospital Universiti Sains Malaysia (HUSM), prior to their arrival to the department.
    METHODS: In this one-year observational study, data was collected from cases of CPR performed in ED, HUSM. In the OHA category, a subanalysis was further performed to look into the frequency and effects of bystander CPR on achieving return of spontaneous circulation and survival to hospital admission. The categorical data collected was analysed using chi-square test or Fisher-exact test.
    RESULTS: Out of a total of 23 OHA patients that had CPR performed on arrival at the ED, HUSM, from March 2005 to March 2006, only two cases (8.7 percent) had bystander CPR performed. None of these two cases achieved return of spontaneous circulation.
    CONCLUSION: Although this study has many limitations, it does indicate that the frequency of bystander CPR is dismally low in our community and the mere fact that bystander CPR was reported to be done does not seem to translate into a higher chance of survival to admission. The quality and effectiveness of the technique is equally important.

    BACKGROUND: In out of hospital cardiac arrest (OHCA), the prognostic influence of conversion to shockable rhythms during resuscitation for initially non-shockable rhythms remains unknown. This study aimed to assess the relationship between initial and subsequent shockable rhythm and post-arrest survival and neurological outcomes after OHCA.

    METHODOLOGY: This was a retrospective analysis of all OHCA cases collected from the Pan-Asian Resuscitation Outcomes Study (PAROS) registry in 7 countries in Asia between 2009 and 2012. We included OHCA cases of presumed cardiac etiology, aged 18-years and above and resuscitation attempted by EMS. We performed multivariate logistic regression analyses to assess the relationship between initial and subsequent shockable rhythm and survival and neurological outcomes. 2-stage seemingly unrelated bivariate probit models were developed to jointly model the survival and neurological outcomes. We adjusted for the clustering effects of country variance in all models.

    RESULTS: 40,160 OHCA cases met the inclusion criteria. There were 5356 OHCA cases (13.3%) with initial shockable rhythm and 33,974 (84.7%) with initial non-shockable rhythm. After adjustment of baseline and prehospital characteristics, OHCA with initial shockable rhythm (odds ratio/OR=6.10, 95% confidence interval/CI=5.06-7.34) and subsequent conversion to shockable rhythm (OR=2.00,95%CI=1.10-3.65) independently predicted better survival-to-hospital-discharge outcomes. Subsequent shockable rhythm conversion significantly improved survival-to-admission, discharge and post-arrest overall and cerebral performance outcomes in the multivariate logistic regression and 2-stage analyses.

    CONCLUSION: Initial shockable rhythm was the strongest predictor for survival. However, conversion to subsequent shockable rhythm significantly improved post-arrest survival and neurological outcomes. This study suggests the importance of early resuscitation efforts even for initially non-shockable rhythms which has prognostic implications and selection of subsequent post-resuscitation therapy.
