Polyuria Associated With Dexmedetomidine in Operating Room

Sponsor: Hospital Privado de Comunidad de Mar del Plata

Summary

Dexmedetomidine is an a2-adrenergic receptor agonist drug, widely used in intensive care for the sedation of patients on mechanical ventilation, as well as in the operating room during invasive procedures and during general anesthesia. It also has anti-inflammatory properties and reduces the need for opioids and benzodiazepines, which leads to a lower incidence of delirium associated with these drugs. Among the frequent adverse effects associated with the administration of dexmedetomidine we can find bradycardia and hypotension, while some studies carried out in animals have shown that it can increase the diuretic rate. Polyuria related to pharmacological agonism of a2-adrenergic receptors has been described in vitro and in studies performed in animal models, and is believed to be the result of functional antagonism of arginine vasopressin. Despite its widespread use as a sedative and adjunctive anesthetic, there are very few reports in the literature of dexmedetomidine-related polyuria in humans. Currently there are no reports in the literature on the incidence of polyuria induced by the intraoperative administration of dexmedetomidine.
