The observation on clinical effect of "Bian Que flying rescue" system for patients with chest pain in pre- hospital care / 中国医学装备

ABSTRACT

Objective:To explore the clinical effect of "Bian Que flying rescue" system for patients with chest pain in pre-hospital care.Methods:160 patients with acute chest pain were randomly divided into observation groups (80 cases) and control group (80 cases). The patients of observation group received the treatment of "Bian Que flying rescue" system and the patients of control group received the routine pre-hospital emergency measures. A series of indicators including the diagnosis time of pre-hospital, the time span between attack and beginning treatment, clinical curative effect, occurrence of complication and hospital stay time were compared and recorded.Results:The diagnosis time of pre-hospital, diagnosis time of intra-hospital and the time between attack and beginning treatment of observation group were significantly shortened, and the differences of these indicators between two groups were significant (t=14.095,t=9.997,t=4.230,P<0.05), respectively. The numbers of the attack of various complication of observation group were significantly reduced, and the differences of cardiac failure, cardiogenic shock, malignant arrhythmia and myocardial infarction between the two groups were statistically significant (x2=10.230,x2=9.141, x2=5.223,x2=5.096,P<0.05).And the prognosis of observation group was significantly enhanced, and the number of die in one week was significantly reduced, and the differences of these indicators between the two groups were significantly(x2=12.172,P<0.05). Besides, the time of hospital stay and the total cost of hospital stay of observation group were, respectively, significantly shortened and decreased, and the left ventricular ejection fraction (LVEF) of observation group was significantly increased. And the differences of all of these indicators between the two groups were statistically significant(t=4.022,t=4.495,t=9.047,P<0.05).Conclusion: "Bian Que fling rescue" system which was applied in the first aid outside of hospital for patients with chest pain can significantly improve the success rate of rescue, and reduce case fatality rate and the occurrences of complications including congestive heart failure and cardiogenic shock, and shorten the time of therapy, and increase economic efficiency of hospital. It has a certain clinical application value.
