espanolla anestesia regional subaracnoidea es una tecnica muy util; sin embargo, su principial efecto secundario afecta el sistema cardiovascular. Los estudios en poblacion no obstetrica son escasos; la variedad de comorbilidades y tipos de pacientes dificultan el diagnostico y manejo. Objetivo: revisar la fisiopatologia, enfatizar en factores de riesgo y actualizar el manejo de la hipotension bajo anestesia subaracnoidea en pacientes no obstetricos. Metodologia de Busqueda: se realizo una busqueda en las bases bibliograficas PubMed, Science Direct, EbscoHost, MEDLINE; se excluyeron aquellos articulos que incluian unicamente poblacion obstetrica. 63 articulos cumplieron los criterios. Conclusiones: los factores de riesgo identificados fueron edad, estado fisico previo, hipertension y obesidad. Aunque no hay consenso en el manejo, identificar pacientes en riesgo permite la intervencion preventiva y tomar decisiones que disminuyan complicaciones mayores. Los liquidos intravenosos como co-carga mantienen vigencia. El uso de vasopresores profilacticos debe limitarse en pacientes con factores de riesgo.

Vasoconstrictores Englishregional subarachnoid anesthesia is a very useful technique. however, the leading side effect affects the cardiovascular system. Few studies regarding non-obstetric population are published. Comorbidities and the variety of patients make the diagnosis and management difficult to establish. Objective: to review physiopathology, and emphasize risk factors and management of hypotension under regional spinal anesthesia. Searching Methodology: literature search was performed using PubMed, Science Direct, EbscoHost and MEDLINE; those exclusively including obstetric population were excluded. 63 articles matched the criteria. Conclusions: the risk factors that were identified were age, physical status, hypertension and obesity. Although there is no consensus in the management protocol, identifying these patients at risk allows a preventive intervention and the taking of measures that avoid major complications. Intravenous fluids as co-loading still remain valid; vasopressors should be limited to patients at risk. MED.UIS. 2017;30(1):73-8.Keywords: Anesthesia, Spinal. Hypotension. Vasoconstrictor Agents.
