Vasopressin and Arterial Pressure Regulation
Data from conscious rats, dogs, and humans show that plasma arginine vasopressin (AVP) begins to exert vasoconstrictor activity at concentrations in the same range as those associated with maximum antidiuretic activity. Minimum pressor responses are observed with elevated plasma AVP, due in part to decreases of cardiac output and in part to withdrawal of sympathetic neural tone to various regio...
متن کاملLATE ARTERIAL REPAIR FOR LOWER LIMB OR KNEE SALVAGE
The objective of this report is to prove that even after development of ischemic necrosis of the muscles and nerves, we can still save the extremity or the knee and even several days after arterial injury, perform arterial repair and other mentioned procedures. Thus we can retain a functionally satisfactory leg or knee joint, which is far better than classic above-knee amputation and utili...
متن کاملCentral vasopressin raises arterial pressure by sympathetic activation and vasopressin release.
Although central administration of arginine vasopressin (AVP) has been reported to increase arterial pressure mediated by activation of the sympathetic system, we found that peripheral blockade of sympathetic transmission did not attenuate this pressor response. To elucidate the mechanism, rats were pretreated with either phentolamine (3 mg/kg), chlorisondamine (2.5 mg/kg), a vasopressin V1 rec...
متن کاملResponse of the limb vascular bed in man to intrabrachial arterial infusions of hypertonic dextrose or hypertonic sodium chloride solutions.
Infusions of hypertonic dextrose or NaCl solutions reduce resistance in several vascular beds of experimental animals. To study the response in man, 60 intrabrachial arterial jet infusions of hypertonic dextrose solution or hypertonic NaCl solution, each at 3 dose levels (1, 2, and 4 milliosmols/min), were made in 19 male student volunteers aged 21 to 29 years. Limb blood flow was measured by c...
متن کاملHemodynamic and metabolic effects of low-dose vasopressin infusions in vasodilatory septic shock.
OBJECTIVE To investigate the physiologic effects of exogenous vasopressin as a potential alternative to traditional high-dose catecholamine therapy for septic patients with vascular hyporeactivity to catecholamines. DESIGN Prospective, case-controlled study. SETTING Intensive care unit of a university hospital. PATIENTS Vasopressin was infused in 16 critically ill septic patients who rema...
