There is evidence from several vascular beds that acute alcohol consumption causes ocular hypotension and peripheral vasodilatation.
Burn related upregulation of inducible nitric oxide synthase (iNOS) may produce peripheral vasodilatation, upregulate the transcription factor nuclear factor kappa B (NF-κB), and promote transcription and translation of numerous inflammatory cytokines.
Black women and Whites showed similar increases in heart rate and peripheral vasodilatation.
Black men, however, showed the smallest increases in heart rate in conjunction with an attenuated peripheral vasodilatation.
Most anesthetics cause peripheral vasodilatation and myocardial depression, also impairing kidney perfusion [86, 87].
Intra-arterial radiocontrast induced an early and short-lived (hours) increase in heart rate and cardiac output with peripheral vasodilatation.
VVS is a neurally mediated reflex syncope, consisting of a sudden drop in blood pressure with an associated fall of heart rate (HR); as a result of a peripheral vasodilatation and increase of vagal modulation, all these phenomena being regulated by the autonomous nervous system [2].
Much of the perceived benefit in acute reversal of severe acidemia is only based on animal and experimental studies, which demonstrated weakened end-organ response to catecholamines at pH < 7.2, with bradycardia, negative inotropism, impaired cardiac output, peripheral vasodilatation, and refractory hypotension [53].
The fundamental question of migraine pathogenesis, until now not clarified, is if pain has a peripheral (vasodilatation) genesis or is a central pain, that is without the need of a stimulus of vascular nociceptors provoked by vasodilatation or neurogenic inflammation (NI).
SS is one of the most complex hemodynamic failure syndromes, as it may imply derangement of all the three mainstays of cardiovascular homeostasis, each one to a variable degree: absolute or relative reduction in central blood volume, peripheral vasodilatation and myocardial failure may coexist and variably overlap in different phases of septic shock's course [3, 4].
Heat loss is determined by sweating, peripheral vasodilatation of the skin, insulation, ambient temperature, radiation to and from heat sources, and convection [30], [35].
