Examining the effects of dexmedetomidine on eye pressure during spine surgeries

Effects of Systemic Administration of Dexmedetomidine on Intraocular Pressure During Scheduled Spine Surgeries in a Prone Position. Prospective, Randomized, Double-blinded Study.

NA · Attikon Hospital · NCT04628663

What this trial studies

This clinical trial investigates how dexmedetomidine, a sedative, affects intraocular pressure (IOP) in patients undergoing elective spine surgeries while in a prone position under general anesthesia. It is a prospective, randomized, placebo-controlled, double-blinded trial involving adult patients classified as ASA physical status I, II, or III. Participants will be randomly assigned to receive either dexmedetomidine or normal saline, with IOP measurements taken during the procedure to assess the drug's impact. The study aims to provide insights into managing IOP during surgeries that may pose risks to patients with eye conditions.

Who should consider this trial

Good fit: Ideal candidates include adult patients scheduled for elective spine surgery in a prone position under general anesthesia.

Not a fit: Patients with previous eye surgery, preexisting eye diseases, or unstable hemodynamics may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved management of intraocular pressure during spine surgeries, potentially reducing complications for patients with eye concerns.

How similar studies have performed: While the specific use of dexmedetomidine for IOP management during spine surgery may be novel, similar studies have shown promising results in other surgical contexts.
