Insights
Sudden cardiac arrest survival rates improved with prompt cardiopulmonary resuscitation (CPR) and specific causes. In-hospital cardiac arrest and cardiopulmonary arrest causes were linked to better outcomes in Thailand.
Area of Science:
- Emergency Medicine
- Cardiology
- Public Health
Background:
- Sudden cardiac arrest (SCA) presents a critical emergency with low survival rates globally.
- Survival outcomes depend on patient characteristics, pre-hospital factors, and resuscitation details.
- Limited data exists on SCA survival in Thailand and other Asian countries.
Purpose of the Study:
- To evaluate factors influencing survival and outcomes in cardiac arrest patients receiving cardiopulmonary resuscitation (CPR).
- To determine the survival rate of cardiac arrest patients at Ramathibodi Emergency Medicine Department.
- To address the data gap concerning cardiac arrest in Thailand.
Main Methods:
- Retrospective study of patients over 15 years old with sudden cardiac arrest from January 2005 to December 2010.
- Inclusion of patients resuscitated in the emergency room.
- Analysis using descriptive statistics and logistic regressions for sustained return of spontaneous circulation (ROSC) and survival at discharge.
Main Results:
- Overall sustained ROSC rate was 34.8%; survival at discharge was 11.1%.
- Out-of-hospital cardiac arrest (145 patients): survival 52.4%, survival to discharge 7.6%.
- In-hospital cardiac arrest (36 patients): survival 86.1%, survival to discharge 25.0%.
- Factors for sustained ROSC included good/moderate cerebral performance, in-hospital arrest, CPR within 30 minutes, and cardiopulmonary cause.
- Cardiopulmonary cause of arrest influenced survival to discharge.
Conclusions:
- Sustained ROSC is associated with pre-arrest functional status, arrest location, CPR duration, and cause.
- Survival to discharge is primarily related to the cause of cardiac arrest.
Purpose:
Sudden cardiac arrest is a common emergency condition found in the emergency department of the hospital. The survival rate of out-of-hospital cardiac arrest patients is 2.0%-10.0% and 7.4%-27.0% percent for in-hospital cardiac arrest patients. The factors for survival outcome are divided into three main groups: patient characteristics, pre-hospital factors, and resuscitated information. The objective of this study was to evaluate the related factors, outcome, and survival rate in patients with cardiac arrest who received cardiopulmonary resuscitation (CPR) at Ramathibodi Emergency Medicine Department. There are limited data for this issue in Thailand and other Asian countries.
Methods:
This retrospective study included all patients who were older than 15 years with sudden cardiac arrest and who were resuscitated in the emergency room between January 2005 and December 2010. Descriptive analytic statistics and logistic regressions were used to analyze factors that related to the sustained return of spontaneous circulation (ROSC) and survival at discharge.
Results:
There were 181 patients enrolled. The overall sustained ROSC rate was 34.8% and the survival rate at discharge was 11.1%. There were 145 out-of-hospital cardiac arrest patients, in whom the survival rate was 52.4% and the survival to discharge rate was 7.6%. For inhospital cardiac arrest, there were 36 patients with a survival rate of 86.1% and the survival to discharge rate was 25.0%. Statistically significant factors related to sustained ROSC were good and moderate cerebral performance, in-hospital cardiac arrest, beginning of CPR in less than 30 minutes, and cardiopulmonary cause of arrest. The factors influencing survival to discharge were cardiopulmonary causes of cardiac arrest.
Conclusion:
Factors associated with sustained ROSC were functional status before cardiac arrest, location of cardiac arrest, duration of CPR, and cause of cardiac arrest. Survival rate was related to the cause of cardiac arrest.
