Hipotensión bajo anestesia regional subaracnoidea en población no obstétrica

Abstract

Introduction: regional 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. (English) [ABSTRACT FROM AUTHOR]
