RESUMEN
Objective To investigate the effects of application and clinical value of the epinephrine with graduate increased dosage by the modality equation G=(K+2n-1)mg/3 min(K=1,2,n=1,2,3……,G≤0.2 mg/kg)and aminophylline and sheng-mai injection with uniform method at the same time rapidly combination on cardiopulmonary resuscitation (CPR).MethodsThree hundred and twenty-eight cases with sudden cardiac-arrest (CA) were randomly divided into 3 groups：112 cases with the standard-dose epinephrine group (SDE control group);106 cases with the first-dosage epinephrine for K=1 mg in the equation G=(K+2n-1)mg/3min (K=1,2,n=1,2,3……,G≤0.2 mg/kg,group (equation 1 group) and 110 cases with the first-dosage epinephrine for K=2mg(epuation 2 group).Patients'electrocardiogram and mean arterial pressure(MAP)and the heart rate(HR)and the time of recovery of spontaneous circulation (ROSC)were monitored,and the resuscitation effect were evaluated.ResultsTo compare the equation 2 group and equation 1 group with the SDE control group,the ROSC rate,the survival rate,the 24-hour survival rate and the scoring by Glasgow coma scale were all significantly elevated(P＜0.01)：but the average time from initial stage applied with the epinephrine in the CPR to ROSC in the equation 2 group and equation 1 group was much shorten significantly than that in the SDE control group(P＜0.01).To compare the equation 2 group and equation 1 group with the SDE control group：the average dose of the epinephrine was much reduced from initial stage applied with the epinephrine on CPR to ROSC(P＜0.05),but the cycle summation of apphcation epinephrine by mainline from the CPR initial stage to ROSC in the equation 2 group and equation 1 group was much significantly decreased than that in the SDE control group(P＜0.01).ConclusionsThe method of the epinephrine with graduate increased dosage by the equation G=(K+2n-1) mg/3min(K=1,2,n=1,2,3……,C≤0.2mg/kg)and aminophylline and sheng-mai injection with uniform method at the same time rapidly combination on CPR has better effects on increasing significandy the success rate of CPR,the survival rate,the time activity of success and shortening significantly time of the ROSC,improving brain and nervous system function.It can be new and effective method to increasing the success rate of resuscitation on the CPR.
