Differences between protocol and review

Changes have been made between the current review and the original protocol. These changes include the following.

  1. Based on comments from a peer reviewer (Peter Alston), the title was changed from 'Alpha‐2 adrenergic agonists for the prevention of cardiovascular complications among patients undergoing cardiac or non‐cardiac surgery' to 'Alpha‐2 adrenergic agonists for the prevention of cardiac complications among patients undergoing surgery'.

  2. We performed several post‐hoc analyses that were not specified in the original protocol.

    1. A subgroup analysis was performed based on drug type to explain the moderate heterogeneity (I2 = 34%) for the pooled effect of α‐2 adrenergic agonists on perioperative hypotension.

    2. We performed a post‐hoc subgroup analysis based on surgical procedure to explain the significant heterogeneity (I2 = 54%) for the pooled effect of α‐2 adrenergic agonists on perioperative bradycardia.

    3. Given the large influence of a single RCT of mivazerol (Oliver 1999), we performed a post‐hoc sensitivity analysis that excluded this study.

  3. We have added acute stroke as a secondary outcome (side‐effect from treatment) based on comments from a peer‐reviewer (Helen Higham) and the results of the POISE trial (POISE 2008). Specifically, the POISE trial found that perioperative beta‐blockers caused a significantly increased risk of perioperative acute stroke.

PICO

Population
Intervention
Comparison
Outcome

El uso y la enseñanza del modelo PICO están muy extendidos en el ámbito de la atención sanitaria basada en la evidencia para formular preguntas y estrategias de búsqueda y para caracterizar estudios o metanálisis clínicos. PICO son las siglas en inglés de cuatro posibles componentes de una pregunta de investigación: paciente, población o problema; intervención; comparación; desenlace (outcome).
