All About Clonidine and its Role in Preventing Hematoma Following Aesthetic Facial Surgery: A Narrative Review With Practical Guidance

Abstract

Postoperative hematoma remains the most common major complication following face and neck lift surgery, with decades of literature highlighting perioperative hypertension and sympathetic surges as primary modifiable risk factors. Clonidine, a centrally acting alpha-2 adrenergic agonist, has been progressively incorporated into facelift protocols to stabilize postoperative blood pressure and blunt sympathetic activation. This narrative review examines the pharmacology of clonidine, the pathophysiology of post-facelift bleeding, and the clinical evidence supporting clonidine's role in perioperative blood pressure management. Practical dosing strategies, contraindications, and safety considerations are presented based on the available literature and the authors’ clinical experience. When used in a comprehensive perioperative blood pressure management protocol, clonidine appears to be a safe and effective adjunct for hematoma prevention in aesthetic surgery, though the supporting evidence is predominantly Level IV (retrospective series and observational studies) supplemented by expert opinion. Practical dosing strategies, contraindications, and safety considerations are presented based on the available literature and the authors’ clinical experience.
