Return of spontaneous circulation, recurrence of asystole after resuscitation, hemodynamic metrics, arterial blood gas values, neurological assessment score and indexes of pulmonary transudation were recorded. In experiment B, rats using the same model and resuscitation protocol were randomly divided into 21 groups: Control 0, Control 20, Control 40, Control 60, Control 80, Control 100, Control 120, LCT 0, LCT 20, LCT 40, LCT 60, LCT 80, LCT 100, LCT 120, LCT/MCT 0, LCT/MCT 20, LCT/MCT 40, LCT/MCT 60, LCT/MCT 80, LCT/MCT 100 and LCT 120 (n=10, the subscripts represent respective endpoint of observation in minutes). Myocardial bioenergetics were determined.Results: In experiment A, the LCT and LCT/MCT groups had a shorter time to return of spontaneous circulation (ROSC) (P=0.001and P< 0.001, respectively) and higher survival rate (P=0.033 and P=0.014, respectively) compared with the Control group. The LCT/MCT group had higher MAP (P< 0.001 and P=0.001, respectively), HR (P< 0.001 and P=0.004, respectively) and RPP (P< 0.001 and P< 0.001, respectively) compared with the Control and LCT groups, respectively. In experiment B, the LCT/MCT group had a higher energy charge compared with the control group at 20 (P< 0.001) and 40 (P< 0.001) minutes. The LCT group had higher energy charge compared with the Control group at 40 (P< 0.001) and 60 (P< 0.001) minutes.Conclusion: The supplement of lipid emulsion to epinephrine improves resuscitation outcomes of asphyxia-induced cardiac arrest than epinephrine alone in our in vivo model of aged rat. LCT/MCT emulsion may be superior to LCT emulsion in epinephrine-based resuscitation.Keywords: asphyxia, cardiac arrest, epinephrine, lipid emulsion, cardiopulmonary resuscitationHuang LRen QYu SShao YChen YHuang XDove Medical Pressarticleasphyxiacardiac arrestepinephrinelipid emulsioncardiopulmonary resuscitationGeriatricsRC952-954.6ENClinical Interventions in Aging, Vol Volume 15, Pp 1701-1716 (2020)
