The aim of this systematic review is to assess the safety of local anaesthetics (LA) combined with vasoconstrictors (VC) for patients with controlled hypertension undergoing dental procedures. A comprehensive search strategy were used to identify all relevant randomized controlled trials (RCTs) that evaluated the effect of LA combined with VC. All searches covered the period from 1990 to February 2021. We performed a meta-analysis using random-effect models and assessed overall certainty in evidence using GRADE approach. Our search strategy yielded 1262 references. Finally, seven randomised trials were included, but only three were included in the meta-analysis. The use of LA with VC may result in little to no difference in the heart rate (HR), systolic blood pressure (SBP) and diastolic blood pressure (DBP), but the certainty of the evidence was assessed as low. Death, stroke, acute myocardial infarction, need for hospitalization, pain and bleeding were not reported by the included studies. The hemodynamic changes using VC do not imply an increased risk of occurrence of adverse cardiovascular events. The use of VC could even be recommendable considering their multiple advantages.
FRISBEE RESUMENIntroducción: La adición de tratamiento antibiótico al tratamiento analgésico en el manejo postoperatorio de cirugía de terceros molares en pacientes sanos, ha sido propuesta principalmente para prevenir complicaciones postoperatorias. Sin embargo, es una terapia controvertida en la actualidad. Métodos: Realizamos una búsqueda en Epistemonikos, la mayor base de datos de revisiones sistemáticas en salud, la cual es mantenida mediante el cribado de múltiples fuentes de información, incluyendo MEDLINE, EMBASE, Cochrane, entre otras. Extrajimos los datos desde las revisiones identificadas, analizamos los datos de los estudios primarios, realizamos un metaanálisis y preparamos una tabla de resumen de los resultados utilizando el método GRADE. Resultados y conclusiones: Identificamos siete revisiones sistemáticas que en conjunto incluyeron ocho estudios primarios, de los cuales siete corresponden a ensayos aleatorizados. Concluimos que la adición del tratamiento antibiótico postoperatorio en cirugía de terceros molares en pacientes sanos, disminuye la incidencia de fiebre y probablemente disminuye el desarrollo de infección. Además, podría disminuir la inflamación, pero la certeza de la evidencia es baja. Finalmente, no existe claridad de que la adición de un tratamiento antibiótico postoperatorio en cirugía de terceros molares disminuya el dolor y otros efectos adversos ya que la certeza de la evidencia ha sido evaluada como muy baja.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
