Fenilefrina y efedrina en embarazo de alto riesgo / Phenylephrine and Ephedrine in High-Risk Pregnancies

Comparación de fenilefrina y efedrina en el tratamiento de hipotensión inducida por raquia en embrazo de alto riesgo. Revisión narrativa
Comparison of Phenylephrine and Ephedrine in Treatment of Spinal-Induced Hypotension in High-Risk Pregnancies: A Narrative Review.
Front Med (Lausanne). 2017 Jan 20;4:2. doi: 10.3389/fmed.2017.00002. eCollection 2017.
Abstract
PURPOSE: To compare maternal and fetal effects of intravenous phenylephrine and ephedrine administration during spinal anesthesia for cesarean delivery in high-risk pregnancies. SOURCE: An extensive literature search was conducted using the US National Library of Medicine, MEDLINE search engine, Cochrane review, and Google Scholar using search terms "ephedrine and phenylephrine," "preterm and term and spinal hypotension," "preeclampsia and healthy parturients," or "multiple and singleton gestation and vasopressor."  PRINCIPLE FINDINGS: Both phenylephrine and ephedrine can be safely used to counteract hypotension after spinal anesthesia in patients with uteroplacental insufficiency, pregnancy-induced hypertension, and in non-elective cesarean deliveries. Vasopressor requirements before delivery in high-risk cesarean sections are reduced compared to healthy parturients. Among the articles reviewed, there were no statistically significant differences in umbilical arterial pH, umbilical venous pH, incidence of fetal acidosis, Apgar scores, or maternal hypotension when comparing maternal phenylephrine and ephedrine use. CONCLUSION: From the limited existing data, phenylephrine and ephedrine are both appropriate selections for treating or preventing hypotension induced by neuraxial blockade in high-risk pregnancies. There is no clear evidence that either medication is more effective at maintaining maternal blood pressure or has a superior safety profile in this setting. Further investigations are required to determine the efficacy, ideal dosing regimens, and overall safety of phenylephrine and ephedrine administration in high-risk obstetric patients, especially in the presence uteroplacental insufficiency.

Abstract
BACKGROUND:
Although studies have shown increased rates of chondral injury with delayed surgical treatment of pediatric anteriorcruciate ligament (ACL) injuries, it is unknown if this is related to a delay in diagnosis and appropriate activity restrictions. The purpose of this study was to determine if the time from injury to diagnosis, time from diagnosis to reconstruction, and preoperative activity level correlate with the degree of cartilage injury seen intraoperatively.
CONCLUSIONS:
Diagnosis of ACL rupture within 6 weeks of injury and surgical reconstruction within 6 weeks of diagnosis or 12 weeks of injury do not appear to affect the rate of cartilage injury in skeletally immature patients. Weight-bearing status, brace use, and participation in athletic activities between the time of injury and diagnosis also did not impact the rate of intra-articular injury following ACL tear.
Resumen
ANTECEDENTES:
Aunque los estudios han demostrado un aumento de las tasas de lesión condral con tratamiento quirúrgico retrasado de lesiones del ligamento cráneo anterior (ACL) pediátrico, se desconoce si esto está relacionado con un retraso en el diagnóstico y restricciones de actividad apropiadas. El propósito de este estudio fue determinar si el tiempo desde la lesión hasta el diagnóstico, el tiempo desde el diagnóstico hasta la reconstrucción, y el nivel de actividad preoperatoria se correlaciona con el grado de lesión del cartílago observado intraoperatoriamente.

CONCLUSIONES:
El diagnóstico de la ruptura del LCA dentro de las 6 semanas de la lesión y la reconstrucción quirúrgica dentro de las 6 semanas del diagnóstico o las 12 semanas de lesión no parecen afectar la tasa de lesión del cartílago en pacientes esqueléticos inmaduros. El estado de carga, el uso de la ortesis y la participación en actividades atléticas entre el momento de la lesión y el diagnóstico tampoco influyeron en la tasa de lesión intraarticular después del desgarro del LCA.
LEVEL OF EVIDENCE:
Level IV.
