The Thirst Axis

ADH (/vasopressin) is synthesised in the hypothalamus. From there it migrates in neurosecretory granules along axonal pathways to the posterior pituitary gland. Secretion of ADH is principally in response to changes in plasma osmolality. It acts on the collecting duct of the kidney to cause water reabsorption via the translocation of aquaporin channels in the CD lumen, and is therefore stimulated when we need to conserve water volume. It is stimulated by large falls in blood pressure or volume. At high concentrations, ADH also causes vasoconstriction.

Pre-eclampsia and Eclampsia

Pre-eclampsia and eclampsia are different stages of the same condition. Pre-eclampsia can result in eclampsia at any time. Eclampsia is immediately life-threatening and often symptomatic.   Pre-eclampsia is a condition characterised by increased blood pressure, proteinuria and often oedema during pregnancy. It is typically asymptomatic, and occurs after 20 weeks, although it rarely presents before 32 weeks – but when it does, it is associated with a worse prognosis.

Is adrenaline safe and effective as a treatment for out of hospital cardiac arrest?

Adrenaline (epinephrine) has been an integral component of advanced resuscitation algorithms since the early 1960s. Initial guidelines for the treatment of cardiac arrest recommended the use of intracardiac adrenaline (0.5 mg) or high dose intravenous adrenaline (10 mg), repeating with larger doses if required.1 The mechanism of action for adrenaline in cardiac arrest is attributed to stimulation of α2 receptors in vascular smooth muscle, causing vasoconstriction. This increases aortic diastolic pressure, which in turn leads to increased coronary perfusion pressures, which improves short term survival. Experimental studies, however, suggest that adrenaline impairs cerebral macrovascular2 and microvascular blood flow,3 4 increases ventricular arrhythmias, and increases myocardial dysfunction after return of spontaneous circulation.5 This creates the paradox of better short term survival but at the potential cost of worse long term outcomes.
