Advent of New perioperative care for fluid management after cardiovascular surgery: A review of current evidence. J Cardiol. 2020 Jan 21;: Authors: Nishi H Abstract Fluid management with diuretics is a key factor for postoperative management following cardiovascular surgery, and it is common to administer intermittent doses of diuretics and fluids in the early postoperative stage as primary therapy. Loop diuretics are usually given as the first option, followed by an aldosterone blocker, mannitol, and human atrial natriuretic peptide (hANP) or recombinant human B-type natriuretic peptide infusion. Although the effects of tolvaptan, a new type of diuretic with an aquaretic effect to increase urine volume without increasing electrolyte excretion into urine by blocking the vasopressin V2 receptor, on congestive heart failure are well known, it has not been established whether advantages may also be recognized in the volume overload in early postoperative stage after cardiac surgery. In this review, we clarified the efficacy of tolvaptan as the advent of new fluid management after cardiovascular surgery. Tolvaptan has advantageous effects for immediate body weight reduction in patients with positive postoperative water balance following cardiac surgery. This immediate volume reduction could help recovery of respiratory dysfunction due to lung edema. Also, hypernatremia was rarely seen; therefore, it can be used safely during postoperativ...
