Endotracheal lidocaine in preventing endotracheal suctioning-induced changes in cerebral hemodynamics in patients with severe head trauma.

摘要: Introduction In patients with severe head trauma, endotracheal suctioning can result in adverse reactions including cough, systemic hypertension, increased intracranial pressure, and reduced cerebral perfusion pressure. The aim of this prospective, blinded clinical trial mechanically ventilated trauma whose cough reflexes were still intact was to assess the effectiveness endotracheally instilled lidocaine preventing suctioning-induced changes hemodynamics (increase pressure pressure) after a single suctioning.
