ETOMIDATO MECANISMO DE ACCION PDF

Si hay tumor residual, se puede emplear la radioterapia sobre el lecho tumoral. Prognosis is extremely poor and survival is short. Diagnosis should be based on clinical,biochemical, and morphological data. Clinical findings may be fairly innocuous, although hormone overproduction is sometimes found.

Uso de dexmedetomidina em anestesiologia. Dexmedetomidine in anesthesiology. Uso de dexmedetomidina en anestesiologia. Os pacientes sedados com a dexmedetomidina podem ser despertados, quando solicitados, e tornarem-se cooperativos.

It has important sedative and analgesic effects, good hemodynamic control at stress situations and may, by itself, induce anesthesia. This drug has been used to promote postoperative and intensive care sedation and analgesia. Due to such properties, dexmedetomidine has recently become a co adjuvant drug for anesthesia. So, this is a review of the literature about dexmedetomidine in anesthesia. Action mechanisms of a 2 -adrenergic agonists and dexmedetomidine pharmacokinetic and pharmacodynamic properties are also reviewed in this paper.

Anesthetic consumption is decreased during anesthesia. Patients sedated with dexmedetomidine may awake, when requested and become cooperative. Even high dexmedetomidine doses do not cause respiratory depression.

Bradycardia is a frequent side effect which may be minimized by slow drug infusion. So, dexmedetomidine is an important additional resource to anesthetic practice that may be used in different patients and surgical procedures.
