Abstract

GAYTAN-FERNANDEZ, Baruvi. Risks and complications during sedation for diagnostic endoscopy of the gastrointestinal tract without concomitant disease. Rev. mex. anestesiol. [online]. 2021, vol.44, n.3, pp.200-206.  Epub Oct 04, 2021. ISSN 0484-7903.

During sedation in endoscopic procedures of the lower and upper digestive tract, it is common for ventilatory and hemodynamic complications to arise. This article presents a review of the strategies to treat and prevent the most common ventilatory complications: laryngeal spasm, apnea due to intravenous anesthetic drugs and bronchospasm. Hemodynamic complications are also reviewed: vagal reflex and acute hypotension. A management algorithm is proposed which synthesizes and schematizes the prophylactic and therapeutic measures described in the bibliography, ordering them by their priority and effectiveness, allowing to clearly identify the degree of treatment necessary and the viability of the endoscopic procedure.

Keywords : Sedation; endoscopy; laryngeal spasm; drug-induced apnea; bronchospasm; vagal reflex; acute hypotension.
