Dexmedetomidine preconditioning protects against lipopolysaccharides-induced injury in the human alveolar epithelial cells

Rev. bras. anestesiol; 67 (6), 2017
Abstract Background and objectives Dexmedetomidine (DEX) has demonstrated the preconditioning effect and shown protective effects against organize injury. In this study, using A549 (human alveolar epithelial cell) cell lines, we investigated whether DEX preconditioning protected against acute lung injur...

Postpartum hemorrhage and pregnancy induced hypertension during emergency lower segment cesarean section: dexmedetomidine to our rescue

Rev. bras. anestesiol; 67 (5), 2017
Abstract Dexmedetomidine is a highly selective α-2 agonist which has recently revolutionized our anesthesia and intensive care practice. An obstetric patient presented for emergency cesarean delivery under general anesthesia, with pre-eclampsia and postpartum hemorrhage. In carefully selected cases ...

Dexmedetomidine protects against renal ischemia and reperfusion injury by inhibiting the P38-MAPK/TXNIP signaling activation in streptozotocin induced diabetic rats

Acta cir. bras; 32 (6), 2017
Abstract Purpose: To determine whether dexmedetomidine (DEX) could attenuate acute kidney injury (AKI) induced by ischemia/reperfusion (I/R) in streptozotocin (STZ)-induced diabetic rats. Methods: Four groups each containing six rats were created (sham control(S), diabetes-sham (DS), diabetes I/R (DI/R...

Impact of dexmedetomidine on amino acid contents and the cerebral ultrastructure of rats with cerebral ischemia-reperfusion injury

Acta cir. bras; 32 (6), 2017
Abstract Purpose: To investigate the effects of dexmedetomidine (DEX) on amino acid contents and the cerebral ultrastructure of rats with cerebral ischemia-reperfusion injury (I/R). Methods: Thirty-six, male, Wistar rats were randomly divided into three groups: the sham operation group (group C), the i...

Effect of dexmedetomidine on acute lung injury in experimental ischemia-reperfusion model

Rev. bras. anestesiol; 67 (2), 2017
Abstract Purpose: Ischemia-reperfusion injury is one of the consequences of tourniquet application for extremity surgery. The aim of the study was to establish the effect of dexmedetomidine on the acute lung injury following lower extremity experimental ischemia-reperfusion model in rats. Methods: Twen...

Effect of dexmedetomidine in children undergoing general anesthesia with sevoflurane: a meta-analysis

Rev. bras. anestesiol; 67 (2), 2017
Abstract Background and objectives: Sevoflurane is often used in pediatric anesthesia and is associated with high incidence of psychomotor agitation. In such cases, dexmedetomidine (DEX) has been used, but its benefit and implications remain uncertain. We assessed the effects of DEX on agitation in chil...

Perineural dexmedetomidine effects on sciatic nerve in rat

Rev. bras. anestesiol; 67 (1), 2017
Abstract The present study was designed to test the hypothesis that high dose dexmedetomidine would increase the duration of antinociception to a thermal stimulus in a rat model of sciatic nerve blockade without causing nerve damage. The rats were anesthetized with isoflurane. After electromyography (EMG...

Uso de la Dexmedetomidina en la Neurocirugía con el paciente despierto. A propósito de un caso clínico

Anest. analg. reanim; 29 (2), 2016
Presentamos el caso de un paciente de 58 años, coordinado para resección de tumor temporo insular izquierdo mediante una craneotomía despierto. Se analiza en este trabajo, a partir de la descripción del caso clínico, las ventajas de la resección de este tipo de lesiones con el paciente despierto. L...

Histopathologic comparison of dexmedetomidine's and thiopental's cerebral protective effects on focal cerebral ischemia in rats

Rev. bras. anestesiol; 66 (6), 2016
Abstract This study was designed to investigate whether dexmedetomidine and thiopental have cerebral protective effects after focal cerebral ischemia in rats. Thirty male Sprague Dawley rats were randomly assigned to three groups: control group (Group C, n = 10), dexmedetomidine group (Group D, n = 10), ...
