anesthesiology management of intraoperative hypertension in children

BACKGROUND: Nebulized dexmedetomidine has been used for procedural sedation and allaying separation anxiety in children. Literature regarding its use in the attenuation of laryngoscopy and intubation response via the nebulized route is scarce. We evaluated preoperative dexmedetomidine nebulization on the hemodynamic response arising from laryngoscopy/intubation, hemodynamics, analgesic consumption, and postoperative sore throat. OBJECTIVES: The primary objective was to evaluate/compare the hemodynamic effects of preoperative intravenous and nebulized dexmedetomidine on laryngoscopy/intubation and compare the efficacy of the two routes in blunting the sympathoadrenal response...

BACKGROUND: Bradycardia in association with anaesthesia may have many potential causes and associated conditions, some rare and/or obscure. A prompt appropriate response is important as some homeostatic mechanisms may be impaired under anaesthesia. OBJECTIVES: To examine the role of a previously described core algorithm "COVER ABCD-A SWIFT CHECK", supplemented by a specific sub-algorithm for bradycardia, in the management of bradycardia occurring in association with anaesthesia...

A therapy refractory brain edema is causally responsible for the death of approximately 50% of patients following severe craniocerebral trauma. The development of a brain edema which cannot be controlled by conservative means is also the most frequent cause of death with cerebral emergencies not caused by trauma. The cerebral perfusion pressure (CPP), which is the decisive factor for sufficient cerebral oxygenation, can be calculated on condition that the mean arterial pressure (MAP) and the intracranial pressure (ICP) are continually monitored: (CPP = MAP-ICP)...
