Sophisticated pharmacologic regimens help to maintain systemic perfusion pressure by increasing vascular tone as well as mediating positive inotropic effects.
Polymorphism found in the AFLP pattern of the hybrid suggested recurrent origin, segregation and/or backcrosses, although assessment of pollen viability indicated high male sterility.
Nevertheless, sufficient evidence demonstrating a survival benefit for any pharmacologic regimen is nonexistent.
In case pharmacological measures do not suffice mechanical cardiopulmonary support (MCS) may be used.
For pollen fertility analyses a few plants (5–12) per locality were selected.
Samples for AFLP analysis included not only the presumed hybrid populations and putative parents, but also plants of closely related aqueous solution of 8-hydroxyquinoline for 3 h, the root tips were fixed in a freshly prepared mixture of ethanol and acetic acid (3 : 1) for 1 h and stored in 75% ethanol.
An increasing number of introgression and hybrid speciation events have been documented, which prove that gene flow has obviously been underestimated when relying on morphology alone.
Transgression seems to be the rule rather than the exception (Rieseberg, Archer & Wayne, 1999).
comprises several diploid and tetraploid subspecies that are, except for the widely distributed typical subspecies, restricted to European mountain ranges.
Multivariate analyses were successfully employed for studies on morphological variation, as the subspecies differ almost exclusively in quantitative traits (Marhold, 1992, 1995, 1998, 1999; Marhold in the Pourret herbarium at MAF, which may be important for the typification, and thus proper interpretation, of this name.
MCS may be used during cardiopulmonary resuscitation or a “low-cardiac-output-syndrome” as bridging towards decision, recovery or long-term support.
Venoarterial extracorporeal membrane oxygenation (va ECMO) may take over cardiopulmonary function and may improve survival as well as neurological outcome after cardiogenic shock or cardiopulmonary resuscitation.
