Key result
Resuscitation with phenylephrine or epinephrine resulted in 100% successful resumption of spontaneous circulation, compared to only 27% with isoproterenol in alpha-blocked dogs.
Why the study?
Does alpha receptor stimulation improve successful resuscitation compared to beta receptor stimulation in an asphyxiated dog model of cardiac arrest?
Does alpha receptor stimulation improve successful resuscitation compared to beta receptor stimulation in an asphyxiated dog model of cardiac arrest?
Absolute Event Rate: 100% vs 27%
Alpha receptor stimulation with concomitant diastolic pressure elevation is more important to the success of resuscitation from cardiac arrest than beta receptor stimulation in a dog model.
No takes yet. Share an insight, caveat, or question.
Alpha stimulation may aid resuscitation; leaves open translation from this animal model to clinical practice.
Yakaitis et al. (1979) studied Cardiac arrest. Phenylephrine (beta-blocked) or Epinephrine (unblocked) vs. Isoproterenol (alpha-blocked) was evaluated on Successful resumption of spontaneous circulation. Resuscitation with phenylephrine or epinephrine resulted in 100% successful resumption of spontaneous circulation, compared to only 27% with isoproterenol in alpha-blocked dogs.
