Why the study?
Does epicardial painting with phenol effectively and specifically produce regional cardiac sympathectomy in anesthetized dogs?
Does epicardial painting with phenol effectively and specifically produce regional cardiac sympathectomy in anesthetized dogs?
Epicardial phenol application produces effective regional sympathectomy, but its effects extend beyond the treated area, complicating the selection of adjacent control regions in experimental models.
No takes yet. Share an insight, caveat, or question.
Risks non-specific denervation beyond treated epicardium in canine models; leaves open refined controls for regional sympathectomy studies.
Mori et al. (1989) studied this question.
