Abstract:
This retrospective descriptive research aimed to study the structure, process and outcomes of cardiopulmonary resuscitation for out-of-hospital cardiac arrest patients undergoing treatments at the Emergency Unit, Phra Nakhon Si Ayutthaya Hospital. The samples were 91 out-of-hospital cardiac arrest patients who received resuscitation at the Emergency Unit, Phra Nakhon Si Ayutthaya Hospital and 96 healthcare workers working on resuscitation at the scene of the accident and the emergency room. The
research instruments were: 1) a record form and a test of the structure knowledge of healthcare workers, 2) a record of data on resuscitation process, and 3) a record of resuscitation outcomes. Data were analyzed using descriptive statistics.
The research results on the structure indicated that most patients were men (58.42%). The mean age was 58.37 years. (SD= 20.12) The most common cause of cardiac arrest was acute myocardial infarction (34.07%). 43.96% of patients arrived at the hospital via the emergency medical services. 89.01% of them were witnessed while they had cardiac arrest. 14.60% of them received chest compression from their witnesses before arriving at the hospital. It was also found that most of registered nurses, emergency medical technicians-intermediate officers, and emergency medical technicians-basic
officers had a good level of knowledge about resuscitation (73.33%, 62.50%, and 51.79%, respectively). With regard to the process chain of survival, it was found that the average response time was 14.43 minutes (SD= 5.76). 80% took more than 8 minutes. The duration staring from palpation to the first chest compression was less than 5 minutes (68.13%). 78.95% of patients could not be helped by electrical stimulation. The duration staring from palpation to the reception of the first dose of adrenaline was 5-10
minutes (30.77%). The duration from staring from palpation to the return of spontaneous circulation (ROSC) was more than 30 minutes (37.78%). As for the outcomes, 45 patients (49.45%) returned to have vital signs. 33 patients (36.26%) had 24-hour survival. The research recommended the provision of a training course on basic resuscitation for the general people to increase a chance of survival
